[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!!

Xiaomi Mi A2 Lite - Notification LED issues

Hi,
I have a new bought Xiaomi Mi A2 Lite and my notification LED light sometimes does not blink when there are notifications (e.g. WhatsApp messages).
That happens independent of how long the phone has been put away and independent of internet connection etc., the LED light only turns on in around 80% of all cases.
In the other 20% of cases, the light is not flashing, and when I unlock the phone I have a normal notification icon on the top of the screen.
I already checed all settings for notifications, everything seems to be fine.
maybe someone can help me?

Hi, for me deactivating Ambient display did the trick (Settings --> Display --> Advanced --> Ambient display (set it to Off).
Hope that helps.

hi
thanks for the tip, but it still sometimes doesnt light up.
Also, I noticed that sometimes it happens that the light goes on (as it should) when I receive a message, but after some time (15min+) the notification light disappears...
Could be a hardware issue as it works just fine for me.
so I will order another Xiamo Mi A2 Lite and look if the problem also occurs there.. :/
I had encountered this as well at times I thought it was just software issue.

Adaptive brightness too bright after reset

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!

Brightness issue (out door ) with Android pie

Hello. I noticed a problem with the screen brightness. When brightness is on at 100% ( auto brightness is off) and I'm out of the house. For a few moments the brightness goes down( a little down )and goes back to the previous state. My friend and I both have this problem and after the Android pie update, it happened.
We both have redmi note 5 ai global.
There is any way to fix this ?
Thanks
