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

[Q] "High temperature" auto-dimming phone.

So I've got the E970 (AT&T's model) and it apparently does not light staying cooled down.
When doing modest gaming, and even surfing the web I get this lovely message:
"Unable to brighten more due to high temperature. Try again later."
That seems rather depressing. Considering the phone is great. The screen, that is wonderful and I like being able to have my screen maxed while charging or whenever. If the screen is pretty, I want to exploit that, after all.
One thing I've noticed, This thing is constantly sucking a gig of RAM, even when idle.
Anywho, has anyone else experienced the heat issue? This is the second phone I've received with the same issues. I'm trying all methods possible to keep it and fix this issue rather than just taking this one back again and getting a One X+
Seriously, any advice or direction would be pretty awesome.

IMHO, Heat should be normal for quad-core mobile devices. My Tegra 3 tablet, although all plastic, heats up when using. My LGOG does heat up in heavy use. The reason of the screen brightness threshold is to reduce the increase in temp. If you're rooted, you can also notice the clockspeed of the CPU cores are also decreased to 1.18gHz when it reach a certain temperature (about 40-50 degrees).
On another note, this should be posted in the Q&A Section

Moved to Q&A

Erm... Isn't 28nm s4 pro not supposed to heat up that much? My tegra 3 1.7ghz only scales max of 35C when browsing... Maybe getting optimus g for fun but battery life and temp is so horrible...

Nah actually its not like korean SGS3.
Didnt measure the temp on sgs3, but it feels much hotter for sure.

My phone gives me this message on a regular basis, even under relatively light use. I'm glad that there are features implemented to protect the CPU and other hardware from overheating, but good grief, this gets rather annoying - rather quickly. I haven't paid too much attention to my OS and software to notice if I'm also burning a gig of RAM at all times, but that wouldn't be terribly surprising. I'm running a lot of background stuff, ADW Launcher EX, system monitors that I never check, custom lock screen, so on and so forth...
I will say that I didn't have a single heat warning until I rooted and unlocked the phone however. Perhaps it's completely unrelated as Gabby is saying the CPU will throttle on it's own in rooted devices, but just something I noticed.

Yeah, the phone can't even be used while charging without it overheating. I would love to just be able to stop it from dimming the screen. Quite honestly, is the screen being dimmed even helping with the heat that much? If I could just take that error away and not have to worry about the heat, I'd be fine, honestly.

Someone got any ideas of before / after rooting for the temperature throttling? I don't know why it would change anything but - -

[Q] T-mobile G3 Battery smells burnt at heavy use, CPU and battery Temp

Hi all, I've had the T-mobile LG for couple weeks now and the phone heats pretty bad although I've never got the high temperature warning yet. However, I'm a little bit concerned about the battery temp.
My battery temp has gott up to 42C/108F when gaming ( I was playing Golf Star to be specific) and even up to 45C/113F when I tested the phone with UHD video recording (the CPU temp got over 80C/176F during that video test). On the back of the battery there's little icon showing >40C/104F with a cross. I was wondering if it's dangerous if the battery got over that temperature when the phone is being used?
Moreover, the battery even has some sort of burning smell when its temp over >38C/100F now. Is that something I should concern about? It smells fine when its temp is around 35C/95F or lower.
The battery temp while charging seems fine when it's only around 33C/91F. The CPU usually at 45-50C/113-122F when charging.
Ambient temp has been around 40F-50F when I notice the issues above fyi.
One more thing I'm concerned about is the CPU always gets over 70C/158F or even 80C/176F every time when it starts up.
I was also wondering if I should be concerned with those issues and whether your guys experience similar issues. My phone was running with everything STOCK when the above info is recorded
Thanks in advance for your inputs, guys.

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.

is there something wrong with my Note 4?

