The mute or silent option is used when a bell on the phone can create disturbance to the working like meeting and sittings. If the mute button of Samsung Galaxy S2 Duos is not working properly, there is no way to keep it silent other than throwing it into the wall. But before the situation reaches the mute button must be asked to be repaired or replaced.
