The iPhone SE has a 4" (diagonal) widescreen multi-touch IPS LED-backlit 1136x640 native resolution (326 PPI) "retina display" without 3D Touch support, dual cameras -- a rear 12 megapixel, 4K "iSight" camera with 1.22-micron pixels, an f/2.2 aperture, a dual-LED "True Tone" flash and more as well as a much more modest front 1.2 megapixel, 720p "FaceTime" camera.

All iPhone SE models are powered by a 1.8 GHz 64-bit "Apple A9" processor and have 2 GB of LPDDR4 RAM. They also support 4G/LTE, 802.11ac Wi-Fi, Bluetooth 4.2, and NFC (for Apple Pay), have a bottom-mounted headphone jack, and use the "Lightning" connector to hook up with a Mac, PC, dock, or power adapter. Each also includes a first-generation "Touch ID" fingerprint sensor embedded in the "home" button.
