My Question or Issue

 Everytime I put my phone inside my pocket (or cover the front sensors) - when the phone enters "Pocket Mode", the sound is cutting out a couple of times, then continues to play normally. It happenes EVERY time, regardless of mobile data connectivity or speed, or which song is playing. Any help?
