Phone says storage is full
This happens to almost everyone sooner or later, and you can usually free up plenty of space in a few minutes without losing anything important.
Be careful: Before deleting photos or videos, make sure they are backed up somewhere else (cloud or computer). Once the Recently Deleted or Trash folder is emptied, they cannot be brought back.
What to do
Step 1: Open Settings (the gear icon) and tap Storage. On some phones it is under System or Battery and device care.
Step 2: Wait for the list to load. It shows what is using the most space, such as apps, images and videos.
Step 3: Tap Apps, look for apps you no longer use, and uninstall them.
Step 4: Open the Files app (or My Files), go to Downloads, and delete old files you don't need.
Step 5: Open your photo app (Google Photos or Gallery), go to the Trash or Recycle bin, and empty it.
Step 6: Restart your phone so the storage number updates.
Still stuck? If you still can't free enough space, a phone shop or a tech-savvy friend can help you back up and clear things safely, or ask Fix It Fox.
