When you're running out of storage space, you can move a downloaded app and its data to the storage card if the card has been set up as internal storage.
If you need to reformat your storage card, make sure to move each app and its data back to the built-in storage before formatting the card.
Important: Preinstalled apps cannot be moved. Some third-party apps you've downloaded and installed to the built-in storage may also not allow you to move them to the storage card.
Home screen, swipe up and then tap
Internal storage, and then tap
Other apps if you want to move an app from the built-in storage to the storage card.
Or tap the name of your storage card, and then tap
Apps if you need to move an app from the storage card back to the built-in storage.
Tap an app you want to move.
Change, and then tap where you want to move it to.
