3G Periodically Shuts Off - Sprint Samsung Galaxy S III

Have Cyanogen Mod installed, constantly have 4 bars of 3G data in Brooklyn, NY.
Whenever I'm using the phone in hand, the data shuts off every 10 to 45 minutes. The only way to bring it back on reliably is to go into the settings, turn off data, put it into airplane mode, wait a few seconds, then turn it back to normal mode.
There's no "data" toggle on the top-screen slide-down applet, so this is kind of a pain in the ass to do every single time this happens.
Has anyone else experienced this and/or solved it?

I have had this on my EVO, and it may just be the ROM. I have not ran CM b/c the other ROM's that are based off CM have more features like a notification toggle for data, which would help you.
I recommend doing a full wipe and re-install of the ROM. You can use Titanium Backup to save everything and restore everything. It should be like nothing changed, and hopefully it fixes that bug. If not, maybe resort do a different version of CM or ROm altogether.
Best of luck with this, it is annoying, but not the worst problem you can get (on the bright side).

Yeah, I have that issue too, but I switched to blackbean5 ROM, and I dont see it that often now, also I am running a KTOONEZ kernel, I dont know bout you but my sprint reception here in bklyn is awful.

Its still in the nightly stage and has this, as well as plenty of other problems but they are getting fixed so give it time and try the newest nightlys

[Updated 3/13/12] FC07 Issue Log

It seems like we are almost close to see the public ICS version. FC07 is also one of the best ROM that we've seen so far and many issues from the previous version are already fixed on FC07.
But, I still see many peoples are complaining about the issues on FC07 from here and there. So, it would be great if we can see all real or possible issues in one place. This is the reason why I'm starting this thread.
Because I started, I want to add one :
Occasionally, GPS lock notification is not disappeared even the GPS turned off and there's no app using it.
Story - After flashing FC07 from FC06, I was checking individual apps and opened Go Weather app. Go Weather app asked be to enable My Location, so I did. Go Weather asked me 'GPS module is diabled. do you want to go to GPS settings?', so I turned on GPS and came back to Go Weather. It started searching and locked the GPS. After that, GPS notification always showed even I closed the App.
Just like happened in FC06, after the reboot, I do not see the same problem any more. Fortunately, I kept the screenshot of it.
[Update]
Now my FC07 ROM works much better than any of previous ROMs - sreenshots available in this post and post #50.
First, how stupid I was!
Late last night, I disabled the Battery saver script - Juice defender - and after that my Stock (rooted) FC07 ROM started working flawlessly. Even the battery life is showing great. After unplugged, it only used 10% for two hours.
Only one problem that I saw was GPS lock notification. It was there even I turned off everything. As we mentioned many times, only the workaround for this is just rebooting the phone.
Since last night, I do not see any apps FC'd. GPS working great, my wifi status is always updated even after the sleep.
So, if you see some weird issue on your ICS Rom, make sure you test your phone with any battery saver application. What I did during last night was, disabled Juice Defender and disabled some startups which I really don't need. One more thing I did was, configured CPU thru System Tuner Pro to use the ondemand govener. That's it and I'm happy with this FC07 ROM.
(Before this change, I also made the GPS tuneup on post #47, it's still effective on my phone and working great)
Right now, my phone stays cool without any issues.
(ps I updated Google map in this morning. I think this updated app is much better than previous version)
[Update]
I hope this would be the last update before I jump into coming FC13.
This afternoon, after a sleep mode, wifi did not show the signal bar again. But at this time, just turning off and on worked. Wifi signal came back to normal (don't need to reboot).
* Adding two more screenshots showing excellent battery life on FC07*

The gps disconnects frequently. It does connect fast but cannot hold a signal and when it does lose signal you have to reset the phone to be able to reconnect again. Also they have not fixed the issues with the media scanner. It still messes up the camera app a work around to open a 3rd party camera app and restart the phone this fixes this issue.

