OTG USB Checker

Let’s check if your smartphone can connect directly to an external accessory.

Wondering if your phone/tablet would support a USB OTG device? Some do, some do not. This app will determine that for you. Root not required.

NOTE: This does NOT enable OTG or make any changes, it only CHECKS whether OTG (On The Go / USB Host) is supported or not.
