Design and screen

The Samsung brought Note refinements to the project 4. While maintaining the same screen size, with 5.7 inches, the resolution brought an increase to 1440 x 2560, the QuadHD, compared to 1080 x 1920 (FullHD) the Note 3. With this increase, pixel density jumped from the house of 300 dots per inch to over 500, which means that the Note line to fight back in balance with top line Android devices this point.

Although debatable the difference FULLHD between QuadHD and in a compact space to the screen as a smartphone, the larger the display, the greater the importance of higher resolutions. The most obvious quality leap in this 5.7 “screen, as 380 ppi Note 3 approached the phablet the pixel density of the intermedirio smartphones segment.

the resolution QuadHD welcome on a larger screen, bringing the pixel density for a quality able to fight with the other high-end Androids

The Note 4 display has excellent color balance sheet and also to does very well in contrasts. On the brightness, luminescence of just over 300 nits in gets to be impressive compared to other models, but enough to see the contedos even in bright places.

Even keeping the size of the screen Note 3, Samsung reduced the edges on the side in 1 millimeter, porm increased when 2 millimeters. Despite being a difference “in detail”, narrowing the welcome side to facilitate time to hold the device the time of ergonomics, another difference is effective:.. the new metlicas edges While previous models brought a rounded shape, Note 4 brings a metal finish with more angled lines, which makes it the most secure fit in the hand .

ANALYSIS: Samsung Galaxy Note 4

Overall, the Galaxy Note 4 finish higher than the Galaxy S5. Although also be a plastic, the rear brings an effect that simulates leather, giving a more attractive appearance than the “band-aid style” smartphone line S. Another important shift in the edge of metallic style: it much less suscetvel peeling, and has more discrete lines.

Unlike the much criticized Galaxy S5, the finishes of the Galaxy Note 4 so neat and tasteful

Like any device through the 5 inches, the Note 4 in an easy machine to handle with one hand. Along with Zenfone 6, this unit came in the smartphone group was unable to use with only one hand – that I have long fingers – mainly because of accidental discharges in the boats of the base. Was trying alcanar the top of the screen, in addition to a complicated pulse game accidentally activated the button back on the base. Like many phablets, the Note 4 more comfortable if used with both hands.

Performance and autonomy

The Galaxy Note has two options chips: the Qualcomm Snapdragon 805 quad-core SoC operating at 2.7GHz (same Moto Maxx) and the model of our analysis, the SM-N910C equipped with SoC Samsung Exynos 7, a chip nuclei eight, four at 1.3GHz Cortex-A53-four Cortex A57 1.9GHz.

Despite being impressive imagine an eight nuclei smartphone chip. What we care system capacity and applications to exploit the component.

[BATTERY AUTONOMY: | SAMSUNG GALAXY NOTE 4]


How many phablets, the main advantage of Note 4 on the larger screen. With more available space, the manufacturers take the opportunity to caprichar on drums, and Samsung was the exception. The 3220 mAh battery in your s outweigh the 3900 Moto Maxx, and the result a great autonomy, prxima of devices with better performance in this respect.

In our practical test, with high consumption and all sensors 3G and constantly active, the Galaxy Note 4 managed to close a day of use and still endure a few hours the next day. Maneirando, we USED it comfortably for two days before needing to refil it.

Although the result is good, Sony follows the lead in this regard, stretching for almost three days the autonomy of Xperia Z3 thanks to a better optimized software. Considering the “stupidity” of battery that Motorola put, the difference between the Maxx and Note 4 in the very large autonomy in everyday use.

Note 4 able to hold a day with heavy use and all active sensors. Maneirando in use, it to have quietly two days of autonomy

camera

The Galaxy Note comes equipped 16MP with a sensor, and a focus hybrid system that combines both phase mode as a contrast. As a result, the fast and efficient smarpthone in time for the focus, especially by a characteristic of the Samsung software:. The smartphone is constantly testing the focus and exposure, even before usurio push to make the photo


Cmara Front

The Samsung smart software to the extent that checks the scene and seeks the best fit on their own. In dark scenes, for example, it the “calling out” the flash indiscriminately, and seeks to increase exposure to try to take a picture while maintaining the characteristics of natural lighting of the scene. The strategy works well in environments little busy, but just something to move or you do not stand firm to the device the picture is blurred. – Even with the help of optical stabilization

At the time of the videos, the device able to make images in 4K RESOLUTION, and image quality came with the level of quality of the photos, making great images and, thanks to the aid of optical stabilization, making recordings with quality even with a lot of movement.

