Something seems to have gone wrong with the gesture that opens the app drawer. The only response is from the lower centre, from which a blue circle rises, about the same size as the fingerprint icon. It stutters and shows the app drawer for a split second. All other gestures work fine including closing/minimizing apps which is a similar gesture.
Reboots haven't fixed it and I'll be annoyed if I have to factory reset. If I have to do that I'll revert to Android 11.
