Hello, I'm using a Samsung Galaxy S7 Edge and I've had this annoying problem ever since I got this phone in 2017. The screen brightness keeps changing automatically even though I turned off auto brightness.

Here is a video example. As you can see, the brightness changes by itself when covering the light sensor, even though auto brightness is set to off. It might be hard to see the difference in the video but it's quite noticeable in real life.
Is there a way to fix this?

Does anyone notice the Prime has problem on display? The brightness on my one up and down from time to time. Not very frequent, but noticable. Tried different settings, all 3 power setting, auto brightness, disabled auto...
It is on 4.0.3. Didn't know if it was on HC since I upgraded it right away after got it. The series is c1okaxxxxx.

I have noticed this. However I don't think it happens on user defined brightness (auto turned off). I'll have to check
I noticed that my auto brightness started acting strange after the OTA update on Feb 8. Mostly, it got very dark and I had to turn off auto.
It does the same for me, it changes the brightness even if I set manual brightness. Either it is some kind of 'dynamic' brightness to improve contrast on screen or a bug.
I have written to Asus tech support, no response yet...
Do you think it is the same as flickering issue or related? Does your Prime have other issues?
For my one, the GPS is not working at all. It is also doing reboot after FC sometimes.
Hi!
I have the S6 edge since yesterday and I noticed that auto brightness does not work.
Testing the senosr via a sensor read out tool, it actually detects brightnes levels well (as far as I can tell).
However, if I turn on my phone, it is first super dim at first. When I expose it to a flash light, the screen turns brighter and eventually maxes out. But it does not turn back to normal brightness levels once I remove the light source. Sure I can adjust auto brightness with the slider. But it is then much brighter (with same light conditions in the room) as when I truned on the phone...
Only if I turn off auto brightness, the screen reverts to the setting I have chosen...
If I turn auto brightness on again, it is as bright as with flash light exposure...
What is going on here?
Does anyone have an idea how to fix this?

I have the same problem. Already talked with Samsung and ATT. They want me to change the phone.
Ps. It seems the problem only persists in S6 edge not in S6. But I also found that other android that run lolipop 5.01+ have the same issue too. And right now, I use the app name velis auto brightness to fix this.
I will try to change the phone by this week and update you.
Hope this help.
I have started using an app called Lux. And it has no problem adjusting the brightness. The sensor clearly works fine as it can always displays the brightness detected by the sensor. So it has to be a software problem.
I could imagine that a hard reset could fix the issue. But right now, I do not want to go to the hassle to restore everything
Let me know how the new phone works. :highfive:

The hard reset did not work, I already did it.
I will update you again once I change or test the other phones.
I went to the store, and both S6 and S6 edge in the store all have the same problem, so the exchange it may not solve the problem.
I think this problem may be a software problem or an intention from Samsung/Google.
I will try to use it in couple days. If I cannot bear this, I might return the product.
Hope they will have OTA update soon.
Got this too.
It's really anoying.
I really hope there will come an app like on older Sammy's that we can set and adjust our own brightness levels.
But I'm not expecting a fix from Samsung tho. They have proven again and again they are unable to fix their crappy software. Especialy if it's a minor bug like this.
So anyone wanna buy a rooted hardly used S6 Edge plus?
Auto brightness... What happened? It used to just work. You know, automatically. If you adjusted the slider it would snap out of Auto mode and lock to what ever you set it at. Going back to full auto was a s simple as selecting the checkbox again in the quick settings.
I don't know if it's part of Marshmallow or TouchWiz but now the brightness slider controls the automatic-ness of the brightness. So its more like a auto "range selector" or "sensitivity selector" it seems. Its more of a semi-automatic mode.
If you set it to ~50% the brightness will adjust +/- 10% around that setting. But it doesn't seem to just automatically do 0-100% on its own anymore.
Set it near 100% and it'll practically refuse to dim in low indoor lighting.
It also seems to respond to whether or not you're holding the phone. It'll get brighter no matter what (thankfully), but it will not lower the screen brightness until you put it down on a horizontal surface... Kind of annoying if you're reading and happen to walk in to a dim room and you're being blinded by your phone until you put it down and then pick it back up. I have Smart Stay turned off so that's not it.
I definitely prefer the plain old, dumb, just works, auto-brightness that I could snap on and off if I needed. Now its...complicated. Why "fix" what isn't broken. Was it confusing some people?
I tried Lux Brightness control app but I'm not sure it's really what I'm looking for. It's too much. I just want "set it and forget it" Automatic (0-100%) brightness like it used to be.
It's a feature. The brightness slider will now bias the automatic setting toward higher or lower brightness while still maintaining the automatic adjustment functionality. Turn off the automatic setting check-box to accomplish full manual control.
What ever happened to just plain Automatic? I don't want to have to mess with a slider. It adjusted the brightness fine before. I find that now it's either too bright or too dim for many situations and I'm constantly messing with the slider. Whereas before, auto was just auto.
Same problem here... It is very annoying

