Overview

Featuring a large 5.5-inch, high-resolution 1440 x 2560 pixel screen and running a powerful Snapdragon 808 chipset with quad-core 1.44Ghz and dual-core 1.82 Ghz Cortex processors, along with 3GB RAM, the G4 is certainly equipped for performance.

The primary camera is promising, too, offering a 16Mp (5312 x 2988 pixel) resolution on a 1/2.6in sensor, with the secondary camera still a respectable, albeit lower resolution, 8Mp snapper. Other notable camera features include laser autofocus, optical image stabilization, LED flash, simultaneous video and image recording, geo-tagging, face detection, and HDR processing. Shooting moving images, the G4 records at either 2160p/30fps or 1080p/60fps on the primary camera, and a lower-resolution 1080p/30fps on the secondary camera when Skyping and the like.

With so many DxOMark enthusiasts requesting an in-depth analysis of the G4’s image quality, we’re delighted to bring you a full round-up review of our latest mobile tests.
