Screen randomly dims - Samsung Galaxy A70 Questions & Answers

Does anyone know why my screen sometimes becomes less bright? I've turned off auto brightness and put it on max brightness and I can see my screen sometimes becoming very bright and then after a while it becomes darker again. Is there some hidden option I've missed?

[Q] Auto brightness error... Auto brightness NOT on

I've had a problem with the t989D since I got it. Here's what I want:
**Auto brightness turned OFF and the brightness remain at minimum setting.**
However, with all the roms I've tried (Stock, Juggernaut 4.1- 5.0, Tuesday) I always have the auto brightness OFF and the screen always brightens up to about 75% whenever I turn the screen back on.
Note: the settings still show as if the brightness is set to 0%, but the actual brightness coming from the screen is the same as if I turn the bar up to 75%. When I start to move the adjustment bar a slight amount for the brightness, the actual screen light drops right away. It only stays on 0% as long as I'm using it, but then is really bright again when I lock, then unlock the screen.
Is anyone else noticing this? Beyond that, is it possible to prevent the screen from adjusting it's brightness while the auto brightness nis off?
Thanks for any assistance!!

Dim LED notification light?

My notification light is demonstrating strange behavior. When the screen is on, the light is fine. After the screen has been off for a few minutes, the notification light dims out to about half its normal brightness. If I turn the screen on, the brightness is restored.
I've looked through the settings and don't see anything to control this. Is anyone else having this problem? It's pretty minor, but it makes it harder to notice in day/light.

dim screen on wake up

most of the time when the phone wakes up and the screen stays dim and grey, as if there is a semitransparent picture in front of the screen. I can see the clock and I can unlock it, but everything is dimmed.
If I turn of the screen one or two times, it usually wakes op again without this grey dim sheet and I can use the phone in full brightness.
I turned off auto brightness, but this did not solve the problem. The brightness slider also turns upp the brightness, but it is still about half as dim as it should be.
can anyone help me in finding out why this is happening?

On Full Brightness…. Auto sensor kicks in by default !!?

If I keep the brightness to the Maximum, I notice that in bright sunlight/extremely bright indoors, the screen gets Automatically even brighter and dims when the phone notices the environment is not that bright !!!!
You can experiment by shinning a flash on the top right side of the phone with slider on max brightness.
Isnt it stupid – When the user have disabled auto brightness or any power saving modes the phone keeps getting bright and dark
I cant believe Samsung has let it pass this to the production models…
bump - anybody ?

Hi
It happens also to me, looks like a screen extra-adaptation, not correlated with auto brightness. I noticed it gets triggered by Telegram, surely also by something else.
In previous OTAs sometimes the screen remained ugly and bright, since sometimes does not happen more.
No idea if there's a setting for it.