The gps lock notification does disappear with the EL29 modem. So maybe the problem is with the modem and not the Rom. Also Copilot 9 works with the EL29 modem and this Rom with no problems because the gps lock notification disappears when it is not in use.

Had GPS on for awhile when I ran FC07 (with the modem) never had the icon stay when I turned it off it went away like it should. Some people are having the issue however so not really sure it's with the modem.
I agree with GPS sticking around even after closing sometimes, which drains battery and warms the phone.
Other then GPS issues this has been a solid phone made better with the ICS roms
Thanks for starting this thread since I believe Samsung is monitoring this forum.

No system wide font size from what I hear. Can we call that an "issue"? =P
Has anyone gone in and taken a look at the build.prop "settings" for wifi?
Sometimes it happens that the wifi.suppplicant_scan_interval on roms based on these stock leaks we get is set as high as like 240..THAT is one thing that could definitely be lowered to like 90, and the lock would be much faster...
(I can't check it myself right now, because my ET4G is in transit due to a hard-brick replacement.)
It's definitely something someone might wanna take a look at.)

Mine shows 15 and I never touched this option. So, I believe it would be the stock default.
For me, the main thing that has been fixed is stability...but then again the leaks are coming way to fast to truly test stability (aka running for over a week). My two biggest gripes with the ics leaked roms hasn't been fixed since the early leaks...notification sounds sometimes still disappearing, and the gps bug still exists (albeit less frequently).

15?
I can't say I've ever seen that value placed so low in ANY rom on any phone....90 is usually the go-to 'custom' setting most "chefs" will use...15 doesn't seem like it would give the wifi even enough time to establish a connection before it went in to re-scan mode.
Hm.

To save the battery, I see many places are recommending '90' but anyway, FC07's stock value is '15'.
15 is the same on the GB rooms too.

Don't expect GPS fix.
Samsung engineers can't write GPS drivers to save their own lives. Pretty much every Samsung phone have had serious GPS issues.
HTC GPS = Godmode. Samsung GPS = Failmode.

LOL. Mine literally just got a lock on me (and on the correct side of the house) in about 4 seconds.
Well, most of this thread has been about GPS, but I'll throw my hat into the ring with something different.
I still can't get Bluetooth to pair with my Sony car stereo, and while I can pair with my Infinity car system, trying to play any audio causes Bluetooth to force close. It works fine in both cars on the GB ROM so this is certainly a ICS build issue. Although not necessarily only on FC07. It hasn't worked on any of the builds.

I am glad you are checking the Bluetooth car connectivity. I am checking the leaks with my stereo headphones and my regular Bluetooth but that's good you caught that car connection issue. It seems like there aren't many people checking the Bluetooth side of these leaks

Roam control issues

Does anyone else have issues with I in ics
What issue?
I've used it with almost all AOSP ROMs. they trick I have found is to make the selection Automatic or Roam Only. Then once its past the super user prompt I reboot the phone. Once its booted back up it works perfect. If you choose the option in the app to reboot after selection it won't work. It reboots it too quick so the selection doesn't stick.
or make sure u bought it and have latest version.. it takes time.. i have it set to exit application after selection and dont have any issues
Sent from my SPH-D710 using XDA
It is a little wonky sometimes... like it takes longer than usual to make the change or it flips back a forth a few times when I put it back to automatic from roam only. It also seems to be rom dependent. Under Blu Kuban, it seems to be flawless. Under Agats and Ice it seems laggy and under m'ics it did that back and forth thing. You might be seeing something completely different though. What exactly are your issues?

[Q] Don't know what to do anymore...

