What is the screen resolution of samsung galaxy s2. Comparison Samsung Galaxy S3 VS Samsung Galaxy S2

General characteristics

Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to choose a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

After the stunning success of the already sensational smartphone Samsung Galaxy S, where demand exceeded supply. No one in the company expected the “galactic” model to be such a success, which caused problems and disagreements within the company. The main problem with the shortage of phones in many markets was the shortage of SuperAMOLED screens. Given the huge demand, the company took a rather interesting step, namely, it launched a similar model on the market - the Galaxy S i9003, but with a SuperClear TFT display, which is inferior in many respects. Model i9003 became 100 euros cheaper than the i9000, which made it quite popular and in demand. Despite the simpler display, all other parameters remained unchanged and the younger model was considered one of the best smartphones of its time.

Samsung Galaxy S2 has become a worthy opponent of the iPhone 4, but they are not yet fighting on equal terms, but there is still a long way to go. This smartphone has a huge number of latest technologies, for example, this is the first phone that supports Wi-Fi Direct and does not require special software to work with a computer. The phone can send files via Wi-Fi and has a range of additional programs, which has no analogues in other Android smartphones, but which will soon become standard. It would take a long time to list the technologies used in this smartphone (NFC, MHL, and so on), there is an impressive number of them. Without unnecessary words we can say that Samsung created a flagship phone and did it without wasting money. As a result, we received a first-class smartphone with great prospects and opportunities. They managed to create great phone price/quality comparison.

Design and appearance

Considering the amazing success and high sales, Samsung decided not to change anything in the design, with the exception of the size and thickness of the smartphone. For some people this may seem strange, because people expected a change in the design, although on the other hand, “the winning line-up is not changed” and they decided not to change the design. Since the display has become larger, the phone itself has become wider, but at the same time thinner, in the end we got an amazing 8.49 mm thickness. The trend of ultra-thin phones is back after 4 years.

The case, like the Galaxy S, remains plastic, the only difference is higher quality plastic. The plastic is not easily soiled, it doesn’t leave any traces, it doesn’t get tangled, but for that kind of money I would still like to hold a smartphone in my hands in a better quality case, ideally it would be a metal case. The plastic looks fragile and thin, but in practice the case turned out to be quite high quality and durable.

This smartphone is uncomfortable for the hand, especially for girls, as it hardly fits in the palm, which causes a lot of inconvenience, especially in transport or in winter when wearing gloves. When purchasing, you should first hold it in your hand to understand whether it is suitable for you. The dimensions of the phone (according to official data) are 125.3 x 66.1 x 8.49 mm, with a weight of 116 grams.

We talked about the appearance, but a few words about the keys and connectors are worth mentioning. The buttons are located similarly to its predecessor: one button to return to the desktop, as well as a volume button / camera zoom button and a button to turn on / off the smartphone. Among the inconveniences, one can highlight the absence of a camera call button, as well as mechanical buttons return to the previous menu and buttons for calling the context menu.

At the top end there is a 3.5 mm headphone output, a microUSB connector is located at the bottom. On the back surface there is an 8-megapixel camera lens, as well as an LED flash, and a speaker is located at the bottom.

Settings, menu

Samsung smartphone Galaxy S 2 runs the operating system Google Android 2.3. A proprietary shell works in tandem with the popular operating system. TouchWiz 4.0.

To start working with your phone you need to unlock it, for which you need to pull down any point on the screen saver, after which you can launch required applications And . The application menu is the same as on all Android smartphones. All programs are collected in general list with the ability to view the entire list. For user convenience, there are 7 desktops, each of which can be customized. To navigate between desktops, you need to scroll from left to right (it’s the same in iOS), which is not very convenient. If you scroll from right to left, nothing will happen.

Among the advantages of the TouchWiz shell are large and clear interface elements. This is very convenient, it is almost impossible to “miss”, which will be useful for people with vision problems.

The second most important advantage is the fast and convenient scrolling of pages with one touch.

When you enter the phone menu, a small number of widgets and application shortcuts catch your eye. The most important of them: Google search, clock, settings, weather forecast and much more. The menu also includes AP Mobile news, photo frame, quotes, Social Hub, Music Hub, Readers Hub, Game Hub. List of additional Samsung Galaxy S2 Software no different a large number, but still all the basics are there.

Samsung Companyg made a rather interesting attempt to provide its users with everything they need, for which the Hub tool was invented.

