Screen stays dim after waking from screen timeout
Auto brightnes is off, brightness is at 100%, color is set to standard,
after screen timeout screen dims and when touching it to keep phone awake it does not go to 100% brigtness even though the brightness bar is still at 100%, and then i have to slide the brightness bar to lower it and back to full.
It is very annoying having too do that every time i tocuh the screen trying to keep phone awake.
One solution would be to set screen timeout longer, but then i would have to remember to lock the phone every time...
Another would be to keep it at auto brigthness which is fine in direct sunlight but sucks as soon as the sensor is in the shade
It is latest stock firmware on rooted/unlocked phone
Did you replace your display?
Display brightness works correctly only on android 9miui10.3.5. So fastboot flash it, then check display brightness, then upgrade to whichever rom you want and check if it still works well(some weird hardware sensor issues in miui software updates)
MIUI 12 Fingerprint Unlock defective
After upgrading to MIUI 12 Global OTA yesterday, fingerprint unlock stopped working. When I select fingerprint unlock in settings to switch it on and enter my PIN, phone goes dark and restarts (MIUI splash screen). Any suggestions? Phone is stock...

Hi, got an HTC one recently but i'm having problems with autobrightness seems like the low brightness setting for for phone turns screen completely off. I went to brightness setting manually and drag the slider to the lowest point but the screen will completely turn off just before it reaches the last point so i downloaded lux from the store and checked it the screen while turn off below 15 lux. So my question is, is this a hardware defect or can i install firmware or anyother software to calibrate the light sensor? thanks guys.
This has always been confusing and I am looking for clarification on the Lock Screen/ Screen dimming, etc.
So I went into the display settings and set it not to turn off for 1 minute. Then I checked the power saving settings just to be sure the screen would not go dim or lock after 5 seconds. That did not work. Then I checked the security settings to see if something was over ridding every other time out setting and I am lost. Either these settings have never really worked since the original note and android/ google is lazy or I am not doing something right.
Dose anyone have a step by step walk through of all the settings that would affect when the screen dimms and when it locks? (Sometimes I am running music through blue tooth and I don't want to the screen to dim for specific applications also. There has to be a setting somewhere because Google Maps does not allow the screen to dim or lock when in nav mode.

I really wish someone would have answered your question. Mainly since I have the same freaking problem.
When the phone app is running, I am constantly getting dimmed, seconds only to do something.
Tonight I was using an app that monitors BBQ temperatures. Always dims to fast. Set the screen timeout for 10 minutes. Still dimmed after 30 seconds or so.
How does this work? I'm not sure the screen timeout setting does anything.
The screen diming feature is part of the auto brightness function and works by using the ambiant light sensor to adjust the brightness of the display. According to the amount of light detected in front of the display.
Screen locking happens when you haven't used your device for a specific amount of time.

It dims before it locks. That's what I was referring to. I think the OP was as well.
I set the display for 10 minute timeout. It dims and locks the screen in less than a minute. I can't figure out how to stop it.
Is that a clearer question?
Well my screen dims for some seconds before going out, but, always as per the time I set , for instance, if I set to go out after 5 mins of inactivity, it dims after 4 mins 55 seconds, then goes out, I dont use autobrightness, and I use entertainment mode
It was secure lock time setting.
It was disregarding the screen timeout.
Anyone noticed theirs? Mine auto brightness is already activated, when I unlocked the screen it gets bright even when the environment is dark. But my auto brightness mode is working.

Yes it's annoying as all hell. Takes about a minute to adjust but it's blinding at night.
That happens cause I use iris. So in dark rooms, I just use the fingerprint.
If you don't mind the inconvenience caused by having to swipe first before using iris unlock, disable the "Iris unlock immediately when screen turns on" option in Iris Scanner.
The screen has to be brighter than normal initally in order to provide enough light for iris scanning (without the circles for guidance).
The screen is no longer brighter when using iris unlock later because it now requires you to position your eyes within the circles.
Personally, I'm perfectly fine with the brighter screen initially.
At home you can get around it by setting it as a trusted location and then go into display/navigation bar and switch "unlock with home button" to on. That way you can just press the home location and your phone will bypass security/lock screen and go directly to the home screen. That is you can if you're not hiding an affair or other skulduggery from your partner in which case you might want to skip this method. lol
Anyhow you will retain your set security method outside of the trusted location, in my experience I'll usually be trusted around the house and yard but much past it I wont be. This also makes it nice for when you're home with the phone next to you and you want to interact with it without picking it up, you press home and you're in.
Unlocking screen brightness on Android.
This is only an Android Oreo + ( Android 8.0+). I only have this issue with my newer phone which is Android Oreo. It happenes with whatever method I use to unlock my phone. It's an auto brightness setting but it's doesn't seem to be listed as any sort of brightness setting. It's not even in the developer settings. If anyone knows how to disable the unlocking brightness feature, that would be helpful.
This happens for me when I face recognition on so the camera can see my face in the dark. You can change this in Settings > Lock Screen and Security > Face Recognition > Brighten Screen. Turning Brighten Screen off should keep the screen dim in the dark but you'll probably have to unlock with your fingerprint or something.

Really annoying this brightness. Even try every thing to keep this brightness on manually set point but at time of unlock, it increase in the middle of the night. Please any one help. Is it a problem of software or hardware.
I haven't notice this at all...
The only problem with this glorious device
I'm on Note 10+ and this is the only issue with this device. In the last three months I've used Pixel 3 and Apple Max and they've both figured this out. The blinding light is terrible. Middle of the night, or first when you wake up.
SOLUTION - If you have fave face recognition:
- Go into settings, select Biometrics and security.
- Select Face recognition.
- Tap on the switch on the right-hand side to turn on/off.
We've used EasyProfiles Pro (profile manager) to activate various settings since HTC Desire days. One thing that the P20 Pro does when unlocking the phone is to reset the brightness to mid-way, over-riding the profile setting. Autobrightness is off.
During daylight hours this is not so noticeable but at night when the phone is unlocked it switches to mid-brightness despite the profile settings for minimum brightness. A tap of the profile widget restores it to dim, but each time we grab the phone it's very bright for night use.
I've looked through all the phone display settings and can't see any reason why the phone should revert to mid-brightness after unlocking when Autobrightness and Eye Comfort are off.
Developer of EasyProfiles has abandoned the app years ago so no actions possible on that front.
Can anyone confirm this behaviour ... turn off Autobrightness, set brightness to low, lock the screen, unlock, check brightness level?
CLT-L29, 8.1.0.130(C363)
Update ... been liaising with Huawei support, they suggested B150 would fix this. Update B152 was installed but did not help.
Further testing suggests the problem is the lockscreen always uses Automatic Brightness irrespective of the user settings. To test this I set the phone to a daytime profile, locked the phone, then went into a dark room. When I woke the phone the screen began to dim and when I unlocked the phone the brightness was very low.
Similarly, I chose the night profile and went into a lit room, the lockscreen brightened and unlocking forced the brightness higher.
Sounds like they're going to escalate this, assuming they can replicate the issue.
Whenever i use my phone, its screen brightness dims (Adaptive brightness is OFF) and when i pressure the top right part of the screen the screen gets normal for a while. I've tried to get it fixed from service center 2 times but the problem comes back after few weeks. I've also found out that if i press the top-left part of the screen, it dims the screen brightness. Can someone tell me what the problem is.. Is it some loose wiring or is it damaged display?
