How to Use OTG Feature of Smartphones

USB On-The-Go (OTG)

USB On-The-Go (OTG) is a standardized specification that enables a device to read data from a USB device without the need for a PC. The device essentially becomes a USB host, which isn’t a feature that every device has. An OTG cable or OTG connector is required.

This allows you to do a variety of things, such as connect a USB flash drive to your phone or use a video game controller with an Android device.

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

USB OTG in Android Smartphones

Your Android device is equipped with a standard micro-USB or USB-C port. Many USB devices, however, require a full-size USB port. You can solve this by using a converter/adapter.

Look for a micro-USB or USB-C (depending on your phone) male to full-size USB female adapter—-both the male and female designations are critical.

It’s also possible to purchase flash drives that have both micro-USB and standard USB ports, such as the extremely useful Kingston Micro Duo. It’s also not much more expensive than a standard USB drive, so it’s a pretty good buy.

Here are some of the most common OTG Uses:

  1. Connect Flash Drives and External Hard Drives
  2. Play With Video Game Controllers
  3. Control Android With Keyboard and Mouse
  4. Print Directly From a Printer
  5. Control Your DSLR Camera
  6. Directly Transfer Photos From DSLR to Android Phone
  7. Connect and Play Music Instruments
  8. Record Audio Directly to Your Phone
  9. Connect and Access the Internet via Ethernet Cable
  10. Reverse Charge Your Phone Android Phone
