let me start off by saying ive worked on two galaxy Tab pro 8.4's, one is mine one is my dads. my tablet has no issues, his however crashes after a little while of being on ANY Rom. we have tried Cyanogenmod, Slim Rom, and Resurrection Remix, all of which i have installed on my tablet without any issues but after a while on any of them it just goes into a bootloop. This is what i do every time I install a new rom-(1) Boot into TWRP (2) Wipe everything except SD card (3) Flash Rom and appropriate Gapps. am i missing a step? am i doing anything wrong? At first it looks like it is working then after a week or so it just goes into a boot loop. I am confused because i don't so anything different on my tablet. any help is much appreciated.
Try using one of the debloated stock roms

Sounds to me like it might be a Battery / Battery connection problem. Especially if the Device just suddenly dies - reboots like that.
In my experience random reboots just happen. Perhaps once every few weeks or so? But I hardly if ever actually turn my T325 off.
I dare say the only time it ever gets to that state is if the Battery has reached that level of depletion.
*Edit* So probably 'cause of that, and having amassed a lod of crap in that time, and so just the one random reboot happens.
But, I can recall having replaced the Motherboard in my Device, which I placed into a replacement house, after trashing the Display on my first one. Which had such random boots, when otherwise held normally. Eventually reseating the Battery Connector managed to fix it for me. Like I said Random reboots are a thing, and they will happen, in my experience even on stock Firmwares. Especially if you never really ever do a manual reboot from time, to time.
But, such sensitive crashing, rebooting, caused by just looking at it funny is not normal, and IME is likely down to either a bad Battery, or more likely a poorly connected one.
Thank you, i will look into this. Its a definite possibility.
Did re-seating the battery work for you? I have a Tab Pro 8.4 that has been doing a lot of random reboots lately -- I also have tried a lot of ROMs (including the three you mentioned) and things only seem to have gotten worse, which is why I suspect a hardware issue. I'm typically at one reboot every 10-15 mins of use. Any suggestions welcome.
reseating
reseating the battery does wonders, it stopped the bootloop for me and increased the battery life as well, you just need to be cautious when u reseat it

My GSM Galaxy Nexus has been experiencing random shut-downs, especially when it is in my pocket. I haven't noticed any problem with overheating and I tried rooting it and installing the latest version of ICS 4.0.4 directly from Google's source.
I also have Lightflow installed, but I doubt that it causes shut-downs, since I've only heard of reboot problems.
I suspect it could be a problem with the battery because, whenever this happens, the charge level goes down by at least 5% or more.
So, does anybody know how to remedy this? Or will I have to exchange the phone?
This has happened to me a couple times. I never know how long it's been off. I'll take it out of my pocket, and it's just totally off. I hold the power button and it starts up. Very frustrating bug though... as rare as it may be.
I'm still stock, unrooted 4.0.2 using the extended battery on VZW. Holding out for the first update, then we'll see...
Just so you know next time that happens grab a log and post it. Also, if you battery is down, try wiping stats, that usually brings it back.

Sorry for being such an ignorant and a noob but by log you mean a crash log right? Which is the best way to obtain them?
This happens to me about once a day. I'll come back to the phone and it will just be off. I aslo have root and lightflow installed. What's the best log to get?
It was the battery for me...
This was happening to me too, almost every time I took my phone out of my pocket, it was turned off.
After a couple weeks of troubleshooting and googling, I figured out what it was. It was the phone getting "twisted" in my pocket from sitting and standing. If you twist your phone like your're trying to wring water out of it (not too hard), the battery loosens just enough to cause the phone to lose power. I fixed this by taping a thin piece of foam to the inside of the battery cover to keep the battery in place. Makes the back of phone feel firmer too.
Hello !
I'm experiencing the same kind of power off.
Very often it's in my pocket, but sometimes not.
I've leave the debug mode on for the day, so last time it happens to me i've save a "abd bugreport" to a file.
Is there any clue that can be found in this file to know why the phone shutdown ?
Regards,
Antoine
EDIT : I have YAKJU 4.1 stock ROM, no root, no unlock.
I noticed a while ago before seeing the videos that if I banged my GN against the table a certain way against its bottom left corner that it would shut down. I solved that like the poster above by putting an extra something in between the battery and the cover (paper). That solved lots of the problems I had with my phone shutting down when I put it down on hard surfaces. There is though, I believe, a second software caused issue for some of the shutdowns. I still pick it up once every couple days to find that it's off. I've banged it, tapped it, twisted it, and I can't get it to shut down physically like that anymore.
I'd like to know more about how to pull the logs and find out what's going on.
I've had my Nexus for three days now, and I've had several shutdowns. Two of them were during a phone call, and the other two were during a workout using micoach app. The twisting/pocket option doesn't apply to me, because during the calls I was holding it in my hand, and during the workout it was strapped to my arm. I also have lightflow, and will uninstall to see if there is any difference. Running totally stock unrooted 4.1.1. This is making the phone totally unreliable, and I will return it if I can't get this fixed soon.
Every would have had that problem due to how poorly Samsung constructed the battery slot for the battery to fit it. What I did to fix that problem was take out the battery. Even from time to time rage quit and rip the battery out while the phone was on. And put it in, and push it a bit up toward the camera. That fixed my battery issues. Others have put a foam thing (sorry I don't know the name) where the battery slot golden things were so the battery wouldn't move. You can also try that.

