CM7 RC1 Experience

Hi all, this is my first post and I'm a n00b to rooting, but don't let that stop you from reading on since I'm an advanced user and hope I can add some value here. Honestly, don't know what took me so long to do this. Posting to the Q&A forum since I can't yet post to the RC1 Dev forum.
My main goals for rooting were to get out from under Sprint's downgrade of my Swype beta (I should never have installed that OTA update, duh), upgrade to GB, and get better performance (battery especially).
I tried lots of the GB ROMs so far and experienced some of the reported problems like cycling reboots, slow/non-responsive market, CM skate anim cycling, etc. Some ROMs had swype, some didn't and most produced the licensing issue discussed in these forums when trying to install the latest beta.
Long story short, I've found a very stable and fast performing combo that I thought I'd share, and ask a question about. Here's what I did:
In recovery, Format_all, wipe data, system, cache, dalvik.
Install RC1, install the latest GB google apps and restart.
3G performance was piss poor, and I want wimax (more Geeees!), so I installed the toast wimax kernel (and antipasto font which I'm loving), cleared caches again, restarted and now 3G performance was faster than I think it has ever been. [EDIT: WiFi now an issue] and GPS are fast and stable. Best part, I was able to download and install the very latest Swype beta on this ROM.
A couple things that need addressing though:
'Cell standby' is a somewhat high percentage battery drain which I'll try to tackle through other reported methods (could be wimax searching/standby?). That said, battery life is still very good and way better than sprint/sense, even under heavy/constant use.
USB issues: Enable USB debugging and notify. Icon shows in notification bar. Disable debugging, but leave notify checked. Debugging icon still shows. Tied to this is the inability to select the mount/charge options, which others have recently reported in the RC1 Dev forum. So can't mount to PC. Any updates on how to resolve?
WiFi is now non-functional on my office AP.
WiMax control settings not showing up since they aren't there with this ROM/kernel combo for some reason. Any/all ideas welcome on this point too.
Slow market downloads, even though speedtest shows 527kbps down.
Thanks again everyone for this great community!

I haven't had any luck with my phone on my office AP (3COM) since I got this darn phone. For some odd reason it gets the wrong gateway and I have to set it up manually from the terminal if I want to use it after connecting. Check your gateway when you connect and see what you are getting.

WiMax isn't in RC1 yet. You can get an alpha build that Shinzul has up. Or wait until the Final release which should have WiMax and HDMI working.

Thanks, I'll check the gateway, and will check out Shinzul's alpha.
Had my first auto reboot today, and Sms is not working right (yes, less than 160 chars and not mms). Might have spoken too soon about this combo...

Keep in mind that the "Percentages" will always total a 100%. Something will always be big.
So to me I WANT TO See Cell Standby be high. That means nothing stupid in the OS is chewing it up. And Cell Standby isn't effected all that much except the Radio Firmware (and settings) !! So be careful what you wish for.

The problem for me is, on sense you can uncheck radio always on to remove that cell standby huge drain. On froyo you can use juice defender. But on cm7 you can do neither. So I need to turn it on and off manually. Very annoying, anybody have a solution?

If you install CM7 nightly build #6 (today's build), it now has support for WiMax and SMS splitting.

juice defender is failing me. and i reeeeeallly hate turning data on and off manually. any suggestions? i'm new to aosp so i'm a bit lost rigt now.

Just use the expanded notification bar and toggle data. You're not gonna be able to shut off the radio without airplane mode.

Unfortunately I think some permissions changed within Android 2.3 which CM7 uses and JuiceDefender just doesn't work on it yet. You're only other option is to flash CM6 (Android 2.2) if you must have JuiceDefender working in ASOP.

ya it looks like thats the case. sucks cause it is taking a really high toll on my battery. i hope somebody will put it into one of the next builds soon.

Continuing from my OP, I'm now off RC1 and onto Nightly #12 with WiMax. WiMax when on is a huge battery drain and I'll be doing some post-reading to figure out if someone has found a way to set a WiMax antenna polling frequency so that it can sleep for periods when not connected.
That said, the WiMax is nice and fast...so I only enable it with the notification bar widget when I need speed or talk/data simultaneously. I also use a new version of Setting Profiles (Full version) to toggle the Wimax on/off based on where I am -- note that this is a test version sent to me by the developers as I've been helping them test this feature. So I don't know if it's in the latest market release version, but if you are a paid owner of that app, just email them and ask for it (although the updated market release is likely not far off if it's not out already).
With the XDA-sponsored SetCPU on and no WiMax, I'm actually getting great standby times in the double-digit number of hours, which has been a first for me with this phone! I know there are some great posts out there about manual conditioning of the battery, which I'm eager to try, and other useful battery-related posts.

