Apple has launched a repaired version of iOS 14.2.1, which mainly fixes MMS errors and the iPhone 12 mini’s unresponsive lock screen status.

Of course, more users may be concerned about the greenish screen problem of the entire iPhone 12 series, but this update did not mention the fix for the greenish screen display problem.

iOS 13.3.1

The greenish screen problem should be a display problem. Although Apple can optimize the problem through software, the repair speed may be slower than ordinary problems.

The user can open the iOS device and go to the settings and click on the general software update to find the new version. The specific update content of different devices is slightly different.


  • Some MMS messages may not be received
  • Made for iPhone hearing devices could have sound quality issues when listening to audio from iPhone
  • Lock Screen could become unresponsive on iPhone 12 mini
