Samsung Galaxy Note 2 MicroSD Card Replacement

Take the end of the stylus and pull it from its slot.

Push a plastic opening tool (or, if you don't have one, use your fingernail) into the small opening on the left side of the back camera (near the power button) to pry open the back cover.

Take the corner of the back case closest to the small opening between your fingers and separate the back case from the phone.

Press the microSD card (if you have one) deeper into its slot with the flat end of a spudger (or your fingernail) until you hear a click.

After the click, remove the spudger to release the card. The card will pop out of its slot and you will be able to extract it.

For reassembly, you'll need to press the card back into its slot until you hear a click.
