Screen doesn't turn off on its own

[kavuky]

Good morning, it has happened to me a couple of times in the last few days. The screen of iPhone 12 Pro does not turn off on my own. Let me explain, I mean when I'm on the lock screen, my phone lights up, I don't touch anything and it doesn't turn black as it should happen. If I restart the phone it works without problems until it happens again, since yesterday twice, I have version 15.2.1

Thanks

Maybe try Settings->Display & Brightness->Auto-Lock set to Never, restart your phone, set Auto-Lock again. If that does not solve the issue connect your phone to a Mac computer, do a backup to the computer, then put for phone in a Recovery Mode while connected to a Mac computer and do an Update. This will refresh the OS on your phone without touching your user data. Then you do a restore from backup on your computer.

I'm experiencing the same issue here. I noticed that the screen will never dim let alone turn off when the control center is open. I don't remember such behavior in iOS 14, so it looks like a bug to me.
