OPPO Find X3 Pro – practically perfect professional person’s phone (review)


The OPPO Find X3 Pro is its latest flagship iteration – it is a practically perfect professional person’s phone that goes head to head with Samsung’s Galaxy S21 Ultra. It has a few tricks up its sleeve that makes it a very desirable choice.

The OPPO Find X3 Pro has the world’s fastest and latest Qualcomm SD888, a massive 12GB of RAM, a fantastic quad-camera (with 60x microscope), blazingly fast charge, and a 6.7″ 1 billion colour, LPTO OLED screen with superb colour gamut and brightness.

Microscope – from ‘this to this’

Upfront, we will address its single shortcoming – no microSD slot. But then the Samsung Galaxy S21 Ultra and iPhone 12 Pro Max don’t have one either! With full USB-C 3.1 Gen 1 OTG support, it can backup data to an external SSD like our favourite little 38g, 1TB Orico iMatch (9.4/10) at a prodigious rate. Add to that a superb build quality, OPPO’s ‘cameraphone’ focus, a slick-looking flowing glass back, OPPO’s excellent local after-sales service, and it’s a winner.

First impression – OPPO Find X3 Pro

Well, actually, my wife’s impression – small, light with an exciting glass back. The review unit is Gloss Black, but under most light it seems to have a highly polished steel grey look. Its glass back flows like liquid-like over the camera hump with 2x50MP sensors, a 13MP telephoto and a curious 3MP micro-lens (microscope) that you can have fun with.

OPPO Find X3 Pro

The power button has a nice green coloured insert, and the volume keys are on the left. A tiny pinhole selfie camera is top left, and a fast, under-glass, optical fingerprint detector completes the look. It is elegant and desirable rather than edgy. It is a real shame to slip it into the black silicon bumper case provided. As this is a flagship, we will do a full deep-dive review covering over 70 tests and breaking it down into its logical components.

Spoiler Alert – it is a 10/10 offering everything you would expect from a $1699 phone.

What is the Samsung made LTPO OLED.

It is the next premium generation OLED producing higher brightness using less power with more even screen distribution. Similar screens appeared in the Galaxy S20 and S21 Ultra and may be in some of the coming iPhone 13-series.

This screen is part of a unique 10-bit colour path allowing the camera to capture, encode, store, decode, edit, and display all in 1 billion+ colours. It is perfect for professional use and can be Calman calibrated with a choice of gamuts and colour temperatures. Although with a factory-calibrated Delta E of .8, you won’t need this.

The adaptive refresh rate is superb. It knows what the content is and delivers it at the best rate. For example, when screen-on idle, it is 1Hz, for eBooks, it is 5Hz, for movies 24Hz (or whatever the movie metadata requires), 90-120Hz for most games and a fallback to 60Hz. OPPO says this reduces screen power consumption by 50% over a fixed refresh rate.

OPPO has opened its screen API to allow more developers to take advantage of the screen’s capabilities. The key difference between the S21Ultra and OPPO Find X3 Pro – the S21 supports a Samsung stylus.

We stated that the SD888 is the world’s fastest SoC. In the Android world, it is, but the 5nm Samsung Exynos 2100 5G in the Galaxy S21 Ultra beats it in specific tests – mainly Open CL and Vulcan, so it may be a better gaming option.

This device can multi-task, run power and memory hungry apps, and the performance is still silky smooth.

I dislike the trend to combo Accelerometer and Gyroscope LSM6DS0 as it makes the screen rotation sensitivity too touchy and easy. But we won’t take points off because it is now more common on all phones. Wi-Fi performance is exceptional (10/10) with the right router. It holds the signal out to 20m with a solid signal and data throughput. If you use an AC router, you will get a maximum of 866Mbps. BT performance was exceptional to about 35m.

OPPO SuperVOOC 2.0 is one of the safest fast charging methods. The trick is that it uses two 2250mAh series-connected batteries and two charger circuits, so it never stresses the battery. This requires an OPPO charger and cable that delivers 2 x 5V/3.25A circuits equivalent to 10V/6.5A/65W.

OPPO Find X3 Pro battery
That’s right – straight up fast charge

With such charge speed, battery life becomes almost irrelevant. It is at least twice as fast as the S21 Ultra and iPhone 13 Pro Max. You can also use any USB-C PD, PPS or QC charger, but charge times increase.

