Fix a video call that freezes
We'll check bandwidth and network stability, reduce video quality or turn off video, rule out camera or codec issues—or tell you when to contact support.
What you'll need
- Video call app (Zoom, Teams, Meet, etc.)
- Access to device and app settings

- Follow this guide Work through the full procedure from bandwidth to camera.
- Check bandwidth first You want to confirm you have enough bandwidth for video.
- Reduce quality and free bandwidth Bandwidth is limited and you want to reduce video quality or close other apps.
- Camera and codec Bandwidth is fine and you want to check the camera or try a different codec.
- When to contact support The call still freezes after all steps.

Steps
Goal: Confirm you have enough bandwidth, then isolate the cause—quality, camera, or codec.
- Run a speed test at fast.com. Video calls need at least 1.5 Mbps up and down; 2 Mbps or more is better.
- Good: At least 2 Mbps up and down; proceed to Reduce quality and free bandwidth.
- Bad: Less than 2 Mbps—reduce video quality, close other apps, or fix the network. See Fix Wi-Fi that drops or is slow.
Check bandwidth first
Goal: Confirm you have enough bandwidth for video.
- Run a speed test at fast.com. Video calls need at least 1.5 Mbps down and up for standard quality; HD needs more.
- Good: At least 2 Mbps up and down. Proceed to Reduce quality and free bandwidth.
- Bad: Less than 2 Mbps—reduce video quality or fix the network first.
Reduce quality and free bandwidth
Goal: Free bandwidth and reduce video quality to stop freezes.
- Close streaming, large downloads, and cloud sync. In the call app, lower the video resolution or turn off video and use audio only.
- Good: Call no longer freezes.
- Bad: Still freezes—proceed to Camera and codec.
Camera and codec
Goal: Rule out camera issues and try a different codec.
- Confirm the camera lens is not covered and the device is not overheating. Try a different codec in the app settings if available. If one app freezes, try another (e.g. Zoom vs Teams).
- Good: Call no longer freezes.
- Bad: Still freezes—contact support with the speed test result and freeze pattern.
When to get help
Contact the call app support or your ISP if:
- The call still freezes after checking bandwidth, quality, camera, and codec.
- Freezes happen only on one network (e.g. work Wi-Fi) but not others.
- You have sufficient bandwidth (e.g. 10+ Mbps) but the call still freezes.
Verification
- The video call runs smoothly without freezes or stutters.
- Video and audio stay in sync.
- No pixelation or long pauses.
Escalation ladder
Work from the device outward. Stop when the problem is fixed.
- Check bandwidth Run speed test; need at least 2 Mbps up and down.
- Free bandwidth Close other apps and stop downloads.
- Reduce quality Lower video resolution or turn off video.
- Camera and codec Check camera; try different codec or app.
- Contact support Provide speed test result and freeze pattern.
What to capture if you need help
Before calling support or posting for help, have these ready. It speeds everything up.
- Speed test result (up and down)
- Call app and version
- When freezes occur (pattern)
- Steps already tried
Do you have at least 2 Mbps up and down?
Run a speed test at fast.com. Video calls need sufficient bandwidth.

Reduce quality and free bandwidth
Did reducing quality help?
You can change your answer later.
Free bandwidth and reduce quality
Other apps and high quality can cause freezes even with good bandwidth.
Did freeing bandwidth and reducing quality help?
You can change your answer later.
Check camera and try different codec
Did camera or codec change help?
