This is a second generation feature that allows you to block all incoming calls while you are playing games. When this feature is turned on all incoming calls, including VoIP calls from IM apps, such as WeChat, QQ, Line, Messenger, WhatsApp, Viber, Skype, will be blocked in order to offer you a more immersive gaming experience without interruptions.
After you launch a game, swipe in from the left edge to call out Game Genie > tap No calls icon to turn it on/off.
