At the beginning of March, Oppo presented the successors to that Find X. The Find X2 models have a less daring appearance; they look pretty standard with their three rear cameras and a hole in the screen for the front camera. Although striking technical gadgets are missing this time, Oppo does a lot with the hardware. The Find X2 Pro compares well with Samsung’s Galaxy S20 Ultra. The device has the latest and fastest hardware on board and advanced cameras. The price is also comparable.
Oppo gives its new top model a Pro designation, but the product page is full of Ultra references. The device has an Ultra Vision Screen, an Ultra Vision Camera System and an Ultra Vision Engine. That’s not just marketing talk, because the hardware is certainly impressive, but what about that in practice and can Oppo’s expensive flagship compete with Samsung’s counterpart? We put it to the test and compare the main features of the two top models.
About this article
This is not a full review of the Oppo Find X2 Pro and Samsung Galaxy S20 Ultra. In this article we mainly compare the cameras of the two devices. We also briefly discuss the screen, the battery, the housing and the software. Tweakers will publish an extensive review of the Galaxy S20 series on Saturday.

- Primary camera with new Sony sensor
Manufacturers place a lot of emphasis on the cameras in their most expensive smartphones, and Oppo is no different. The manufacturer has an interesting asset in house with the new Sony IMX689 sensor, which Oppo says it can temporarily use exclusively. It is the largest 48-megapixel sensor for smartphones to date. With its 1 / 1.43 “size, the sensor is slightly smaller than the 1 / 1.33” sensor that Samsung uses in the Galaxy S20 Ultra.
The IMX689 has, according to Oppo, ‘dual native iso’ technology. This means that it has two positions. One is optimized for low iso photos in high ambient light conditions, the other is for low light photos taken at high iso values. Sony has no documentation about this sensor online yet, but inquiring at Oppo teaches us that there is a stand for 64 to 250 iso and a stand for 250 to 19,200 iso. The camera itself chooses the optimal mode, depending on the situation.
Although the Find X2 Pro has a 48-megapixel sensor, standard 12-megapixel photos come from the camera app. Four pixels are combined, which should produce less noise and a wider dynamic range. Samsung’s 108-megapixel sensor does something similar; nine pixels are combined, so the result is also a 12-megapixel photo.

We start with a comparison in good lighting conditions. The phones are in automatic mode on 12-megapixel mode and that’s also how we compare the two devices. The hdr function is also in automatic mode.
Both cameras deliver detailed photos. When you zoom in on the images, the photos from the Oppo sometimes look a bit sharper. It is also clearly visible that the sensor size of the two devices does not deviate much; this is evident from the photo of the bicycle bell. With both the Oppo and the Samsung, such a close-up provides a relatively small depth of field.
There is a big difference in the contrast between the photos from the Find X2 Pro and those from the S20 Ultra. Oppo’s hdr function produces rather faded images because shadows are made too bright. Dark parts are therefore gray. This is particularly noticeable in a lot of light; with the photo of the tree and the sand playground in the twilight, the Samsung phone makes the images exaggeratedly light.
Both phones also have an option to take full resolution photos. The two photos above are an example of this. The Oppo photo consists of 48 megapixels and the Samsung photo has a whopping 108 million pixels. The high resolution results in slightly more detail and the Samsung photo seems sharper, but that’s mainly artificial sharpening that has been added. In general, the high-resolution mode offers little added value and you can better leave the phones in 12-megapixel mode.
Photos in low light
Both the Find X2 Pro and the S20 Ultra have a large sensor, which promises good performance in low light. With its unique dual iso sensor, Oppo has some better papers at home. To see how that works out in practice, we took the photos below after sunset, without using the night mode.
Oppo provides its camera app with a night mode to take photos in low light. It combines images with both slow and fast shutter speeds into a single image. Samsung has a similar night mode.
The first photo, in which the tree was almost completely covered in darkness, looks a bit brighter through the Oppo camera. The Samsung variant is darker and has more noise. In general, it is noticeable that the S20 Ultra leaves more color in the images. You see that especially at the bench; the grass is much paler in the Oppo photo. In this case, you can say that the Oppo night photos are more realistic, because after dark colors are less bright. The photos are comparable in terms of detail and sharpness, but the results of the S20 Ultra have a lot more noise in the air.
