I was struggling with my phone freaking out while doing video chat on either Teams and Duo. Both apps did the same thing and I provided feedback to their developers that it appeared to start on my note 20 ultra 5g when android 11 landed. It happens when you make the video less than full screen. At times the phone is unusable and non responsive to touch.
Today I realized that if I changed my video resolution for the phone display from FHD+ to WQHD+ the freezing stops altogether...
From the device specific reviews I can see this affects many other samsung users. We likely need samsung to fix this since it affects multiple apps.
Anyone else able to test this out?
