Crash on Athesia SPA43LTE when using the legacy API camera on the demo app.

[VincentKobz]

java.lang.RuntimeException: Fail to connect to camera service java.lang.NullPointerException: Attempt to read from field 'int android.graphics.Point.x' on a null object reference

This crash occurs when trying to access the scanner camera of the Athesia SPA43LTE using the button on the demo app. The camera API used is the legacy Camera of android.hardware. When the camera is instantiated automatically (when it is the only provider available), this crash does not occur.
