Tablet Samsung Galaxy Tab S4 10.5 SM-T835 64Gb - advantages and disadvantages

In 2018, Samsung unveiled the Samsung Galaxy Tab S4 tablet.

Samsung Electronics is a well-known company and therefore the popularity of its models is beyond doubt. She is constantly fighting in the ratings of high-quality and functional devices with Apple for the laurels of primacy. And, undoubtedly, these are the best manufacturers of electronics and all their new items are popular models that are of great interest. Galaxy Tab S4 10.5 SM-T835 64Gb is no exception, but could this Samsung device beat the competition?

Equipment

The box contains the main set, the advantage of which is, like the Tab S3, the presence of a stylus, unlike Apple, where it must be purchased separately:

• the tablet;
• cable (USB Type C), cord length - 120 cm;
• adaptive charger - 2 A;
• stylus;
• documentation.

For a fee, this set can be supplemented with a keyboard case and stand case.

Appearance

At first glance, the Galaxy Tab S4 appears to be identical to the Galaxy Tab S3, but there are slight differences. The dimensions of the tablet have slightly increased and are 249 * 164 * 7.1. Device weight - 483 g.

Materials of which the body is made: on both sides - tempered glass, framed by an aluminum frame. It is not very clear that there is such a fragile material on the back, as there is no wireless charging. In addition, the assembly is not sealed and does not protect against moisture. So far, apparently only Sony has mastered these defense skills. The tablet is available in two colors: black and silver (almost white). In both variants, the aesthetically pleasing design, display size and solid build are impressive.

The device is convenient to use, which eliminates phantom clicks. On the right are the power, lock and volume keys, a slot for nano SIM and a memory card. Not very good placement of the lock and volume keys. Some reviews claim that this combination takes some getting used to. On the left is a keyboard magnet. At the bottom are the Type C port and 3.5mm headphone jack. At the top is a hole for a microphone and a biometric system for scanning the iris of the eyes and face. Also, a pair of powerful speakers were symmetrically placed on both sides.

Specifications

Screen

The Super AMOLED display isn't a surprise. It conveys a colorful and contrasting picture and has proven itself well, creating a clear view from any angle.

Unlike the previous model, the fingerprint scanner and touch-sensitive navigation keys have disappeared from the screen, which have replaced the retinal and face recognition sensors located on the case. As a result, the bezels have noticeably decreased on all sides and the diagonal of the multi-touch touch screen has increased to 10.5 inches.

2560 * 1600 screen expansion with 288 ppi and 219% sRGB. Such characteristics convey clear picture detail, perfect for high-quality video viewing and active games.

The glass protects the screen, which resists scratches and abrasions, and a special oleophobic coating prevents greasy streaks and prints, and is easy to clean. Plus, this protection does not create glare in the sun and the image remains clear even when looking against the light.

One of the differences between the AMOLED matrix is ​​the dependence of energy efficiency on the brightness of the display. The screen has many settings, from classic to full original design for yourself. The maximum brightness setting of 600 nits is only available in auto mode. There is a blocking of accidental touches and unblocking of double tap.

The tablet is turned on by means of an iris scanner and face recognition. This bio-identification creates information security. Although this system has not yet reached perfection, there are occasional minor glitches.

Additional sensors and functional applications:

• proximity sensor;
• light sensor;
• accelerometer;
• compass;
• gyroscope;
• Hall Sensor.

operating system

Samsung Galaxy Tab S4 is equipped with Android 8.1 platform, supplemented by Samsung Experiencem 9.5 proprietary shell, reminiscent of the beginning of S9, but there are significant differences.

DeX mode

The main feature of this business device is the DeX mode without additional docking stations and a monitor. With a keyboard and mouse, the tablet turns into an almost full-fledged computer with a desktop and multi-window mode. The DeX interface allows you to switch between applications and supports multitasking mode.

The Galaxy Tab S4 differs from the Galaxy S9 in its ability to open any application in full screen mode, not just games.

True, the screen in DeX mode does not rotate to vertical orientation.

Several useful applications

Numerous useful applications facilitate a varied workflow.

Microsoft Office has significantly improved, although, of course, it does not yet reach full-fledged work, but this option is most suitable for managers, top managers and those who do not need to process a lot of data.

Like the Galaxy Note phone, the Galaxy Tab S4 is powered by Samsung's KNOX mobile platform, which creates a multi-layered, single-handed, secure operating space for corporate and personal data.

There are also smart software features for creative people.

The SmartThings app allows you to connect and control compatible appliances remotely to create a smart home.

The presence of a child mode allows parents to protect their child from negative information, also providing the ability to customize the time intervals for training sessions or watching cartoons.

The Daily Board allows you to customize the display of your favorite photos on the screen, even in sleep mode.

Stylus

Samsung continues to develop its stylus-enabled devices. Here it is improved and worthy of all praise both in terms of performance and ergonomics. Ease of use and a tip reduced to 0.7 mm promote productive work and creative relaxation.

The S Pen senses pressure up to 4096 levels and tilt angle.Pictures are drawn like watercolors, you even need to take it away from the screen to restore the color tone, otherwise it will fade.

With the help of the stylus, you can take not only a screenshot of the full screen, but also individual fragments highlighted with it.

