LG G6 Mobile review: Punchy pictures

DxOMark Mobile

The LG G6 features a dual-camera setup with two 13Mp sensors coupled to either an f/1.8 image-stabilized lens for its primary camera, or to a second f/2.4 wide-angle lens, without autofocus, as an alternative option. Tested using the primary camera, the LG G6 achieves an overall DxOMark Mobile score of 84 points and performs better for stills, securing a Photo sub-score of 85 points.

Its achieves its best scores for stills are in bright light, in which exposures are generally excellent, with good white balance, vivid color, high levels of detail, and fast autofocus. A noticeable increase in correlated noise, as well as less detail in low-contrast areas, results in the LG G6 ranking just behind its predecessor, the LG V20, which achieved a Photo sub-score of 86 points.

For video, the LG G6’s 2160p/30fps module achieves a Video sub-score of 83 points, which is 1 point better than the LG V20, thanks in part to the former’s improved stabilization system. Again, videos are better in bright light, with the main strengths accurate exposure with wide dynamic range, good detail preservation, pleasant white balance, and well-controlled color shading.


The LG G6’s primary camera set up, featuring a 13Mp sensor and a f/1.8 OIS lens, is capable of excellent and vibrant exposures, with bold color and high levels of detail in textured areas


Outdoors: Nice exposures with vibrant color

Shooting in good outdoor lighting conditions, the LG G6 produces many vibrant and accurate exposures that pack plenty of punch. Accurate target exposures boast vivid color rendition and generally accurate white balance. In some exposures, however, white balance can veer towards a slight blue/greenish tint, and although it’s not overly offensive, some post-production correction to warm things up could help.

HDR exposures shooting towards the light in high-contrast scenes are also a little inconsistent, often rendering overexposed highlights or clipped shadows. Watch out for haloing around contrast edges on HDR exposures, too. The 13Mp sensors records good detail, particularly in textured or high contrast areas, although fine detail is often lost in low-contrast areas. The LG G6’s autofocus is excellent in bright light, locking on to subjects quickly and accurately.

Shooting towards the light in high-contrast scenes, dynamic range can be more limited in some exposures, with either clipped shadows (top) or blown highlights (bottom).


Indoor: Inconsistent results

The LG G6’s low light results can be a little inconsistent in terms of exposure, detail and noise. Under brighter 300/100 Lux artificial lighting, indoor photos do pack a similar punch to its outdoor shots, with good exposure, vibrant color and a nice, albeit slightly greenish, white balance.

This level of brightness is not repeatable over consecutive shots using the same settings, however, with the next frame recording a duller exposure. In darker 10/5 Lux exposures, brightness is more consistent, and although a little underexposed with subdued color, overall very low-light shots remain usable.

Some visible color shading that shifts from pink in the center to green at the edges is also visible in low-light pictures. More concerning, however, is heavy correlated luminance noise in low-light shots, which results in a loss of detail and a textured oil painting effect in some areas. The effect can be quite distracting, but it’s also inconsistent: some pictures display high levels of correlated noise, while some consecutive shots using the same settings offering smoother results, with lower noise and less fine detail.

Details: Explaining the score


Details: Explaining the score

Exposure and Contrast (88)

The LG G6 achieves its highest category score for Exposure and Contrast, thanks to the generally accurate target exposures and punchy, vibrant results. It lost points for certain exposure variations, specifically in low light, and for HDR irregularities that displayed some limited dynamic range.

Exposure and Contrast (88)

Successful HDR exposures display great dynamic range, preserving detail in the shadows and highlights, but some noticeable haloing along high-contrast edges (for example, the trees), is evident


Color (84)

The LG G6 scores well for color, which is especially vibrant and bold on well-exposed outdoor pictures. Color is good in low light, too, aside from underexposed shots, which are a little drab. White balance is generally accurate, although both outdoor and indoor pictures have a slight blue/greenish cast, which might not appeal to photographers who prefer warmer results.

Color (84)

Shooting outdoors, white balance is generally accurate, and although a minor blue/greenish colorcast is slightly visible, it doesn’t detract from the good color of the LG G6’s photos


Autofocus (85)

The LG G6 achieves a great score for autofocus, thanks to the fast and accurate performance of its phase detection system. It’s especially fast in bright light, and although not bad in low light, we observed more failures, notably in trigger mode.

Texture (87) and Noise (82)

The LG G6 achieves a good score for texture that is particularly impressive in bright light, with the only complaint a loss of fine detail in low-contrast areas. In low light, more fine detail is lost and many textures have a somewhat distracting oil painting rendering. A lower score for noise was achieved, with heavy correlated noise evident both in indoor pictures and in some areas of outdoor pictures, too. As already discussed, the inconsistent levels of noise across consecutive exposures is a concern, too, with high levels of noise in some pictures seriously affecting image quality.

