Lg g8 AT&T random reboots - LG G8 Questions & Answers

I have problems with my device, it has random reboots, I already tried the "soft reset", "hard reset", restore factory data and follow the reboots out of the blue.
I already tried it without apps and it gives me the same inconvenience, I'm in any app and as soon as I see it, the startup animation comes out (operator's lg-log).
I don't know what to do, because I can't even find the ROM for my LG G8 (LM-G820UM) AT&T Unlocked version, I also found out that it can't be crossflashed because it has a factory lock for that task.
The little I have touched is to accept in the first start of the smartphone the LG contract completely (3 checkbox)
And disabling some of the extra games and apps that came with the phone.
EDIT: an additional fact is that in the developer's options I have modified the following
Night mode: always on
Screen animation scale: 0.5
Animation transition scale: 0.5
Scale during animation: 0.5
smaller width: 500
And when it restarts or automatically resets (as mentioned above) the DPI returns to 411dp
I don't know if that has anything to do with the sudden restarts because the same way with 411dp it happens
Thank you in advance for your prompt response

Look up how to boot it in safe mode and see if it happens there

I already put it in safe mode, I used it 1 hour without problem, now what do I do?

Well that means it's a faulty app probably. Just look up what safe mode allows you to check and what the problem could be

Isn't there a more accurate method of detecting that?
Because all the apps I use are downloaded from the official play store.
And they are the same apps I have installed on my LG G6
A while ago I was on wsp and it came out "Google play services does not respond, the twitter went off by itself, or SwiftKey stopped working..
So I don't know what the problem could be.

I had this problem as well, seemed to happen early morning when the LG backup was running, turned that off and it hasn't happened since

Could that be it?
Because this is the fourth time I've reboot my phone and they're shutting down:
-SwiftKey stopped working
-Google chrome comes up with "oh no"
-Google play services has stopped
-Fb lite stopped working
-Instagram shows no message but exits the app and sends me to the main screen
-Youtube rarely goes out
I'm gonna try what you say about lg backup, where do I find that option?
If anyone else has this problem and could solve it, I'd really appreciate your help
Thank you in advance

[Q] Loading problem

I recently got HTC one x in UK and it was fine so far now I started receiving Loading screen often.After seeing various forums I removed the calendar widgets with the hope of not getting he loading screen again but no luck. Any one had this problem or any suggestions?

Hi,
Not sure if you still have this problem, but I solved my friend's X by backup and factory reset. after restart, tested opening apps then home button, no more Loading..., then restored.
Hope this helps.
Thanks dansoh, Same I did and it started working fine but my worry is why the new phone needed such factory restore?
I already did a factory reset on mine and it still happens. I think when the phone runs out of ram, it may have randomly closed the home screen and so it needs to "load" again.
This sometimes happens with my galaxy nexus as well.
I had my homescreen always reloading again to.
Found out it had something to do with the setting: Options\Developer options, and there the 3rd option from below, don't save activities (not sure how it is displayed in the English version).
It should not be selected, otherwise it reloads the homescreen everytime.
I see that option. By the sound of it, i think it disables multi tasking?

i got the same problem too and it was yesterday it started as there was a new software update and i accepted and ever since, when i hit the home icon on the phone it says loading every time.. i followed all the tips of putting everything to 4 processors and turning off activity in the background and no luck.. i have noticed that when i go onto the task manager i have constantly over 641mb running even when i stop all and refresh.. where as before i updated it it was around the 300mb ... can i get the old version instead of 4.0.4 ? or is there another way ? thanks

Phones freezes for 2 second then reboots, once a day, immediately after waking up

