Recalibrate auto screen brightness since Android 9 update
Since Andriod 9, my HTC U11 auto screen brightness was not working properly. It kept resetting to an almost useless 9%. There is a recalibration solution posted for Samsung phones that also seems to have worked for my HTC U11. Good luck.
With auto brightness enabled, tape your Galaxy S8 and cover the two sensors that are to the left and to the right of the earpiece.
This will trick the device into thinking you’re in a pitch black room.
Next, switch off the auto brightness feature by bringing down the status bar and moving the brightness bar to the left. Make sure you’re still covering the sensors!
Next, quickly activate the auto brightness feature and then deactivate it again. Keep the sensors covered.
Next, take your Galaxy S8 to a bright lamp or light. Stop covering the light sensors.
Put the brightness on your device to the maximum setting, then switch the auto brightness feature back on.
Your Galaxy S8 will now have had it’s auto brightness sensors recalibrated so that they work more efficiently in dark light, bright light, and everything in between.

Hi People
The Display Automatic brightness Not Working Anymore !
the display brightness doesn't change automatically anymore what ever the light condition in the room was.
in a dark room or bright sun the brightness is the same and not changing.
I have wiped Cache Partition but also nothing happened.
any body have any solution or a fix other than hard reset ?
