By looking at this angle of development presents the depth Facebook obtains to guarantee better experience of what is the agent of mainstream hardware in the eco-system of Android on international basis.

Facebook made a viedo where they show the variables that proved it applied this practice of examining Android's hardware. It is an hour long video, but the first 13 minutes give a comprehensive perspective of the Android landscape for Facebook
