When choosing Samsung products in a specialized store, I would like to have a clear idea of what the main characteristics, weak and strengths for the Samsung Galaxy S2 smartphone and the newer Galaxy S3 device. For a clearer understanding, let's do comparative characteristics these gadgets.
Appearance and dimensions
New device Galaxy S3 much more previous S2 (in height its size is 136.6 mm against 125.3 mm And in width – 70.6 mm against 66.1mm). At the same time, more old phone thinner and fits a little better in the hand. The cover material of the old gadget is made of a higher quality material that is not subject to scratches. The layout of buttons, USB ports and smartphone controls are approximately the same. 
Display
S2 has a display 4.3 inches diagonal and made using technology Super AMOLED Plus. Screen resolution amounts to 480x800 pixels. All these indicators are significantly weaker than those of new device, which more on 0.5 inches diagonally and has a more solid permission (720x1280). In addition, its glass that protects the display is slightly thinner and stronger. The color quality of the S3 is the highest possible at the moment. 
Memory
Both models are available in 16 and 32 GB variants external memory, But S3 has an option with 64 GB memory. Volume random access memory is the same and amounts to 1GB and, in addition, both gadgets have the ability to connect microcards that increase the memory capacity up to 32 GB. Thus, the capabilities of the devices here are approximately the same.
CPU
Although S2 and today has advanced dual core processor ARM Cortex A9 on the Exynos 4210 chipset, which copes well with running several programs simultaneously, however, S3 already installation announced 4 nuclear processor , operating at a higher frequency (1.4 Hz versus 1.2).
operating system
Both devices are firmware up to Android 4.0 Ice Cream Sandwich, however, the S3 has more serious equipment. So, for example, it has the following unique options:
— Smart Stay, allowing the device to respond to the owner’s gaze, turning on the display;
— S-Voice, which makes it possible to perform some functions (bringing the camera into working condition, taking the device out of standby mode, etc.).
Camera and speakers
IN new gadget camera is used from iPhone 4S (Sony module), and in old- from Samsung. The speakers in the devices are spaced in different directions, but the sound volume does not differ.
Accumulator battery
Battery capacity new device significantly more than the previous one - 2100 vs 1650 mAh, which allows it to work much longer. However, it is possible to purchase and install batteries with a higher capacity on an old device, which will only slightly increase the thickness of the case. The inconvenience of an old smartphone is that the micro SD card can only be removed after removing the battery.
conclusions
We can draw a definite conclusion that, based on the totality of characteristics new Samsung The S3 is superior to its predecessor, although it is not without some minor flaws (for example, in design) that do not affect the overall picture. More detailed information about the characteristics of smartphones can be found here.
Samsung's Galaxy S3 is one of the most popular smartphones 2012, but let's see how it will look in comparison with the new Galaxy S4?
We will compare the flagship in the line Samsung smartphones with its predecessor in this short review. The anticipation for the Galaxy S4 has been enormous and it has finally arrived. If you Galaxy owner S3 You might be wondering whether it's worth upgrading to a new model or whether you'll decide you'll save money by going with the well-reviewed Galaxy S3. We hope this comparison helps you make your decision.
We haven't had a chance to hold the Galaxy S4 in our hands yet, so this article is based on a comparison of the specifications of the Galaxy S4 and Galaxy S3, and of course based on our opinion.
Samsung Galaxy S4 vs Galaxy S3: Design
As you can see in the picture above, the Galaxy S4 looks very similar to the Galaxy S3 in terms of design. Simply put, it's just a larger version. The corners are also rounded, but it looks more square, in that it looks more like the Galaxy S2. Back cover is still removable, the “Home” button has slightly changed its shape. According to the company's specifications, the Galaxy S4 is marginally smaller than the Galaxy S3, despite bigger screen. The height is the same - 136.6mm, but the Galaxy S4 is narrower - 69.8 mm versus 70.6mm. It's also thinner and lighter than its predecessor - 7.9mm and 130g versus 8.6mm and 133g. An impressive effort from Samsung if these numbers are correct. 
