Hi Ryan,

Would you be able to use the latest Beta version? There have been a lot of changes since Alpha06 and would be helpful to know if you still see the same issue in Beta01. Thanks!

Hi Ryan,

Does your phone have a usb camera enabled ?   Are you trying to open a usb camera or just a built-in camera ?

Hi Dmitry, 

Unfortunately,  CameraX does not support external cameras for now.  will keep you posted if we add the support of external cameras.
