Samsung sales started in May 2011Galaxy S2. The characteristics of its hardware and software parameters, reviews of the owners and other important information about this flagship smartphone will be discussed in detail later in this material.
List of accessories and components in the box
Characteristic phone Samsung Galaxy S2 withthe position of its hardware parameters at the time of its release allowed to attribute it to the flagship devices. But the bundle of this gadget is clearly not consistent with this fact. The reason here, most likely, lies in the fact that Samsung, like other manufacturers, focuses on Apple products, which sets the tone for the mobile gadget segment. Smartphones brand iPhone can not boast of a complete set of excellent. Here and with S2 a similar situation. The boxed version of this gadget includes:
- Smartphone.
- Battery.
- Charger.
- Manual.
No memory card, interface cable,a protective case and sticker and stereo headset and speech can not be. Although to do without any of the previously mentioned accessory, the owner of this device will be quite difficult.
Appearance
S2 has much in common with its predecessor -smartphone S, but it is not an exact copy of it. On the front side of the gadget displayed display, protected by tempered glass "Gorilla Eye". Above, above the screen, there is a front camera, sensor openings and a speaker. Below, below the display is a typical control panel. It consists of 2 sensory (located at the edges of the panel) and one mechanical (it is displayed in the middle) buttons. The lock button is located on the right edge of the device, and the rocker to adjust the volume level are displayed on the left side of the smart phone.
Located on the bottom of the smartphonemicrophone hole and the main wired port of the device - MicroUSB. On the top of the gadget, there is only one wired audio port. The back cover of the device is made of structured plastic. Here are the main camera with backlight, the manufacturer's logo and a loud speaker.
The processor and its computational capabilities
One of the best processors in 2011Used in the Samsung Galaxy S2. The characteristic of its hardware parameters allowed this chip to solve any problems in terms of complexity at that time. It is about Exynos 4210. This is a South Korean giant's own development. This CPU includes 2 cores of the Cortex-A9 architecture. Each of them could dynamically accelerate to 1.2 GHz at the highest load. If there was no need for such a high level of CPU performance, then one of the computing modules was turned off, and the second one reduced its frequency to 200 MHz. Such an engineering solution allowed to significantly save battery power. Samsung Galaxy S2 DUOS could boast of similar technical specifications. The characteristics of its processor are identical. But in this case, the MSM8660 chip from Qualcomm was used. The same can be said about the rest of the representatives of this family of smartphones: S2 Plus and S2 Mini. As a result, their performance level is comparable.
Gadget graphics
Fairly well implemented graphicsubsystem in samsung galaxy s2. The characteristics of the technical specifications of the graphics accelerator Mali400-MP4 are not impressive today, but its presence is enough to run most applications. The display diagonal, as noted earlier, is 4.3 inches. Its resolution is 480 x 800. Also, it is based on the matrix "SUPER MOLDED". The only thing that exactly causes complaints is the presence of an air gap between the touch panel and the screen surface. This leads to a distortion of the screen image with a significant deviation of the display from the right angle. Almost all devices in this series have identical technical parameters. The exception in this regard is the Samsung Galaxy S2 Mini. The characteristics of its display will be more modest. The resolution is exactly the same, but the diagonal is reduced by 0.6 inches and is 3.7 inches. Therefore, it will not be so convenient to work on it.
Cameras
Immediately, two cameras for shooting and recording video are equipped with Samsung Galaxy S2. Specifications they have so far mediocre, but onthe moment of the apparatus’s release, their parameters were among the best. The camera is based on a 8 megapixel sensor. Also at the program level, it implements the image stabilization system and autofocus. As a result, the quality of photos and videos does not cause complaints. And the developers have not forgotten about the LED backlight, which allows you to take pictures and record video even in the dark at a distance of 2 meters. A more modest sensor at the front camera - only 2 megapixels. But for video calls this is quite enough. Well, nothing more can be expected from it.
Memory
Despite the fact that in 2011 sales startedSamsung Galaxy S2, the characteristics of its subsystem even now, after 4 years, are impressive. The amount of RAM is 1 GB, and this wave is enough for normal and smooth operation of the gadget. Well, the capacity of the internal drive is 16 GB. Of these, 4 GB are occupied by pre-installed software. The rest of the user can use at their discretion. This is quite enough to install additional application software, and to store personal data (documents, photos, videos, music). There is also the possibility of installing an external drive with a maximum capacity of 32 GB. The corresponding slot is hidden behind the back cover of the device. It is possible to connect using the OZH cable (you need to buy it separately, it is not included in the delivery kit of the device) of a regular flash drive.
