Rejoice, Nokia fans, as the next PureView phone is finally here! The long-rumored Nokia 9 PureView has been unveiled at the MWC in Barcelona and both professional and enthusiast photographers should have something truly unique to talk about.

But before we dive deep into the next PureView camera, let's see what the whole phone is made of.

Well, it's glass, dual-glass to be precise and a metal frame holding those together. We live in the glass smartphones era, so there is little surprise HMD chose to stick with the timeless glass body. The Nokia 9 is also IP67-rated for dust and water resistance.

There is a 5.99" P-OLED display at the front, HDR10-compliant, with a flagship-grade resolution of 2,880 x 1,440 pixels or QHD+. A Gorilla Glass 5 piece keeps that OLED safe from cracks and major scratches.

Nokia has opted for an under-display fingerprint scanner, which is the latest trend, but you can also use AI-driven Face Unlock, if that's your thing.

Oddly, HMD has opted for the Snapdragon 845 chipset for the Nokia 9, which is a bit outdated as the Snapdragon 855 is the current buzzword. Our guess is that since Nokia worked hard for a long time to optimize the camera algorithms, which use all the chip essentials - CPU, GPU, ISP, DSP - it would have been impossible to translate this work for the Snapdragon 855 samples when they became available late last year. Plus, the Nokia 9 PureView isn't thatexpensive, so there is that, too.

The Nokia 9 PureView will be available in only one color - Midnight Blue - and in only one version - 6GB of RAM and 128GB expandable storage.

And now, let's see that new PureView camera.

There are five 12MP cameras on the back, all sitting behind f/1.8 Zeiss lens. Two of those are RGB and the other three are monochrome. There is also a sixth camera here - a ToF one - for additional depth information. A dual-tone LED flash is the final thing you'll see at the back.

Those five camera lenses have the same fixed focal length of 28mm. You won't find an ultra-wide angle or telephoto snappers, and the Nokia 9 doesn't brag with any fancy shooting modes. The PureView was never intended to be the world's most versatile smartphone camera but to deliver brilliant image quality on par with an expensive full-blown camera. So, how does it happen?

The phone combines the images from all five 12MP cameras, sometimes even multiple frames from each of those, into a single image with a spectacular dynamic range - up to 12.4 stops of difference in light which is as much as a large sensor camera. NSo overall, the Nokia Pureview promises unmatched scene depth detection and spectacular dynamic range.

The Nokia 9 was also optimized for those who like to tune their RAW photos in post processing - like opening up shadows, bringing back highlights, and applying just the right amount of sharpening. The developers worked with Adobe to fully support editing RAW data from images taken on the phone. This can be done in the free mobile version of Adobe Lightroom. Interestingly, since Android One is all about a clean slate - Nokia won't even preload the app on the Nokia 9, but it will give you the option to install it during the initial setup.

Nokia has also partnered with Google so that Google's Photos app could natively understand how to support photos taken with the Nokia 9's five cameras. Google Photos will be able to adjust the focal point after taking the photo, adjust the amount of bokeh, and will be able to display the full-size RAW files - which are DNG.

Thanks to the sheer amount of camera sensors and the ToF camera, Nokia says that this setup can produce a depth map for more convincing defocusing gathering up to 1200 layers of depth data (as opposed to only 10 on most phones) for up to 40m away from the camera. This means we should see much more realistic bokeh in photos, the blur would gradually be stronger the further that part of the scene is from the camera. The depth info is stored within the photo and Google Photos will allow you to change the amount of defocusing after the shoot.

The Nokia 9 is smart enough to gauge when it is completely still such as on a tripod and will switch to longer shutter speeds in the dark (up to 10sec). It also supports full manual control, so all professional and enthusiast photographers could tune the settings however they need them.

The video recording part of the camera is not as exciting - up to 4K HDR videos at 30fps.

The Nokia 9 also has a front-facing 20MP f/1.8 camera. It supports Tetracell pixel binning so in low light situations it can combine four adjacent pixels into one producing 5MP images with less noise.

The Nokia 9 will come with Android One (Pie version) out of the box, so you'll know you're going to get quick and timely updates.

Finally, the last bit of the Nokia 9 is the 3,320 mAh battery. It supports fast wired charging (QC3 and USB PD), as well as 10W wireless charging. There is no audio jack on the Nokia 9, though.

Now, let's talk pricing. The Nokia 9 doesn't have the cutting-edge Snapdragon 855, probably because of the complexity of the camera and the long time it took making it, but it seems HMD has taken this into consideration - the Nokia 9 PureView is priced at $699 - noticeably cheaper than the current crop of flagships.

But there is also the fact that the Nokia 9 will have a limited production run. Once the stock is depleted - that's it. Nokia may not be producing any more devices. The company hasn't revealed exactly how many units it will produce, though.

