When your phone says storage is full

A “Storage Full” message means the phone is out of room — so it won’t take new photos, install updates, or sometimes even open apps. The good news: it’s almost always photos and videos filling it up, and you can clear space without losing them.

First: back up your photos (so freeing space is safe)

Turn on automatic backup, then it’s safe to remove the copies hogging your phone:

• iPhone: Settings → tap your name → iCloud → Photos, and turn on iCloud Photos. (Optional: turn on Optimize iPhone Storage so full-size photos live in the cloud and the phone keeps smaller copies.)
• Android: open Google Photos → your picture (top right) → turn on Backup. Then tap Free up space and it removes the copies that are safely backed up.

iPhone — clear the space

1. Go to Settings → General → iPhone Storage. The bar shows what’s using room.
2. Use the suggestions at the top (e.g. Offload Unused Apps — keeps your data, removes the app).
3. Empty the trash: Photos → Albums → Recently Deleted → Delete All. Deleted photos still take space for 30 days until you empty this.
4. Delete a few big videos and apps you don’t use.

Android — clear the space

1. Settings → Storage (or Battery and device care → Storage on Samsung).
2. Tap Free up space / Clean up.
3. In Google Photos, after backup, tap your picture → Free up space.
4. Clear out the Downloads folder and apps you no longer use.

Tip

Photos and videos are nearly always the culprit. Backing them up (above) and then freeing space usually fixes it in one go — and your pictures stay safe in the cloud.

If it’s still full

1. Did the backup finish? Don’t delete photos until it says backed up — on Wi-Fi this can take a while.
2. Restart the phone after clearing space; it sometimes needs that to catch up. See Restart anything.
3. Still jammed? Text Stephen — he can look at what’s using the space with you.
