Today...the unthinkable happened.
I dropped my phone from about 3 feet!
Luckily, I had a case on it, and there wasn't any damage to it...cosmetically. When I went to make sure there wasn't any internal damage, I tried a SetCPU stress test, a quadrant benchmark, an antutu benchmark, and a Linpack benchmark.
SetCPU was stable, quadrant was higher than before, and linpack was about the same. However, when I got to Antutu, my score was about 1000 less than before.
Before, I got RAM=~950, CPU Integer=~1825, and CPU Float=~1427. However, now I get RAM = ~700, CPU Integer = ~1350, and Cpu Float = ~1150. Everything else was about the same.
I should also note that at the time of testing, the phone was pretty hot (100 degrees Fahrenheit). The original scores were achieved on 80-90 degrees. Would you say this is a coincidence (and it was caused by heat), or hardware damage?
Coincidence.

I can run quadrant twice, doing nothing between tests but push the start test button, and get two completely different scores.
It was the heat after all. I let it cool down to 80 degrees fahrenheit, and it's back to the normal 6000+ scores. I feel so relieved now.
Did you pick up all the binary bits from the floor? Maybe some bits fell out so phone is still busy looking for the missing bits.

You're fine. Luckily the phone was ok. I think I would crap my pants. What case are you using?

It has this awesome silicon layer that absorbs the impact.

My HTC One M8 fell by 2 feet. On the corner; has hard shell.
After this, the phone was very slow. The kind of slowliness I do not try to dig, and just reboot. Reboot took over 5mn. Then, phone kept screen off; I knew the phone was working: received a phone call; power button was working fine because long press on it could light the flash (Xposed customisation); volume buttons also work fine. After long press power+volume, I could reboot, and during reboot, the screen came one again. Screen could turn on each time I rebooted. After boot was completed, if I let screen timeout and go of, no way to turn it on again.
If I don't let screen go off, and keep it busy, and try to use my phone:
- background image animation lags a lot
- tactile screen works almost fine
- apps are responsive, but viewing on screen lags a lot.
- all system tools report a good iddle time, low load, and available CPU and RAM.
- the whole phone behaves like when it's over-heating, but temperature was low. The problem was perfectly reproductable during several hours.
- system behavior could also be compared toa computer working with full software rendering, without any hardware acceleration. CPU and RAM feel good, CPU reports iddle time, but graphics lag.
Power button was working fine on hardware side because i could use it to force reboot, and switch light on. But power button could not turn screen on. Hardware of screen was working fine, because after reboot, i could get a working screen. But, how could a simple fall produce a software issue ?
I had replaced my battery myself some time ago; so, I know that I have not glued it the way it's done at the manufactory; also I had to break tapes, and could not replace them. I have placed all screws correctly. My thoughts have been:
- CPU or GPU are not strictly overheating, but, maybe their physical connection to heat sink is bad
- maybe the battery moved a bit, and is pressing against something, deforming a heat connection, or pressing hard against a sensible component (and alter it's value)
- inertia could have pulled a cable out of it's plug; maybe there is a bad connection somewhere. Power lines had poor connexion providing too little current (or undervoltage); data line disconnected.
If the GPU is partly broken, system can fall back in software rendering, and a broken GPU may not imply a loss of screen; just switching to an other video mode.
After leaving the phone off for 1h, and rebooting 12 times, phone works perfectly fine again.
There is no way this could be a software issue.
It was a hardware issue, that had very little impact on something, and fixed itself after some hours.
May not be GPU itself, but really thinck it was "video related".
I got this White HTC One X from a friend who dropped it in the waters.
It boots up just fine, the digitizer works, as well as... partially... the screen
Now i got the data from it, so mission accomplished in terms of data loss. He gave it to me for free so i rooted it with the bad screen.
So now i have this rooted phone running latest stock ROM.
The screen's brightness is too low even though the brightness settings is set to maximum. After a hellova lot of testing i found out that when the device is cold, the brightness increases when i turn the screen on. And when the processor is running (ie opening an app, or rendering animations), the screen's brightness starts to get lower and lower until it just completely shuts off.
What i did was put it in the freezer to make it REALLY cold, and it works just fine for like 5 minutes until the CPU gets hot again and the screen turns black.
I tore it down, and changed the screen, but the problem is still there, so it must be some part of the motherboard.
I won't change all the motherboard because honestly i don't want to spend that much money on something older than my nexus 4
So if anyone can tell me what part exactly is responsible for the brightness IN THE MOTHERBOARD, so that i can find a way to keep it cold, it'll be very much appreciated.
PS: I can see and control everything from PC too when the screen shuts off... so i can still practically try and do anything with it. Also, the actual LCD screen is cracked and black on it's right and bottom half, and it's currently "half open" (ie i can see the Nvidia CPU, and the vibration motor under the screen)
I am thinking to buy the phone but I saw some posts there are some heat issues. So what is the problem besides the phone getting too hot? Is it shuting down when it gets too hot or get really laggy? Is there any other problem when heated except it gets really hot?

