Mobile phones with a double camera. Why the smartphone is two main chambers

Not so long ago, Sony made a rather bold statement. According to the company, in 2017, flagship smartphones for the production of which Sony took. You probably heard that the iPhone 7 Plus is likely to get a double chamber. He will not be the first. Many flagship smartphones are already pleasing to users with a double chamber.

We will not remember the LG Optimus 3D and HTC EVO 3D, which several years ago tried to surprise the owners of these smartphones 3D photos. It was an unsuccessful idea. Only after time, the manufacturers were able to find the use of a double camera module. Where is it already used? In these smartphones:

HTC One. M8.

The second camera in this HTC allows users to change the focal length on the picture already taken. It is noteworthy that already in the next generation of flagship hTC Smartphones The second camera disappeared.

Honor 6 Plus.

In Huawei, a double camera found a completely different application. Two sensors allow a smartphone camera to get more light and take better quality pictures with low lighting. By smartphone from two photos from 8 megapixel chambers makes one 13 megapixel photo.

Qiku Q Terra

Two 13 megapixel sensors of this little-known Chinese smartphone also allow you to shoot high-quality photos with poor lighting.

Lenovo vibe. S1.

In that chinese smartphone Two frontal chambers intended for selfie. The 8-megapixel front camera assumes the entire main job, while an additional 2 megapixel camera is used to estimate the distance, as in HTC One M8.

This smartphone will offer you to shoot Selfie in the company or one. In order for all your company to get into the picture, the smartphone was equipped with a widescreen 8 megapixel camera. The 5-megapixel camera is suitable for photos of the owner alone.

All the same suggests the novelty from LG, but this time is not a frontal, but about the main chambers. There is also a mode that allows for one snapshot to use a widescreen and conventional chamber.

According to Phonearena

The first double camera in the phones appeared back in 2007 with exit samsung Models B710, then the resolution of each module was 1.3 MP. Android smartphones first acquired a double photo model in 2011, these were HTC Evo 3D and LG Optimus 3D. In both cases, the duet cameras were used to feature 3D video, which could be viewed on the gadget screen.

Double photo module "invented re-" in 2014 with the yield of HTC One M8, and after the presentation of the iPhone 7 Plus, it became one of the main trends in the smartphone market. We made a selection for you, which presents smartphones with a double camera in different price categories - from brand flagships to budget Chinese devices.

The iPhone 7 Plus uses two photo models with optical stabilization, 12 megapixel each. The first of them is equipped with a 56 mm telephoto lens with a light f / 2.8 light, and a second-rolled lens 28 mm F / 1.8.

Such a combination performs several functions at once, the main of which is imitation bokeh (rear background software), with which iPhone copes better than all competitors. With poor lighting, the smartphone always uses a lighter wide-angle module, in addition, it allows you to shoot macro with a minimum distance, the body-lens provides the ability to double optical zoom, without loss of quality.

iPhone 7 Plus is one of the most productive smartphones on the market. It works on the A10 Fusion processor (2.23 GHz), has on board 3 GB of RAM and 32, 128 or 256 GB of integrated memory. The display is represented by impeccable 5.5 '' IPS matrix with FHD resolution, and for the autonomous operation corresponds to a battery with a capacity of 2900 mAh. Prices for the younger version of the apple begin with 65 thousand rubles

Huawei P9.

A double photo module at 12 meters in Huawei P9 works on a different principle: one matrix is \u200b\u200bcolor here, the second is monochrome. When shooting cameras, it is triggered at the same time, after which the program works are combined into one. The black and white matrix in this case provides better detailing and an increase in the amount of captured light, which raises the quality of the pictures with poor lighting.

Photos on Huawei P9 are really cool, the smartphone may well compete with market leaders in the face of iPhone 7 Plus and Galaxy S7. It does not graze the rear P9 and according to the technical characteristics, the gadget with the 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 micro SD slot and an acb per 3000 mAh. Price - from 35 thousand rubles.

Honor 8 is a smartphone with a chic design that inherited a double chamber from P9. A photo module this time without a namedhouse Leica, which is why the gadget is an order of magnitude cheaper, about 25 thousand. However, in the rest of the camera, it is extremely similar - a resolution of 12 meters, a double flash, a 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, and it also has very good technical specifications. The device operates on the basis of the KIRIN 950 processor (2.3 GHz), has 4 GB of RAM and 32/64 built-in memory with the possibility of expansion. IPS FHD display with a diagonal of 5.2 inches, a battery for 3000 mAh, front-line - 8 megapixel.