Periscopic telephoto lens
Oppo uses a periscopic construction for the telecamera. The lens and sensor are rotated ninety degrees in the housing and the image is received via a prism. That construction is not new to Oppo; the manufacturer also used it in last year’s Oppo Reno 10x Zoom. The Galaxy S20 Ultra also has such a construction, just like the Huawei P30 Pro
According to Oppo, the device has ’10x hybrid zoom’. In practice, it is a telephoto lens with a focal length of 124mm in full-frame equivalent. That is 5x ‘zoom’ compared to the primary camera. If you zoom in further than 5x, the camera uses digital zoom and the image is thus artificially enlarged.
|Telecamera||Oppo Find 2X Pro||Samsung Galaxy S20 Ultra|
|Sensor||Samsung S5K3M5||Sony IMX586|
1 / 3.4 “
|Focal length in 35mm equivalent||125mm||103mm|
|Aperture||f / 3.0||f / 3.5|
|Video||4k @ 30fps||4k @ 30fps|
Oppo uses a Samsung S5K3M5 sensor for the telecamera. That is a small 1 / 3.4 “chip with a 13-megapixel resolution. The sensor surface is a lot smaller than that of the sensor that Samsung uses in the S20 Ultra. In theory, the Samsung device should perform better, especially at little light.
The sensor in the Find X2 Pro is combined with a 15mm f / 3.0 lens with optical image stabilization. The operation of that stabilization mechanism is clearly visible and effective. When taking zoomed photos, you see the image shake first and then stabilize.
The photos below were taken at the 5x zoom position of both devices. The S20 Ultra has to crimp and upscale a bit because the lens offers 4x zoom. We use the 5x mode because Samsung also puts it in its camera app by default; the 4x option can only be found with a small detour. The Oppo and the Samsung are also best compared in this way.
The Find X2 Pro takes sharp, detailed photos in the 5x zoom position. In practice, the larger sensor of the S20 Ultra does not offer any advantage over the smaller sensor in the Oppo. We already noticed that in our previous camera test of the Galaxy S20 Ultra and this comparison confirms that again. The Find X2 Pro’s small sensor delivers photos that are at least as sharp as what comes out of the S20 Ultra.
There are some differences in contrast and color reproduction. In general, the Oppo photos are a bit more yellow and the Samsung photos a bit bluer. The differences are less than with the primary camera and the Oppo photos taken with the telephoto lens are a lot less dull.
In the camera interface, Oppo gives you a choice of 5x and 10x zoom, and you can swipe a virtual zoom wheel to reveal and zoom in even further, up to 60x. Anything beyond 5x will be digitally enlarged at the expense of image quality. We have taken the photos below at the 10x zoom position.
In that mode you can still take useful photos, although the image quality is significantly lower than that of the 5x zoom photos if you view them in large format. Despite the higher resolution of the S20 Ultra, the photos at 10x zoom are not much more detailed than the photos taken by the Oppo in the same mode.
Zooming in even further digitally generally does not provide usable visual material. Samsung even goes up to 100x and puts that on the back of the device, but we concluded earlier that this is nonsensical. In our opinion, the same applies to the Oppo’s 60x zoom photos.
In the gallery above we show the entire ‘zoom range’ of the Find X2 Pro. The first picture was taken with the ultra-wide angle lens, the next two pictures were taken with the primary camera in 1x and 2x modes, and the last three pictures were taken from the telephoto lens set to 5x, 10x and 60x zoom respectively.
Focusing is not possible
The telephoto lens does not allow you to focus on close subjects. Oppo does not say what the minimum focus distance is, but that seems to be about a meter and a half. That is quite disappointing, because with the S20 Ultra you can focus from about half a meter with the telephoto lens.
Oppo doesn’t really make this clear. It tries to disguise this limitation of the telephoto lens by automatically switching the camera to the primary sensor when using the telephoto lens and trying to focus at a short distance. The autofocus does work, but you take a photo with 5x digital zoom with the primary camera, which produces a much less sharp image than if you would use the telephoto lens. You can already see the change in image quality while taking the photo in the camera app.
Moreover, the autofocus of the telephoto lens does not always work well in practice. The camera app uses a fairly large circle to focus, and if you try to focus on a subject smaller than that circle, things sometimes go wrong. For example, in the photos below we tried to focus on the plant in the foreground and on the sign on the pole, but that did not work. Even after pressing repeatedly, the camera refused to focus in the right place. When we zoomed in to 10x in these situations, the autofocus suddenly worked well. Due to the stronger magnification, the subjects took up more space within the focus circle.
Ultra wide angle with large sensor
Many smartphones have an ultra-wide angle camera, but usually manufacturers put a small sensor behind it. Recently we saw that change with the Galaxy S20 Ultra; Samsung has used a 1 / 2.6 “sensor for the ultra-wide angle camera and that produces better images, especially in low light, according to our comparison . Oppo goes one step further and uses the Sony IMX586 as a sensor for the ultra wide-angle camera. That is a 1/2 “48-megapixel sensor used in many smartphones for the primary camera. Samsung uses that sensor for the telecamera.
