Ok guys not a show stopper by any means but something I will report to Apple. However, as it is so small I think I could be waiting for sometime for a solution. Basically, after several days of using the phone after the update from the locked screen using the apple swipe up from the bottom to open the screen the phone acts normally. If however, I use my custom gesture to open the phone VO hangs for about 3 seconds then plonks me in the status bar. As I say doesn't happen immediately after updating so it is a strange one. A hard reset does solve it again for several days. Using iPhone 13 pro.
