The summary table provides a visual comparison of the parameters of the models included in the review 7 inch tablets . You can see the full list of tablets in the corresponding catalog of tablets. And this article talks about five useful accessories for tablets.

Phone module with support for two SIM-cards, Android 7.0 OS, affordable price.
Short battery life, mediocre cameras.

In the battle on the field of ultra-low-cost tablets, Prestigio Grace 3157 3G defeats its closest rivals and takes the lead, drawing attention to its person with a balanced ratio of price and features.

In appearance, the model is a slightly bloated and diagonally stretched entry-level smartphone. At its core, the tablet is also not far removed from the family of "mobile phones" - the telephone module in its equipment allows you to make voice calls and access the Internet via 3G networks. To implement these tasks, the tablet is equipped with two compartments for SIM-cards.

The "iron" trio of a 4-core MediaTek MTMT8321В chip, Mali-400MP2 graphics and 1 GB of RAM provides the necessary minimum performance for comfortable use of the tablet on an everyday basis(watching videos, surfing the Internet and similar simple tasks). Serious games on the device are unlikely to start, and if they do, they will slow down or crash. In the AnTuTu performance test, the tablet earned 22 thousand points, which corresponds to the level of an entry-level device.

As for its value, the quality of the picture display on the Prestigio Grace 3157 3G screen is pleasantly surprising. Nevertheless, the display is based on an IPS-matrix with a resolution of 1280x800 pixels. The impression of the model is slightly spoiled by anachronistic cameras (2 MP at the back and 0.3 MP for selfies), along with a small battery capacity (2800 mAh) even by the standards of smartphones. It has enough energy for about 2.5 hours of screen activity, so it is preferable to use the tablet at home, in close proximity to the life-giving outlet.

Phone module with support for two SIM-cards, 2.5D glass over the front panel, Android 7.0 OS, affordable price.
Short battery life, mediocre cameras.

The products of the young Hong Kong brand Nomi, whose history began in 2013, captivate consumers with a “delicious” cost and good functionality. This is confirmed by the 7-inch tablet Nomi C070011 Corsa 2.

With a cursory glance at the device, you can’t say that we have a state employee in front of us - rounded 2.5D glass on top of the front panel and metal in the design of the tablet case increase its attractiveness in the eyes of potential buyers. Above and below the metal is diluted with plastic inserts. Behind the one located at the top of the case, there are slots for two SIM cards and a microSD standard drive, which comes to the rescue in increasing the amount of free space (built-in memory on board the device is 16 GB).

The model has acquired support for two SIM cards for a reason - they serve not only to access the Internet via 3G and LTE networks, but also to be able to use the tablet as a mobile phone(for calls, messaging, etc.). Communications in the arsenal of Nomi C070011 Corsa 2 are also represented by Wi-Fi, Bluetooth and GPS modules.

Inside the tablet, typical entry-level hardware is installed for a state-owned squad - a bundle of a 4-core chip from MediaTek and 1 GB of RAM. Nevertheless, under the control of Android 7.0, the gadget works smartly, the main thing is not to load it too much with "heavy" applications. Firstly, they significantly reduce performance, and secondly, they quickly “eat up” the charge of the built-in battery with a capacity of only 2500 mAh.

It is worth mentioning the photographic abilities of the tablet only for those reasons that its equipment includes two cameras: the main one with 2 MP and the front camera with 0.3 MP. Naturally, there can be no question of obtaining a high-quality result with their help - cameras are only suitable for photographing what is happening and organizing video communication. However, taking pictures on a tablet has never been considered a rule of good taste, so you can safely turn a blind eye to this minus of the device.

Decent display, metal case, decent build quality.
Poor performance, low screen resolution, mediocre cameras.

Huawei MediaPad T3 7.0 is a suitable model in the segment of affordable tablets, assembled in an anodized aluminium case. The device will fit undemanding users, but let's not get ahead of ourselves and dwell on the features of the tablet in more detail.

The main component of the model - a 7-inch screen based on an IPS matrix - boasts a high-quality image display with a slight oversaturation of colors(in the best traditions of AMOLED matrices). At the same time, due to the low resolution (1024x600 pixels), graininess is visible on the display, which interferes with reading small fonts.