Hello Everyone,
Problem: Set up a word password for the lock screen, forgot the password, entered as many times what I could try to remember, couldn't remember it at all, forgot password option never appeared. Had data on sdcard so didn't care if I'm going to hard reset the phone.
From CWM Recovery 6.0.1.2 did the following ( a lot of times ) : wipe data/factory reset , wipe cache partition , format /system, format /cache, format /data, format /sdcard, format /external_sd as well ( different card ). Rebooted. Everything seemed normal, initial setup, google account, date/time, location/gps. browsing through the phone until the 30seconds backlight timeout passed and screen went off. I press unlock/power button and viola, password prompt back again. WTF ? I DID everything.. did the same thing again, this time, after the initial setup, did samsung's code *2767*3855#, started automatically doing factory reset. again after this, initial setup and still password prompt. did this again, went into settings and change screen lock, and it said to enter password. Seeing that's not helping, downloaded a stock rom, and flashed it through odin 4.43. everything seemed good until again went to screen lock settings and same thing. after screen went black, the same thing.
rooted again, installed cwm, flashed custom rom bagux-project-rom-v1.4, seemed good until went to settings and prompt there as well as screen went black turned it on and prompt again.
gbsIII rom - same problem
cow rom - same problem
ehndroix 12.9.13 - same problem
f.a.w. ris4 - same problem all these roms based on 2.3.6/2.3.7
flashed ancora_signed(cyanogenmod) - NO PROBLEM
flashed cm-9 experimental - NO PROBLEM
flashed RemICS_1.7 - NO PROBLEM
Problem is that I really want ENERGY SAVING OPTIONS because that way the battery lasted me two full days on normal/median usage, texting calling wifi and 3G. ICS DO NOT HAVE THIS AND therefore my battery on the same type of activity lasts not even a day.
ALSO, Somehow, wifi drastically downgraded it's performance meaning it takes really long to turn on, sometimes scans sometimes doesn't, when there is 100% a signal in one spot, it won't find it at all, and other time it will and the worse part is that when it connects, and connection is, ip and everything good, internet doesn't work. < this only on ICS or cyanogenmod. < but this is not what I'm concerned about. Just saying if It might help.
I don't know what to do anymore... I'm not a noob at this because I have rooted MYSELF and flashed roms and other stuff to Samsung Gio Samsung Galaxy S II and Htc Desire-Z (a7272) and now I have my wonder I8150 and this is just SHOCKING TO ME. I really did not expect something like this...
it looks like something easy to fix however on the other side..i don't know.. maybe I am not doing an extra step ?
Please, I really need assistance..
So let me get this straight. You couldn't get rid of your lockscreen in any GB rom, then decided to flash an ICS rom and it worked but you want to save battery. Then you discovered the wifi problem and you don't know what to do. Right?

So because you didn't reply as fast as i thought, i will just answer what i understood.
1-about your lockscreen problem, this is might be because of a restore you previously set to automatic. I actually don't have any other reason cuz this just never happened to me or ever heard of it.
2- And about the power saving you want to have in ICS. I have tried that build-in power saver, it doesn't work as well as some other power savers from the playstore.
Adding to (2) i don't use any power saver cuz they just turn down your phone's speed to save battery. I use setcpu (app from playstore) to create different profiles that work in different times (like when screen is off speed goes down as i don't need it and when screen is on speed comes back up).
3- The wifi problem you only noticed in ICS because its a bug in arco's kernel which almost every JB/ICS kernel is based on, but don't worry arco will soon find a cure. But until then, when this happens just long press the wifi icon in the statusbar and it will open the wifi settings, which will start an automatic search and connect from there.