The angle of view of the ultra-wide angle camera on the Find X2 Pro is a lot smaller than, for example, that on the S20 Ultra. After all, the larger sensor also requires a larger lens and it is difficult to make a lens with an extremely large angle of view that is small and delivers good image quality. The angle of view of the lens used is 120 degrees according to Oppo, but with lens correction switched on, 109 degrees remain.
|Smartphone||Oppo Find X2 Pro||Samsung Galaxy S20 Ultra|
|Camera||Ultra wide angle||Ultra wide angle|
|Sensor||Sony IMX586||Samsung S5K2L7|
1 / 2.6 “
|Focal length in 35mm equivalent||17mm||13mm|
|Angle of view||109 degrees||120 degrees|
|Aperture||f / 2.2||f / 2.2|
Although the Oppo has a 48-megapixel sensor for the ultra-wide-angle camera, the photos have a standard 12-megapixel resolution. The IMX586 sensor has a 2×2 bayer filter, so four pixels are combined for better low-light performance and higher dynamic range. It is possible to choose a 48-megapixel mode in the software. We used the default setting for the comparison.
The first thing to notice is the difference in angle of view. The S20 Ultra can clearly take more pictures. This is useful in small spaces and great for lovers of dramatic perspectives. In a lot of light, there is little difference in sharpness; both phones deliver sharp ultra-wide angle pictures. As with the primary camera, the photos of the Find X2 Pro are somewhat duller, but the difference is less.
In low light, the Find X2 Pro does significantly better than the S20 Ultra. The Oppo’s photos have more detail and less noise. The larger sensor clearly pays off here. It should be said that the S20 Ultra also has a relatively large sensor for the ultra-wide angle camera. Most other smartphones use a much smaller sensor for this; the Find X2 Pro will be even more advantageous.
We also took some ultra wide angle photos in night mode. The phones use slower shutter speeds and combine different images. The photos of the Oppo have less noise, but look a bit more smooth. This is especially visible in the sky. There is also a clear difference in the processing of the colors. The photos of the Find X2 Pro have a green color cast.
Oppo also uses the Find X2 Pro’s ultra-wide angle camera for macro mode. You can focus on subjects three centimeters away. That produces excellent close-ups, which look detailed.
The film function of the Find X2 Pro goes up to 60fps in the 4k resolution, but only when using the primary camera. The same goes for the Galaxy S20 Ultra. With both devices, 4K with 30fps is the maximum achievable when using the ultra-wide angle or telephoto lens. That is disappointing for smartphones in this price range, because with the iPhone 11 Pro it is already possible with all three cameras to film in 4k60fps.
The 4k videos at 60fps look sharp and smooth. At transitions from dark to light, the camera itself adjusts the exposure. Both the Find X2 Pro and the S20 Ultra do not smoothly transition in challenging conditions. You can see that in the change in the exposure of the sky.
Oppo gives the Find X2 Pro a so-called Ultra Steady Video mode. It uses the ultra-wide angle camera and advanced electronic stabilization. The resulting image has an angle of view similar to that of the primary camera. The extra space on the sensor is used to digitally stabilize the image.
Samung offers a similar mode, also using the ultra wide angle camera. Both the Find X2 Pro and the S20 Ultra deliver stable movie images in these modes. You can easily make a video while walking and you hardly see the shocks it produces. Since the ultra wide angle camera is used, the maximum frame rate is 30fps at the 4k resolution.
The images of the Find X2 Pro are sharper in this mode than those of the Samsung. More noise can be seen with the S20 Ultra. The Oppo is clearly at an advantage here with its larger sensor with a higher resolution. The S20 Ultra, with its 12-megapixel sensor for the wide-angle camera, basically has enough pixels for the 4k resolution, but because a crop is made for the electronic image stabilization, more pixels are needed. The Oppo’s 48-megapixel sensor thus pays off in this position.
Screen and battery life
In addition to the cameras, it is mainly the screen with which the top models have to distinguish themselves. Oppo uses a 6.7 “OLED panel with a resolution of 3168×1440 pixels and a refresh rate of 120Hz in the Find X2 Pro. This is comparable to what Samsung offers in the S20 series, but at Oppo the screen can also be used at 120Hz. maximum resolution, which is not yet possible with the S20 models, although Samsung seems to be working on it.The display at 120Hz looks wonderfully smooth and once you get used to it, you probably don’t want to go back to 60Hz.
