A smartphone with edge-less display, without notch that hides the front, and rear camera in a retractable module – Oppo Find X redefines smartphone design in 2018. A 6.4-inch AMOLED Curved Display without bezels is in your hands. There are permanently visible cameras neither on the front nor on the rear. These are hidden in a pop-up module. Like all real flagships currently, the Oppo Find X is powered by a Snapdragon 845 and there is at least 8/128GB storage. A dual camera and a well-dimensioned 3730mAh battery are also available. Newly discovered features like an in-display fingerprint sensor and wireless charging are not included in the Oppo Find X. If you want to enjoy the extraordinary design with pop-up camera, you have to pay 927$ – quite expensive. We have tested the Oppo Find X for 10 days and in this review you will find out for whom this investment is worthwhile. Welcome to the future!
Digression: Together with Vivo, Oppo is one of the strongest Xiaomi competitors in China. The parent company BBK-Electronics also includes the globally successful manufacturer OnePlus. Oppo’s last really impressive smartphone was a long time ago. Oppo Find 7 is now followed by Oppo Find X and creates something most manufacturers only dream of. Since the end of 2017 only 2 smartphone designs exist: 19:9 smartphones with notch and tri-bezel-less smartphones. The notch trend comes from Apple and Xiaomi, with their Mix series, is responsible for the tri-bezel-less design. The manufacturers’ ultimate goal is to hold just one piece of display in their hands. The Vivo Nex could already fulfill this project by integrating the front camera into a retractable module. The Oppo Find X goes one step further: Both the front and rear camera are housed in an extendable module on the top. The balance of power of the mobile phone manufacturers is now even more shaky. Where Apple once only wanted to produce cheaply, innovations are now emerging to which Apple must respond.
Design and build quality
The Oppo Find X is a true full-screen smartphone. A long-awaited dream finally comes true. The clean design of the rear is probably the most impressive thing about the phone. Since the front and rear cameras are completely hidden under the extendable module, the design is phenomenal. The glass rear shimmers in curved design either in bordeaux red or glacier blue. The Oppo Find X consists exclusively of glass and metal. The front and rear are strongly rounded (3D glass) and protected from scratches by Gorilla Glass 5. A thick display protection film is applied ex works. The rearside of our bordeaux red test device is rather black in the middle and then merges into the painted frame in a discreet red-purple. The colouring is rather purple than red, just like a good Bordeaux from France. The bezels are small with 2.5mm and appear even narrower due to the curved glass. Above the display there are only 2mm and below 4.5mm. The entire frame of the smartphone moves up 10mm when the camera or face unlock is activated, exposing the front camera and the dual rear camera.
At which point the smartphone expands is neither haptically nor optically well recognizable. A half moon on the upper side reveals the right spot. The motorized camera module can also be reluctantly pulled out with a fingernail, shortly after which it moves back into position. In the extended position, the module is easy to move to the left and right, but overall the construction appears sufficiently stable. The only problem is that Oppo only relies on the Face-UNLOCK and did not install a fingerprint sensor (especially an in-display fingerprint sensor). This means that the camera module has to move up and down each time the phone is unlocked. This definitely causes enormous wear and tear. An average mobile phone user will thus activate the camera 35,000 times per year just for unlocking the smartphone. According to Oppo, however, the mechanism can withstand 300,000 camera movements and therefore survive 7-8 years without any problems for an average European. The only option to spare the engine would be to use old unlock mechanisms like patterns or pins, but that’s no fun anymore in 2018 and every 55$-smartphone beats the Oppo Find X at unlock speed. Fortunately, the 3D Face Unlock works excellently when it comes to safety and speed. Even with extending the camera, the unlock happens in less than a second and even in the dark the recognition is not impaired. FACE-ID cannot be tricked with simple pictures or videos.
The Oppo Find X is 157mm long, 74mm wide and with 9.6mm quite thick compared to current flagships. On the other hand, there is also a well-dimensioned 3730mAh battery and the retractable module also takes up space, of course. Due to the conical shape of the rear, the Find X doesn’t look oversized or overweight at all, which it isn’t with 186g either. Compared to the Xiaomi Mi A2, the Oppo is therefore more compact in terms of dimensions, although the display is 0.5 inches larger. The Oppo Find X is also more compact than a Samsung Galaxy S9+ with 6.2-inch display, although only 2mm. In terms of screen-to-body ratio, the Oppo Find X is unbeaten! The brightness and proximity sensors are located below the display and work smoothly.
