Hey everybody So.. My iPhone is 2 years old. Today I turned my iPhone on.. Everything worked fine.. But suddenly it turned off.. So i rebooted - and it worked.. I got a call, but I couldn't hear my speaking partner. So I looked if sound is working - but it doesn't even with earphones. But it seems not to be a sound problem only.. When I want to listen to music(so i click the play button".. Nothing happens, It just shows me the pause button.. Even youtube videos aren't working anymore.. Anyone an idea?