I am running CM7 RC1 and I have to say I love it. The first couple of days after flashing I was experiencing terrible battery life. I mean 5 hours or less. I finally flashed Savage-Zen kernel and used the "smartass: governor in CM settings. My battery was better, but Cell Standby was still draining all the battery. I wiped the dalvik cache again and it helped some. but I think the best thing I did was disable google backup settings. Keep in mind before I flashed the kernel and battery life was horrible I wasnt using it heavily, WiFi was off completely, I toggled mobile data on and off as needed, and didnt let anything except for weather autosync. I had maybe 10 applications as well. Once I flashed Savage-zen, used smartass, and disabled Backup data to google servers. MY battery lasts over 2 days with moderate usage with mobile data always on and gmail and weather auto synced.
As far as bug-wise, the only thing I have experienced so far is sometimes there is a slight delay when unlocking the phone and getting the lockscreen to show. Sometimes when the button is pressed to unlock, the bottom touch buttons light up, but the lockscreen takes like 5 seconds to appear.
One more thing is the GPS icon stays in the notification area once it has been turned on and back off.
All in all I can say now that I have amazing battery life, I love CM7 and will not use anything else besides CM7. I cannot wait until the stable release is out. GO CyanogenMod Team!

[GUIDE] Improving battery life for non-TW ROMs

A bit dated of a post, but most if not all still relevant. We have a lot of non-TW ROMs for this phone which sacrifice battery life for improved functionality, not by choice, but mainly because Samsung's lack of GPL compliance with regards to sharing kernel sources. Our community devs have done an incredible amount of work with their kernel forks, but Samsung's paid development teams obviously have a lot more time and incentive to work on it, and as such our community devs' graciously find even more fixes once source drops, then merge them into the community kernels we're all using. So as we wait in limbo for them to share their JB kernel contributions to our community:
Anyone that wants to add anything to the list, post to the thread and I'll keep collecting.
Workarounds for D710 battery drainers:​
battery saver scripts:rmikulus found this sweet piece of development gold: if you know how to run scripts,"Die Hard Battery Calibrator" will calibrate your battery in only about 20 minutes (must be plugged in that entire time)
Probably better to use the latest and greatest here instead, much easier to install, just a simple CWM zip AIO scripts:
Jelly Bean Tweak Pack for Epic 4G Touch Fixes Various Errors
--appears to help battery life and other various issues.
Voodoo LOUDER (paid) supercurio - Project Voodoo
--not battery-related, probably causing opposite effect actually, but many find an issue with headphone audio being maxed out at lower dB than desired. I'll confirm this works on CM10 nightlies.
WiFi : Turn it off when not in use, just like anything else. Tasker does a great job of automating this process.
raise the network scan interval to reduce background wifi radio usage (Rom Toolbox allows build.prop tweaks such as this,)
change the sleep policy for the wifi to Never While Charging to allow wifi connection to die when phone is off (toggle is in the touchkey menu while viewing wifi settings.)
NOTE: WiFi is a more desirable data connection than 4G as far as batt life is concerned. 4G is auto disabled when wifi is on for most ROMs. 4G (WiMax) is a new technology that still has yet to be perfected, not unlike these latest developments in ICS.
4G Radio: Also turn off when not in use. Use the latest modems available. Note that modems won'tt install from ODIN/mODIN flashes, gotta use CWM zip installs.
Haptic Feedback: Turn off haptic feedback, vibration kills. (Particular to CM9 ROM, haptic is set too strong right now, TouchWiz-based ROMs are fine, but if you can live w/o it...)
LED notifications: Another wakelock offender. Turn them off for now, it's one of the reasons the device stays awake when it should be sleeping. Sleep is good.
Get BetterBattery Stats by chamonix : Take a look at it after a long period of uptime without restarting (quick or full) to allow a greater set of data to parse into stats. Some apps you use may be eating away at your battery from the background. Spare Parts Plus and it's root-friendly brother BladeBuddy is also valuable.
Use the latest kernels available. If you're flashing CM nightlies, you're good to go, kernel modifications are updated in the same process.
Touch sounds and screen lock sound: These still cause partial wakelocks , leading to some amount of battery drain. System Settings>Sound menu to turn these off for now. (thx coiledwire)
The CM9 Team put together a similar list with a few things not listed here. Check the 'Power Saving Options' section on the CM9 Blog
----
Android-specific:​
BatteryStats.Bin This little file keeps a record of your battery usage, power amperage, etc. and every time you flash a rom, it gets wiped. The system's ability to track the exact power level of your battery is DIRECTLY dependent on this file, so if you don't allow the newly flashed system a few days to calculate averages over time, it won't really have time to realize how charged it really is. NOTE: this file has NOTHING to do with improving battery life, only calculating what the battery % shows in the statusbar (and in the battery statistics charts in the system settings menus.) I've sat at 5% battery life for an entire hour with screen on surfing the 'net. No way it was really 5% that entire time.
While wiping battery stats won't increase battery life, it will improve the calculation of the charge, if done properly. Stats are saved in /data, when a ROM is installed, initially the stats will not have much data to extrapolate from, and the battery probably isn't entirely full to begin with, therefore making a mess of a new ROM's recognition of the cell's true charge. It's best to wipe stats when your charge is above 4180mV (E4GT stock battery size.) I've seen mine as high as 4202mV. Also, if you've got aftermarket cells that aren't the same mAH rating, the results will be slightly wonky. Battery Calibration app can set a reminder to flush the battery stat counter file when the phone is charged, if you need to charge with your device on.
I notice that flashing roms with a battery @100% and charging will help in this regard, then once the system is fully booted, unplug it and drain it to 15%, then charge to 100%, then do :
Bump Charging is suggested by HTC developers to potentially DOUBLE your battery life.
Battery Tuning: We're running Lithium Ion batteries. Don't kill it to 0%. Ever. Tip: Condition your new cell phone’s battery to make it last longer (but be sure to condition it properly)
Live Wallpapers and other background services: If you can live without them, turn off the services. Many common apps trigger network connections on a periodic schedule, further causing drain. increase sync periods, or just sync manually.
Sync: Yet another form of background services. If your sync is running all the time from frequent emails, gvoice msgs. etc... and the like, try turning off some of your heavier data tranx and refreshing manually when you need it.
Again, please tack on posts for this thread if you have good additions to make, I'm just trying to collect a one-stop shop of battery life savers, and a place to point newbs when they start trainwrecking dev threads with questions about it. This is my humble way of giving back cuz I was one at one point.

