A free app for Android, by DevAppliance.

If you are looking for a tool to help you identify whether or not your phone is compatible with the on-the-go (OTG) USB interface, you should be very careful with the tools out there.

For many, it’s a simple matter of checking your phone’s specifications and finding out if it is compatible or not. But, as we all know, things can go wrong. To avoid the trouble, you should make sure that you have an OTG-compatible device.

This is why,  DevAppliance created this application, which will help you check the compatibility of your device with the on-the-go (OTG) interface. This app checks for the presence of an OTG interface on your device. This app is more than a simple tool.
