LG camera is entirely camera 1 api but with hidden params there seems to be one for activating dng i think what this does is make use of the rawpictuecallback with the standard callback for jpeg.

This is how the m9 does raw in camera 1 also but they end up using dngwriter from cam2.

Will try decompile apk see what more i can find out
