Android causing damage?

When running Android, my phone gets hot. I also know that when it gets hot, the phone will shut down when I open/close the keyboard, and later have this behavior even when the phone is cool. I am wondering if the increase in heat may be damaging the internals of the Tilt 2? I am about to get my third one in from ATT, as I had to send my first and current one back because of this.
I am in no way blaming the devs or anything, I know I run Android at my own risk. I am just curious if anyone else has had a similar problem or knows of a solution/other reason for this behavior.

Do you only have this behavior in Android...? If so, you probably have no grounds for replacing the phone...

Which version are you running?
The Blazn package overclocks the CPU by default, which could cause it to get warmer than you are used to in WinMo.
Also, the power savings aren't totally finished, so again it will more than likely run warmer than Windows.
Did you disable the Auto Backlight Control under WinMo? Failing to do that can cause the backlight to stay on all the time which will draw a fair amount of power (and generate heat).
If it's getting really hot then I would think there is something else at fault, but you need to provide more info.

yeah shouldnt be getting "hot." maybe a little warm. and i would suggest taking it out of any cases you have it in while running droid or overclocking.

if any thing its the battery thats getting hot....the battery may be damaged if anything and you may loose some of your capacity to charge...so change the battery...idk but that maybe the issue...if it starts to get hot you should reboot and dont let it run hot for a long period of time...or maybe its time for another phone one too many drops...idk only some suggestions

I used to have this, its caused by the battery being loose in the craddle.

The heat Issue?

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

Do we have any official documentation from Qualcomm on how hot the cpu can safely be?

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.

[Q]Known problems of LG G3

I am thinking about buying a new G3, Is there any chronical issues-problems of LG G3?
Like dust in screen or speaker blow or any hardware malfunction

Don't be completly discouraged when reading this, as this is just my list of CONs for this phone.
Here's some of the issues i've had on my G3 from the very minute my phone left the box:
1. The phone has a locked bootloader, So don't expect any custom roms or kernels anytime soon.
2. This phone gets very hot for almost no explainable reason all the time doing small tasks like browsing the web.
3. WiFi (and maby LTE??) are REALLY slow in comparison to every other phone i've owned in recent years (sometimes web pages even freeze while loading).
4. The stock web browser kills my battery in about 2-3 hours from a full charge on 0% brightness because of LGs stock webbrowser sandbox security.
5. I get constant "connection timed out" errors while trying to stream many online videos using the stock web browser.
6. CPU doesn't hit max speed on this device without messing with thermal options.
7. The phone is very laggy & slow on my version (10b), I don't know how other versions are though.
8. The glass started falling out of my first G3 (around the edges) and i had to exchange for a new one because of this. (my new one did this too but only at the bottom and i just live with it)
9. VERY poor color & contrast when the screen brightness is turned way up (looks good at low brightness though).
10. My left headphone buzzes while the CPU is under load while no audio is playing, Once the CPU load stops or once a song or movie starts playing the buzzing stops (tested with 2 sets of headphones, both buzz but apparently some other users say there are headphones that don't do this).
11. + some other small things.
Probly the most complained about things are these:
1. lag
2. overheating
3. physical cracks develop usually around the ir blaster or mic

Im not having any lag issues, im on 10i though, my phone is yet to get hot too, not sure why this is, im very very happy with mine at this stage, only downside is the locked bootloader.

No issues here, the heat issue was fixed with software updates from what I have seen. I have no issues with heat on mine. The contrast can be fixed or made a little better in the accessibility menu. I've had 3 G3's and none of them had the screen fall out or develop a crack around the frame. (I think that was a limited issue)
I bought my first G3 back in early June and it was fine until I dropped it off my balcony. My Att G3 hasn't had any issues either. The signal issue listed above is more of s perception thing. My F460S (G3 Prime) only has 4 bars in its cell service instead of 5-6 that others have. So basically if I have 3 bars its like having 4-5 and my connection has always been fine. I think that some of the issues are exaggerated on this phone but that's just from what I have seen after owning a G3 since it launched more or less.

