Develop Bugs

Just Moved over to GNEX

Hey Community! I just got a Verizon Galaxy Nexus. I am coming from the LG Revolution which was an awesome phone with great little community here in XDA.
Knowing there are about 900 pages of posts for me to read, I'm just curious if there is anything to start that I should do to make this device even more awesome? I hear volume and battery life are a general problem?
I'm looking forward to participating in this community as I get to know my phone better.....

Unlock bootloader, root, install custom rom and kernel... install volume+ if volume is an issue for you... Do you want to keep your phone stock or what?

Back in the day of the Incredible, I was a ROM Junkie. I would switch roms around every couple of days. So, no, Stock isn't necessary. From what I hear there isn't anything really spectacular with stock. I'm looking forward to trying out some of the roms and see what is the best rom/kernal/theme fix I guess.

I would flirt around with it stock and get used to ICS. Then look around for modifications you want to make and see if anyone has what you're looking for. Unlock, root, etc .
Or unlock and root now, so you don't have erase as much and be able to make a backup with root.

I think as ICS is new and interesting compared to older versions, you should first get comfortable with stock ROM, how it behave, what crashes, all in all get a good feel of the phone. Then i would suggest to tinker with custom ROMS.
Google has made a goode improvement in ICS and its worth experiencing STOCK FIRST.

I am seeing that coming to ICS from Gingerbread is like going from XP to Win 7. Functionality is still there, there are just other ways to get to it. It will take some time to get used to that's a fact.
Thanks for the responses guys. I appreciate it.

I agree, you should at least unlock and root, and then play around with stock. But eventually I'd recommend using GummyNex or Android Revolution HD if you want to feel closer to stock and AOKP or CodeNameAndroid if you want more tweaks and modifications. Then for kernels I'd recommend Faux123's kernels, LeanKernel, Trinity, and GLaDOS. I've had great battery life with Faux123 and LeanKernel, and Trinity has great speed/performance, and I've never tried GLaDOS, but I hear it's good. Anyway, try any combination of those four kernels and roms (up to 16 combos) and find the one that best suits you. For themes... I prefer the Black Exodus or Black Nexus theme, but if you want more of a colorful UI, go to the Themes section and get whatever green/blue/red/yellow etc. theme you want. =]

[Q] Custom ROM vs Stock ROM - is it really that much faster?

I bought my GSII used, already rooted, with a custom ROM already loaded on it.
I have to ask - since I never used one with a 100% pure stock ROM - is it really THAT MUCH faster with a custom?
I am currently running Juggs 5.0 - but if I went back to 100% stock would I feel that much difference?

It's not really about speed. But with a custom ROM you definitely have more customizations possible. You can change the look of the interface, the notification toggles, colors etc. I have the i9100, which is another variant of the SGS2 and I've had ICS for a couple of months now, but it's not getting officially released until this month some time. So, it's not really about speed but rather about the freedom to do other things with it. Some people might cite benchmark tests, and scream that I'm wrong, but the hardware is what makes your phone fast...the software's not at all going to choke that out (whether stock or custom). As far as speed goes, you're probably not going to notice the difference.
Also, though you've got root access which enables you to install apps and do things you just can't do otherwise.
All that said, there are certain advantages to stock. It's often times more stable than something custom. There are ups and downs. If you feel the need to experiment, you can always flash back. Just read a lot before you get your feet wet (it is very possible to brick your device if you muck it up) and you'll be fine.

I don't think so. I'm going to get flamed plenty I'm sure but I don't see much improvement over how my phone performed out of the box. I think the battery life may even have been better before I started flashing stuff.

I should have stated in my original post - I am definitely not a n00b to Android or to flashing/rooting. I can understand the customization aspect, but honestly other than flashing, I have never had a real use for Root access.
I can flash something with a new custom interface or colors and always end up coming back to something that has the stock look about it... In this case, I've tried almost every available custom ROM and keep coming back to Juggs .
I ask about speed though because all the ROM cooks seem to try to use that as a selling point... "FAST!" "Butter smooth!" blah blah blah ...

