  • Open the Settings app.
  • Scroll for Display & Brightness.
  • Check the status of the Automatic setting. If it’s enabled disable it, force restart your device and re-enable it after the iPhone reboots.

iPhone 12 Low Brightness Cause?

Apparently the Automatic Brightness setting could in fact be the trigger of the iPhone 12 low brightness issue! As noticed by reader Gustavo the screen of the new iPhone displays less bright when Automatic Brightness is ON and the same level of brightness is set. Below is a quote from his comment:

“I have an iPhone 12 pro max with this behavior :
– Screen brightness set at 100% with Auto Brightness ‘ON’ and then turn AB ‘OFF’ the screen at exactly same 100% is much brighter!
– Screen AB on at 100% in darker room is less brighter than screen at 100% with AB on in bright room!
If I test exactly the same way with other values in the brightness screen like ( 10%, 20%, 30%, 40%), the same happens!”

Can you replicate the same issue, is this the cause for the dimmed screen issue on your iPhone 12? Use the comments section to share your feedback!

We’re trying to find out if the dimmed screen problem is caused by a bug that automatically enables Reduce White Point in iOS 14, or a bug that is triggered by the Automatic brightness setting. Either way the situation has been reported to Apple and this article has been attached to the report.