A adding interesting camera software the ability to download new ways. There is a “configurations shop” for the photos in Note 4, which can be downloaded and thus bring new features like panormicas or photo in sport mode (with little exposure time).

Software and additional resources

The famous Samsung for its heavy intervention on Android. The relationship of love / hate with scrambled in comeam system by TouchWiz interface, which in of all evil, to insert useful things like sensors of the shortcuts in the Notifications bar and also a search engine, the “S Finder”. However, the ill-view Samsung’s interface to be considered responsible for a lower performance of the device and also take up much storage space

Note inserts two new sensors:. The button Home’re a fingerprint reader while at the rear, with the flash, the sensor is cardacos beats. Although interesting additions, I have my reservations in relation to them. Enough especfico digital sensor in the way you need to slide your finger so that it is recognized, which means that you must have to use both hands to unlock the device if you want to use as your digital security mechanism. To put it in perspective, the iPhone can identify the digital s touch with your finger on the button, which means that in a single gesture of pushing the button you can while unlocking the phone and also make the identification by biometrics. J with the Samsung model, the need to slide your finger to little practice it can at discouraging use this feature.

The sensor cardacos beats and digital are additions interesting but little practices

The rate sensor triggered through the app S Health, j shipped with the device and operating always in the background. Within seconds, the sensor can indicate the pace of cardacos beats, porm must keep your finger on the sensor and on the move a lot, which makes the process less practical to use a vestvel. Considering the size of the Note 4, it is also not a good companion for a jog or activity in an open environment, and the need to stop to see the rate decreases front practicality to more specialized accessories.

Besides the beats it capable of measuring the pulse oximetry, which represents the saturation of oxygen in the bloodstream. For exercises enthusiasts, this indicator in the valley very much worth: most healthy people are between 95 and 100% PO2S steadily, then measure this factor in service to track their evolution in fsicas activities. The measurements always Ficaro this house, unless you have some disease Respiratory. Below 80%, for example, already in their organs work more accurately.

Besides the sensor, the note 4 shows a series of Apps and embedded functions. The left screen last in the initial interface, j has built the Flipboad application, a popular organization app and reading contedos. Other applications “virtually obrigatrios” like Evernote, Facebook and Dropbox also are already on the device, which lay more interesting for users who prefer that the machine should “j ready” but that may displease those who prefer the device with more space disponvel and want to install only apps that will use.

The great line of differential Note the pen Stylus . Besides the great need, the Note has the great advantage j bring in your fitting design to keep her always available. To pull it, the j software identifies the use of accessory and opens a palette of options of what to do. The degree of need absurd, and even before touching the screen jh one marking where the pen is about to play. A secondary button also enables other interactions and again opens the pop-up menu, so being quite useful

Conclusion

The Galaxy Note 4 provides specific refinements with respect to Note 3, in terms of design. Its great advantage to larger screen resolution, which again brought the display to the level of the screens with better definition.

Overall, the Note 4 keeps the main features that make this device one of the leading sellers of South Korea: high performance, excellent screen, a powerful pen, good design and great battery duration . This combination makes this phablet the best model of larger dimensions disponvel market.

though, this model also retains the negative characteristics of Samsung on their smartphones. The system brings a lot of embedded thing and heavy modifications on the Android system. The same extent as it brings useful functions, also results in a lot of things you do not use and end up disabling. The sensors come in the same ballad, and the lack of practicality in using them far that most users simply ignore them.

{quote} The following Samsung resources without entering torn them efficient before. The result so sensors and features that you go disable or never use {/ quotes}

With a price of around R $ 2,800, this unit brings a very high cost. Models like the LG G3, which has a display only 0.2 “lower, can be found at the cost of R $ 1,400 and is should in no way compared to the model of Samsung in terms of specifications. The most important difference between the two models stylus, and unless you faa question of additional sensors or this accessory, the purchase of the Galaxy Note 4 can compensate in.
