GoKawiilExplainer: How smartphone proximity sensors quietly power everyday features
A tech explainer details how modern smartphones rely on multiple proximity sensors to handle tasks like dimming the screen during calls, detecting when a phone is in a pocket, and supporting other automated behaviors. The piece traces how sensor-heavy design became standard after the original 2007 iPhone, noting that manufacturers have since competed to add more sensors, including some novelties like external temperature readers once found on certain Google Pixel phones.
