My wife had the first Galaxy S (the Verizon version). We had to replace it after six months because it routinely would not accept incoming phone calls despite showing full reception, was extremely crash prone, and had awful call quality. We worked with Verizon to address the call quality/missed call issue, but it never helped.

A few weeks ago, my wife dropped it, and shattered the screen. The phone is still usable, but we took this as an excuse to get her an iPhone 4.

It is amazing how little anything matters when a phone doesn't function as a phone.
