According to Wikipedia, USB On-The-Go (OTG) is a standardized specification that allows a device to read data from a USB device without the need for a personal computer or laptop. However, not all phones have this unique feature, hence the need to find out which phones are USB OTG support android phones. OTG is sometimes referred to as USB Host on some phones.
So, basically, the OTG’s function is to allow your mobile phone to be able to perform the work of the sender or receiver when connected to a removable media such as the pen drive.
Also, to use the otg feature of your phone, you need to have the OTG cable or connector and the OTG Pendrive or USB OTG Adapter that you’ll connect to your phone in order to send files from your phone to the drive or from the OTG Pendrive (On The Go Pendrive) to your phone.
You can try rooting your phone to unlock the OTG feature if the feature does not come out of the box with your Android tablet or phone. Note that this is for those that know the process of rooting phones and what the risks are.
For instance, in some phone brands like Samsung and Sony, the rooting of the phone voids the phone’s warranty.
To check if your device is USB OTG compatible, you can download an easy USB OTG checker app on the Google Play store. Click here to download the OTG app which can help you determine if your Android smartphone or tablet can support this functionality.
One good thing is that the app does not need root to work. Here’s a screenshot of how the OTG checker app looks.
