The iPhone 7 has a 4.7-inch screen at 1334×750, also known by Apple as a Retina HD display. The iPhone has a front and back camera: the rear camera is 12-megapixel and the front camera is a 7-megapixel FaceTime HD camera with 1080p video.
The iPhone 7 was the first iPhone (along with the iPhone 7 Plus) to remove the 3.5 mm headphone jack and only include a Lightning port for audio. Like the iPhone 6 and 6s before it, the iPhone 7 uses a “clickless” Home button that clicks using an internal Taptic-engine-powered solid state component. Although the iPhone 7 is not water-proof, it is splash, water, and dust-resistant.
The iPhone 7 came in several colors: silver (white glass front, silver back); gold (white glass front, gold back); rose gold (white glass front, pink-tinted gold back); black (black glass front, matte black back); jet black (black glass front, a high-gloss black anodized and polished black aluminum back); and later added a (PRODUCT)RED Special Edition (white glass front, red aluminum back).
The iPhone 7 uses the Apple A10 Fusion processor, 2 GB of RAM, and was available with 32 GB, 128 GB, or 256 GB of flash storage.
While I opted for the iPhone 7 Plus as my personal phone in the iPhone 7 era, I chose the then-new (and not offered since) jet black color. I immediately covered the glossy finish with a case to heed Apple’s warning that jet black “may show fine micro-abrasions with use.” (It did scratch easily!)
