So my sister has a galaxy nexus and while she was having a bath she acctidentally dip it in water but only bottom part to the led light, she didn't tell anyone about it and pretended like nothing happend. Later when she tried charging it everything was fine but after 10min of charging it stopped charging. I tried using her wall adapter with my iphone and it works, so I tried pluging in her nexus in my lg smart tvs usb port and it showed up as media device but it wasn't charging(my iphone could charge frome that usb port) so finally I plugged it in to my wifi routers usb port and now it is charging but how can I make it charge with wall adapter again? Wall adapter is working because I can charge my iphone with it and everything is phone with the phone because wifi router can charge it, so where is the problem?
