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.

Issues

On August 31, 2018, Apple announced that a "very small percentage" of iPhone 8 devices released between September 2017 and March 2018 contained a manufacturing defect in the logic board. This fault affected iPhone 8 models sold in Australia, China, Hong Kong, India, Japan, Macau, New Zealand, and the United States. Defective devices may experience unexpected reboots, a frozen or unresponsive screen, or may fail to turn on. Users with an affected device, as determined by their serial number, can have their device replaced for free by Apple. This issue does not affect the iPhone 8 Plus.
