iOS 15.2.1 release fixes:
1.HomeKit causes crash issue
Previously, researchers said that if the device name is changed to an infinite number of characters in HomeKit, it will cause the iPhone to go down, and this vulnerability is called "doorLock".
iOS 15.2.1 completely solves this problem, users can not change the name of the device that is too long, and the bug will not be triggered after the upgrade of the previously modified long name.
2. Information issues
Fixed an issue where iCloud Photo Links could not be sent using the Messages app, where in previous versions, iCloud links were mistaken for malicious links, preventing users from receiving messages properly.
3.CarPlay
Fixed an issue where using CarPlay would cause non-responsiveness and unable to enter.
iOS 15.3 Beta 2 did not see any updates visible to the naked eye.
