I have issues with the speaker, there are annoying distortions while playing mp3 on Walkman player or any other player. I tried updating to ICS but the problem still exists. The problem occurs with earphones also. Distortions are not present during calls and videos. In fact, videos play flawlessly.I tried playing my music on several other mp3 players and there are still distortions present from which I can only deduce that something is wrong with the speaker. Also coincidentally my friend's SE LWW also has the same problem.