Samsung Galaxy S4 vs Galaxy S3: Screen
The rumors are confirmed - the Galaxy S4 has 5 inch screen, meaning it will be slightly larger than the 4.8-inch display in the Galaxy S3. Both use Samsung's familiar SuperAMOLED screen technology. The size matches a lot of smartphones shown at CES this year, including Sony Xperia Z, Huawei Ascend D2 and ZTE Grand S. The resolution has increased from 720x1280 to 1080x1920 Full HD. Which significantly increased the pixel density from 306ppi to 441ppi.
Samsung Galaxy S4 vs Galaxy S3: Processor
Samsung used its own Exynos 4 Quad processors for the Galaxy S3 with a quad-core chip. It runs at 1.4 GHz and is based on ARM Cortex-A9 architecture. The Galaxy S4 beats it with the new Exynos 5 Octa processor that Samsung announced at CES. This is the first smartphone to boast an 8-core chip. It consists of four Cortex-A15 cores clocked at 1.9 GHz for core tasks, while the remaining four Cortex-A7s clocked at 1.2 GHz are used for less demanding tasks and power saving mode. RAM has also been doubled from 1GB to 2GB, so we expect the Galaxy S4 to come out on top in our tests.
Samsung Galaxy S4 vs Galaxy S3: Memory capacity
Samsung was generous with the storage space on the Galaxy S3 to match the iPhone's 16GB, 32GB and 64GB storage options, plus a slot for MicroSD cards. The situation does not change with the arrival of the Galaxy S4. So there is no reason to worry.
Samsung Galaxy S4 vs Galaxy S3: Cameras
8MP Galaxy camera S3 had quite standard resolution for 2012, with the exception of only a few phones. Samsung has equipped its Galaxy flagship S4 13Mp main camera and 2.1Mp front camera. This is marginally higher than the Galaxy S3's 1.9Mp, but it's important to remember that the Galaxy S4 can record video in Full HD 1080p, not 720p like its predecessor. We can't say whether the image quality is even better, but the stated specs already look pretty good.
Samsung Galaxy S4 vs Galaxy S3: Software
Samsung Galaxy S3 currently runs on Android 4.1.2 Jelly Bean, one of the most advanced versions in the Android world. The Galaxy S4 will come with version 4.2.2, there is no significant difference and both smartphones have Samsung's TouchWiz interface. The Galaxy S4 comes with new features including Smart Scroll, Smart Pause and Air Gesture. There are rumors that the Galaxy S3 will be adding some of the new features, but it's not clear which ones yet.
Samsung Galaxy S4 vs Galaxy S3: Battery
We expected the Galaxy S4's battery to be larger than the Galaxy S3's 2100mAh battery - and it is, at 2600mAh (both removable). Whether the battery life of the smartphone will be longer will become obvious when we carry out the right tests. Obviously, power consumption is greater since the screen is larger and has more a high resolution, but the Exynos 5 processor has power-saving cores that can make a big difference. (According to the latest information, deliveries of the Galaxy S4 with the energy-saving Exynos processor are not possible in all regions).
Welcome everyone to my blog again! This time we will do a comparison with you again, namely, we will compare the Samsung Galaxy S3 and the Samsung Galaxy S4. The object of our consideration will be their fundamental differences, as well as advantages and disadvantages. After analyzing all this, we will conclude which smartphone is better and which one is worth buying.
The question on this topic arose for a reason, it seems like I want to buy the latest new product, since most of us buy a smartphone for several years, but on the other hand, is there any point in overpaying!? Samsung is releasing updated smartphone models at an active pace, and if you buy the same S4 today, in a few months it will already be in the background. So let's find out whether it makes sense to buy S3 rather than S4 or vice versa.
In this article, I will not particularly focus on the parameters and features, but will only briefly go over their fundamental differences, both in terms of appearance and in terms of components. For a more detailed study of both models, I recommend reading my past reviews: Samsung Galaxy S3 review and Samsung Galaxy S4 review.
Comparison of Samsung Galaxy S4 and Samsung Galaxy S3
When comparing these two devices, you need to start, of course, with the parameters, and they are, in principle, quite different from each other.
Difference in technical characteristics
The Galaxy S3 has a quad-core processor with a clock frequency of 1.4 GHz per core, while the S4 has an eight-core processor with a clock frequency of 1.6 GHz per core.