Autonomy
Very modest battery comes with this.smartphone. And exactly the same battery comes with the Samsung Galaxy S2 Plus. Its characteristics are identical to the flagship solution, but only the capacity of the built-in storage device is reduced by 2 times and equals 8 GB. The capacity of the battery is 1650 mAh. If we add to this a display diagonal of 4.3 inches and a 2-core productive processor that cannot boast of good energy efficiency, we get a completely bad situation with autonomy. At best, in the mode of maximum economy you can stretch for 1.5 days. If you increase the load on your smartphone, you can count on 1 day of work. Well, if you make a call, one battery charge is enough for half an hour of communication. You can solve the problem of autonomy by buying an additional battery with increased capacity.
Communications
Perfect communication kit in S2. It has everything you need to start using the device fully immediately after purchase. The list includes the following:
- Full support for mobile networks of the second and, of course, the third generation. В первом случае теоретически можно получить data rate of 450 kbps. In practice, this value is substantially less. But in the case of work in 3G networks, the speed can theoretically reach 21 Mbit / s. In reality, as in the previous case, the speed will be less.
- The main wireless interface is Wi-Fi.. Almost all its modifications are supported,except "ac". This standard appeared much later and therefore is not implemented in this device. The maximum speed in this case can theoretically reach 150 Mbps.
- Do not forget the developers and about such an importantwireless way to get information like bluetooth. It is indispensable in cases when you need to transfer or receive a small file from a similar mobile device or connect a wireless stereo headset to your smart phone.
- To navigate, the device is equipped with a GPS sensor and A-ZhPS system.. Integrated use of these two componentsallows you to accurately determine the location of this gadget. Also, with their help, it is not difficult to turn this smartphone into a ZHPS-navigator.
- There are only 2 wired interfaces in this device: MicroUSB (battery charging, PC connection) and audio port for connecting headphones.
A similar communication set is implemented in other smartphones of this series, for example, in the very Samsung Galaxy S2 Plus. Their characteristics are practically identical in this respect.
Software
As system software inThis family of smartphones is the most popular platform today - “Android”. And in the initial state version 2.3 is installed. But when you first connect to the Internet, the software will be updated, and the OS version will already be 4.0. On top of the operating system, the TouchWiz version 4 shell is installed. With its help, you can easily reconfigure the interface of a mobile gadget strictly to fit your needs. The rest of the set of software is standard: social services (only international, and their domestic counterparts will have to be additionally installed from the Playmarket), mini-applications from the OS, and a set of programs from the search giant and part-time operating system developer Google. .
User Opinion
Samsung is a very balanced solution.Galaxy S2 i9100. His characteristics clearly confirm this. The processor, the memory subsystem, the display and the graphics accelerator are all perfectly matched, and there are no problems with this. Also, cameras allow you to receive photos and videos of acceptable quality. But with what problems have the owners of this gadget, so it is with autonomy and accessories. The battery capacity is really modest, on one charge, as noted earlier, you can stretch a maximum of 1.5 days. This problem can be solved only by buying an extra battery for extra money. Similarly, you can solve the problem and modest configuration. If you need a stereo headset or interface cable, then buy it separately for an additional fee. And in this case, the accessory is chosen exactly what is needed, and not an economy option from the manufacturer.
Price
One of the most expensive smartphones at the timeAppearance on sale was the Samsung Galaxy S2. Specifications made it the best solution among the "Android" gadgets. Accordingly, the cost he was about 800-900 dollars. But now, after 4 years, its hardware and software specifications allow competing only with entry-level devices. Accordingly, the cost of it dropped to 150-160 dollars. This price makes it one of the best deals in the segment of entry-level devices.
Outcomes
Over 4 years of sales, smoothly dropped from the segmentpremium smartphones in the entry-level niche Samsung Galaxy S2. The characteristic of its hardware resources clearly indicates this. But, on the other hand, even now, most everyday tasks can be easily and simply solved on this device. Not every gadget boasts such performance.
