What does a dual camera do on a phone? Why does a smartphone need two main cameras? What is dual camera

As soon as there were rumors last year that Apple wanted to make a smartphone with two modules at once, manufacturers became seriously alarmed and began to discontinue making two-eyed smartphones.

Some did well, some did poorly, and some were just disgusting. But what are the real advantages of a dual camera? How does it work, what does it give and what is better - a smartphone with one or two modules?

Principle of operation

Works dual camera exactly the same as single. Light passes through the lens and hits the matrix, the processor reads the information from the sensor and converts it into a photo or video.

With dual cameras, everything is the same, only instead of one matrix there are two, which work independently of each other, which means that all processing and stitching of images takes place in the processor and the more advanced it is, the better the quality of the images will be.

For high-quality photos also important software algorithms, and what functions the second module has depends on what the manufacturer provides.

Optical zoom

For example, the second camera in the iPhone 7 Plus is designed for optical zoom. The first module shoots with a wide-angle lens, and the second telephoto lens allows you to take zoomed photos without losing quality.

Previously, zoom in smartphones was mostly digital, that is, the smartphone took a large 16 MP photo and cropped the required fragment programmatically (for example, 2 times) and the resulting photo was no longer 16 MP, but only 8 MP, and accordingly the quality was lost. Now the second module has an optical zoom, that is, a photo enlarged by 2 times is obtained without loss of quality. But not all manufacturers followed this path.

Increased dynamic range

Some people use the second module for other purposes. Like, for example, the dual camera in Huawei P20. It is not designed for zoom, but for magnification. dynamic range and she is not capable of zoom. One module is regular, and the second is monochrome and shoots only in black and white. According to the developers, this gives more detail in the shadows, and the pictures themselves are of better quality, although only a professional can see the difference.

Improved detail

Manufacturers do not always insert the same matrices into both modules. More often, one module is made with fewer megapixels, but at the same time with greater aperture. And the second one with big amount megapixels, but less aperture.

By combining two such photographs you can get a more detailed picture. Because information about colors is taken from the first image, and information about details from the second.

Changing Focus

Also, some manufacturers use a second module to take pictures with variable focus. That is, first you took a photo, and then in the gallery you changed the focus point, if necessary.

And finally, any smartphone with a dual camera can blur the background, or rather create a depth of field effect (bokeh).

In fact, the blur occurs programmatically. The second camera is needed to more accurately determine the object in space. The processor takes two pictures on both cameras, compares them and determines which object you wanted to place in the foreground, after which it applies a filter in real time and blurs the background. In this case, you can often independently set the degree of background blur for the image. This is called program aperture. The wider the aperture is opened, the more the background will be blurred, but most likely more important details will disappear from the image and vice versa.

Software algorithms

When dealing with a dual camera, the software algorithms that process the image are very important. If the algorithms are correct and work without errors, then blur background happens correctly - they are not erased necessary objects, and the edges come out smooth.

On this moment There is no camera that always and accurately determines where the object ends and the background begins.

The best smartphones with dual cameras

Here are a few smartphone models that take better photos with their dual cameras.

OnePlus 5

Xiaomi Mi6

Huawei P20

The photos they produce are of the highest quality. But latest model It’s not worth buying from the list yet, since the firmware is still raw, you need to wait until the fall. The iPhone 7 Plus is also known to blur the background quite well.

Our review included mainly expensive models, there are also cheaper options with two cameras - Doogee Shoot 2, Leagoo M8 Pro.

But you shouldn’t expect high-quality pictures from smartphones costing about $100; they don’t determine the position of the object, but simply “wash out” everything that is possible and impossible.

It is unlikely that you will be able to get a correct photo with such a smartphone. As practice shows budget smartphones with a price of less than $150 they cannot work properly with a dual camera and it’s not worth buying them just for that.

Cost of smartphones with dual cameras

All this is of course good, but how does the presence of a dual module affect the cost of a smartphone? Naturally, there are more components, assembly becomes more complicated, and the manufacturer needs to improve the software in order to adequately use the second module. And all this requires additional costs. However, in fact, devices with a dual camera and a single camera are almost the same in price. So most likely adding additional module has little effect on the cost of the product and the price changes insignificantly.

Do you need a dual camera?