As for RAM, the S3 has 1 GB, and the S4 has 2 GB. RAM memory is the same in both devices, depending on the model configuration.
The S3 screen is Super AMOLED, with a diagonal of 4.8 inches, resolution - 1280x720 pixels (306 ppi). The screen in the S4 is Super AMOLED HD, 4.99 inches diagonal, resolution 1920x1080 pixels (441ppi).
The S3 has an 8 MP camera, and the S4 has a 13 MP camera. As for video, it is the same for both 1080p gadgets.
The S3 has Android 4.0, and the S4 has Android 4.2.2.
The battery of S3 is 2100 mAh, and that of S4 is 2600 mAh.
Now let's summarize everything that has been listed. So, we see that the processor of the four is 2 times larger than its predecessor, the same goes for the RAM. And therefore, the new product will be 2 times faster than the previous model, which will certainly please those who are looking for the latest and most powerful Hi-Tech devices. Of course, we can’t help but say about the display, which from 720 has turned into 1080 pixels. This is a real paradise for lovers of watching movies on a smartphone, as well as for avid gamers. Good news for photographers: the quality of pictures on the S4 will be noticeably better than on the S3. Concerning operating system, then in the Galaxy S4 it is noticeably fresh - Android 4.2.2 Jelly Bean, while in the Galaxy S3 it is Android 4.0 ICS, forgotten by many. It is worth noting that a new version will be available for the Samsung Galaxy S4 Android firmware 4.4, but S3 will probably bypass such happiness, at least in the near foreseeable future for sure. For radio lovers, it is worth mentioning that the S4 does not have an FM receiver, so you will only have to listen to 3G radio and pay money for it.
Difference in visual characteristics
If we evaluate in general, then the design of two Samsung flagships almost the same: all the same placement of buttons, almost the same shapes and lines. If we study in more detail appearance two devices, they still differ in some details. S4 looks more solid and representative compared to S3. It is worth canceling the presence of a side frame on the S4, stylized as metal, which is not present in the S3. The new product is a little thinner than its predecessor, while weighing a little less, but if you take both gadgets in your hands, the difference in these parameters is not noticeable.
Well, we can’t help but mention the difference in price between the two gadgets. If we compare average prices, the S4 is 4,000 rubles more expensive than the S3, and this is a fairly significant difference, since with this money you can buy a 64 GB memory card, a case, and also top up your Internet account, and there will still be enough to buy necessary applications on GooglePlay.
Which is better to buy Samsung Galaxy S3 or Samsung Galaxy S4?
Having analyzed all of the above, we can conclude that there is no point in buying the Samsung Galaxy S4 as such. Yes, we should give credit to the manufacturers for putting together a super powerful model that has left its competitors far behind, but not all users need such parameters. In addition, if we analyze 2 devices from the point of view of innovation, then new model It doesn’t bring anything new except an upgrade.
Owners of the Samsung Galaxy S3 claim that the smartphone’s parameters are sufficient for them for all tasks, including working with resource-intensive applications and games. They note that the phone does not have the slightest freeze or slowdown, and therefore, why overpay money if the parameters of the S3 are enough for you. There's no point in overpaying for something you won't use in S4.
If you need a phone for status, and you plan to purchase a gadget for a very long time, then, of course, the most reasonable option in this situation is the Samsung Galaxy S4. Firstly, the latest models are always more prestigious than the previous ones, especially in the telephone world. Secondly, South Korean manufacturers, who have taken 2 steps forward, are giving Samsung Galaxy S4 buyers the opportunity to make a good investment in a promising smartphone that will be able to run modern programs and games in 2, or maybe even 3, years.
If you are the happy owner of a Samsung Galaxy S3, then there is absolutely no point in buying a new product. You will notice the difference in performance only in comparison, the same goes for the screen and camera. Otherwise there are no differences.
As for me personally, I preferred the Samsung Galaxy S4, because I like to test various games, programs and other “gadgets” of manufacturers, and this requires powerful components.
That's all. By and large, if you have an extra 4,000 rubles, then it’s better to buy S4, but if you buy S3, you won’t go wrong, since I didn’t notice any significant differences.