Hey &Amada
Thanks for replying and to my response time, I just got home, lol..
The problem I have is with the lockscreen (password prompt). if I flash a stock or custom gb rom, the lockscreen ( password prompt )turns on after the screen turns black ( after 30 seconds ) and returning to the "restore / backup , I didn't set it all, it was already ticked, the automatic part, on every gb rom too and worse was I couldn't untick it...
Right now I have ICS ancora beta 3 and there is a "performance" tab in settings before "about phone" and in thereis processor - change cpu governor and clock speed and types like consevative ondemand performance interactive powersave and minimum cpu frequency and max and set on boot. If setting a lower clock when screen is off would improve my battery or at least I would notice it then I would go for it but here's a great example. right now, on ics, when i take out the usb charger cable from phone, the second i take it out, 100% drops to 99%. in gb rom, stayed on 100% for about 30minutes minimum. just comparing. and this is on the same usage.
I went to a service guy, which my friend from school knows and recommendem I'm 18 btw and in high school as well and he said it might be faulty cache ( the memory part ) because it's similar to people's dead sdcards in phones and password prompts appear for them and the phone interprets it as a security exploit or break and therefore takes it as a password prompt.
& to the wifi, it's not a big problem, but it is annoying.

Okay, maybe you could go back to gb or JB i am using pacman and it rocks i didn't face the wifi problem since flashed.
But if you really want to go back to gb here is my suggestion:
You said that after you flashed gb with sometime, the lockscreen comes back. So just as soon as you reboot from flashing just install a lock screen replacement from the market or such. And make sure they can be toggled in the accessibility section of the settings. That way it will automatically disable the lockscreen even if it comes back

Hey, I tried "MyLock utilities" but it did not work.. apps aren't an answer to keep bypassing the screen lock all the time.. I don't get why the phone "remembers" the password even though it's formatted... faulty memory ?

[Q] Wifi Dropping on AOSP/CM ROMs

I've done loads of searching here, heard about the *#0011# and switching Power Saving mode off, which doesn't apply to AOSP/CM based ROMs, and tons of beating my head against the wall for the past few weeks. I have "keep WiFi awake when screen off" set to "Always." I tried setting my frequency to both 2.4ghz and 5ghz only with no luck. I have tried the stock CM kernel, ktoonsez's Kernel, Lean Kernel with none of them changing anything. I have tried an array of ROMs, including CM10 stable, CM10 nightlies, Task's AOKP, Slim, LiquidSmooth, ... the list goes on.
Long story short: my WiFi will occasionally drop connection to the network and not come back up until I turn off and turn on the WiFi again. If it drops and I go into the list of signals I get, it seems to pick up the network and have decent strength, but it will not reconnect and just says "Saved" underneath the record. How long it takes before it drops ranges anywhere from a few hours to a few seconds. It does seem to happen more often than not with low signals to the router, but I've been in the same room as a router with full bars and it will still happen. I've tried different routers, different router configurations, and different networks entirely, same deal. It does not affect my cell data, just my WiFi.
I am currently trying a stock ROM to see if it happens on stock, and so far it has not occurred. I have done full wipes of all data and clean installing a new ROM, I have tried installing stock and then dirty installing to a new ROM. Nothing seems to solve the problem. I ran a logcat when the problem occurred (lost the log, sorry) and the entry from wpa_supplicant was "AP scan failed". I am at my wits end here. Has anyone had the same problem and found a solution? None of the solutions I've found so far have seemed to work.
Edit:
Stock ROM seemed to have stable WiFi.
Completely formatted phone back to virgin stock, rerooted, installed CWM instead of TWRP (really don't think this would have a difference), factory reset, wiped data, wiped system AGAIN, wiped cache, wiped davlik, installed Task650's AOKP. WiFi seems stable again. Maybe his kernel? Maybe something during wipe? Maybe CWM vs TWRP (unlikely)? I'm unsure if the problem is even solved, honestly, but so far it seems stable. Will keep this updated. I'm going to start installing apps (not from Titanium backup this time) one at a time...

WiFi seems stable again. Maybe his kernel? Maybe something during wipe? Maybe CWM vs TWRP (unlikely)? I'm unsure if the problem is even solved, honestly, but so far it seems stable. Will keep this updated. I'm going to start installing apps (not from Titanium backup this time) one at a time...

I've had the same issue with all AOSP based roms. There seems to be an issue with cm 10 which is the base for all AOSP and aokp roms. The touch wiz roms I've tried have no issues and you can go into settings and disable wifi sleep with them.

