vivo teased the S5 earlier this week and today the company announced the smartphone will be unveiled on November 14 at an event in Hangzhou, China. The company made the announcement by posting a video on Weibo. It doesn't reveal much about the S5, but the smartphone was spotted in a video last week with three cameras on its back arranged in a diamond-shaped formation. Details are scarce about the vivo S5 right now, but seeing how the S1 and S1 Pro were photo-centric devices, we expect the S5 to be aimed at the same audience and come with a 48/64MP primary camera and a 32MP...

Huawei MatePad Pro leaks with slim bezels, punch-hole camera, stylus
A couple or so weeks ago an unannounced Huawei tablet leaked in some official-looking (yet low quality) renders, showing a punch-hole display housing a selfie camera in one corner, incredibly thin bezels for a tablet, a keyboard accessory, and a stylus that magnetically attaches to the tablet's top side. Today Evan Blass, aka @evleaks, has outed a new press render of the same device, and also provided us with its commercial name. It's going to be called Huawei MatePad Pro, and not MediaPad M7, as previously rumored. Given the design, stylus and keyboard support, and the name, Huawei...

Honor 20 Pro front camera review
Announced in May 2019, the Honor 20 Pro is the latest top-end device from Huawei’s budget-friendly sub-brand. The phone’s specifications are impressive, featuring a 6.26-inch LCD, a high-end Kirin 980 chipset, and 8Gb of RAM. Its quad-cam setup performed admirably in our rear camera tests—ahead of some of the more expensive flagship competitors. Its front camera features a high-resolution 32MP sensor coupled to an f/2 lens for stills, and 1080p video with gyroscope-enabled Electronic Stabilization (EIS). Read on to see if the Honor 20 Pro can also [glossary_exclude] punch [/glossary_exclude] above its weight in our DXOMARK Selfie tests.
Key front camera specifications:
- 32 Mp sensor with 0.8µm pixels
- f/2.0-aperture lens
- 1080p/30fps video with gyro EIS
About DXOMARK Selfie tests: For scoring and analysis in our smartphone front 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. For more information about the DXOMARK Selfie test protocol, click here.
Test summary
An overall score DXOMARK Selfie score of 85 points puts the Honor 20 Pro outside the top 10 in our database, instead seeing it nestling in between the OnePlus 7 Pro at 85 points and the iPhone XS Max at 82. Achieving the same score of 85 for both Photo and Video, the device is competent in both areas and gets many of the basics right.
Exposures are accurate and white balance is neutral in all lighting conditions; and although dynamic range is slightly limited compared to the top performers, highlights are often well-preserved in bright scenes. Bokeh shots display some depth estimation failures and more limited dynamic range, but the depth-of-field effect is pleasant, with good noise uniformity and repeatable results. In low light, noise is well-controlled and overall exposure is very respectable, but detail is low, with unnaturally-rendered skin tones and limited dynamic range. You can see in the low-light example (below right) that highlights and deep skin tones are clipped and fine detail is lost.
Focus and artifacts are the Honor 20 Pro’s main opportunities for improvement. At close (30cm) and medium (55cm) range, faces are in focus and details are fairly well-preserved in indoor and outdoor shots. Depth of field (focus) is narrow, however, so faces behind the first person in a group portrait are out of focus, and there’s a noticeable loss of detail in the background. Many artifacts are also visible, including color quantization, loss of sharpness in the corners, flare, facial distortion, and color shifts on faces. Accurate exposure using flash is another strength, however, and although some corner shading, loss of detail, and luminance noise are all visible, overall flash results remain pretty acceptable.
The Honor 20 Pro performs slightly better for moving images on the front camera. A video score of 85 points puts it in the top 10 of devices we’ve tested, and its strengths of accurate exposure, neutral white balance, and well-controlled noise ensure nice results in most conditions. Slight underexposure and a loss of detail is evident in challenging low-light conditions, and the jello effect is often visible when capturing moving subjects—but even so, the Honor 20 Pro does a pretty solid job for video.
Conclusion
Although the Honor 20 Pro doesn’t challenge the top performers overall, good exposure, white balance, and noise control ensure that it delivers pleasant selfies in most conditions. Add to that a good video performance, and the front camera is a competent, if not stellar, addition for those primarily interested in this device’s impressive specs and excellent main camera.

