"iPhone 14 Pro Max screen constantly dims when locked: My iPhone 14 Pro Max recently started to constantly dim by itself, never happened before. It dims during nights and days, no matter what type of light or no light - it always dims, it happens when it’s locked , it doesn’t do it when it’s in use. The phone is up to date. Tried every option in setting , nothing helps. Any suggestions?"