After weighing all the pros and cons, we can say that the presence of a dual camera is more of a plus than a disadvantage. Objectively, if it does not affect the price and brings additional benefits, then why not?

The most adequate option for using a second camera is optical zoom. We are all accustomed to the fact that a smartphone has a fixed viewing angle and in order to enlarge an object without losing quality, we must first approach it. The second telephoto lens solves this problem - I saw a beautiful frame, pressed the button, zoomed in and got nice shot. This is what makes life easier for a mobile photographer.

Plus, if you don't go overboard with the program aperture, you can get great shots, adding an artistic touch to your photos. That is why, when choosing a smartphone today, we prefer a device with two cameras rather than one. Because if you don’t want to, you don’t have to use the second module, but when you need a zoom it will always be at hand.

What to expect in the future

How will the industry develop further, where will the trends go and how will we be able to modify cameras in the future? What other uses for the double module could be found? In our opinion, progress will not stop with just two modules; there are already smartphones with three cameras.

Perhaps four modules with a resolution of 16 megapixels, connected into one conglomerate, will help in the future to obtain high-quality 40-megapixel images. Each camera will take a picture of its own area, after which the processor will “glue” them into one large canvas. Nowadays, smartphones use panoramic mode for this, but taking large pictures is still not so easy.

The first dual camera in phones appeared back in 2007 with the release of the Samsung B710 model, then the resolution of each module was 1.3 MP. Android smartphones first acquired a dual photo module in 2011, these were the HTC Evo 3D and LG Optimus 3D models. In both cases, a duo of cameras was used to capture 3D video that could be viewed on the gadget's screen.

The dual photo module was “reinvented” in 2014 with the release HTC One M8, and after iPhone presentations 7 Plus it has become one of the main trends in the smartphone market. We have made a selection for you, which presents smartphones with dual cameras in different price categories– from branded flagships to budget Chinese devices.

The iPhone 7 Plus uses two photo modules with optical stabilization, 12 MP each. The first of them is equipped with a 56 mm telephoto lens with f/2.8 aperture, the second with a 28 mm f/1.8 wide-angle lens.

This combination performs several functions at once, the main of which is imitation of bokeh (software background blur), which the iPhone does better than all its competitors. In poor lighting, the smartphone always uses a brighter wide-angle module; in addition, it allows you to shoot macro from a minimum distance, while the telephoto lens provides the possibility of double optical zoom, without loss of quality.

iPhone 7 Plus is one of the most powerful smartphones on the market. It runs on an A10 Fusion processor (2.23 GHz), has 3 GB of RAM and 32, 128 or 256 GB of internal memory. The display is presented at an immaculate 5.5’’ IPS matrix with FHD resolution, and a 2900 mAh battery is responsible for autonomous operation. Prices for the younger version of the apple start at 65 thousand rubles

Huawei P9

The dual 12 MP photo module in the Huawei P9 works on a different principle: one matrix is ​​color, the second is monochrome. When shooting, the cameras fire simultaneously, after which the frames are combined into one program. Black and white matrix in in this case provides better detail and an increase in the amount of light captured, which improves the quality of images in low light.

The photos on Huawei P9 turn out really cool, the smartphone can easily compete with market leaders in iPhone face 7 Plus and Galaxy S7. It doesn’t keep up with the rear P9s either in terms of technical specifications; the gadget with a 5.2’’ IPS FHD screen is equipped with a Kirin 955 processor (2.5 GHz), 32/3 or 64/4 GB of memory with a slot for Micro SD and a 3000 mAh battery. Price – from 35 thousand rubles.

Honor 8 is a smartphone with a chic design that inherits the dual camera from the P9. This time the photo module does not have the Leica nameplate, which is why the gadget costs an order of magnitude cheaper, about 25 thousand. However, in all other respects the cameras are extremely similar - 12 MP resolution, dual flash, hybrid laser autofocus. The smartphone takes pictures of excellent quality, detailed and with the widest dynamic range.

Honor 8 was awarded the title of one of the most beautiful devices of 2016, in addition, it has very good specifications. The device operates on the basis Kirin processor 950 (2.3 GHz), has 4 GB of RAM and 32/64 internal memory, expandable. IPS display FHD with a diagonal of 5.2 inches, 3000 mAh battery, front camera – 8 MP.

