Which system version is your iPhone currently in? In the latest news, Apple has closed the verification channel for the iOS 14.7 system, which means that users of lower versions will only be able to upgrade to iOS 14.7.1. At the same time, users who are already the official version of iOS 14.7.1 will not be able to downgrade.
It is reported that iOS 14.7 was released in mid-July, and iOS 14.7.1 was just launched last week. The changes in iOS 14.7 include the addition of support for Magsafe magnetic external batteries, and the main changes in iOS 14.7.1 include the accidental failure of Touch ID iPhone unlocking Apple Watch and the repair of a very important security vulnerability.
At present, Apple has not yet started the Beta work of iOS 14.8, and it is still unknown whether there is this version. For the iOS team, the top priority will be iOS 15. After all, if nothing else, it will be normalized next month.
