The maximum brightness of the screen of Samsung Galaxy Alpha was 327 cd / m 2, but it is a white pattern in the entire area of the screen. In fact, the brightness of the white color varies depending on the area (average brightness) of the image, and with a decrease in the area of brightness reaches a higher level of 362 cd / m 2. Therefore, the lack of real images in brightness was observed. On the contrary: through the stunning contrast of the screen with self-illuminating pixels of OLEDs image looks rich, deep and legible in all lighting conditions. In this respect, OLED-displays are simply unbeatable. Help and improved anti-reflective properties, is saved from direct exposure.

It is interesting that Samsung continues to improve some aspects, for example, in the current model viewing angles suffer from some "tuning", resulting in lost bluish offset at an angle. Hardly distorted image, except that a limit angle - about 180 degrees - by the screen can be seen "rainbow" overflow, which indicates that a specific polarization. It seems like you can wait and upgrades to future models with screen Super AMOLED. Gamma curve of the screen Samsung Galaxy Alpha are close to optimal and the average value - 2.24. In practice transitions brightness in shadows and light areas are being worked out perfectly, giving the image clarity and depth.

Color, as usually depends on the chosen screen mode. Here are a few to choose from the options: "Main", "Photo AMOLED” and “Film AMOLED". Mode "Adaptive Display" uses different color profiles as needed, but support is available only in certain applications. "Basic" mode combines the best color settings: flat neutral tone image with the average color temperature of about 6500K and a color gamut close to the standard sRGB.

Mode "Photo AMOLED" - is an attempt to simulate the extended color space Adobe RGB, which is sometimes used by professional photographers. This time attempt is good: green (which is the main difference Abobe RGB and sRGB) shifted slightly in shade, but otherwise good accuracy, including the intermediate gradations. Excellent color balance: as in "basic" mode, the deviations here are quite low. This mode is well suited to those who want to see the image with the "sweetened" saturated colors without compromising the overall balance.

To summarize, there is nothing left but to praise the screen. Mobile screens OLED finally got rid of the roughness and deservedly won a high place in ranking. Samsung Galaxy Alpha again showed excellent brightness characteristics and decent color accuracy, but this time it is still worth noting improved viewing angles and anti-glare. But the main thing is something that is not always possible to measure formally. The image looks really deep and realistic, with a very fine study of shadows. There is no doubt that the screen will be able to meet the needs of any user, regardless of the preferences - whether it's accurate or vibrant colors. This is one of the best screens, which can be found in mobile devices. And Samsung will keep this thing in upcoming phones too, for example: Samsung will power Galaxy S7 with such display but with more resolution.

For the small screen diagonal of 4.6 inches in Xperia Z3 compact feature resolution HD - a reasonable solution. For clarity and contrast of the image on the Z3 Compact is not inferior to actual flagship of Xperia. The compact device can boast the same proprietary image enhancement technology: limiting brightness mode and X-reality.

Compared with faded displays of Xperia of previous years, IPS-matrix system - a giant step forward. Claims to the quality of an image or viewing angles, they’re except that the prejudice against users of Sony products. Now the device has oleophobic coating: abrasions and stains on glossy glass pane great spoil the impression from the sight of a miniature flagship device.

The new Xperia Z3 compact is working on Snapdragon 801 quad with a maximum clock frequency of 2.5 GHz and Adreno 330 graphics system - similar to "stuffing" and equipped with the flagship Z3. However, without simplification characteristics still not done: RAM reduced from 3 to 2 GB. On the built-in storage space provides 16 GB and expandable to 128 GB with card microSD. The vendor has cut the battery life: mini flagship has a battery capacity of 2600 mAh, but the screen is small with low resolution and competent optimization done their job - a smartphone can really hold out for two days with average load, as the creators say.

While the gadget runs on Android 4.4.4 KitKat, “decorated" brand shell having little in common with the classic version of the operating system from Google. Most likely, Lollipop update will bring the significant changes. The device does not beat performance records in synthetic tests, but demonstrates excellent results similar to Oneplus One and HTC One M8. Much more important are the impressions of the operation: Xperia Z3 Compact interface scrolls smoothly, problems running applications or games smartphone does not occur. Intensive arcade make glass body evenly heated, but it is not critical - in this state it iw still comfortable to use.

Here, the manufacturer did not make concessions: Z3 Compact Camera takes pictures with a maximum resolution of 20.7 megapixels. Exmor RS CMOS module takes no worse than in the flagship Z3. Another issue is that if we evaluate the latest generation of camera phones like Xperia - diagnosis will be disappointing. If the owners are dissatisfied with color and deep shadows in the images, the mass of "entertaining" photographing mode will help smooth out the experience.

A small device with Android but it is not the most productive and still worth of the processor and screen of five inches. It is convenient to use Sony Xperia Z3 Compact because of its size. And this year also we might see the launch of Sony Xperia Z5 compact launch.

The most important thing for us is the sound quality of the phone and Huawei Ascend G7 did not disappoint. The sound level of phone is like any other modern smartphone. As the player use proprietary application the Music, the player interface is minimalistic. All covers are cut to circular tracks on the basis of the status of the entire system. Of the additional effect of the presence mode is only DTS (Digital Theater System). In the settings you can activate the timer, after which the player automatically turns off.  It is useful thing for those who like to sleep with headphones. Officially supports the following audio formats, MP3, MIDI, AMR-NB, AAC, AAC plus and more. With regard to support Video, the smartphone out of the box can play the following files MPEG-4, H.264, H.263 and more.

