[Q] Automatic Brightness not working

Hi,
My automatic brightness setting just leaves the brightness exactly on what it was before. E.g If I manually put slider to max, and turn on automatic brightness it stays on max (even if in a dark room), and if I put it minimum and go outside or shine a torch on it, it doesn't go higher at all.
I'm not sure when this first started happening, it always used to, I'm running ARHD 5.1.11 (a ginger-sense rom), with golauncher ex. I can't think what's causing it. Elixir says that the sensor is working (the numbers adjust as I put light on the sensor).
Any ideas would be much appreciated.
Not a direct fix for your problem but I downloaded OnOff Widget Pack. This has a great brightness control. Running Auto Brightness for most situations seems to be a drain on the battery.

Max brightness in video's with auto-brightness

Hello.
I just received my ZL and noticed the following compared to my previous android smartphones.
I'm currently using auto-brightness ("Adapt to lighting conditions") mostly because the screen uses so much power.
Now, when I watch a video in MXPlayer, and turn the brightness to max (well, it's set to play video's at max brightness), the screen doesn't go to max brightness but instead uses the auto-brightness slider settings (as if you are using auto-brightness with slider maxed out).
When I turn off auto-brightness, the max brightness is way way higher.
On my other phones, MXplayer would disable auto-brightness and use the max brightness supported.
Any one know any way to change this?
Thanks

Max brightness and resolution control

Is there any way to set max brightness and lower screen resolution without going through power saving mode? Everything runs way smoother at FHD and really don't need it at max brightness at any point of time. I can customize them with medium power saving mode on but it also disables always on display and button lights which I want to keep.
Settings/display/screen resolution/pick whatever you want and reboot to get everything sized right. You can then adjust the brightness using the slider however you want.

Redmi Note 5 AI auto brightness doesn't work after 9.0 PEI update

Hey guys, I wanted to ask you guys, what is the problem with my Redmi Note 5 AI/Pro after Android 9 update?
I have a rare problem with my Redmi Note 5 AI/Pro/Globle version. The problem is that, my device does not adjust it's screen brightness even it's set to auto brightness control. And the peculiarly is that it goes down automatically if i adjust it to higher level and auto brightness is active but it does not come up even if I go to eclipse.
Mine works but it's still way too dim and reduces automatically after a while even if I force it brighter manually. I thinks it's related to pie adaptive brightness which can't be turned off in miui currently.
There's a magisk module (miui auto brightness) that helps a bit - it limits how dark the phone gets but the behavior is the same.
I've seen more than a couple bug reports related to that on miui forums, maybe they'll fix it.

Same here, have to do it manually.
Auto brightness works fine (brightness slider moving slowly but brightness adjustment is as expected in auto brightness mode)

Android Pie use a different algorithm to adjust brightness, it now encourage you on manual adjust the brightness yourself and AI will try to learn it instead of the old traditional sensor brightness.

Well I don't know what Google did with adoptive brightness or ambiant display but my Redmi Note 5 is just not working with this new feature and I don't know how to go back on to my older settings. This only forces me to every time go and adjust my display brightness manually. The worst thing is that i have to adjust brightness in the bright day light, like when i come out from a dark place and i just want to check any update I can't see my screen at all until I adjust the brightness to up. And to my surprise, sometimes when I scroll down the brightness bar to adjust it to an upper level I can see the bar is on the highest level but screen brightness has been lower from somewhere else, which I can't understand.
Somebody give me any good reason for Xiaomi's new auto screen brightness control system on Xiaomi Redmi Note 5 AI after PEI update, why should I have it on my mobile when I have to adjust the screen brightness manually every time I want to check my mobile for anything. Either it's on #Xiaomi's part or #Google's but I don't want it on my device.
I can confirm that, with the 10.3.1.0.PEIMIXM rom the auto brightness function not working properly, it's horrible!
