When the number of various sensors and exotic “chips” in Korean smartphones beginning to scare away customers, Samsung has released an experimental Galaxy Alpha, which gave way to a powerful stuffing quality metal casing. Suddenly it became clear that judges “faceted” design among buyers Galaxy no less than athletes who rush with smiles in the rain (using water resistance IP67 in) guns on a curved display applications for measuring heart rate, and during a break soulfully record their impressions with the stylus, while retaining the image using gestures in the air.
The success of the smartphone Galaxy Alpha gave the green light branding «A-Series”, which made it a goal to attach to the Samsung smartphone buyers, which features an abundance of flagship Galaxy S still just frightened. For the purpose of delimitation of new smartphones with established flagship Samsung has given the new models are more modest performance. On the example of the older models in the lineup, Galaxy A7, we will find out whether or not to annoy the owners of the smartphone hardware limitations of the model, and whether «Galaxy without the bells and whistles” to compete with other brands for which metal body has ceased to be something out of the ordinary coming out.

Components Samsung Galaxy A7
Design and Management
A unique feature of the housing A7 did not get – we are familiar with your smartphone on the rest of the Galaxy family of appearance . This proportion, however, destined to any successful product: it is enough to recall the range of premium German automakers, where cars of the brand, from the family to the premium remind platoon dolls.
With luxury cars and associated design smartphone – black body with playing in the sun faces “chrome” is impressive. Galaxy A7 looks stressed strongly, and after the departure of the dominance of plastic in favor of metal smartphone has changed as dramatically, like a real bouncer, who succeeded tracksuit on a tuxedo.
But in the first few minutes of studying the body Smartphone impression that metal something Koreans stingy! If the frame around the perimeter of the housing cools convincingly arm lifts and inspires suspicion, being very hard, the rough stuff on the back of the puzzles. Fears that Samsung smartphones secretly equips metal with a plastic lid, in fact groundless – back of the Galaxy A7 is really made of metal, it is covered with a thick layer of matte paint and therefore became much more like the plastic to use.
This compromise Samsung went from practical considerations, “pleasant coolness” of the metal in the winter is not so pleasant, and in the summer smartphone can warm up to indecent temperature, just lying on the table under the direct rays of the sun. Bury so attractive smartfrn in a case and make it even bigger wants not everyone. Therefore, the metal back cover has been used not for the image, and for good – it increases the strength of Galaxy A7, and rough surface helps him not slip in your hands and do not freeze to the palms, regardless of the temperature of the body.
Thanks to modest the thickness of the smartphone well in the hand, and the location of the volume keys and lock the display is optimal for such a big gadget. However, hardware Home key is necessary to make “descent” fingers on the sides and rear panel, if not “surrender” and use your smartphone with two hands. And when this level of comfort is not satisfied – rescue zoom mode display that allows to squeeze in every corner all the Android interface with the shell TouchWiz.
toughened glass Gorilla Glass to show their best side – this week Galaxy A7 operation without the cover on appears not a single scratch, and oleophobic coating retained display clean, preventing the appearance of fingerprints.
Four palely “notches” – two on the top and bottom faces – radioprovodyaschie area for Wi-Fi, GPS and 4G / 3G. With the habit they can be mistaken for oblezshy chrome metal frame, but the example of competitors should be noted that in this sacrifice A7 level of network reception looks not so intrusive.
«You sandwich without bread or without sausage?” – two trays on the right side of the smartphone offer equally absurd choice: two cards of the nano-SIM, or one card for calls + memory card micro SD. Amount of internal storage in the smartphone is modest by today’s standards 16 GB, of which the user is available only 11.5 GB. Those who prefer to combine the smartphone and personal work number will experience a shortage of memory for video recording or playing games, while the remaining buyers would catch myself thinking that the Galaxy A7 Duos in fact turns out to be “not quite Duos».

foothold on the back of the smartphone is always acting on the back of the camera body: Galaxy A7 thus “privstaёt on tiptoe”, so speakerphone never dulled. But the metal frame around the camera will lose presentable appearance very soon. Microphones located in the smartphone more successfully and have chosen the upper and lower bound.
She rear camera – forced and not the best entry point for smartphone
Among the present output connectors on the 3.5 mm headset jack and Micro USB with support OTG technology for connecting peripheral devices and drives. Popular nowadays standard MHL, allows you to display an image from your smartphone on the TV while simultaneously charging in Galaxy A7 missing. Turn your smartphone into “video recorder” buyers have wireless technology Miracast.

Screen
Samsung Galaxy A7 is equipped with a display diagonal of 5.5 inches on the basis of matrix of Super AMOLED. To fashion Phablet no impact on sales Note 4, the matrix resolution of 1920×1080 pixels limited. For the model 2015 issue – not a record, but the image density of 400 pixels per inch is unlikely to disappoint even owners with a very sharp vision. But in Galaxy A7 uses PenTile – figuratively speaking, “dilute” pixels slightly reduces the sharpness of the image AMOLED matrices. Will they annoy the owners of our smartphone?
In fact – no. Discover the naked eye the differences in definition between the image on the screen Galaxy A7 competitors based on IPS matrices is almost impossible. The visual difference will be reduced only to the traditionally higher saturation display Samsung and ideal representation of black (which is why, by the way, it is not possible to calculate the contrast of the display).

