iPhone 6 and the two-tone flash
Upon seeing numerous renditions of the iPhone 6, people are quick to dismiss it saying that it lacks a two-tone flash that the iPhone 5s brought.
But just what if Apple figured out a way to make that single flash unit burst two colours at once and have the camera software merge the two tones together? That would save some space for the flash unit.
On a design point of view, two circles also look more coherent than a circle with a pill-shaped flash.
