Screen keeps dimming

I had to switch out my s7e and my 2nd unit keeps dimming the screen when in low light. I have brightness at max and auto brightness turned off. Are there any fixes for this? Does anyone know if the Base (sp) rom fixes this?
Test if your device does this: set screen to max brightness and turn auto brightness off. turn your screen off. Turn off the light in your room. Turn screen on and unlock screen. It should be a bit dimmer. Now turn screen off, turn the rooms light back on, and turn the phone back on. It should now be brighter. Does your phone do this?

Bump

Mine does it too and while this issue has been documented on different forums I have yet to see a real season or fix. Found posts about it also happening on the S6. It is irritating as I thought that auto brightness turned off should completely prevent this. You can trigger changes by covering/uncovering the proximity sensors at the front top of the phone with your fingers.

Slow wake-up

Hello friends,
I have noticed that when Adaptative brightness is on, my phone take a few more seconds to wake-up from its screen off, sleeping state.
There is really a noticeable difference than when Adaptative brightness is not enabled. I'm wondering if anyone else had noticed this, and if there any way to fix it.
Regards.

Thanks this was exactly my problem with Android N final release. As soon as I turned off adaptive brightness my screen wakes up right away. Did you ever find a fix?

Samsung S5 901F - Green flickering screen

Hello
My S5 randomly began flickering with a green screen to the point where I was unable to use my screen. It seems to happen a lot especially when I have the "Auto Brightness" feature on and when it's in a low light environment
I didn't drop the phone , and i tried many solutions , wipe data partition , change the ROM ( to official )
but no solution solve it
PS: I can't make a link from youtube explain my problem by video , but you can search on youtube " Samsung S5 Green flickering screen " to know what exactly the problem is !

yes that's happened often and the phone unlock without any problem, but sometimes the green flickering won't let me unlock the phone

This is a common problem with AMOLED displays. At a certain point when auto brightness or you manually turn the brightness down, the low power involved makes the screen flicker. Try turning off auto brightness and adjusting the sloder until it stops flickering, then you can use apps like Pixel Filter and/or the xposed module Screen Filter to further darken the screen to save battery.

This is a hardware failure. The fix is change screen which can cost as much as a new phone. There are several youtube videos showing that applying hot guns can fix the problem

[Problem] Screen flashes bright on touch

Hello everybody,
I have this problem since few months:
Sometimes out of nowhere the screen starts flashing (like turning up brightness to 100%) for a split second when I touch it. After a while it stops. I have no idea where it comes from or how to replicate it. Sometimes restarting the device helps, sometimes not.
Automatic brightness is turned off.
Can anyone think of the origin of this problem or how to solve it?
It is a A2017G and on 7.1.1 with A2017GV1.2.0B05 but was the same with the last update (B04?).
Anything I could think of would be SystemUI Tuner, but I only use it to hide the NFC icon.
Thanks!

Try turning off assertive display under display settings

ZE552KL screen flickering at lowest brightness level

I would take a video of this issue, but I don't have a good enough camera. It's really, really hard to capture unless you have good video recording tech, which I don't have. :crying:
My issue is that, when I set the brightness to its lowest level on my Zenfone 3, the screen starts flickering. This is especially noticeable with white backgrounds. You can tell that the screen is flickering (perhaps refreshing?) rapidly and it makes the phone painful to look at.
Someone actually created a thread about this issue here on XDA a few months ago, with a video showing this issue, but unfortunately, the video doesn't capture the flickering properly. Here: https://forum.xda-developers.com/zenfone-3/help/ze520kl-low-screen-light-level-20-t3603502
How to reproduce:
-Turn auto-brightness off
-Slide brightness bar all the way to the left (AKA to the lowest level)
-Open a white background/grayish background or blank page in Chrome
-Screen starts flickering
It happens across the phone, and intermittently. Sometimes it happens, sometimes it doesn't. In Chrome, in games, whatever. I once thought it could be related to charging the phone, but the screen has flickered on low brightness even when my phone wasn't plugged in, and at 70-80% battery. I might try resetting the phone to see if it's a software defect; I really hope it is.
Turning off hardware overlays in Developer Options does not resolve this issue.
I'm currently on ASUS stock Nougat, unrooted. I can't root right now. I don't have any screen overlays apart from CF.Lumen, which isn't set to come on during the day, when the flickering happens, and I don't use any screen color modes apart from the default settings. I also always have auto-brightness turned off.
Just wondering if anyone else is having this issue. I might try recording it one day.
Thanks.

Update 1: Removed my 64GB SD Card from the phone to see if that made a difference. It didn't. So the flickering isn't related to power management, AFAIK.
Next step is to wipe the phone completely, including its cache partition from stock recovery, and set the phone up as new again. It might be a hardware issue, but my fingers are crossed.

I've had this issue since I got the phone, ZE552KL. Turning off auto brightness fixes it for me, so I have a feeling it has more to do with ASUS' auto brightness algorithms than anything else.

I always have auto-brightness turned off. I think it might have to do with the ambient light sensor. I've tested it using SMMI and it works just fine. But I wish there was a way to disable it, since I don't need it. I'm kind of disappointed in this phone.
I'm going to try a full reset, and perhaps a custom ROM to see if it's a hardware or software issue.
