G2 randomly losing data signal... - G2 Q&A, Help & Troubleshooting

Hi all,
Got a bit of a strange one and whilst I don't normally ask for help on here I am at a loss on what to do to fix the issue I am having.
My LG G2 seems to be dropping it's data connection, and struggling to reconnect. It is usually happening when I have low signal and even when I am back up to full signal (and have waited a decent amount of time) it will not reconnect. The only way to fix it is a reboot of the handset.
It has done this on two different roms so don't think it is rom related, and have tried reinstalling the baseband... With no success.
Anyone have any ideas what could be causing this and what else I could try?

Are you on EE? Me and my friend noticed the 3g network has been flaky the last few weeks.

Orange... So basically the same thing yeah.
To be honest I did think it was strange as it started quite randomly and not when switching Rom etc. Fingers crossed it's just a temporary issue with the network then. Thanks for posting!

I have a similar issue. Losing cellular connection in its entirety. Rebooting seems to be the only fix. I'm certain it's a hardware issue.

G2 randomly reboots

My phone keeps on randomly rebooting. Is anyone having the same problem?
Sent from my T-Mobile G2 using XDA App
I am experiencing this problem too.
It rebooted once when I was using the Camera (Youtube HD Video mode)
Once When Trying to open Gallery.
And once while just sitting here on my desk at work.
I want to love this phone so bad! I really like it so far though, and the keyboard issue is def. not a problem for me, and I think it's probably a design flaw rather than a manufacturing "defect" considering there are no springs. It is very hard to recreate the hinge problem while holding it naturally, including at a 45 degree angle in bed.
I also have had a few reboots and also media server force closes while running other apps. Never had these issues with my N1. Luckily I still have it. I'll give it a few more days and probably end up returning this G2 and going back to the N1.

I have been waiting for a good QWERTY phone with a fast CPU and a WVGA, passed on the nexus one and kept my G1. After running CM6 on my G1 (usable but sloooow) there is no going back for me after using the G2.
I sure hope this is something fixable in a firmware update
Does it reboot all the way to the white htc screen or the grey tmo g2 screen? Mine does it to the tmo screen and seems to only happen when the phone has been sitting for awhile and I pass through an area with no reception and when I hit reception again is when it happens. Almost like its turning itself off but stays on enough to look for signal and then turns back on. I only say this because on my drive I know the spots where I lose service and the phone does the reboot in those spots. Anyone else?

Yea I had this happen today when roaming in nw ohio I think it may have started after taking pics of my niece. I also have a problem with the memory card it says it mounted read only and none of my pics or anything show up in the gallery.
The incredible used to randomly reboot. I believe that was due to when there was low signal. It was fixed with an ota.

It goes to the G2 logo screen.
I have also had two occurrences of it being stuck at that screen and the power button not responding to long press or anything, only solution was to remove battery.

That would make a lot of sense, I'm at work right now and my signal is very weak here, goes in and out all the time.
What about others who are experiencing this problem?
Also, I am using a Class 6 A-Data 8gb microsd partitioned for ext3/swap/fat (not the included card), and so far each time it has rebooted the USB cable was plugged into a PC (for charging only, no debug or mass storage)
I wonder if any of this matches up with others who are having issues?
Mines always happened not plugged in and has never gotten stuck.

g2 reboot and mulitple force closes
i am getting the reboot issue also, it seems to be random when i am opening an app or going in to basically anything. also i am getting multiple force closes in basically all apps. i did a master reset and going to reload all apps and such and see if that fixes anything.
Could be something you have installed too I remember some people having this problem when nexus first came out and they built a list and narrowed it down
Sent from my T-Mobile G2 using XDA App
There's a thread on Tmo forums about this issue, the guy fixed it by transferring his number to the new sim card that came with the phone. If you haven't tried it, give it a try.
I updated my sim and haven't had any reboots yet
Sent from my T-Mobile G2 using XDA App
For what its worth, my N1 reboots occasionally, randomly when I may be doing something. Happening ever since I got it. Maybe sone kind of exception happening in Android?
Sent from my Nexus One using XDA App
I have transferred my sim also and am still having this problem. It was after going through a no signal zone, which sucks because I am in hotels and places where I have no signal all the time.

Thanks for this tidbit. I called Tech Support and had my phone number moved to the SIM that came with the phone. Probably a long-shot, but what the hell...
Well, after 2 hours on a fresh charge, I sat my phone down for 15 minutes. When I picked it up it was dead (black screen). Had to pull the battery.
Seemed to be a weird fluke. Did have another reboot, though it felt Android related versus hardware.

