Like Q, Mendez has a collection of gadgets -- among them, a skin mole that carries a piece of espionage equipment called a bullet lens, and a coat on which one button is the lens to a concealed camera.
We discussed the extremely narrow display bezel, striking RGB notification ring around the home button, recessed camera lens and IR blaster (for the QRemote functionality).
The L-Fn (Lens Function) button suspends the autofocusing operation temporarily to avoid unintended focusing on obstacles that appear suddenly between the camera and the subject.
