DPReview smartphone reviews are written with the needs of photographers in mind. We focus on camera features, performance, and image quality.

The LG G4 follows on last year's G3, and like its predecessor puts a lot of emphasis on camera specification. The 16MP 1/2.6-inch CMOS sensor is a touch larger than the 1/3-inch sensors in many other phones, and the F1.8 aperture is the fastest among the current crop of high-end mobile devices, even surpassing the Samsung Galaxy S6's F1.9 variant. The G4's improved optical image stabilization system works along 3 axis, compared to 2 axis on the G3, and comes with a range of stabilization that has been increased from 1 to 2 degrees.

As before, the contrast detect autofocus is supported by a laser system for increased speed and reliability. In addition, the G4 comes with a new color spectrum sensor that reads RGB color and Infrared in order to recognize objects in a scene and their color. This information is then used to optimize white balance and color processing. At the front an 8MP sensor is combined with an F2.0 aperture.

In the camera app a manual mode that allows for adjustment of shutter speed, ISO and white balance has been added and, thanks to Android 5.0, the G4 is capable of recording DNG Raw files which can be saved to 32GB of internal memory or a microSD card with a capacity of up to 128GB. On paper the LG G4 looks like any mobile photographer's dream machine. Read our full review to see how the impressive specification translates into image quality and camera performance.
