Yeah I think there's lots of room for improvement. I am told by others that I'm worlds clearer on the S3 than I was on the iPhone 4, fwiw.
I really look forward to the day of VoLTE, as I've not really ever been impressed with voice on any of the smartphones I've used...
I have a Nokia Lumia 810 with T-Mobile and the S3 on Sprint and the Lumia is hands down the winner on voice quality but the S3 is better at everything else so I'm not sure which one is better I am eagerly awaiting VoLTE as well. --
