Apple's iOS 17.1 update may fix the screen burn-in issue on the iPhone 15 Pro Max.
The screen burn-in issue is caused by the phone's OLED display.
The issue is more likely to occur when the phone is used at high brightness levels for extended periods of time.
The iOS 17.1 update includes a feature that automatically adjusts the brightness of the phone's display based on ambient light.
This feature may help prevent screen burn-in by reducing the amount of time the display is at high brightness levels.
Apple has not officially confirmed that the iOS 17.1 update fixes the screen burn-in issue.
Users have reported that the update has improved the issue, but it is not clear if it has been completely resolved.
