Thank you for your prompt shipment. I was instructed to install an app called "inskam" on my smartphone, but it's useless. After installing the app called "USB camera", I can use this camera. It's hard to say that the image is clear, but it can be used to search for objects that have entered the gap. There is no complaint if it can be done so far at a low price.
it's working i how usb otg from my samsung note 10+
