About 2017 Android Endoscope, USB camera Android App

There are certain requirements so you can connect your gadget to the external USB camera (see below).
1) Check that your gadget can support USB OTG. This means that you can connect different peripheral devices (e.g., USB flash drive, USB-disk, etc.) to your gadget via USB.
2) External camera must support UVC standard. This means that it can be used in Android.
3) A high-quality micro USB OTG cable must be used to connect the USB camera and gadget. This means that this cable should not be very long - the shorter the cable, the better.

Why the screen is black?
Let's say your gadget supports the OTG function and the USB camera is compatible with ANDROID. But the screen remains black.
Why? The reason may be in the wrong choice of the micro USB cable (see the figure below). The cable should not be very long - the shorter the cable the better.
