Since mid-March 2016 is Samsung Galaxy S7 Samsung Galaxy S7 as Duos variant for 2 SIM cards available. The range comes with either a flat5.1 inch Quad HD display, or, as S7 edge duo , with a double-curved 5.5-inch screen. Both models are mutually otherwise largely identical and also correspond to almost 1: 1 to the respective variants with a single SIM slot. How good is the Galaxy S7 in test as dual SIM phone ? We have the most important data for the various devices in the comparison .

First Conclusion of copious Test : The successor to the Galaxy S6 (test) continues the previous design, but improves various performance levels to new highs. Below we respond to the information about features, properties and first reviews. Before you find here but first of all at a glance the different S7 versions which there are: With flat and curved screen and with one or two SIM places. Incidentally, all the other properties not or so minimal that they made our test vision differ between Duos- and single variants no difference make.
Galaxy S7 + edge + Duos comparison: differences and similarities
Display: 5.1 inches with 2560 × 1440 pixels
Basically there are no changes compared to its predecessor. Also the Galaxy S7 display has again ultra keen on, with the same amount of pixels and screen size. The combination of 5.1 inch, 2560 x 1440 pixels and 557 ppi pixel density had convinced us in the test tremendously. Add to this the excellent luminous color reproduction and the very good brightness of the Super AMOLED screen.
Unlike predicted or maintained by many, the touchscreen still works capacitively, but does not react to different pressure strength. Prior to the presentation, there were many rumors about such a potential Force touch display, as previously isolated from other manufacturers (Apple, Huawei) is offered. As usual in the top area, and the new flagship of Samsung can display 16.7 million colors.
Samsung Galaxy S7 edge Duos: 5.5 inches and displays page
The new generation has another choice in whose display are rounded at sides of the screen over the entire panel surface to the rear. What is new is the size in relation to the flat version: The “edge” is available for sale starting exclusively with 5.5-inch diagonal and thus significantly more viewing area.
Thus, the original form of the S6 edge has been deleted, and only the edge + obtain a direct successor. Whether it still is a smaller version later, is not yet known. The image resolution is the same: The 2560 x 1440 pixels on the screen WQHD have impressed us enormously already in the last test, and definitely no need for improvement.
- The concept of the operation, however, is basically the same as its predecessor. You can select one of the two side screens and drop as information services and app icons there respectively. So you have a quick access to frequently used messages inputs or his favorite applications. By wiping the inside of the screens you can then start the closeup.
- A useful additional feature on calls: You can define multiple contacts as VIP and assign a specific color. Gets one of these VIPs, the display lights in the corresponding color. If the S7 edge while on the screen can be seen from the lateral illumination of the incoming call. To make calls you pull again the icon centered pull into the display.
Virtual Realtity: Gear VR goggles and Samsung Galaxy S7
When about a year ago, the previous flagship smartphone has come on the market, the ultra high resolution Quad HD was relatively useless. With an emphasis on relatively. Because the image reproduction total had outstanding brilliant to the test they gefielt us as good as any other mobile phone. But with the Samsung Galaxy S7 receive the 557 ppi on a new meaning. The manufacturer presents the Phone in the teaser spot as the perfect complement to its virtual reality glasses Samsung Gear VR. What has this to do with each other?
At normal viewing screen starting at 300 ppi with the naked eye no single pixel is more recognizable. But by putting a superphone like the Galaxy S7 in a VR housing as the Gear, to change. First, the viewing distance decreases to the panel within a few centimeters. Secondly, and especially provide special lenses that one has the impression of being completely surrounded by the screen. Here, the more refined image resolution therefore is clearly noticeable and is really useful.
Buy Galaxy S7 Duos without contract
After unboxing on February 21, it was only a matter of time until the Samsung mobile division also the Galaxy S7 duo presented. Who the Galaxy S7 Duos buy want, so can now access. Thus only a few weeks have passed between the unboxing and the launch ( “release date”). Thus, the pace has over its predecessors as the S6 already mentioned and the Galaxy S5 Duos (test) again increased. Because the two precursor came respectively on 11/04/2014 and 04/10/2015 on to the market. The sequel is so far off about a month earlier.
Galaxy S7 in Test: Unboxing and performance
Even if it’s just a matter of time for many, until they can order their next Samsung flagship model: still is for most fans, a Samsung Galaxy S7 test very important in deciding whether to buy the S6 successor or not. Therefore you will find here soon in addition to our own impressions and the first short test reports for classic flagship with only one SIM slot.
How well the S7 duo is compared?
