I purchased one Samsung Fascinate from a Best Buy in October and returned it for various reasons and I repurchased another one yesterday from a different Best Buy. When I made or answered a phone call on the first SF, a small sound or tone would play upon ending the phone call. However, with this second SF, I do not have a tone playing when ending a phone call or hanging up. Was the first phone made differently or is my second phone missing something. Does anybody else's Samsung Fascinate play a tone when they hand up from a call?
