1.Calendar will not highlight the proper day 90% of the time only when I shut it off and turn it back on does it work right. 2.When I call other people they can barely understand me, they say I cut out and echo a lot. I sometimes here the echo too. Calls are placed to Verizon, Sprint and hard lines. I have turned the volume down, and to top it I'm on the 4th phone. Even when I call verizon tech support they here the same thing. What gives?
