The Samsung Galaxy S Duos S7562 is another device in the mid-size segment with normal hardware. “Dual Sim” is the keyword for the outstanding feature of the Samsung Galaxy S Duos.
Does this sound familiar? – One traveling abroad, but would not give up its accessibility with their own mobile phone, at the same time, however, do not fall victim to the high cost of roaming. For such problems, a dual SIM smartphone has an elegant solution: The device is able to accommodate two SIM cards at the same time and this dial into the respective networks. In areas where, for example, the employer gets a cell phone contract provided, but also wants to use the private contractors, such dual SIM devices are often used.
Reasons mentioned above, currently pushing more and more smartphones with dual SIM technology to market. However, when viewed from directly hitting the tender: The available devices are not all high-end devices such as the Samsung Galaxy S3.
Samsung Galaxy S Duos S7562 Housing
Samsung remains true with this device and its line uses no metal on the outside of the housing. The display frame and the entire body are made of plastic, which obviously has an impact on the weight. The result is that the complete unit with battery weighs only 4.2 ounces. The battery cover is matte white, a feature which pleased us greatly. As usual in this device segment a glossy display is installed. The plastic frame is silver colored and strongly reminiscent of the surface texture of brushed aluminum. Since Samsung is a master in the use of polycarbonates, we found in this Samsung Galaxy device no deficiencies in terms of rigidity and processing. All gaps are uniform and the Samsung Galaxy S Duos S7562 smartphone is processed completely clean. The pressure point of the volume rocker and the power button is used well, the pressure point of the “home button” is haptically even better. Because of the design and layout of the buttons is very similar to the Galaxy S3. For the dimensions we see marked differences. The Galaxy S DUOS is not as thin (10.5 mm) as the Galaxy S2 (8.5 mm) or S3 (8.6 mm), but it also is not as wide (63 mm) and high (122 mm). By the smaller dimensions of width and height, it is very good in the hand and can be easily operated with one hand. Currently, the smartphone is only available in “pure white” and “black”.
The Equipment of Samsung Galaxy S Duos GT-S7562
As already described, the Galaxy S3 and Galaxy S DUOS are visually similar, except for the dimensions. This is also evident in the built-in buttons. At the right edge of the case the power button is attached. On the opposite side, we find the volume rocker, positioned in the upper third of the edge. Left and right of the physical “home button” there is ever a touch button to navigate to other menus or the system can open.
For charging and for connecting the smartphone to a PC to the micro-USB 2.0 port is on the bottom side. The recognition as a mass storage worked right away. On top of the 3.5-mm stereo phone jack is installed. The Micro-SD card slot can handle memory cards up to 32 GB and is not installed in this model under the battery cover, but on the right side of body. A small cap protects the port from dirt. From the factory to the unit’s internal memory are a mere 1.78 GB available, so no external memory card is almost inevitable. Unfortunately, Samsung has no model of the Samsung Galaxy S Duos S7562 with larger storage devices in the portfolio.
Software, Communications & GPS
Samsung delivers its Dual SIM Smartphone with Android 4.0.4 (Ice Cream Sandwich, ICS) and its own Touchwiz 4.0. As usual with Samsung smartphones we also find a range of preinstalled software like Messenger ChatON, Game Hub and Samsung Apps.
The communication modules must not hide Samsung Galaxy S Duos S7562 from its bigger brothers, and certainly not in front of his dual direct competitors like the Sony Xperia Tipo. The integrated wireless module transmits with the 802.11 b / g / n. Even with such a smartphone may not be missing a fast mobile internet connection. The HSDPA unit receives data at a maximum throughput of 7.2 megabits per second. A special feature of the test device, the two radio modules, which each represent a quad band + W-CDMA (1900/1800/900/850 MHz) are available. This allows the dual SIM phones, but more on this in the “dual SIM function.”
Other features include Bluetooth 3.0 and A-GPS (Assisted-GPS). The GPS receiver, the signal is immediately, even in confined spaces in the vicinity of a window.
The special highlight of this device is undoubtedly the ability to operate two SIM cards simultaneously. So you can take advantage of the benefits of different contracts or prepaid cards to take advantage. For example, a contract is particularly favorable order abroad to use mobile data services, so you can continue to use its standard tariff for making calls abroad coupled with cost online. The various possibilities are very diverse and can be customized without having to constantly change the SIM card and without having more than one device with you.
At least as interesting as the function itself and its implementation, ie how the feature is implemented in the software. When entering the PIN you have already noticed that this is not a normal mobile phone. Direct succession to the PINs of the two SIM cards to be entered – and then falls to the next feature: The status bar shows two reception indicators, which means that both SIM cards are simultaneously connected with the respective network. Therefore it is possible to access both numbers. The dual SIM feature works very well in everyday life and brings many benefits. Why there are currently few devices with this feature on the market and why you have to search in vain for complete high-end smartphones, we can not explain.
For casual snapshots and video calls Samsung integrates two camera modules in the device. The main camera shoots at 5 megapixels on (2592 x 1944 pixels), and the software provides you with 4X digital zoom. The front camera has significantly worse and provides a resolution of 640 x 480 pixels, thus has 0.3 megapixels. For applications such as Skype is enough. Unfortunately, videos can be recorded by two cameras with a maximum resolution of 640 x 480 pixels.
In practical tests in indoor the images are too pale and not as rich in color as that of the Samsung Galaxy S3. When shooting outdoors, the blueness not so much weight, but it also notes the lack of clear color intensity.
