IOS is freezing after unlocking the screen
Hi! I have a problem: my iPhone 7 plus has got some lags. It happens when I unlock the phone screen by Touch ID. Lags/freezing continue for 4-5 seconds. I don't know how to fix it. My actual firmware is iOS 14. It happens for about 80% of the time. 20% - iPhone works fine. The lags have started from iOS 13. I thought that updating to iOS 14 could fix this issue, but it couldn't. One thing which I have noticed - after unlocking the screen, the lock icon which is placed on the info bar of the screen is visible for about 3 seconds. Probably something is wrong with unlocking the screen by Touch ID. But touch ID works fine. Look at the video: after the first attempt everything works fine, but after the second attempt, the iPhone has been freezing.
