My Samsung Galaxy Note 2 came with 8 gigs of internal memory. I discovered that apps can only be written to the internal 8 gigs of memory so I didn't want to fill up the internal memory with pictures, videos, music, etc.  I purchased the 64 GB San Disk Ultra MicroSDXC Class 10 card. I found a video on youtube to learn how to insert the card since I could find nothing on it in the phone's user guide.  It's real easy. Turn the Note phone off. Remove the Note's back plate. You see a plaque saying SD card in the upper left quadrant of the phone. Simply place the microsd card face up with the metallic pins facing down and towards the right into the depressed slot area to the left of the SD card plaque. Then slowly and gently slide the microsd card under the plaque until it clicks. If it isn't in correctly, it will tend to move back out from under the plaque. Do not force. Replace the back plate on the phone. Turn the phone on.  Go to settings, storage.  At the bottom of the page, you will see SD Card.  If the microsd card was inserted correctly, you will see the additional GBs of storage displayed there.  You will also see Reformat SD card and Remove SD card.  Use these settings to erase data from the microsd card, and to remove it from the phone.  Do not try to remove the microsd card from the phone without first activating the Remove SD Card setting.  You can damage the card and the phone.  The card came quickly and San Disk is a reliable brand. It's great to have the Class 10 rating too.