So it rebooted on me this morning in a spot with perfect reception. I was trying to open the xda app but it wasn't opening...almost like I didn't have any data. Fishy fishy..
Sent from my T-Mobile G2 using XDA App
Mine actually rebooted twice on me, both at random times.
1st occurence - I was listening to pandora, skipped a song while the loading circle was going on, I tried to go back to the home screen and it did take me there but than rebooted all of a sudden - It went straight to the G2 gray screen with the T-mo logo
2nd occurence - again I was listening to iheartradio app, trying to switch to a different but it rebooted back to the t-mobile gray screen ----- i think iheartradio is not tailored for android 2.2 yet, so i thought it could be the culprit.. since it only supports upto 2.1 in the market.
but yea nothing else as of now... hopefully it wont happen again.
This happened to me for the first time today. I was on the web, pressed the home button and scrolled thru the screens to get to my widget and it froze on me and rebooted to the t-mo g2 launch screen.. it actually stayed there for a good 2 mins so I pulled the battery and rebooted after and it was fine.. is this an on going problem that'll be fixed soon? i hope?

G2 radio issues......

How wide spread are these issues. I'm on my 3rd phone now and a side from an annoying dead pixel my phone still fades in and out while on voice calls to the point where I can't even catch a full conversation sometimes. Also drops calls.
The OTA did not help the problem one bit.
Is this something that will be/could be fine tuned? I've read the nexus never had a good radio compared to "other" phones.
As much as I like this g2 I can't have the poor voice quality issues.
Sent from my T-Mobile G2 using XDA App
For me, the radio got a tad better after the ota. I still get **** reception at home, but now it seems like it doesn't drop signal like before, but then again, I just installed the ota and rooted last night on the stock rom.
Sent from my T-Mobile G2 using XDA App
I got lucky the first time through, my hinge was pretty tight, i had 3.2 gb free space in my phone, and had one one minor antenna issue. Once a week or so I would drive somewhere and when I would look at my phone i would have an X and no bars. Only way to fix it was to restart, since it only happened once a week i didnt really bother with it. The OTA Fixed that problem so im just very lucky this phone around
ps: jk about the 3.2 gb, i got around 1.3 gb like everyone else
I am still seeing radio issues after the OTA. By switching it to airplane mode, then back to non-airplane mode (versus a rdeboot), the issue is temporarily resolved. Makes me think its a s/w issue with the radio. During the initial release I had to reboot to get a lock on GPS (a few times).
Hoping cell reception gets fixed in an upcoming OTA. Sucks having worst reception than my G1. Until then, wifi calling is saving the day at my house.
The only thing we can do is keep complaining and hope they listen.

Sounds like it might not be a specific phone issue.
I really want to keep this phone but the radio is unacceptable! My wife's BB gets 3g throughout the house, and not only that she can talk on it without issues....

Same with me for the most part. I just did the airplane mode trick, and it's the first time I've had to since the OTA. I have had the data drop plenty of times since the OTA, but after a few seconds it would come back again. The OTA was supposed to address this radio recovery problem, but clearly it didn't fix everything. I think I'm going to call customer service again and let them know.
On a side note I believe the issue I had today was with the XP tether driver. I think it's rather buggy as it tends to get stuck connected regardless if there is a phone tethered to the computer, and I have to restart! I still have had the data connection drop since OTA, but it usually fixes itself.

[Q] Freezing issues resolved with mod?

I'm now on my third G2. Sent the first two back in because they were having the freezing issue that's been documented here and on other forums that require a battery pull to get the phone back up. The second phone also had a dead pixel.
I have not yet had the issue with the latest phone, but have only been using it for a day and am not super optimistic given my experience with the first two. I'm still curious if the freezing is a hardware or software issue.
I'm wondering if anyone had this issue with their G2 and had it resolved by installing cyanogenmod or another mod. I have not tried rooting/modding yet as I knew I'd likely be returning the phones and didn't want to go through the work of having to undo it. It just dawned on me today that perhaps it's something tmobile has installed on the phone that is causing it to freeze. So I was thinking it might be possible that a non-tmobile mod might resolve it.
I had the issue on RC1 and haven't had it freeze since installing RC2. It would freeze while the screen was off and I had to pull the battery and let it boot up again.

Thanks for the reply. How long have you been running RC2?
Since it came out. On RC1 I had about 2~3 crashes within the first week of using it.

All of my problems were gone after the OTA update. It has been running like an absolute champ since.

I stopped having the reboots once I turned off the wifi sleep. If you live somewhere with lousy Tmobile coverage, but have wifi @ home, it helps a lot. Even helps battery life.

Bluetooth won't turn on, no matter what! 4.2.2

I am on 4.2.2 and the bluetooth won't turn on. As soon as i click ON, it immediately goes back to OFF (in blink of an eye). Is it due to the well known wifi-bluetooth issue? It happened yesterday when wifi was off even. Restart is the only temporary cure as for now. Any suggestions?
See this
The video isn't mine. Searched over the internet.
EDIT: http://forum.xda-developers.com/showpost.php?p=38966870&postcount=39
I also have this issue but its fine once I reboot. Still annoying tho

Same here. I dont know how Google released 4.2.2 without fixing a huge bug like this that affects daily use, its really annoying ;(.

