I have researched this problem for quite some time. When I plug my galaxy S5( I have had 2 and one Galaxy4) into the stereo auxiliary input jack in my car, I get a static bad grounding noise. If I use an Apple, my daughters 5 and 6, no issue at all. So, I got the 4 pole plug to ensure it goes into phone and is identical to factory Samsung headphones. No change. I have cleaned it, no change,. There seems to be a lot of "fixes", but I cant find an actual FIX. What is the problem with this phone, Samsung etc? Please advise.
