Random restarts, only rebootable with battery pull - LG G5 Questions & Answers

Hi there.
Hate posting these kinds of things as I know it's probably quite annoying, but I'm getting an odd issue, and don't seem to be finding anything completely similar in the search.
My G5 (UK, rooted, Nougat (stock)) seemingly randomly reboots several times a week. Worse still, when it reboots it seems to stick on the restart at the LG spinning screen. Pull the battery, let it reboot and happy days, but it decided to do it in the middle of the night last night and made me very late for work!!
Is there any way that I can dump some logs on what is happening? I just don't know where to start with this one, and have the fear that it could be hardware related.
Oddly any other type of reboot/shutdown and it will not freeze, so I cannot understand why it does it when this issue occurs... Any pointers?
Many thanks,
Dan.

Catlog was an app that we used to dump logs. (Back when i had galaxy s3)
Give that a try

Sounds like your getting bootloops. When did it start doing it? After you rooted or before? Fool around with anything root related? Try the usual fixes?

Random restarts

Hey guys just curious but has anyone else had any problems regarding to the phone just randomly switching itself off and then back on again? This has happened to me a few times now and thought i'd see if anyone else had, had this happen to them and knew what was causing it or any information at all really.
Thanks in advance to anyone who has any ideas!
Unless of course it is just me which would really suck.
I saw you debranded your phone.
Those restarts happened before too? If yes, you might want to send it to warranty.
If no, is the new firmware so, you might want to flash the old firmware again
Yeah sorry i should have mentioned that the random restarts occurred before and after the debranding. I think I may need to send it in
this same thing is happeining to me?? like once a day??? its really wierd...
I haven't debranded or anyhting and it has only started happening for the past week or so (I've had the phone for a month)
It happens to me when I connect my phone to my PC via USB and select "Mount".
Every time!!
Weird...
sadly this is a hardware issue... Whenever the phone warms up a little bit.
I didn't have that issue in the first months but ever since then and more and more frequently. Right now I'm fighting with o2 to get a new device, because this doesn't seem to be repaired.
Do the following test to make sure you have that hardware-bug:
Let the battery charge for a while. When you notice your phone getting a little warm, open a few applications (google maps, navigation, mediascape) whatever... The phone should immediately restart itself.
When you remove the battery cover it might also smell a little burnt.
Congrats... You're affected and it's only gonna get worse...

3VO Random Reboots, return?

So I got my Evo 3d and I'm very happy with the phone overall. The camera could be a bit better and the screen could have some better viewing angles, but other than that it's spectacular. However, I've been getting plenty of random reboots. It rebooted the first day I got it 4 times, then didn't reboot for a day and then it got into some weird reboot loop (5 random reboots right after each other). I did a full factory reset, no problems for a day, and then I turned on wimax and its back to rebooting.
Is this a software issue or should I just exchange it? My phone has a perfect screen with no dead pixels and am worried about losing that.
It seems a lot of evo 3d users are having some problems, how many of you suffer from random rebooting or freezing? I can tolerate minor bugs like the green camera thing, because I know HTC will fix those, but this rebooting is a bit much.

I would absolutely exchange that thing. The amount of rebooting you're experiencing is definitely not normal at all. Especially if it continued to do it after a factory reset. I had one random reboot when I first got the phone, and have not had one since. It was actually the first time I turned it on, and the phone was like 125 degrees, because the UPS guy left it on my doorstep in the hot Las Vegas sun!! I attributed it to the phone being overheated, because it happened within 2 minutes after I booted the first time. I would say your situation warrants a trip to the Sprint store..
Yeah, I will take it back. I'm just a bit concerned with how many of these phones seem to do this though. Who here has had a Evo 3d that hasn't crashed and restarted? Surely so many people can't have faulty hardware. I hope it's only a software problem. All I want is a phone that will be stable. It's something I haven't had for sometime since my old phone loved to randomly reboot too.
This is exactly how my old HD2 died, it would start freezing and then rebooting, the reboots would become more and more frequent until the device became unusable. Though that probably had more to do with how much flashing, overclocking and kernel tweaking I would do to it.
crashing and restarting on occasion's one thing, a lot of time that is the fault of apps
My first 3vo did this though, it crashed 4-5 times a day and would even worse just lock up and require a battery pull
returned it and the new one hasn't rebooted once in 2 weeks
definitely return it though
Yeah, I'll get a new unit but does anyone feel that the random rebooting is unusually frequent on this phone? I seem to have heard a lot about it, but I'm not sure if that's just the frequent complaining on this forum or real.

