Unable to brighten due to temperature increase. Try again later.

Anyone else get the error message "Unable to brighten due to temperature increase. Try again later." yet? I've noticed it once while browsing on my phone and attempting to increase the phones brightness, at which point it maxed out at around 66% while displaying this error. The phone did not seem HOT in my hands, just warm. Was able to reproduce this issue by running the Antutu benchmarks multiple times and then changing brightness.
Am running the stock Rogers E971 ROM. There is no case currently surrounding the phone (although I can assume a case would just further this issue). A factory wipe did not make a difference.
Anyone else able to reproduce this?

The max level depends on the battery temperature.
When im outside, battery shows 32~36C and im able to set the maximum brightness level.
But for indoor use, cant go above 63%. Current temperature is 40C
I think it doesn't feels hot cause of the back cover glass.
Galaxy S3 feels much hotter.

you think that would be 'normal' behavior though? its not an issue I had with my Galaxy S2 and it seems like bad engineering / design if a device that is running at its intended clock speeds in a normal environment is heating up. I guess ill try calling up LG when I get some free time to see what they have to say about this.

I think 40C is a normal temp, so i guess the reason of limitation is the battery itself.
LG said Optimus G got next-gen Li-Pol battery or something like that. Probably it doesn't run good on high temperatures.
Nope, thats an issue but im not affected cause my default bright level is 40%

Solved!
From today we have a permanent working solution to the problem ! Tweakers and Optimizers released a free app called LGBrightnessPatcher https://play.google.com/store/apps/d...3NwYXRjaGVyIl0. that surely and permanently solves the issue.
Many thanks and respect to the developers

G3 bricked?

Argg!
I was playing a game on my G3 (UK 16GB) and it got SUPER hot!
It turned off and now will not turn back on. It's stuck on the LG initial splash screen.
I've done all the usual (remove battery, power + volume down, recharge battery etc) but I'm stuck.
Any suggestions before I return it today?
I'm sad ?

I would say return it man.

Has the phone called back down yet?
Don't try to turn it on until its cooled down.
Take the battery out and leave the back door off for half hour then try again.
Just so we know, did you turn Thermal Throttling off in the hidden menu? If so, this is a prime example of why I have been telling people not to do this.

Hey Lenny,
I didn't turn Thermal Throttling off. And I would also advise people to not do that.
I've just returned from CPW with a brand new handset! FYI the 28 day replacement policy starts from the day you receive the phone so I was still covered. Just!
I did all the things you suggest. It was stone cold and it still wouldn't get past the LG boot screen. Also the little sparkly animation on the LG letters wasn't playing which suggests it borks out very early on in the boot sequence.
I really hope we don't start to see this more.
Fingers crossed!

Good luck with the new phone then.

alright now im starting to worry frying my device. Last time i ran antutu battery test it runs hot. The highest temp that i got is 41.8c on battery temp. It normally runs at 34 to 36 if im playing with it but wont go over 40.. Do you think my device is also running too hot?

anything below 50 degrees is not really anything to worry about.

Thats cool,my G3s ran Antutu at 60+deg C and idled at 45-58. Your temps make me wonder if i had faulty units (i had 2 as the first one had a fault).
Edit, just read you said battery temp? You need to measure CPU temp not battery.

That is what i wanted to know... Is there any apps out there that can measure cpu temp accurately? Does our cpu have built in sensor? Batt is heating upto 40c,,, what more in cpu... I wanted to run a full test again after fully charge.

Try the app made by Mooncakes on the play store. Just search for CPU temperature its free and graphs temps v cpu usage and speed.

Is the overheating caused by the 4.4.2 update? will it be fixed when Android L come?

I read many other android device users android device on 4.4.2 was overheating. Maybe thats the cause of it?

No,its not. Its because the CPU and GPU are having to work harder to render the QHD display,therefore there more heat.

There is no such thing as over heating. People are just crying about stuff.

I wouldn't say over heating, more like generating heat, every LG phone I've had got hot, I had the LG g pro when using gps it reach 120 degrees, that's why I returned this phone gave me sweaty hands

This def doesn't get as hot as the S4, Note 3, or S5 that I've recently had. It even stays cooler than the G2 I had also.

How long were you using the GPS, when it got 120 degree?

I see 170* plus sometimes. I use a Xposed add in to display CPU temp in status bar. GPS makes it hot because screen is always on. Lowering the brightness helps, but when using the GPS on a longer trip I try and aim some AC at it and then it cools down to 120-130*. My previous phone Note 3 did the same thing although I think the LG G3 gets a little hotter. Sure I worry about heat damaging components that's why I monitor CPU temp through Xposed.

I use GPS mapping apps all the time and don't keep the screen on. Google maps won't query location when the screen is off unless you run something else like Locus in the background to keep the tracking active. Never have any issues with heat.

I'm American also but I've gotten in the habit of using metric for phone temps since being on XDA lol.
I think you're ok. I use the same module and every G3 I tested so far (4) have shown up to 80 C (176 F) right after a reboot. It cools down quickly tho.

Hey, I underclocked the cpu with setcpu to 1267mhz, but it still heats like it normally do. do you think it could be battery problem?

[Q] LG G3 thermal mitigation daemon problems!!!

