USB OTG Checker makes it easy to test whether your phone is compatible with USB OTG devices. OTG or On The Go USB devices are devices that can be used on the USB port of your device via a suitable OTG USB cable.

USB OTG Checker does not allow you to do that testing. It will not change your device.

FUNCTIONALITIES
- check the presence of USB Manager
- check the presence of android.hardware.usb.host.xml
- find the list of connected OTG USB devices

IF FOUND TO BE INCOMPATIBLE with USB OTG devices :
It is not fatal. You can probably still make it work. Depending on the step that blocks in the test, you can look on the internet for your phone more specifically. But you will probably need to root your device.
