Hi, 9 days ago I purchased an Epic 4G from a Sprint Store. Yesterday I came back to the store complaining of ECHOES from the receiving end only with the SPEAKERPHONE on. The Tech tested it and told me that all smartphones are like that except for Blackberries. I said "Is that a fact or a matter of opinion?" He said "that's a fact." Do anyone have anything to say about my issue? Thank you very much.
