I have heard that iOS 15.4 has a good experience, just yesterday morning a few colleagues in the office are updating iOS 15.4 Beta3, I also followed the trend, but in the past two days of use, I found these three problems.
First of all, talk about its advantages, I came up from iOS15.3, before I did not experience the mask without taking off the face to unlock, upgrade iOS15.4 Beta3 also want to experience this function, because the reputation is really good. After the upgrade, this function is really amazing, wearing a mask and not wearing the unlock speed is almost the same, I have tested 26 times in succession, the unlock success rate is 100%, and at least 20 times to unlock the very silky, as the third beta version can have this effect, very good.
But in the two days I used, I also found that iOS15.4 Beta3 has three problems, first, this version is more heat than iOS 15.3, in the iOS 15.3 version, my iPhone 12Pro in a long game or video state will appear warm, but after upgrading iOS15.4 Beta3, there will be heat in standby, although it is only warm. But this has not happened before. Second, iOS15.4 Beta3 set the ringtone of the garage band, can not set the ringtone, although this function is not commonly used, but found to be somewhat embarrassing.
Fortunately, the mask of iOS15.4 Beta3 is really easy to use, so I personally feel that the above two problems can be endured, and I look forward to the official version of iOS 15.4 to be more stable.
