USB drives are so convenient, aren’t they? But you can’t use one with your phone. Well, unless you have an Android and know what USB OTG is.
USB On-The-Go (OTG) is a standardized specification for USB connections that allows a device to read data from a USB connection without requiring a PC. The device is basically becoming a “USB Host”, which isn’t an ability every gadget has.
What can you do with it? For example, if you want to connect your USB drive to your phone, USB OTG can make that happen.
USB OTG is not an Android-specific feature, but that is its most popular use, so it’s what we’ll focus on. Some printers already support it, Microsoft is expected to bring USB OTG in Windows Phone 10, but there’s no sign of Apple allowing this.
The easiest and most reliable way to check if your phone or tablet supports USB OTG is to check the box it came in or the manufacturer’s website.If you can’t find the information there, try checking for your device on GSMArena.com. In the specifications list, scroll down to where it says “USB” and check if the entry lists “USB Host” — those are the magic words you’re looking for.
Another method is to download USB OTG Checker from the Play Store; it’s a free app that you can run to get a quick answer on whether your Android supports the feature or not.
Not every Android device supports USB OTG, it’s something the manufacturer has to enable. This setting is in the phone or tablet’s kernel, the conduit middleman software that lets your hardware talk to your operating system and apps. If your answer is a negative when you use USB OTG Checker, then you might want to consider using a custom Android kernel that supports USB OTG for your device.
