USB drives are convenient, but you can’t use one with your phone. Well, unless you have an Android phone and know what USB OTG is.
USB On-The-Go (OTG) is a standardized specification that allows a device to read data from a USB device without requiring a PC. The device basically becomes a USB host, which isn’t an ability every gadget has.
You can do a lot with this, For example, you might connect a USB flash drive to your phone, or use an old video game controller with a tablet.
USB OTG is not an Android-specific feature. But since that’s its most popular use, we’ll focus on using it with Android.
