To free-up memory on your Micro-SD card we recommend that you delete unneeded media. You can remove videos or pictures by connecting your device to a computer and transferring the files. If you’ve already transferred a copy or no longer need the media files, we recommend that you delete them to free-up space.
Go to the media application. You can find files under music, videos, pictures, etc.
Highlight the media you want to delete and display the menu, then select delete.
