Nearly all Android devices supported USB connection, but only a few of them comes with On The Go (OTG) protocol feature. In a nutshell, USB OTG allows the phone to connect to a USB peripheral through Micro USB or USB-C port.

Before you decided to buy USB OTG for Android, one thing you should consider figuring out whether the phone supports that type of connection. Google has been released OTG connection since Android 3.1, but only small numbers of the phone come with that feature. The phones manufacturer also ‘didn’t realize’ this new update and remains disabled on their phones.
