So I was trying to get my n4 into silent mode via pressing the volume button like I do every night and the n4 refused to go into silent/vibrate. When pressing the volume button, I can see the speaker icon with the slide scale of volume increase/ decrease but didn't go into silent/vibrate. I had to reboot the phone. I've been having strange things happen to my n4 after the update. Freezes/crashes, slow WiFi slow data, unresponsive touch screen, slow keyboard response time, bad reception anywhere. In fact, the only thing I have noticed an improvement on has been the battery. Anyways, has anybody noticed the volume thing? I've had to reboot my phone more in the last several days then I did the 8 or so months of owning this thing.
