My phone shuts off when I connect an auxiliary device! Please help! (Galaxy S6 Edge)

AC Question

I have a Galaxy S6 Edge that was in for screen repairs recently, and now I have two problems (of which I definitely cannot live with one). 1. My home button doesn't go as deep as it used to when clicked, it's very very shallow. 2. My phone shuts off when I try to connect an auxiliary source like my cars audio or even my earphones (this is the one I most definitely cannot live with). This was never a problem before, but since my life depends on music, this must be fixed.

Any quick fixes?
