Hi. I have the same problem on my Xiaomi 12. Have you found any solution ? Thanx.Hello, I switched to HyperOS 3.0 on Xiaomi12(cupid) and I got the following problem: After activating the Alarm Clock, when turning it off, the screen freezes and does not accept any commands. A restart is required via the button. I did a factory reset, but it did not help. Any ideas on how to solve the problem?