Thanks, some of these tips most users may know but the one that helpped me was the notification light when running cm9! I worked 10 hours a day and cant use my phone but my battery was draining like crazy! Much better!

Solid advice. I do everything mentioned here. I also throw in a bump charge to finish it off..old habits die hard

so is bump charging still a valid method? I've read that HTC developers suggest it, but you're saying old habits so I'm assuming you're aware of something about it.

Well, its just my routine. I charge to full, power down charge to full, unplug, power on, plug back in. When. I open Battery Calibration app, if battery shows 100% but only like 4110mV instead of 4180mV+ I will unplug and plug back in a minute later then wipe stats when it shows anything over 4175mV and 100% charge...confusing enough?! Lol

Thanks For the Guide.
I was really dissapointed with ICS.
I was still running EL29- Rooted and was running everyday on 14hrs with Wi-Fi always on. so after seeing that most bugs were fixed on FD24 i updated and yesterday i was running on 5hrs tops with Wi-Fi on.
So i did some suggested tweaks.
Wi-Fi off.( only ON when i need it)
GPS- I unchecked the last to option on the location.
Adjust haptic
uncheck some Sync from Google.
by the way what's? "Internet Sync"
and now.... im at 66% after 7hrs of being unplugged.

Internet sync meaning anything that may transfer data in the background like google talk, weather apps, Skype, etc.
Glad to hear those stats ! Take a screen Cap of the battery stats when it gets below 10% and post here

We're currently in a lull period between development phases now that ICS is blowing up all of our E4GT's. Samsung's kernels leave a lot to be desired, hence the current work towards a proper aftermarket kernel. ICS roms are very new, especially the custom ones going on in the dev kitchen right now. Software level ROM coding is one thing, the devs will get that fixed, but ultimately they're dependent on a solid kernel... and one of the biggest problems with the kernel, is that ever-elusive battery life.
so:
God-Tier devs, correct me if I'm wrong, and please add your thoughts, additions, and suggestions below. I'll try to keep a live OP post for a universal E4GT battery tweak guide.
Things that eat up our E4GT battery for now, with workarounds:​
WiFi : Turn it off when not in use
raise the network scan interval (Rom Toolbox allows build.prop tweaks such as this,)
change the sleep policy for the wifi to Never While Charging to allow wifi connection to die when phone is off (in spare parts).
NOTE: WiFi is a more desirable data connection than 4G as far as batt life is concerned. 4G is auto disabled when wifi is on for most ROMs.
4G: Also turn off when not in use. Use the latest modems available. Flash with odin/mobileOdin because the CWM flashables sometimes don't stick.
Haptic Feedback: Turn off haptic feedback, vibration kills. (Particular to CM9 ROM, haptic is set too strong right now, TouchWiz-based ROMs are fine, but if you can live w/o it...)
LED notifications: Another wakelock offender. Turn them off for now, it's one of the reasons the device stays awake when it should be sleeping. Sleep is good.