The tablet is running a chip not the first freshness MediaTek MT8127 and 1 GB of "RAM". In benchmarks, this configuration gives a typical result for a strong state employee (about 26 thousand "parrots" in the AnTuTu performance test). In fact, the power of the hardware is enough to turn classic arcade games or puzzles and perform ordinary tablet tasks - flipping pages in the browser, watching videos and reading.

Cameras are not the strongest side of Huawei MediaPad T3 7.0 - photomodules with a resolution of 2 MP and fixed focus are installed both in the back and in front. Photos and videos are obtained on the "C grade". Against this background, the battery life of the gadget looks advantageous - about 6 hours of screen activity with continuous video playback. You will need to chain the tablet to a power outlet after a day of work under load, which is not so bad for a 3100 mAh battery.

Phone module with support for two SIM-cards, Android 7.0 OS, long autonomy, decent build quality.
Low threshold for maximum screen brightness.

The youngest model from the LenovoTab 4 series of tablets, shown to the public as part of the MWC-2017 exhibition, can be described in one sentence - this is a simple device at an affordable price for everyday use by children and adults.

The case of the device, although assembled from plastic, is done at a decent level - no squeaks or backlashes are observed during the operation of the tablet. A better grip of the gadget in the hand is facilitated by the textured surface of the back. All controls on the "body" of the model are adjusted to the portrait orientation of the screen. Landscape is also supported, but in this case, the likelihood of accidentally blocking the only built-in speaker combined with the conversational one increases with your fingers.

Lenovo Tab 4 7 7504X 3G can be used as a classic dialer and supports 3G/LTE data networks. If there is an available Wi-Fi network, the tablet accesses the Internet through it. A 3500 mAh battery charge when consuming content with an active Wi-Fi connection is enough for 10 hours of device operation without recharging.

The tablet's HD screen is strong both in terms of accurate color reproduction and wide viewing angles. But with a margin of maximum brightness, it did not work out in the best way, which is why when direct sunlight hits the display, the picture fades. The hardware part of the model is based on the MediaTek MT8735B chip (its four cores are overclocked to 1.3 GHz) and the minimum RAM threshold (1 GB) for comfortable operation. The tablet has more built-in memory - 16 GB (in addition, support for microSD memory cards is implemented). The capabilities of the platform are quite enough for browsing the World Wide Web, watching movies and online videos, as well as running casual games and non-resource-intensive applications.

Good for a tablet camera, does not slip out of hands, long autonomy, excellent build quality.
Low performance, low threshold for maximum screen brightness, insufficient internal memory.

The Tab A line of tablets from Samsung includes low-cost-class devices. The youngest representative of the series is a 7-inch tablet with support for 3G/LTE networks - Samsung Galaxy Tab A 7.0.

Compared to cheaper competitors from the Middle Kingdom, it is unlikely that the brainchild of the South Korean brand will be able to present any claims regarding the quality of performance. The manufacturer, although he created his product from plastic, nevertheless, the tablet received a textured back surface with anti-slip properties, which ensures a strong grip of the gadget in the hand. The high build quality is also evidenced by the fact that squeaks and backlashes are completely absent even in the case of attempts to forcefully bend the case.

The display of the model is built on the basis of IPS technology, and its resolution is 1280x800 pixels. The pixel density at a diagonal of 7 "reaches 216 ppi - the images look quite clear, but at a close distance, single pixels can be quite distinguishable with the naked eye. The screen has wide viewing angles, at the same time, the maximum threshold of its brightness does not contribute to a comfortable reading of information in bright sunlight light.

Not the highest performance makes the tablet an unsuitable option for gamers. During the AnTuTu synthetic test, a combination of a 4-core processor and 1.5 GB of RAM scores only a little over 22 thousand points - with such indicators, the model is more suitable for multimedia purposes (watching videos, browsing the Internet, communicating in social networks). True, for this you will need to get a microSD memory card, since the volume of the internal data storage is only 8 GB, of which only a little more than 4 GB is allocated to the user.

The main 5-megapixel camera in fairly good lighting produces quite good results. In the arsenal of the module there is an auto focus system, but there is no built-in flash. The front camera is more suitable for video communication. Finally, it is necessary to note the long-term operation of the tablet on a single charge of a 4000 mAh battery - according to the manufacturer, the gadget is capable of playing video for 11 hours in a row, and in practice this figure is confirmed.
