Cameras are an important part of any smartphone, with many people preferring them to compact cameras. From the specifications, Samsung hasn't let us down with the Galaxy S4 camera, with a 13-megapixel rear camera, complete with Flash and a high-speed shutter mode. At the front is a 2-megapixel camera.
The 13-megapixel rear camera certainly has impressive specifications, but the front camera can be used to control the phone
Now, two cameras on a smartphone is hardly something new, but with Dual Camera you can operate both of them at the same time. It feels a little gimmicky to us, but the idea is that you can film yourself with the front camera and then superimpose yourself on the footage from the rear camera. The examples we've seen look a little twee and we're not sure that most people want their faces to appear surrounded by a postage stamp border over the footage they're recording.
You can superimpose yourself as a floating stamp in videos, if you like that kind of thing
The front camera also serves a purpose in controlling the phone with Smart Pause. This technology knows when you're looking at the screen so it can, for example, pause a video when you turn your head and look away. As soon as you look back, the video continues. It's a neat way of using the cameras for more than just still images and video.