Some apps you use may be eating away at your battery from the background. Spare Parts Plus and it's root-friendly brother BladeBuddy is also valuable.
Suggestion, with disclaimer: Use the latest stock or Rogue kernels and modems. sfhub keeps the most updated modem D/L list . Don't forget that you should not flash ANYTHING from ICS kernel/recoveries yet!!! There are known issues with these kernels, and every last one of them is a beta stage leak from samsung along with a custom recovery and some little tweaks to work with the various ICS roms. The flashing HAS bricked MANY phones! There will be great fanfare and notices from the developer teams once we have an ICS kernel that works. It's mostly dependent on Samsung releasing sourcecode, although there are some teams working on porting the source of the other Galaxy II's... the race is on!
Touch sounds and screen lock sound: These currently cause partial wakelocks in Galaxy S2 ICS ROMs , leading to some amount of battery drain. System Settings>Sound menu to turn these off for now. (thx coiledwire)

Universally true:​
Live Wallpapers: If you can live without electricsheep or the other various animated wallpapers, do so. I can't
Battery Tuning: If you didn't condition your battery when you first got it, good luck. In any event, try to condition it from here on out by burning it out completely (phone won't boot with it) then charge 100%, keep it off charge until it dies again, CWM Wipe Battery Stats, run the battery down again without charge. Repeat the charge/kill cycle a couple times. New kernel or ROM? Start from scratch again. Battery stats are saved in /data, so old stats can mess with a new ROM's recognition of the cell's true charge. Also, if you've got aftermarket cells that aren't the same mAH, you'll only get as good a conditioning as the weakest battery can take. Battery Calibration app can set a reminder to flush the battery stat counter file when the phone is charged, if you need to charge with your device on.
Sync: If your sync is running all the time from frequent emails, gvoice msgs. etc... and the like, try turning off some of your heavier data tranx and refreshing manually when you need it.
EDIT:
Darchstar and the CM9 Team put together a similar list with a few things not listed above. Check the 'Power Saving Options' section on the [url="http://e4gtcm.blogspot.com/p/customization-guide.html] CM9 Blog[/url]
I've also since learned that wiping battery stats does nothing with prolonging battery life. There's numerous articles quoting official Google/Android developers where they explain this flat out It may help your system recognize the true percentage of your charge, but that's about it.

Some of us have flash addiction. Some of us enjoy bring Guinea pigs for development. I for one just left my last phone running cm7 and couldn't bear the austerities of a stock ROM. The GB twiz hacks are alright, but it doesn't feel like home to me.

Agree with just about everything. One thing that I disagree with is letting your battery die at all. It actually decreases the life of the battery in lithium ion batteries. Its an old school method for old batteries. Try never going under 15% if possible. Everything else is correct as far as I can tell.

On the topic of battery calibration, if you know how to run scripts, the creator of V6 Supercharger and 3G Turbocharger scripts has also created "Die Hard Battery Calibrator" which will calibrate your battery in only about 20 minutes (must be plugged in that entire time)

T989 Nexus Rom battery drainage issue plus more

so I flashed the Nexus Rom as well as the newly updated 3.8 version with the battery % feature flashed on my phone. The entire procedure was done as instructed (restore/clear 3+ times on everything as instructed) and I waited well over 10 minutes upon a reboot. So all is set and almost everything is working flawlessly.
There are few issues, however, which I'm curious to know if I'm the only one experiencing this:
1. Battery Drain: Fully Charged at 100%, unplugged the cable at 6AM this morning. The phone has been on its battery power for roughly 7.5 hours now handling a total of 5 minutes of calls, roughly 30 text messages, 5 minutes of non-wifi internet usage, email is being pushed, and flashed 3.8. My display is set slightly below the mid section and I have zero widgets on my main screen except for the search bar. A total of 6 icons on my menu and that's it (only 1 page). My battery is at 40% right now. It's only been a day since I've had this flash and I just flashed on the 3.8 just few minutes ago.
2. From the Status Bar pull down menu, Shutdown and Reboot, Recovery option would hang and freeze the phone until I pull out the battery. I can only enter the Recovery mode manually by holding both +/- volume, power on, and releasing both once the 'samsung' logo appears.
3. Mobile HotSpot freezes for good 1-2 minutes. I cannot use my phone as a Hotspot at the moment.
I absolutely love the Nexus Rom from the looks, performance, looks to looks, but few of the glitches I've mentioned are quite irritating. If I'm the only person experiencing this, I'd want to continue on the search to remedy this issue. Please share some experience, ideas, or resolution if you have any!

