Test OPPO Reno2 Z: a beautiful case that misses the mark in the photo


Oppo is trying to occupy the field by releasing a new mid-range smartphone, but with premium finishes. The Oppo Reno2 Z is a lighter version of the Reno2, but it is still a smartphone with a few advantages. Launched under the symbolic €350 bar, it fits into a sector where competition is fierce. Thus, it is in front of theXiaomi Mi 9T or Google Pixel 3a, which is formidable in pictures. Also, we can oppose him a Honor View 20. And if finally his worst enemy was not simply theReno Z?


Reno2 Z, in the purest Oppo tradition.

Ergonomics and design


An "Full" screen.

Oppo has made the "full screen" screen on smartphones its trademark. The firm has thus become a specialist in slabs without notches or punches. The Oppo Reno2 Z is a mobile with exemplary finishes, whose large 6.55-inch screen occupies more than 86% of the front panel. Only a thicker black border at the bottom of the terminal denotes. The selfie module is therefore concealed, not in a retractable fin, as is usually the case on Oppo mobiles, but in a small "pop-up" square.


Reno2 Z, no frills.

In hand, the smartphone, although a little heavy (nearly 200 g), offers a high-end feel, all glass. The buttons fall easily under the fingers and the unlocking of the device by a fingerprint sensor placed under the screen is reactive. On the back of the camera, the color effects are quite successful and we find the small steel ball, another Oppo's hobby. It is used to absorb shocks instead of the four photo sensors module.


An nice back.

For To complete this overview, let's recall that the terminal has 128 GB of storage, of which a hundred or so are actually available. It is able to accommodate two nanoSIM cards or a single SIM card and a microSD card. The only drawback is the lack of waterproof certification, due to the retractable camera.



La take mini-jack is at the rendezvous.

La 3.5 mm mini-jack socket is positioned on the bottom edge of the Reno2 Z, and it offers good results. Its distortion is quite contained, the crosstalk allows a good stereo reproduction, while the dynamic range is quite wide. Finally, we can't say that the plug lacks power, nevertheless, we hoped for better. A headphone that uses a little too much power will not give all its measure with this connection.

For the external sounds, the single speaker is quite correct, but, as often, you should avoid pushing it too far or it will saturate.



Anslab of the most beautiful effect.

Avec the Reno2 Z, Oppo still makes the choice of a "full screen" screen. The 6.55 inches of the Amoled panel cover almost the entire front surface of the mobile. Covered with Gorilla Glass 5, the screen has a definition of 2,340 x 1,080 px (resolution of 394 dpi). When we started our measurements, the default optimization quickly showed shortcomings. Indeed, the screen was too bluish, and the measured color temperature confirmed this feeling by displaying more than 7,500 K, far from the 6,500 K expected. By setting the temperature to "warm" in the display parameters, we obtained 6,686 K, a very satisfactory level.

In Regarding colorimetry, our probe detected a delta E at 4.1, beyond the threshold of 3 - below which the human eye cannot perceive the drifts. It is in particular the fluorescent green, turquoise and yellow shades which are the most out of standard. Nevertheless, this is hardly noticeable and the display remains quite natural.

Alors that theReno2 offered a maximum brightness of 737 cd/m², the Reno2 Z is content with 438 cd/m². However, this luminosity, associated with a contained reflectance, and an almost infinite contrast ratio (thanks to the Oled), does not pose a problem for use in full sunlight. At night, the minimum luminosity was measured at 2.1 cd/m², which does not burn the retina. Finally, the tactile delay measured at 73 ms is in the average of the latest smartphones of the brand and allows the display to remain fluid.


Sous the hood of the aircraft, Oppo has renewed the Mediatek SoC Helio P90, already present on theReno Z. However, the Chinese firm's teams have decided to double the RAM memory, which now stands at 8 GB. In reality, this does not translate into a massive gain in power. In our multitasking test, the Reno2 Z even did a (tiny) bit less well than its predecessor, with 93.25 points versus 93.50. Otherwise, this score is more than honorable and Reno2 Z will have no problem with everyday actions.


