Bloomberg reports claimed Apple is testing iPhone prototypes which has a
“simpler design” with an aluminum back, rather than a glass one, plus
slightly larger dimensions.

Apple suppliers have so far struggled to
reliably produce heavily curved glass in mass quantities, so the company is
more likely to ship the version with more subdued curves, the person added. The
company is also testing a simpler design that has an aluminum back, rather
than a glass one, and slightly larger dimensions, one of the people said.

Beside that the sides of the iPhone include the same as in the current iPhone 7
Plus like mute switch, SIM card tray, Lightning connector, speakers.
