If your FireTV is displaying a “critically low on storage” message, it indicates that it has run out of usable space. This issue is common with Fire TV Sticks, which come with only 8GB of storage, offering about 5GB of usable space for apps, games, and caching. Here’s how you can manage and fix this issue:
1. Delete Unused Apps
Over time, you might have accumulated apps that you no longer use. These apps can take up significant space. To delete them:
- Go to Settings > Applications > Manage Installed Applications.
- Select the apps you don’t use and choose “uninstall”.
- Note that built-in apps like Amazon Kids, Amazon Music, and Prime Video cannot be uninstalled.
2. Clear App Cache
Apps cache data to enhance performance, but this cache can grow and occupy a lot of space. To clear it:
- Navigate to Settings > Applications > Manage Installed Applications.
- Click on an application and select “Clear Cache”.
- Doing this for frequently used apps can free up a considerable amount of space.
3. Use External Storage
When you’ve maximized the options to reclaim your existing storage, the next step is to expand it with external storage:
- You’ll need an OTG (On-The-Go) cable or adapter.
- Attach a USB-powered FAT 32 formatted flash disk or portable hard drive.
- Recent updates to FireTV allow app installations directly on the USB drive.
- Ensure the external storage device gets enough power from a USB wall charger or your TV’s USB ports.
4. Updating Firmware
Outdated firmware can sometimes cause storage management issues. Ensure your FireTV’s firmware is updated to the latest version. This can also bring new features and bug fixes that optimize storage usage.
5. Factory Reset as a Last Resort
If all else fails, consider a factory reset. This will erase all data and return your FireTV to its original settings. Only use this option if you’ve backed up important data and are comfortable reinstalling and reconfiguring apps.
6. Regular Maintenance
- Regularly check your storage space under Settings > My Fire TV > About > Storage.
- Keep an eye on the size of app caches and routinely clear them.
- Be mindful of the number of apps you install, especially large ones like games.
7. Understand the Limitations
Being aware of the storage limitations of your FireTV can help you manage space better. Avoid installing apps that you won’t use or that are particularly large. Consider streaming content instead of storing it on the device.
In conclusion, managing storage on FireTV requires a combination of regular maintenance, judicious use of apps, and possibly expanding storage with external devices. By following these steps, you can ensure your FireTV operates smoothly without running into storage issues.