That's a shame, but I suppose at least I'm not an isolated case. I didn't figure I was considering I could find other people posting about it, but all the posts seem old and never got much attention. So far task650's AOKP seems fairly stable. I haven't had it drop out on me at home yet, though the WiFi does seem to have difficulty coming up after a boot. I suppose worst case scenario I could switch to a TW ROM, but I really like the AOSP experience better :\ (minus TW's camera)

In addition to having wifi issues I found all the AOSP/AOKP based roms to have screen wake issues. The camera on non touch wiz based roms is also considerably slower. For now I'm sticking with the stock virgin rom - rooted with toggle mod installed. Wifi on the AOSP/AOKP based roms seems to disable when I go to bed. Then I have disable and enable for it to reconnect. I've tried 10+ roms still haven't found that was stable with the features I want. The only I didn't try was flashing a new kernel. Maybe that will solve both the wifi and screen wake issues. I would rather the rom be stable than have tons of features and being buggy.

If you are interested in running an AOSP/AOKP ROM still, give Task650's AOKP a try. After a fresh wipe, to virgin stock, to rooted stock, wipe, and then to his ROM, it seems stable. I haven't had a WiFi drop for about 24 hrs, and it seems stable. I did have some WiFi problems on the first boot or two (WiFi wouldn't be on at boot and a tad stubborn to come on, stable after it came on), but that seems to have solved itself now... I say seem though, because like I said in my OP it can sometimes take hours to drop WiFi. He does use a kernel that isn't the CM10 kernel, so maybe that has something to do with it?
I'm loading my apps back on in waves to try and see if maybe it's an app. So far it's still stable.. I'm about to start downloading all my Spotify playlists which it typically would **** out on, so we'll see. If it starts again I'll be going back to stock.

I did give that rom a try. I had the same wifi issue when I went to bed. It also happens after the phone is rebooted. In addition I was getting the screen wake issue. Task's rom is still based on cm 10 so will have the same bugs. Maybe changing the kernel to task's own kernel or the other AOSP kernel. I'll give a try one of these days. Let me know how that works out for you.
Do you guys having this problem have "Avoid poor connections" checked in the Wifi advanced settings? I don't remember if CM10 has this, but AOKP does. I expected that this setting would cause the phone to switch to a better AP if the signal was low but it seems like it just stops Wifi data completely. After disabling this setting I haven't had any issues.
I've been running CM10 nightlies with the CM10 kernel since late November and haven't had any issues with WiFi. I am on my 2nd GS3, first one returned due to phone speaker (not the speakerphone on the back) and on that one my WiFi was sketchy. Not sure if it was a hardware problem, or CM10 merged a fix close to when I swapped out devices. Either way, I use the latest twrp recovery flashed from GooManager and Formula84 10/12 Gapps. I update daily with the CM Updater, and haven't had any issues other than what is already reported to be a bug on CM (which in all reality is, nothing, since I NEVER use Bluetooth)

I'm only asking for reference, this happened to me somewhat on CM10, and my roommate on his Stock GS3. Anyone with these issues using a Netgear router? We dumped ours for an Asus and haven't seen a problem since. I hate netgear so much...

Avoid poor connections is always unchecked for me. I also make sure wifi is set to never sleep.

I'm using the linksys e4200v2 router. Never had any issues with any of my devices except after I flash AOSP/AOKP based roms. I have 8 devices connected wirelessly with no issues.
My router at home is a Netgear. Not sure about work. The weird part for me is that I didn't use to have these problems with AOSP ROMs, not that I remember anyways. It seems like a recent development in the past few weeks.
Still having decent luck with task650's ROM. It did happen to me once last night at home but it's been stable as a rock otherwise. If it starts happening more I'm gonna flash stock. If it continues to happen from there I'll consider it a hardware defect and go ***** to AT&T.

