I had constant tiny clicking on all phone calls so I did everything I could to solve the issue (1 1/2 hours with verizon support) and finally wiped the machine to see if it would fix it... no luck. It was clearly a hardware issue with the speaker.
When I went in to exchange it they gave me a hard time - no one could hear the clicking (my wife could) but after some insistance they exchanged it.... no clicking now.
Actually i also am finding that my touches are getting the screen to respond better - the older one took a very precise touch to get something to work. This one is far better.
I bought a Verizon Network Extender to get better reception but it can't even get out of the house to find a tower... so it's going back tomorrow.
The only thing about the new phone that seems off is the magnifier key is brighter than the rest but if that's the only problem I can live with it
.
So far so good. If you have the clicking problem IT IS REAL. It's very soft but consistant when on a call.
