Lose Signal when screen goes off/starting call - G2 and Desire Z Q&A, Help & Troubleshooting

Hey guys!
I'm having a tricky problem right now... i hope it's no hardware fault
I am losing my connection to my network provider as soon as the screen goes off.
I noticed it when starting a call a couple of hours ago. I had full bars and as soon as i put the phone against my ear i lost my connection --> all bars down and grey.
The weird thing is, i can call somebody no problem as long as i dont let the proximity sensor let the screen turn off. This is the same case with mobile internet. As long as the screen is on ---> no problems. Screen Off --> Signal lost
I am on an ICS Rom (AOKP build 38) and had no problems with this rom for about a week. Just changed the Rom and noticed the problem and reverted back to my backup which was supposed to still be running fine.
I even reflashed the newest radio... still losing signal
Please tell me, i'm overlooking something and this is no hardware fault from me flashing...
Any help would be greatly appreciated!
EDIT: Wow... problem solved. Flashed back to the rom that brought the problem (Elitemod). And now everything works again. Weird...

Hi. I have same problem. I flashed CM7 7.2 and it looses signal and mobile internet always when turn screen off. And it comes back right when screen turns on. WTF.. @_o. So that means at nobody canĀ“t call me. ****.

Hi,
Just check in power saver settings if you've opted for disconnecting data when screen goes off.

[Q] phone freezes when idleing

I have I really annoying problem, when I use sense roms (only sense, not AOSP) my phone freezes almost instantly when going to sleep.
This results in the phone not ringing when people call me, and first receiving texts after i reboot the phone.
And the only way to reboot it, is to remove the battery.
If anyone knows what is causing this, please let me know how to fix it, this problem have made me miss many really important calls.
Thanks in advance
i had the same problem with official 2.2 sense rom (don't know with 2.3, i switched yesterday) , but only when i was on a place with bad network.. In big town like Paris no problem, but when i moved to smallest town with bad network i experienced same freeze...
When you hit a button only the button backlight turn on?
Exactly, only the button backlight comes on.
But I have fine reception at my location
Thanks for the reply

Did you use setcpu?
Usually it happen when you use setcpu and you make screen off profile 128 mhz.

Not anymore, because I had the same idea that that could be the problem, but it still freezes
Thanks for the reply
Today it has frozen 4 times.
And every time with massive battery drains, about 15% in a short period of time.

data hanging

Hi,
Does anyone have this problem on their phone? Every now and then, when I am doing a data related function, data hangs as though it is not connected even though I am in a perfect 4g coverage area and the 4g sysmbol is still on. I know its hanging because the arrow to the right of the 4g symbol stays lit green. It either starts working 5 minutes later on its own or I turn wifi on and off. I have the newest sim card installed.
Any thoughts?
Thanks
probably a software related issue
the only time i experience that is when i lose connectivity with the network, as in the signal bars or 3G/4G arrows are all greyed
Yea dude i noticed even tho i have wifi set to never it always shuts off or i should say loses connection i hate it because i have to pull down status bar hit it off then on wifi is definitely effed on stock too. Anyone else experiencing this? I know its a problem cuz my g2x i could leave it alobe for an hour in hibernate come back and wifi still good to go anyone have any ideas? Or is it a s2 problem witg wifi cutting off. Like i said the icon will still be there but i wont have connection and 50% of the time i have wifi icon and 4g
Same issue here, in two different phones I've had. Not sure what the issue is. In fact, opening this page, my data was hanging for a minute, irony.

for this issue you can configure how WiFi behaves, but the settings are only accessible via spareparts or custom ROMs
I set my wifi to never sleep while on charger

But this happens to me when my wifi is off. Only on the cellar data connection.
I had this issue after giving juice defender superuser permissions. It seemed that it would not turn data back on when I had the screen on. I'm not sure if this applies to you, but I no longer gave juice defender su and everything was fine. a lot of those functions in that app do not seem to play nicely with this phone yet anyway.

It happens to me several times a day. Usually right after a voice call. I just put on flight mode for a second, switch it off and data is back. I have no idea what's causing this. Always on 4g, wifi is working perfectly.

