There are several actions you can take to help free up space on your phone:

1. Identify the amount of space that is being taken up by each app on the device. You can navigate to Settings > General > iPhone Storage to make this assessment.
2. Move photos, videos, and other files to the cloud. You can use a cloud-based storage service, such as iCloud, Google Drive, or Dropbox, to ensure that all of your important files can be accessed from any device.
3. Delete large files, such as videos and old photos, that are no longer needed.
4. Uninstall apps you no longer use as they may still be taking up storage space.
5. Audit subscribed media services and accounts for subscriptions that are no longer needed.
6. Update your device to the latest software version as they can help free up space once installed.