Oppo uses on-screen keys, as there is no room for anything else. Alternatively, you can operate the smartphone by wiping gestures, as you know it from iPhone X or Xiaomi. In daily use, operating the phone works very well. The SIM card slot is a bit special. First of all it is protected with a rubber flap against penetrating water, nevertheless, the Oppo has no IP certification due to the pop-up module. In addition, the two Nano-SIMs (storage expansion is not possible) are clipped to the top and bottom of the SIM card holder. Funny, but it works well. Unfortunately you have to do without a jack connector, but there are USB-Type-C headphones in the scope of delivery. Oppo also supplies a VOOC (Dash Charge known from Oneplus) adapter with 5V and 4A. Furthermore, you will find in the box the obligatory USB-Type C cable, a USB-Type-C on jack adapter and even a hard plastic cover. This cover is rather thick, but it’s nice that it’s included, because finding covers for the Oppo Find X is not that easy due to the pop-up module.
Instead of a notification LED you have Oppos Curved Panoramic Light effect in form of a glowing circle at your disposal. However, it only occurs twice after a notification has been received, presumably to save battery power. It is hardly a real replacement for a notification LED, but the shining circle around the edges simply looks outstanding – a pity.
You can hardly react to the Oppo Find X with another expression than “WOW” . The pop-up module leaves the device in 0.5 seconds and the unlock with Face-UNLOCK works perfectly. I almost like the clean design best, without visible cameras and in combination with the really successful colour play of our Bordeaux red version. The relation between display and dimensions is unique and if you are looking for the special kick when buying a smartphone, you should consider the Oppo Find X. What Xiaomi does with the mix smartphones is cool. But what Oppo has created with the Find X is simply madness.
With a 6.42-inch Full Screen Curved AMOLED display, the Oppo Find X is the only smartphone in the world that really deserves the title “bezel-less”. The Oppo Find X (without notch) has a resolution of 2340 x 1080 pixels with a display ratio of 19.5:9. Even if the resulting 401 pixels per inch are not outstanding, the display of the Find X is as razor sharp as any other flagship display. The AMOLED panel is slightly curved, as known from the Samsung Galaxy S9, and protected from scratches and falls by Gorilla Glass 5.
The AMOLED display offers strong colours, which are however also somewhat unrealistic. However, this is normal with AMOLED panels. The display settings are reduced to a minimum compared to Xiaomi. Cold, normal and warm are available and the contrast cannot be adjusted at all. The contrast is AMOLED typically awesome and the Oppo Find X offers real black without background lights. The display also scores well in terms of brightness and the readability outdoors is excellent.
The touch screen processes up to 10 inputs simultaneously and always does that accurately and quickly. Oppo does almost everything right with the Find X’s display. The display is bright, sharp and colourful. Only in terms of the settings, they could have provided more options. Smartwake functions like Double-Tap-To-Wake-Up are of course also available in the Color-OS system.
System and performance
The Oppo Find X gets its speed from a Snapdragon 845 processor. The Octa-Core processor works with 8 Kryo cores and is supported by a very powerful Adreno 630 GPU. The SD845 is one of the fastest mobile phone processors in the world and is also used in the following other flagships: Asus Zenfone 5Z, Vivo Nex, Xiaomi Blackshark, Xiaomi Mi8, Xiaomi MI Mix 2S and Oneplus 6. All versions of Oppo Find X have at least 8GB RAM and 128GB storage. Only with the internal storage you still have the option to use 256GB. Thus, the storage equipment is great. The benchmarks are on a level with the devices just mentioned and with Oppos own Color OS, the system runs extremely fast and smoothly.
