Exact copy of the flagship smartphone of 2012 from"Samsung" with improved specifications and support for two SIM cards - this is the Galaxy S3 Duos. Despite the fact that a lot of time has passed since the start of sales of this device, its characteristics still continue to be relevant. They, and also responses about this gadget will be in details considered in this article.
Niche smartphone
From the standpoint of the performance of the Galaxy S3 Duosfeel free to refer to entry-level solutions. But at the same time he has a slightly overpriced price. But this significant disadvantage is easily compensated by a number of characteristics (for example, the increased size of the diagonal of the touch display, the impressive capacity of the integrated drive, the improved parameters of the main camera). Therefore, this model of the smartphone is of the greatest interest for those who want an entry-level device, but with slightly improved parameters compared to competitors. Well, for these improved parameters will have to overpay. But, on the other hand, this is fully justified, because you get a device that is much easier and more convenient to work on.
Equipment
Phone Samsung Galaxy S3 Duos boasts standard equipment. It includes such components and, of course, accessories:
- Smartphone.
- The battery is 2100 mAh (it is inside the gadget and is removable).
- Advanced stereo headset with a set of nozzles.
- Charger.
- Interface cord.
- The quick start guide and warranty card are combined in one little book.
The body of the apparatus is mostly made ofplastic. To avoid possible damage during operation, you will have to immediately buy a case. Moreover, this device is almost an exact copy of the original flagship S3, and covers from the latter are ideal for S3 Duos. For the same reason, it is recommended to strongly purchase and stick a protective film for the touch screen. This will also allow to avoid possible damage in the process of work. Another important accessory is a memory card. It is also not in the delivery list, and therefore will have to buy separately. Although, in principle, the owner of this device can do without it. The capacity of the integrated drive allows it.
Design
In terms of design, the gadget is completely identical to itspredecessor of the Galaxy S3 Duos. A review of the appearance of these devices even allows you to distinguish between them. The only difference is in the inscription on the front panel, at the end of which the word Duos was added. On the front panel of the gadget, as expected, displayed a display with a diagonal of 4.8 inches. Below it there is a familiar control panel, which consists of a central mechanical button and two extreme touch buttons. Unlike most similar devices, in this case, the buttons have a backlight, which greatly simplifies the work on the smartphone with insufficient light levels. Above the screen there is a speaker, the "peephole" of the front camera and light and distance sensors. On the top edge of the smartphone is located only a wired audio jack of 3.5 mm. On the left side of the device, there are buttons for volume control, and on the right, locking buttons. At the bottom there is a micro USB connector and a microphone hole. On the back cover, in addition to the logo of the manufacturer and the inscription DUOS, there is also a hole in the main camera and LED backlight. Here is the main speaker, which is hidden behind a metal mesh.
CPU
Galaxy S3 Duos as ComputingThe platform uses a time-tested and very reliable chip - this is Snapdragon 400, developed by Qualkom. It consists of 4 computational models of the Cortex A7 architecture. Each of them can accelerate to 1.4 GHz at maximum load. It is also made on 28-nm process technology. All this allows him to combine an acceptable level of computing performance and high energy efficiency. To solve most of the everyday tasks of this semiconductor crystal is more than enough. This list includes video playback, listening to music and radio, reading books, browsing the Internet. But the most demanding games of the last generation certainly will not run on this device. Most of them are optimized for 64-bit computing, and this chip can process only 32 bits in one clock cycle. Hence the problems with their launch.
Display device and graphics
Very high quality display in the Galaxy S3 Duos. His characteristics are as follows:
- Manufacturing technology of the matrix - "SuperAMOLED".
- Resolution - 1280x720.
- The diagonal of the display is 4.8 inches.
Such technical specifications requiregood graphics accelerator. In this case, the “Adreno 305” is used. Of course, he certainly can’t boast a transcendental level of performance, but it’s certainly not necessary to expect this from an entry-level device. However, for most everyday tasks, its presence is quite enough.
Cameras
Just a great main camera in Samsung GalaxyS3 Duos. She has a sensitive element of 8 Mp. Also implemented autofocus technology, there is a digital zoom. Well, in the dark a high-quality snapshot will allow you to get, even single, LED backlight. As a result, the quality of the photo is very good quality. With video recording, everything is fine too. The resolution of the rollers can reach 1920x1080. In this case, the image will be updated 30 times per second. More modest options for the front camera. She has a 1.9 megapixel sensor. Therefore, a quality "selfie" in this case is out of the question. But for video communication this is more than enough.
