Display
The iPhone 8 and 8 Plus retain the Retina HD Display found in the I phone 7 but they now feature True Tone technology, allowing for automatic screen adjustments based on surrounding ambient lighting. They can play HDR10 and Dolby vision content despite not having an HDR-ready display, done by down-converting the HDR content to fit the display while still having some enhancements to dynamic range, contrast, and wide color gamut compared to standard content.

Reception
Samuel Axon of ARS TECHNICA called the A11 processor "a marvelous feat of engineering", writing that it offers "industry-leading performance". Axon also praised the cameras, writing that "The colors are great, and low light performance is very good for a smartphone". Chris Velazco of ENGADGET praised the speed of the A11 processor, the build quality and the "excellent" camera, while criticizing design familiarities with previous iPhone generations and limited water-protection levels compared to competitors.
John McCann of TECH RADAR enjoyed the feel of the glass back despite criticizing the phone's overall design. McCann also praised the camera and called inductive charging a "useful" addition to the iPhone lineup.
David Pierce of wired similarly stated that the iPhone 8 models were overshadowed by the iPhone X, despite calling them "virtually perfect phones". Pierce praised performance, cameras, and displays, while repeatedly criticizing the "outdated" design.
Nilay Patel of THE VERGE called the iPhone 8 the "default option", noting that the 8 models stand as almost universally overlooked by Apple's other new iPhone launched, the iPhone X. He nevertheless praised the device's form factor for being easy and non-slippery to hold, the display's addition of True Tone technology and upgraded speakers, though he cited issues with inductive charging speed through wireless pads as well as the price of the iPhone 8 Plus 256 GB, which was close to that of the iPhone X. Patel also criticized the iPhone 8's aging design, dating back to the iPhone 6 released in 2014; the most notable critique was of the thick bezels when compared to other 2017 smartphones, designed with nearly bezel-less faces to incorporate larger screens in a similar form factor.
The iPhone 8 and 8 Plus were also criticized for their durability, as drop tests performed showed that the rear glass is not "the most durable glass ever in a smartphone", as claimed by Apple.
Camera testing company DXO MARK gave the camera on the iPhone 8 a rating of 92 and 8 Plus a rating of 94, giving them the title of best smartphone cameras tested by the company. The samsung galaxy note 8 later matched the iPhone 8 Plus with an identical overall score of 94. They were later overtaken by the Google pixel 2, which scored a 98 rating.
Although being the first mobile phone to record 2160p at 60 frames per second, the iPhone 8, 8 Plus and X have been criticized in a review by GSMArena for its mono (single-channel) audio recording for videos, while streo audio recording for videos has been available on competing mobile phone models for several years, such as the samsung galaxy s3 and sony xperia s from 2012.
