A simple entry-level smartphone with fulla set of all the basic functions - Explay A400. This device boasts a very democratic price tag of 3,500 rubles, but its hardware resources are enough to solve most problems. It is the parameters of this gadget that will be considered in this small survey material.
Technical specifications, very smallcost, diagonal display of 4 inches - this is not a complete list of features that clearly and unambiguously indicate that we have an entry-level device, or, as it is sometimes called, a budget gadget. This is an excellent solution for most everyday tasks. The only thing that this device can not cope with exactly is the most demanding three-dimensional toys. In order to play in them, you need to purchase a more expensive device. But with everything else "A400" just fine.
The equipment for this device is:
Almost the entire front panel of this gadgetis occupied by a touch screen. Underneath is a typical control panel of 3 buttons. On top of that, there is a speaker, several sensors and an eye of the front camera. On the right edge of the device is a lock button, and on the left - the volume control buttons. On the lower edge of the device there is a hole of the spoken microphone. But on top of all the wired interfaces: micro-USB and audio port. On the back cover, in addition to the manufacturer's logo, there is also a loud speaker, a main camera and LED lighting for it.
Explay A400 is built on the basis of CPU MT6572company-developer "MediaTek." This is an entry-level chip, which consists of only 2 compute modules based on the "A7" architecture, and is manufactured in accordance with the requirements of the 28-nm process technology. The frequency at them is able to dynamically increase to 1.3 GHz when performing the most complex tasks. If the device has enough processing power for a single core, then the second one is turned off. Also, with minimum load, the frequency of each module is automatically reduced to 300 MHz. As a result, it can be noted that this semiconductor crystal can boast a high level of energy efficiency. But his productivity is at the minimum level, and he simply does not have any performance margin. But to solve most everyday tasks this is enough.
The display is exactly the weak point of the Explay A400.His technical characteristics are really modest. The screen diagonal is only 4 inches. On the one hand, it makes it possible to manage the device with only one hand without any problems, and on the other hand it is not always possible to disassemble large objects on such a display. The screen resolution is only 800x480. The density of pixels on it is 233ppi. The image on it, of course, is not grainy, but individual pixels can be disassembled if desired. The display matrix in this device is manufactured according to the outdated technology - TN. The viewing angles are minimal, and even with a slight deviation from 90 degrees, the image becomes very distorted. The second important disadvantage of this technology is the increased energy consumption. Therefore, the battery of this gadget is subjected to more stringent requirements to ensure the necessary level of autonomy.
Not a bad main camera at 5 megapixel in the Explay A400.Photos at a normal level of illumination with her help you get very much even nothing. Autofocus in the device is not, but a single LED backlight, of course, is. Among other features of this gadget is to note the presence of digital zoom. Also there is support for video recording. The front camera is based on a very modest sensor of 0.3 MP. This is enough for video calls. But for the now popular "Selfie" will clearly not be enough.
Phone Explay A400 is equipped with only 512 MBrandom access memory. At the same time, most of them are occupied by the operating system (about 300 MB). As a result, the user can count on 200 MB. To run 2-3 simple applications this will be enough. But if you try to run several heavy applications at the same time, then the smartphone will start to slow down. In some cases, you may need to reboot it. The capacity of the integrated drive in this gadget is 4 GB. At the same time, the operating system itself is about 2 GB. 800 MB is reserved for the installation of user applications, but for storing personal information the user can use the remaining 1.2 GB. This is clearly not enough to reveal the full potential of this gadget. Therefore, you need to install in this device external flash drive. The maximum size of it can be equal to impressive even by today's standards of 32 GB. The required slot for these purposes in this device is.
The battery capacity of this unit isis equal to 1600 mAh. On the one hand, it has one of the best energy-efficient processors, and on the other - a screen though small, but with increased requirements for capacity to the battery. As a result, one full charge of the battery will last for 2 days in the medium load mode. If you save battery resources to the maximum, you can add to this value for another 24 hours and get 3 days of battery life. Well, when you start the game on this smartphone, battery life will be reduced to 8-9 hours. That is, in this mode, you have to charge the smartphone every day, or even 2 times. The battery on the Explay A400 is easy to get. Therefore, in order to exclude the possibility that this gadget will let you down at the most inopportune moment, it is recommended to purchase an additional accessory in addition.
A decent set of interfaces in the Explay A400. Characteristics in this regard, he has such:
The operating system in this device -"Android". Its version is 4.2. Only here, unlike most similar gadgets, in which Google services are installed by default, there are applications from "Yandex" installed here. Instead of "Chrome" here is "Yandex.Browser", instead of "Google Map" here you can find "Yandex.Maps". Even instead of the usual "Play Store" for installing new applications, you will have to use "Yandex.Market". If necessary, you can supplement the software suite with applications from Google, but this will take an additional place and there will simply not be a place for other programs. Therefore, we will have to use what is available.
Now we'll figure it out, for example, how to set upThe sound on the Explay A400 is fastest. To do this, click on the bottom control panel left button. In the appeared menu on the touch screen select the item "Settings". In the opened window we find the section "Device", and in it the item "Sound". From the top choose the type of sound profile, at the bottom open it and configure: set the melody of inclusion, call, vibration, etc. In the same menu, you can configure other program parameters of the device.
At the very beginning of sales, this gadget was evaluated in103 dollars. In the future, its value gradually decreased and reached $ 64. It was for so much it could be bought in August 2015. This is quite normal cost, as for an entry-level smartphone. But now this gadget will not be able to buy, because all its stock is sold out.
An excellent entry-level solution for every day is the Explay A400 smartphone. The reviews only point out such minuses:
In the first case, the issue is solved by installingspecial software, for example, "Wedge-master." With it, you need to periodically remove all the unnecessary information from the RAM. In the second case, too, with the help of specialized software, you can stop all unnecessary processes and, due to this, you can save a lot of battery power. But the advantages in this device are much larger:
Of course, a 100% hit for the budget segment is notbecame Explay A400. But, on the other hand, it is one of the first devices of this class of this manufacturer. And he managed to win a certain part of the market. Now he is replaced by more productive solutions for the same money, which consolidate the achieved result. But the pioneer on this path can be considered exactly "A400", which for quite a short time managed to prove itself from the best side.
