These days, a fingerprint scanner on a smartphone is no big deal, and octa-core CPUs are seen on mid-range handsets. But back in early 2011, the Motorola Atrix 4G was one of the first smartphones to feature a dual-core processor.
The AT&T exclusive also featured a fingerprint scanner. Unlike today’s rear-facing scanners and the ones found embedded inside a home button, the Atrix 4G had its fingerprint scanner inside the power button. It was placed on an angle on the top of the back cover. It worked so poorly that it set back biometrics on smartphones for about two years. The fingerprint scanner was so disliked that Motorola left it off of the sequel.
