Y’see, the One M8 Eye uses a 13 megapixel BSI camera, with an f/2.0 aperture lens instead of the “Ultrapixel” 4-megapixel camera (which resulted in images with larger 2-micron pixels) that the regular M8 uses. Both have a second camera to complete their “Duo Camera” system, and both have a dual-tone dual-LED flash. Apart from that, both phones are pretty much identical. Even the specs of the One M8 EYE are pretty much exactly the same as the Asian variant of the One M8. The only one design detail that’s different, is that the bands at the back dont have a line touching the rear camera.