The 8GB RAM has a speed of 10.5GB/s, which is flagship worthy; concerning the speed and multitasking there are no limits. Nevertheless, apps are regularly terminated in the background to save battery life. Therefore, you have to activate apps, which should check messages in the background (e.g. WhatsApp or Gmail), in 3 different places. The internal storage is a current UFS 2.1 storage and works also fast with a speed of 767/200 MB/s.Antutu Result Geekbench Multi Result Geekbench Single Result 3D Mark Result
No matter which game you open on the Oppo Find X, it runs smoothly and without lags even in high details. The Oppo stays cool even after one hour of playing PubG, although Antutu gets a bit slower after 4 runs. The heat development at the rear of the glass is harmless and you won’t notice that the processor is clocked down a bit after heavy use during normal operation. The Oppo Find X delivers exactly the performance you would expect from a current flagship with SD845 processor. There is enough fast storage and under Color OS the Oppo Smartphone executes all commands without problems.
Color OS V5.1 on Android 8.1 basis
Oppos Color OS of course receives regular updates and the Google security patch is also kept up-to-date. The system belongs to the strongly adapted custom UIs and there is hardly anything left from Stock Android as it is known from the Mi A2 or A2 Lite. In the 10-day test phase, Oppo provided us with 2 updates, so the chances are good that Oppo will take care of updates for a long time.
When first starting the Oppo Find X, you will miss the Google Play-store, but there is also a Global Version, which has the Play-store directly on board. The Global Version should already offer various languages. Apart from the Play-store, you also have to get rid of a huge pile of pre-installed apps. So-called “Top-Apps” and “Popular Apps” can easily be uninstalled, only the apps with “Oppo” in the name have to stay. But they don’t interfere if they are pushed into a separate folder.
Color OS belongs to the operating systems without app drawer, so every app is placed on the home screen and can be organized in folders. The quick launch bar is customizable and clear and also in the options menu, you can find your way around with a little practice. Unfortunately, you can’t change the launcher. Again and again, you get the default launcher, the option to prevent this is simply missing in Oppo Find X. In the system, you navigate either with on-screen keys (of course freely definable in their arrangement) or with various gestures. The gestures replace the back, multitasking and home commands excellently, as you already know it from Xiaomi’s full-screen gestures or from Apple.
The notification settings for Color OS are a bit tiring. The system rigorously blocks the background use of all apps, so you first have to adjust 3 settings so that WhatsApp can unperturbed work in the background. Under “App Management” deactivate the “Power Saver” and allow the “Auto Start”. Then disable the “App Quick Freeze” under “Battery”. Even then you still have to lock WhatsApp as a background app in the multitasking overview. Then you get WhatsApp messages just like on any other device. If you find a better solution here, please comment 🙂
Otherwise, there are still some additional functions to discover and also a theme manager for the optical adjustment is available. To use other themes you have to create an Oppo account. You can clone WhatsApp directly in the system without additional app, for dual-SIM operation and beside edge gestures there are still some little things to discover. The Widevine level is L3, so you can’t use Netflix and Amazon in FHD, unfortunately. In summary, Oppo’s Color OS is very colourful and functional and also sufficiently clear. You can definitely get used to the system and the performance is excellent.
The Oppo Find X has of course a dual camera set-up, but BBK-Elektronics works without rhyme or reason. As with the Vivo Nex and Oneplus 6, the second sensor is also an ordinary standard sensor. No telephoto lens, native black/white sensor or huge lens aperture for low-light support. The main sensor is a Sony IMX 519 with 16 megapixels and f/2.0 lens aperture. The pixel size of 1.22µm is large enough for good low-light shots and the sensor is also optically stabilized. The second sensor has 20 megapixels and smaller pixels with 1 µm and also the aperture remains identical with f/2.0. In my opinion, the only task of the second sensor is to find the background in bokeh shots. This is somewhat little for a flagship phone like the Oppo Find X. Even if there is a 1x and 2x zoom button in the camera UI, this is a pure digital zoom. Otherwise, the camera app is clearly arranged with well-known functions like portrait mode, auto HDR, panorama, beauty mode and also an expert mode is available. Even if the Oppo Find X houses only one lonely LED, it has a lot of power and is sufficient for good night shots.
The bokeh shots belong to the better of their kind. The separation of foreground and background usually succeeds at the first attempt and is well implemented without disturbing transitions. In addition, you can define light filters for the so-called portrait shots, but they don’t really provide any added value. If you like bokeh shots, the Oppo Find X can create them very well.