As before, the “six” is considered one of the best smartphones ever. The S7 must therefore measure iPhone 6s with both the flagships of direct competitors such as Apple. Regarding the dual-SIM variant, however, the flagship devices like LG G4 and Duos Sony Xperia Z5 are the competition.
But not only the high-end models of other brands are the S7 duo comparison in focus, but also devices from their own ranks. Because the quality of past Super Phones sets the bar.And within about a year, the technology is evolving rapidly. This also means: If the S7 should only cut off a bit better in the test than its predecessor, which was a little disappointing.
In fact, there are significant improvements of the already familiar characteristics. And. In almost all areas, but especially in the speed Yet another point is important when deciding: Who wants to buy a new S7, has to decide yes between the classical and the laterally curved display. Which has since ahead?
Availability in Germany
The exact characteristics of surfing we could not view or test.Because the Galaxy S7 duo will most likely surpass the achievements of his predecessor, whose properties are in our view, the minimum standard for the S7. This includes not only LTE to 300 Mbit / s, but also the possibility of the couple the Download via mobile Internet via Wi-Fi, so you can especially great apps, files or stream movies even faster.
Meanwhile, for some time now circulating on the following numbers:600 Mbit / s should be the maximum downlink speed when the phone on LTE Cat.9 or Cat.12 may have recourse. In Germany but is currently unserers knowledge no such high data throughput in mobile available.
Important when buying, especially in rural areas: to support 4G frequencies eighth. For some LTE dual SIM phones , which came in the last few months on the market, lacking the 800 MHz band. But this is particularly common in sparsely populated areas.
For cities and metropolitan areas, it does not so decisive role, there are mainly two other bands (1800 and 2600 MHz) verbreitet.Diese be generally supported. However you should make the agreement on who is the provider: The 1800s-frequency is eg supported by Telekom and the former E-Plus LTE network.
With Android 6.0 , the new top smartphone of Koreans has expected to released the latest version of the Google operating system and at the S7 used.
In addition, the cell phone providers reinstalled as with virtually all other devices including the new superphone its own TouchWiz interface.This is for a class, because the user interface provides some very handy extras. On the other hand, there are Android fans, where the pure OS would prefer. We currently any case assume that TouchWiz is preinstalled.
Appearance and color
The previous S flagship was over its predecessor a huge leap in terms of material selection and processing. From plastic and metal optics towards glass and genuine metal . The new generation will change it – nothing. The overall impression of the enstpricht the precursor. Of course, there are some modifications. But you have to say in fairness: The base of the S6 was so high, that can increase an S7 design and quality barely.
The situation is different in function. The housing is both dustproof and waterproof in accordance with IP 68 class certification. So that makes it a huge advantage betting, the hitherto specifically the Sony Xperia Z5 Dual in the test provides. In order for the IP class is even better than the once mentioned as IP67 Leakd beforehand. Important thing is that you still can not do everything possible to organize the S7. The IP Zertifitizierung not apply eg for Coke or saltwater. In particular, the second digit is interesting: The “8” indicates namely: “Protected against water penetration when dipping with no time limit.”
Of course, the Galaxy S7 in various’s colors available. This leads, at least so far, to no surprises. The manufacturer calls black, white and gold.The latter will be to purchase at a later time. A bold color such as Rosé takes Samsung therefore not in the assortment on.
The camera is at least for those who like to take pictures, probably the highlight of the S7. And although the resolution back in megapixels. For instead, the manufacturer uses a significantly improved aperture and an optimized sensor. In detail, this means among other things:
- Main camera with 12 megapixels (instead of the previous 16 megapixels) and UHD (4K) video recording
- Front camera with 5 megapixels unchanged
- Aperture f / 1.7 – this is the brightest aperture so far in our test. By comparison, the S7 would S6 (f / 1.9) exceed by 0.2 points, a huge difference in difficult lighting conditions.
- Dual Pixel AF function, as it has been used in digital SLR Canon
- Single 1/2 inch image sensor
Especially when shooting in twilight means a lower aperture value distinct advantages : Because the optics can be more residual light on the sensor. So you can get clear photos even in fairly dark places, instead of recording only pixel noise.
A very different point that has nothing to do with the image quality: the previously protruding optics disappears with the new generation again more aligned to the rear housing. Although it did not bother us in the test, which is definitely more comfortable in your hand or in your pocket.
