ANDROID What Is USB OTG? Cool Ways to Use It on Android

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 will need an OTG cable or OTG connector.

You can do a lot with this, For example, you might connect a USB flash drive to your phone, or use a video game controller with an Android device.

USB OTG is not an Android-specific feature. But since that’s its most popular use, we’ll focus on using it with Android.

Check If Your Android Supports USB OTG

The easiest way to check if your phone or tablet supports USB OTG is to look at the box it came in or the manufacturer’s website. You’ll see a logo like the one above, or USB OTG listed in the specifications.

Another easy method is to use a USB OTG checker app. There are plenty of such free apps on the Google Play Store, but some are loaded with ads. Easy OTG Checker is a reliable app for this. Download and run it, and you’ll know if your phone supports USB OTG.

Not every Android device supports USB OTG; it’s something the manufacturer has to enable. If you find out your phone isn’t compatible when you use USB OTG Checker, this unfortunately won’t work for you.

What You Need to Use USB OTG

USB-C to USB-A Adapter

Your Android device has a standard micro-USB or USB-C port (our guide to USB cables). However, most USB devices require a full-size USB port. You can resolve that with a converter/adapter.

Specifically, look for a micro-USB or USB-C (depending on what your phone uses) male to full-size USB female adapter—those male and female designations are essential. Amazon carries many such adapters, like the popular Anker USB-C to USB adapter.

t’s also possible to buy flash drives with both micro-USB and standard USB ports, like the super useful Kingston Micro Duo. It doesn’t cost much more than a regular USB drive either, so it’s a pretty sound purchase.

Once you’re ready with USB OTG for your Android device, a world of opportunities opens up. Here are some of the most popular uses.

1. Connect Flash Drives and External Hard Drives

Unsurprisingly, external storage is at the top of this list. Just plug a drive in and you’ll be ready to go. You can then transfer all kinds of files.

Flash drives are the easiest to connect; external hard drives may or may not work. Portable hard drives that draw power from the phone won’t always work, but external drives with their own power source should work just fine.

2. Control Android With Keyboard and Mouse

Android’s open nature makes it easy to connect just about anything. If you want to use your tablet as a laptop, a keyboard and mouse is integral to the experience. You’ll be happy to know that Android works well with most wireless and wired keyboards and mice.

We recommend getting a wireless keyboard and mouse set with a unified receiver, since you only have one available USB connection. I haven’t seen a functional USB hub working over USB OTG.

You should buy a standard plug-and-play wireless set that is compatible with all platforms. However, make sure you don’t buy something that requires accompanying software, like some Logitech devices that require the SetPoint software.

As noted in our detailed guide to connecting a USB keyboard to Android devices, the OS defaults to QWERTY. You’ll need a special keyboard app for other layouts, like Colemak or DVORAK.
