Apple is testing at least ten different iPhone prototypes and Bloomberg said yesterday that one of the designs being considered features an aluminum back rather than a glass one, and slightly larger dimensions. Today, Australian leakster Sonny Dickson tweeted out an image of what appears to be a technical drawing for an aluminum iPhone 8 prototype (could it instead be an iPhone 7s prototype?) that shows vertically aligned dual cameras and a fingerprint sensor on the backside.
