Samsung BEATb and Samsung BEATs come with ‘Motion Play' feature, which enables users to control their music with just few simple motions. For instance, users can play or pause music simply by tapping their phone. By flipping the phone, the music is muted and the phone is automatically set at the etiquette mode. Moreover, by simple shaking the phone, users can play the next song or previous song.Thankfully for Samsung fans, and knowing that people won't use this feature except to show off with their friends and to play for the first three days, they also include physical buttons. Do you think motion control is useful or even usable for full music control?
