Recently my Wii U's gamepad pops whenever I touch it with my finger. It started when I waa sitting on the floor with the gamepad on both of my hands and I accidentaly let my right hand. It hit the floor with the right side. I was playing wind waker so I noticed it when I was moving items. It's driving me crazy!!! It'a got worse now it sounds louder and really bothers me. It works perfectly but I'm OCD with my console. Any ideas abojt what's this or any solutions besides sending it to Nintendo?
