Tips for improving call quality

Because video calls use more bandwidth than voice calls, if you have problems with video call quality, try the following:

  • Quit other applications that use the Internet, especially those that play music and videos.
  • Cancel an ongoing file transfer.


If the problem persists

You may need to increase bandwidth.