The image quality of the 16 megapixel main sensor is on a par with the smartphone elite in good lighting conditions. The pictures have many details, a very good contrast and lively, but not yet oversaturated colours. You hardly have to use the HDR mode, because the contrast is very nice even without it. Sometimes HDR is almost too much of a good thing. Irrespective of what the second sensor really does for night shots, the results are impressive. Detailed, rich in contrast and still pleasantly sharp, even shots in poor lighting conditions are successful.
The Oppo Find X is a true selfie master. Not only the high 25 megapixels with f/2.0 aperture impress here. The selfies taken with Auto-HDR have many details, are pin sharp and offer outstanding contrasts. If you are into beauty mode, you can subject your face to a 3D scan and then have the AI make individual adjustments to your face. Bokeh selfies are of course also possible and, like the normal bokeh shots, deliver very good results.
For video recordings 4K and 1080p are possible, but with a maximum of 30 FPS. Oppo is a bit behind here. Also an EIS is missing and so it is only stabilized via the OIS. The stabilization works fine at 1080p, but at 4K it’s not noticeable. Here, you can hope for an update, but for now, you have to live without stabilization with 4K videos! Slow Motion is of course also possible. The sound quality of the video recordings is at most on average and not really convincing. On the other hand, the 4K videos as well as the normal recordings score well when it comes to quality. In particular, the outstanding dynamic range clearly helps the video recordings and provides an excellent result with many details, sufficient sharpness and vivid colours.
Connectivity and communication
The Oppo Find X offers the latest reception standards and provides network frequencies for the whole world:
- GSM (2G): 850/900/1800/1900
- UMTS (3G): B1/2/4/5/6/8/19
- TD-LTE B34/38/39/40/41(2496-2690MHz)
This is extremely practical, as you can always insert an additional SIM in the dual SIM mobile phone abroad. One SIM card is facing down in the slot and the other is facing up. The SAR values are comparatively very high with 1.57 head and 1.658 body, but the reception strength is also good. The call quality is excellent and ambient noise is reliably filtered by an additional microphone on the top. The hands-free speaker can also be used, but the noise-suppressing effect is no longer present here.
Bluetooth 5.0 and WFi with ac standard in the 2.4 and 5GHz network both do their job without interruptions. The WLAN even works remarkably fast and with a very good range. OTG is supported, but you have to do without NFC with Oppo Find X.
The phone provides the standard sensors with acceleration, proximity and brightness sensors. Additionally, a gyroscope and an e-compass are available. The compass is especially useful for pedestrian navigation and the GPS reception of the Oppo Find X is excellent. The position is determined with lightning speed to an accuracy of 2-3m and a fix is still possible even in buildings. In addition to GPS and GLONASS, GALILEO is also used to determine the position.
Instead of the usual stereo loudspeakers, the Oppo Find X has a mono loudspeaker on the bottom. It is one of the louder ones and even bass is perceptible. The included Type-C headphones have an average quality and are also not very loud. Nevertheless, thumbs up for the “free” headphones. If you connect good headphones via the adapter, you also get good sound.
Surprisingly lavish for a flagship, the Oppo has a relatively large 3730mAh battery. For a flagship with so much power and such a huge display, the battery life of the Oppo Find X is simply great and it performs better than the competition. It’s hardly possible to drain the battery in one day. In the test mode, with 8-9 hours DOT (display-on time), I had to charge the smartphone only after 2 days. The stand-by consumption is also very good due to the really extremely aggressive background management of Color OS. In the PC-Mark battery test, the Oppo Find X lasted for very good 9 hours.Battery lifetime Result Unit: hours
Even if the battery is empty, with the in-house VOOC quick charging technology this is no problem. In only 30 minutes, the phone charges from 10 to 60%. However, with a normal QC adapter you only get 30% per hour. If you want to use Oppo’s Fast Charge, you should possess the right charging adapter. A special edition of the Find X – the Oppo Find X Lamborghini Edition – will also support SuperVOOC, which is even faster. For this test, it has, however, no relevance, the charging time of the Oppo Find X with the included adapter is great and from 0 to 100% it takes 1 hour and 30 minutes.
