I have never had any issue with my Flip 5 until now. Ever since update One UI v6.0 I have this chronic issue that when I flip my phone open the screen will stay black but the touch points still seem to be working and reacting in the background. I close it and open it multiple time with no change. The front screen works and tells me if I am unlocking of locking my phone with the lock notification but in the open mode the phone screen remain black/dark. Also the phone seem to think that it is still closed because the volume button will stay in reverse (down is up, and up is down) as if it was still flipped closed.

The only way I have found to resolve this issue is a full hard boot pressing volume down + lock button simultaneously  until it reboots. 

This issue is greatly impacting my user experience and ability to take important calls.
