Samsung Galaxy S III

In 2017 the DxOMark Mobile test protocol has been updated to cover zoom, bokeh features, very low light performance, motion in the scene and other new test criteria. Image quality testing for this review was still undertaken using the original DxOMark Mobile test protocol from 2012. The results are not directly comparable to the new protocol but this article will still give you a very good idea of the test device's camera performance.

Some in the mobile industry are calling Samsung’s Galaxy S III a game changer. In many respects it is for camera users. The Galaxy S III, with its innovative photo-sharing technology and digital still camera-like features, is tailor-made for casual point-and-shoot photographers. While its image quality isn’t perfect, its improved camera performance over the Galaxy S II illustrates how mobile companies continue to sharpen their focus on enhancing image quality.

The S III’s 8-megapixel camera places it among the top tier of smartphone cameras. To date, its quick autofocus leads the industry in speed and accuracy. The device also reproduces rich colors, especially in outdoor conditions, for both still images and video. Its flash is also praise-worthy, helping users snap well and evenly exposed photographs in dim lighting. 
But the S III is not perfect, it is tripped up in low light where it loses details, its auto-exposure wobbles, and its colors can looked washed out. The mobile’s video also suffers from strong noise in low lighting. It is also susceptible to the jello effect and jumpy stabilization.
