Got the update last Thu. Didn't see any problems but wouldn't have known since I spent most of Friday in no signal office and then parked phone for the night without even looking at it. Saturday morning running around and I get back to the wife and she's raising cain about me not answering my phone to come get her. What answer, I say? I didn't hear anything and I look and lo and behold....lots of missed calls. Uh-oh, the silent bug I say and she says WTF are you talking about? Nevermind....so I say, that's odd...worked fine last time I checked....call me. Never rings. Hmmm, let me call you. Her's rings...conversation goes on and I press SPEAKER....no speaker. My turn to say WTF. madly check settings...remove apps that mess with sound....put in earphone and play music...no problem...pull earphone...no sound. Uh-oh....worse than silent bug.
Off to VZW....baffled techs...hm, hard reset ought to do it. Great, all my free apps go away. Well, look they say, it's gonna be that way if we have to get you a new one anyway. OK. No help...further diagnostics...BAD SPEAKER!!!!! chip or what, I don't know. So here's a replacement but oh, we can't activate it cuz OUR SYSTEM IS DOWN in Little Rock!!!!!!
Finally that night it gets activated....and guess what....then I get an update notification!!! Amazing...I would have thought the phone they gave me would have been "current." So far, no problems.....again but we shall see.
So, check you AUDIO....it may not just be a silent bug.