Interestingly, with my old s3 and now my current s6, when looking at battery usage, the screen was always about 15% and usually the second item in the list of things that use the most battery power. It was what I always loved about amoled. Now, screen is number one and comes in at ~50% after the marshmallow update. I wonder if it's because it's always so bright now? Or perhaps they've changed how battery usage is measured. Not much I can do about it. Just an a interesting observation.
Hi
I'm just wondering if anyone else on here is facing the same issue? Or if this is working flawlessly for everyone?
When I have the phone on automatic brightness and go outside on a sunny day, the display will occasionally turn on the maximum brightness mode, but only for about 2-10 seconds and then it goes back to the standard maximum brightness that you can manually adjust it to. It also doesn't go back to the super bright mode after no matter how long I have tried to get it back. I even aimed the screen right towards the sun in hopes the screen would get bright again. The super bright mode works maybe once every time I turn the phone on, and then immediately turns back off, after a few seconds, extremely frustrating.
Is anyone else having this problem or know how to fix it? Maybe there is some way to manually activate the outdoor mode?
Also found this reddit thread with the issue:

Thanks
I also want to have this function manual enable but at the moment I think they don't care about this. The screen is too dim compare with other top phone. I have 2 lg g5 and I think that is the reason I am gonna sell both phones.
It may be too dim in Auto but the maximum brightness is bright enough. I don't need to burn my eyes. The maximum brightness is already too much for day-to-day use.
I do wish :
1. that 100% will be the true 100% of this screen - meaning the brightness boost I get in the sun.
2. the in the display setting, I could set the auto brightness to be + X% of the default value. For example, if I set it to +20%, then if the usual auto mode sets the brightness to 50%, it will actually set it to 60%.
Overall this phone is solid, fast, camera is amazing , sound is good ..Sure, a 3500mah could have been nice but I'm happy.
I'm using a stock BLU R1 HD running Android 6.0 and within the last month, give or take, my phones brightness has randomly been spiking or plummeting before evening out into something legible. I also use Twilight(With pro unlock) and I have for years. I have disabled Backlight Control in the app. I have tried to go into my settings and disable Adaptive Brightness, but it will not stay disabled and turns itself back on as soon as I leave Settings. I've recently installed Lux but the problem persists. I've been googling it and all the responses I find are from 2015, give or take, and most apps regarding brightness have also not updated since around that time.
The frustrating part is that most of the time when it changes I'm not even moving and the light around me is not changing. The problem actually occurs more in normal, indoor lighting than it does in darkness or bright sunlight, and I've been careful not to cover the front camera, where I think the light sensor is, just in case I was the problem.
Does anyone know what I can do? How I can either fix Adaptive Brightness to stop randomly changing my brightness for sometimes 10 to 15 seconds before going back to where it should be, or how to disable Adaptive Brightness so it will stop turning itself back on?
I'd prefer not to root my phone, so please don't suggest it unless there really is no other option. I've ruined several phones that way in various ways and have concluded that rooting is just not for me.