I uninstalled Lightflow after posting my previous message, and since then have not had any random shutdowns. All calls are performed flawlessly, and I've used micoach several times again (this was when the problem was most obvious) without any problem. I haven't changed anything else, so I'm pointing my finger at Lightflow. I'm installing it again to make sure it was the cause, will report back.
Regarding the battery problem, I've been looking at it and can't see how it can become loose. It is really tight, and there is no spare room to add any kind foam. Maybe thye have tweaked the design on later batches? My GN was built March 2012.
I had the same issue and it was caused by an app. The app "Boid", a twitter client still in beta, was causing the reboots. The reboots occurred once or twice a week, they happened on 100% stock ICS, 100% stock JB, custom roms also.
Like the above poster, I uninstalled LightFlow and am no longer having any issues. I'll try and get in touch with the developer and see if there are any logs I can get to help.

Hello all!
I have noticed that recently, my phone has been doing a very odd thing while charging. When it has been plugged in for a little while, and the screen is on and in use, sometimes the phone will crash. When it crashes in this manner, the backlight on the screen is turned on on full brightness, the screen gets a yellowish hue, and horizontal black bars start appearing on the screen. More black bars keep appearing until I reset the phone (hold the power button), and then there is no evidence of any screen problems. I also generally have to unplug it for a while, as if this happens once, it generally happens multiple times until I unplug the phone and wait. These problems seem to be occurring at odd times (a lot at night, before I am going to sleep), and have just started happening (I also recently made the upgrade from the latest version of GB to 4.0.4). I have had this device for about a year now (the second device, the first one had a physical design flaw and was replaced), and I am out of warranty right now, so any help would be appreciated!

That was happening to me (for a weird reason, my devicewas new, its seems that problem is more common in the rogers version dont know why) but, if your problem is the same problem that i had, then, just install stock ICS with oneclick (dont remember the name very well)

Superoneclick? That's the closest I found, and it doesn't say that it supports the Glide. And, I am running a fully stock version of 4.0.4, unrooted and everything. I might need a little more help here, haha.
I mean, oneclick, is the firmware,and is about 700 mb, give me amoment a will search it
EDit: i found it: http://www.androidauthority.com/captivate-glide-sgh-i927-att-android-4-0-4-ics-uclg9-leak-110365/
I use that, when I install it, that problem gone away, try it. And then, you can flash the custom recovery and install custom roms

Isn't that a different version though? The build number on that is UCLG9, not UCKJ3 (which is what I have right now).
I am not sure, but, if with that your problem persist, maybe is hardware, but I only do that. When I did it, that was the latest version, now there is another version but not sure what is it
I was having the same problem, except it was happening frequently after my phone had warmed up due to normal use. If the phone was already hot it wouldn't even get past the splash screen.
I put it down to hardware fault, and was successful in getting it replaced under warranty. The new one has been totally fine.
Hopefully yours isn't a hardware issue - but from how it sounds it very well could be

I really was hoping it was a OS issue, as it hadn't ever done this on GB. If I flash a new rom then, it would be fixed?
Also, I too noticed that my phone is abnormally warm when it does this. I do have a cover on my phone, but I noticed that it seems to be centered about on the horizontal center of the phone, about a half-inch below the camera. If this is related, what do you think it is?
My phone did this as well. Luckily it happened just before I rooted. The att guys said it was a hardware fault and that fault also killed my battery. I'm assuming it was a short. It started as something infrequent, but it eventually escalated to the point the second I turned it on my screen turned completely green and got really hot.

