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

Buy Galaxy S7 Duos without contract

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
How well the S7 duo is compared?

Will also exciting: How would the S7-internal comparison of the two new models with a smooth 5.1-inch and 5.5-inch double curved edge phone from ?


Availability in Germany
If the model policy of Samsung you look at over the past few years, the mobile phone provider has less and less of its dual SIM models marketed in Germany. Especially the top devices of the S series, but also the popular A-series in this country is only available with a single SIM slot
. So it is no surprise that the manufacturer from Korea this marketing continue to maintain.

Abroad - mainly in Southeast Asia, Arab countries, Russia and South America - are the dual SIM variants of the Galaxy S7 hand back to the standard range. There were officially previously diverse models of all series for sale
with 2 SIM slots. So one has to free Importers recourse, or on online stores that accept the import from abroad.

Mobile Internet
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.

operating system
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.camera
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.
SIM slots

In Galaxy Duos S7 test can also be used for a second SIM in the nanoscale form of microSD place. The additional recess is missing the "normal" S7. Compared to other mobile phones, the name of the assignment (SIM1, SIM2) is legible.



battery pack
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.Conclusion
High-end smartphone to-date, and the 2 SIM card slots

- Very powerful
- Very good material quality

disadvantages
- 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
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