For those who irritate saturated hues, characteristic matrix Super AMOLED, the manufacturer has developed several preset color. Admirers pictures IPS- displays can safely choose mode “main” – the picture lost their aggressiveness and the colors come close to the reference to edit photos or videos. Modes “movie AMOLED» and «Photo AMOLED» has once again exploit the characteristic features of the matrix, with “film” has the most spectacular settings with little skewed in cool shades. “Adaptive Display” adjusts colors to the discretion of Samsung, however, only within the limits of standard applications.
The viewing angles are excellent – the usual loss of contrast in the display deviation is reduced here to a minimum, and no air gap between the cover glass and the matrix allows a better look at the information on your smartphone on a sunny day. Cherry on the cake stands display support 10 multi-touch – a question of prestige, moreover, on the 5,5-inch Phablet other indicators would look unseemly sparingly.

Sound
Samsung Galaxy A7 sounds mundane – single speaker on the rear metal panel produces high volume and struggling to not “misquote” the sound of music, regardless of style. Percussion instruments do not merge into a mess, and the details of the arrangements do not fall out of the picture. The bass is not at all, but not so much high as it could be – almost always smartphone plays music absolutely dispassionately
Entries live music or studio tracks from the many-voiced singing sound, however, “thermonuclear” – all voices merge into a “monster cry,” and howls smartphone, drowning all instrumental accompaniment. In general, overly passionate compositions ringtone in the Galaxy A7 will not work, but in other cases Phablet prove themselves worthy.
But Samsung A7 is able to emulate the “warm tube sound”! In fact, the function SoundAlive with FX tube amp has little effect on the sound, and instead packed into squares presets audiophiles immediately use manual adjustment equalizer.
Music mood – one flick of the wrist
Much more curious looks feature “Music Square” – it allows, they say, by his heart indicate their wishes to the music and the system on the basis of amplitude in the tracks will select the most suitable compositions. Pleased to note that the results of automation often coincide with the desired.
Hardware
«Heart» Samsung Galaxy A7 – Qualcomm Snapdragon processor 615, which was announced at the MWC in February 2014. The chip is a bit out of sorts Qualcomm, whose ideology “smaller nuclei – above efficiency per clock” at some point came to a standstill, after which the company produced 64-bit eight-chips that before so actively criticized.
In result, the light went out the answer to the famous Californian vosmiyaderniku MediaTek MT6592, however, has a more elegant platform. If MediaTek, without further ado, were founded upon the core archaic and not very productive architecture Cortex-A7, Qualcomm is already used more sophisticated core Cortex-A53. However, in the line of ARM, they are positioned as rather modest solution for middle-end devices. In the flagship Snapdragon 810, for example, four core Cortex-A53 are used as the unit for operation in moderate load. A truly high performance it falls on the remaining four core Cortex-A57, which in the premium segment Qualcomm replaced previously nurtured his own architecture core Krait.
As against this background that looks like Qualcomm Snapdragon 615? The usual configuration big.LITTLE originally implemented in it – instead of “mismatched” blocks of four cores using eight cores of the same type -Cortex-A53. The frequency of the first four cores at 1.7 GHz, and the second quad-core Cortex-A53 unit was already 1.7 GHz.
The advantages of the new platform in the following:
– The nuclei Cortex-A53 themselves on its own economical architecture Krait, but with the ability to separate off an eight-chip in most cases would be more economical than its predecessor.
– The once-flagship accelerator Adreno 320 is now redesigned to level up to middle-end and was named Adreno 405. Of the innovations – gaming technology support DirectX 11.2, and OpenGL ES 3.1 and hardware acceleration format H.265 (HEVC) until the resolution of 1920×1080 pixels at 60 f / s.
– Integrated modem now supports networks LTE cat. 4 and Dual SIM «out of the box».
As a result, in comparison with the same MT6592, which is equipped with the flagship brand of the second tier, economical Snapdragon has a powerful 20% in graphic disciplines, and 5% weaker processor performance. But next to the Snapdragon 805 installed in the Sony Xperia Z3, HTC One M8 and some versions of the Samsung Galaxy S5, hardware stuffing the hero of our test is almost a quarter less. As a result, the results of Snapdragon 615 okazalis closest to the masthead chip 2013 – Qualcomm Snapdragon 800.
In fact, the power level LG Nexus 5 or Samsung Galaxy Note 3 for Full HD display enough today, but to compete with the flagship 2015 performance on our smartphone is not able to.
In everyday use features Samsung Galaxy A7 chip is more than enough – all modern games start and run at a high level of detail, and two gigabytes of RAM today is enough for a comfortable switching between messenger, browser and video player, even with the “parasite” on top of the shell manufacturer.
By the way, the notorious TouchWiz in the current version does not lead to a breakthrough in the scroll or even prevent the rapid change of orientation of the display. Heat level smartphone remains in the normal range even after several hours of gaming – competent implementation metal housing, for example, allows you to not be afraid of that Galaxy A7 «boil” on the dashboard of a car in the summer and goes down.
Level reception of 3G and 4G is not satisfactory, as the sensitivity of Wi-Fi.
The speaker volume is average, but he has a nice voice and caller’s voice is not only a member of the high frequencies. Potential speakerphone also no surprise – a number of champions will be able to “shout” voice of the caller a little louder, on a busy street of the speaker will be desperately missed, and in all other cases, the performance will not be satisfactory.