I've had this problem sometime over a month now, can't remember if I did anything to make it like this. I made a post somewhere about it happening the 17th of May, so it started somewhere before that.
My phone will freeze for 2 seconds and then reboot itself.
It started while I was on stock 4.0.2 and now I'm on stock 4.0.4 IMM761. I have a GSM Galaxy Nexus.
It only happens just after the phone has been woken up and something is started. The most common (as it's my go-to-way of forcing it, to see if it's still there) is after waking up the phone, sliding down the notification bar and pressing "settings", which doesn't open but the phone freezes and reboots itself. I first discovered this when I wanted to go in there to change screen brightness. It's also happened when I went into the notification bar and pressed a battery app there. It doesn't matter if I'm doing it in the lock screen or after the lock screen.
It's also happened when I wake up the phone and enter the camera through the lock screen.
It also regularly happen if I set an alarm in the morning. When my alarm is suppose to play it freezes and reboots, and when it's rebooted, the alarm has been cancelled without ever playing.
It doesn't need to wake from deep sleep to do this, I've had it happen mere minutes after trying to see if it's there.
I don't know if it has something to do with this, but the 21st of April I tried to do the "clear google services framework" trick to force 4.0.4 ( I was on yakjuxw), but it did not work and I remember my phone acting janky and I was scared it messed something up, but I seem to remember it getting better. I can't remember what exactly it did though.
I've read that 4.0.4 would fix the reboots that a lot of people were having (don't know if it was the exact same kind of reboots as mine) so I did this to make my phone a yakju (translated from Danish):
http://translate.google.dk/translat...at-modtage-opdateringer-til-din-galaxy-nexus/
I did that the 8th of June, and it worked flawlessly and I was on 4.0.4 IMM761 in no time. Unfortunately it did nothing to stop these reboots.
As part of the process of making my phone a yakju I, of course, did a complete factory reset, although I did make a copy of my entire SD and transferred everything over again after the process.
These past two weeks I've tried the following to fix it:
Clear cache partition in recovery.
Clear google services framework.
Clear media storage.
Tried to uninstall many apps, 2-3 a day, to see if they were causing it, re-installing them when I still had the same problem. If it's an app causing this I've yet to find it, but I find it weird that an app could be causing this.
It happens once a day, but never close to each other. It seems that some time has to pass before it can happen, and it only ever happens just after the phone is woken up, either by my alarm or by me opening the notification bar and pressing something there.
Please help me, this is unbearable.
Another thing, yesterday I tried to let it run without me pulling down the notification bar and pressing "settings", which would set off the freeze-reboot. I found that my phone would not freeze-reboot but very often it would "reload" app icons and widgets when I went around my homescreens. Where I can only see my wallpaper for half a second and then the icons/widgets appear. It would do this very often throughout my 1day 5hour uptime, and a couple of times I would try to force the reboot (by pressing "settings" in the notification bar), after the icons/widgets did the invisible/load thing and it didn't reboot. This must have something to do with it?
hi,
experienced this on my nexus s back then what i did is from recovery>mount and storages>formatted system, boot, and everything else except sd card.then it was all gone.btw you will have to flash your rom and kernel again as this is a full wipe.hope i helped and do this on your own risk

I haven't tried that yet. I'm trying a "RAM booster" app to see if that helps, but that doesn't sound too stable even if it does.
I'm going to do a full factory reset and installing nothing, or moving anything to the SD, and just let it run like that to see if it works.
Just writing an update for anyone googling themselves here with the same problem, I had it resolved.
I found out that if I didn't force the reboot (by turning on the phone and quickly pulling down the tray and pressing something there) it could last a long time with just the launcher resetting, but it would lead to complete freezes (anywhere I was on the phone) and would require a battery-pull.
My plan was to wait for jelly-bean before doing another factory reset, I got the JB update and it completely removed the problem. I still don't know why the problem suddenly started or what caused it, all I know is that the JB update fixed it, and the update is fantastic, my phone's never been better.

Phone slowing down?

I am using a HTC One M8 (ATT model, Best Buy edition)
There are no threads about this issue that I haven't checked: my phone seems to be acting not only sluggish, but some other weird things seem to be happening.
- Google Play Store seems to be taking forever to start to download, downloads fine, takes forever to start to install, and about 20 minutes later (if the app hasnt been killed off by then since I have only 1 app in the background, to see if that fixed my lag issues before switching to just 1 app in background) it finally installs.
- Quickpic doesnt seem to want to load anything at all (I use it as my main app to view pictures since HTC Gallery cant view animations in a loop). It just sits there at a black screen with a loading circle at the top, no thumbnails or folders show up. I have cleared the phone's cache with
- Rebooting does nothing to solve my issues.
- Restoring to factory default does nothing to solve my issues.
- Restricting background processes to 1 does nothing to solve my issues.
- Disabling Power Saving mode entirely does nothing to solve my issues.
- Disabling apps that I don't use does nothing to solve my issues.
Anyone know what my issue is and how I could fix it? This would be extremely helpful, thanks.
FYI, I am not rooted, I will save this as a last resort if need be.
**Edit** using App Cache Cleaner app, apparently my phone storage is at 23.6 GB/ 24.8 GB. Will try seeing if cleaning up some stuff manually fixes this.

