Today Apple released iOS 14.2.1, but this time it is only for the iPhone 12 series, namely iPhone 12 mini, iPhone 12, iPhone 12 Pro and iPhone 12 Pro Max. For the time being, iOS 14.2.1 is only limited to the new iPhone 12 series, and users can update via OTA.
The new version mainly fixes the problem of receiving MMS earlier and the problem of not being sensitive to the iPhone 12 mini sliding up to unlock the screen. In addition, it also solves the problem of poor sound quality of iPhone listening devices.
Earlier, some users said in the discussion forum that it is difficult to unlock using iPhone 12 mini . When users dial up with their thumbs, the screen does not respond, sometimes even tapping pause or playing music does not respond.