1.) That's about right for battery. It's a leak so the battery life is still wanting compared to gb. If you thinks that's bad though, you should have seen uclc4
2.) Known bug. Even though its ucld2 the shutdown bug is still present for a few, and especially manifests itself as soon as you run fix permissions. Although the shutdown hang is "reportedly fixed" on ucld2 i'm running seanscreamz sky ics 4.2D-8 with ucld2 base and i have the same problem as well.
Suggestions, either use quickboot from google play, or reflash following op instructions and DO NOT fix permissions
3.) Hotspot doesn't really work all that well, even with the ultracfg fix. I recommend the "WiFi Tether 3.1-beta12" app, i'm using this instead and it works well.

Thanks for the input. I wish the battery life was better. I'll let it sink in for a few days to see if it'll improve. If not, I'll just have to keep searching for a rom with a better battery life. I've tried Beastmod, Juggnaut and many others which have yet to last for over 12 hours.
I read that the hotspot issue was fixed and with the 3.8 update, I presumed it to be completely polished. The shutdown bug, I can live with - hoping there's an upcoming fix in the works.
This ROM is the sickest looking ROM I've tried so far. I wouldn't call it the smoothest due to it's intermittent force closures and freezes, but when things improve down the road, I think this one will stay on my phone for awhile!

I've been using this rom for about a week and the battery has been working great, better than any stock rom I've had. I'll unplug it in the morning around 745 and it'll last until I go to bed around 11.

You should try Mr X' s tweaked Telus stock ROM. This ROM has the best battery life among T989 ROMs period. It is Canadian but works great on T-mobile network. It also does not have much bloatwares as T mobiles stock one. Just Make sure you have wifi sharing, wifi sharing manager and social hub frozen through titanium backup.
As for wireless hotspot, the stock one from Telus works well.
I get about 16 hours use. It may vary for you but battery lasts longest with this ROM.

A couple of issues?

- Has anybody been experiencing 3G/HSPA+ signal issues whilst on CM10-M2 or the CM10 10/14 nightly?
I completely lost my signal until I had a friend call my phone. And then it came back, but it was very slow. (The indicator was grey) This seems to happen often.
- Also, do profiles work?
I have a School profile (default lockscreen with a pattern) and a Home profile (insecure lockscreen) It seems like switching in between these does nothing since I have to still unlock the device with a pattern when I use the Home profile.
- Home button issues?
This just might be my phone, but my homebutton has not been waking my device sometimes. I have to push it extra hard for it to register.

Grey bars means you aren't connected to Google Services, I haven't had any issues with signal.
The home button is a known issue. Mine does most of the time but sometimes it takes two presses.

It could just possibly be a bad connection within the hallways (cell signal has been known to falter in there.) But even using my phone outside seems to yield a weak signal.
Okay, I thought that my home button was broken, thanks for clearing that up!
Using capacitive buttons would be some much more durable..

So, after much hassle (I managed to brick my phone) I finally managed to fix my data speeds.
Switched back to stock TW ICS.
Data speed aren't 12mbps, but at least fast enough for me to actually use my data.
Which is strange, but heck, I can finally use my phone again.
Just have to wait for the OTA Jellybean update then...

FrostyJB was the first ROM that I ever installed on my GSIII.
And I hated it....
That experience just wasn't as fast as I would like and the battery life was terrible.
I'm open to suggestions for other TW-based JB ROMS though if anyone has any.
Edit:
Even stock ICS TW doesn't suit me. Battery life is terrible (Not used at all today, screen's been on for 30 minutes = 79% battery.) and the OS itself feels groggy and slowed.
CM10 feels like the only ROM that I could really use.