The ceramic body of Honor 8, which provides a wow effect when looking at the smartphone, is very delicate and does not resist scratches that appear on it after just a few weeks of use without a case. Also among the shortcomings, we note the mediocre quality of video recording; the ability to shoot in 4K is not provided at all.

LG G5

The previous model of the LG G4 smartphone was considered one of best camera phones in its class and remains so at the beginning of 2017, but updated version a top-end device also deserves attention. Korean company once again confirmed the title of the main experimenters in the market and was the first among A-brands to equip its flagship with a dual camera. In addition, the G5 is modular in design and its functionality can be expanded with additional accessories.

LG G5 is equipped with a 2K IPS 5.3" screen, Snapdragon processor 820 (there is also a completely identical SE version with 651 dragons), 32/4 GB of memory and a 2800 mAh battery. The camera resolution is 16 MP (main module with optical stub and f/1.8 aperture) and 8 MP (wide-angle), and there is also laser autofocus, which ensures instant focusing in any conditions.

Among the modules available for the G5 are: a camera control unit (with a shooting button, a focus wheel and an additional battery), an external DAC and a replaceable battery. The advantage of the device is also its price; now the smartphone has dropped significantly in price and costs about 30 thousand. Main disadvantage– low time battery life, however, the G5 will survive the working day.

Smartphones with dual front camera you can count on your fingers the number of devices on the market, and the Vivo X9 is the best of them in terms of all its characteristics. This gadget will definitely please selfie lovers; it is equipped with 20 MP and 8 MP front modules, and can simulate bokeh without worse than iPhone 7Plus. The main camera is also good, its resolution is 16 MP.

Vivo X9 has 5.5'' Super AMOLED An FHD screen, 4 GB of RAM and 64/128 ROM, a 3050 mAh battery and a dedicated AKM4367 DAC, thanks to which the smartphone is head and shoulders above most competitors in terms of sound quality in headphones. Also, the Plus version will soon go on sale, which features an enlarged screen to 5.88”, a Snapdragon 653 processor, a 4000 mAh battery and 6 GB of RAM. The price of smartphones starts from $430.

Redmi Pro is a top-end budget phone from Xiaomi, which uses a dual camera for software blurring of the background. The main module has a resolution of 13 MP, the auxiliary module, designed to determine image depth, is 5 MP, the aperture of both cameras is f/2.0. Distinctive feature Redmi Pro differs from similar smartphones in its ability to simulate bokeh not only in photos, but also when shooting videos.

This smartphone can hardly be called a gaming smartphone, since it is powered by a Helio X20 processor (or X25, depending on the version). In terms of other characteristics, this is a perfectly balanced solution - AMOLED FHD 5.5’’ screen, 3/4 GB of RAM and 32, 65 or 128 GB of internal memory, 4050 mAh battery, and a slot for a flash drive.

However high price on this model(16-22 thousand, depending on the version) puts it on par with the company’s flagship – Xiaomi Mi5, which overall looks like a more attractive solution and, despite the absence of a second photo module, takes pictures of an order of magnitude better quality.

As great alternative Redmi Pro can be considered Le Eco Cool1. This is a relatively inexpensive and productive smartphone with a dual camera, Snapdragon 652 processor, 3/32 GB of memory, IPS screen with FHD resolution with a diagonal of 5.5’’, and a 4060 mAh battery.

The Cool1 uses a dual 13 MP module with f 2.0 aperture, phase detection autofocus and a dual-tone flash. Smartphone extremely high quality pictures, including in poor lighting, and can record video in 4K format.

Among the disadvantages of Cool1, we highlight its specific design with large black frames around the screen. Otherwise it's excellent workhorse, which can be bought for 13 thousand rubles, while Le Eco is officially presented in Russia and you will receive a full warranty from the manufacturer.

Doogee Shoot and Oukitel U20

Rounding out our rating are two inexpensive smartphone from Chinese manufacturers second echelon, which are in many ways similar to each other. Both cost less than $100 and have typical budget features. The differences lie in the battery capacity, the U20 has 200 mAh more, and the cameras - Doogee uses two 13 MP and 8 MP sensors, the latter of which is wide-angle, while Oukitel has 16 MP IMX135 sensors.

Both smartphones are equipped MediaTek processors MT6737T (1.5 GHz), FHD 5.5’’ IPS screens from SHARP, and 16/2 GB of memory expandable with flash cards. This is a good option if you are on a very limited budget, but want to get a decent smartphone that can shoot like a DSLR.