The Ceramic Horus Honor 8, providing the Wow effect when looking at the smartphone, is very gentle and poorly opposed to scratches that appear on it after a few weeks of use without a cover. Also among the disadvantages, we note the mediocre quality of video recording, the possibility of shooting in 4k is not provided at all.

LG G5.

The previous model of the LG G4 smartphone was considered one of the best camerafones in its class and remains as at the beginning of the 2017th year, but the updated version of the top device also deserves attention. The Korean company once again confirmed the title of main experimenters on the market and the first among A-brands equipped its flagship with a double camera. In addition, G5 has a modular design, and its functionality can be expanded with additional accessories.

LG G5 is equipped with a 2K IPS 5.3 "screen, SNAPDRAGON 820 processor (there is also a fully identical version of SE with 651 dragon), 32/4 GB of memory and 2,200 mAh. The resolution of the chambers is 16 megapixels (the main module with an optical stab and light f / 1.8) and 8 MP (wide-angle), there is also a laser autofocus that provides instant focusing in any conditions.

The difference in the seizure of the usual and wide-ancient

Among the modules to the G5 are available: a chamber control unit (with a shooting button, focus wheel and an additional battery), an external DAC and a replaceable battery. The advantage of the apparatus is its price, now the smartphone has cheaper significantly and costs about 30 thousand. The main drawback is low time autonomous workHowever, the working day G5 will live.

Smartphones with double frontal chamber On the market you can recalculate on your fingers, and Vivo X9 for the totality of characteristics is the best of them. This gadget will definitely delight selfie lovers, it is equipped with frontal modules by 20 megapixel and 8 megapixel, and can imitate bokeh worse iPhone 7 plus. The main chamber is also good, its resolution is 16 megapixel.

Vivo X9 has 5.5 '' Super AMOLED FHD screen, 4 GB RAM and 64/128 ROM, AKB for 3050 mAh and highlighted ACM4367 DAC, thanks to which the smartphone stands down the majority of competitors in the quality of sound in headphones. Also on sale will come soon plus versionwhich is characterized by an increased 5.88 '' screen, the Snapdragon 653 processor, 4000 mAh battery and the presence of 6 GB of RAM. The price of smartphones starts from 430 dollars.

Redmi Pro is a top stateright from Xiaomi, a double camera in which is used for software blur back background. The main module has a resolution of 13 megapixel, auxiliary, designed to determine the depth of the image - 5 MP, lights up both chamber is F / 2.0. A distinctive feature of Redmi Pro from similar smartphones is the ability to imitate bokeh not only in the photo, but also when shooting video.

This smartphone is difficult to name game, as it works on the basis processor Helio. X20 (or x25, depending on the version). For 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, the presence of a slot for a flash drive.

but high price on the this model (16-22 thousand, depending on the version) puts it in one row with the flagship of the company - Xiaomi Mi5, which as a whole looks like a more attractive solution and, despite the absence of a second photo module, removes an order of magnitude better.

As excellent alternative Redmi Pro can be viewed by Le Eco Cool1. This is a relatively inexpensive and productive smartphone with a double chamber, the Snapdragon 652 processor, 3/32 GB of memory, the IPS screen with FHD resolution with a diagonal of 5.5 '', and 4060 mAh battery.

Cool1 uses a double module for 13 megapixel with a luminosity of F 2.0, a phase autofocus and two-ton flash. Smartphone is extremely high-quality pictures, including with poor lighting, and knows how to record video in 4K format.

Among the flaws of Cool1 will highlight a specific design with large black frames around the screen. In all the rest, this is an excellent workhorse, which can be bought for 13 thousand rubles, while Le Eco is officially represented in Russia and you will receive a full-fledged guarantee from the manufacturer.

Doogee Shoot and Oukitel U20

Closure our rating two inexpensive smartphones from chinese manufacturers The second echelon, which are largely similar to each other. Both are cheaper than $ 100, and according to characteristics are typical state employees. The differences are in the battery capacity, the U20 is more than 200 mAh, and the cameras - in DooGee, two sensors are used on 13 MP and 8 MP, the last of which is wide-angle, and the IMX135 sensors are installed in OUKITEL.