For your home button, have you disabled svoice? Double press home and if svoice opens go into settings and uncheck double press home to open.
For profiles, not too sure as I've never really used them, but have you looked into apps like Tasker?
How long ago did you try the jb roms? Both Frosty and XquiziT have come a long way and according to almost everyone are great daily drivers.
For data speeds, have you tried all the different modems? My thread is now stickied in Development. Check post 3 for some build.prop tweaks that may help as well.
As for battery life, it sounds like you're just not using the correct settings if that's your goal. Turn off any features when you're not using them. Especially auto sync. If you have a poor signal this can decimate your battery. (Which may be the main cause anyway, to which id have to say to try the different modems.) I generally get great battery. Often 3-4 hours screen on and can go 20-30 hours on a charge.
Hope some of this helps.

**Edit: I got ninja-posted **
I agree on stock firmware being sluggish. It's just terrible. I personally chose to get away from TouchWiz altoghether. I don't hate the way it looks, I just like AOSP more. I've been using CM10 for over two months now.
Well, as it's been said, the home button issue has been around for a while now. Don't press it hard, just press a few times.
I don't use profiles myself. I get the feeling that the profile settings just don't encompass security settings. I would expect that to be for ringtones/volumes etc. But maybe Tasker can do this for you (PIN or slide, depending on location)? Tasker is very cool, and even more powerful. Even if it can't do this for you, it's still worth every penny (imo).
As far as your data connection, if data stops working, try cycling it off and on. It should re-establish the connection. Have you tried different modems?

I have S-Voice disabled, yes. Plus, the whole issue of the home button doesn't really bother me anymore. Simply reaching my hand up to push the powerbutton is easier now that I have switched cases.
I tried FrostyJB at the end of September.
The build.prop tweaks seem too far out of my league, but thank you so much for the modem idea!
I can remember installing the UVLI8 once upon a time and getting insane results. Will definitely give it a shot. The Jellybean modems work on JB 4.1.2 right?
My battery usage has always been the bare minimum. Literally no toggles are on (GPS, WiFi, Sync, etc) and that's my status. I've been noticing that "Cell Standby" has been the primary culprit for battery drain.

List of changes/enhancements/problems in the KitKat OTA

In the interest of making things easy for those who are holding off on the KitKat OTA, I thought it might be a good idea to consolidate all of our experiences into one thread. This is intended to cover mainly the changes specific to this OTA over Razr M-flavored Jellybean.
I'll start with my experience/thoughts and edit in additional findings. (Note: I'm bootloader locked, and now unrooted.)
The Good
The UI is definitely smoother. It doesn't jitter or stall under heavy usage anywhere near as much as it did in Jellybean.
Battery life when the phone is asleep seems to have been improved a little.
USB audio out is now supported.
The occasional "screen jitter" that plagued the Jellybean build is gone.
KitKat's Quick Settings panel is quite handy.
The native lock screen now supports adding, removing, and rearranging widgets.
Although it can't be installed from the Play Store, the Google Experience Launcher can be sideloaded and works just fine.
The Neutral / Very Subjective
The AOSP keyboard has changed; the keys are smaller and, in landscape, very squashed. You may need to adjust to it (I'm trying, but it's a struggle) or find a replacement.
Battery life when the phone is actively in use has not been noticeably improved in my experience; but it hasn't been noticeably worsened, either.
There's now a shortcut to the camera from the lock screen, which can be used even if the phone is locked by a pattern/PIN/etc. (Great if you're a shutterbug; not so great if someone else decides to troll your Dropbox/Drive account.)
The Google Camera app works - but Photosphere can't be used, as the Razr M doesn't have a gyroscope.
The Bad
No more root, for those with locked BLs (me). (Saferoot fails, and many users are reporting losing root even when they try survival methods.)
Wi-Fi tethering via most apps (e.g., FoxFi) has been blocked, so now you must pay your carrier for the feature unless a new workaround is discovered.
All notifications I've seen so far now flash the notification light white, instead of unique colors. This may be frustrating for some who used the colors to decide whether to check the phone immediately or later. (Luckily, there are ways to address this.)
The Blur launcher is same 'ol, same 'ol. It uses a solid black background for the soft keys and notifications bar (rather than taking advantage of KitKat's transparency support), and it still has that Quick Settings menu on the left (which is redundant now). In addition, Holo Launcher (which I was using) doesn't account for the space used by the softkeys at all, making it difficult to use. (I've switched to Nova Launcher, which is working fine.)
I've experienced some weirdness with the application switcher. Sometimes it drops me to the launcher right after displaying the list, and sometimes apps will overwrite another's position on the list, or be dropped from the list entirely without reason (this is always temporary, however - just bring up the switcher again).
Some apps can no longer write to the SD card - or at least not wherever they please. We still have the Files browser, mercifully (but I favor Total Commander anyway, which seems to work perfectly).
The audio quick switch on the lock screen has been removed. Also, the buttons for entering a PIN are smaller.
(Leraeniesh) Under heavy usage, the Razr M may get hotter under KitKat than it did under Jellybean, and may drain the battery more.
(GPIX) Some users have noticed decreased network performance in some apps, such as Chrome or YouTube, while on Wi-Fi and with Wi-Fi power-saving enabled.
(GPIX) Several users have reported popping noises - when a sound begins to play, or in the middle of playback. (I haven't experienced it, however.)
Swype is no longer included. If you used it in Jellybean, you will need to purchase it on the Play Store after taking the OTA.
(ls3c6) Some have encountered problems with sharing the address book to paired devices over Bluetooth.

