The Motorola Droid RAZR smartphone has an expandable SD card slot. Here’s how to find the slot and insert and remove the SD card.
1. Power the device off, or go to Settings > Storage > Unmount SD card and wait for the card to unmount.
2. Open the SD card cover located on the lower left side of the device.
3. On the bottom part of the slot, you should be able to see the SD card. Gently push it inward and the card should pop out of the slot where you can remove it.
4. To insert the SD card, slide it into the bottom slot with the contacts facing upward (toward the screen side) until you hear it snap into place.
