I'm getting rid of my Blackberry and am interested in the RAZR, Galaxy Nexus, and maybe the 4S. My son has the GNex and it's very impressive, but the voice quality was a step down from Blackberry. It didn't sound on the listening end as good as my BB, and it didn't transmit as clean a voice signal to the recipient as my BB does. How's the sound quality on the RAZR compare to other phones? I use the phone for work and a quality voice call is important and a decent speakerphone is useful too. Next most important is full sync with Exchange server and a good searchable e-mail. I probably will not root the phone, so solutions that make the sound better but involve rooting aren't a good option.
