Our online glossary is here to help you make sense of the terminology used in the cell phone industry. It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.

What is "Camera"?

Many handsets and other mobile devices (like tablets) come with cameras installed. These cameras allow the device to be operated as a digital camera and many devices have a primary lens on the rear of a device and a front facing lens on the screen side.

Once a rare feature that stood a mobile phone apart, cameras are now virtually standard on all smartphones and manufacturers compete to offer the best user experience. This competition has led to high end smartphones boasting cameras that can compete with standalone products worth hundreds of dollars. The quality of smartphone imaging has led to a collapse of traditional point and shoot digital camera sales, and smartphones are increasingly moving towards DSLR quality.

Auto focus, optical image stabilization, digital zoom, LED flash, and other features are now common on smartphones, while most mobile devices can shoot video on both the front and rear lens. Some flagships have the ability to capture video in 4K resolution.
