Samsung Galaxy S Duos Review

You are currently viewing Samsung Galaxy S Duos Review

Given the now maximum commercialization and great accessibility of mobile phones, today many mobile phone users have the need to use 2 SIM cards and two numbers at the same time. Whether it is a private + business number or some other “combination”, the use of 2 numbers is not a fashion trend but an increasingly common need.

South Korean Samsung has always offered several dual SIM models, but the Samsung Galaxy S Duos has made a big leap over the infamous phones with the simplest possible functions whose only advantage was the dual SIM function. We see this progress in the Android operating system, a solid power processor, likable design touches. The former ugly duckling has grown into something quite beautiful, and whether this model is really as good as it seems to be, we will try to find out in the review of the Samsung Galaxy S Duos model that follows…


Samsung’s design team did not think much when it comes to the design of the Galaxy S Duos but used an already tried and successful recipe, a design that irresistibly resembles the Samsung Galaxy S3 model of high class but also the top design. We don’t blame Samsung for this move, because it breathed the look and style of a top-class into a lower-class phone.

This model measures 121.5 x 63.1 x 10.5 mm and is an extremely comfortable phone to hold and fits nicely in your hand. In terms of dimensions, this model is slightly larger than the Samsung Galaxy Ace model, but with its design skills and advances in technology, this model has a much larger display, which is commendable. This model is made of plastic, but thanks to its dimensions, it is a very compact and sturdy phone with an acceptable weight of 120 grams.

Above the display is a secondary VGA camera and proximity sensor, below the display is a hardware button for home and two capacitive buttons for Menu and Back. On the right side of the phone are the on-off button and the Micro SD card slot. A volume control button is located on the left side. There is a 3.5mm jack on the top of the phone, and a Micro USB port and microphone on the bottom of the device.


The Samsung Galaxy S duos is equipped with a 4-inch TFT display with a resolution of 480 x 800 pixels with a density of 223 pixels per inch. These are more than decent “figures” for a device of this class. The colors and contrast on this model are great, with the objection to reviewing the contents in stronger sunlight. Namely, this model does not have an ambient light sensor that controls the automatic adjustment of the brightness of the display, and when using this model in enhanced sunlight, the reflection is enhanced, but we would not be honest if we said that the display is unusable.


The first and basic feature of this phone is its Dual SIM (Dual stand by) function. What was proven by tests was confirmed by the first users of this model, and that is the fact that this model has an excellent signal even in areas where the network coverage is lower. What people would say is a good signal. Both cards have both 2G and 3G support, which is very positive, because you don’t need to think about which slot to put the card from which you plan to access 3G internet, for example.

The engine of the Samsung Galaxy S Duos is a Qualcomm S1 Cortex-A5 processor, 1 GHz. The Adreno 200 GPU chip is in charge of graphics, and this model also boasts 768 MB of RAM. This set is valid for the “classic setting” of mid-range devices that provide solid performance. According to testing, web browsing, playing sun games at a solid level. The Samsung Galaxy S Duos is designed to be an energy-efficient phone, and it’s not a “racing machine”, if you’re a more demanding user and expect extra high performance from your phone, this is not the device for you. We think that a different CPU (maybe NovaThor) with this model would give much better results without pushing the price of this model too much.


From a software point of view, this phone is at the top of current software “trends” in terms of the operating system. The Samsung Galaxy S duos work with the Android 4.0.4 Ice Cream Sandwich operating system and the latest TouchWiz user interface. Only the functioning of the phone is fluid, applications run without braking and the phone menu itself is quite a user friendly (easy to operate),


The Samsung Galaxy S Duos is equipped with a 5 MP camera that captures photos with a maximum resolution of 2560 x 1920 pixels. The camera interface is practically the same as with the Galaxy S3. What is positive about this interface is that during a shooting on the left side, you are offered shooting mode options that can be edited as desired. This way, your favorite or most commonly used mode is always

“At hand.” Geotagging, smile detection, and panorama mode are available to Samsung Galaxy S Duos users. The images made with this model are of high quality with vivid colors, with minimal levels of “external noise”, and rich image details. All in all, in this price range we are more than satisfied with this camera.

Battery and memory

This model is equipped with a 1500mAh Li-Ion battery and according to Samsung lasts almost 8:30 hours of talk time or 330 hours in standby mode on the 3G network. Switch to 2G, and the battery performance improves to 13 hours of talk time and 450 hours of standby mode. The battery of this model also provides 5:30 h of web surfing via Wi-Fi connection, 4:30 h of video views


The Samsung Galaxy S Duos is ranked as one of the most complete and best Dual SIM models available on the commercial market today. He met our expectations, and it turned out that in the box you will “find exactly what is written on the box.” The Samsung Galaxy S Duos justifies the efforts of its creators, and as far as consumer benefits are concerned, we are extremely glad that once only practical Dual SIM phones started to get a quality look and performance that exceeds the mere use of 2 numbers in one phone. is an affiliate.
