[AC Question]

Hello. That's it?
Well let's start guessing what the problem is.

The screen shutter button to take a shot does not appear for the main/back camera, only the front?

You could try clearing the cache and data on the camera app or the one you downloaded. You could also do a system cache wipe in Recovery mode.

You would need to register and let us know the exact issue and the device.
