I have the same problem, made a fresh instal, and still after half a day it does not work. Did not update to hyperos to see if it will work.

For me it works but it will stop working after a few days. To fix you have to go into settings and turn rear display on and off again. Lots of bugs for older phones, still trying to get my HDR working properly. And I have ghost touches on navigation buttons of mi 11 ultra.
