The camera feature doesn't recognize any text on many books. IT focuses the camera and then goes out of focus as if the focus programming is off. Can't use with camera. Google Translate was much better as I merely had to select camera mode and point to what I wanted translated and it would show the updated language in camera view mode. Samsung Galaxy 3 with Android 6.0.1 Too bad this app can't translate Latin. It would have been useful in Rome.
