Connect a USB mass storage device
You can use a USB On-The-Go (OTG) adapter to connect your phone to a compatible
USB memory stick or hard drive. For example, you can save your photos on a USB
memory stick without needing to connect to a PC.
Connect a memory stick
1 Connect the micro-USB end of the USB OTG adapter (available separately) to the
micro-USB connector in your phone.
2 Connect a memory stick to the USB OTG adapter.
The Files application opens, and the memory stick is shown as a mass memory.
Copy a file
In Files, select and hold the file you want to copy, then select the option you want and
the memory and folder you want to copy to.
If you connect a hard drive that requires more power than your phone can supply, an
error message is shown. You need to connect an external power source to the hard
drive.
