iPhone SE features a 4-inch Retina display, an A9 chip with 64-bit desktop-class architecture, the Touch ID fingerprint sensor, a 12MP iSight camera, a FaceTime HD camera with Retina Flash, Live Photos, LTE and fast Wi-Fi, iOS 10, and iCloud.
I love the size of this phone. I don't need a huge phone to carry around, especially when I am outdoors most of the time. This fits nicely in my pocket and does everything I need it to do. Also I don't keep a lot of photos on my phone so the 16G is exactly the right size. Great phone!
