So my Nexus Galaxy Volume down button doesnt work. I have isolated it to the motherboard connection, its "disconnected" on one point of the motherboard where the volume up and down connections are. I would rather fix it myself than to send it off to Samsung and have them tinker with it for a month. Is the connection on the motherboard a soldered connection? Heres a photo to help see what Im talking about (http://guide-images.ifixit.net/igi/noJObJXR2ZSfniZV.large) Its the top part of the picture with the orangeish flap with the 3 connection points. The topmost point isnt connected like the other 2. Thanks for any help provided, Regards!
