Smartphone Explay A400: specifications, description. Owner feedback

A simple entry-level smartphone with a full 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.

Niche of the gadget

Technical specifications, very small cost, a diagonal of a 4-inch display 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.

Equipment

The equipment for this device is as follows:

  • The "smart" phone itself.
  • Battery for 1600 mAh.
  • User guide.
  • Stereo headset.
  • Standard interface cable.
  • Warranty card.
  • Charger.

Appearance

Almost the entire front panel of this gadget is occupied by a touch screen. Underneath is a typical control panel of 3 buttons. On top of this, there is a speaker, several sensors and a pic- ture 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.

Computational basis of smartphone

Explay A400 is built on the basis of the CPU MT6572 of the developer company "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 washes dynamically to 1.3 GHz when performing the most complex tasks. If enough computing powers of one core are sufficient to ensure the device's performance, the second one is turned off at the same time. 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.

Display and graphics accelerator

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, this makes it possible to manage the device with only one hand without problems, and on the other hand, it is not always possible to disassemble large objects on this 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.

Cameras

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 little. Autofocus in the device there, 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.

Memory

Phone Explay A400 is equipped with only 512 MB of RAM. 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 have 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 to store 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 will have to install an external flash drive in this device. The maximum size of it can be equal to impressive even by today's standards of 32 GB. The necessary slot for these purposes in this device is.

Autonomy

The total battery capacity of this unit is 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, the battery life will be reduced to 8-9 hours. That is, in this mode, you have to charge your 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.

Transfer of information

A decent set of interfaces in the Explay A400. Characteristics in this regard, he has such:

  • Full support for 3G networks and, of course, GSM.
  • Built-in transmitter "Wai-Fay" standards b, g and n.
  • Also for the exchange of data with similar mobile gadgets is "Blutuz".
  • You can use the GPS sensor to locate the device.
  • To synchronize with the PC and to charge the battery you will have to use a wired micro-USB.
  • For audio output to wired acoustics, it's best to use an audio port.

Software

The operating system in this device is Android. Its version is 4.2. Only here, unlike most similar gadgets, in which Google services are installed by default, there are applications installed from "Yandex". Instead of "Chrome" here there is "Yandex.Browser", instead of "Google Map" here you can find "Yandex.Maps". Even instead of the usual "Play Store" for installing new applications will have to use "Yandex.Market." If necessary, you can add a set of software applications from Google, but it will take additional space and for other programs, the site will simply not remain. Therefore, we will have to use what is available.

Now we'll figure it out, for example, how to set up the sound on the Explay A400 most quickly. 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 software parameters of the device.

Cost of smartphone

At the very beginning of sales, this gadget was valued at $ 103. In the future, its value gradually decreased and reached 64 dollars. It was for so much it could be bought in August 2015. This is quite a 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.

And what about the owners?

An excellent entry-level solution for every day is the Explay A400 smartphone. The reviews only point out such minuses:

  • Small amount of RAM.
  • Weak autonomy.

In the first case, the issue is solved by installing a special software, for example, "Wedge-master." With it, you will need to periodically remove all 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 is much larger:

  • The presence of two cameras at once.
  • Ability to install an external drive.
  • Compact size.
  • Democratic cost.

Summary

Of course, the 100% hit for the budget segment was not the Explay A400. But, on the other hand, this 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 a short time has proved itself from the best side.
