Hi everyone. I have problem with jack when I listen music it disconnect itself. First I thought that jack is dirty so I cleaned it. Then it works better but I found where is problem. If I push on the back side music pause. You can see it in video: https://www.youtube.com/watch?v=MWkj3lWtwHc . Do you think they repair it in service? OR Can somebody try it on your Z5 premium ?