After I posted, I looked at your tag, and assumed as much with 700+ posts, you've been around the XDA block.
Really? No need for root?! I'm a flashing junkie (well, okay, that's exaggerated. it comes and goes in spurts) TitaniumBackup is my friend. Also CWM is a gift.
Agreed, stock ICS is love. But I do also like certain tweaks, i.e. the %-battery indicator (and while we're on the subject, I've got a little Android logo with a % indicator for my battery...I wonder why Android devs don't include little things like that).
Yeah, your best bet is to try some out. But IMHO devs talk too much in that regard. I'll probably get flamed if any read this, but devs are kinda like used car salesmen in that regard. They've got a product that they want you to use, so they try to sell it. Can't say I blame 'em, really. But again IMO, most of it's hype.

I didn't think you were new to Android since your account is almost 4 years old so I'd assumed you were familiar with all the "benefits" of rooting. The phone is so nice out of the box I don't think any of the roms are any smoother or better on battery. I think Warfare is probably the best on battery and for me CM7 was easliy the worst. I didn't notice a change in data speed, 2d smoothness, 3d smoothness, battery cover smoothness... Nothing. The device is so nice out of the box and I don't use it for anything other than a phone, text messaging, web browsing, e-mail, Skype, the occasional slicing of fruit or a word or two with friends so I can't comment on all the added functionality all the "super-duper heavy users" of this device probably use on custom roms. The only reason mine is rooted is for an ad host file and the occasional tether.

When I had a Fascinate... I was a huge fan of overclocking and undervolting. The same when I had a Thunderbolt. It made everything smoother and the Thunderbolt especially needed help in the battery area. This device just works. No need for anything other than what it came with for me. Obviously that didn't stop me from flashing the development section... But hey, I have a problem.

Warfare is very good.but,no advantage so far.
For me,im back on stock.just works better for me (doesnt mean I wont have a flash attack).

the thing with our device is that it came sooo sick straight out of the box that you don't really need to improve it that much. However, custom ROMs/kernels generally make the ROMs smoother, but not many people notice the difference.
I actually notice that because of the kernels implemented with certain ROMs, our phone is able to RUN just as smooth at a lower clockspeed which saves us battery. Other than that, I don't think Custom ROMs are actually "SMOOTHER" or faster than the stock ROM because Samsung really did well on this phone.

The main difference is the bloatware which really does make an impact on speed, memory consumption and overall smoothness.

Some rom cook faster, you should choose the rom cook by team have many vote on forum.

I was just going to start a similar thread actually. I have watched videos of the different ROM's that we can install on the T989 variant to get an idea of what's available and what I like. Currently SlickMOD ROM looks the smoothest with the best battery life.
Having said that, in the video that I saw, when quadrant was run on SlickMOD, while it was overclocked, the score was approx 2690. When I ran Quadrant on my Stock ROM (rooted Stock ROM without being overclocked either) I got a score of 3199. Also, after 16 hours of use I still usually have more than 50% battery life.
Other than the options for different themes and customizations and ROM control, are custom ROMs going to provide better performance and battery life than what I am already receiving with my Stock? I mean I really want to give the other ROM's a try, but the reason would be for speed and battery life and right now both are pretty good for me on Stock. Thoughts/Suggestions?

Generally speaking (I don't own this device) stock ROMs will normally get better battery life. Custom ROMs can approach stock, in this regard, but I'd be way beyond surprised if a cook made a ROM that had better battery life than Google's team of Android developers.

Problem with SlickMOD is that the dev's T989 broke and he isn't getting another one - so - development has HALTED.

Makes sense, just for fun I ran Quadrant again on my Stock Rooted ROM and got a 3358. Maybe I should reconsider switching to a different ROM for now. Stock is very stable with no real issues/concerns. thanks for the response.

It's the Stock ROM that came with my phone. I rooted the phone but haven't flashed any custom kernel's or custom ROMs on my phone. I also use Zeam Launcher as opposed to the TW Launcher by default. I have turned off animations, limited my homescreens to 3. I don't use too many widgets and I use an all black background. Also running Juice Defender to help with battery but I don't think that affects performance/speed.
Model Number = SGH-T898D
Android Version = 2.3.5
Baseband Version = T989DTLKJ3
Kernel Version = 2.6.35.11
Build Number = GINGERBREAD.TLKJ3
I don't know if that helps or answers your question. Hope that helps.

