This doesn't permit to scan any code.
Is there any solution to this?

What type of camera is camera id 2 ? Because that one seems to be missing?

Is this a USB camera?

The phone have 2 cameras on the rear and one on the front, sincerely I don't know why the id camera n. 2 is missing.

However we have 5 phones of the same model (UMIDIGI) ehich have all the same issue.