Maybe we will see a Nokia 9.1 with a Snapdragon 855 chip before the year ends, maybe we won't. It would probably depend on the success of this PureView, but it surely shapes to be as the one stop for truly exceptional photos on the go.

Shootout: Nokia 9 PureView gets us closer to the beauty of real bokeh

When we first got wind of the Nokia 9 PureView and its multi-camera system, we were sure Nokia had hopped on the ultra-wide-regular-telephoto bandwagon with a time of flight 3D and monochrome auxiliary cameras to fill the quota up to five. We were wrong.

Nokia surprised just about everyone with the camera selection on the Nokia 9 PureView - five 28mm 12MP f/1.8 snappers, three of which are black and white, two of which are RGB, and a TOF 3D camera on the side. So what do five cameras with identical fields of view do for the one clicking the shutter button?

Nokia has gone for a few inherent advantages of the 9 PureView camera system - great dynamic range thanks to the combination of three monochrome cameras and two color ones, native black and white photography, flexible RAW DNG files to extract the most of the sensors through Lightroom on the phone and superior scene depth mapping with with refocusing possible after the shot.

We think the biggest leap forward might actually be in the quality of the scene depth mapping. You see, having five cameras with different vantage points aimed at the same scene gives the Nokia 9 PureView a highly accurate depth map of said scene. It's not only the resolution of the depth map - there's plenty of phones with high-res imagers. They key is in the levels of depth that can be recognized - Nokia says that while most phones can recognize up to around 10-15 focal planes, the Nokia 9 PureView captures up to 1,200 and through AI extrapolates those into infinite numbers of layers.

This leads to two advantages - the ability to create photos with a realistic defocus effect and the ability to snap a shot and choose a different focus point later (so if you've missed focusing on a person's face it could be fixed, potentially).

Now let's put the Nokia 9 PureView's theoretical abilities to practice. You can see in the image below that compared to the iPhone XS, the Nokia 9 PureView has created a more accurate depth map with improved subject separation from the background. The pointy pines of the pineapple have been blurred out by the iPhone but are preserved on the Nokia image.




This second example stands to show something else - whereas the iPhone was mostly able to separate the plate of croissants from the background, it has blurred out bits of the subject it couldn't correctly place in the focal plane. The Nokia 9 PureView has read the scene more accurately and has produced a gradual blur with more accurate falloff.

The Nokia 9 PureView's shot looks as if taken with a proper camera with a proper lens. The glass plate is blurred in the foreground and background with focus in the middle. In the iPhone image the plate and croissants are both in focus and look as if stamped onto a simulated blur layer.



Both phones produce a depth map and apply software blur to the out of focus areas but the Nokia 9 PureView clearly has a more detailed and accurate depth map. What's curious, you can actually extract the depth map from each image. Here's what the depth map for the images above looks like.


And here's a 3D simulation of a photo taken with all five of the Nokia 9 PureView's cameras we created through Depthy. Most phones will be able to capture a horizontal plane of a scene by using multiple cameras but the Nokia 9 PureView's array allows for both horizontal and vertical information to be captured. Using this 3D plane the Nokia 9 PureView can map a very accurate focal plane.





Keep in mind that most phones do a much better job when simulating potrait mode shots of human faces. There the Nokia 9 PureView won't offer as big an advantage over phones like the iPhone XS or the Samsung Galaxy S10 since the phones are getting a lot better in recognizing faces and defocusing the background behind them.

But this potential for natural-looking bokeh like the one we get from large-sensor cameras is there. We were only able to play around with a pre-release Nokia 9 PureView unit and will go into further testing once we get a retail-ready unit.

As we said, depth-sensing is only one aspect of the Nokia 9 PureView's potential. The pre-production samples we saw a few days ago promise a wide range of possibilities from image stacking and RAW editing.

At the moment the Nokia 9 PureView is unlikely to overtake the best smartphone cameras around. From our early impressions dynamic range isn't on par with the likes of the iPhone XS or the Huawei Mate 20 Pro and the Nokia 9 PureView is noticeably slower to process a photo. But we expect things to improve with time and updates.

For now you can at least expect one of the best bokeh simulations around.

Camera(s) looks awesome. But I can't help but think that it looks like a 2017/2018 phone with that chin and forehead

Nokia 9 PureView fingerprint scanner and UI improved in latest update

The penta camera-toting Nokia 9 PureView has received a new software update that brings in tons of improvements.

This update, bearing version number V4.22C, weighs 250.4MB in size. Its changelog mentions improved system stability, UI enhancements, and April 2019 security patch. However, users report that this update has much more than that.


The new firmware has improved the performance of the phone's in-display fingerprint scanner, but if you don't see any improvements, just try to enroll your fingerprint again and see if it works.

Other enhancements that come along with this build are faster face unlock, accurate screen colors, and better skin tones. The camera takes better photos now, but the image processing speed is still unimpressive.

This update is rolling out over-the-air.
