DK2 has a built-in latency tester that allows developers to quickly and precisely measure the motion-to-photon latency of their apps and games.
Note that the The DK2's display is literally the [[Samsung Galaxy Note 3]]'s display. If you disassemble the product and remove the display from its casing, you'll even find Samsung's branding on the display. Oculus partnered with Samsung to do this.
