The iPhone 8 uses an aluminum alloy case reinforced by steel and has a glass front and back. It is splash, water, and dust-resistant (IP67), but not water-proof, and it has stereo speakers and a Lightning port.
Phone 8 models have a 4.7 (diagonal) widescreen multitouch True Tone 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 4K 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 cameras support motion tracking and offer augmented reality support.
Internally, the iPhone 8 is powered by a 64-bit Apple A11 Bionic processor with six cores -- two performance cores and four high-efficiency cores -- and has 2 GB of RAM, Bluetooth 5.0, LTE (4G), and NFC for Apple Pay.
