USB OTG is a very useful feature for smartphones. This feature can be seen in almost every modern smartphone. So let’s see what USB OTG is

USB OTG – (USB ON-THE-GO) is a standard feature that allows a device to read or write data from a USB device! The device becomes a USB host. For example, you can plug a USB Pen drive into a smartphone via OTG cable. Then you can access the pen drive’s files via the mobile phone file manager app. Also, you can copy any file to a pen drive from your smartphone’s internal storage.
You can do a lot with this, but basically, you need two things
- USB OTG support smartphone
- USB OTG cable / adaptor
Before you buy OTG Adaptor/cable simply check your smartphone exactly supports the USB OTG feature, otherwise, your money will be wasted!
The easiest & fast way to check if your device support USB OTG is to look at the specifications at the box it came in, or ask the customer care hotline & check the manufacturer’s website. You’ll see a nice logo like the one below, or ‘USB OTG’ written on the specification list.

If the above method does not work for you then this method is suitable for you. Go to the Google Play Store. Go there and type “USB OTG Checker”. Now you can see thousands of apps. You can test with any of these apps and here is the app that worked for me. Download & run it then you can see if your phone support USB OTG or not, like this!
Congratulations if your phone supports USB OTG!. Now you have to buy a USB OTG adapter that matches the USB port of your phone. There are two types of USB ports are available
- Micro USB OTG adaptor
- USB Type C OTG adaptor

3. Play Video or Music From Portable DVD Player
Much like Mouse, a keyboard with a standard plug-and-play USB works well with a smartphone via OTG. But this time you need to install a small app on your phone.

You can play videos, music without transferring files to a smartphone

This popular method is called reverse charge. This method allows you to charge your battery from your friend’s phone when your phone’s battery is low.

All you need for this is your charger cable and USB OTG adaptor.
8. Use USB Fan With Android (Not Recommended)
USB fan is also available in the market and can be connected to the phone via OTG. But I do not recommend connecting these devices to the phone.
This is because if these motors short circuit in any way, there is a risk of damaging our phone.

9. Connect and produce good music with musical instruments

Newer printers have Wi-Fi capability. But older printers do not have Wi-Fi, so a USB must be connected to a computer. When you do not have a computer, you can connect your phone via USB OTG to take advantage of this printer.
NOTE-But not all older printers support OTG
