According to the ex-CEO, who now works at Dropbox, the dimple on the back of the device was meant to house the sensor. “The secret behind that is that it was supposed to be fingerprint recognition, and Apple bought the best supplier.” Woodside said. “So the second best supplier was the only one available to everyone else in the industry and they weren’t there yet.”
The fingerprint reader came out with the iPhone 5, if I recall correctly. Does that mean the Nexus 6 was in concept then? So early? Woodside might say Nexus 6 here, though I believe he means the Moto X as well.
Honestly, fingerprint recognition is not very important to me. I live dangerously without any phone-screen authentication.
