I dont really know anything at all about all this android stuff, but I took the warrenty off my phone and now my headphone jack is acting up. When I plug in headphones you can hear like.. acoustics really good I guess? But all the singing ecos and I can barely hear it.. But then I plug it into the aux port in my car and it plays music perfectly fine. Its not the headphones because It was happening with my old ones so I went out and bought brand new ones and it does the same thing. Plus I use these headphones with my computer so I know they work. Any way this is fixable?:/ Could I pop the phone open and replace the aux jack easly?
