This application is a handy tool to help you detect if your device supports USB OTG (universal serial bus over-the-goggle) functionality. It was created for android devices that support this technology.

There are no issues in using this app and it is a really useful app. This is because it uses standard USB ports and drivers that are already installed on your device.

However, this app is not the most accurate. It might generate false positives and negatives which means that the device might not support it and might be compatible with it.