I'm willing to bet that the performance gains that are being seen on the Stock ROMs is due to the fact that they are ODEXed. By DeODEXing the ROMs can be customized to the cook's heart's content, but there is a mild performance hit taken.
Thoughts?

Setting a friend up, would like some opinions.

I am going to root and set up a friends phone most likely with aokp (I have used it on my note and it seems solid). Is this a strong choice? I am looking to give him back something with all the bells and whistles along with better performance/battery life. I guess that is somewhat redundant of me to say.
Also what kernels have you found to work well with your rom?
I also want it to be something that he does not need to maintain after I give it to him as it will likely be me updating for him until he gets comfortable with having more control of his device.

+1 for this. Stock is the best way to go (without root) if he doesn't actually know how to maintain a custom rom or know the security issues associated with rooting hour phone. If he decides in the future that he then wants more from his device, he can learn about custom roms and try flashing himself. Trust me this is the best option, I made this mistake a while ago with a friend of mine who wasn't a tech geek and all he did was complain about the issues associated with the custom rom (cm9) as he had no clue how to fix them and most of the time it was an issue with how the user operated.

AOKP is the way to go for a custom ROM in my opinion. It has so many options over stock that just help ease the use and make so much more of the device.
There is no reason why he would need to keep updating custon Roms if you put something solid on there. It is not like when he runs stock he would update it all the time. He would be running the same stock Rom for a while so what would be the difference if he runs a custom Rom for while. Why would he need to go through every build as others are saying...
Build 33 was just released for AOKP. I would wait to see the bug list before loading something on his device that will be on there for a while. Your best bet would wait till the next milestone build comes out so all the bugs will be squashed and he won't have to worry update updating...
I have also found the stock 4.0.4 kernel to be the best so far. I have tried other kernels and unless you are into playing with voltages and overclocking stock is your best bet.

As a new gnex user I found that stock kernel and rom ate battery quickly.
Coming from a nexus s 4g aokp was my top choice. So I went with that and lean kernel.
I put min/Max @ 7something/920
Using interactive
Battery life increased significantly
Also speed and my phone is fully customized to my liking... just my personal experience and opinion
sent from my so icey GalaXxy Nexus

Aokp is the way to go. Also he doesn't need to constantly update the rom. Just flash the latest milestone and he can use it for the next 2 years really.

[Q] Are the risks worth the benefits?

I got a brand new Galaxy S3 on Monday. Coming from an Inspire 4g and an HD2 before that, I'm not new to flashing ROMs or anything. I rooted that phone almost instantly, because it was a refurbished phone and didn't have a warranty. Now on this one, I'm a bit hesitant to root or flash any custom ROMs.
I've also read a bit about stock vs AOSP ROMs... can any one give me an example of each? Preferably a stable, JB based ROM? I would like to use a stock based ROM so I can have all my apps and settings back when I flash. This stock ROM is eating up battery life rather quickly so I want something quick, stable, and visually pleasing without any bloatware.
I am aware that I can just return my phone to the store within 14 days if it doesn't work... an employee told me they don't even look to see if it's rooted or has a custom ROM.

I think it is worth it. Look through the S3 forums and you'll find various options for ROMs that meet your needs. I'm running Serenity v1.1 which is a JB GNote2 port. It is stable and works well for me.
I would also read MrRobinsons stickied post about Rooting. Towards the bottom of the OP there is a tool mentioned that he made that will help you de-bloat. It works wonderfully. http://forum.xda-developers.com/showthread.php?t=1739426

I noticed it says the ATT one is " New Image Based off ATT I747UCALG1"
I have the newest software, would I be able to update after doing this? Or will that put me right back where I am now

I just put CM 10 over the stock ICE. Incredible difference. Go for it!

It really depends on what kind of user you are. If you're a user that prefers stability and is not that much of a 'power user', then the risks might be troublesome for you. If you're the user that wants adventure and doesn't mind fixing bugs every now and then, then give it a go. I'm a user that's in a middle of both - I like stability and I'm kind of a power user and I also enjoy fixing bugs because I learn something new and the experience of fixing bugs increases my knowledge of how my phone works. IMO, the most stable ROM I've used so far is CM10 - I'm currently using a nightly build and it works great so far - although it kinda has a few problems like some programs crashing unexpectedly and some phone functions not working properly. My advice is that you decide first what type of user you are and then evaluate the risks you're going to take - there's a high chance that you might brick your phone even if you've rooted a phone before as there are different specs for every phoen and one mistake could cause a serious trouble.

