Some ways the Samsung Galaxy S7 is better than the iPhone – update

Camera

You’ve probably heard that that the quality of the image a camera produces isn’t simply a matter of pixels, & the camera in the S7 looks set to prove it. The S7 has a 12 megapixel camera, down from 16 in the S6. Samsung claim the new camera will produce superior images, particularly in low light. This may be a hard idea to sell, but there are good reasons to believe it can work.

Cameras in top-of-the-range phones are remarkably good, despite the compromises required to cram them into the tiny space available in a phone which has skinny-jeans-compatibility as a major design parameter. A small space for the camera means a small space for the light-sensitive sensor. A high pixel count means that each individual pixel is smaller. The resulting minuscule light-sensitive pixels perform poorly, particularly in low-light, where they produce dark, low-contrast, “noisy” images.

A small sensor can most obviously be improved by making it bigger. While constrained by skinny-jeans-compatibility, Samsung has increased the size of the camera’s photo-sensor marginally from 1/2.6 inch (in the S6) to 1/2.5 inch in the S7. When combined with a reduced pixel-count, the S7 has significantly larger pixels. Rumour has it, 1.4 micron pixels, in the Galaxy S7, 1.12 micron in the S6.

Update: 1.4 micron pixels confirmed – camera teardown at: http://www.chipworks.com/about-chipworks/overview/blog/samsung-galaxy-s7-edge-teardown

Samsung claims that, in practice the new, larger pixels, are able to gather 56 percent more light than before, for better low-light images.

More obviously, images can be improved by letting more light into the camera, & Samsung have added an f1.7 lens.

A lens which lets in more light is sometimes said to be “fast”. This is a reference to the fact that with more light, the exposure time can be shorter, which leaves less time for camera shake or movement by the subject to reduce the quality of the image. Tim Cook could have recently used such a feature to avoid embarrassment at the Super Bowl.

We’ll have to wait for sample images, but taken together, these changes should yield better images, particularly in low light.

Fast charging

0-60% battery charge in 30 minutes.

microSD card

Returns in the S7 after being omitted from the S6, although Samsung hasn’t taken advantage of the latest Adoptable microSD capability in Android Marshmallow.

Waterproof

IP68 standard – one meter under water for 30 minutes. Also in the S5, omitted from the S6.