Seems weird. Install CPU spy and see what frequency your processor cores are running at.

Wow I derped pretty hard, the issue was fixed when I checked the box with "Erase all data" under Reset Phone. Didn't check that when I reset it the first time. Guess I had too much media on it...?

Glad you sorted it out. Too much media should not be an issue, but a complete wipe will usually fix things.

Chime in if you recently are getting random reboots/bootloops/"optimizing apps"/etc

Chime in if you recently are getting random reboots/bootloops/"optimizing apps"/etc
Over the past few days my G4 has been infinitely more laggy that before, and then started getting random reboots, bootloops, and occasionally would "optimize apps" at startup multiple times in a row. When it shuts off on its own, 50%+ i have to do a battery pull to get it to start again and then it may bootloop or never even make it past the LG or the AT&T screen.
At this point my phone is unusable and a warranty replacement is on the way. It wont stay on for more than a few minutes tops. I'm getting fearful there is some flaw that is emerging if other people are experiencing the same thing around the same time.
This is on an AT&T 810, rooted on 10e firmware.
If you're also having issues, list your model/firmware as well.
Thanks,
yes!
I literally just had the same type of question haha! http://forum.xda-developers.com/g4/help/optimizing-apps-1-233-rising-t3224808
I have the H815, running on 10b firmware
Its so strange i hope someone can help!
Do you by chance have xposed installed? This started happening on my Note 3 after I updated to L and installed xposed. If not, I don't know the problem but if it's xposed, prolly have to remove it.
I had this happen to the point where the phone wouldn't boot up anymore, it would hang on Android, and then fade to black. I sent this issue to the sprint store and got a brand new LG G4 in 5 days. Just get warranty and say the phone won't turn on, and get a factory fresh LG G4 in a week or so.

Have a warranty on the way, my concern is the warranty phone will be on a later firmware with the anti rollback counter past the point of no bootloader unlock in the future. We shall see. Shame its working out this way.

