S23 ultra screen dimming

[Michaelray365]

Does anyone know how to stop the screen from dimming randomly? Screen on time or how long the phone has been on doesn't seem to matter, the screen randomly dims by about 20-30 percent.

Do you have adaptive brightness turned on? The phone will detect ambient light and dim or brighten your screen accordingly.

I have

Could run the diagnostic test

[Michaelray365]

I have. It says everything is fine

[meself]

If the screen is flickering I would take to a repair center may need to get repaired

[Michaelray365]

It doesn't flicker, it just dims. Otherwise it's working fine
