After upgrade from e/OS/ 3.0.4 to 3.1.1 the Acces to the camera from different browsers (not from e/OS/ browser nor from Brave) is not possible on Fairphone 6.
Hence video identification apps could not be used.
On my old Fairphone 3 with e/OS 3.1.1 it worked with both browers.
Please support. Thank you.
