Question Disable brightness limit - Samsung Galaxy S21 FE

Hi,
My S21 FE has a brightness limit that kicks in when the phone gets warm. However, this temperature threshold is too aggressive, the phone isn't that hot, it's just summer... other phones don't do this at this temperature only at much higher...
The screen gets too dark to read. This limit must be aroubd 60%. So I'm looking for a way to disable this limit but without rooting or otherwise voiding my warranty. After all, Android is about customization, I don't see why Samsung would force this on me, virtually making the phone useless in the summer.
I found this method but it seems scary, it uses KNOX and MDM and whatnot. If I only make the change described in the guide and then remove this app altogether, can I undo the change with a factory reset? Will Samsung figure out that I "modded" the device in case I don't fry it, just change this setting?

I guarantee that the device will not overheat. Samsung is too paranoid. The xiaomi 12x just next to this phone is doing fine...

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.

screen brightness issue/overheating

i've had my phone since launch and ever since my screen brightness gets automatically reduced due to overheating.
At first, the screen will dim itself ever so slightly. After a few seconds later, it returns to normal brightness and it repeats itself.
Eventually, i notice upper half of my phone as well as the screen itselft getting really hot and the brightness dims permanently.
I usually keep my brightness setting at the highest level but when i go into the menu to increase the brightness setting back to highest, it tells me the brightness is reduced due to overheating. only way to increase the brightness back to highest is to turn off the screen and let it cool down for a few min.
whenever this happens im usually browsing the internet for no longer than 10 min before this kicks in. i seriously dont think im using too much cpu by browsing forums for this super phone to be overheating.
i've read other post regarding auto brightness feature causing issues but i have not enable this feature on my phone. and its kinda hard to believe that i have to lower my brightness to prevent it from overheating.
anyone having this issue? man i'd hate to return this phone and start from scratch. tia
I would love to hear more about this...My experience matches yours perfectly. Does everyone's phone do this? If enough people say no I'm going to get a new one...it is absurd. I got those phone almost primarily for it's beautiful screen which I can't see at full brightness for more than a minute or two!?? fnck that.
Is it possible for us to get a brand new replacement unit even if your 15 day return period is over? Assuming that other users are not experiencing the same problem.
Mine does this as well, I think it's some kind of fail safe if your phone is running hot cranking up the brightness is just going to add more heat so they limit it while it's running hot. Once it cools down then it will allow it again
I have this same issue, I have to recharge above 30 percent to get the point where I can max the brightness up again
Hmmmm... guess im not the only one with this issue and hoping that it is addressed in the future update. However, it seems odd that no one brought this up? Could it be that there are only a few of us that are affected? If so, im beginning to think that this is a hardware defect?
Ive had the phone since day one. I am not having this problem. The only time it ever gets noticeably warm is when using the phone for extended periods while charging. And this is not hot like some people are reporting. I would try exchanging the phone.
Mine did this the other day, I normally have auto brightness on but I was showing a photo so i went to turn it off and crank the brightness up but it didn't let me. I pulled the battery for 10 seconds and it let me do it.
I think alot people are not experiencing this issue because they either keep the auto brightness feature turned on or keep the brightness setting at a low level. I dont wanna exchange my phone if im gonna have the same issue. What can i do?

You may be on to something.... I rarely ever have my screen at 100%, mostly because its just too bright for me.
Although, I did watch 2 hours of video (1 hour from the SD card, one streaming from Netflix) at full brightness, and never had a heat issue. A little warm, maybe, but certainly not hot.

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

Nexus 5X Heat (normal or problem?)

Hello everybody, before, I know there are several posts on the xda about the phone get so warm, but I think I have a different question. At this point in my country are about 35/36º Celsius, which obviously makes the phone warm up a bit, but i without open any application the temperature reaches 42/43 Celsius, but it will be normal or is a situation to worry ? I see quite a few posts from people saying that the mobile phone reaches 60º, the maximum I could get on my was to 48 and had several applications open and was playing a game. Like all others, the mobile phone is quite hot in the sensor zone and sometimes is hard to use, I even installed an app to close all applications to save battery and cool the phone. Therefore, it is normal but all phones warm up a little when they are being used aggressively, but it's normal after unlocking and without any open application temperatures reach 42/43 celsius? Should i send for warranty or not because this is normal?
Thank you in advance any help :good:

This phone is going to heat up considerably in that temperature due to the 808 CPU. If you spend a lot of time outside or in a warmer environment, there may not be anything you can do. Depending on the case, that may also keep the phone running warm as well. Try an RMA and see what happens though.

If the ambient temperature is high then the battery temperature will start high as well. I'm assuming you're monitoring the battery temperature since that is what most apps will report.