+1 to everything already mentioned.
I was in Vegas this weekend and had HORRIBLY slow/no data at all. Like has been mentioned, the green arrow with just stay lit. thought i was the rom, i nandroided back to stock, same issue. Hope this is fixed soon it is hella annoying.
This fixed it for me
I have had this same issue for a while, here's how to fix it. Go to Titanium backup, I found out that there're two versions of "My account" on the list, so I frozed the old one, then go to task manager "kill all", the 4G icon will disappear. Open up "My account" again, the 4G reappears but as soon as I close the app, the 4G icon would disappear.
Hope it helps someone
I too have similar problems where my data hangs or doesnt want to connect. Then a few minutes later, it will decide to start working. This happens even in full signal regions. Stock rom and/or BeastMod rom...
Not sure why it happens :S
For those having problems and have tmobile my account on phone freeze it or uninstall it i guarantee it fixes your data problems trust me. I to had problems just like you guys and i was told to uninstall my account i was like what? What the hell is that going to do but believe me when i say it worked! I actually unfroze it to see if the problem would come back (4g and wifi on at same time) or cutting out. And it did. So i refroze my account and bam 4g disapeared while wifi on. This has fixed all my wifi and data problem phone works flawless now! Basically i think t-mobile trying to snoop with our data. Scumbags
This is happening to me. The phone is driving me mad. It happens constantly. The "up arrow" in the 4g icon will light up, and all data will freeze. I stare at loading screens all day long. It freezes anywhere from 30 seconds to 2 minutes. Then it will fix itself, then it will happen again within 2-5 minutes. I'm furious with this phone.
Wifi works great. It's not dependent on my location, it happens no matter where I am. Doesn't matter what I do, nothing prevents it from happening. Of course, the Airplane mode toggle or resetting APNs and all that will do the trick to fix it temporarily, but it will only happen again 5 minutes later.
I'm on stock, unrooted. I am ready to throw this phone at the wall. Has anybody else managed to actually fix it or get a response from Samsung/T-Mobile?
I should have read this thread before buying this phone. This is so annoying. I tried to put the phone in flight mode. It fixed for a min and back to problem.
I'm having the same problem. I didn't have this problem until I updated to 2.3.6. Anyone else still on an earlier version?

Post issues found in the ICS Leak (I927UCLG9)

its real nice to finally have some ICS goodness on my phone, but i have found some issues.
my Motorola Roadster 2 bluetooth speakerphone does not work well with this version of ICS. will not let me use the call/text button.
i am finding some apps not working correctly, i.e. Pushover - the notifications do not make a sound. Not sure if that is an app issue, or an ICS issue.
*edit* ok so it seems that i am not getting any notification sounds. sms, voicemail, etc...
also the volume in general does not seem as loud as the 2.3.6 firmware was.
anyone else find any issues?
*UPDATE* after wiping within cwmr most of my issues were no longer present. the only problem i had still was that notification sounds didnt work after a couple hours. i dont know the cause, but i used audio manager widget and set the profile to loud, and restarted phone. havent had them go out since.
I have all these issues except tue bluetooth thing

atleast it is not me.
i am going to reflash my phone to see if it may be an issue with not clearing out the phones memory and storage first...
My wifi didn't work for a while. It would see my access point but wouldn't connect. Reset the router and everything went back to normal. GPS works, Stereo BT/OBEX works, 4G works, camera works. Those were my big items, as I'm sure they are most people's.
My only issues are that I can't switch to 2g (At&t rom....) and how friggin Touch-wizzy everything is. I was expecting them to embrace the whole holo thing a lot more, but all the buttons feel like they belong in GB, same with the notification menu and the settings icons.
EDIT: I am on rogers, in case any rogers people see this so they know that everything works on our network
i wiped via cwmr and reflashed the ics rom. notifications work again. have not rooted yet, wondering if that may have been an issue with it...
Changing the lcd DPI causes the rom to corrupt i guess, since when i do it, after the reboot, i get to the samsung "logo" and then black screen, and it feels like the device has shut down. The only app that would say "success" when i change the value is Lcd Density Modder.
- i had the notification sound bug, but then i changed the notification sounds to my likings, and then i used Audio Manager widget to set the volume loud, no problems ever since.
ok rooted and all is fine. maybe i just had a bad flash. my bluetooth speakerphone still doesnt work, but that is an issue that i will have to research
For me, i had the only issue with ICS (excluding the known thing with the keyboard not flashing) - timezones from 2011 year with wrong summer times.
Luckyly fixed it with timezone fixer from google play.
Tethering doesn't work, seems to be broken and results in a blackscreen.. Both Usb and Wifi Hotspot give this issue.. Anyone else getting this
One weird thing my phone does is when it's been asleep for a while, the lockscreen clock will fall behind and when I wake it up, it'll catch up a couple dozen minutes at a time.

I've rogers version but unlocked and working with a local carrier. Wifi is not a problem at all, i'm getting the same speed and used wifi continuously for over 2 hrs to download all my apps back after the update.
When typing with the keyboard, pressing the alt. Key once makes it select all the special characters. I liked the older one where if you press it once, it operates just once when selecting the special character, and pressing it twice makes it select more than one. Not that big of an issue but to some people it may be.
Also, the brightness thing. When I turn off the screen, and turn it on again, it flashes from the highest brightness to the current.