I feel it's unusually frequent. After you did the factory reset, did you refrain from re-installing your apps for a day or two? If not, try that. Do a factory reset, and try to not install any apps. Just leave it bone stock for a few days. If you don't get any reboots during that time, then re-install your apps one or two at a time, and monitor your phone's performance. If you start getting reboots again after installing a certain app, then there is a good chance that it's an app causing your problems.
However, there certainly does seem to be a common problem of rebooting, based upon the number of threads I've seen, and the number of people which have posted within those threads. The Evo4G was also plagued with a random rebooting problem, which affected a number of users, but also the majority of people did not experience that problem. There was just a batch of faulty phones that rebooted, for no apparent reason. Perhaps there is a similar issue with the 3d (unfortunately). You could also try running the RUU for the 3d, and see if that clears it up. (that will reinstall all the software). If all that fails, then exchange it. (this assuming that you're up for trying a few things to correct it, if not then I'd just exchange it)
But again, to answer your question...I feel the amount of rebooting your having is indeed abnormal. If that was happening to me, I would certainly exchange it. This is a brand new phone you purchased, and it shouldn't be doing that.
Definitely exchange it. I've had one random reboot in the weeks that I've had it so far. If it was happening every day, I'd get a new one quick.
Not sure if anyone has tried this but it worked for me so far. I travel alot for work and I cant deal with my phone rebooting all the time. I noticed more times that I was doing something that would access the sd card then it would reboot. So I changed the card out and have had 0 reboots since. Might be worth trying.
The random reboots is an issue that htc is aware of and is actively working on a software fix. Mine will randomly reboot a few times in a row then be fine for a few days.....
The first major update will come in august

Really? Do you mind posting where you learned of this? I really hope HTC is working on this. It's a shame that this otherwise awesome phone is being crippled by a few pesky bugs.

RAZR Screen Stutters Randomly

I own two different RAZR phones and recently they both have started doing something very strange. I will turn on the phone and notice that the screen starts to do a stutter when actions are taken (button push, screen swipe, etc.) After a little bit or a reboot the phone usually returns to normal. After a little while longer I see this happen again. I find it odd that two different phones started displaying this behavior around the same time which makes me think that it might be software related as opposed to hardware going bad in both phones at the same time.
Anyone ever see this behavior? Anyone have any thoughts?
Here is a link to a short video I made of the stutter so you can see exactly what I am talking about (sorry about the wrong orientation):

Thanks for any help.

Have you tried a Factory Reset to see if it may be some app you have installed that is causing the problem?

I used to have a similar problem after the ics update. It happened when I was reading news on flipboard. After I uninstalled it everything was ok. It got me freaking out, though
Sent from my XT910 using xda app-developers app
I think I got rid of the issue for now. I ended up looking at the most recently updated software and removing a couple of them that were not used much anymore and neither phone has experienced the issue since. Must be some sort of update that came along and caused an issue (maybe in conjunction with other software) and the OS. Strange...
Glad to know that it is not a hardware issue.

I'm having the same issues, its worse when I'm using the browser and keyboard. It acts like I'm touching the screen where I'm not. I have heard about golocker possibly causing the problem. Are you using a different locker or launcher? I found rebooting and wiping the cache help a little but it only seems temporary.

I don't think it is limited to a problem caused by one application. I think that is might be a combination of apps and how they interact with each other and the OS. I uninstalled about 5 recently updated apps that I did not need and managed to get rid of the issue on both my phones. I think some of them I got rid of were (Avast (Changed this to Vipre...personally was going to do this anyway), Lux, GSam Battery, etc.) Do I think there are problems specifically with one of these programs? No. They are all good programs. BUT, once I started seeing issues they were on the top of the most recently updated list and I decided to start there.
I use Titanium Backup and it has a list of apps that you can sort by the most recently updated and this is how I decided what apps I should look at to try to alleviate my issues. I knew the day that issues started and that gave me some clues as to where to start looking. It worked for me, but it might not have as good results for everyone.
Hope this helps!
Try this screen calibration app from play store
https://play.google.com/store/apps/details?id=com.assid.android.nookrecalibrate
Seems to improve the touch screens for my Galaxy Tab and Razr. Could be placebo though. A lot of positive results and comments from users of different devices.
my screen stutters in a similar manner, but only when running Google play music, plugged into a logitech speaker using the headphone jack. didn't happen on gb. Also tried a custom rom - DROID HD and the same thing happened, but not quite as bad.

