talidorn , via OnePlus 8 T-Mobile , Dec 22, 2020 : Phone: OnePlus 8 5G Carrier: T-Mobile Software Version: 10.5.23.IN55CB Issue: When enabled adaptive brightness inverts/negative photo the screen. This makes the phone unusable. Watching videos when this happens is horrible as the picture mostly turns electric green. Workaround: Disable adaptive brightness and set brightness to a static position. I'm not sure this is a workaround as I have no access to use of adaptive brightness. I've seen multiple posts similar to this with no clear fix or real solution.