Just great, a possible hardware problem while out of warranty. Did yours do it only when charging as well?

Didn't have to be charging to do it. Could have been on the street holding it. (I was on GB as well)

Your issue sounds similar, but slightly different. Mine only happens while I am charging it, and it has only done it since a while after I made the upgrade to 4.0.4. Although, they sound similar, and my phone also gets concerningly warm, so I have no idea if it is the same thing or not...
If it's out of warranty, then you have nothing to lose by doing a backup and a clean ROM installation, which is what I would do. I guess if you do it when fully charged and while the phone is cold you should be fairly safe, especially if you use a small ROM. I've found the latest M3 10.1 ROM installs fairly quickly, so that might be worth a shot even just to see if it fixes the problem.
The only risk you're taking is that the phone might die and get bricked in the process if it's a hardware fault, so I guess it's really your call.
EDIT: On that thought, perhaps experiment with seeing if you can charge after leaving it in the fridge for about 15 minutes? It's a trick we used to use to recover data from failing hard drives, if you get them cold enough they can work for long enough to get away with things

I like that idea, as it should fix the overheating issue. However, the times that it actually has this malady aren't regular - it seems to happen more at night, but not every night. I could try putting it in the freezer when it does it though, and see if it works. If it is overheating, could it be a hardware issue then? I also noticed that my battery that I have in my phone does appear to have a slight dent near the bottom, and it is only happening when it is charging, so I am wondering if it could be a problem with the battery? When I pull the battery out after it has done this, the battery itself isn't that warm, but the phone is, so I'm thinking it isn't the battery, but does anyone else have any ideas?
I have the SM-T320 (Galaxy Tab Pro 8.4). About 5-6 months ago, I noticed that its battery life began to get much worse (used to last easily through the day, now only lasts a few hours of fairly light use). About two months ago it started suffering from random reboots at odd moments. I had been using one of the CM ROMs and tried others to see if I could solve the problem, with no success. Over the last few weeks the reboots have become so frequent that the tablet is unusable (random reboots every 10-15 minutes) and WiFi has also become unreliable -- the tablet seems to be able to "see" my home network, but can only occasionally get an IP address (even though the signal is strong and other devices have no problem).
Based on the fact that these symptoms have persisted through different ROMs, I strongly suspect it is a hardware issue.
I am wondering if anyone else has experienced these types of symptoms, and if so, how you solved the problem. I don't want to start opening up the tablet unless there is a good chance of success. Is this something a battery re-seat would fix?
Well the second Tab Pro I bought, after trashing the one I received for Christmas. Had a broken Anntena. No clue how that could have happened. As it's a very tiny Board that sits in the lower left Corner that has a Socket on one Side and the missing Gold Finger on the other. The upshot of that was I could only pretty much see the local Net. And Bluetooth had like Zero Range. Replacing that Part with the one from my first Tab Pro I managed to fix that.
As to the Battery, again the consensus here is that it's likely a somewhat lose Battery connection. So I would investigate those Threads for more Details.
Thank you. I did open up the case and re-seat the battery -- and the result was a boot loop, so now I'm not even able to assess the Wifi issues. I will have to spend some more time on it.
Might be a failed battery.

^ That thought crossed my mind as well. The behaviour I'm experiencing at the moment is as follows:
When I plug in the USB charger, I get a boot loop ("battery charging" icon followed by a few lines of text on the screen, followed by a "battery charging" icon, followed by a few lines of text on the screen, etc.) This happens even if I haven't tried to turn the tablet on.
By holding down the power key and the volume-down button I'm able to get to the "install custom ROM" screen but can't continue past it -- pressing any other button only gets me back into the reboot loop.
I found a few tips online that I'll try out later -- otherwise I'll have to decide whether it's worth it to buy a replacement battery (anyone have a good source?)
-The shortened battery life must be due to being used excessively maybe.....It is recommended that you factory reset the device every 6 months so that it doesn't get wasted like that.
-And the reboots is probably because the Memory being used too much as well, once a limit has been reached it reboots so that it doesn't blow up!
-The wifi issue is very common, the SMT320 has a problem connecting to poor connection wifi...make sure your speed is fast enough and is quite close enough to the router. If that doesn't help, try restarting your router, mostly works.
The boot loop is a very annoying thing, make sure you are not dirty flashing and do a clean one,i,e, wipe your system,data and cache and flash a simple and smooth rom....your choice.
Hope this helped in some way....