Readers Hub unites 3 online literature stores under one wing: the Kobo bookstore, the Zinio magazine store, and the PressDisplay newspaper and news store. You can download 7 newspaper issues for free from PressDispay and some books that are in the public domain. You cannot download magazines without registration, and after that - only for money. Social Hub is an application that brings together clients social networks, mail, blogs, as well.

The third hub is music. Essentially, this is a music store (the store contains works from the region where the smartphone was purchased). Here you can track the popularity of songs, view information about the artist, his tracks, and also buy the melody you like. It's essentially a music store.
Game Hub is a store for games recommended by Samsung. In essence, this is the same Andoid market but exclusively dedicated to games.

Display

Smartphone Samsung Galaxy S2 equipped with the best of the best (at the time of its appearance on the market) display - SuperAMOLED Plus. Many skeptics may think that this is just another marketing ploy, but this is not the case at all. New display brighter, sharper, but also more economical. Now appeared additional customization– adjusting the level of screen power consumption, depending on the picture used and the colors that are currently displayed. This technology is actively used in all modern Samsung TVs. A separate processor is capable of analyzing information and improving the quality of picture display, which makes using the phone very bright and colorful.

In the sun SuperAMOLED Plus the screen behaves a little worse than in first Galaxy S, the explanation is that the size of the matrix has increased, but the resolution remains the same, plus the technology has changed. The picture is readable at right angles or in not very bright sun. Otherwise, everything was done conscientiously and raises no complaints.

The new display brought a couple more pleasant moments: the user now has the opportunity to select the picture saturation mode. Three modes have appeared: Movie, Standard and Dynamic. Practical use showed that the Movie mode can be considered the most optimal mode.

The main advantages of the display of Samsung's second galaxy smartphone are the screen diagonal - 4.3 inches, resolution - 800x480 pixels and 16 million colors. In practical terms, the display is very convenient; there is automatic brightness adjustment. Safety glass tempered, coated with anti-reflective material, the screen also does not get dirty with your hands.

Camera

Samsung Galaxy S II has two cameras on board: the main one and the secondary one. The main camera is located on the back panel of the hero of our review and has a resolution of 8 megapixels. The additional camera has a resolution of 2 megapixels and is located on the front panel. The main camera takes pictures with a maximum resolution of 3264x2488 pixels and records video at 30 frames per second in MP 4 format with Full HD resolution.

One of the disadvantages is the lack of a separate key to control the camera, this makes it difficult to carry out various operations with it. The video and photo recording program launches in a split second from the main menu. Pictures are taken quite quickly: setting up the flash and autofocus will take about 1 second.

The camera control program is easy to master due to the program interface that everyone can understand. On the right side of the display there are large shutter buttons, a mode switch from photo to video shooting and vice versa, below is a small image of the last photo taken. By clicking on a photo you will immediately be taken to the photo album. On the left side of the screen there is a flash control button, a switch between main and additional camera and a button to call the main settings menu. The menu for the main camera settings is not very convenient; after pressing the button, a long list appears, which you need to scroll for a long time to get to the desired item. The list of camera settings looks something like this: resolution, autofocus operation (automatic, macro, face detection), shooting mode, image quality, effects (negative, sepia, grayscale), exposure compensation, timer, exposure metering, flash operation, stabilization, ISO, balance white, GPS tags.

By using Samsung Galaxy S II can be done enough high quality photo and remove good video, compared to photographs taken digital cameras compact class. Thanks to the large volume internal memory communicator, if necessary, its owner can quickly film something interesting happening around him.

Battery life

The powerful dual-core processor and bright AMOLED display in the Samsung Galaxy S II, the same as in the HTC Sensation, raised doubts about the portability of the communicator. Availability of capacious battery(1650 mAh) could not dispel doubts regarding the sufficiently long battery life of the device.

But tests of the GalaxyS II battery life showed that in audio player mode with the screen turned off, it worked for 19 hours, in e-book with average backlight level – 12 hours. With a video running, wireless interfaces activated, and the backlight at maximum, the Samsung Galaxy S II worked for 5 hours on a single battery charge. In normal mode: networking, SMS, several voice calls, working with Wi-Fi turned on, the communicator was discharged within a day. The battery is fully charged in 5 hours. With increased load in the area of ​​the main camera lens, the communicator gets very hot.

Samsung Galaxy S II does not hold the record for battery life. Compared to HTC Sensation Hero this review It works a couple of hours more in audio playback mode and a couple of hours less in e-book mode. In general, modern mobile computers time autonomous work not much different from each other.

In the settings menu of the Samsung Galaxy S II there is a special item that is responsible for detailed configuration of the communicator’s battery operation. For example, depending on the remaining battery charge and the owner's needs for present moment, you can adjust the screen brightness and wireless communication modules.

