Fixes issues such as mini lock screen
Today, Apple released the official version update of iOS 14.2.1. It is worth noting that this update is currently only available for the iPhone 12 series. This update solves several bugs that have been recently reported on the new iPhone 12 series.
According to the official announcement, iOS 14.2.1 mainly fixes the following issues of iPhone 12, but it does not rule out that there are other minor updates:
- May not receive some MMS
- Sound quality issues that may exist in the Made for iPhone (MFI) hearing aid device when listening to iPhone audio
- The lock screen on iPhone 12 mini may not respond
- Some dual-SIM devices may lose cellular network connection
The iOS 14.2.1 update is now available for download, and all eligible devices can be downloaded via OTA in “Settings”. To access the new software, go to “Settings”> “General”> “Software Update”.
Last Sunday, foreign media said that quite a few iPhone 12 mini users reported the sensitivity of the lock screen after receiving their phones. When most users use their thumbs to swipe up from the bottom of the lock screen to unlock the device, or when they press the flashlight or camera button on the lock screen, the display does not always recognize pressing or swiping up to unlock. It seems better to use other fingers, and once the iPhone 12 mini is unlocked, the sensitivity problem will disappear.
Also last Sunday, foreign media said that some users of MFi hearing aids reported that their audio devices have some problems when used with iPhone 12, including static noise and difficulty in pairing.
Apple released the official version updates of iOS 14.2 and iPadOS 14.2 on November 5, but 14.1 can be applied to iPhone 6s and newer models.
iOS 14.2 is the first iOS official version update after the iPhone 12 series was released. iOS 14.2 brings more than 100 new emojis. At the same time, the optimized battery charging of AirPods can slow down the battery aging rate by reducing the time for AirPods to fully charge.
