low brightness after unlocking.

Hello! There was a problem on my iPhone (11 pro max) and my wife's iPhone (11 pro) after updating to iOS 14! When unlocking the iPhone, the screen brightness is low, even when it is forced to the maximum value. After re-locking and unlocking the screen, the brightness of the screen works correctly. The problem appears sporadically. No specific scenarios can be identified. No background applications are running. Before the update, everything worked correctly and I faced such a problem for the first time.

iPhone 11 Pro Max, iOS 14

My girlfriend has an iPhone XS and the exact same issue has started with iOS14. Sometimes, when turning on the screen with the power button, the brightness is very low, even though her setting is at like 90%. She has to press the power button to turn off the screen and then press again to turn it on and then the brightness is back at good levels. This was working fine before iOS14. It happens randomly and is very annoying.

I have this same issue too. There's no pattern I can follow to trigger it but it happens multiple times a day. I have an iPhone 11 Pro Max

Hi there. Turning off True Tone setting worked. Phone is stable now but this is a workaround. I wish this issue needs to be acknowledged by Apple and next update should fix it.