Both smartphones are equipped with MediaTek MT6737T (1.5 GHz) processors, FHD 5.5 '' IPS screens from Sharp, and 16/2 GB of memory with the ability to expand flash cards. This is a good option, if you are very limited in the budget, but you want to get a decent smartphone capable of shooting by imitating the mirror.

Double camera is the 2016 trend in smartphone-building, although the first attempts to place the rear mobile device Two modules for the photo, were taken much earlier. Considering that the dual camera is equipped with an iPhone 7 Plus, while others (especially the Chinese) love to imitate Apple - the tradition to equip their braes in a couple of cameras continues in 2017. Why do you try to figure out the smartphone.

One of the ways to use a double camera - shooting stereo intended for viewing on a 3D monitor. To do this, the smartphone is equipped with a pair of modules located on a short distance Friend from each other. The lens of each of them has a little different field of view, just as the left eye sees everything from a little different angle than the right. Due to the separation of pictures from cameras (usually anaglyph, with the help of red and blue light filters) - when using special glasses, such photos seem volumetric, three-dimensional.

The first smartphones with a double 3D camera were LG Optimus 3D Max and HTC Evo 3D. However, the technology is not devoid of deficiencies, first of all, due to the fact that the distance between lenses differs from the distance between the eyes. Smartphones with cameras shooting in stereo-format have not become popular.

Expansion of field of view

The second way to use the double module in the smartphone is the expansion of the field of view of the lens. The custom (universal) optics is designed for shooting both in macro and landscapes. Because of this, its overview angle is pretty limited: so that everything falls into focus, you will have to use strongly curved lenses with the effect of fish eye, or do non-standard widescreen photosensors (for example, with a 2: 1 proportions). An additional module equipped with the most suitable for photos of landscapes and panoramas components saves the situation.

An example of a smartphone in which the second camera is used to shoot panoramas and landscapes - LG G5. In such gadgets, the main matrix is \u200b\u200buniversal, and has an angles of view 70-90 degrees. The second is more narrowly specialized, with an extended up to 100-120 or more degrees of the field of view. This allows you to make panoramas in one instant, without the use of gluing and movement of the smartphone, inevitably leading to the occurrence of graphic defects in the picture.

Optical approximation

One of the shortcomings of smartphone cameras is the absence of an optical zoom. When the object of the shooting object is approaching, the system simply takes a piece of the image and "stretches" it to the desired size, but the detailing from this does not improve. To embed a full-fledged zoom mechanism was tried back in 2005-2006 (for example, in Nokia N93). However, it is complicated, is large (to make sure it is enough to look at the "soapms" with a telescopic lens) and roads, therefore does not fit. But if you just put two identical chambers, one of which has standard optics, and the second telescopic, then switching between modules - you can bring closer object.

A double module used for optical zoom has Apple iPhone. 7 plus. Both matrices in it are the same, but one is equipped with high-sound optics with standard parameters, and the second with a limited viewing angle, but with a long overview.

Optical approximation in iPhone 7 Plus

Raising clarity, detail and contrast photo

The digital camera best transmits the object on which focusing was performed. Side parts will be transmitted less qualitatively. Considering that two cameras and lights will catch more, and can focus on different points Regardless, they will be able to provide a clearer transmission of parts. Two photos connected on the principle of HDR together, combine the advantages of both cameras. For example, if one focuses on the bright summer sky, and the second - on the items in the shade, then in the frame and the sky will be the same bright, and the shaded objects will not be in the dark.

The use of a double module with cameras, one of which is color, and the second is monochrome (like Huawei), increases clarity and detail. The black and white sensor does not need a clear gender transmission (it transmits it simply one of the grayscale grades), so that it "focuses" on the contours, and not color. It is for this reason that night surveillance cameras make monochrome. Color matrix is \u200b\u200bengaged in color fixation, black and white - better registers small details, and together - they give both a bright, and detailed picture.

