一键静音

一键切换手机的静音和正常铃声模式，可以通过打开App点击界面中唯一一个最大的按钮实现两种模式的切换。

当从静音模式恢复为正常铃声模式的，系统自动记录静音前的音量大小，与长按电源键弹出来选择手机铃声模式的功能类似，只是“一键静音”更为简单。

目前仅在Google Nexus 4上测试。 A key switch phones ringing mute and normal mode, you can switch between the two modes is achieved by opening the App click interface the only one of the largest button.

       When recovery from silent mode to normal ringing mode, the system automatically records the volume muted before, and press the power button to pop up to select the mode functions like ringtones, just "a mute button" easier.

        Currently tested only on the Google Nexus 4.
