[Q] Random restarts - G3 Q&A, Help & Troubleshooting

Hi there,
Apologies if this may be a bit of a superficial post but the phone in Q isn't mine so I'm working on second-hand info here. A friend of mine got a G3 off ebay that's t-mobile branded and is supposedly the European model, I haven't checked. (She's using it in the UK nonetheless). Also it has "the latest software updates" (whatever those may be) installed. The phone is not rooted or otherwise tampered with.
Her problem is that occasionally, the phone restarts apparently randomly, though she noted that this happened more when she was in the countryside and the internet connection was coming and going. My guess is that this may have to do with the modem, but not sure. She did some googling and apparently the problem is relatively common but there's no good solution to it.
My two (three) questions are:
- has anyone else encountered this issue?
- any solution to the problem?
- is this a stock firmware issue, ie would installing CMod solve the problem or is this a hardware problem?
Thnx

If it's second-hand phone it's battery issue.

Rushing toward CMod isn't going to solve your problem.
I am also facing the same issue. This also occurs when I'm at my village home. Mostly happens at the same place.
So instead of installing CMod try to change battery because stock Rom is also best and therefore any problem in it means problem in hardware not in software.
But you can still try different techniques. Also tell me if you can solve it.
Installing CM brought no solution for me and still faced random reboots.

i have faced this problem, adter everything i tried then i decided it is battery issue.
i mean change your battery

of course it works now like a rock

I've been having the same issue. My I've used a new battery but my phone acts the same as it did before. Reboots randomly after the wifi, bluetooth, and 3g crash and attempts to recover. The reboot never succeeds and I have to physically pull the battery. Currently using the latest nightly of CM13.

I have had the same issue. I have a stock ROM, fully updated TMobile G3 phone and when i would go to europe, the phone would randomly crash. When it was in airplane mode it would not crash, so i kept it in airplane mode unless i needed to call and i used the wifi calling feature. I thought it was the battery but i have the stock battery and an anker battery and i have never had this problem in the US, it only happened abroad.

[Q] Device becomes unresponsive after several minutes of use.

Hello,
I have an HTC Desire HD running Android 2.3.3. The device isn't rooted and I've never rooted it before.
I've checked on this site, and I've scoured Google all day but I haven't managed to find anything that matches my problem specifically, as explained below.
In the last couple of days I have been having a bizarre problem where after several minutes of normal use the phone becomes completely unresponsive or very laggy (to the point where it is unusable). This occurs whether I am using apps or simply looking at the home-screen.
The only thing that's responsive is the screen lock button, this works as normal. However when I then try to unlock the screen, the phone is still unresponsive and I'm unable to unlock it.
The only fix I've found (if you can call it a fix) is to leave the phone alone for a several minutes. If I do this I can once again unlock the screen as normal and continue using the phone, however after a few minutes of use it locks up again! This has been happening since last night now and I've found no way to break this cycle.
I did a hard reset to see if this solved the problem but it had no effect. The phone will boot as normal, and after a few minutes of normal use it will become unresponsive again.
I've also booted my phone without the SD card in just in case anything on this was causing the problem, still no improvement.
Has anyone else experienced a similar issue who could provide some insight as to what might be causing this issue? Any help you can provide would be greatly appreciated.
At first I thought this might have been a software issue, but as it persisted after the reset I'm beginning to think this might not be the case.
Thanks,
KaRsKiN
The problem is coming from the magnetometer. I have the same issue, please check this thread: http://forum.xda-developers.com/showthread.php?t=1394264
The only workaround I found is to disable screen rotation and do a couple of restarts (not switch off). Of course, no compass in the end, but at least I can use the phone.

It is possible that your battery could be failing. See if att has one they will let you exchange.
If its not the battery then it could be a hardware issue. Just send it in for warranty if that is the case. You should still be covered as the phone is not yet a year old.

How should this be connected to the battery...?
Anyway, I think that it is a software issue rather than a hardware one. Maybe something is running in the background, using 100% of the cpu. You could try CPUNotify for realtime cpu monitoring.
If that doesn't work, you should try the magnetometer way. Maybe it's a new issue. Never heard about it though
I do what i want, because I can.