I haven't experienced any heat issues. I have yet to feel my g3 get warm Tbh.
Others (not sure which model) have reported issues with heat, to the point that it causes the device to throttle the brightness down. Again haven't experienced this on my at&t model.

Thanks for the reply, someone with issues ?
Same here not felt it get warm even watching video.
When the phone gets hot several things happen.
1) The CPU is clocked down to help lower heat
2) Brightness is capped to help lower heat
3) If the phone continues to get too hot (usually when its already hot and you then start to play a really intense game, or benchmark the phone may shut itself down.
People complained a lot with the Korean model but I haven't seen anyone with a US model complain. Maybe the type of person that waits is less likely to be a phone gamer? They may have actually tweaked it so it doesn't activate as quickly or harshly. I do know some people disabled it on the Korean model. I haven't heard of anything bad happening but those few people may have felt dumb if it destroyed their phone and not posted that it did...
I have no heating problem with my lg g3 international D855 16gb model, even during quadrant test or playing games.

Define an actual temperature for hot.
I disabled the thermal protection on my AT&T version and yes, I've felt it get quite hot while playing Final Fantasy 6. The heat radiated mainly through the metal power button but the entire top half of the device got pretty hot. Didn't bother me all that much tho, as I've had other devices get hot like that in the past.
I use exposed app CPU temp my g3 sits at about 30c and 45c which is normal temps and about 50ish whith thermal protection on disabled.
what heat issue

My girlfriend picked this up yesterday and this is happening to her G3. Not playing games though, just browsing the internet/reading an article. It makes no sense to me. How can you take control over that? She doesn't want to root the phone.
But yeah, just reading something or even looking at Facebook, the phone gets way too hot.
I picked up the Verizon version yesterday. It's gotten pretty warm around the power button a few times for me also. Typically not bad or what I would consider unusual with one or two exceptions.
My G3 (UK) go very very hot yesterday when I was on the train playing a graphically intensive game.
It shut itself down and then refused to turn on again. Ever.
I tried everything all night but no joy. I got a replacement handset today.
I'm sure it was because of the overheating that the phone malfunctioned. Without knowing exactly what has happened to it the timing is too coincidental for it to be random hardware failure. It was SUPER hot!

This is strange. Does the kernel not shut the phone down before it "fries" the SOC?,unless the throttling temps are too high? Wonder if this is linked to the display flickering problem myself and another poster had.

Funny you mention display flickering. I had that about 2 weeks ago. The display started flickering really badly, like nothing I've ever seen on any Android device, and I needed to pull the battery to reset. It didn't boot straight away either, it had to cool down a bit.

this.
all phones get warm if you are on it for an extended period of time, surfing (using data), gaming etc etc screen on for long periods of time. those saying they can game and not have heat are lying to you. phone gets warm when screen is on for extended period of time and by phone I mean any phone

Yeah, i had a flickering display which didnt go away.I returned that phone. Another poster yesterday had the same issue.Im wondering if the GPU is frying itself? Although the GPU does throttle as well as the CPU. Running Antutu I would get 60+deg C maybe playing a game for an extended period of time for example is causing damage? Just a theory.
I checked out a video with the G3 being pulled apart. Right under the power button, is a silver rectangular(ish) component. Can someone tell me what that part is?
I'd just like to understand the source of the heat.
Thanks in advance.
The source of the heat is your CPU which resides under the power button more of less. You will also notice that the display gets hot on the front top half. This isn't necessarily normal, were you doing anything CPU intensive? (Gaming, recording long 4k videos, streaming 2k videos etc...?) It won't hurt your phone but it shouldn't be hot to the touch but instead 'warm'
Thanks for your answer.
I'm finding that videoing for 2 minutes really starts making it hot.
I'm not rooted (yet) running 10j with a 16gb aus version.
Any suggestions would be appreciated. I'm not going to root until Android L has been out long enough to "settle" down.
I had overheat issue with my first G3, it would get really damn hot, took it back for a replacement, I suggest that, if you can.
Mine was shutting down due to temp and 100% stock, if they wont replace due to overheat then tell them it shuts down which it probably will eventually if it is that hot.
Another option is try a different launcher and disable any apps or background stuff in Settings/Apps/etc that you dont need then try video again.
Thanks for the suggestion. I could take it back but it would be my third g3. I suspect that its the 2gb of ram which is the issue. Because I live in Aus we only have a 16gb 855 version. I suspect that even with a replaced phone I would still have the heat. Its not enough to shut the phone down and not enough that I can't touch it. I stick with my original reasons for getting a g3 - best hardware I could get with a limit to the bloatware (ie not s5). I don't think I could handle the 5.9" nexus. All I can say is, if you can't handle the heat, get into the kitchen (and sample the ROM menu).
Thanks for your help