Focus on the shooting object, bokeh effect

The chicken of the near-plane lenses used in conjunction with professional cameras (mirrids, mirrors) is the natural "bokeh effect" - the background is bleated, with the extraordinary clarity of objects in focus. The universal lens (which is equipped with a matrix of the average smartphone) so can in principle - the optical parameters are not those. But if you make two modules, one of which will focus on the subject of the shooting, and the second will fix what needs to be closed - the gluing frames with them will make it possible to achieve proper effect. This blur is achieved by the programmate. The reference in shooting frames with the bokeh effect is considered to be the iPhone 7 Plus. Example of the "bokeh" effect aid iPhone 7 Plus:

For the side of the bokeh and detail of the subject, the double matrix is \u200b\u200bused yet in smartphones Xiaomi. (MI5S Plus, Redmi Pro). It is not always very successful, but on average - the effect turns out a little better than using purely software methods of blurring the background environment.

Other effects

There are other goals for which a double camera in the smartphone can be used, but they are not so common. For example, in Xiaomi with a double matrix, you can take a photo with a changeable focus, but this possibility is actually a derivative of the already mentioned fracture function. You can also make two cameras with different fields of view, from the pictures of which a seamless wide-angle panorama will be brought, but this function is also not in demand yet. In principle, you can use a double module in many ways, everything is limited only by fantasies of developers. So in 2017 we can expect new applications.

18.05.2018

Times, when people rejoiced one camera in the phone, have long passed. Modern smartphones They are taken with lenses as Asian tourists, depending on the manufacturer and the cost of them you can detect one or two frontal and as much, or even three, the main module. What is this - marketing trick or actually working? We understand the details.

History of the question

His history double cameras in smartphones began in 2011 with the advent of HTC EVO 3D and LG Optimus 3D. True, their implementation in the root differed from modern solutions - two modules were used to create 3D images that can be viewed without special glasses. In reality, photography were similar to Soviet double cards with a varied picture of the picture. Completely expected gadgets fell on sale - users did not like the pseudo 3D effect. By the way, the TVs with this technology also did not fit, now they have practically disappeared from the sale.

However, HTC did not abandon the idea of \u200b\u200btwo-chamber gadgets and in 2014 released HTC One M8. Perhaps it was the first mass apparatus with two modules. Auxiliary lens was used to collect information about the depth of the scene - it is necessary for the possibility of changing the point of focus on the frame after the photo was taken. It can be said that the technologies underlying One M8 were the progenitors of the portrait mode in most modern smartphones.

Experiments in this direction continued to Huawei, releaseing Honor 6 Plus in 2015. The flagship apparatus has received two main 8 megapixel chambers. The second module was also used to blur the rear background, as in HTC. The technology was still raw and algorithms often missed - blurred hair, hands and other parts of the body.

2016 has become a turning point for dual modules. At first, Huawei released a number of flagships with a double camera (Huawei P9, Huawei P9 Plus, Honor 8, Honor V8), then LG (G5), but I secured the success of the technology apple company With your iPhone 7 plus. Moreover, these three companies have three absolutely different implementation of the use of auxiliary module. We will tell about them in more detail.

Black and white module

As a rule, the Black and White Module as a second chamber uses Huawei in its flagships. Although sometimes other manufacturers use it - for example, the Nokia 8 and Essential Phone boast.

In its first generation this technology He was a bundle of two modules - a color, designed for the usual shooting and monochrome. The automation instantly takes pictures from both cameras and combines them, at the output, giving out frames with a wide dynamic range and excellent color reproduction. In addition, the second lens helps more accurately measure the depth of field, which allows you to make beautiful portrait pictures with a blurred background. For example, such a two-chamber is implemented in Honor 8 and Nokia 8.

In 2017, Huawei went further and implemented a more advanced camera with a 20 megapixel monochrome module. He also worked simultaneously in the bundle with the main color module and allowed to twist the back background. In addition, the monochrome module received a new opportunity - the hybrid zoom. Thanks to him, you can use a two-time approximation without loss of quality. It is implemented thanks to the cunning work. smart algorithm In the chamber, which makes crop from the camera by 20 megapixel. Such modules are in Huawei P20, Honor 9 and Honor View 10.

Telephoto lens

Apple went on his way. Instead of a black and white module, she put an auxiliary telephoto lens in the iPhone 7 plus. Its focal length is immediately configured to a two-time optical approximation without loss of quality. When necessary, the user simply presses the zoom button and the camera instantly switches.

