Gigabyte GSmart Sierra S1 Review

GIGABYTE GSmart Sierra S1 6

Posted: , by




The phone features a 13 MP camera with LED flash on the back, and the camera interface offers a few basic shooting modes like HDR and Panorama, as well as a couple of color effects you can apply. Gigabyte sets the Sierra S1 apart by providing a dedicated camera button, so you don't have to rely only on the virtual shutter key.

Photos appear detailed enough for the resolution, though fine detail like tree branches and shrubbery show as a colorful mess on several photos. Noise is also a problem, easily visible even in rather good lighting conditions, which is not the case with other 13 MP handsets out there. Despite the apparent lack of noise-suppression, overall the images appear too soft, especially towards the edges. The color representation is natural, but there often is a pinkish hue cast over the frame. Scene exposure is a mixed bag, too, with the Sierra S1 often under- or overexposing the images, making them appear too dark or overly bright than what's in reality in front of the camera lens.

Indoors the phone showed passable performance, although the photos are definitely on the noisy side. The Sierra S1 may set the ISO as high as 2000+, which results in very grainy images usable only in small size. The LED flash is rather weak, failing to properly illuminate the scene from about a five feet distance.

Video is captured with 720p resolution and fluid 30fps, flaunting a decent video sound recording quality. It's fairly soft, too, though the detail situation is decent.


The stock Android gallery offers a grid thumbnail view of your photos and you get a few editing and color effect options built into the app. Google Play Music is used for your tunes, which allows you to set a couple of equalizer presets to suit the genre. The loudspeaker is of average quality, with decent strength, but somewhat flat sound. Video playback runs MKV, DivX and Xvid file formats without a hitch up to 1080p of resolution, though besides a loop function you can't find much other options in the default video player.
