another review of Galaxy W :
http://www.mobilityfeeds.com/mobility-feed...one-review.htmlHere's what they mentioned about the call quality:
"Call quality was very good in our tests.
The volume was loud, voices sounded strong, clear, and true, though a tiny bit hazy, and there wasn't any other regular background noise.
We did intermittently hear an odd high-frequency whine, though it wasn't disruptive enough to throw off the conversational flow.
It was more or less the same story on the caller's end as well, with strong volume and a clear background line, plus voice quality that was a tad muddy around the edges.
Speakerphone was very loud for both parties when we held the phone at waist level, a plus in this case since this regular test caller has noted that other phones slice volume in half.
Still, our voice sounded distant and echoey to our caller, who added that they didn't want to maintain a longer conversation over it if they didn't have to.
The echo was also apparent on our end, but less so, and the line remained clear, without background interruptions or blips."