The side effect of this approach was the portrait mode. It works like this: Images from two cameras are combined into one, and a person or subject in the foreground becomes the only fragment of the photo on which focus is concentrated. Although this effect is somewhat artificial, it is still implemented better than software solutions This task.

Module for blurring rear background

In most smartphones of the budget and middle segment with a double chamber, black and white modules, telephoto lenses or wide-angle are not put. That would make them noticeably more.

As a rule, in the available gadgets, a simple auxiliary sensor is used only for a beautiful blur of the rear background - yes, by the same technology that was used in HTC One M8 2015. However, now the algorithms have become smarter and most modern devices make very good portrait pictures with a minimum number of marriage.

From inexpensive devices double chamber equipped with Honor 9 Lite, Huawei Y9 2018, Alcatel 3X.

What's next?

The future of cameras showed Huawei. In 2018, she presented the flagship P20 Pro with a triple camera. The smartphone has a lens with a three-time optical zoom, the main color module and the third is monochrome. As a result, it gives a fivefold hybrid zoom at once without loss of quality.

Thanks to the zoom and incredible night shooting, Huawei P20 Pro cameras were virtually unanimously recognized as the best camera in 2018. Probably, other manufacturers will also go along the path of the Chinese giant, adding another module for shooting.

Eventually

Double camera - It is a significant plus to the quality of photos from a smartphone opening additional features For creativity, whether it is a photo for social networks Or pictures for a personal archive. Various systems Cameras will help choose a device for their own tasks.

You do not need to consider smartphones with a double camera with something too expensive. To date, the price of such devices begins from 9990 rubles, it all depends on the desired technical characteristics. In a thoughtful approach to the choice, everyone can find a gadget for his pocket. For example, Alcatel 3X.

The iPhone 7 Plus uses two cameras with a resolution of 12 megapixel. One module wide-angle, it allows you to capture more light and make high-quality pictures even in low light conditions, and the second is telescopic, thanks to which a two-time optical zoom is implemented. So you can shoot larger plans and use the approach without loss of quality if the object is in the distance.

In the smartphone, portrait mode is also used, allowing you to leave the forefront in the focus, and wash the background. As a result, it turns out beautiful and expressive portrait photos, comparable to the quality of mirror cameras.

In addition to two cameras, the iPhone 7 Plus is equipped with a 5.5-inch screen with a Full HD resolution, the most powerful Apple A10 Fusion processor and stereo speakers. All this is concluded in a thin metal case, protected from water and dust according to IP67.

OS: iOS 10. Processor: Apple A10. RAM: 3 GB

Huawei P10

Huawei is one of the first to launch smartphones with two cameras, promoting this feature as a key. Last year, a very successful P9 was released, his successor was available in 2017 - Huawei P10.

In a novelty, two chamber modules developed in conjunction with the German company Leica. The first color module for 12 meters, the second is monochrome with a resolution of 20 megapixel. The automation instantly combines pictures from two cameras, gives out beautiful frames with a wide dynamic range and excellent color reproduction.

Two-chamber is used and for the bokeh effect - a beautiful blur of the rear background. Another device knows how to shoot remote objects without loss of quality - this uses a 2-fold hybrid zoom. They did not forget about the optical stabilization that does not allow to make a lubricated snapshot even with poor lighting.

The remaining features are such - 5.1-inch display with Full HD-resolution, 4 GB of operational and 32 GB of integrated memory, an extensible memory card, an eight-core processor KIRIN 960 and a battery capacity of 3200 mAh supporting the function fast charging By branded technology Huawei Supercharge.

Honor 8.

Another smartphone company with two cameras. Both modules have a resolution of 12 MP. One lens takes a black and white image, and the other is color. Then both frames are almost instantly combined. It is necessary to expand the dynamic range - the ability to maintain parts in the darkest and light sections of the frame.

To blur the rear background in the chamber uses a wide diaphragm mode. With this feature, you can manually configure the depth of field while shooting or after the frame is made.

In addition, when editing photos, you can change the focus points by setting the necessary object to the fore. In general, the camera in Honor 8 gives ample opportunities for creativity to its owner.

