Permission allowed, but still no video or sound?
Check system access
Your operating system must also allow the browser to use the camera and microphone.
Check the input
Select your intended webcam or microphone. Check the headset’s mute switch.
Close competing calls
Close other camera or recording applications, then reload the chat. Menu labels vary by device and version.
Distinguish a slow call from a failed launch
For repeated freezes with a working preview, stop competing downloads and try a stable connection. For an application that does not open, use the chat’s retry option. Give support the exact error and device if it continues.
FAQ
Will buying minutes fix my camera?
No. A purchase does not repair permissions or hardware.
Why can I hear someone but they cannot hear me?
Output and input are separate. Check your microphone selection, mute switch and browser permission.
