Every time I get blinded by this I wonder if it's really necessary at all...I can turn the brightness up myself if the QR code doesn't scan.
Has anyone else noticed the weird interaction between apps turning the brightness to the max and the system’s auto brightness? I’m not an iOS developer, so I don’t know about the relevant APIs. But every time an app changes the brightness to display a QR code, it seems to do so by retrieving the current brightness, turning it to the max, and when it’s done, setting it back to the old value. The problem is that iOS seems to register the brightness change as user initiated, and changes auto brightness behavior. After a few uses, auto brightness will no longer adjust the display to the minimum brightness, even when you’re in complete darkness.
Fixing this used to be easy. Just go to display settings and toggle auto brightness off and on. Then Apple decided to move the toggle under accessibility. Now it’s Accessibility -> Display & Text Size and scroll all the way to the bottom.
