Hi ppls!
I can't call it a problem but it's sometimes annoying.
The 'problem' is that when I leave the phone the brightness sometimes jumps to 100%!
Is this because of the auto adjust brightness? The light condition is not changing alwaya when I leave the phone and it jumps to 100.
Is it possible to do something about it? Is it a hardware failure or are anyone here also facing the same 'problem' as I?
Thanks in advance.

Screen brightness gets stuck on 100% and I say about 6 out of 10 times I had to adjust the brightness down on the phone when ever I closed the camera anyone else?

Yep, somewhat well known issue.
Known issue updates seemed to help it not get stuck at full
Is it just me, or is there some problems with the auto brightness feature on this phone? From time to time the screen suddenly get a lot darker, even without the lightning in the room changing at all.
My phone is Telenor(Norway) branded, with the firmware: PDA:XWKF3| PHONE:XXKE7| CSC:TENKF1
Did some searching on the issue, and found some articles saying this should have been fixed in a firmware update, checked with Kies and i got the latest firmware, so either this wasn't really fixed, or is there something weird with my phone? Or something else maybe?

Yep your hand is over the sensor. I run with it disabled since it doesn't work well at all, and it's so easy to manually adjust brightness by swiping the notification bar.
Gotten a clearer view on what the problem is now, the auto brightness it self seems to work, but it's a bit slow and very direct. If am in a light environment and it gets dark, it doesn't start lowering brightness right away, but it takes 3-5 seconds and boom brightness goes very low. That's why i thought it was something wrong with it.
In my opinion they need to smooth the auto brightness out, and let it react faster, would make it a lot better.
Hi, I was wondering why our Galaxy's screen reduces brightness before going asleep. If you notice, pressing the power button the display doesn't turn off instantly, but it turns very dull for a brief moment and then it turns off.
Can you tell me why? It is quite annoying. Other phones turn off instantly, like many HTC's I've seen. Does this concern the SA+ screen? Do you know a fix?
Have a nice evening (21.30 here in Italy)
Only just noticed this now.
Why does it bother you?

It does not, I was just wondering.. I'd like to know if it's a software glitch or if it's something about the hardware.
I don't think it's a glitch as I've seen many gs2 do it.

Yes, I meant a firmware/kernel glitch but no one of the roms/kernels I've tried solved this out :\
I just bought an s4 today with Verizon. I'm laying here in bed and I noticed something strange which I never saw on my note 2 or my s3. I was reading a Web page with my brightness turned all the way up and it seemed like every 20 secs r so it would get a little dimmer then it would get bright again. I have adjust screen tone turned off. Then I went to settings, display, brightness and I see this message that says something like max brightness had been turned down to avoid overheating. Is this why my screen seemed to be dimming then getting bright again? Yes, the phone was quite warm during all of this. It also only happens when the brightness is turned all the way up.

Its because of the heat if your phone it turned the brightness down. Because it could be a big source if heat. Interesting enough that has never happened to me.
This happens at any brightness I think and not related to heat- some of the main browsers have a slight auto adjust brightness even if the phone setting is turned off. I read it a few times so I assume it is that. I see this as well using Chrome.
In a dark room, have brightness to middle or something, and be on a light/white web page in Chrome.Pull the notification bar down and without really noticing, the screen will get slightly brighter due to the darker color. But drag the bar back up and instantly you can barely see the screen go back slightly darker again for the browser.
It was happening using any app not just a browser. I literally sat here and didn't touch the screen at all and I could see it go from bright to dimmer then to bright.. Back and forth..

And I've seriously never seen that message about brightness being turned down on my s3 or note 2. I don't even know why my s4 is so warm right now..

guys, it's a heat issue.
when the phone reaches a certain temp (i believe it's around 35 degrees C), it automatically dims down your display, no matter waht the brightness. you can be on 0 brightness, and it will dim anything that's a bright page, like a bright white.
test it by doing this: be in the browser when you notice it dim, and tap on the URL bar to bring up the keyboard...notice how bringing up the keyboard restores the brightness to what it was before that? that's because now the screen isn't engulfed in a super bright white screen..now it's divided between half bright white, and half darker from the keyboard, so it thinks "okay, the screen isn't fully white now, so we can go back to original brightness."
i suppose another way of showing why this is, which is much easier and idk why i didn't write this first lol but go into the brightness control in the display menu when it does it, and notice how it says "screen birghtness will be lowered to reduce risk of overheating" or soemthing. it only says that when you hit a certain temp.
the phone gets really hot, period. that's just how the S4 is unfortunately. so you may notice this happening often; i do lol
My phone does this too. I was wondering why it was doing this too. I guess the heat issue makes sense.

Yeah dude that's exactly what the message said and I've never seen that before in my other phones. Don't understand why it got so hot? I wasn't even doing much... So the s4 naturally just gets warmer? My note 2 never got this warm, ever. I just want to make sure mine isn't messed up...

I also turned the phone off for like 10mins and it feels much cooler now but that message is still there.

My s4 does not really ever get hot and I charge while tethering all the time (same process would heat my s3 up)
Have you disabled the adapt display and adaptive backlight settings.
This was happening when I was charging it actually. It felt pretty damn hot. I turned off auto adjust but Idk what the other one is that you said.

Is there anyway I can check the tempature of the phone?

I'd really like to know what I'm still getting that message.. Phone barely feels warm..

Here's what mine says. I just downloaded it and went to tempature.

Seems like it's working perfect now... Hasn't got warm at all. Maybe it just did that one time bcuz it was the first couple hours it's ever been used and the first time it's ever been charged?

Also check for the "Screen mode". It is under Settings -> My device Tab -> Display -> Screen mode
I usually leave it at Professional photo for less saturated but more accurate color rendering. If you check "Adapt display" or "Dynamic" it will try to adjust contrast based on scene displayed which may look like brightening and dimming of display, if you had "Auto adjust screen tone" unchecked.
What does the auto button do?

I did notice that my s4 was warmer when i first got it than now... like i was almost hitting 40 often and now i hardly ever hit 35. don't know if it's because I ran a custom rom or not, or the phone was just settling. but yeah my first days with it I was worried

why? very hot or cold
Never noticed this on any other phone before but when I'm on a call, the screen sometimes fails to turn off and I end up activating the notification panel with my fat face and accidentally toggling different settings.
Phone bought from HK and running. 475 without any modifications. Any help greatly appreciated.

I have the same problem. But couldn't find any solutions yet.

i have the same problem too but mine is a little bit different. my proximity sensor is always on. once i answer a call my screen automatically turns off and i have too wait for the caller to hang up before my screen turns on back
Ok I figured out what was happening in my situation. The phone is so big I didn't know where to hold it next to my ear. After a bit of experimenting, I've now found the optimal position.
A bit silly but I'd thought I'd share my stupidity in case someone out there is like me.

This is normally caused by a screen protector covering the proximity sensor try to remove the protector and try again.