Attached below is a picture of my Hardware activity while playing Power Rangers Legacy Wars which admittedly is a graphically intense games but I'm worried that the temperature of the GPU and or CPU is getting too high. I want to make sure my Note 4 isn't getting too hot here is the picture:

I need somebody's help. The coolest my Note 4 seems to get is about 53 degrees C and that's when I turn it on after it's been asleep on my desk. It is not a rogue app or anything like that because I have done both Factory resets and I have install custom roms, so everything has been factory reset multiple times. The water damage sticker indicates no water damage whatsoever. I know phones can get hot when gaming, my Note 4 gets to anywhere between 70 to 85 degrees Celsius and I am just wondering if that's normal I reduced my screen resolution to 720P and disabled two cores of the quad core processor and it does not seem to help one bit. Is this temperature normal or do I need to get rid of the phone?
PS when doing normal browsing it seems to hover around 60 to 67 degrees C
And the battery does not seem to go over 37 degrees Celsius

If you're worried about high temps during games I'd recommend turning the max GPU frequency down. It significantly reduced my temps and I didn't notice a significant difference in gameplay.

Thank you for your response. I have done that and it does not seem to make a difference I'm still getting CPU and GPU temperatures in the high 70s to low 80s

Would you mind posting a screenshot as above with the same overlay? How long are you playing before it gets to this point? Have you adjusted throttling temperatures?
Edit: Saw your other post and wanted to add some troubleshooting. When you open up TWRP and do a file transfer or backup how hot does your phone get? Mine would get pretty hot to the touch, but I don't remember it getting above 80 C.....
The temps you showed in the other thread are definitely not "normal" from my experience with day-to-day use. Did you ever look at the task monitor app I linked to?

Sure I can take another screenshot. How do you want it? I did check out that app and the only thing that I saw was that it seems as though my CPU cores were always running pretty high but I didn't see any applications taking up and unusual amount of processing power. The temperature ranges to about 60 as soon as I open a game for the most part and continues to slowly rise from there. Yes that's about the temperature I get everytime I go into TWRP. I don't even have to be doing anything I'm just open TWRP work and that's about the temperature I get

Sorry, I posted that before I noticed your updated screenshot. I was just curious if limiting the GPU made any difference.
Honestly I'm running out of software suggestions. Do you have some sort of case/screen protector that could be affecting it? How hot us your screen (qualitatively)? I just looked at an old video I made and my phone was 52 C in TWRP, which isn't too far off from yours so it might be fine (as I said my phone screen would get too hot to touch at times during intense games). But if you look at kernel adiutor and see that the CPU rarely drops to the lowest frequency/deep sleep there's probably something wrong (unless your screen is constantly on). You could try a different kernel or governor, or check an app like gsm battery monitor to see if GPS or something us hogging CPU time, but I don't really have any more ideas. (Although I did used to cool off my screen with a wet towel when it got really hot)
Just to confirm: you're running a Verizon note 4 right? (Have to ask)
You've updated the modem to the correct version through Odin?
You're on the proper bootloader?

First of all thank you for your help once again. I don't know how to measure how hot my screen gets I don't have any tools that would allow me to do that I do have a case and screen protector on but it doesn't seem to be any worse than it was before I put them on. Yes I am on the correct bootloader and I do have a Verizon Note 4 running the nseven ROM and I am on the correct modem. I'm willing to do anything at this point. This is the second note 4 I've had with this issue and I just want to be able to use it. I want to be able to play my games and stuff you know. So if there's a literally anything I can do . plus I don't really have money for a replacement

I found this: https://forums.androidcentral.com/s...bout-cpu-temperatures-according-cpu-z-s6.html
Which shows some pretty high temperatures during heavy and normal loads for a G4 and some other forum discussing how their note 4 would reboot due to overheating. Since you're not experiencing that issue I'm not sure you need to worry too much. Your processor should be throttling itself if it's getting to hot to make sure it doesn't get damaged. I'd try to make sure that you limit your gpu to around 300 and then just make sure your CPU isn't overclocked and you will probably be fine. My note 4 would get so hot that I couldn't touch the screen, but it still ran like a champ and never rebooted on me. The only thing that is concerning is that your CPU clock specs aren't sticking, but you'll need to read around for how to fix that since I've never had an issue.

Okay well that makes me feel a whole lot better thank you. According to GSMArena the processor speed of the Note 4 is 2.7 gigahertz and mine is currently running at 2.4 so while it is a little upsetting that I can't bring it down any further, at least I know again according to GSMArena that my processor is not overclocked. Thank you for everything