Conclusions

Samsung Galaxy S 2 can currently be called a unique communicator in many respects. If the filling of modern communicators is approximately the same: powerful video accelerators and dual-core processors, then the bright Super AMOLED Plus display in light thin case - this is a distinctive feature and an absolute advantage of the Samsung Galaxy S II.

The disadvantage of this communicator is that the design is too simple, unattractive and monotonous. But this drawback is overshadowed by the included display; against its background, the unassuming shell does not catch the eye.

The conclusions regarding the future of the Samsung Galaxy S II are obvious - this is the future flagship of the Samsung line and, until the appearance of its successor, it will remain one of the most powerful communicators on the Android platform on the gadget market.

Today, if you do not pay attention to the appearance of the device, you can get a standard communicator of 2011 in terms of both hardware and software, capable of competing on equal terms with the iPhone of not only this, but probably the next generation.

Form:

Samsung Galaxy S3 - 136.6 x 70.6 x 8.6 mm. Weight 133 g.
Samsung Galaxy S2 - 125.3 x 66.1 x 8.5 mm. Weight 116 g.
What can we say about design? The Galaxy S2 was the most memorable smartphone of 2011, different from anything else on the market. His visual style has become iconic, which feels a bit like an ongoing trend Apple in iPhone production. Recognizable angular shape with rounded corners, the thinnest profile with a thickness of only 8.5 mm. Even after a year, it remains stylish, despite the already changing trend of changing shapes. Chrome inserts perfectly set off the overall black profile of the device, which is not so noticeable in the white version. Back cover The battery is made of textured plastic, comfortable to use.

We can talk a lot about quality, but I’ll still note that in a year using Galaxy S2 remains just as strong. This distinguishes it from all competitors - it is actually a premium and flagship device. There is no cheap feeling in your hands that can appear when you hold the Samsung Galaxy S3 in your hand. Surely, when used, the SGS3 plastic will not perform at its best.

If we return to the design again, the shape has become completely different. Galaxy S III is more like HTC One X or even Galaxy Nexus, but definitely not like its predecessor. However, I dare say that the Nexus looks prettier compared to the Galaxy S3. But this is a personal opinion.

SGS3 was also made in two color options - blue and white. We won't see classic black this year, which is quite unusual.

Like the previous generation smartphone, the Galaxy S3 has additional physical button"Home" and capacitive "Menu" and "Back" buttons. That is, Samsung decided not to abandon the complete transition to touch control.

By the way, in conclusion, a few words about the plastic of the SGS III - for some reason, the production used not matte plastic, like HTC's, but glossy. You can imagine how easily soiled it will be even with short-term use. It feels quite cheap and “sticky” to the touch. It may look attractively shiny in the advertisement, but you can imagine how much marks will be left on it after a day of work.

However, one could expect improvements from Samsung in terms of the evolution of the Galaxy S2, but everything only got worse and caused a lot of criticism after the presentation on May 3.

That is, it turns out that by design new Galaxy The S clearly doesn't qualify as a new flagship, while the Galaxy S2 still evokes only positive emotions. Even in terms of build quality, the SGS II has no equal.

Display:

I'll start with the Galaxy S2 - it received a 4.3-inch display from Samsung, made using technology Super AMOLED Plus, protected by durable Gorilla Glass. Its resolution is standard for 2011 flagships - 480x800 pixels, which gives a dots per inch density of about 217 ppi. Of course, this is not the best quality for displaying images, but it still remains among the best in terms of color saturation, contrast and brightness.

Samsung Galaxy S3 has made significant progress compared to its ancestor. With a fairly affordable case size, the manufacturer was able to “shove” a 4.8-inch diagonal screen into it. That is, with a slight increase in the size of the case, the size of the display has increased quite significantly. Not only that, SGS3 already has a display with Super technology AMOLED HD 720p, which greatly improves image quality.

With a resolution of 1280x720 and its diagonal, the density of dots per inch was about 306 ppi. For such sizes this is very, very good. Moreover, even the screen protection has already improved by an order of magnitude - durable second-generation Gorilla Glass is used. It is not only stronger than simple Gorilla Glass, but also thinner, which generally affects the overall thickness of the smartphone.

In terms of color depth, brightness and contrast, no display with a density of over 300 ppi can yet become an alternative to SGS3. Although these are only written characteristics, which are difficult to evaluate by eye in comparison with other slightly worse competitors. When purchasing, this may not be a significant factor that will influence its purchase. The only surprising thing is that, despite its rather not gigantic dimensions, it has a huge display.

