Phone Storage Full – What Can I Delete?

Photos, videos, and app data are the most common storage culprits. Steps: 1) Upload photos and videos to a cloud service (e.g. Google Photos or iCloud) and then delete them locally. 2) Open Settings → Storage and check which apps are using the most space – uninstall rarely used apps. 3) Clear app caches (Settings → Apps → Clear Cache). 4) Browse downloaded files in the file manager and delete anything unnecessary. 5) Clean up messenger chat histories with large media files – many apps have a built-in function for this.