What does a dual camera in a smartphone give us and why in many modern smartphones two cameras, not counting the front one? Surely some buyers are asking this question. More and more new Android smartphones and more are equipped with dual cameras. For those who do not yet know, we will try to explain why this was done.

First, let's define that a dual camera is a camera with two sensors, which is quite obvious. You can see two cameras. In fact, there is one module, but it is double.

About what sensors we're talking about? One of them is usually completely ordinary. As with any other smartphone, this is a camera sensor that is designed to capture color and the highest quality images.

The second sensor serves to capture data that the first one was not intended to receive. The two sensors in the dual camera work completely differently. Various manufacturers smartphones have been invested in dual cameras. The difference lies precisely in the operation of the second sensor.

3D effect

Dual cameras can be used to create the effect of 3D images. Thanks to the second sensor, you can better analyze information about the distance of objects. This makes them almost three-dimensional. Thus, dual cameras are used in Honor 6X and Mate 9 from.

Bokeh effect

Surely you like portrait photos with strong blurred background. We are talking about the so-called Bokeh effect. In the case of a smartphone, such photos can be taken precisely thanks to information from the second sensor.

Augmented Reality

Thanks to an infrared emitter and a second camera with a wide-angle lens, it is possible to study the reflection of light. This helps bring augmented reality into our lives. You can see how this works with Lenovo smartphones Phab 2 Pro and Asus Zenfone AR.

Improved detail

IN Huawei smartphones P9, Mate 9 and Honor 8 from Huawei found another one interesting application double camera. Their camera's second sensor does not capture color information. He sees the world in black and white. But this is what allows him to focus on the details. The first sensor receives the colors, and the second serves to improve the detail of the image.

Shooting in Low Light

Another advantage of dual cameras is that they make it possible to take better photos in poor light. Light is the most important thing in photography. Two sensors capture more details, and they are then illuminated.

Enlargement with minimal loss of quality

Optical zoom is implemented in some smartphones, but not everyone wants to buy them. For the sake of compactness, mobile cameras, as a rule, are not equipped with optical zoom. However, when one of the dual camera sensors is wide-angle, everything changes. The iPhone 7 Plus and LG G5 use dual cameras to give users the ability to zoom in on photos without any noticeable loss of quality. Use it.

Based on materials from Androidpit

In our century, photography technologies have reached unprecedented development, this also applies to mobile cameras, which traditionally have a number of significant restrictions. It is clear that an increase in resolution will not lead to a noticeable improvement in quality; we have not focused only on pixels for a long time. Therefore they appear alternative views shooting - for example, dual camera. Why do you need a dual camera in a smartphone? Let's figure it out.

What can a dual camera do?

What benefits does it provide? mobile camera? Small size apertures, small focal lengths and a physically small sensor do not allow a smartphone to take pictures at the level of larger photographic equipment. To achieve this, smartphone manufacturers use various tricks. In 2017, a dual camera became a popular trend, and almost everyone was equipped with it. flagship smartphone, and great amount more affordable models.

Each company uses the second camera as an auxiliary one, but everyone implements this different ways. Each of the sensors can both capture an image and perform special tasks - for example, the second camera can have an increased focal length or a wider viewing angle. Due to the fact that to improve image quality and viewing angle it would be necessary to increase the size of the sensor, experts came up with the idea of ​​​​using auxiliary sensor lenses in order to obtain the missing parameters. The good news is that both cameras can be used to take a picture at the same time, like eyes - the photos are processed by the processor and a common, more high quality image.
Previously, fashion trends were dictated by the popularity of home 3D, because the dual camera created a three-dimensional image, drawing space in pseudo-3D. And now the dual-camera model is used not so much for stereo photography, but more to improve the detail and contrast of photographs and videos. This mode has a number of advantages, each of which we will analyze in detail.