The screen sensors recognize both hand and stylus pressure, but you can set "S-pen only".

Like the Galaxy Note, you can take notes when the screen is off and save them.

The company specifically for using the S-Pen installed the application and social network Pen.UP on its device, where you can upload pictures and create small animations.

One problem is that Android doesn't have enough drawing software yet.

Keyboard

Separately, it should be said about the keyboard. It is not included and must be purchased separately, but its presence turns the tablet into a full-fledged laptop. 64-key keyboard is integrated into the case. The keys on it are located at a distance from each other, so it is comfortable to use. The only thing that complicates the workflow is the dedicated button on the right for switching languages ​​(Lang).

DeX mode, stylus and keyboard make for a powerful tool to work with.

Performance

In this model, Samsung did not install the new Qualcomm Snapdragon 845 processor, using last year's 8-core 64-bit Qualcomm Snapdragon 835 with a Kryo 280 chip clocked at 2.35 GHz. But this nimble and productive processor is not at all outdated, the tablet just flies on it, and besides, it has many optimized applications. There were questions about its performance, but according to the manufacturer, thanks to the Cat 16 LTE modem, the speed is tripled.

The processor is equipped with a graphics accelerator Adreno 540, with a frequency of 670 MHz, the performance of which has increased by 30% in comparison with the previous Adreno 530.

4 GB RAM, 64 GB permanent memory. The memory is fast, clocked at 1.866 GHz.

Such functionality contributes to the fast operation of the system, applications and games, even active ones such as PUBG or Battlefield.

Autonomy

The autonomy of the Samsung Galaxy Tab S4 tablet is supported by a 7300 mAh lithium polymer battery. Fast charging with Quick Charge 2.0 technology fully charges the battery in 3 hours and holds for a long time.

The operating time on a full charge at moderate brightness even with active use reaches 16 hours, but since the screen is volatile depending on the brightness settings, at its maximum, the tablet's working time is halved.

Cameras

Although the camera is not the main thing in this device, how it takes pictures is important.

Main camera

Rear camera - single 13 MP, aperture f / 1.9. The resolution of a frame with an aspect ratio of 4: 3 is 4160 * 3120 pixels with a standard size of 1.12 microns. Shooting speed 30 frames / sec.

The characteristics of the camera are not impressive, but they allow you to take high-quality pictures without blackout and flare.

Thanks to Sony's Exmor RS IMX320 sensor, focusing allows you to capture high-quality, even fast-moving objects. Autofocus and LED flash improve image brightness and sharpness, even at dusk.

The wide-angle lens increases the field of view by 76 °.

Video resolution at 30 fps - 4K UHD (3840 * 2160 pixels).

Additional features that improve functionality:

• continuous shooting;
• digital zoom;
• geotagging;
• HDR shooting;
• face recognition;
• ISO settings;
• scene selection mode;
• wide-angle lens - 76 °;
• touch focus.

Front-camera

Front camera - 8-megapixel with aperture f / 1.9, resolution 3264 * 2448 pixels. Photos are sharp, with natural brightness and no blur. There is an opportunity to shoot not only ordinary self-portraits, but also wide-angle ones.

High quality Full HD video recording at 30fps. It is possible to speed up the video up to 32 times ("Hyperlapse" mode).

The video is saved in MP4 containers (video in AVC format, audio in AAC).

Shooting has various modes, including professional.

The camera's shooting quality is typical and probably won't be able to compete with devices at the same price, but it is enough for video calls and selfies.

Bixby camera

We should also pay special attention to the Bixby camera. It determines which object has fallen into the camera lens and offers shops for its purchase, it also determines where the attraction is and translates information boards from foreign languages. The camera searches for goods in Yandex.Market.

Wireless interface

Internet access via mobile networks is carried out by the built-in X16 LTE Cat.16 modem. The tablet supports GSM, HSPA +, UMTS, LTE (speeds up to 1 Gbps). For real communication, the "Phone" application is provided. Navigation and positioning takes place using GPS with support for A-GPS, GLONASS and BeiDou, as well as Galileo. The presence of Bluetooth 5.0 and 2-band Wi-Fi 802.11 a / b / g / n / ac (2.4 and 5 GHz) plus WiFi Hotspot allow wireless data exchange between devices. There is no radio, and the lack of wireless charging is also unfortunate.

Sound

It should be noted the sound quality, which are responsible for 4 speakers, pumped by AKG technology. When Dolby Atmos is activated, the sound becomes surround sound with high quality stereo sound. The speakers come in loud enough to handle movie sound effects.

Where is it profitable to buy?

If when buying a tablet the selection criteria depend on how much the device costs, then the Samsung Galaxy Tab S4 is definitely not for you. It does not fall into the category: low-cost and budget tablets. Its average price is 50,000 rubles. You can buy it on the official website, other Internet resources and electronics stores.

Outcome

• reliable assembly;
• good color rendering;
• stereo sound;
• smart processor;
• long battery life;
• DeX mode;
• convenient stylus included in the package.

• high price;
• not very convenient arrangement of buttons;
• not good enough software for the S-Pen.

In general, the tablet is reliable and endowed with good functionality, although many characteristics correspond to a regular smartphone. The main feature is the DeX mode. Therefore, to the question: which tablet model and which company is better to choose? - everyone answers independently.
