What is a dual camera? To put it simply, it is a smartphone that has two camera sensors that work in unison to create one image. Usually, the main camera captures the image, and then the second camera helps add complexity to the photo, usually in the form of the depth of field. How these two cameras work together and what features they produce depends heavily on the manufacturer of the phone and the software they have developed.
Screen aspect ratio is not the same as display size, though. Actual display size is calculated by measuring diagonally across the screen. Most smartphones these days range from a 5.5” to a 6” display. By adjusting the screen aspect ratio, smartphone producers are able to increase the total display area, without increasing the size of the phone to the point where using it is inconvenient.
Smartphone apps especially have changed our lives in numerous ways, and it stretches beyond just our Internet speeds. The Google Play store has more than 3 million apps for Android smartphones, and that number continues to grow, infiltrating both our personal and professional lives in many ways.
