Insert a media card
If you want more storage for pictures, videos, music, and documents, you can insert a media card (microSD card).
Position your device so you can see the back cover and the top of the device.
Release the media card tray by pushing the tip of the tool (provided in the box) into the hole on the top-left side of
your device. If you don't have the tool that came with your device, you can also use a paper clip.
Setup and basics
Pull out the tray completely and set it on a flat surface.
Hold the media card so that the metal contacts are facing down and the notch is aligned with the notch in the tray.
Put the media card in the tray.
Push the tray back into the slot.