My opinion, overall:
It's a nice upgrade, but all of little problems I've encountered (bugs, Verizon blockades, the works) make this feel like a bit of a letdown after the 6-month wait. In the end, after just three days, I find myself wishing I could take the phone back to Jellybean.
Here's hoping for either some exploitable holes or maintenance updates.

My opinion
Leraeniesh said:
So I popped my sim back into the XT907 for the weekend, and heres what I've noticed (when compared to 4.1.2).
Higher temps - previously, my XT907 hovered around 85F-100F, but with 4.4.2, I've noticed it drift toward 110F with 5+ minutes of active use.
Worse battery life - On 4.1.2 I averaged around 20% after 16 hours moderate use. With 4.4.2, I'm averaging around 5% in the same span.
Lesser LTE coverage - This may be something with my area, but I can usually get 2-3 bars of LTE in the Livingston County area on 4.1.2 (I've noticed the XT907 accel in this category). While on 4.4.2, I could not get any LTE coverage in the same area, and could only find it within more populated areas.
Slower performance - I'll always be amazed by how quick the XT907 was on 4.1.2, beating out devices with similar specs in the same price category. With 4.4.2, I've noticed frame drops, stutters, and random reboots be a common occurrence over the last few days of usage.
Overall, I'm satisfied with 4.4.2, but I still prefer the overall usability with 4.1.2.

Worth noting that I am using an unlocked bootloader, with CWM and SuperSU (only really did this to remove VZW bloat and install Xposed)

On 4.1.2 the "signal bars" were calculated by a xml in, I believe, SystemUI.apk. You could simply adjust the figures to show more or less bars, which Moto adjusted to show more. But having no LTE maybe a bad radio or a problem stemming from a bad flash. My Razr M doesn't get hot, no random reboots, and battery life seems to be the same. I haven't had any problems on KitKat.

Gonna be doing some more testing in that regard. Even my M7 with its garbage radios gets LTE just about everywhere in the Metro Detroit area.

So far my experience with 4.4.2 has been positive. I agree with OP's list and would like to add these under the issue category.
ISSUE:
Decreased WiFi effectiveness/throughput - There is a noticeable decrease in performance on apps like Youtube and Chrome web browser.
Audio Popping noises - Some experience a popping noise when the sound driver starts up while others experience it during playback.

I have had the KitKat OTA now for 2 days and haven't found anything major wrong. The changes to the keyboard bugged me but I use swiftkey so that was moot. I also have an issue I haven't seen listed yet. The new sound for screen taps....it seems to give that "popping" feedback (that ive seen listed as an issue on driver start-up) ALL the time. I maybe get 1 clear sound out of every 5-6 screen taps. That is the only real "problem" I can find as of this point though. Does anyone have any insight on that?
Also activated Dev Mode and changed to ART runtime. Might be placebo but app response seems to be noticeably better! Not groundbreaking by any means but better than 4.1.2 for sure. Overall I am happy with the upgrade. Rather, will be happy once a root exploit comes up (I miss my debloating! On that note though, disabling apps never seemed to work right with 4.1.2....after hitting disable the app would show back up in active processes after a short time. Now I've gone 24 hours and 3 phone reboots and that damn NFL app is STILL disabled and NOT running as a background process. Might just have been an issue with my phone in particular before, but its fixed now!)

