How to Fix Signal Video Call Not Working
If your Signal video calls aren’t connecting or keep dropping, you’re not alone. Many users face common issues with Signal’s video calling feature, but the good news is that most problems have practical fixes. In this guide, we’ll walk you through step-by-step solutions to get your Signal video calls working smoothly again.
1. Check Your Internet Connection
Signal video calls require a stable internet connection to work properly. If your connection is slow or intermittent, calls may fail to connect or drop unexpectedly.
- Switch between Wi-Fi and mobile data: If you’re on Wi-Fi, try switching to mobile data to see if the call quality improves, or vice versa.
- Run a speed test: Use a service like Speedtest.net to check your upload and download speeds. Signal recommends at least 1 Mbps upload/download for smooth video calls.
- Restart your router or modem: Sometimes the simplest fix is to refresh your home network equipment.
2. Update Signal and Your Device Software
Outdated apps or operating systems often cause compatibility issues that impact video calling.
- Update Signal:
- On Android, open Google Play Store, search for Signal, and tap Update if available.
- On iOS, open the App Store, tap your profile, scroll to Signal, and tap Update.
- Update your device’s OS:
- On Android, go to Settings > System > Software update.
- On iOS, go to Settings > General > Software Update.
- Restart your phone: This helps complete updates and clears temporary issues.
3. Verify Signal’s Permissions
For Signal to make video calls, it needs access to your camera, microphone, and sometimes network settings. If these permissions are disabled, video calls won’t work properly.
- Check permissions on Android:
- Open Settings and go to Apps & Notifications.
- Find and tap Signal.
- Tap Permissions.
- Make sure Camera and Microphone are allowed.
- Check permissions on iPhone:
- Open Settings.
- Scroll down and tap Signal.
- Make sure Camera and Microphone toggles are enabled.
4. Clear Signal Cache and Data (Android Only)
If Signal is misbehaving, clearing the app cache or data can help fix corrupted files preventing video calls from working.
- Go to Settings > Apps & Notifications > Signal.
- Tap on Storage & Cache.
- Tap Clear Cache first and test if video calls work.
- If issues persist, tap Clear Storage/Data. Note: This will log you out and delete local data, so back up your messages first via Signal’s settings.
5. Ensure Both Users Have Compatible Versions and Settings
Signal’s video calls require both parties to have updated versions and proper connectivity.
- Ask your contact to update Signal to the latest version.
- Confirm both of you have enabled video calling permissions.
- Try making a test call with a different contact to isolate if the issue is specific to one user.
6. Check Signal’s Server Status and Network Restrictions
Though rare, Signal’s servers might experience outages affecting video call functionality.
- Visit signal.org or check @signalapp on Twitter for status updates.
- Make sure your network isn’t blocking Signal’s ports—especially if you’re on a corporate or school Wi-Fi. Try switching to a different network or using a VPN.