Memory
1.5 GB is the amount of RAM in the Galaxy S3 Duos.16 GB is the capacity of the integrated drive. This will be enough for the average user to work and rest. If for some reason you need to increase the amount of memory in the device, then you can install an external flash drive. Moreover, its maximum volume can be equal to 64 GB. For greater reliability, the most valuable information is recommended to store on cloud services. This will prevent its loss in case of theft or breakdown of the “smart” phone.
Device autonomy
High autonomy can not boastSamsung Galaxy S3 Duos. The main reason here is the battery capacity of 2100 mAh. In a case with a thickness of 8.6 mm, a larger battery is difficult to put. Add to this the presence of two SIM cards and a display diagonal of 4.8 inches. To a certain extent, the problem is solved by an energy-efficient processor, but this is not enough to fully address this issue. As a result, all the previously mentioned factors lead to the fact that at maximum load this smart phone can last a maximum of 12 hours. If you reduce the load, you will get 2-3 days of confident work on one battery charge. If this is not enough, then we buy an additional external battery. Of course, this is not a very elegant solution, but your phone will not let you down at the most inappropriate moment.
Interface set
Samsung Galaxy S3 Duos boasts the presence of the following interfaces:
- “Wi-Fi” - fast download to your smartphone data from the Internet in any amount.
- GSM and 3G - with their help, you can download information from the global web, make calls and send or receive SMS.
- "GLONASS" and GPS allow you to accurately determine your location or get directions.
- NFC - this wireless interface allows you to download files of any size onto a similar gadget in minutes.
- BLUETUS allows you to do the same thing as NFC, but the amount of data should be much smaller.
- The 3.5 mm audio jack allows you to output sound from your smartphone to external sources of sound (speakers or headphones).
- With the help of micro-USB, the battery is charged. Also, this wired interface provides synchronization with external devices (PC, laptop).
Software
As the system software in this smartphone"Android" is used. Initially, version 4.3 is installed on it. But after the first connection to the Internet, the firmware of the Galaxy S3 Duos will be updated to a more recent version - 4.4. Further updates to the system software owners do not have to wait for this gadget. The smartphone has already been sold for a long time, and for quite a long time the manufacturer does not release updated software to it. On top of the operating system, as in any other device of this manufacturer, a proprietary shell TouchWiz is installed. You also need to allocate an impressive amount of pre-installed software. First of all it is "Polaris office". That is, this smartphone can immediately work out of the box with various electronic documents (* .doc, * .xls, * .pdf, and so on). There are also familiar programs from Google. Do not forget the Korean programmers and about social networks. Well, to top it off there is a full set of utilities built into the OS. So the smartphone out of the box is already completely ready for work.
The price of the gadget today
As noted earlier, on the background of directcompetitors cost a bit overpriced at the Galaxy S3 Duos. Its price is currently equal to 180 dollars. But, on the other hand, this can be justified by improved technical specifications. This is an increased diagonal of the display, a better organized memory subsystem, and a more productive computing platform. Therefore, the higher cost of this gadget is offset by a number of advantages.
Reviews
There are minor flaws in the Galaxy S3 Duos. Reviews highlight this:
- Glossy back cover.Such a constructive solution leads to the fact that on its surface is collected dirt and clearly visible prints. At the same time, removing them is quite difficult. A simple solution to this problem is to buy a silicone bumper cover. As a result, the surface of the cover will be reliably protected from various "harmful" effects.
- Small "glitches" in the software part associated with the work of two SIM cards at once. This problem manifests itself in the old version of the operating system. After installing all the updates it will not.
- Slippery surface of the back cover - because of this, you can accidentally drop the phone. Again, this problem, like the first, is solved with the help of a boot.
But the positive sides are much larger:
- Productive computing platform.
- Increased RAM and the capacity of the built-in drive.
- A good set of pre-installed software.
- Large enough diagonal display.
- The ability to control using gestures.
Outcomes
As a result, we get a great initial smartphonelevel with a slightly inflated price on the background of similar devices. But this minus Galaxy S3 Duos is more than offset by significantly improved specifications. This makes the purchase of this gadget more justified. You immediately receive from the box a ready-to-work device that does not need to be additionally filled with application software.
