LG G4 getsuncomfortably, almost painfully, hot to hold? - G4 Q&A, Help & Troubleshooting

Often when I'm using my phone, the top half of it (near the camera) gets almost painful to hold due to the heat it's putting out. My phone has bootlooped before and got sent to LG to repair, but I'm still worried. I took the below screenshot of CPU-Z showing temps. These were after ~15 minutes of playing Clash Royale, with no case on, with the screen at 80% brightness.

As you can see, multiple sensors are reading over 70c - and believe me, it feels like it too. The only thing I have on it is a tempered glass screen protector, but this has also been an issue when it's just a plastic one.

Htc One X temperatures

Hey guys I have installed Battery Monitor and my phone is reporting too high temperatures when browsing internet - 42° C.
I played Qosmos on charger and temperature was 47°C. I am really disappointed with battery solution of HOX.
so, what are dangerous temperatures for our phone? I saw someone reported 55.. doest it damage battery?

No worry, mine went up to 63.8 °C. It is still working now...
More info @ HTC One X overheat up to 63.8 °C

yep most likely caused by overheat
50 and the clocks go down, 70 and the phone shuts itself off. My temps are basicly always +50 if im playing something or the phone is charging. Playing and charging rises the temps anywhere between 50 and 70... Just recovered from overheating shutdown, so yeah, overheating is indeed present with the ONE X...
Even browsing it gets hot, seems that stock browser heats more than dolphin, but I have to test it further. Temp+CPU shows 40C.

did you notice any gap between screen and metal lining on left side? some people said overheat may cause gap on it..

Now that you should mention it, i can definitely fit my fingernail between the body and the screen glass without any forcing or anything, resulting the case bending and it feels quite as i could just snap the glass off anytime i wanted. The glass also makes creaking noises, especially the bottom part. Scary stuff. Both sides of the screen and bottom corners show some flexing (disortion on the screen when medium pressure is applied) as well.
Beginning to reconsider whether my HOX is pristine or not, or could even the design of the model be flawed.
Good thing there is such thing as warranty.

yes it will be hard to put our hands on this
screen flex is associated with temps, its just not happening to all people depending on their usage and the state it come with out of box
if its hardware trait i can live with it but i prefer to have the flex on top of the screen rather than the sides lol
ill order HOX with screen flex on top lol
I was playing two flash videos yesterday on 3G and some surfing which was about 20 mins my battery before surfing was 40% by the time I realise how hot my phone was it dropped to 11%!!!!
I began to feel the phone get hot on both screen and back was so hot it almost burnt my finger. I understand T3 can get hot but not to the point of temperate of a hot kettle.
Setting the governor to Powersave only uses 2 CPU and save heat by alot even playing games. I use conservative, only uses 2 CPU mostly and its similar to on demand

i had this defect out of box on my first HOX never knew if it was caused by overheat but definitely it was imperfect out of box then screen was so loose you feel you want to pull it out
now ill test the new one which has no lamination imperfections so far
slowly though ill let the glue settle for a week first before starting the heavy stuff

good luck hamdir.. i read some of your post/comment regarding build quality and all this issue.. personally i think it take a lot of hope and belief that you'll get exactly what you want.. mine has gap as well but not so serious.. i think i can live with that and as long as it not getting widen.. except for this and some screen flex, my HOX has no problem..
My HOX is running around 38C on ARHD 3.1

is it downclockable yet?
anyway i'm definitely rooting this time
not taking any risks
CPU temperatuur
Is it also possible to measure the cpu temperature? I can only find the battery temperature. The highest temperature I measured was around 45* degrees. Sometimes the phone gets very hot in the right top corner. I have noticed at the left side of the phone there's a little gap, not so big that I could put my finger nail into it, but big enough for dust. At the top the gap between and the body is big enough for me to put my fingernail between the body and the screen, as far as I know that gap was there when I get the phone.
Anyway, I'll stick to this phone, if no dust gets underneath the screen I'm happy the way it is! I love this phone very much!! can't live without it!
My phone seems to get hot. The highest has been over 50C but it gets to over 45C when just browsing the internet with stock browser and not plugged in. This is with the newest 1.29.402.11 firmware
Is this normal for this phone?

Screen cracked overnight. How?

My girlfriend owns this phone, and put it on her dresser overnight. In the morning she found it in the exact same position, but there was a crack going horizontal along the screen, causing the bottom half to not work.
How does a phone crack like that overnight without being touched?
She claims that when using this phone that it often gets extremely hot to the touch when plugged in. Maybe that has something to do with it?
I've read that it is some kind of defect caused by heating and cooling cycles. or it could be that the battery itself puffed up and cracked your screen.
This Gorrila Glass fibre has these dealbreaker issues, it mostly happens due to the following reason : Upon gaming and/or charging, the upper half may get extremely hot and the lower half remains normal and takes relatively more time compared to the upper half to change its temperature. This regional temperature difference when sufficiently high causes tension and it gets cracked. DO NOT keep the phone at cool surface when it gets hot, heat is NOT the culprit, but the temperature difference is. You may keep it on soft cloth or a relatively warm place in future.

