Having problems with poor quality, freezing, delay, or dropped calls? You, and the person you're calling should check the connection of the internet:

If your audio or video calls freeze, your video looks block-like or has motion blur, it might be your internet connection (or the person you're calling) causing the problem. If Karify detects a weak connection, it will reduce the quality to try and stop the call from dropping altogether. 

You need an internet connection of at least 500 kbps. Open Wifi-networks for example could cause problems with the quality of the call.
