How to undo silent mode on Nexus 4 On the Nexus 4, I can silence the ringer by pushing the volume down button, however, when I push the volume up button, the ringer remains on silence until I go to settings and change the volume bar in ringtones. Shouldnt the volume up button work? Any suggestions?
That's odd - mine behaves the way you want:  pressing volume down decreases the volume, and then goes into vibrate and finally silent mode; then pressing volume up reverses all of this.

My Nexus 4 has the current version of Android: 4.3 (JWR66Y) on it.