In my opinion, I would prefer this guide first before that: http://forum.xda-developers.com/showthread.php?t=1739426
That guide shows information that's what you're probably going to need if you don't want your phone to get out of warranty and if you want your phone's radio functioning properly. I followed that guide step-by-step and thoroughly and so far, I've achieved the desired result which is not to trip the flash counter. Also, I would also suggest that you search through the forums for revised rooting guides before you root your S3.

Here's another thought.
I came from an HD2 which from day one, I was flashing roms and kernels like crazy. I became very good at customizing and finding what I liked. I even worked very closely and aided some of the more popular rom devs. I even designed or hacked out some of my own mods including a memory management system. BUT...I could never achieve with the amazing HD2 (ahead of it' time in many ways) what the Stock Rom ICS and my S3 has done out of the box.
I meant to go to CM10 or a custom rom of some sort, but the stock rom has been a DREAM of stability which I never achieved with the HD2. It's rooted and that allows me to customize features and have more choices for apps that require root etc. I fixed a few things, added Go Launcher EX which was a huge improvement and offers awesome features, tweaked etc., and this thing runs near perfect. It's plenty fast enough. My I747m has 2gb ram and I could write a book as to why I think the 2gb makes a world of potential difference depending on setup. Also, as usual, I have frozen quite a few stock apps with Titanium Backup and replaced them with my favorite apps. (eg Handcent SMS, Kaiten Email, Boat Browser) I miss some CM features that I used to have but I have great speed, fluidity, reliability and generous flexibility....so for now...I am not doing a custom rom. FOR ME personally, I need to stay with a stable rom because I just came from near 2 years of FIXING and tweaking and killing hours upon hours.

I would be happy with just rooting it, as long as I could remove bloatware!

That's what I would do Synyster. It's great to explore, tweak, flash....etc., but if you want the best bang for the buck, best use of time, least amount of troubleshooting and testing.... imho...
- root and install custom CWM for easy flashing of updates/tweaks and for easy backup.
-buy/install Titanium Backup pro and either remove or safer....FREEZE bloatware.

There's a lot of cool things with the AOSP roms. However, I'm at the point where I've become OCD with flashing nightlies. The more I flash ROMs the more nit picky I have been. I'm looking to go back to stock firmware, debloat, root, and CWM. I think that'll be good enough for stability IMO...

I'd say so!

[Q] ROMs that enhance battery performance?

I recently bought a used Sprint Galaxy S3, it is the SPH-L710 model.
It works great, I like it, I got it rooted with no problem, and got CWM flashed to it and I'm getting ready to flash a ROM.
I've been searching forums and sites for about 2 days for the ROM I want to use.
I'm mainly looking for something that enhances my battery performance, the reason for this is when I first got the phone, I updated it to the 4.4.2 KitKat when I first turned the phone on and the battery life was terrible, like I would charge it to 100% and use it browsing the web for about 10 mins and lose sometimes upwards of 10+% within that 10 minutes.
I searched around and found 2 Apps that I am using right now, one is a battery doctor type thing, the other is an app called Battery Saver (root) it changes some stuff and is supposed to make battery life better, since I have started using these 2 apps my battery life has increased, but it still seems to drain a little fast. So I would like to try and find a ROM that perhaps has tweaked the battery life.
Does anyone have any opinions on battery life for any of the ROMs here that would work for my device, like perhaps which one that you have tried that extended your battery life? I know I could just try them myself, but I am hoping to save a bit of time and see if anyone has some input.
Also another quick question, is there a way to test my battery and see if its just bad? A friend mentioned that the battery could have just gone bad so I'd like to check that if possible.

A. S3s aren't known for their amazing battery life. My battery does not go very far either, talking on the phone, which I do a lot for work, gobbles up the battery immensely. (Like 100% to 80% in 30 minutes.) Web browsing is another battery hog.
B. ROMs are only going to do so much as far as extending your battery life. Just bear in mind -- the lighter the ROM, the less battery it'll likely consume.
You'll do more to save battery by flashing a custom kernel on top of a light ROM that'll allow you undervolt/underclock. But, you want to make sure you flash the correct kernel to the correct ROM base (e.g. Touchwiz kernel for Touchwiz ROMs, AOSP/CM based kernels for AOSP/CM based ROMs).
I personally use the DKP kernel found here in the S3 original development thread.
Be careful w/ underclocking and especially undervolting, as this can cause the phone to freeze up. It's also important to choose a governor that has a nice balance between performance and power savings. (I like the freelunch governor.)
Hope this helps.

