Avoid automatic screen dimming - Android Apps and Games

I use an old Android for offline navigation, works fine. #
However, the screen automatically dims which I would like to avoid. I don't mean the time I can set until the screen turns off. That's no problem at all.

Any ideas?

[Q] Camera forces 100% screen brightness

Does anyone know how to prevent the Camera app from forcing 100% screen brightness? It really is blinding for me especially at night.
Thanks
I can't help if you are on stock software, but I figured I would throw down a tip for CM10, since thats what I run. There is an option to allow screen dimming. I believe by default, once a screen brightness increases on android the only way to lower it is by cycling the screen. The option in CM10 allows the OS to dim the screen w/o turning the screen off.

[Q] Screen dims during call

Not sure if this is an OPO issue or an Android one in general. Don't remember it happening to previous phones...
When I make a call, about 90% of the time, it'll dim the screen. Now, I'm not talking about it using the proximity sensor to turn the screen off. That is a good thing, and I approve. But when I'm finished with the call, most of the time, it's dropped the screen's brightness down to the minimum level. And there it will stay until I manually turn the brightness back up.
Is there any way to prevent the phone from doing this?

screen lights up randomly

whenever the phone is just resting on the table, it will randomly just up the lockscreen for a few seconds, then turn back off.
I do not use any auto brightness. anybody else experience this? It usually happens a few minutes after it's been used.
maybe notifications waking screen to remind you. maybe background app forcing screen wake. have you only noticed this after downloading an app . maybe try deleting recent apps and seing if it persists
i have not had this same issue but with same thing ......with auto brightness off..have you noticed while using it the screen dims. gets lighter? etc you can be on internet page and your screen goes much brighter? also sometimes goes dimmer?
i beleif it to be battery optimisation . or that turning off auto brightness doesnt really turn it off. or there is bug in software that does this.

It is quite possible that ambient display is the culprit. Look in display settings and see if it is enabled.
Hello, we understand your concerns about the display and its brightness. Here are some tips to correct your auto-brightness issue.
- Your phone will automatically adjust the screen brightness according to the ambient brightness. Clear the Automatic brightness check box to manually adjust the brightness.
- For sleep mode, the screen will lock automatically after a period of inactivity to reduce power consumption. Select Sleep to adjust the screen-off time or disable the automatic screen lock feature.
If the problem persists, try backing up your device and performing a "master reset". This should help correct any buggy issues you are having with your display. (NS)
You don't receive notification and it lights up randomly, right?!
Disable voice wake-up from Settings. The same thing happened on my P8.
So voice wake-up os begins this, I've never enabled it, I didn't thought about it

Still the problem exists. I mentioned already we have automatic brightness box unchecked and still the brightness changes.
If you're on MM try to rollback to LP

Try changing Power Plan to Performance if it is set on Smart.

A factory reset should solve the problem, if other solutions don't work
try enabling the power saving mode

P40 Pro Whatsapp notifications too fast & weird screen brightness

1. When using Whatsapp Web, every time I get a message my phone screen turns on. This happens even if I'm talking to the person in question. Uses battery for nothing. Is there a way to get this to either delay a few seconds so it would notice the message has been seen and wouldn't activate screen OR straight up notice Web is in use and not notificate?
2. There's a slight change in brightness when going from bright to dark pages. No auto brightness or anything is on. Any idea how to turn this off?

Question Always on display not working properly

So, since I updates to android 13 one ui 5.0 my always on display is not working as it should. I use the "tap to show" option, and it works fine the first time i touch my screen when it's off. But that's it. If i don't wake up the screen and touch it again after the screen goes black to see the AOD, it won't show.
I find it very useful to use at night, while sleeping, to see the time and not get blinded by the bright display.
I cleared the phone's cache after the update. Still not working as intended...
Do you use energy saving during day? I set a routine to activate it under 20%, so it deactivate aod, but when I charge it and goes over 20%, I have to enable aod again.
I'm having some issues too. I was using "tap to show", but recently it always come back to "always show" at the moment I lock my phone
