Free up phone memory
Do you need to increase the available phone memory, so you can install more apps or add more content?
You can delete the following if no longer needed:
-
Text, multimedia, and mail messages
-
Contact entries and details
-
Apps
-
Installation files (.sis or .sisx) for installed apps
-
Music, photos, or videos
Copy content you want to keep to the mass memory, to a compatible memory card (if available), or to a compatible computer.
