New iPhones and new iOS will naturally have new bugs (falls). Before many Pro users look forward to iOS 14.3, which can use ProRAW, Apple has launched a small version update of iOS 14.2.1 of just over 100 MB in response to various minor issues that have recently occurred with iPhone 12 and iOS 14. Not surprisingly, the main thing is to correct various problems – the iPhone 12 mini was reported to have touch unresponsiveness not long after it went on sale, and it soon brought a solution through this update. Continue reading the text of the report that the iPhone 12 mini lock screen unresponsive issue has been resolved in iOS 14.2.1.

The iPhone 12 mini lock screen unresponsive issue has been resolved in iOS 14.2.1
Although the iPhone 12 mini has a relatively small battery, so it relies more on mobile power than other iPhone 12s, but the feel that moved iPhone 5 users and the classic Apple design of the iPhone 4 still gave us a pretty good experience during the unboxing review. However, it may be because Apple has introduced a 5.4-inch full screen for the first time. It seems that the iPhone 12 mini will inevitably encounter some software and hardware coordination problems in the early stages.

Fortunately, Apple quickly provided a solution through updates. In the list of the latest iOS 14.2.1 minor updates, you can see the correction to the iPhone 12 mini “lock screen may not respond” problem. In addition, we have previously seen sound quality problems with MFI hearing aids that should be encountered by all models, and they have also been solved in this update.

Interestingly, the situation fixed in this update also includes a problem that “some MMS messages may not be received.” It seems that not many people have reported this (or is it because the information was really leaked, so it was not discovered at all? XD), but since they are all included in the iPhone problems that have been solved this time, I believe there is no need to worry. This update has officially started to be pushed. Although small updates like this are usually less likely to cause problems, it is recommended to make a backup before updating.
