A 4.7-inch Retina HD display with 3D Touch. 7000 Series aluminum and stronger cover glass. An A9 chip with 64-bit desktop-class architecture. 12MP iSight camera with Live Photos. Touch ID. Faster LTE and Wi-Fi. Long battery life. And iOS 9 and iCloud. All in a smooth continuous unibody design.
Unfortunately, I returned the first phone I received due to a faulty battery. After a couple of weeks, I received the replacement. I will be returning that tomorrow due to a non-functioning rear camera. I will not be purchasing this item again. Certified? What's that mean anymore?