It's clear that the Galaxy S3 is superior to its predecessor.

Memory:

When is it usually considered inner filling Samsung smartphones, then there is a very large selection and opportunity here. This applies to both internal and external memory. Galaxy S2 and Galaxy S3 are available for sale in several versions - 16GB, 32GB, and SGS3 even has a model with 64GB of memory. All of the listed models have 1GB of RAM on board and an additional slot for connection microSD cards up to 32GB.

It turns out that the Samsung Galaxy S3 is not very different from the Galaxy S2. There is still the same choice of models, although expanded to include an option with 64GB of memory.

CPU:

Samsung Galaxy S2 was ahead of its time in all respects in terms of technical stuffing. He is still doing great against his competitors. Many current smartphones still cannot reach the level that SGS II set. The heart of the smartphone is dual-core ARM processor Cortex A9 on the Exynos 4210 chipset, which runs on clock frequency 1.2GHz with support for Mali-400MP GPU. As a result - overall speed working in applications, demanding games and running several programs simultaneously. Excellent results in multitasking.

Today, the Galaxy S3 became the first announced smartphone with a quad-core processor, which is about to go on sale. Let there be ARM Cortex A9 again, however, this is a new chip with four Exynos 4212 cores, which is better known as Exynos 4 Quad, operating at 1.4 GHz. Still helps him GPU Mali-400MP, which has proven itself very well on the Galaxy S2 platform and Galaxy Note. Quite an expected decision for the manufacturer.

Apparently this ratio of processor work and graphics chip puts Galaxy S3 at the top of the results tables synthetic tests. According to rumors, it will be more powerful than the popular Nvidia Tegra 3.

Operating system:

Now you can seriously argue which smartphone is better, since just recently the Galaxy S2 also received an update to Android 4.0 Ice Cream Sandwich. It turns out that both smartphones work on the same platform, which is hidden in the Samsung shell – TouchWiz.

However, it is worth noting the Samsung Galaxy S III, which is more seriously equipped. I won’t go into detail about its unique options, but I’ll just briefly list some interesting ones:
- Smart Stay, which allows the smartphone to quickly respond to the owner’s gaze, turning on the display only when they are looking at it;
- S-Voice, allows you to control a large number of functions using your voice (activating the camera, waking up the smartphone from standby mode, etc.) and others.

It’s probably too early to evaluate these possibilities, since the Galaxy S3 will appear on storefronts only in a week. However, they will still be a clear advantage over other smartphones, including the Galaxy S2.

Camera:

It’s quite difficult to determine a clear winner here, since both smartphones are equipped with an 8MP camera with a backlit matrix and a resolution of 3264x2448 pixels. There are also general functions - geo-tagging, autofocus, LED flash, touch focus, image stabilization, face and smile detection. Both cameras also shoot video at Full HD 1080p resolution.

The difference between SGS3 and SGS2 is that additional options: This is how the camera on the Galaxy S3 can simultaneously shoot video in Full HD and take photos at the same time. The SGS3 can also shoot 3.3 frames per second and select best shot among a series of 20 frames. If you wish, you can even enable the function of recognizing friends' faces in photos and sending pictures to the network with adding tags. The Galaxy S2 has an option for video lighting.

Both smartphone models have front camera– for S2 it is 2MP, and for S3 it is 1.9MP, with the video recording option active. True, in SGS3 the camera can shoot video in high resolution 720p HD.

It turns out that the Galaxy S3 acquired a camera with best quality and wide possibilities.

Battery:

Samsung Galaxy S III has a battery with a capacity of 2100mAh.

Samsung Galaxy S II has a battery with a capacity of 1650mAh. Its characteristics: standby time up to 710 hours when working on a 2G network, up to 610 hours when working on 3G networks; talk time – up to 18.3h/8.6h in 2G/3G networks.

Results:

Now we still need to say whether the Galaxy S3 is better than its predecessor. But here’s the problem: it’s both better and in some ways worse. If we consider only the power, display and camera, but without words of objection I can say that the Galaxy S3 has moved forward. But on the other hand, it is impossible to unequivocally judge the “intelligent” functions that were introduced into SGS III. What can I say about the design? In my opinion, the Galaxy S3 cannot in any way be considered a premium toy; its design not only evokes mixed emotions, but is even repulsive.

By the way, for “sweets” I decided to add visual table, which, like nothing better, will show the evolution of the Galaxy S line. It is quite clearly visible that from model to Samsung models All technical parameters were finalized.