I'm not going to explain in detail about the relationship of voltages and CPU usage. The battery being bad can and has caused these exact issues. Just like if a power supply is failing it can cause a blue screen in windows. In android the phone rebooting itself or freezing is the equivalent to a blue screen. Since they have never rooted and are on a stock rom there is nothing except a hardware problem that would cause this. If the battery is not the culprit then one of the many components in the phone can cause freezes and reboots if it is failing. Android os does not allow a single task to take over the CPU. This is not a windows os. So like I said, just use your warranty and get it fixed. Stock phones should not be presenting this behavior, you would have to root it to cause these kind of problems.

Thanks for your help! My dad has the same device as me so I'll try swapping out the battery to see if this solves the problem. If not I'll try calling HTC to arrange a repair.
Any news? Was it the battery issue?

[Q] Touchscreen problems after update?

The touchscreen stopped working on the phone a few months ago and a few weeks ago, after the phone had been dormant for a while, I decided to check if it worked and it was fine. But after a software update it stops working when you leave the phone for an hour or two, but if you turn the screen off and then back on it works (make sense?) Anyway, I'm assuming this is a software issue and there has been another update since then, current firmware is 4.2.2 and HTC Sense is 5.0, and I can't see this being a hardware issue. It doesn't really bother me that much but I want to sell the phone and I want it to be working perfectly when I do (I was thinking of putting a disclaimer but I fear the issue might worsen or the buyer will miss it). I've looked around for similar issues but there doesn't appear to be any, for most people it is a continuous thing (but it happened for others after updates as well.) Does anyone have any fixes for me?

Random reboots after Andorid 7.0 Nougat update

I took the plunge to Android 7.0 Nougat, however I am having some major problems. Initially I had everything stock, and every once in a while my phone would reboot when on WiFi. Sometimes it rebooted within 5 minutes of booting back up, sometimes it would reboot 1 hour after booting back up. There is a whole thread about it here (note: not the bootloop issue occasionally talked about in that thread, although it could be related I guess): https://productforums.google.com/forum/#!topic/nexus/kaMOvuf093Q
I was wondering if anyone else has run into this issue? It definitely seems to be linked to WiFi only. A bunch of users apparently narrowed down a few apps that triggered the reboots more frequently (Napster, for example), but the problem seems deeper than just a rogue app. Safe mode does seem to alleviate the issue, but this is not really an acceptable solutions to me. I tried another kernel (Franco's), but that didn't fix anything. I was wondering if anyone who had this problem had any success fixing it by changing ROMs or kernels? I also read that turning off WiFi scanning may also help--I will report back if this fixes anything.
Any suggestions welcome, thanks!
This could be part of the hardware issue that is happening, it talented to me and I finally have my phone back

I have a H-790 Nexus 5x on Verizon.
has been happening to me too -- reboots randomly about once or twice a day. (only realize it since fingerprint scanner does not work and i am forced to key my passcode at first login post reboot).
It seems that the H 790 production series are faulty
Nexus 5x reboot problems
Yes it would appear so. However, I have read one post in Google Forums that speaks of problems with H791. However, it could be related to the wifi problem. There are two problems - one is problem booting initially and finally phone does not boot into the ROM and cannot be recovered. This seems to be related to hardware problem in H-790 series. The other has been isolated to the WiFi scanning which causes a crash.

Yeah, I am definitely having a problem with the WiFi crash. Would a custom kernel fix this? A custom ROM would, right? Any ideas for a fix for this?

I thought the bootloop issue was hardware related, but not the random reboots issue? Ex: Safe mode fixes the problem for me.

IMO opinion this is just the eMMC dying problem that people have reportedly sporadically over the past 12mo. That problem has affected both H790 and H791. It likely just became more likely to show up after the 7.0 update because that was a large update, but by no means is a large update going to cause the problem by itself. The core problem is eMMC that was waiting to fail and could have happened just when web browsing but a large update just pushed it over the edge. Some phones you can do many large updates and never see a problem, then boom, one day randomly it just reboots and bootloops, with no amount of flashing or resetting making any difference.