And Honor 8 boasts a beautiful glass case and a large number of color solutions - blue, black, white, pink and gold. For the work of the smartphone answers powerful processor KIRIN 950 and 4 GB random access memory. Two options are available to the choice - with 32 or 64 GB of internal storage. Battery capacity 3000 mAh, and the screen is a 5.2-inch IPS matrix with Full HD-resolution.

Xiaomi Mi5s Plus.

Xiaomi Mi5s Plus is equipped with a double base chamber with a resolution of 13 MP + 13 megapixel. One module makes a color snapshot, and the second is monochrome. The main feature of the camera is that two modules do not work together by default - for this you need to activate a special stereoor, selecting the icon with a diaphragm on the display.

The camera in this mode becomes noticeably slower, but allows you to get pictures with a wider dynamic range and better working out of parts in the dark.

Characteristics of the smartphone are 5.7-inch Full HD screen, processor Qualcomm Snapdragon. 821, 4 GB "RAM", 64 GB of internal memory and battery with a capacity of 3800 mAh. As a result, we get a big flagship at an attractive price.

LG G5 SE

LG also uses two cameras in many of their smartphones, but their functionality is radically different from what other manufacturers use. The main G5 SE module has a resolution of 16 MP, the second is a wide-angle 8 megapixel module with an angle of shooting 135 °.

A separate wide-angle lens, on the idea of \u200b\u200bthe creators, should help photograph panoramic landscapes, high buildings or groups of people without having to retrieve a large distance from the shooting object.

Switching modes occurs instantly, there are two corresponding buttons in the camera interface. How to show research by LG, users this smartphone Use wide-angle shooting in 55% of cases - this indicates that the function is very in demand.

LG G5 SE equipped with a 5.3-inch screen with a resolution of 2560x1440 pixels and the Always ON DISPLAY function, the Qualcomm Snapdragon 652 processor, as well as 3 GB of operational and 32 GB of integrated memory, 2,200 mAh battery.

In addition, the smartphone is made according to a unique modular system. Instead of a removable bottom panel, you can put various branded modules. For example, a handle with an additional battery and a camera control buttons or a module with a digital-analog converter for music alphas, developed in conjunction with the Danish company Bang & Olufsen.

ASUS ZENFONE 3 ZOOM ZE553KL

Asus introduced Zenfone 3 Zoom at the CES 2017 exhibition and now you can buy it in Russia. The main feature Smartphone has become a double camera module.

The main one has a wide-angle lens with a large aperture (F / 1.7) and a matrix of 12 MP with support for ASUS Superpixel technology. It is designed to shoot everyday scenes, including low light.

The second camera - with the same resolution of 12 MP and an optical increase of 2.3 times - serves to obtain high-quality images close-up. That is, a key "chip" of the device was the 2.3-fold optical zoom, which allows you to use the approach without loss of quality.

The camera is not the only dignity ASUS Zenfone 3 zoom. The newly installed battery with a capacity of 5000 mAh - should be enough for a couple of days of active work.

The Qualcomm Snapdragon 625 processor and 4 GB of RAM, which is enough to start all modern games without freezing, is responsible for the work of the smartphone. 64 GB of memory is provided for storage, and the screen size is 5.5 inches. And all this at a very attractive price.

ZTE Blade V8.

Phab 2 Pro is the world's first smartphone with Tango technology - Google technology, which allows the use of augmented reality (AR) in games and applications. In the gadget, not even two, but three modules located on the back - the main 16-megapixel camera, the depth camera and the tracking chamber of movements.

Thanks to the above cameras, sensors and developed software The phone is able to create a 3D-model of the room in which it is located. That is, the device can track movement, investigate the environment and perceive the depth of space. These data are subsequently used in order to impose a virtual picture on the image of the real world, which is displayed on the phone screen.

At the moment it is an experimental function, but now it works fine and is practically not mistaken. But there is also a problem - for this technology, there are practically no software. You will have to be content with multiple applications and a pair of games.

Lenovo Phab 2 Pro got good components. The device runs on the Qualcomm Snapdragon 652 processor with a clock frequency of 1.8 GHz. Also, the Chinese installed 4 GB of RAM and 64 GB internal memory (Naturally, it can be expanded). In addition, under the 6.4-inch Quad-HD display settled lithium-ion battery at 4050 mAh.
