Check USB OTG compatibility
If you are not sure about the 100% compatibility of your handset, then there is an application that lets you use USB if your smartphone allows peripherals to be connected directly to the listener that watches peripherals on the way into OTG. We're talking about a USB OTG Checker.
How does it work?
This small application was only detected in the smartphone file android.hardware.usb.host.xml that function was not found in the USB administrator or unnecessary. And this is a little tool and a little not. The device application does not have to be incompatible to solve the problem.
But that doesn't mean the smartphone supports USB OTG, the work you want to connect doesn't go peripheral. It also depends on any kind of lock and driver. Users must test it.
Requirements and additional information:
- Minimum operating system requirements: Android 4.1.