On AT&T here, and having wifi issues as well... Once the phone drops wifi at idle, it doesn't want to pick it back up unless I turn wifi off and back on again. Setting the wifi to never sleep has been my only workaround.
Also having some issues with the button backlights. If I don't touch the phone long enough for the button backlight to turn off, touching the buttons won't turn the light back on. Touching the screen turns the backlight on again, but it's slightly annoying.
I haven't noticed any wifi issues and I use my Glide exclusively as a wifi device. I'm copying my backup of Inception v2 back right now though because the battery drain on the ICS ROM is definitely an issue. Losing like 10% an hour with my phone just sitting there with the screen off.

Have you ever took note of your battery life with a custom ROM or kernel? When I picked up my Glide it had a stock ROM but I only had it for an hour before I put a custom on it. I didn't mess with the stock one at all so I can't compare to stock 2.3.5/6. But with Inception v2/ardatdat, it was definitely better.
I was going to restore my backup but copying it back to my phone made me realize how painful it is to copy backups with CWMR 6 compared to 5. That new blobs folder makes so many files that it took 3 hours to copy 3 of my backups over USB. Ouch.
But since last night, the battery life seems to be behaving better. Its been sitting here and not just dying. I'm wondering if it could be the battery stats file. Maybe I'll try wiping it. I'm sure once we get a lower voltage kernel and I can underclock with profiles for the screen-off and stuff, it'll be fine again.
Unrelated but has anyone taken a screenshot with the ROM yet? ICS is supposed to have it built in, power button + volume down at the same time for a few seconds from what I read, but didn't seem to work.
Edit: Its home + power button at the same time.

when you flashed ICS did you wipe everything then run the ics installer? my first install sound and such didnt work, so i wiped the phone in cwmr and reflashed ics and it is better that it was on 2.3.6

Anyone else having WiFi issues on CM10 nightlies?

I have a gsm Nexus and I'm running the Aug21 nightly, but I've had this issue for awhile, at least 2 or 3 nightlies. I'm not sure how long because I was on vacation in a WiFi free zone all of last week.
My WiFi can't find any networks but can't turn off. It perpetually says 'searching for networks' but never finds any. If I try to switch it off, the switch hangs on Off with a darker shade of grey for a few seconds then flips back to On.
If I reboot the phone, everything is fine for a few hours. WiFi can turn on and off and doesn't seem to have any connection issues.
My battery life doesn't seem to be suffering all that much, so it seems that WiFi is sleeping normally.
I haven't any logs because it's hard to pinpoint the exact moment when things go wrong.
I haven't tried wiping yet, but I'll give it a try if no one has any other advice.
Is anyone else having this?

Did you figure out how to fix the problem? I'm experiencing the exact same problem.
I wound up doing a factory reset and installing CM again. If that doesn't work, format /system and wipe data before flashing. It comes back every once in awhile. I have no idea what caused it, but a reset'll fix damn near anything. I had an issue where my phone thought it was charging even when it wasn't plugged in and had to return it to get a new logic board, I might've just had a lemon. Have you had any other hardware issues?
I had this issue for a while too. After I did a full wipe and went to the latest nightly it stopped happening. Also I turned on the 'always keep wifi on during sleep' option in settings.
I get it too. It's random, and it is not fixed by changing the kernel. Very frustrating.

[Q] GPS navigation not working.

I have noticed this for the last two weeks. My GPS has been acting goofy, and if I try to navigate it will just always say "searching for GPS". I made sure that my actual gps is turned on, I did so from the drop down notification, but I noticed that when opening my maps and stuff, I don't get the gps icon in my notification bar. Any one else experiencing this? I'm wondering if my phone is jacked, or if there's s quick fix. Phone if totally stock, no Rom, it's not flashed or anything. I did update to 4.1
Thanks in advance for any help.
Reset your phone from settings> backup and restore. If that doesn't work then Odin back to stock and repeat.

Hard reset fixed this issue on my S3. Just pull the battery without shutting the phone down then turn the phone back on. I haven't had the issue come back since doing the first and only hard reset on my phone.

I have been having this same GPS issue since I upgraded to jelly bean....
I have Odin back to stock , changed my kernels, changed base bands, installed various custom ROMs and tried GPS fix apps from the playstore ...The issue still persists......The only time it worked for 2 days straight without issues was when I installed the Paranoid android AOSP ROM.....
It had various bugs I wasn't willing to live with so I am back to wicked v2.1 and still trying to find a permanent solution regarding ng the s3's GPS issue..
The GPS temporarily works when the phone is restarted but after about 10 mins the GPS icon doesn't come on again until the phone is restarted...
I am currently using my Tmobile s3 to send this message and my GPS is not functional at the moment...I always have to restart the phone when I want to use navigation..

I did a battery pull yesterday, GPS has been working along with navigation. I'm just waiting to see how long it will work now. It sounds like it's a known issue than? Let's how there's a fix!