Dual Camera Features

What’s interesting is that dual cameras are far from an innovation - already in 2011 the first smartphones with dual cameras were presented, although then the second module c tinned exclusively to simulate augmented reality. The very first smartphone with a dual camera was invented by the companyHTC.
There are now many applications for interacting with the camera in augmented reality mode, although now the focus is more on the optional component. Yes, in smartphones Huawei P9 and Huawei P10 the second camera shoots in monochrome mode, and the main one provides color images, and final photography The result is an ideal balance of color and quality. To this day Samsung remains the leader in mobile photography, but for a long time the company did not introduce smartphones with dual cameras, later belatedly picking up the trend.Samsung Galaxy S8 and S9 Plus versions became the first devices with a dual camera from Koreans.
There are also smartphones with a dual front camera, which can be used to take advantage of selfies. However this technology Can also be used to unlock a smartphone using the owner’s face. Stands apart here iPhoneX where an advanced scanner is used FaceID which is much more complex than the IR module, since it uses a neural network component for identification. IN Apple technology The photographic part is traditionally given great attention, for example in iPhone 8 Plus the second camera is used for 2x zoom, which is achieved using optical methods without increasing the focal length or software processing.

Conclusion

Indeed, the second camera provides too many advantages to refuse such a solution. Today such giants have flagships with dual cameras asHTC, Huawei, LG, Apple, Asus, Lenovoand others. We should expect that in the near future there will be flagships with three or four, or even more cameras. Most likely, such smartphones will look like scary insects, but here the principle of more is better, and maybe in the near future companies will come up with a way to disguise the many prying digital eyes.

In February last year, I already blogged about the fact that dual cameras. This is, in fact, what happened (I’m not a leading analyst, if anything, it was just obvious :)). In the end, mobile photography we need to develop it somewhere, simply increasing megapixels is ineffective. And since the physically small size of phone camera sensors and limitations on optics do not allow “turn around,” we have to look for alternative solutions.

Today, HTC, LG, Huawei, Xiaomi, ASUS, ZTE, Lenovo and, of course, Apple have flagships with dual cameras (of course, not only them). Perhaps only Samsung for some reason ignored this trend. Possibly due to technical problems. After all, I recently heard that the early prototype of the Galaxy S8 still had a dual module.

It should be noted that the technology itself is not new. If you remember, in 2010-2011 there was a boom in home 3D. And this affected not only televisions, but also smartphones. The HTC Evo 3D and LG Optimus 3D models were equipped with dual camera modules for shooting 3D video, and their screens displayed glasses-free 3D content. This is a trend on the market even for televisions. And the phones produced a “blind-eyed” image and no one liked it. The dual cameras in them were used only for creating stereo photos and videos. But the benefits of technology are actually greater.

What's good about two main cameras?

Firstly, two cameras expand the “field of view”. If there is only one module, then it is universal - suitable for both landscape photography and macro photography. But the second module can be installed with a wide viewing angle and shoot cool panoramas without “software” gluing.

Secondly, the dual module increases the clarity and contrast of photos. Each camera may shoot slightly differently, emphasizing various details. The two frames are then combined to create the perfect picture.

Thirdly, optical zoom. If desired, it can be installed for one camera module, but this will increase the size of the smartphone, which is not good for the manufacturer. When there are two lenses, one can be wide-angle (captures more in the frame), and the second can be long-angle (sees further). This way you can get 2-3x zoom without compromising image quality.

Well, fourth - beautiful bokeh (background blur). In principle, smartphones with one module can do something similar, but with dual cameras the effect is much better. This is because the first camera focuses on the selected object, and the second effectively blurs the background. Then the pictures are stitched together.

That's all the main advantages of dual modules. However, each manufacturer implements the technology differently, so let's dive into the specifics.

Apple's approach

As you know, only the older iPhone - 7 plus - is gifted with a dual camera. First of all, with this step Apple solved an important problem mobile world- the difficulty of using a full optical zoom. As described above, the second camera has a long focal length lens and, compared to the first, provides zoom without digital zoom. Everything works very clearly, thanks to the software.

The fact that the two cameras have different focal lengths also benefits from the option of shooting portraits. Again, I already wrote about this “feature” above - images from two cameras are combined, as a result, the object being photographed is as clear as possible, and the background is artistically blurred. Maybe sometimes the effect seems too “artificial”, but still the two cameras implement it much better than purely software solutions.

Apple also has imitators. New model ASUS Zenfone 3 Zoom (introduced earlier this year) also has a dual camera. And unlike its predecessor ZenFone Zoom(it used a system of several lenses) gives a 2x zoom purely due to different focal lengths. The model also supports shooting side-by-side portraits, and also features super-fast phase detection autofocus.

