I am having an issue with my S6. Anytime audio is played there is a loud crackling noise. It only does it if the screen is on. If I turn off the screen with music streaming, it is fine. When I am in calls on speakerphone, it is fine. But when I watch a music video or listen to music while browsing, it crackles. I figure it can't be that the speaker is blown out since speakerphone and audio is fine with the screen off. No drops or spills. Been like this since day one. Any recommendations?