In Duos variant of the Samsung flagship provide two nano-SIM cards for cellular network coverage. However, there is still only one SIM slot at the top edge of the case. Excluding the SIM carriage come forth as usual with a thin pen, the difference between the duo and single version is only seen at second glance: In addition to the already existing SIM place is microSD slot provided with an additional recess.This can be there instead of the memory card optionally also now (second) nano-SIM use. Inside the housing is located at the corresponding point a second SIM contact point.
The advantage: You do not need extra slot in the housing, all dimensions are the mono-SIM S7. The downside: You have to decide whether you want to use a second phone number or additional memory in phone. If one of two SIM cards one, you can use any microSD . This is important, as the S7 in all variants (at least so far) is equipped only with 32GB of internal memory.
Who 32GB of photos, songs and games are not enough, in the dual-SIM version therefore can not easily upgrade additional storage via microSD. However, files can become very good by Cloud outsource, save locally or specifically retrieve songs and videos via streaming. The costs, however mobile data volume . Us it is not disturbed in the Galaxy S7 test, optimally this hybrid solution is not sure.
Parallel to the many rumors circulating around the Galaxy S7 also some news in terms of ” eSIM “. It is a new technology, to which, among other things Samsung and Apple have partnered. The data of a SIM card is no longer stored on removable media, but directly deposited on a chip in the phone. eSIM means “embedded SIM”, eg “integrated SIM”.
The first eSIM smartphones to 2016 come on the market. The Galaxy S7 is not yet equipped – thus the issues are not acute, whether it is more of the consumer at the eSIM to progress or whether there is in practice more disadvantages. Presumably it will be shown at the Apple iPhone 7 in autumn 2016. The flagship of the Koreans has however continued the classic tray insert to both cards.
When S6 especially having quick charge can score. This function has Samsung also packed the new model and possibly even improved – that needs to be tested after the presentation. Last was rumored that the time for wireless charging 120 minutes in the classic version and 2.2 hours should be at the edge variation.
Important it was for the provider, however, the capacity of the S7 Duos battery boost. It is precisely when one uses the many ways that the battery backup power for the high resolution and very high computing power are dwindling.
With 2550 mAh, the earlier generation as significantly less power than others, some much cheaper phones. 3000 mAh are therefore a welcome improvement. Again more, namely 3600 mAh , provides the battery in the 5.5-inch S7 edge Duos variant. The consumed with its 0.4 inches wider screen also correspondingly more power.
High-end smartphone to-date, and the 2 SIM card slots: The Galaxy S7 Duos offers currently in our view best overall all Dual.SIM Endgeröte.However, an even more hefty price. Who currently uses a much weaker smartphone, can also take the S7 predecessor or find in a dual SIM superphone competitors very good and fast phones. Anyone can grab a little deeper into the pocket, replaced with the new Galaxy but peak performance in almost every respect.
- Very powerful
- Very good material quality
- All German LTE frequencies
- High price
What should I do if I want to buy a Galaxy S7 Duos?
Since the devices are available as an import, you have to pay particular attention to the mobile radio frequencies. Samsung manufactures the duo versions of its smartphone not for Germany but for other markets. Therefore, the frequencies (or “bands” referred to) may not completely congruent with those that provide local mobile provider.
With 2G (GSM, GPRS) and 3G (UMTS, HSPA +), the frequencies are actually getting geeigent also for Germany. Deviations were at the best models in the test last only for LTE. The 4G module in S7 duo has 800 support in 1800 and 2600 MHz. In particular, the band 20 (800 MHz) is sometimes missing. So it was in the predecessor Galaxy S6: after a few weeks there was a facelift, which also this band has been covered.Especially in rural areas many radio cells on this low bandwidth.
There are also various processor variants, the respective output is very similar. This is also true for the S7 cellphones with a single SIM slot.Because this will get different chipsets according to the regions. This should in principle probably play no role in the use. If you place value on a duo model to buy the same chips as the officially available in Germany Version: In the Galaxy S7 compared the top of this page you will find the relevant details given.
Since when I can buy the Galaxy S7?
The presentation took place on the Galaxy Unpacked event held before the MWC 2016 launch of the single-SIM version was the 03/11/2016. The variants of S7 and edge with 2 SIM slots are since 16:03. commercially – but especially abroad. The first vendor we could find, is a mobile phone shop in China, who sent his goods from the UK.
Already knew? Samsung tried to release date apparently with all the power to help the S7 to success. Why has mobile provider started a free action. Who edge the S7 or S7 ordered before the launch (directly from Samsung or a partner who takes part in the action), according to the official website received a virtual-reality goggles Gear VR to. This was the extent, however, we know only for the single-SIM version. For the Galaxy S7 duo there was this extra not appear.
