not Work at a all
Doesn't work just like the rest of them
I tried about a dozen similar apps out for endoscope-to-android use and this is the first one that worked out for me so I am giving it 5 stars! One thing to keep in mind, after you exit the app make sure the window is also closed in your task mgr or the app may not open correctly the next time.
Didn't work with my camera
Doesn't work at all with my otg camera.