Lors of the game test, it is much worse, with an index at 25.45, and less than 15 fps on average. So we can't say that this mobile is made for gambling. 2D titles should work more or less smoothly, but more demanding games will have a hard time staying playable, even with some effects turned down.


Anheats more than controlled.



4 sensors, but only two can be used in practice.

We are at the end of 2019, so a smartphone must have more than three photo sensors. For his Reno2 Z, Oppo has installed no less than four. The Chinese manufacturer is reusing the 48-megapixel Sony IMX sensor and an f/1.7 lens (equivalent to 26 mm in 24x36) as the main module. It is supported by an 8-megapixel sensor, with an ultra-wide-angle lens (18 mm equivalent). Finally, the terminal is supported by two 2-megapixel sensors, both with an f/2.4 lens. They are used to optimize portrait shooting and add two filters.

Par Alternatively, the Reno2 Z outputs 12 megapixel shots using aupixel binning to merge 4 pixels into one. Compared to a 48 megapixel image, in daylight the differences are not obvious. The two images are very similar, the 48 megapixel photo appears a little more contrasty and the details are more accentuated. Also, optical distortions are better managed when recording in definition maximum

Normalement, it is in low luminosity that lepixel binning takes all its meaning. Here, it must be noted that the difference is not obvious. We can just notice that the photo taken at 12 megapixels is a little smoother and therefore limits the noise.

For the main module, we wanted to oppose Reno2 Z to Google Pixel 3a, given their similarity in price. By day, the Oppo shots are of good quality, but the global rendering is a bit too hot and the optical distortions are quite marked at the periphery of the image. Pixel 3a exposes the scene a little better, the colors are more faithfully reproduced and the optical aberrations much better controlled.

Quand the light is running out, it's another round easily won by the American smartphone. While it offers a much more limited increase in ISO, Pixel 3a offers more natural colors, a more accurate exposure and a more contained smoothing. Indeed, Oppo photos tend to "drool", and tend to be too red-hot.

UGA module is now classic, but some manufacturers are struggling to master it. Here, by proposing a low definition sensor (8 vs 16 megapixels for theXiaomi Mi 9), and limited software work, Oppo does not provide its Reno2 Z with the best possible quality. The shot lacks sharpness and appears almost blurry, optical aberrations are very pronounced and colors are not very accurate. The contrast is total with the Mi 9, which offers a much more correct image.

   data-src=    data-src=

Par With lower brightness, the Reno2 Z's UGA module reproduces an unusable image, colors are poorly rendered, and shapes and details are missing. The Mi 9 shot is not exceptional, but thanks to better definition and more efficient processing, the image is still acceptable.

In the photo application, the Oppo Reno2 Z encourages to use a x2 zoom, then x5. This intrigued us since this terminal does not have a telephoto lens module. It is simply a digital zoom made by cropping in the image. However, no software processing is applied (or at least at least), and as you can see, at x2 and even more at x5, the result is not really usable, unless you like "pixel art".

Mode portrait, front camera and vidéo


Petite pop-up camera.

portrait mode is not forgotten on the Reno2 Z. With two spot sensors (2 megapixels each) for improved image capture. The subject is fairly well cropped and the blur applied can look natural if you don't zoom too much into the hair. For the selfies, we are quite satisfied with the image processing done by the 16 megapixel sensor. By default, the smoothing is very discreet and the subjects do not appear too glossy. Finally, the Oppo Reno2 Z is able to shoot up to 4K, but only at 30 fps. The 60 fps is reserved for 1080p. Autofocus is quite responsive, transitions are smooth, and stabilization does a good job.


For ensure the power supply of its smartphone, Oppo uses a battery with a capacity of 4,000 mAh. During our SmartViser autonomy test (simulating a daily and rather intensive use), the device turned off after 22 h 59 min. A very good score that gives it a theoretical autonomy of more than 3 days. Which is always appreciable.


Concernant the reloading time, we are a little bit disappointed. Indeed, the phone is compatible with the home fast charge, "VOOC 3.0". With the supplied power pack, it took a little over 2 hours to fully charge the Oppo Reno2 Z. We had a right to expect better.
