[How To] Using An SD Card As Internal Storage - ZTE MAX XL
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.
1. From home, tap Apps > Settings.
2. Tap Storage.
3. Tap the SD card name below Portable storage.
4. Tap Format as internal, and then tap Erase & format to confirm.
5. The phone will prompt you to move your photos, files, and other data from the phone storage to the SD card. Tap Move now or Move later and tap Next. Follow the onscreen instructions to continue.
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.
6. Tap Done
