Use an SD Card as Internal Storage

You can use an optional SD card as an extension of the internal storage and save data and media files on it. This requires formatting that erases all data on the card and after that the card will only work in this phone. If you move the SD card to another device, it needs to be formatted before it can be used.

CAUTION! As part of the internal storage, the SD card may have data on it that is necessary for some apps to function normally. Therefore, do not remove or replace the card randomly.

Set Up the SD Card as Internal Storage

Before using the SD card as internal storage, you need to set the card up.

  1. From home, tap Apps all apps icon > Settings settings app icon.
  2. Tap Storage.

Note: If you move files and data to the SD card, it will be used to save new apps data and personal data (such as photos and videos) and only the SD card is accessible from a computer. If you choose not to move, new apps data and personal data is saved to the phone storage and the SD card is not accessible from a computer.

  1. Tap Done.

Move Data between Internal Storage and the SD Card