I have turned High temperature property OFF to ON, and everything works fine. no lag, no problems. I can run antutu 5 four times in a row (with 100% brightness) without getting the phone ridiculously hot, no overheating probs none so ever. Getting scores from 34 000 - 37 000
BUT when i turn the thermal mitigation daemon ON, the problems with overheating comes along with it. I have tested to run antutu 5 several times with the screen brightness as low as 10% and the phone still gets stuck at 21% of full test in antutu 5 (CPU testing mode), showing a message of overheating and then turn the G3 off. The thing is that the phone still doesnt feel that warm at all.
I'm starting to smell software issues....
Anyone having the same issues? or tips on what I can do to resolve this?.

This is a know issue of this "mod"

These "mods" are only meant for testing and not for daily use. There's a reason why the phones are shipped without them and that's to stop them from overheating.

Disable them again as they are useless anyway

You don't feel it, but if you monitor the CPU I believe it reaches 80°C faster than the heat can dissipate at the back of frame and that causes the phone to automatically shut off before the CPU gets fried. Happens to mine too buddy. It works fine as long as you don't run any benchmark. Never had it shut off with the thermal daemon ON while doing normal stuff like gaming. Don't ever play demanding stuff while charging either.

I have suffering from the mysterious heating, did anyone had this problem?

Hello everyone, this is my first post.
My phone is LG D855, bought from two years ago.
I know the S801 will running at 2.5ghz as its needed, which will increase the cpu temperature temporary in an acceptable range.
Therefore, I start thinking the problem about the CPU. Then I used the kernel auditor to force down the frequency and the voltage as low as possible.
But the situation still doesn't changed!! And the most weird part is that heating is not continuously but it will burn up suddenly for no reason and no any sign. The CPU temp has been reached around 62-70 degrees, and YES! You got that right, it is hot like I am using the laptop processor on my phone.
The things I had tried before :
Flashed many roms ( Including various stock roms )
Replaced a few new batteries ( Some of those was already dead )
Changing the CPU frequency and voltage ( Minimum 268MHz @650mv , Maximum 1497MHz @840mv)
Force to turn multi-cores off to 2-3 Cores
Apply some heat diffuser tape inside the phone ( Sorry, I don't know the name of that thing, it is black and the iPhone used it too)
After all these messing
Nothings has changed! Yeah! This phone is driving me crazy!
Imagine that something like a fireball burning in your pocket?
I had been suffering from LG G4's CPU issue enough. I was using the G3 before I had the G4
Because of the quality of the G4's camera, and in that time, my G3 just work very well. So I decided to buy G4 at that moment. But the result just told me I had made a wrong decision.
I just go back to G3 since my G4 was died, and now the G3 works very bad...
I am really disappointed on all LG's phones. I will never go there again.

Yeah first of all this is a messed up phone all over place. Heat and CPU throttling because of heat brings lag to phone. 62-70 Celsius us usually became normal for this phone, in summer it becomes worse. I know some people will say install this install that but there is no way. If you have enough money sell this and buy a new phone but if you don't have money try to apply thermal paste to your phone there is instructions in general section about that. Good luck.

Thanks for the suggestion, but the heat are still there even if I apply some paste on the die, doesn't it?
There seems the problem is just not about the hot air flow won't get out from the device, it's the CPU draining my battery as well, which is mean the heating is just one of those problems. The battery problem is can't be ignored too. When I noticed the phone start burning, I will take it out from the pocket and observe its battery status. And the result is very incredible, it had lost 10% battery life in just 10 minutes!
I had enough money to buy a new one, but just don't want to waste any money on phones until this one die.
I am not a power user or even not a gamer anymore, just used my phone for web surfing or chatting with friends. Although s801 is just way too much performance for me to doing those ordinary tasks, I still keep it for the QHD screen. Those cheap phones, yes, they are already matched my requirement but not included the screen.

People say thermal paste help them to get down heat. The problem is that G3 doesn't have any thermal paste to make cpu cool down. Cpu heat directly goes to metal surface so the phone can't cool down itself and sometimes it's so hard to touch it. If you have some hand skill try to apply thermal paste there are enough instructions and discussion in that thread. Also about battery, G3 battery is awful, it gets broken easily phone keeps reboot itself when battery dies, because it has QHD screen battery goes down easily. Make sure some apps don't stuck in background and eat battery. Sometimes when phone in pocket and idle it gets hot because some apps keeps working in background so make phone hot and eats battery.

Hi, I did a research about the mod that applying the thermal compound on the CPU die.
Many of people say that is effective to reduce the temperature at least 10 to 20 degrees after they tried that on their G3. Since the thermal paste is not pricey, so I can give it a try. I will try to do anything I can to calm this baby down. And in the future, I will never fall into the LG's phones trap again. (by the way the G5 looks very nice, but it still not my cup of tea.)

G3 is the only LG phone I've heard with heat issues.
My old G2 (which is just as fast) never overheated and always remained cool to the touch.
With that said, I just did the thermal pad mod yesterday.
Used some fujipoly 11 W/mK 0.5mm and it worked wonders.
Idle is 35-40C
Normal temps are 45-55C
One day into it and the phone is cool to the touch no matter what I toss at it.
Do the mod bro. 15-20C cooler temps across the board also makes a noticable boost in performance and smoothness.
I really enjoy using the phone like this

D855 CTT mod
1. Thermal paste.
2. CTT Mod : http://forum.xda-developers.com/lg-g3/development/wip-2-12-ctt-mod-marshmallow-testers-g3-t3313870.

I had the same problem. I found a youtube video, watched how to break the phone down, and applied the paste. It was important to use a generous (not an insane amount though) bead to ensure contact with the cpu and the frame. The phone temp at idle dropped ~15 to 20 degrees, and it never shuts down from overheating anymore. I can overclock the cpu with a custom kernel now, no heating issues at all.
