Storage card
Use a storage card to store your photos, videos, and music. When you need to free up
phone storage space, you can also move certain apps to the storage card, if the apps
support this feature.
The storage card is optional and sold separately.
§ Moving apps to the storage card doesn't back up the apps. If you do a factory
reset, your phone loses the apps. You'll need to reinstall them.
§ When you remove the storage card and insert it in another phone, the apps on the
storage card won't be installed automatically to the other phone. You'll need to
reinstall them.