The main difference between the screens of the Find X2 Pro and the S20 Ultra is in the edges. Oppo uses a screen as we have seen for years at Samsung; with edges that bend quite far over the device, according to the manufacturer with an angle of 67.8 degrees. In its S20 series, Samsung has switched to screens that bend less. What you prefer is a matter of taste. The fact is that with the strong curvature of the Oppo device, more information ‘falls off’ from the image.
We measured the screens with our SpectraCal C6 colorimeter and CalMAN 5 software. The peak brightness of both smartphones is excellent and with more than a thousand square candelas per meter, the best we have seen so far with smartphones.
|Peak brightness white (33% screen area)|

|Apple iPhone 11 Pro Max||859|
|OnePlus 7T Pro||690|
|Oppo Reno2 Z||488|
|Oppo Find X||430|
Oppo says to calibrate the screens of the Find X2 Pro at the factory and our measurements seem to confirm that. The average grayscale error and color error are very low. Never before have we seen such a well-calibrated screen. The S20 Ultra is slightly less accurately adjusted, but in practice that few users will notice.

Battery life and charging speed
Such a large screen with a high resolution requires a lot from the battery. Oppo puts a relatively modest 4260mAh copy in its Find X2 Pro. Samsung’s S20 Ultra is more spacious with a 5000mAh battery.
- Browsing – WiFi
|Battery life for web browsing (brightness @ 250cd / m²)|
|Smartphone||Battery capacity (mAh)||time in hours and minutes (higher is better)|
|Apple iPhone 11 Pro Max||3,969mAh||13h29m|
|Samsung Galaxy S20 Ultra (qhd +, 60Hz)||5,000mAh||13h12m|
|Samsung Galaxy Note 10+||4,300mAh||12h17m|
|Samsung Galaxy S20 Ultra (fhd +, 120Hz)||5,000mAh||11h53m|
|Oppo Reno2 Z||3,900mAh||11h28m|
|OnePlus 7T Pro (60Hz)||4,085mAh||10h5m|
|OnePlus 7T Pro (90Hz)||4,085mAh||9h52m|
|Oppo Find X||3,730mAh||9:26 m|
|Oppo Find X2 Pro (qhd +, 120Hz)||4,260mAh||8am|
With the screen set to the maximum resolution and a refresh rate of 120Hz, the Find X2 Pro is empty after just eight hours of browsing. That battery life can be stretched by choosing a lower resolution or refresh rate, but at the time of writing we do not yet have any test results. The S20 Ultra cannot display 120Hz in combination with the high resolution, so that device will last longer.
The Find X2 Pro’s battery runs out quickly if you use the maximum screen settings, but Oppo does have a strong asset with the SuperVOOC 2 fast charging technology. Charging is no less than 65W and to make that possible, the battery consists of two parts that are charged simultaneously. With Oppo’s charging technology, energy management takes place in the adapter and not in the smartphone. The advantage of this is that the smartphone does not get hot during charging.
hardware and software
The Oppo Find X2 Pro and Samsung Galaxy S20 Ultra are among the largest and heaviest smartphones of the moment. With its curved screen edges and rounded corners, the Oppo is a few millimeters smaller than the Galaxy, but it does not save much. The weight is also comparable; both devices weigh just over two hundred grams. The housing of the S20 Ultra is more angular and bumpier. This is also reflected in the large, rectangular camera island. With the Oppo device, that part is somewhat smaller, but with both devices, the cameras on the back lead to a considerable thickening of the housing. Both the Find X2 Pro and the S20 Ultra are waterproof and dustproof according to the IP68 standard. That is, they survive full immersion.
At first glance, the Find X2 Pro appears to be finished with glass on the back. However, it is a ceramic finish and it has a subtle ribbing pattern. If you slide your finger over the back, you can feel it. You hardly notice that in practice. Certainly not if you have the phone in use and there are some finger marks on the housing. According to Oppo, this structure serves as an anti-slip layer and should also keep fingerprints away. The latter is not really the case; fingerprints are clearly visible on the back. However, you can easily brush them away.
Oppo’s operating system is called ColorOS and the Find X2 Pro has the new version 7.1, which is based on Android 10. The software has a number of useful extras that are not standard in Android. For example, Oppo has added a shortcut menu to the screen edge that you can pull out with a swipe of your thumb with one-handed use. It contains functions such as taking screenshots and opening the file manager. You can adjust the shortcut menu to your liking by using other shortcuts. Also handy is the possibility to place the calculator in a floating window, so that you can use it over other apps.
The Dutch translation in ColorOS is sometimes sloppy. Hyphenation goes wrong and we saw windows in which part of the text was cut out, perhaps because the Dutch words are too long. They are not dramatic errors and do not affect the operation of the device, but in our opinion it detracts from the quality experience. Such flaws do not belong on a telephone of twelve hundred dollors.