[Help] Display not responding

Alright guys, I need help. I purchased my device right at the launch day. After a month, I accidentally dropped it badly, and even after it had tempered glass at the time (didn't have bumper) the screen got cracked along with tampered glass. Device was new at the time and I didn't want to spend another 100 bucks for display. And it wasn't that much badly damaged either, so I could live with it.
Fast forwarding to this date, after 2-3 months, the device was lying on the bed. A minute before it was working completely fine, but now it's display is dead! It was just lying there and there was no damage done whatsoever.
LEDs, charging, everything works just as fine, but the display shows some random greenish strips at random places when I press power key to turn it on.
Now, earlier accident was not covered under warranty, but this is definitely not my fault. If I take it to care center, how can I convince them that the screen did not die because of accident and that the accident was 2 months before.
Kind regards
try to heat down and the bottom of the screen. sometimes helps for amoled display if there isn't any visual damage to actual screen under glass.

Like I said, there are 2-3 cracks on screen as well when it was dropped earlier.

Touchscreen responsiveness X screen protectors

Have been using this phone as a backup phone for a while and now I'm gonna give it to my grandfather. Since he is 79 years old, a bit careless, I purchased a screen protector.
It's the typical 0.3mm shatter proof 9h but the problem is: I can barely pull the notification bar and the phone just feel like not responding at all.
You must press harder on the screen, at times with two fingers running down the screen to pull the notifications, typing is a nightmare. Since it completely lost the sensitivity, it feels like the phone is slow or freezing up but it's not the case. I'm pretty sure if I take the screen protector off it comes back to normal. Funny enough, if you run a touchscreen test, it works just fine by just lightly touching it.
The touchscreen is awesome without it, I used to play some minor games on this phone. It was my daily phone for walking and listening to music, I switched back to my Nokia 930 because I don't think my grandpa would be able to use a Windows Phone lol.
Has anyone experienced this kind of issue before? Don't think the phone will last long naked just like his Moto G4. (two weeks with a shattered screen then completely dead)
Should I purchase another screen protector?

Screen defective, white halo

Hi, since I got up this morning the screen of my Note 10.1 has a white halo on it.
Do you think it's a hardware fault? New screens sadly cost double what a used note 10.1 would cost, but maybe its just a loose connector?
Its flickering and getting worse the more contrast it has to display.
Anyone have seen something like this before
That must be a mechanical defect. Probably someone sat or laid in the Note. One of the two glass plates or the rear polarizer have been bent in a concave ir convex shape.
Can also be caused by excessive heat, like on the small lcd in my car dashboard, where a similar phenomenon has started to occur more and more often and in a more severe manner recently, caused by sun exposure and the car's heater and disapperaing when cooling down.
Or delamination of the gapless touchscreen. Now there is a gap on the outsides.
Thx for the reply. I have the tablet hanging on the wall, using it as an interface for my home assistant, so the screen is on pretty much 24/7.
Therefore i can't really imagine that there was too much pressure on the screen at any time and heating up could've maybe happened if it locked up during the night, but that hasn't really happend ever and in the morining it was running just normal, except for the screen. The sun can't really get to it either.
Well good thing is the problem fixed itself. The affected area started getting smaller and smaller and the effect also lessend over time. About 2-3 days it took.
Maybe there was some moisture inside it or something idk
Something had snapped or bent from and then back into shape.
I'd suggest that it was heat related, bootlooping while charging,probably.
I could trace such with the history of my battery monitor app(complete with temps and for as long as i set the the range), but the course graph of the system battery monitor could have have provided hints, too. But that's long gone now.
My very first Android device was a tablet, that once too many went into a bootloop. During charging AND during the time of the exploding Galaxy Notes. The whole surface (metal and glass) had the same temperature, no more hotspots, and was almost too hot to touch(50c at least).
I'm not sure whether the screen was discolored, there was only the small boot logo on black, but i immediately threw the thing into the bin outside, display still glowing in the dark.
This is really dangerous when the device is connected to the mains and the surroundings not fire resistant.
In the meantime the battery of my P605 started to blow up.
Middle of backside and even touchscreen are bent outwards.
But the display is still fine, though this kind of malfunction could happen to me later.
Will get a replacement battery. The original one from 2013 still has more than 50% capacity, but is much thicker now...