The BT 5.2 drove our reference Sony WH-1000xM4 in SBC and LDAC modes and provided good clear sound and plenty of volume. We also tested with the M3 version that supports aptX and its variants. There was plenty of volume and an excellent clear feed. USB-C converts to USB-2.0 and a DAC with USB-C earphones. These were excellent. And you will note the SD888 natively supports Qualcomm True Wireless feeds to TWS earphones.

This is a bright vocal signature which is fine for vocals and clear voice. It has Dolby Atmos decoding, but the pre-sets are new to me. It has environmental – indoor, on-the-go, commute and flight. And it has scenario-specific – smart, movie, gaming and music. They don’t appear to make a great difference.

The Galaxy S21 Ultra has better sounding speakers, but the BT and cable sound on OPPO is superior.

* We have to quote OPPO

The back panel of the OPPO Find X3 Pro is a single piece of glass. It has more than 2000 control points to complete the shape, precisely controlling the ultimate balance between the glass’s rigidity and the curved surface’s softness. The ‘Ring Mountain’ image mirror set uses a hot forging glass process rarely seen in industrial mass production. It presents a 3D curved front and back transition and creating a rounded feel. It is a technological breakthrough in industrial design.

Our only comment is that Colour 0S focuses on battery saving over raw power. You can adjust this by allowing frequently used apps to run in the background. Build quality is superb – a Rolls Royce standard.

OPPO Find X3 Pro camera – Dual 50MP combine images

The unique feature is the microscope camera – and it is fun but a lot of hard work to get results. It works up to 3mm away and is more of a scanner (and needs the soft light source) than a camera lens, and builds the image from multiple exposures.

The 50MP IMX766 specifications are currently unavailable, so we don’t know exactly how the dual 50MP lenses work.

We know the dual 50MP sensors uses Quad Bayer binning to 12.5MP and the 1um pixels become equivalent to 2um. Add that to the SD888 triple image signal processor and neural processing unit, and you have exceptional AI computational image capabilities. And this enables image fusing from two or more cameras and DOL HDR (Digital Overlap HDR), which synthesises different exposures into one frame to produce a final result.

Both lenses have colour correction and combine the image in AI post processing

OPPO says that they will be introducing a 50MP Mode without all that post-processing.

With that caveat, here is what we can find.

GadgetGuy’s take

The OPPO Find X3 Pro – practically perfect professional person’s phone.

Apart from the lack of microSD and the annoying combo accelerometer/gyroscope, it is a 10/10 in every way. It is a logical candidate for all flagship LG, Huawei, and Samsung buyers and iPhone fence-sitters. It is easy to swap to OPPO using the Clone Phone app – details here

My daily drive is a Samsung Galaxy S21 Ultra, and both devices have small advantages. For example,

  • S21 Ultra has 100x periscope zoom that I do use, whereas the Find X3 microscope is a little limited
  • 21 Ultra has that 108MP camera that collects so much detail (in that mode). 50MP is not shabby either on the Find X3 Pro.
  • Find X3 Pro photo results are visually more pleasing – not necessarily better. It shows excellent computational AI photography with warmer saturated colours. Samsung is more à la naturel.
  • Find X3 Pro’s 10-bit, 1billion colour screen is amazing and is a draw with te S21 Ultra
  • S21 Ultra has better sound, but it is not a biggie as you almost always use earphones. Find X3 Pro has more BT codecs including the aptX suite.
  • Find X3 Pro has 65W charging – bloody fast. The S21 Ultra has 25W – it takes two to three times as long
  • S21 Ultra can support a stylus and supports cable or wireless DeX desktop on a monitor
  • Warranty and support wise – a draw.

And because there is so little between them, prestige flagship buyers should consider both. I suspect that when you get the lighter and svelter OPPO Find X3 Pro in your hands, you will fall in love and live happily ever after.

And we will be reviewing the Find X3 Neo and Lite. Preliminary details and specs are here, and the Neo is a very acceptable compromise at $1199.


I can’t give it 10/10 as much as I really want to. That is for absolute perfection. But given the comprehensive package and competitive price, it scores 9.8/10. I suspect it will tie with the Galaxy S21 Ultra, so you know you cannot go wrong.