Fairphone 3 camera review
The Fairphone 3 is the latest modular offering from the Amsterdam-based Fairphone company. For those unfamiliar with Fairphone devices, they are designed to allow users to easily replace parts (battery, camera, speaker, screen, etc.) so as to extend their life and reduce their impact on the planet.
The single camera comes with a 12MP sensor and f/1.8 lens. The device runs on the Android 9 OS, is powered by a Qualcomm Snapdragon 632 processor, and comes with 4 GB of RAM and 64GB of storage (along with a slot for a microSD card). Read on to see how the Fairphone 3 performed in our DXOMARK Camera tests.
Key camera specifications:
- Single camera
- 12MP sensor
- 27mm-equivalent, f/1.8 aperture lens
- Dual-pixel PDAF
- Dual-LED flash
- 4K video @ 30fps
About DXOMARK Camera tests: For scoring and analysis in our smartphone camera reviews, DXOMARK engineers capture and evaluate over 1600 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. For more information about the DXOMARK Camera test protocol, click here. More details on how we score smartphone cameras are available here.
Test summary
The latest Fairphone is capable of taking usable images under good shooting conditions, but with an overall DXOMARK Camera score of 66, it barely stays ahead of the Samsung Galaxy J2 Pro from 2018 (whose score of 65 may improve after we retest it for Wide and Night). It’s comfortably ahead of the lowest smartphone in our current ranking (the budget-friendly Altice S61 at 56 points), but it should come as no surprise that it is nowhere near any flagship devices when it comes to providing good image quality in challenging situations. (Note that as the Fairphone 3 has no wide-angle camera module, we did not test or score it for Wide.)
For still images, the Fairphone 3 achieves an Exposure sub-score of 73. Its limited dynamic range means that bright zones are sometimes blown out and dark zones are often clipped. Moreover, there are strong exposure instabilities between consecutive shots, with HDR sometimes triggering, and sometimes not, so you might need to take several shots to get something truly usable. In the images below, the Fairphone image is darker and has fewer details visible in the shadow areas than the image from the Galaxy A50; the iPhone image, however, shows the most detail in the dark areas, along with good color and detail in the sky.
In the high-contrast comparison images below, you can see that not only is the Fairphone image underexposed, it also has a very strong pink color cast. Both the A50 image and XS Max do a much better job with this scene.
Indoors, target exposure is generally accurate for scenes without challenging high contrasts, as shown in the left-hand image below; but as you can see in the right-hand image, the Fairphone 3 does not handle backlit portraits well.
As mentioned above, Fairphone images tend to show a strong (usually pink) color cast, particularly outdoors, as well as strong color shading. Further, color fidelity is inaccurate, as shown in the color chart, below left: at 5 lux (left-most patch), all colors have low luminance; and although color improves at 100 lux, it is still far from accurate. Still, colors are generally well-saturated, which is a plus—although sometimes they can be oversaturated, as you can see in the light red area on the left of the real-life photo below right.
As for autofocus on the Fairphone 3, it is accurate; however, the delay between defocusing and refocusing can sometimes be quite long (>300ms).
The level of texture and detail in outdoor shots is good, and even in low-light, the level of detail is acceptable. However, shots often show an unnatural rendering of details, and many show a strong ringing effect, as shown in the photos below.
The Fairphone 3 controls noise pretty well in low-light conditions, but coarse noise in uniform areas (such as the sky) can be visible in outdoor shots; further, strong chromatic noise in the field (in which the level of noise is higher in the corners than in the center of the image) is visible in both indoor and outdoor images, as in the sample photo below; note also the cyan shift in the upper left corner.
Besides the problem with ringing mentioned above, other artifacts that affected the Fairphone’s Artifacts score include flare and noisy edges (the latter shown below).
The Fairphone 3 did not achieve a high score for Night (33), nor does it have a Night mode. As you can see in the portrait taken with flash only (0 lux, left), the target is significantly underexposed; there is strong chromatic noise in the corners, and the red-eye effect is very noticeable. Under 5 lux lighting, however, there is good target exposure, although there is still strong chromatic noise in corners and strong color shading overall.
With flash in auto mode, portrait target exposure and detail preservation is generally acceptable on the face, but details in the background are completely lost. With flash off, white balance has a strong yellow cast under sodium vapor lights; and as mentioned in the color section above, other flash-off night shots sometimes show a pink cast. [REMOVED “and/or blue”]
In cityscapes, strong chrominance noise is visible when flash is activated; with flash off, the noise is somewhat lower. In very low light when flash is off, targets are often completely underexposed. In the night cityscapes below, for example, all taken with flash off, both the Xperia 1 and the A50 provide more details on the crane in the foreground than the Fairphone. The sky in the A50 image has a higher exposure than the other two, but is far noisier, as you can see in the crops.
The Fairphone 3’s zoom performance at medium range is poor, even compared to many other devices which also have no tele-lens, although its zoom images tend to have low levels of noise in uniform areas. Unsurprisingly, given its tele-lens module, the Xperia 1 shot is much crisper; the Fairphone shot is fuzzier and its strong pink cast is very noticeable as well.
Due to its single camera, the Fairphone 3’s bokeh has no depth estimation; it relies solely on its ability to detect a person in an image, and then blurs everything else. This means that subject isolation is often inaccurate, and the device blurs objects that ought not to be blurred, such as the cup that the subject is holding in the photo below on the left. Moreover, the Fairphone has no HDR in bokeh mode, which is a serious drawback. The Galaxy A50 (middle) does a better job, even though the overall image is somewhat overexposed. The iPhone XS Max does the best of the three, but even with a dual-cam setup, it does not blur the foreground as it should.
In video mode, the Fairphone 3 records 4K video at 30 fps by default. Even so, its overall performance was disappointing; in fact, without having achieved a decent score for artifacts (71, after deducting points for noticeable cyan shift and moiré), its score both for Video and Overall would have been significantly lower.
Much as for stills, video dynamic range is limited in challenging scenes—bright skies are often blown out, and details in the shadows are lost. (This said, detail preservation is fairly accurate in indoor conditions.) White balance has a pink cast, and white balance adaptation is sometimes abrupt. The factor that most affects pleasant playback is stability, however, and the Fairphone 3 unfortunately does not do well in this regard, especially for hand-held videos recorded when walking. And in addition, chromatic noise and blocking is very noticeable in low-light conditions, as you can see in the frame capture below.
Conclusion
The Fairphone 3 is designed to factor in the human and environmental costs of smartphone manufacturing and disposal. As with other phones with relatively low-cost components, of course, it does not have a camera module that any serious photographer or videographer would choose for its image quality. Nevertheless, the reality is that while it is not great for shooting video, the Fairphone can produce largely usable moving and still images under many common shooting conditions; and with the exception of underexposure, what flaws and faults there are simply aren’t noticeable on a small display. Near-chronic underexposure is a problem, though, as is its near-omnipresent pink cast.
This all said, given the company’s goal of providing a smartphone that has smaller-than-usual ecological footprint, we hope that Fairphone will improve the image quality of its camera so as to make it more competitive in the market.