I have a bit of an update on this, for anyone following along or who finds this thread in the future. Re-seating the battery -- for a third time -- ended up solving the boot loop. The key was that I needed to leave the battery disconnected for an extended period of time (overnight). Things are mostly back to normal now, though the battery life is not what it used to be, so I may buy a replacement.
Tried rolling back to stock?
Had a lot of random reboots with cm, so I tried rolling back to a deodexed, deknoxed, debloated stock ROM.. problem dissapered... Then came back now after I've had the tab for 18 months. But only happens when battery is below 50% and screen light is fixed (turning on auto dimmed the screen a bit but stopped the reboots).
I have a T325.
Cheers!
A month or so ago my G3 started periodically restarting. As time went on it would restart more frequently, until the point where it was pretty much in a constant bootloop. After flashing a ton of roms with no different result i replaced the battery and it was fixed.... but only for a couple weeks. Since then I've burned through three OEM batteries, all to the point of being unusable. Curious as to what's causing this and whether i should spend money on another battery or cut my losses? Not sure if there's something wrong with my phone on a hardware level causing it or coincidence. I will add that the majority of the reboots happen while attempting to use gps (google maps). Also the phone will only work when charging right now, but soon it won't even work then, assuming the pattern continues.

When did they get produced? 2016 or 2017?
Hello , nice to meet you all. I am a new XDA user so apologies if i do any mistakes.
Yesterday, i got the 2 GB Ram variant of the LG G3 D855 from a relative. The phone almost works fine, except for two problems:
The first problem is that sometimes, the phone either locks up for about 3 seconds and shuts off (or maybe the screen shuts off? not sure), or either it completely reboots on it's own. I know, there is already information about this on the internet, however, some people say that it's a battery problem, some say it's an overheating problem. I am just confused. By the way, the issue happens no matter if the phone is charging or not. It also happens even when the phone isn't overheating, although it happens less. I may try a battery replacement, but unsure if it will fix it or not.
The second issue is, it's not really a critical issue, but it's just annoying. For some reason, especially when the phone overheats, the screen's right bottom side starts glitching (It also mostly happens on the home screen for some reason). And no, i don't mean flickering. Some glitchy lines appear at that portion of the display for about a millisecond and then goes away most of the time. Today the phone overheated when i was watching YT once and those lines appeared for like 5-10 seconds.
Also, i've noticed that the phone overheats a lot. Like, it gets quite hot sometimes.
I've already tried a factory reset, but it did not fix anything. The phone is running the stock Android Lollipop 5.0 firmware by the way. I did not want to take a risk trying to upgrade the phone to Marshmallow or install a custom ROM because of these problems.
I don't want to spend too much on the repairs of this phone since i've already got an another phone with almost the same specs as the LG G3. But i also want to use this phone. I just like it's design so much. Please tell me if it is worth getting it fixed and what i should do to get it fixed at the lowest cost possible. By the way, i don't understand much about the hardware of smartphones (I will get it repaired to an expert). So please, try to explain the problem as simple as you can do. Thank you and i wish you all a great day.
UPDATE: I've also noticed that the phone also has the screen flickering/disappearing issue.
However, asides from that, i've found an another issue too. So this evening, the phone was overheating too much so i decided to let it cool down a bit. So i closed the apps and put it into sleep mode. After about 5-10 seconds, the phone started doing REALLY LOUD tv static like noises. I immediately pulled the battery out, and i am afraid to turn on the phone because of that. I think the sound didn't come from the battery but i am still afraid.
I will bring the phone to a repair centre. But at this point, i don't know if it is worth getting it repaired. I am so confused. Is the phone dead or not? I've tried pulling the battery out and trying to boot the phne while it was getting charged (DON'T DO IT for your safety) and i get the "No battery" screen. I hope anyone that understands the hardware of this phone will help me. Thank you all.
