What is USB OTG?

USB OTG (USB On The Go) is a standard that enables mobile devices to talk to one another. Traditionally mobile devices could only connect to a Mac/PC by USB, but USB OTG makes it possible for devices to connect directly to each other.

And that’s not all USB OTG can do. By enabling your device to act as a USB host – that is, to be the boss of other devices that you connect to it – you can use additional hardware such as storage, keyboards or even musical instruments together with your device.

How do I know if my Android device supports USB OTG?

USB OTG has its own logo, which will be on your device’s packaging if it’s supported. If you don’t have the original packaging to hand, you can use your old friend Google. However, if your smartphone was released within the last two to three years, you can almost guarantee it will support it.
