A secondary camera, often referred to as the front-facing camera, is typically located on the front side of a mobile device and is primarily used for selfies, video calls, and facial recognition. Unlike the primary (rear) camera, which usually offers higher resolution and advanced features for photography and video recording, the secondary camera focuses on user-facing interactions and convenience. Modern smartphones may include multiple front cameras for wide-angle shots, depth sensing, or enhanced portrait modes. As mobile communication and social media have evolved, the quality and capabilities of secondary cameras have significantly improved.
