I have an LG Quantum. I've noticed that there is a kind of crackle or pop each time a new track begins in my playlist. Has anyone else noticed this? It's faint, but with in-ear headphones, I can definitely make it out. I've also tried using a different pair and get the same result. Also, at least with the LG Quantum, I've noticed that I have to set my volume up to 26 in order to get the same volume as I would get from my old iPhone if I have the volume a little past halfway. Am I missing something? TIA.
