Short answer: go to Settings → Applications → Manage Installed Applications, choose the app, then select Clear cache. Repeat for apps that are slow or freezing. Clearing cache is safe and does not log you out.

Clear cache vs clear data
| Clear cache | Clear data | |
|---|---|---|
| What it removes | Temporary files | All app data and logins |
| Logs you out? | No | Yes |
| When to use | Slow or glitchy app | App still broken after clearing cache |
How to free up storage
- Check space: Settings → My Fire TV → About → Storage.
- Uninstall apps you no longer use.
- Clear cache on the biggest apps.
- Restart the stick after cleaning.
How often should you clear cache?
Only when an app is slow, freezing or showing errors. There is no need to do it every day.
Still slow?
Older Fire Sticks have limited memory. If apps are still sluggish, see which Fire Stick to upgrade to or our Firestick troubleshooting guide.