Some ideas
YES. I joined just to post this reply lol. I have an unlocked H815 (Bought from Amazon, included documentation was in Czech, Slovak, and English) and I've been having this issue for weeks now. I couldn't find much on google and thought it was just my device, but now it seems more and more people are having the same problem. It is incredibly frustrating and it hurts.
Symptoms:
- Randomly (6-7 out of 10 times I want to use the phone for whatever) it'll throw itself into a reboot frenzy til it decides to stop doing it whenever, usually after 5-15 reboots or about 5-15 minutes.
- During the reboots, sometimes it'll reboot even before the phone boots up at all (on the LG boot animation).
- And for the times it does boot up, it'll reboot again within up to 20 seconds or so.
- Some reboots are immediate - phone shuts off and turns on again immediately randomly. But for some reboots, the phone freezes briefly before the reboot. On some of these freezes, there's a horizontal screen glitch at different heights every time.
- During the reboots the phone overheats considerably.
- The battery drains very quickly during the reboots. Percentage "skips" occur frequently.
- It also sometimes "optimizes" apps...
- The number of apps it needs to optimize for whatever reason can be different (I pulled the battery out several times when it was "optimizing", and the number would vary; though it did not boot at all until it finished "optimizing" apps, which took forever).
- Not sure if related, but just 3 days ago completely out of the blue overnight (no updates or anything) the camera developed a green blotch on the upper right-ish side too; seems to go away or get stronger depending on lighting. On google I found a Taiwanese H815 having an identical problem too so it can't be a hardware problem; also due to the fact that it almost immediately disappears when a different camera app is launched under the same conditions (such as Snapchat).
Device:
- Unlocked H815 European model.
- Kernel version 3.10.49
- Build number: LMY47D
- Software version: V10d-EUR-XX
- No root. No unlocked BL. All stock except the launcher (Nova). Plenty of storage space.
- Network is T-Mobile and have a 32GB MicroSD inserted.
What I've tried so far:
- Tried using the phone without SIM card. Did not help.
- Tried using the phone without MicroSD inserted. Did not help.
- Factory reset and immediate restore from LG backup. Did not help.
- Factory reset and no restore - only contacts. Seemed to work fine for almost a day, then problem came back. Probably a coincidence it ran okay for a bit.
- Since the phone overheated and the battery drained very quickly during the reboot spells, it stood to reason that the CPU was being stressed considerably. Most likely by some app or process obviously.
- Tried disabling some "stock" apps after a clean factory reset (the stock apps were the only apps on the device). Tried Google Play Services, and most other Google apps. Tried a few LG apps too. None worked.
- Tried updating some "stock" apps after a clean factory reset; same apps as above. None worked.
- From developer menu, enabled "Show CPU usage". The goal was to see what processes are running during the problem to see if it's associated with a memory leak or a CPU stress. No process seemed to stand out. No memory or CPU leaks as far as I could tell.
- Enabled event, kernel, main, memory, power, radio, and system log from hidden menu (277634#*# -> SVC Menu -> Log Service -> Log Enable). After a random reboot, copied log files to sd card from the same menu in hidden menu and tried to analyze them to see if there was a smoking gun. Logs are huge and I merely looked at the end of them, but to no avail so far. Interestingly though it seems the kernel log was cut mid-line on the last entry...
- I also noticed that after a factory reset, if you opt not to restore from a backup, the phone requires an internet connection to be set up. After the phone is ready for use, the Software version is listed as V10d-EUR-XX. The phone did not ship with this version. I believe it was V10a. For whatever reason, even after a clean factory reset, the phone runs the seemingly latest Software version. Not sure if this information is of any use, but it may be relevant.
I love this phone and when I got it, it was working absolutely flawless. Now with the software updates it seems it's just gotten buggier by the day to the point which it's pretty much unusable now, very disappointed. Hopefully this info will be useful to some of you out there.
Same here:
http://forum.xda-developers.com/g4/help/g4-bootloop-t3223130
TLDR;
-Not Rooted/Not BL Unlocked
-Reboots/Bootloops/Optimizing
-Resulting in "not fixable" Bootloop
-Phone in Warranty/Brought it back to retailer
-Don't know which Firmware
-H815 unlocked
-Messaged LG-Customer Service Conversation translated to english in Thread
Really not impressed by LG so far (First Lg Phone i own).
i think i'm gonna chime in....
these kind of things happened on my fellow G4 user here (H818P)
one of them have found and proven that on his V10D H818P, if the phone stays on for longer than 30 minutes, every reboot will start as optimizing apps
and one of them had worse luck: he was laying his G4 on his work desk and when he's about to open a newly arrived text message, the phone suddenly reboots and bootloops until no end.
thankfully one of them got the mainboard replaced, while one of them is still waiting for the warranty to be processed
Same issue is happening with my H815 now - unrooted and no modifications. Constant reboot loops or if it does boot up, it'll shut off randomly and go back to the reboot loop. Unfortunately, I have the Taiwan version and live in the US, so I think warranty coverage is not likely.
wow.. I just got this phone yesterday and i'm getting this bad. of course it was from a 3rd party seller... no fun
more info
tmobile
brand new
occured on 10h
updated to 10n and it's still happening (Update: Only happened once)
is this real life?
Update: I seem to have gotten past the problems after updating to 10n. Now running stock debloated 10n rom with no reboot issues (so far)

Question Power button being slow?

Fully stock not rooted
Using the power button the phone lags to turn on or off. It's not everytime but most times. It's not long it's only a second or two but it's enough to annoying. Rebooting doesn't fix it, just wondering if anyone else has this happen?
can you post a video?
could be so many things, even animation which seem to make unlocking process a bit slower. change animation to 0.5 or 0.0 and see if it fixes it.
also maybe try booting into safe mode and try it there. Are you on the January update?

On January update but it was doing this on November update too. Always had it set to .5 on all animations. I'll try to get another phone to record it

its hard to say without looking at it or comparing it to another pixel. But change animation scales to 0, then to 1.0 and see if it makes a difference. Boot into Safe mode and check if it happens there (just bring up the Power Menu where it shows Restart, Shutdown etc) and hold down the Restart Option. Once in Safe mode, try locking your phone. Is it 1 or 2 seconds? or 30-40 miliseconds? more than .3 seconds is a lot to unlock the phone.
But again, it might be normal behavior, it might be an issue with an app (like the Accessibility touch input bug that google finally acknowledged). Or it could be something deeper than can be resolved by wiping the phone and reflashing the factory image (and testing the device without logging into a google account or wifi during the Android setup wizard). So hard to know, but If I were to guess, it's a third party app that's causing it.