I personally use the DKP kernel found here in the S3 original development thread.
Be careful w/ underclocking and especially undervolting, as this can cause the phone to freeze up. It's also important to choose a governor that has a nice balance between performance and power savings. (I like the freelunch governor.)
Hope this helps.

Thanks!
That gives me an idea of what I should start looking for, and I'll check out the DKP kernel as well..
I just thought of another question I had, maybe you can help me with it too.
Since I'm running Android 4.4.2 on my device, would I need to find a 4.4.2 ROM to flash?
For instance could I use a 4.3.1 ROM on my 4.4.2 device?

It doesn't matter which Android version you decide to go with. Just avoid two things:
1. Do not flash an older bootloader than the one you are currently on (e.g. If you are currently on ND8, do not flash any older bootloaders like MK5 or MD4).
2. Do not flash any modems older than the one you're currently on. Your modem version can be found in Settings -->About Phone --> and the last three letter/number combination under "Baseband Version". Hint: The baseband version also tells you which bootloader/ROM you're on.
Doing either of these, will trip Samsung's KNOX security feature, tripping the kill-fuse, and suddenly, you'll have yourself a nice hard brick.
I know that probably sounds intimidating, but I assure you if you avoid those two things, you can flash any D2LTE ROM you please. (D2LTE ROMs will work with the Sprint S3.)

idk man the batter life of my S3 lasts 2 days where my Infuse 4g would last less then one with a new battery.....so by far the best battery life I've had in a while

Wew! Thanks for that info, you may have saved me from a terrible mistake lol.
One of the ROMs I was looking at was using the MD4 bootloader, so that would have been a no-no xD
Thanks a lot for all your help, I learned a few things from it, epspecially about the bootloaders and modems having to match, I had no idea about that. Now that I know that, it opens up a few more possibilities for ROMs I can use!

Fun fact: The bootloaders and modems didn't always have to match.
Samsung wanted to be able to market their devices to business entities, and in order to do that, they developed the KNOX security feature.
Once it's on your phone, it's not coming off. It matters to corporate security policy people, because they want devices that aren't going to be compromised if someone tampers with them.
And, as you can see, the wrong kind of tampering makes the phone completely unusable and unrecoverable.

Right now I'm sort of leaning towards LiquidSmooth, Quantam4, or Tribute ROM, still sort of looking around though.
If you don't mind me asking @Higgs_Boson, which ROM are you using?
Also, to the other poster, my mothers GS3 is the same way, hers will last upwards of a day and a half, then again she doesn;t use hers for much, while I'm on mine like a computer lol.

Right now, I'm on CM11.
I usually switch between two that are my favorites:
CyanogenMod or Paranoid Android.
If you want an all-in-one, there is always PAC-ROM, which includes Paranoid Android, AOKP, and CM all under the same roof. (But then, we get back to that thing about light ROMs.)

I completely overlooked CM
Is CM11 compatible with the DKP Kernel you were telling me about?

yep
Yes it is. I'm that combo at the moment

im currently running wicked X 8.0

personally yes after i replace the system UI with the Stock ND8/NDC one and same with the TW Framework and TWframework-res.apk and use the Stockish theme for it.....i like the stock look what can i say but im using xposed at the same time for little things here and there but if you don't want to replace somethings and want it to work 100% use the PCB theme that it comes with.......but either way its pretty smooth and fast and the battery lasts for 2 days with some gaming and listening to music with viper4android installed and making calls and texting the one thing that i would say drains my battery is watching videos but you'll be satisfied

Wow you arent joking. This is one of the best ive seen lately. Nice.

Wicked X, Tribute and Conquest Singularity are all 3 very good ROMs with pretty fair battery life. As stated, Kernal Settings do make a world of difference! I'm on Singularity with latest KT747 Kernal and love it :]

Cm 11 or paranoid