Exactly. Although a restarts fixes the issue temporarily but it's pretty annoying as bluetooth is used daily and that too quite a lot of times in a day, sometimes. So constant restart really isn't a cure. Anyhow, I was wondering it's just me and this youtube user lol.. but now I know it's kind of a known issue and hopefully Google will fix it, since they know the issues with BT/WiFi etc. But I heard they fixed it in 4.2.2 however, we are still getting it which means the issue hasn't been resolved completely.
Edit: I was using Juice Defender Ultimate earlier and the issue started happening right after a few days of the said app's. installation. Googled a bit and got to know JDU is the culprit. So I uninstalled it on Saturday. But issue still persists.

Never had Juice Defender Ultimate installed on my phone,so thats definitely not the cause. However maybe another app is causing this ? Would be interesting if we could find out.
I am also glad im not the only one with this problem, but it seems like it isnt affecting a lot of devices .. I mean this thread is barely getting responses ? Anyway I hope this gets fixed soon.
Sent from my Nexus 4 using xda app-developers app
I hardly ever use the BT, but the only 2 times I needed it, it happened the same to me. Never used juicedefender, unlocked bootloader + root only.
It's not a big issue for me... but IT IS an annoying issue
I had this for the first time today. The only app I have that might effect it is Qualcomm Battery Guru.
Do you have frozen any service that might be linked to Bluetooth ?
Hmmm.. I uninstalled JDU after reading this thread:
http://feedback.latedroid.com/forum...ooth-cannot-be-turned-on-when-juicedefender-u
...but nothing really changed. So it definitely wasn't JDU.
Hmmmm..
Since a week I am facing another weird issue. I can't seem to transfer any files from or to my phone. Since Jpegs are of small size, they get transferred. But songs..videos..etc.. they just cant get transferred. For instance, a transfer will suddenly hang at..lets say...14% and will stay there for half a minute or so.. and then 1 file share unsuccessful will appear in notification. Out of around 10 to 15 tries, just once it transferred a 39 MB HD trailor.. otherwise it just doesn't transfer any thing.. Do you guys face this *hit too? What to do?:s
This Bluetooth not turning on issue is really annoying. Anyone has any news for it? No fix? Nothing?
I have to restarted my device several times in a day. And it extremely embarrassing when someone asks for a file transfer and you say him.. wait i need to restart the phone. BT isn't turning on
I asked a friend of mine, who has a N4, about this and he said it never happened to him. It seems that not all devices are affected with this bug ? Could it be a hardware thing ?
Sent from my Nexus 4 using xda app-developers app
Only had it happen once during the last three weeks so the issue is quite rare. Also had to reboot to fix.
You can leave Bluetooth enabled though, it doesn't drain battery whilst inactive.

Same here, have no issues. I did have issues with wifi not turning itself back on when I was using Qualcomm's Battery Guru. Are you using any type of battery saving app like Tasker? If you are try uninstalling it and see if that helps.

No. I don't use any battery saving app. I recently installed Battery Guru. But the issue was there even before installing it. The issue is there since the day I got my hands on the device. I seriously don't want to RMA as everything else is excellent in the device. Infact.. I seriously do not hear any buzzing sound from it.. even in a silent room. It was there in first few days but it was hardly audible. And now its gone. I have tried many times listening in a silent room but don't hear it anymore. So everything is perfect besides this BT bug I really really want a fix for it. No RMAing
The problem arises from the constant turning off and on of the bluetooth radio, as seen in cases such as the battery saving apps (Qualcomm Battery Guru, Juice Defender, etc.). I have the same problem happen when I automate the toggling of bluetooth using a Tasker created schedule. It is not limited to any particular app but has to do with a bug in the Android OS.
The official bug report is here: https://code.google.com/p/android/issues/detail?id=39688
You guys can star the issue to help raise awareness to Google so that they can fix it. For now, the only workaround that I have found is to just leave bluetooth on all the time.
Help!
Same happens to me. As soon as I switch bluetooth on it switches off. Rebooting doesn't work for me neither does doing a factory reset. Will this be fixed??
I am not having any issues with blue tooth and wifi

[Q] Constant signal loss

This seems to be an occurring issue for me everyday while using my Nexus 4. I would lose signal completely, and it would not ever find signal again, unless I switch airplane mode on and off really quickly. This happens when I'm at school, in certain classrooms. It's weird because on my old phone, I would get 2-full bars anywhere in the school (I'm on AT&T and have been for years). Any ideas on how to fix this?
I'm running PA 3.10 4.2.2 with Trinity Kernel, if that helps.
Thanks!
Try a different sim card of the same provider. Usually sims. Us be exchanged every 3-4 years.
They are vulnerable to ESD and poems occur if they have been bent.
Good luck

Im on my third sim and I still get this. Constantly losing signal and other phones with the same provider which is tmobile don't have this problem. I was hoping the update would fix this but it hasn't. I might have to rma as I can only think it is a hardware issue