The smartphone has a removable battery at 3000 mAh. This is not a record, considering the possibility of capacitive latest innovations, but the real figures are impressive run time. G7 calmly can work in the mode of a heavy load for full two days in a row. Under heavy load in this case, 2 hours on the day of the Internet through Wi-Fi, the creation of about 40 pictures with the main camera, constant background push-notifications from various applications, correspondence through Viber, two hours reading e-books and so on. Most charge ate, of course, the screen. Second place is shared between a bond and the system.

Given all this, Ascend G7 can be easily considered one of the best smartphones to date, in terms of energy optimization. You don’t need to charge it every day. If we use proprietary power-saving tweaks, you can get even more interesting results of autonomy. For example, there are several modes of consumption of battery life: casual, smart and extreme. Last transforms your smartphone into a black and white dialer with the function of SMS messages, but allows you to stay in touch for some time. According to the manufacturer, with 10% of the remaining battery capacity can hold for about 24 hours. Approximate forecast save battery system provides the settings of real-time.

It was about the recent Ascend G7 phone from Huawei. If you remember last Sep, Samsung unveiled the Note Edge device with unique display and similar for this year, Samsung would be launching Galaxy Note Edge 2 and on other hand, Huawei has similar plans to launch similar kind of device.

When it comes to the premium tablet of the market, then just two names would come in the front one is the iPad series of Apple and second Galaxy Tab S of Samsung. The most recent member of iPad series is Apple iPad Air 2 which was one of the slimmest and lightest tablets at the launch and later Samsung followed the same path and launched the Samsung Galaxy Tab S 10.5. If we compare the dimensions, both the tablets have the tough fight but being lighter Samsung wins the race.

In terms of display, Samsung has fitted the 10.5 inches screen in the Galaxy Tab S 10.5, which is itself veridict as it is using the technology Super AMOLED. Well, lots of fans were waiting to see this technology in 10.5 diagonal size. Although both the tablets has the high-end resolution but aspect ratio of Galaxy Tab S makes it verdict.

Apple iPad Air 2 is powered with the latest and improved finger print scanner which works like charm and on other hand, Samsung is following the path when it comes to the finger print scanner and it needs lots more refinement. Similar thing happened with the Samsung Galaxy Tab S 10.5, the tablet is powered with the fast finger print scanner but in this war, Apple is ahead with the Apple iPad Air 2. But you can expect Samsung to improve this with the upcoming launch of new member in the same series.

The battery life of both the devices is almost similar but Samsung takes the lead with Samsung Galaxy Tab S 10.5 longer battery life and associated energy saving modes. It was all about the war between Samsung Galaxy Tab S 10.5 and Apple iPad Air 2 and the war would not end here. In many aspect Apple iPad Air 2 is ahead, even it is cheaper in price in many of the countries but it could matter of your taste for operating system that which you want to choose between iOS or Android. Both the OS are the most flexible but the most used is Android for no doubt.

These two tabs belongs to high end market of tablet and soon a cheaper solution is about to launch by Samsung in the Android market so called Samsung Tab 5 and on other hand Apple has the different plans and it is even discarding the cheaper series of Apple iPad Mini.

The new Note 4 comes with the better-designed and functional S Pen. What is important, S Pen can determine the force pressing the stylus on the screen and display a small circle in the display space of contact when approaching the tip at a distance of about 2-3 cm from the screen. This ensures a high positioning accuracy and allows much more convenient to write or draw a line. In this regard, S Pen is well ahead of the active stylus for devices from other manufacturers that do not have as much tighter integration with the operating system.

If handwritten notes, annotations and collecting clippings all clear that many are interested in what it is for sure, draw on your smartphone. No matter how technologically is working behind pen S Pen, expect a serious picture is not worth it. Many professionals are also playing the S Pen to draw things. But the verdict was not in favor of Samsung: you can draw for fun, but about something serious, however. However, the mobile device is designed for quick sketches, drawings and notes on the go, and this Note 4 copes fine.

In terms of camera there were no surprises in Note 4, a module is installed, similar to Galaxy S5, that is, 16-megapixel own production. The only difference is the presence of optical image stabilization that produces the characteristic tapping by shaking your smartphone. The rest is the usual proportions 16: 9 picture, the pixel size of 1.12 microns, F / 2.2, the focal length of 31 mm - equivalent to 35 mm. The photos are of excellent quality, the focus instantly. One can find fault except for night scenes, where the leader was still with it, Nokia camera phones such as 1020 and other top models.

The camera interface has not changed compared to the Galaxy S5 and its main drawback is part worth - too many tools and options that can scare people are far from the photos. However, the manual values ​​ISO, exposure, white balance and changing modes of change - is voluntary, so that the camera can be great to use on a "fire-and-shoot". The manufacturer is not obliged to delve into the settings to get good photos.

As for the front-facing camera for selfies lovers, the resolution has been increased to 3.7 megapixels. It is less certain devices on the market, but enough to get good photos. When you switch on the front of the camera has a couple of interesting features. Firstly, it is touching the shutter pulse sensor, and secondly, the ability to take wide shots to fit on a single photo of large group of people. In this case, the mode is activated, such a panorama, the user must hold the device from side to side.

The Galaxy Note 4 is one of the revolutionary gadgets Samsung ever created and Samsung will keep it in the Galaxy S series also, and we are expecting serious changes in Samsung Galaxy S7.
