One of the most recognizable features of Motorola’s Moto X line was the dimple on the back with their logo. Many other phones in their portfolio had the same cosmetic quirk, but none of them offered any functionality. It always seemed like a logical (and even intended) place for a fingerprint sensor. Well, a leaked image of the upcoming Motorola E5 shows that they’ve finally brought that concept to fruition. I guess better late than never.
