The issue focused on digital cameras with sensors smaller than 16 megapixels and smartphones with processors faster than 2 GHz. While phones made before 2009 used electronic shutter technologies that electronically regulate exposure times to preserve sharp images, iPhones now rely on algorithms that compute exposures based on sensor pixels and computation speeds as fast as computers can execute calculations. As a result, phones lose resolution over time when sensors begin to degrade or electronics wear out. In addition, devices designed for tablets often ship with hardware sensors larger than 16 megapixels but
