Samsung Galaxy J2 Pro (2018) review: Simple and Affordable

DxOMark Mobile

Like previous versions, the latest incarnation of the Samsung Galaxy J2 Pro is an entry-level smartphone that’s marketed at an accessible price point. It features a relatively large 5-in Super AMOLED display and is powered by a Qualcomm Snapdragon 425 quad-core chipset.

The rear camera naturally is similarly poised at the entry-level. Naturally, it eschews the double camera module and accompanying AI tech found in the company’s higher-end offerings for a much simpler set-up consisting of a single camera with a 8MP 1/3” type sensor and wide-angle lens. The latter is optically stabilized and has autofocus but at f/2.2 is slower (less bright) than the apertures on higher-end models.

Other specs are relatively basic but include a single LED for low-light shots, HDR and Panorama modes. No smartphone would be complete without video capture of course but footage is restricted to a useful, if conventional, 1080p at just 30fps.

Key camera specifications:

  • 8Mp 1/3-inch CMOS sensor
  • f/2.2 aperture lens
  • Optical Image Stabilization (OIS)
  • Phase detection autofocus (PDAF)
  • Single LED flash
  • 1080p up to 30 fps video
  • 5-in AMOLED display

About DxOMark Mobile tests: For scoring and analysis in our smartphone camera reviews, DxOMark engineers capture and evaluate over 1500 test images and more than 2 hours of video both in controlled lab environments and in natural indoor and outdoor scenes, using the camera’s default settings. This article is designed to highlight the most important results of our testing.

Test summary

The Galaxy J2 Pro delivers well-saturated images, albeit with a slightly lower target exposure, however, white balance is mostly accurate.

The Samsung Galaxy J2 Pro achieves an overall DxOMark score of 65 points, placing it towards the lower end of the scale in our labs, behind the Sony Xperia XA2 Ultra at 75 points and above Energizer’s ruggedized E520 at 49 points. In terms of capabilities between stills and video the Galaxy J2 Pro is a well balanced device, where it scored 64 and 65 points respectively.

For stills the rear camera performs quite strongly in terms of autofocus accuracy and has fairly low noise levels in all our test conditions. In fairness, the camera performs reasonably well but there are several opportunities for improvement. This includes texture rendition, which was lacking especially in low light shots. In low contrast areas of the image levels of detail are low, even when shooting in bright light. We would also like to see better control of flare which was strong in several of our test shots.

Images show a lack of low-contrast detail, even in bright light.
Crop – low contrast detail

We also detected a bug in the OIS firmware which was the cause of uneven sharpness across the plane of focus. Some slight color shading was detectable and dynamic range is a somewhat limited. In low light and indoors when testing the LED flash, we also observed white balance inaccuracies.

As for video, the Galaxy J2 Pro had generally accurate target exposure in most conditions, and noise levels are pleasingly low in both indoor and outdoor scenes. Autofocus operation is also a highlight with it working quickly and accurately. Areas for improvement include more effective stabilization, some erratic autofocus behavior and unreliable tracing. Like stills, white balance inaccuracies were noted in several test scenes, some exposure inaccuracies particularly with moving subjects and under exposure in very low light scenes (20 lux and less).

Color rendering is generally good on the Galaxy J2 Pro though reds have a tendency to be unsaturated.
Exposure and white balance generally good but occasionally back-lit scenes like this are under-exposed.

Returning to stills, in outdoor scenes the Galaxy J2 Pro is capable of delivering sharply focused and relatively clean images with only a hint of luminance noise. Images have good color rendering outdoors albeit with somewhat unsaturated reds. It also has generally good target exposure though there are times when scenes are occasionally under exposed. White balance is accurate in outdoor conditions however there were noticeable instabilities, and indoors there’s an occasional cast to images.

Limited dynamic range is noticeable in our HDR test scenes, with the Galaxy J2 Pro unable to effectively record details in the shadows.
The device is able to handle some tricky back-lit scene as this shot reveals. The subject is properly exposed although details are lost in the highlights.

Limited dynamic range was also noticeable in our challenging high contrast (HDR) test scene analyses resulting in lost details, particularly in the shadows. In backlit portraits the subject is well exposed but, with details lost in highlight areas, the overall scene isn’t particularly well-balanced. That said, the Galaxy J2 Pro is capable of producing quite acceptable results, though it has a tendency to deliver slightly underexposed images that are also lacking in detail.

Shooting test charts under tungsten lighting at 20 lux, images are only slightly under target exposure but detail remains low.
In very low light levels (5 lux) images are below target exposure, have low detail and show some white balance inaccuracies.

From our tests the camera has fairly well-controlled levels of noise in both outdoor and indoor scenes but luminance noise is noticeable in the sky in outdoor shots, and there’s visible noise in low-light conditions. In our controlled tests in the lab, texture preservation is low even in bright daylight (1000 lux) and details are lost under indoor and low-light conditions. Using the Galaxy J2 Pro’s single LED flash overcomes some of these issues – it has fairly low noise in comparison but detail preservation remains low, white balance is not accurate and there’s some noticeable fall off or shading in the corners from the single LED unit.

After defocusing the device, the Galaxy J2 Pro found focus very accurately after both long and short delays, but as you can see from the spread in the chart above (under low light – 20 lux in this case) it is slow to focus.

Autofocus accuracy is a strong point. The Galaxy J2 Pro may not be all that fast when refocusing between subjects but you can be assured of accurately focused shots. As a fairly basic camera, however, with just a single camera module there’s no optical zoom option nor AI used for the bokeh effects seen in premium devices. Instead the J2 Pro crops the image and inevitably, with the already low sensor resolution, the loss of texture and detail rendition is noticeable.

Uneven sharpness in the plane of focus (in the foreground, below the bushes)  is caused by a bug in the algorithm controlling the OIS mechanism.
Even the best lenses can reveal ghosting when the light source is in the frame but it is  stronger than expected in the Galaxy J2 Pro. 

From close examination you can also expect visible aliasing and edge noise, blue sky saturation, and ringing from slight over sharpening. Some lens artifacts were also detected such as color fringing and irregular sharpness in the plane for focus which is caused by a bug in the OIS algorithm. The bug also contributed in addition to occasional haloing in areas of high contrast small scale detail, such as back-lit leaves and branches. The J2 Pro’s lens unit also has a propensity to ghosting.

When it comes to video the J2 Pro is a relatively strong performer in that field, achieving a similar level to that of stills. It has generally accurate exposure in most conditions, low noise levels even indoors and autofocus operation is fast in all of our tests. It does have some weak areas, however. First, while resolution was satisfactory in daylight, it falls quickly in indoor and low light scenes. Video stabilization is not all that effective and we also noticed autofocus instabilities and unreliable tracking. In some scenes white balance instabilities are visible and exposure variance is occasionally seen with moving subjects. The J2 Pro’s tendency to underexpose with stills is also retained with video. In low light conditions (20 lux or less) clips were below target exposure.


With so much of the internet buzz concentrating on the premium end of the market it is refreshing to see prestigious manufacturers like Samsung catering to a different demographic. Given the camera specs are modest by comparison with the company’s recent high-end S9 and Note 9 models, Samsung have seemingly prioritized other experiences with this particular model. Nevertheless, providing you keep to within practical limits and avoid high-contrast scenes or unduly low light levels, the Galaxy J2 Pro offers quite a respectable level of performance. As for video, the results from the J2 Pro aren’t that far off some of the far pricier higher-end models.
