Troubleshooting issues with downloading media in Signal
Applies to: Signal Messenger (Android, iOS, Desktop)
Last updated: September 2025
Problem
Photos, videos, or documents in Signal fail to download, get stuck, or show errors. Sometimes only certain files won’t download, while text messages work fine.
Solution
Media download problems usually stem from poor internet, low device storage, incorrect app permissions, or data restrictions.
Step-by-step Instructions
Step 1: Check internet connection
- Test another app (e.g., browser, email) to confirm connectivity.
- Switch between Wi-Fi and mobile data.
- Restart your router if using Wi-Fi.
Step 2: Check device storage
- Android: Settings > Storage.
- iPhone: Settings > General > iPhone Storage.
- Free up space if storage is nearly full — Signal cannot save new media without space.
Step 3: Verify date & time settings
- Go to device Date & Time settings.
- Enable Set automatically — incorrect time can block downloads.
Step 4: Check Signal permissions
- Android:
- Settings > Apps > Signal > Permissions → Allow Storage/Photos and Media.
- iPhone:
- Settings > Signal → Ensure Photos and Local Network (if shown) are enabled.
Step 5: Clear cache and restart Signal
- Android: Settings > Apps > Signal > Storage > Clear Cache.
- iPhone: Signal > Settings > Data and Storage > Manage Storage > Clear Cache.
- Restart the app and retry the download.
Step 6: Update or reinstall Signal
- Update via Play Store/App Store.
- If issues persist, uninstall and reinstall (use backups first to avoid losing chats).
Optional Methods or Tools
- If downloads fail on Wi-Fi only, check if your router or ISP blocks Signal traffic.
- Disable VPNs/Proxies — they may interfere with encrypted downloads.
- On Signal Desktop, ensure your phone is online, since it relays downloads.
Best Practices / Tips
- Use Wi-Fi for downloading large media instead of mobile data.
- Clear cache regularly to prevent file corruption.
- Avoid downloading suspicious files — they may contain malware or spam.
- Keep both Signal and your OS updated for better compatibility.
