What is the U62 pin for?
On the nexus, there is a connector that connects between the device internals and a form of copper sheet on the back cover. What is the purpose of this connector?
My best guess would be Antennae??
It may be used to act as a ground for the board. My iPhone has a connector to a sheet of metal on the back and my MacBook Pro has connectors to the aluminum bottom panel, both devices using them as grounds. This is my best guess.