We found the level of noise to be very inconsistent across consecutive pictures shot in low light both in the lab and on location, with some pictures noticeably more affected


Artifacts (80)

A number of artifacts are evident in the LG G6’s pictures, the most problematic being the inconsistent denoising across darker and brighter areas of the same picture, haloing around buildings or contrast edges, and noticeable flare in pictures shot towards the light.

Of less concern, edge detail is often noticeably noisy, maze/moiré patterns are sometimes visible on high frequency areas, and a cyan shift in the sky is occasionally apparent.

Flash (88)

The LG G6’s dual LED module achieves a great score here due to its stable exposure and white balance on flash pictures, especially when using additional light sources. On flash-only results, colors are pleasant and detail preservation is good, but pictures are slightly underexposed, with noticeable light attenuation in the corners. Strong color shading is visible when mixing flash with additional tungsten light sources.


Video (83)

Video (83)

On the whole, the LG G6 shoots many successful videos with accurate target exposures, wide dynamic range, and smooth exposure adaptation when changing scenes. Colors are bold and vivid in bright light, with accurate white balance, both outdoors and when shooting under fluorescent lighting.

In low light, colors are a little under-saturated, with a minor pink colorcast under indoor tungsten light sources. Changes to the color matrix are noticeable when transitioning between bright- and low-light conditions, with visible steps in white balance adaptation evident.

The LG G6 video stabilization system is pretty effective in bright and low light, with only slightly visible high-frequency motion in some videos, and some judder effect with panning movements.

Detail preservation is good in bright light, too, with well-controlled noise reduction for smooth results, although some luminance noise is more visible on specific colors.

However, detail preservation is fairly low in low light, with more visible luminance and chromatic noise evident. Autofocus is mostly accurate, especially in bright light, although occasional loss of focus during walking and tracking movements is evident. Again, results are better in bright light, as autofocus is fairly slow in low light, with visible steps in convergence and some unpredictability, including refocusing during lighting changes. Artifacts are occasionally noticeable on the LG G6’s video, too, including ringing and flare; and the same instability with low light noise that we saw with stills persists in low-light videos, especially during lighting changes.

    You will retest G6 to give the score with the new protocol?

  • Mikawelll

    Copy/paste error at the bottom of the article? “Videos Cons” and “Videos Pros” are the same.

    • Алексей Неважно

      The author overworked )))

  • Jadson Correia

    Esse teste é uma piada, o LG G6 tem a melhor câmera de 2017 com certeza

  • Omar Abbas

    The question is: Why the score isn’t at the home page with other top scores !!!!

  • NecaNew

    Retest G6 with new protocol and post new results.This shouldn’t even be a thing to ask,you should have done like you did it for rest of the phones.

  • petoro

    As Mikawelll points, the video Cons coincide with the video Pros. Perhaps it could be fixed.

    • flodxomark

      Hello. We notified this problem and we’ll fix it as soon as possible. Thanks.

      • petoro

        Thank you.

  • Sachin Somra

    Plzz Retest LG G6

  • Gleb

    Please retest!

  • Filip

    All the phones are being retested with the new protocol except for the LG G6. Seems like Dxomark is supporting the marketing campaign of Google and Samsung. As Omar Abbas says, this phone its not even listed in the top scored at the home page.

    • ginlucks

      Why instead of try to change their mentality you don’t try to change site? Dx clearly follows the money shamelessly. Do you will trust them again if they will retest the g6 after a so long period?

  • DanielDC1984

    Please, retest this phone. Thanks in advance.

    P.S. And include mentions to the wide angle camera, please.

  • Guys! Need to retest the G6!

  • michael238

    I would love to see how the G6 stacks up with the new testing methodology. Please retest

  • Martin

    my G6 is from VODAFONE CZ distribution. Wide angle camera have 2.09mm focal lenght and picture quality is terrible.

  • richard

    use 4:3(13mp) aspect ratio,for more accurate exposure

  • Pierre


    Vous serait-il possible de re Tester avec ne nouveau protocole le LG G6 s’il vous plait, et c’est pour quand une version française de ce site ? c’est une bonne idée hein ? 🙂 – Sinon j’ai remarqué que LG G6 est un très bon photophone, je l’ai comparé à un APN dédié mais, les résultats sont bluffants, certes je n’ai pas utilisé le zoom mais le LG se débrouille très bien

    D’avance merci

    bien à vous

We are hiring!
