Since the last update, my phone will NOT read out messages like it use to. It also will not show whose calling unless I unlock the screen when the phone is ringing.
Let's get to the bottom of this! Could you please confirm the software version your phone is on http://vz.to/1tryr3F ? Also, have you checked to see if the option is still turned on? Settings>Accessibility>Talkback

Most likely this is caused by a proximity sensor issue after that last update. Replacement is about the only recourse. I'd exchange under warranty by contacting VZW via phone or web chat. The store cannot help you as they don't have replacement units.
