In 2015, Samsung did an experiment, he removed the option of memory card from the smartphone, as well as they release two same size smartphone one with the edge and another one without the edge.

In the start, big screen scared off users, but then we noticed that Edge phone make the significant increase in sale. People started liking Edge screen phone. first 3 months was very busy for the S6 edge. Even Samsung has to reproduce it for their customers. We must say that the fashion of edge smartphone is introduced by Samsung.

After the success of the first Edge phone. Samsung release Note 5 Edge and S6 Edge Plus. Initially, Note 5 / S6 EDGE Plus was released for Asia, south Korea, and united state but their popularity demands to release is for every other region.

Now in 2016, EDGE comes again in S7 but this time, the screen size is changed. Now the user has two choice either go for regular version or select big screen edge model. As for me, this approach seems more logical than the two equal-sized apparatus.

So now for the next 6 month, S7 / S7 EDGE will be the Flagship handset by Samsung. In which they did not do any compromises in development and features. Apparently, history repeats like S6 / S6 EDGE, but if you see the market response , it is awesome.
Pre-orders in Europe and Russia showed that the main demand is for S7 EDGE. so today we are going to review each and every part of Galaxy S7 Edge flagship handset

Design, body materials

As I discussed above the experiment of Samsung in 2015 is now paying them off because the redesign of the flagship handset is now becoming successful, and now they are all built on a metal frame, have the rear surface of Corning Gorilla Glass 4. they also added 2.5D back and front panel in Glass, now this design is followed by every other mobile phone manufactured.

As you can see that Samsung A-2016 series is quite similar to this flagship smartphone without edge only the colors are different. it is hard to distinguish between color and body of the smartphone. That is why people are looking for edge phone for a change. This year, the iPhone 7 will receive a different appearance, but the Galaxy S7 will resemble its predecessor.

if you see the colors of Galaxy S7 Edge Black Onyx looks interesting, golden color and a little tired in the previous model. And most of the people ordering the phone in black.

The bad point of Galaxy S7 edge is that you can not replace the battery of that phone. But it can be done in any service center. The second point is , it has protection from water. Just as in the Galaxy S5, Now Samsung follows IP68 protection standard. There impregnation of components on the board with a special solution, water repellent (like its use in Motorola phones), but also the design does not allow water to get inside, to the speaker and microphone specially.

And this is protected microUSB-socket to prevent water from getting inside, and if it does happen from the impact, then there is a special controller to prevent short-circuiting.

All metal surfaces subjected to additional rustproofing. In the picture, you can see the shaded part of that additional protection against water.

We conducted the test for compliance with IP68, the phone easily passed it. No problems with it there, Just want to point out that after water test its dynamics remain same it did not dull the is necessary that the unit has dried, it is simple logic that somehow individuals is unclear.

Note that what’s inside the tray for the SIM-card and memory card, it has a rubber insert, which is lower than the upper bound. As a result, here quickly stuffed dust from pockets, but it does not penetrate into the phone.

It affects the feature of his defense. Someone may not like it from an aesthetic point of view, but problems with that, as the dust inside the housing does not penetrate and can not get there.

The body of Galaxy S7 EDGE is big which means big battery inside. It is durable and its body is made of aluminum alloy 6013. Previous Galaxy user does not have any complaint regarding resistance to falls.


completely recalculated location of the components and parts of the phone to provide even greater survival and safety glasses that cover the screen and the back surface. Miracles do not happen, and you can break any device, but Galaxy / Note line users know that they have very reliable machines that are difficult to break.galaxy s7

Due to the fact that now and back cover of the phone has a bevel, keep S7 EDGE hands much better than its predecessor, no crashing parts, nothing even remotely disturbing. Excellent device for tactile sensations. The glass gets dirty, this should be accepted, another thing is that fingerprints are not so visible and easily erased.

I note the black version of the speaker grille, which is also painted black. The paint gets remove because of your denim pocket. The device did not warm inside created a special cooling system. Look at the description.

Memory and RAM

When the Samsung started out the production of its flagship memory cards, the company supposed that 32, 64 and 128 GB will be enough for their customers. Therefore, an experiment in Samsung considered unsuccessful

Then in 2015 they removed the memory card option from the phone, this was their biggest mistake. learning from their mistake now the memory card back into all flagships, you can use them almost any size. Map 200 GB is recognized and works. Later, support for memory cards is 2 TB may appear, this is no reason not to do not, no technical constraints. The basic model of Galaxy S7 has 32 GB and 64 GB internal memory.


Since the Samsung smartphones use faster memory standard UFS 2.0, the company had to abandon the original features Android 6 – unions memory cards and internal memory in a single array. It is necessary for those who are not going to use your card anywhere else but only in the same handset.

RAM of the type has not changed, it’s chips built on the first time we saw them a year ago, 20-nm technology. Peak data rate – 3.2 GB / c, which can be considered a top speed of mobile devices in the next year, or even a half. RAM up to 4 GB.IMG-20160407-WA0018

But because of the speed of the processor, while downloading applications from the cache was reduced at least twice, it seems that they hang in the memory. Visually, and feels it is a big increase in speed in this aspect.

Chipset and performance

In 2015, Samsung refused to use Qualcomm in its flagship processors because it get very hot and had a lot of flaws. This processor and Samsung waived brought down shares of Qualcomm and even caused a wave of layoffs and reorganization of the chipset manufacturer.

By 2015, the Exynos-options flagships noticeably worse than analogues at Qualcomm. Qualcomm is traditionally stronger than in their own solutions from Samsung.


The majority of countries will receive the flagship of Samsung Exynos version rather than Qualcomm 820. for the minuses I note Qualcomm version is less than about 10 percent of the time in different modes that looks like a huge difference for the same performance. It is also less integrated chipset from Qualcomm with the camera from Samsung can affect the speed of autofocus (but you do, most likely will not notice). Advantageously, the flagship version will be the one that uses the Exynos 8890 inside.


Depending on the operator and / or the chipset used will be different letter in the marking models, the standard name – SM-G935. Let’s dwell a little on this processor. So, it is powered by the technological process 14 nm FinFET, it has eight cores, as well as new graphics coprocessor MALI T880 MP12. In the graphics area alleged that the processor is 80 percent faster than MALI-T760, and energy efficiency above 40 percent at full load.


One of the interesting features of the chipset note support LTE cat.12 / 13, which provides data download speeds of up to 600 Mbit / c (film size of 1 GB can be downloaded in one minute, if your operator supports these categories). See infographic devoted to this processor.

In synthetic benchmarks with the Exynos version shows better performance.

In tests it wins S7 EDGE, the fastest machine at the moment (my phone on Exynos). Look at test results.

I want to underline that the new processor is very fast. In every way it is one of the best processors on the market, and while it has good energy efficiency, reduced energy consumption, which, combined with other technical solutions make these models very interesting.


The handset also has an additional processor Exynos M1, it is responsible for shortchanging movements. Allocation for this separate, dedicated processor justified. At this point in the S Health is the wrong place counts steps when traveling in the car, shaking is perceived as walking. In the coming months this will be rectified.
