iPhone 7 models have a 4.7" (diagonal) widescreen multitouch LED-backlit 1334x750 native resolution "Retina HD" display (326 ppi, 625 cd/m2) and a taptic-engine powered solid state "clickless" Home button. It has dual cameras -- a rear 12-megapixel camera with optical image stabilization, a f/1.8 aperture, a 6-element lens and wide color capture -- as well as a front 7-megapixel "FaceTime HD" camera with support for 1080p video.
The iPhone 7 is powered by a 64-bit "Apple A10 Fusion" processor with four cores -- two high performance cores and two high efficiency cores -- and has 2 GB of RAM, as well as 32 GB, 128 GB, or 256 GB of flash storage (jet black and red options originally were only available in 128 GB and 256 GB capacities, although Apple introduced a 32 GB jet black variant on September 12, 2017 when it also discontinued the 256 GB capacity for all colors). It also supports 802.11a/b/g/n/ac Wi-Fi with MIMO, Bluetooth 4.2, LTE (4G), and NFC for Apple Pay.
