Camera not working
-
Stock camera is currently not working on this device. When the app is opened, the screen is black for both front and back cameras.
I followed @vince1171 recommendation in the original OP2 forum thread to use gst-droid with no success. I get exactly the same result, a black screen.
Debugging the app, I got some error messages regarding camera detection:
