My iphone 7 plus that i only got in september fell while i had m earphones in and so i noticed that my headphones still worked when in another phone and my laptop but when plugged into my phone after the fall, the music would play aloud as if nothing was plugged into the phone. i didn't think about it until i got home and tried to charge my phone but it wouldnt charge. I used a different wire, different outlet, even tried charging it from my laptop and nothing. i turned my phone off and plugged it in and it came on as if the charger was being detected like normal but when the phone turned on, it wasn't charging at all. the hole is free of debris and there's no visible sign of corrosion or any misshapen places. i think i have a warranty still but before i do that, is there anything i can do?