I just tried two roms (liquid smooth and tasks aokp). Had wifi issues with both of them after reboot. I decided to try two custom kernels (underwear and ktoonsez). Still experienced wifi saying not in range. The issue seems to be with the latest cm base which is used in all AOSP and AOKP roms. I hope this issue is fixed with the new cm 10.1 base. I guess I'll be stuck using only touch wiz roms now.
Found a great app that solves the wifi issue. It's called smart wifi toggler. Wifi reconnects after reboot now and remains connected when I go to sleep.

It sounds like something is going wrong when you flashed the ROM. Task's AOKP isn't CM based (he cherry-picks from it, but builds from source), and I've never had a Wi-Fi issue with it.

Thanks for the heads up! I still have been having good luck with task650's ROM, but I will try this out on other ROMs!

I've been having good luck as well with tasks, but I don't know what could be going wrong when flashing a CM based ROM that is so consistent, unless it's either a hardware issue or something in their code base.

No prob. I'm finally able to enjoy tasks aokp now that I got the wifi issue solved with using smart wifi toggler. It's a great rom, with tons of features and customizations.

random freezes

I'm sure this may have been covered, but I'm really getting tired of having to pull the battery every time. My poor back cover is losing its hooks from doing it up to 3 times a day. So far, it hasn't been a certain app or action that causes it, it seems quite random. It will just completely freeze with no button presses, only thing to do is pull the battery. I've used multiple different ROMs, but it seems to happen on every one. Is this just something I'll have to deal with or is there any kind of fix?
Weel, to avoid the back cover damaging it's better (if you have a PC next to you) that you reboot through adb reboot instead pulling the battery...
For better understanding your problem you've to tell which rom are you using, which kernel, how did you install it (clean or dirty flash), have you restored setting with TiBu or other apps, and last but not least if you're configuring your phone with some strange settings (i.e. overclock, undervolt, tweaked build.prop and so on).
Currently, I'm running jbsourcery 4.3 with zen kernel 16 with it set on pegasusq and sio, no other over clock or under volt settings. I've tried comotio, atom, factoryrom, cleanrom, paranoid, and I can't remember what else. I've also tried trinity, air, and Franco kernels. Every time I flash something new, I do a full wipe, cache, dalvik, factory reset, and format system. I usually use ROM toolbox pro to restore apps and settings as opposed to tibu, but the last time I let Google restore the apps, then restored data to the ones I needed.
I'd return to stock (Google factory images) for a couple of days to test if the random freezes stop.
I have had a similar experience to yours. I have noticed the nearest thing to a common theme is it usually seems to happen when going from WiFi to 4g or 3g and sometimes from a 3g signal to a 4g signal (or the other way around). It also happens immediately when trying to turn off airplane mode. It is very frustrating. The experience has been minimized since going to mmuzzy's room and tiny's kernel. On that setup, I haven't had to do a battery pull in a little over a week. I am guessing it is because mmuzzy's room is much closer to source. You might give it a try.

Should be mmuzzy's ROM. Spell check not always helpful!

I went ahead and took your advice and ran bone stock for a couple days. It was good the first day, the second day the freezes started again. I went ahead and flashed one of the stable AOKP builds with zen kernel and it still freezes. I just downloaded the team lean AOKP and am gonna try that next, but its just so frustrating!

Tiny4579 (developer of the Tiny kernel), just reported that this is a known issue with the stock kernel and that until Google fixes the issue there is nothing any developer can do to fix it. While it doesn't fix the problem, it helps me to know that. BTW, I have had the fewest with Tiny kernel of any I have tried.

Nothing like that here, tested for long enough with stock, custom built aosp and CyanogenMod.
Are you sure it ain't the app data you're restoring?...
When we say go back to stock to test, you need to run stock with the bare minimum and not restoring anything. I.e To test, I run stock with 2 extra apps: a file manager and supersu, for over a week.