LG

Long before the seventh iPhone was released, it was introduced modular flagship LG G5 with dual camera. True, few people will even remember this fact, since the phone was almost never seen on the market. They tried to make the G6 completely different, but it still has two main cameras.

It's interesting that LG uses dual-camera technology differently than other manufacturers. The second lens here is not long-focus, but rather wide-angle - with a viewing angle of as much as 125 degrees. There is no analogue to optical zoom, but you can shoot gorgeous panoramas - A LOT fits into the frame! True, the edges may be “blurred”, but this is not critical for everyone.

Huawei

This brand was one of the first to “revive” the dual camera in a smartphone. The Honor 6 Plus model went on sale at the beginning of 2015. Since then, Huawei flagships have always come out with dual modules. Including the popular P9 and the newest P10. And here there is very interesting feature: One camera captures exclusively monochrome images. This means that she is picking up more light, provides better sharpness, and also shoots perfectly in low light conditions. As a result, the image from two cameras is combined into a high-quality picture.

“Side” plus - you can shoot black and white photos V excellent quality(that is, better than the usual programmatically “bleached” ones).

However, Huawei is not the only one using this technology. Last fall, hardware giant Qualcomm announced the Clear Sight platform, another embodiment of the same idea with monochrome photos. The cameras are supplied in a ready-made “chip”; any smartphone manufacturer can easily use it. In particular, Xiaomi Mi 5s Plus boasts Clear Sight technology.

The past, present and future of dual cameras

As mentioned in the introduction, the current boom in dual cameras is not the first of its kind. Once upon a time, the Koreans were pioneers in terms of technology - back in 2007 it was introduced Samsung model SCH-B710 for domestic market. It was equipped with two cameras (1 MP each), and the display could reproduce stereo images. Apparently popular phone I didn’t, since there was no continuation.

In 2011, the tri-dash LG Optimus 3D Max and HTC Evo 3D were sold. Niche models hardly attracted the attention of buyers. And since the two main cameras were used exclusively for shooting 3D, which did not become popular, they did not develop the idea.

IN 2014 year HTC In a vain attempt to regain interest in my products, I again remembered the technology of two cameras. The flagship HTC One M8 was equipped with a main and secondary camera (4 MP UltraPixel + 2 MP). The second was only suitable for blurring the background. And this was done optionally - after shooting in the gallery.

The same technology was then used by ZTE in the Axon series and the Grand X Max 2 phablet, and Xiaomi in Redmi Pro. Plus several more Chinese manufacturers. It is still relevant today. Huawei has a similar implementation of “dual-chamber” in a budget Honor models 6X. One module is a full-fledged 12-megapixel, the second is an auxiliary 2-megapixel (useful only for “bokeh”, but still an interesting “feature” to stand out among competitors).

Sometimes two cameras are installed on the front panel of the smartphone. The “zoom” function is relevant here - you can take regular and group selfies without difficulty. This implementation is found in LG V10/V20, Vivo X9.

The current flagships have already been mentioned above - iPhone 7+, LG G6, Huawei P9/P10.

What does the future hold for dual cameras? Interesting technology introduced earlier this year oppo company. It's called 5X Precision Optical Zoom - as you can easily understand, we're talking about 5x optical zoom. It also uses two photo sensors, but there are no two lenses on the smartphone body. One of the sensors is hidden inside the body; a movable lens system is used, located at an angle of 90 degrees. Thanks to this, it is possible to maintain the extremely thin body of the smartphone. In general, the design resembles a periscope (light reaches the sensor through a special prism and a glass window).

Of course, with such a magnification, any hand shake will blur the frame. Therefore, OPPO also developed an advanced system optical stabilization for both the photosensor and the prism: correction is carried out in increments of 0.0025 degrees. Smartphones supporting OPPO superzoom have not yet been released, we are waiting.

Another technology that uses multiple cameras in smartphones was developed in the depths of the project Google Tango. We're talking augmented reality here. True, more cameras are required - three or more. And all of them are used to collect information about what is happening around and model virtual reality. By the way, smartphones on the Tango platform already exist, for example, Asus ZenFone AR. I think the idea may well take off, and it’s not for nothing that Google is working on it.

In any case, the use of multiple main cameras in smartphones is an interesting and promising topic. Do you also think so? Would you like a smartphone with a dual camera? Or is it all pampering?..