I do believe I fixed my bootloop caused by the CPU. I need some feedback though. Anyone want to download Cpu Temperature from google play and report back with their IDLE temp? I have not done any extensive testing yet such as stress tests etc since I'm still letting my battery charge up. But would like to know what your IDLE temps are compared to mine. I was faced with the dreaded bootloop that happened literally out of nowhere. After doing this fix I have had my phone sitting and charging for about 30 minutes now as where before I couldn't even reach the red Verizon boot screen without keeping it in the freezer for 10 minutes and then powering on only to be able to use it for two minutes. My IDLE temp with screen on at 20% brightness is 29c

To add to the above I then downloaded StabilityTest (ROOT optional) from the google play store to stress test the CPU and ran the classic test for exactly five minutes and then switched directly back to Cpu Temerature at the CPU temp was at 43c so if anyone could also run that test for five minutes on the classic test and report back with their CPU temp I'd appreciate that too.

Just an update, Has been a few hours now and phone is still working after playing angry birds, taking pictures and videos, using facebook and messenger, watching youtube 1080 60fps, and keeping screen at 100% brightness my average IDLE CPU temp is hovering around 35-37c

(attempt the following fix at your own risk I am not responsible for any damages to your phone or property or anyones else's property)
Checking back in. Turns out to be a partial fix. Under normal phone use it works fine. The problem comes when you do a factory reset. The way I fixed mine was I took the phone apart, Took the motherboard out and on the center back of the mother board that faces towards the screen is a piece of thermal tape (very thin) I then took some polished copper and hammered it out to about the thickness of half of a dime. and then cleaned and polished the copper again. (make sure it is pure copper not a penny as most these days aren't 100% copper) Then use some arctic silver 5 thermal paste or even better a NON conductive thermal paste... Take the thin thermal tape off of the processor on the motherboard. Then apply thermal paste on the processor covering entire processor about half the thickness of a dime. Next take your copper which should be at least the size of the processor and stick it onto the processor. Then put everything back together. If your phone is in the middle of a factory reset put it in the freezer between two paper towels for 10 minutes then turn it on and complete factory reset with it still laying in freezer between paper towels. I can't guarantee this will work for others but this is what worked for me. The phone just still gets too hot during a factory reset. I got the idea for this from the following video on youtube and then added my own little spin on it in places.

Thank you. No one answered me in the International thread, but it looks like you did the same thing I did and factory reset f* everything up for you too...
Anyway, do you have a blue spot on screen due to pressure?

Unfortunately this didn't work for me wish it did though..
I got the bootloop after owning my G4 for about 18 months. Tried all the software fixes, heating, cooling etc, and got precisely nowhere. However, dismantling the phone, and heating the CPU with a heat gun on low power, followed by a bit of pressure, then reassembling with some thermal grease on the core, has resurrected the phone with no data loss. (Still going to buy a new phone though).
Only problems are - I constantly get a message saying "Unfortunately, Apps Update has stopped." This pops up every time I use the phone, change a screen, open an app etc. and I cannot find a way to fix it.
- LG backup seems to have stopped working properly as well - it won't perform an update, although it does prepare one, and the buttons have decided to label themselves in dots (presumably Korean or something) rather than English scrip, so it is difficult to see what each button does. However, I have backed up all my data through LG Bridge.
- battery life seems awful - but this seems to be a Marshmallow problem, rather than the phone.
- I'm getting a new one because they're cheap, and also I'll have a UK version so I can root, unlock etc. etc.
Same miserable story here. But I don't know how to disassemble phones so I sent it to a friend and he told me its a general problem with the LG G series where the CPU soldering detaches from the mainboard. Every few days I have to sent it back to fix it again, such a pain in the ***...
Mine was as good as a new so I won't buy any LG high-end product after this one ever again.

Just had mine which was out of warranty fixed by LG free after I contacted them, so if you own a bootlooping VS986, there's still hope for it.
