Apple is expected to release three new iPhone models in 2017, including an iPhone 7S with aluminum casing and an iPhone 8 with a glass casing reinforced with a stainless steel frame, DigiTimes reported Tuesday.

The iPhone 7S, which is expected to measure 4.7 inches, will continue using an aluminum-alloy chassis supplied by Catcher Technology, sources from the “upstream supply chain” told DigiTimes . The highly-anticipated 5.8-inch iPhone 8 will come with glass casing reinforced by a stainless steel frame supplied by Foxconn Technology and Jabil Circuit. Apple is also expected to release a 5.5-inch iPhone. That device’s casing has not been confirmed yet.

iPhone 8 (iPhone X) Feature Rumors

The iPhone 8 is rumored to come with an OLED panel which could stretch across the entire front of the device, meaning the iPhone might be price at more than $1,000.  

Apple might also ditch the physical home button from the new device by placing it underneath the display surface and will be a button to touch not press. The new iPhone could also come without physical buttons on the side of the device and instead have touch-sensitive inlays in the metal, according to a recent Fast Company report.

Other rumored features include face recognition, improved 3D Touch, and dual lens cameras on the 5.5-inch and 5.8-inch models.

Meanwhile, the smaller version of the iPhone 8, which could be called the iPhone 7S, could pack as much battery capacity as the iPhone 7 Plus, KGI Securities analyst Ming-Chi Kuo recently said.

Expect the iPhone 8 (iPhone X) and iPhone 7S release date to be this September.
