This page will be dedicated to a general overview of descriptions and information related to the ADT-1 Android TV.

Purchase

The ADT-1 is not available for purchase and is only obtained through purchase from individuals who obtained a unit at Google IO or through the official "Request an ADT-1" page.

Tear Down

The ADT-1 Android TV is pretty easy to get apart once all the clips holding the case together are undone. In this tear down we used a razor blade but a guitar pick or similar small and durable piece of plastic is recommended.
