Android Question Using CameraEX

[joilts]

Hi to all,
I have a project in production with almost 28k users (total downloads on play store). All works fine to almost all them, but to some user, when trying to take a picture an error occurs. I'm using CameraEX to take picture and the message returned is bellow. Does any one has a clue why it happens and how to fix?

= (RuntimeException) java.lang.RuntimeException: takePicture failed -

Are you changing the camera settings? Maybe those devices don't support those settings.

It is also possible that these are random fails that you can do nothing about them as the camera on some devices are not 100% reliable.
