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.

Screen dimming - requires single tap to "wake" - looking for a way to disable
So I am running a stock Sprint HTC One (Android 4.4.2, software version 5.03.651.3) and for months now (for some reason, I thought I first noticed this behavior right after 4.3 got pushed out), there is a single behavior that has perplexed me, and despite trying various configuration changes, I cannot seem to get it to resolve.
I currently have all power-saving features disabled, screen timeout set to 1 minute, automatic brightness enabled (slider, which shouldn't make any difference, is set to the middle), daydream is disabled, and developer options are on with no screen timeout while charging enabled.
What seems to happen is that after about 1 minute (also the duration set for screen timeout, which initially made me wonder), the screen (while plugged in and charging) will dim slightly, maybe about 50% of the standard brightness when the phone is actively being used, and I have to tap the screen (not the double-tap I have been reading about, which supposedly isn't even implemented yet) just once to dismiss the dimming in order to register touch input.
At first, I checked Daydream a bunch of times, enabled it, disabled it, changed settings, and it seemed to have nothing to do with it, because when I did enable Daydream, I got the real screensaver or colored screensaver that I had chosen in the options.
I then disabled auto-brightness, set the manual brightness level to minimum, maximum, and a dozen levels in between, and I still got the dimming that required a single tap to restore use of the screen and brought the brightness back up to its normal level.
I made a bunch of power saving changes, enabled, disabled, to no avail.
Three factory resets later, (tested with no installed apps) I still have the same behavior. It seems like there is a setting that is enabling some sort of screen saver (that only dims the screen to about 50% of the set brightness level, but disables interaction from the user until the screen is tapped a single time) that is dismissed with that single tap.
I've gotten used to it, but it's really infuriating, especially in the car when I have it mounted on the dash for things like GPS, streaming audio (I just want to be able to see what song is playing if it's a new album), and other things that require a glance over to the phone. Sadly, in the car is probably the worst time for the dimming, since the ambient light outside makes the screen appear off when this "feature" kicks in.
I've spent a great deal of time searching/reading threads not only here, but on other mobile forums as well, and I cannot even find a reference to this issue that behaves the same way mine does.
This is my Hail Mary in the hopes that I really have missed something simple.
Thanks in advance for any ideas!
Just picked up an ME572c and I'm very impressed for the price. However I have noticed the screen brightness levels keep fluctuating as if the light sensor is constantly detecting different light levels.
Has anyone else experienced this?

Hi,
i notice this too, but that can be related to the power saving mode. Plz turn it off and check the settings in detail. Maybe that helps.
Further inside the developer options there is another option to configure the auto brightness.
You can change the behaviour from dynamic to immediately or slow mode and active an onscreen lux, gain and brightness value display.
Btw i am not satisfied with the auto control, as for my taste the brightness is still too low in a less lighted room. Sensor is reporting 0 lux already with a brightness of 14 which would be ok for a really dark room & night but not at daytime.
What is your experience?
I tried playing with power saving mode and the auto brightness controls in developer options. While I could reduce the fluctuations, I could eliminate them completely. Unfortunately I found it too distracting and returned the device earlier today. It's a shame as everything else was quite impressive for the money.
I also found the fluctuations annoying, my solution was to turn the auto-brightness off. Honestly I dislike auto-brightness on any device, it was also one of the first things I turned off on my laptop.
I am using Lux app now and raised minimum brightness at 0 lux. Thats ok for me now.

Just bumping this to confirm this works and so that others can see. I used Developer options as well (before I found this post) and noticed the instant setting works best.
One more setting to also double check... Make sure that in developer options under auto brightness that you disable allow change gain...
Even with everything disabled it appears as if something still is changing the display. I particularly see it with something like a reddit browser when I'm viewing pictures. You click the pic, it loads and displays and then 1-2 seconds later the display adjusts based upon what is being displayed. Depending upon the picture it can be pretty annoying. I may have to root and start poking around to find out what is causing this.
with the lollipop update this issue is fixed for me.
Is lollipop really solve the problem?

Hello!
Im on lollipop, but the problem you had, still occur at me.
Did you noticed this problem, since you on lollipop?
I have the same problem. When i read, or browsing, the brightness changes in 2-3 steps.
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.
Hello, does some one knows why the AOD sometimes is brighter sometimes dimmer, regardless of ambient light, it is driving me nuts as I do not find some setting for controlling this…
Btw, I am still on 7.1.1, 950 F stock

I Think it's related to the light sensor on top of the device. When you get your phone off your pocket it will be lighten up.
And probably will happen at the same time you read out the screen. Aftere facedown the device or when it hasn't recognized human usage for a while (1 to 2 min.), it should be dimmed to reduce power.
Have you set auto brightness to off at 'settings/ display' or else tried to set 'adaptive display' to 'basic' at 'settings/ display/ screen mode'?
Have you set the AOD to be always on? Or having time specific settings enabled?
Hopefully this will help you out.
Thanks , I use entertainment mode, I set AOD to always, as for light sensor, in dark or bright situations it seems to be brighter or dimmer at random, sometimes I wake up after 2 or 3 hours of sleep antd AOD is very bright!, or the contrary, beeing for sometime outdoors and is dimmed
Which version of AOD did you have installed? Is it custom downloaded from sammobile or something? Maybe force stop the app, or better to clear app data and reboot and/or check if the app has an update. All in app-info
Currently I'm on 8.0.0 and no issues with AOD so far.

I did some research and found something that might work to decrease dimming to 0.
The app (link to Playstore) "priv set" (by: oguzhan yigit) has some powerful settings with it to set on overlay basis.
One thing... You only can use it with root privilege.
The attachment shows the possible setting to decrease dimming while dozing.

The first issue regarding contrast settings is that on 10.2.28 at least, if I set the phone to "standard contrast", sometimes upon waking it, it forgets that setting and looks exactly as if set on "automatic contrast", even though standard is still checked. Just confirmed this as my screen looked rather blue, changed to "automatic" and it remained identical, then I changed it back to standard and it finally got the desired white balance.The point of "standard contrast" is that it should be CONSTANT, not ever changing... I've got the phone 4 days ago (enjoying it overall) and I've got to ask if this has been an ongoing issue or is it new in 10.2.28?
The second issue is that with auto brightness OFF, the phone still bumps to max manual brightness when the sun shines directly on the sensor. It's not as annoying as the first issue but I'd rather it would not do that. This is how the mi 9 behaved since release or just a new bug?
Ultimately, can you guys point me to the most effective way of reporting bugs to xiaomi?
I'm on the same rom version... I don't have any issues with contrast changing like you said but I'm on increased contrast at all times... There's no way of disabling the screen boosting brightness in sun light regardless of auto brightness settings... It's sunlight 2.0 mode and actually boosts the brightness higher then the max on the brightness slider.
