It sounds like a loose speaker connection to me. It happened to my old Samsung Galaxy S 1. Try playing music off it on loud speaker, and if it cuts in and out, I am fairly certain it's your loudspeaker that is loose. Text may come in, but it is a shorter duration vibration for the speaker, so there is a higher chance the speaker won't cut out before the tone ends. If it turns out to be the loose speaker, a simple fix at your local repair shop should do the trick. Just unscrew and resolder.... You could try it yourself, of course, via Youtube or Google.View original
