Test Oppo Find X: an almost successful bet


Tandis that most Chinese manufacturers have chosen to attack the French market from the bottom, Oppo is taking everyone in reverse. To make itself known in France, the brand has chosen to launch a high-end smartphone, offering a screen devoid of borders and notches: the Find X. While refreshing, the Find X forgets that at 999 €, the right to make mistakes is limited and that such a price tag calls for a certain level of excellence.


An borderless and notchless screen.

Ergonomics and design

S 'there is one area in which the Oppo Find X stands out, and that's design. Without totally revolutionizing the world of the smartphone, it has the merit of bringing a little freshness to a world that delights in the notch screen. The Find X, for its part, offers a screen that occupies almost 87% of the front panel. The highest score in our comparison. This display with its slightly curved edges certainly makes its little effect.


La upper part of the smartphone hides a surprise.

For To achieve this result, without resorting to a notch or hazardous placement of the front sensor, Oppo opted for a special mechanism. Indeed, the upper part of the terminal is pulled out of its body to reveal the different photo modules. Here again, the effect is impressive for those who are confronted with it for the first time.


unlocking requires the photo module to be taken out.

problem remains that the only biometric unlocking mechanism is based on facial recognition. This is operated by different sensors placed on the retractable part. It remains more advanced than the facial recognition integrated in Android, since it is based on 15,000 points and 3D data to recognize a face. This system is reminiscent of what Apple offers on its XiPhone with Face ID. All in all, despite the time needed to release the module, the unlocking is quite fast. Put side by side with a Samsung Galaxy S9, the Find X is faster to reach the home screen. Even in complete darkness, the smartphone has no trouble detecting the face.


Pas no mini-jack or microSD port.

La the real question that remains is the durability of the mechanical device. Oppo advances up to 300,000 openings/closings without any problem. Studies conducted in recent years show that our smartphone is consulted 23 to 50 times a day. This gives an assumed lifetime of the Find X mechanism ranging from 16 to 35 years. However, the tests carried out by Oppo were probably performed in a laboratory. They do not take into account the dust that will inevitably get into the gap created when the device is opened.


Anvery good finish.

D 'especially since the Find X has no dust or watertight certification. A negative point at a time when the majority of competitors in the high-end segment have IP67/68 certifications. There is no doubt that the Find X's mechanism is very complex to protect against intrusion. In any case, the finishes remain of an excellent level and the terminal is pleasant to use.

On may also regret the absence of NFC, wireless charging and microSD port. Fortunately, we can still count on 256 GB of internal memory. The Find X, on the other hand, has 2 nano-SIM ports and a USB-C port.


In a high-end terminal that respects itself, the Oppo Find X has a screen in Amoled slab. This allows it to deliver an almost infinite contrast ratio. In addition, it has a maximum brightness of 402 cd/m² and a light reflection rate of 10%, which ensures good readability in full sunlight. In the opposite conditions, the brightness can drop to 2.1 cd/m², ideal for not being dazzled in the dark.

Oppo could on the other hand have taken more care with the colorimetry of its screen. We measured a delta E at 4.5, which, without being catastrophic, is very disappointing for a high-end smartphone. The majority of competitors now fall below 3, a value from which the human eye detects more drifts. To obtain an optimal color temperature, you have to go through the parameters and choose the warmest mode possible. Once this setting is applied, we measure a near perfect temperature of 6,537 K.

Avec a diagonal of 6.4 inches (16.26 cm) for Full HD+ definition (2,340 x 1,080 px), the Find X offers a comfortable resolution of 402 dpi. The responsiveness of the display is quite good with a tactile delay measured at 91 ms and zero afterglow.


Oppo has chosen one of the best platforms available with a Qualcomm Snapdragon 845 SoC. The 8 cores that make up the latter and the 8GB of RAM that comes with it are more than enough to provide a smooth experience in all circumstances. Regardless of the applications it is used for, the Find X maintains its speed of execution. There's nothing wrong with that.

Côté graphics, the Adreno 630 chip also ensures an optimal level. 3D games, even the most demanding, run smoothly in their best light. The Oppo Find X is a mobile gaming console perfectly at the level of its competitors.


Find X has no 3.5 mm mini-jack plug. Therefore, a Bluetooth headset is required or use the supplied USB-C adapter. The latter is pretty good overall. It delivers comfortable power, without much distortion. We also measure a dynamic range with a nice width. The stereo image reproduction is in the average.

Avec its borderless design, Oppo didn't have the space to fit speakers in the front. So there is only one speaker on the lower edge of the device. If it is powerful enough, it is clearly missing. The highest frequencies are penalized by a marked distortion. The whole thing lacks depth and lends itself more to short voice-centric videos than to music.


In its sliding part, the Find X integrates two backside photo modules. The first one is based on a 20 Mpx sensor and the second one on a 16 Mpx sensor. Both are surmounted by an f/2 opening optic. As for the unlocking, the part hidden in the smartphone body comes out when the photo application is opened. This device slows down somewhat the first shot. It takes a few hundredths of seconds longer for the Oppo Find X to take a picture compared to a Galaxy S9. In use, this is not too much of a handicap either.

Toujours is that the Find X does not rise to the level of the best smartphones in the photographic exercise. In broad daylight, there is a good dose of accentuation and smoothing that makes you lose the smallest details. The Find X also has an unfortunate tendency to overexpose, with bright areas burned out, even with HDR turned on. HDR has the additional disadvantage of making the shooting less responsive. It has to be deactivated in order to take a quick succession of shots.

In low light, the Find X is not ridiculous and manages to provide a properly exposed scene. However, you have to deal with electronic noise, which is painfully controlled by smoothing. The colors are particularly blurred and the quality of the edges of the images drops drastically. A disappointing result, especially since the Find X does not trigger very quickly on our test scene (1/9 s). This low speed doesn't prevent it from going up to more than ISO 6,000, which its small sensor can't manage efficiently.


portrait mode of the Oppo Find X.

second module does not intervene surprisingly for the zoom proposed by the Find X. It is thus only a digital zoom, coming "cropping" in the main sensor. The second sensor seems to intervene only for the creation of a background blur in the portrait mode. The bokeh thus created is as often rather average, without progressiveness and imprecise when the background is too complex.


Les two photo modules on the back.

front module of 25 Mpx does not gratify the selfies of great finesse. The smoothing is far too present to be able to detect a difference with a less defined sensor. On the other hand, the exposure management is right and the backlighting is under control.

Les video enthusiasts will not be excellently served. Whether we record in Full HD or UHD, videos suffer from jerks and exposure transitions are brutal. Focus tracking is precise, but lacks a bit of velocity.


Find X comes with a 3,400 mAh battery. He is one of the best students in endurance, without going for the strongest in the discipline. On our SmartViser test protocol, he ran for 15h34. A score that puts him ahead of aLG G7or anOnePlus 6, but behind theHuawei P20 Pro,Samsung Galaxy Note 9orHonor View 10. In practice, the Find X lasts about 2 days in standard use. The more relentless users will need to go through the recharge box at the end of the evening.


One of the big assets of the Oppo Find X is its fast charging technology that allows it to go from 0 to 100% in about 30 minutes. A feat that can only be achieved with the charger supplied by Oppo, capable of up to 50 W.