No lag, no heating.. Just two troubles.. 1.LG software.. Phone is so slow and heavy. 2. Locked bootloader..no LG software replacement.

If you want a g3 with an unlocked bootloader, buy it from T-Mobile. I have mine rooted recoveried, and have installed a very nice custom rom/kernel. This is by far my favorite Android yet.

As far as Amb669's list goes we haven't seen any of those problems. My wife and I have had our Verizon G3's for a couple of weeks now (not exactly a long time) with zero issues.
My WiFi speed in particular is Amazing.
Keep in mind two very important caveats:
My wife and I almost certainly use our G3's differently than Amb669 (and each other) - not better or worse just different.
It's possible that if we used our G3's in the same way as Amb669 does we might experience similar problems.
Our G3's were purchased recently - our phones may be from a later batch that has had issues corrected.
Our G3's firmware/software could also be different/improved.
I LOVE this phone and wouldn't hesitate to recommend it to others.

I have some problems with my G3 too, it's too slow... i prefer my Old Xperia ZQ, maybe it's a Software Problem ? and my G3 gets so hot too... damit i'm disappointed.. there are something that could do ?? i already resete it but still the same thing.

I have not encountered ANY of these issues, except for the heat issue.. But seriously it doesn't get that hot? Mine gets to about 55 degrees Celcius and that's max.. (I have the int. Version though)
On the other hand I do agree on the fact that the colours could be better on high brightness but hey, it's not a Samsung AMOLED display like the S5
For me the LG G3 is a stylish, fast, and amazing phone that offers everything I need :good:

Check this for one of such problem I do have - http://forum.xda-developers.com/lg-g3/help/lg-g3-d855-faulty-buzzing-interference-t2899373

Can anyone here please confirm whether this used G3 is in good condition?

So I've just got this used G3 for about half the retail price with half a year warranty time remaining.
Specs: 16GB Storage, 2GB RAM, OS upped to Android 5.0 Lolipop
After spending some time playing around with the unit without a sim card, I came across some less fun facts about this G3 which are as following:
1. The unit gets warm/hot pretty easily under normal use, an app called CPUZ detects that some temps would go up to 70*celcius.
2. Battery drains a bit to fast under normal use.
3. Sometimes brightness can't be set past 90 with a warning message saying something like "brightness can't go 100% due to high temp" pops out.
4. Camera would sometimes crash and render unusable before the system is restarted.
5. It's either I didn't know how to properly use the camera (but I believe I did cause I used it the way people demonstrate it over the internet) or the autofocus no longer works the way it should as it always fails to freeze moving objects during a capture. Not to mention grainy in low light.
6. When brightness is set to Auto, the screen would turn way to dim. It seems as though it's nothing like an ambient light sensor because the brightness won't turn brighter nor dimmer in any light situations.
7. There are some seemingly minor scratches on the laser and the camera, I would like to know if they affect some performance.
That's it for now, everything else seems to be in great condition. Do you guys think I should use the remaining official warranty time to RMA it while still can?
Thank you for reading!

If you haven't done a factory reset yet, I suggest you do so. If nothing changes, no doubt your phone has major issues, RMA.

I have done a couple of times of factory resets and nothing changed I'm afraid
Anyway I would like some detail on the major issues my unit has so I might be able to detect if certain defects still present on the replacement unit.
Thank you!

Brought my G3 to LG Cust Service and the LG guy said that the high temp is normal(my G3's idle temp is around 55-60 Celsius even after factory reset) and today I just got contacted by the LG guy again telling me that he already reviewed my G3 by comparing it with another G3 of same model at his office, he told me that G3 are that hot, he wanted me to come and see for myself.
Could it be because the other G3 he uses to compare my G3 with was of the same bad batch? because many reviews of G3 on the net seem to be very positive and there are barely any mentioning about high temp

Random reboots and screen glitching

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.
