Android Question Camera2 Always fails to use the back camera

https://www.b4x.com/android/forum/threads/camera2-new-camera-library.83855/#content

Hi, i followed the tutorial and try the example of "Camera2", but this always fails on the back camera for photos.... not for videos.. in videos I can use the back camera.

Others librarys works with the back camera too.

So.. Anybody know this problem?'

Thanks