Samsung Galaxy S Duos S7562 used in a capacitive touchscreen, as we know from all current smartphones. The display responds more precisely and accurately to inputs. Multi-touch gestures such as pinch-to-zoom and tap-to-zoom will work as expected accurately and quickly. The preinstalled Touch keyboard can of course be changed at will. Here in the example left the default keyboard from Samsung can be seen on the right and installed a keyboard app from the Google Play Store (SwiftKey 3). Additional software usually has the advantage of being considerably more settings can be set and look and feel can be customized entirely to your needs.
Samsung’s top sellers like the Galaxy S2 and the Galaxy S3 feature Super AMOLED + panel with the very rich color representation. Samsung Galaxy S Duos S7562 however is unfortunately not equipped with this technology. Instead, under the touch screen works a 4-inch TFT display. This corresponds to a screen size of 10.16 cm. The Galaxy S2 features a 4.3-inch display and the Galaxy S3 even about 4.8 inches. The display resolution of 480 x 800 pixels results in the present display a pixel density of 233 ppi. The Galaxy S2 even has a lower pixel density of 217 ppi. One missing feature is the automatic brightness control. In many current smartphones brightness sensors on top of the touchscreen are installed, which reduces control depending on the light screen brightness. To the lack of function a little justice, Samsung has in the vertical slider menu programmed the ability to change the currently required brightness quickly. This saves the path in the settings.
The measurement of display brightness with the Gossen Mavo monitor provides information about the actual brightness and black level. In the middle of the display, we measure the maximum brightness of 342 cd / m². In the peripheral regions, this value falls from up to 315 cd / m². As a whole, results in an average brightness of 326.7 cd / m². Thus, the display is about 30 cd / m lighter than the HTC One S. The coverage reached 92% of a very acceptable value for the TFT display. Because of the technology, the black level is not the exceptional values of a Super AMOLED + – build or IPS displays. We measure here 0.66 cd / m², the resulting contrast is 518:1.
The Samsung Galaxy S Duos GT-S7562 is a Qualcomm MSM7227A with a Snapdragon ARM Cortex-A7-single-core processor, which operates at a clock frequency of 1 GHz. Other features include a 512-MB of memory and a 1.78 GB of internal memory. For graphics applications the PowerVR SGX 540 GPU is responsible. This GPU also came in the second edition of the Samsung Galaxy S2 (I9100G).
The test results reflect the performance of the installed hardware again. The Samsung Galaxy S Duos S7562 is clearly inferior to the quality competitors. Even 17 months old Samsung Google Nexus S, which has the same GPU has the same processor speed and also has 512 MB RAM, cuts better in almost all benchmarks. In synthetic benchmarks, such as the Base Mark ES 2.0 is the performance difference between the Galaxy S3 and Samsung Galaxy S Duos S7562 whopping 704%. With browser-based benchmarks, the difference is not quite as extreme, but still very evident. The consideration of the write speed in AndroBench accuses clear also that this is at best is a mid-range model.
Recent games such as all versions of “Angry Birds” run smoothly on the Samsung Galaxy S Duos S7562. The integrated SoC is also powerful enough to “GTA III”, a well-known 3D game to play fluently in less detail can.
Full HD movies however, can not be played on the Galaxy S Duos.
Call quality is consistently good, but we is at various telephone calls noticed that the neighbor’s voice has a slightly muffled. The built-in speaker, both in the “free mode” and in “normal mode” has a sufficient high level, but slightly distorted and tinny from 80 percent of the maximum volume. The correspondent can be well understood in stronger noise. From the opposite side, there were in our tests no complaints about the sound quality.
Since the hardware is not working with extremely high clock rates, the individual components are not overly hot. Under load, the area heated by the charging cable to up to 43.8 degrees Celsius. We suspect that there is also the SoC. All other areas have temperatures (on front and back) from 33.1 to 36.6 degrees Celsius. In idle mode, the temperatures for each segment 2 to 4 degrees Celsius lower to the charging port and even a whopping 12.6 degrees.
Samsung equipped the Samsung Galaxy S Duos S7562 a speaker directly to the left of the main camera. The maximum volume is sufficient in every case, but from about 75% of the maximum volume of the speaker sounds tinny and simultaneously began to distort slightly. Of a bass-driven rendition of course is not a trace. Despite the decent performance, we recommend to connect to external speakers via the 3.5-mm audio jack on the top side.
In our test the battery life, four scenarios were examined. Under full load, the battery is completely discharged within 4 hours and 51 minutes. This test was performed with the app “Stability Test” performed in order to simulate maximum processor utilization. A full battery charge then took 3 hours and 1 minute after charging through the socket. If the device is connected for charging into a USB port of a notebook, it is possible that the charging process takes longer to complete. At a brightness of about 150 cd / m and the wireless module is activated and with the aid of a script are easy surfing events simulated. In this case, the charged battery is about 9 hours and 25 minutes.
Conclusion on Samsung Galaxy S Duos GT-S7562 Review
The Samsung Galaxy S Duos S7562 is a very solid, cleanly designed smartphone with an interesting dual SIM feature. When we look for other smartphones with dual SIM technology, we notice first that the market is not very large, and the other one looks in vain performing alternatives.
The Samsung Galaxy S Duos S7562 with its built in hardware even a leader in the segment of the dual SIM smartphone The basic approach of the manufacturer thus goes in the right direction, but a significant increase in performance would have improved the overall rating strong. As memory and SoC are not able to play HD movies, and the built-in cameras are located around lengths short of the Samsung Galaxy S3.
With a current retail price of $350, the hardware used can not of course be at the highest level. The Samsung Galaxy S Duos S7562 is designed for persons who are on daily life need more than one SIM card.