If safe mode fixes the problem, then I was wrong. Try to find which app conflicts with the system and uninstall it

I really wish Google would fix this, this isn't really an acceptable solution to me. :/
I have a h790 nexus 5x and haven't seen this issue, knock on wood. However if it's linked to wifi scanning that was issued in another post you may try disabling wifi scanning to see if the issue is resolved. If not it's definitely the emmc in my opinion

If it is indeed not a a hardware problem, then don't wait for Google to fix it overnight. Besides, it may be the case that there is no bug at all, and you flashed a corrupted firmware. Your Best bet right now is to try some custom Roms and kernels and see if it fixes the problem. If you don't want to mess with user made firmware then I would suggest you to reflash the latest stock image form Google. If both of the above fail, the you are forced to roll back to marshmallow
You can try to disable wifi scanner on sleep,.
After the Nougat upgrade, I was having random reboots on my 5X (LG-H791). It always happened when my 5X was sleeping (laying on my working desk or on my bedside table for some time). After the reboot it was working fine again for some hours, so it does not seem to be the bootloop issue. I remember that I had a few rare reboots after upgrading to Nougat 7.0, but after the last 7.1.1 upgrade the reboots occured at least every second day.
Last Friday I had enough of it. I downgraded to the last stock Marshmallow 6.0.1 (MTC20K), and it didn't crash a single time after that.
My wife's 5X is having the same random reboots. The reboots are less frequent (but still occur) when WLAN is turned off. I will downgrade her's too, if my 5X is still still stable after the next weekend.
I wonder if this is a different problem, or if this is just a first symptom of the bootloop issue. If it's a bug in Nougat, then shouldn't much more (if not all) 5X owners experience these random reboots?

hi, i had the exact same problem with my nexus 5x from carphonewarehouse (uk), and when it was given in to repair i was promised money in return, however they ended up refusing to give money and gave a replacement phone instead, the only way to fix this issue is apparently to get a replacement, as it is most likely a hardware issue google haven't accounted for
I've had the random restart issue for a while now. I got a "new" replacement in November for a different issue and have been on 7.0 the whole time (until last week when I got 7.1.1 OTA). I'm going to call today about another replacement. I've just had two restarts in the last hour.

Random reboots OOS 4.0.x

Hi,
I'm experiencing random reboots since I've upgraded to OOS 4.0.x (I've had them since 4.0.0, but I've got them too on 4.0.1). My friend has the same issue. I think its weird that I find very little about this issue. I think it happens the most when switching from LTE/4G/Mobile to WiFi and vice-versa. I can not say that the reboots only occur when switching.
OnePlus support suggested me to do a clean flash of the rom. (Isn't that the same as a factory reset? I did not have tampered with my phone.. Everything is stock. (ROM / Kernel..) Even the device is not rooted and the bootloader is still locked..
Are there other people who have this issue?

I have been experiencing the same situation with you. Sometimes during charging, sometimes just randomly.
Your suspect with network/wifi switch could be right as my network quality is quite bad and it jumps around quite frantically. I did clean flash but still issue persists

Nope, I got a Chinese one too and i have really got issues with that random reboots, because my alarms dont work anymore after a reboot.
I'm on Open Beta 10 and have the same issue, on a clean flash. See screenshot attached. Not sure what's going on. Phone was plugged in each time but one.
Collegue of mine has the same issue, (also OnePlus3), other friend of mine has also the same rebooting issue. (OnePlus3).
It's weird that I don't find as much information on the internet regarding it..

Question WiFi not turning on

Checked around the internet and this problem seemed to be quite common.
WiFi could not be switched on. See the YouTube link below at 1:20mins.
Question: has anybody tried to Odin reflash it to the same/latest firmware. No rooting or anything fancy, just reflash the same firmware.
I had this issue after updating to the latest firmware but I don’t think the issue happened right after updating. Probably a few days later. I was hoping if this could fix the issue.
Thanks.
Update.
I tried it myself via Odin updates to the latest/same firmware for my region.
Problem not fixed. Same thing. WiFi still doesn't turn on.
Same situation here. Wifi not turning on.
it was working while phone was in folded mode.
As soon as open, wifi won't work. Then phone goes to restarting.
Did factory reset and no help.
Came here hoping to reflash old stock firmware to see if it will work, but you have answered above.
I read on some of forum and one guy sent in to Samsung and they changed screen and it is working like a new one.
Maybe some to do with wifi antenna built in to the screen or something?!
Coincidentally I have the person installed a new screen protection and that person didn't know well and rubbed hell out of screen. That was about a few days before my wifi went out.
????
What do you think? Maybe relate it, or not?
P.S. I have less hair on my head now and not cause of being old (66).
99% is software related.
anybody has installed oneui 5.1 and still facing this issue?
i bet no coz sammy is aware of this problem and pushed the fix with latest build.

updated today to 5.1 and I got the same issue. looking at the history of this problem it seems to me that samsung are not aware of it because after almost a month they still released the 5.1 firmware.

This looks like a hardware problem to me. Something inside is disturbing the WiFi radio when you unfold the phone.
