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.
Niche of the gadget
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.
Equipment
The equipment for this device is:
- 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 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.
Computational basis of smartphone
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.
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, 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.
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 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.
Memory
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.
Autonomy
Capacity of the complete battery of this deviceequal to 1600 mAh. On the one hand, it is one of the best energy-efficient processors, and on the other - the screen, though small, but with increased requirements for the capacity of the battery. As a result, one full charge of the battery will last for 2 days in the mode of medium load. If you save battery resources to the maximum, then you can add another 24 hours to this value 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. Explay A400 battery is not difficult to get. Therefore, in order to eliminate the possibility that this gadget will fail you at the most inopportune moment, it is recommended to additionally purchase a second such accessory.
Transfer of information
A decent set of interfaces in Explay A400. The characteristics in this regard are as follows:
- Full support for 3G networks and, of course, GSM.
- Built-in transmitter "Wi-Fi" standards b, g and n.
- Also for data exchange with similar mobile gadgets there is “Bluetooth”.
- To determine the location of the device, you can use the GPS-sensor.
- To synchronize with a PC and to charge the battery will have to use a wired micro-USB.
- To output sound to the wired acoustics, it is best to use an audio port.
Software
Операционная система в данном устройстве – "Android". Her version is 4.2. But unlike most similar gadgets, in which Google services are installed by default, applications from Yandex are installed here. Instead of “Chrome”, there is “Yandex Browser” here, instead of “Google Map” you can find “Yandex.Maps” here. Even instead of the usual “Play Store”, you will have to use Yandex.Market to install new applications. If necessary, you can add a set of software applications from the "Google", but it will take up additional space for other programs, the place simply will not remain. Therefore, it is necessary to use what is available.
Теперь разберемся с тем, например, как настроить The sound on Explay A400 is the fastest. To do this, click in the lower control panel left button. In the menu that appears on the touch screen, select "Settings". In the window that opens, we find the section "Device", and in it the item "Sound". From above, we select the type of sound profile, at the bottom we open it and configure it: set the melody for switching on, calling, vibration, etc. In the same menu, you can configure other program parameters of the device.
Smartphone cost
At the very beginning of sales, this gadget was rated at103 dollars. In the future, its value gradually decreased and reached $ 64. It was for so much that it could be bought in August 2015. This is quite a normal price, as for an entry-level smartphone. But now this gadget will not be able to buy, since all its inventory has been sold out.
And what about the owners?
A great entry-level solution for every day is the Explay A400 smartphone. Reviews indicate only its disadvantages:
- Small amount of RAM.
- Weak autonomy.
In the first case, the issue is solved by the installationspecial software, for example, "wedge-master". With it, you will have to periodically delete all unnecessary information from RAM. In the second case, with the help of specialized software, it is possible to stop all unnecessary processes and due to this, significantly save battery power. But there are much more advantages in this device:
- The presence of two cameras at once.
- Ability to install an external drive.
- Compact size.
- Democratic cost.
Summary
Of course, a 100% hit for the budget segment is notbecame the Explay A400. But, on the other hand, it is one of the first devices of this class of this manufacturer. And he managed to conquer a certain part of the market. Now he was replaced by more productive solutions for the same money that reinforce the achieved result. But the A400 can be considered a pioneer on this path, who managed to establish itself in a fairly short time.
