I have a Lenovo Ideapad Y70 with a built in camera and Windows 10 Home. My company uses MS Teams and I can log in and see and hear everyone and they can hear me, but my face is frozen or doesn’t appear at all. I’ve uninstalled Teams several times, made sure everything is updated. I can’t get it to work.

Please refer following suggestions:

Run Hardware and Devices troubleshooter from Settings app > Update & security > Troubleshoot.

If that doesn’t helps, try to re-register Camera app:

1. Press Windows +X and select Windows PowerShell (Admin).
2. Type/paste following and press Enter key:

3. Close Windows PowerShell and see if this resolves the issue.

Otherwise, try these steps:

1. Press Windows + X, select Device Manager.
2. Under Imaging devices, right click on your camera device and select Uninstall. Click OK.
3. Then click Action > Scan for hardware changes.
4. Close Device Manager and reboot.
