I have connected a digital microscope to my tablet through the OTG interface and I downloaded several programs to run the microscope but all of them do not work showing me a black screen without displaying the image
What I do, please help me
Note: The tablet from Samsung Galaxy Tab lite: T116NQ and I have connected the webcam but the same problem
Unfortunately a camera isn't a standard USB device supported by Android's stock system, which means that only apps that are coded specifically to use them (think of them like drivers for a PC) can, well, use them.
Are you certain the app you downloaded is compatible with that specific camera or Android OS? Do any other OTG devices like USB Sticks work OK?
The T116NQ doesn't support OTG.
Yes USB Sticks it works and I have tried many programs without interest
