Ever wanted to access some files from an external storage device such as USB flash drive on your Android device? Well, here is some simple steps to check or connect an external device to your Android device.
First, if you do not know if your device is OTG compatible or not, head over to the Google Play Store and download an app to check:
If your device is OTG compatible, then you can proceed and find an adapter or device that allows you to connect a USB device to your phone such as these sort of cables/adapters or flash drive that has a built in port for Android phones:
Micro USB to OTG USB adapter
USB-C to OTG USB adapter
Flash drive that might be compatible with your phone and no need to carry the adapter
Connecting a device to your phone is easy once you have the accessory you need.
1. Connect the USB OTG Cable (or flash drive if you have the ones that are made for phones also) to your phone's USB port.
2. Connect the external device of your choice into the OTG Cable.
That's pretty much it. On most phones, there should be a File Manager installed already and you can find it most likely in your App Drawer and access your storage device from there to view your documents, videos, music, etc.
When you're done using the external device, be sure to properly remove it by swiping down the notification and tapping on the USB mass storage from the notifications or go to Settings -> Storage -> Unmount the external storage device.