Unless it's Greenify, get rid of it. Apps like that can cause more harm than good, and your phone might actually be running hotter due to apps closing/launching more than necessary.

Ok, i will take your help, i unistall the app i use to see the temperature and now i use greenify..
Sorry if this is a stupid question, i switch from a micro sim(old phone) to a nano sim ( nexus 5x) but yesterday the SIM stop worked, i have a new one now and looks like my phone dont get so hot, is this possible or is this my imagination?

Do you have better signal with the new SIM? If the phone has to constantly search for signal, that uses a lot of power and heats up the phone.

I believe yes, i have the 4G as the preferable, but after this new sim i don´t have 4G often, now i do... is a fact :good:

Question Phone running hot and shutting down

Anyone ever notice their phone getting hot and shutting down features or even turning off? I know this might be kinda extreme... My 6 pro has been shutting down all sorts of things just to cool the phone and eventually shutting off. This has been happening while I'm in a sauna after working out with the lowest brightness on even. But my Note 10 plus never even mentioned anything to me ever even with full brightness. Thanks for the help
It happened to me once with a Galaxy S7 but it was in a heatwave that said I read on forums that several users complained about an overheating problem on the pixel 6.
As the chip is made in partnership with Samsung and it is well known that exynos chips overheat other than waiting for software upgrades or sending it back there is nothing that can be done.

Interesting that your Note 10 Plus works in a sauna-environment. I would definitely call that an extreme situation where no phones needs to properly work, after all we are talking about an ambient temperature of ~ 65°C to 90°C, that's much hotter than even a desert. Most commercial products only operate up until 70° Celsius, Industrial usually up to 85°, Military ones even higher.
Personally I would never/have never taken my phone inside a sauna out of fear it might get damaged, after all it's a thousand dollar product. Treating it with care and caution is usually a wise choice, if longevity is of any concern.
Most smartphone (and desktop) processors can only take about ~100 Degrees Celsius (internal, chip temperature), before they throttle down into the abyss and try to cool down (to prevent permanent damage). But if they are in a sauna... there is no cooling down, lol. Afterall they lack a dedicated fan. As an example: It's a situation comparable with your ambient room temperature in the summer - if you have 30° Celsius in your room, but outside it's 40°, your room of course will not cool down, but heat up even more. ESPECIALLY not if you have several heaters on (= processor, display, et cetera).
That's why it's quite the achievement of your Note 10 to properly function in that kind of situation, that seems like a well-balanced phone in terms of heat/cooling. Props to Samsung in that case.
According to several reports in this forum, Tensor can get quite toasty, even in a normal environment. It shutting down in a sauna does not surprise me. There's probably nothing that you can do here, expect switch the phone or hope for a Google firmware update that lowers the coreclock.
I haven't had any overheating. I think the very first day when I was setting up the phone and restoring from my cloud backup it got a little warm, but mine hasn't overheated at all or shut down anything. I am probably not pushing the envelope of what any phone could handle, however.
Haven't witnessed any overheating on my unit.
Never had this happen on any of my recent phones including my Note 10 plus and my buddy has a new 20 Samsung as well.. No problems for them or anyone else with their iphones and a few others while they are in sauna as well.. even my samsung ear buds murder this thing lol
NOTE TO ALL POTENTIAL 6 OR 6P BUYERS: this is not a common phenomenon. Just want to put that out there.
I use GSAM bettery monitor (with the ADB mods) and it works great to watch the temp. Once or maybe twice it got warm (107F) when I was backing up the entire unit to my NAS (or vice versa). Ever since it gets warmer when I use it more, and then cooler when I don't.

I think you answered your own question buddy... The temperature in the sauna ranges typically between 60oC to 95oC. Your Pixel phone is designed to operate up to 45oC at extreme situations.
I'm afraid the problem lies with the owner in your case, not the device itself.
A Sauna?! A SAUNA?? Did I read that right? I .... I .... I just don't understand. And when my sister "washes" her Galaxy S20 under the tap, the first thing she says: "Samsung says it's OK! The phone is Waterproof and Heat Proof and Mud Proof!" ... ok the last two things are false but every galaxy owner I've come across thinks their phone can be used in a shower, hmmm....
Again... I knew I would catch some crap for posting this.. but I'm trying to figure out why most and yes I said most phones do not have a problem including my old note 10+ and also my other friends phones and random people as well..
My Note would be full brightness and wouldn't even really feel hot. Warm yes and it would continue to work just perfect.. I even tried to put my 6 pro in battery saver mode which shuts down cores and it still could not last 5 mins at the lowest brightness.. My Note in performance mode and full brightness would last the full 25+ minutes I would be in there.
Looking for advice or answers. I've stated comparisons with the same scenarios with two completely different phones of my own along with others. One works great and another does not..