Help with Random Reboots

Hey guys, my i777 has been random rebooting for 3 months now. I've tried everything in the realms of wiping, foctory reseting, ROM flashing etc. When I flash a new ROM (I like SuperNexus and CM9/10) the random reboots are happenning once a day. As time goes by, the number of random reboots reaches a number like 10, 15 per day, which makes the phone basically a black brick. I've tried identifying usage patterns that could lead me to a system fail (maybe some app could be causing it?) but it didn't make either.
It's a hard reset (it takes me back to Samsung screen) and I've tried everything, in every way, in every forum you can imagine, I've also tried looking in the last_kmsg log file, but it never gives me material to work with.
My last attempt to make this work is right below, I've recorded the logcat (it's really big!). I'd be very pleased if anyone with more knowledge in Android system than me could try to identify what's causing this. Thank you so much! The logcat is attached in this thread.
So you've tried going back to stock ginger bread, not installing any apps, and seeing if the problem persists?

Yes I have, keep getting random reboots. Is this a case of throwing the phone away and buying another? I have it for 1,5 years, maybe should be time to move ahead... This thing already gave me so much headache that I've already paid another phone in stress and sweat

As long as you're not adjusting voltages, sounds like maybe the power button could be sticking

Well, guess this could be my last try. I'll check it out and post my results asap... thank you.
There are tutorials on replacing the power button, from what I've read its not too difficult but I suppose its always easier said than done eh lol.

I had a similar issue, mine would reboot sometimes once a week, sometimes 5-10 times a day. Random sleep of death, freeze and complete battery drain etc. I finally sent it in on my square trade warranty and they replaced the main board - some sort of short in there that was causing it i guess. I suppose it would be possible to swap out the main board, or buy a used phone with a broken screen or something to strip for parts.
There is a great video by "le55ons" on youtube tearing down a I9100 that could help you get an idea of what's involved.

[Q] Help LG-P760 frequent crash

LG-P760 stock Android 4.1.2
Only basic apps, FB, gmail etc.
1. Factory/hard reset
2. Works around 3-4 days perfectly, then starts to crash.
By crash I mean black screen, nothing helps, only battery pull.
3. After first crash, starts crashing more frequently. Happens only in standby.
Worst was today: If I start phone, log in, then it wont crash before I put it in standby. First time in standby, within 30 second, it had crashed.
twice crashed when someone tried to call me. Vibrated once, then crashed.
I would like to avoid replacing my phone.
Any ideas how to find the source of this problem? Any recommendations?

I had the same problem with Vietnam Rom and it was the baseband. I changed to the baseband from ICS from a Rom of my country so I have Vietnam Rom+Original ICS baseband and everything works well.
Thanks.
Although, I understand it mostly is problem when you have unlocked bootloader.
I am running stock everything.
And they have problem with rebooting phone, mine crashes and freezes.
Weird is that it starts around third day of normal use.
I think I have to take on a quest with a warranty. Does anyone know, can I contact LG straight without the provider, where I bought the phone?

I haven't unlocked it. The problem was the same: SOD sleep of death, when the screen goes off you can't do anything but pull the battery.
But if you can use the warranty use it. You should find the warranty info in the box to know where send it in your city.

Thanks. I will search into it. Sleep of death is new expression for me.
I only have phone, it came from relatives who threw away receipt + box.
Luckily I managed to get new receipt from provider yesterday (I dont think they usually give out receipts twice), so now I can use local warranty.
Thanks everyone for replying. I will post update when I have final solution.
Since you are stock you might want to consider flashing the kdz to see if that helps. Good luck!

I'm having the exact same issue with mine. I've heard everything from "try a different SD card" to "factory reset," and nothing seems to permanently fix the issue. What I've found kind of sort of works is just reboot it a whole bunch until it finally comes up and doesn't do it any more. From there, I'm good to go until the battery runs out or I need to reboot it because all the bloatware is causing it to glitch. This usually means that I have to reboot my device 10+ times in a row every few days. Hopefully, you found a more viable fix than this.

Hi
I managed to kind of solve this issue. Because I am not sure how, I haven't closed thread yet.
Anyway, I warranted device, they re-installed soft. Came back, same thing. After around weeks use, SOD. Factory reset. After that, things went interesting.
I tried not to leave it idle. Always had something running. I also had noticed by the time it never occurred when it was plugged in or music was playing.
One day it did it again, but I was in a hurry and just disregarded it. I did something(I was busy, maybe just plugged it in automatically?) and it came back up. It took like 10 sec for screen to start, but it did just wake up. And it haven't had crash ever since. I have no idea is this solution or is this just some coincidence and I am not keen to factory reset again, to see will it reoccur. It's my only phone
TLDR: Managed to get out of sleep of death, haven't reoccurred since.
