How To Check An Android Phone/Tablet For USB OTG Support

OTG mean On The Go which is a USB feature found on most android phones and tablets today. With USB OTG support you can directly connect a pen drive, keyboard, mouse or external storage to your android phone or tablet via a USB OTG cable. OTG feature is a boon for android phones and tablets because you can copy or move data efficiently by connecting a USB drive to it. Not every android phone or tablet support this OTG. In this tutorial I am going to teach you how you can test/check your phone or tablet for OTG support without using a OTG cable. However do not buy the cable if you are not sure about your phone or tablet’s OTG support. Follow this tutorial and later buy the cable if your phone supports it.

You have to download an android app that will test the OTG support on your phone or tablet. This app is called ‘USB OTG Checker’. Download Here.

Install this app and follow the steps below.

  • Open the app and tap ‘Check Device OS’. This will test whether your phone or tablet has the  USB OTG API or not. OTG API is a code which is necessary for the support. If this API exists on your phone’s OS then the feature is fully supported by your phone. Tap ‘Check’ to proceed.


  • If your phone or tablet has missing OTG API then unfortunately you can’t connect pen drives to it.
Now you have successfully tested/checked your android phone or tablet for OTG support without actually buying the cable. Please not that your phone may not support most USB drives due to low battery power issues because most USB devices require a full 5V DC like external hard disks. Other devices like pen drives, keyboards, mouse, other phones connected in mass storage mode will work without any problems.

    Does my phone really have OTG support?

    1. You should check it by connecting a USB drive via OTG cable. If you use ES file explorer then it will open the OTG disk automatically, otherwise android system will handle it. On connecting the cable a USB icon will appear in status bar. If the icon doesn't appear then your phone doesn't support OTG.