I am generally happy.
It fixed all the issues I had with Dhackers KitKat.
and feels about the same once you have rid of all the Bloat.
I like and I am happy that we still surprisingly got the update unlike the Galaxy S3
Happy =)

Just wanted to comment on the heat issue mentioned above:
I have only had KitKat for 2 days but I have definitely noticed a difference in heat after extended use compared to JB. One of the things I really liked about my Razr M was lack of heat so hopefully this is a fluke and I wont notice it too much in the future.
---
With that said, no big issues.
I don't like the keyboard -seems smaller, or something, The heptic feedback seems to be different too (for the worse IMO).
The lockscreen number pad seems smaller - definitely liked the number pad from JB.
I had to change the messaging app (hated the all white/lack of contrast). Using "8sms" if anyone is curious.
I also changed launchers to use the google-now launcher so the "okay google" thing would work on the homescreen and also get the transparency notification bar. But, in doing that I did lose the circle widgets which I liked. Can't win for losing sometimes...
---
On a positive note, Chrome/google searches seem to be much faster. The UI seems about the same (no complaints with JB).
If battery life can increase then I'll be satisfied with update (so far, no difference).

My experience has been very positive. My phone was bootloader locked and not rooted before (and, of course, after) the OTA. I cleared the cache partition from the recovery menu post-install but have not done a FDR. General impressions:
-- UI is overall much snappier/quicker. Extremely noticeable.
-- Love the new quick settings panel that you can get to after pulling down the notifications shade.
-- KK's changes to how the SDcard works have not been a big deal at all for me. The native "Files" app seems to have complete read/write access, as does ES File Explorer.
-- Like the new clock feature to automatically add a "home" display when traveling outside a pre-defined timezone.
-- Hate the new way you set the alarm on the clock. (Really, whoever came up with that input method should be transferred to a department where s/he can never affect design decisions again.)
-- I miss the audio silencer/mute on the lockscreen.
-- Battery life has been interesting. When I first installed the update (morning of 05/15), battery life was definitely worse, probably by about 50%. It has gradually been getting better, however, and now is probably only about 20%-25% worse than JB. Why it would change I have no idea, but it definitely is (I've been keeping notes, and am sure it is actually happening). I have noticed, using the Battery History details screen, that there are a LOT less wakelocks in KK than JB. In JB, I used to see tons of "Awake" indicators on that screen that did not pair with "Screen On" indicators. In KK, there are very few incidences of "Awake" that are not paired with "Screen On." Someone smarter than me will have to explain how that translates into worse battery life.
-- It may be my imagination, but it seems like the battery charges faster w/ KK. If it's not my imagination, I wonder if that means that the apparent decrease in battery life is really an issue of improper calibration/accuracy.
I have not experienced some of the things others have reported:
-- No random reboots.
-- No changes to WiFi or 4G signals. I don't use Bluetooth so can't comment on that.
-- No popping noise when using audio. (Note: I have seen some reports in other forums that a FDR fixes this issue for those who have it.)

I'm on locked BL, definitly non root, and I happen to installed MotoCam from a store n IT DID INSTALLED. .
Opens up, takes pictures beautifully. .
Only problems are the slide in menu is glitchy AND after taking HDR pic, cam UI is not there. Only live cam feed.
Other than these issues, it's playing nicely ESPECIALLY auto HDR does work, surprisingly!
How can I make those problems go away??

go into wifi settings...in the setting "uncheck" the box "wi-fi optimization" it made my WiFi significantly better..

Attempted a FDR on my phone, unfortunately it did not work for me. I will attempt to clear the cache partition to see if that may help the issue if
possible. So far i can only get the boot menu for a couple seconds and im lucky to get a selection in time.
EDIT: I cleared the cache partition, no effect. (NOTE: it seems to get into the recovery menu after selecting it at boot menu, you have to hold power & vol UP for a couple seconds)

That is an excellent point. I'll shut off the optimization and will edit my results in after tinkering with it for a while.
EDIT2: Without doing speedtests etc. It is very noticable that the wifi has improved. Youtube & other apps load as fast as they did on 4.1.2

Haven't looked into it so this MIGHT be a feature of the Google Now Launcher I installed, but I JUST noticed if you swipe down from the clock area of the new lock screen, you can add widgets! Am I crazy or is this a new feature on our phones? If so, LOVE it! Helps mitigate the loss of the quicklinks from our old 4.1.2 lock screen.

Lockscreen widgets were introduced in Android 4.2.2.

Just want to let people know that the Google Now Launcher is working great on 4.4.2 including the "ok Google" functionality.
You can't download it from the play store. I just grabbed the apk from this thread.

There are many "phone info" apps in the Market. Or create the short cut with Activity Launcher.
Also the Cam sucks on my Wife's m so get the Lenovo from my Moto x signature link.
