The key lock the music keys, the outside are attached to the mobile phone switched off this half. Only the "play / stop" button in the center is reasonable disabled. The other two buttons (forward / back) react despite the keypad is locked when you press it a little pushy or just simply having the phone in your pocket. Since I have to ask what I mean by an MP3 player to the self-selects the music I listen to, and thus not even wait until the end of a song .... Anyway ... as long as this problem remains Sony Ericsson does not resolve the W380i is a phone with a great design, solid equipment and a completely worthless integrated MP3 players.
