Building on the success of the Galaxy SIII, Samsung has further improved the camera on the Galaxy S4, with a higher megapixel count and even faster performance.
In fact, the S4 has the highest megapixel count of the smartphones on test here - at a whopping 13-megapixels, it is as powerful as some compact cameras.
Usability: Although not enabled out of the box, the camera shortcut can be turned on in the S4 settings, allowing you launch the camera directly from the lock screen, exactly like in the HTC One.
The volume buttons can be customised to snap a photo or to zoom when pressed in camera mode.
There are a few camera settings available to tweak, including ISO, metering mode, white balance, exposure compensation and an anti-shake feature.
Screen quality: One thing to note is that the S4's screen is very bright and contrasty, but displays images with brighter, more punchy colours than when viewed on our colour calibrated monitor.
This means that while the photos will look pretty good on the S4's screen, the display is not actually showing you what the image is really like.
This isn't a problem if you just view those photos on the S4, but you may get unexpected results if you want to print them without any adjustment.
Image quality: At 13-megapixels, the S4 is a serious contender when it comes to image quality. In bright light, the camera produces the best detail with surprisingly good dynamic range.
Our detail test consistently showed that the S4 is capable of producing the best images in very bright light.
Night shooting: The high megapixel count of the Galaxy S4, while brilliant in bright light, tended to work against the camera in low-light situations.
The camera's noise reduction is quite strong to combat noise in low light, resulting in images that were lacking in much detail when viewed closely.
Having said that, overall exposure was pretty good.
