After iOS 15.2, the iOS 15.3 update was actually to be expected, but possibly due to too many complaints, Apple pushed in an interim update. At least it became necessary to publish another update for fixes. Now is iOS 15.2.1 there, with which some errors should disappear.
Update iOS 15.2.1: Which bugs are fixed?
In the last few months, users discovered some problems that the update has now corrected. For both iPads and iPhones, iOS 15.2 resulted in an iCloud link sent photos not loaded became.
In addition, Carplay had its pitfalls because of the use of some Apps on the iPhone stopped responding. These errors have now been fixed with iOS 15.2.1.
Reported very specific problem to Apple
What was special, however, was a mistake that Trevor Spiniolas had found (via Golem). Even if the implementation of the error is very unlikely, the consequences are all the more astonishing. If a HomeKit device is given an extraordinarily long name of several hundred thousand characters, iPhones and iPads will no longer work.
The only solution so far has been to reset the Apple device, but users still had to wait and see. If you didn’t do this and logged back into your iCloud immediately after resetting, the error often occurred a second time.
Security expert Spiniolas believed that this problem could be exploited by ransomware. However, after Apple initially did not react and postponed the fix, it made the grievance public. Now iPads and iPhones with iOS 15.2.1 are largely secure again and Carplay and iCloud services are initially error-free.
It might not be long until iOS 16 either, the Apple update could bring a whole new way of operating iPhones. Some iPhones and iPads should never be able to download iOS 16.
