Accelerometer(or G-sensor) - sensor of the device’s position in space. As the main function, the accelerometer is used to automatic change orientation of the image on the display (vertical or horizontal). Also, G-sensor is used as a pedometer, it can be controlled various functions device by turning or shaking.
Gyroscope- a sensor that measures rotation angles relative to a fixed coordinate system. Capable of measuring rotation angles in several planes simultaneously. A gyroscope together with an accelerometer allows you to accurately determine the position of the device in space. Devices that use only accelerometers have lower measurement accuracy, especially when fast movement. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor that sets the optimal brightness and contrast values for this level illumination The presence of a sensor allows you to increase the battery life of the device.
Proximity sensor- a sensor that detects when the device is close to your face during a call, turns off the backlight and locks the screen, preventing random clicks. The presence of a sensor allows you to increase the battery life of the device.
Geomagnetic sensor- a sensor for determining the direction of the world in which the device is directed. Tracks the orientation of the device in space relative to the magnetic poles of the Earth. The information received from the sensor is used in mapping programs for terrain orientation.
Atmospheric pressure sensor- sensor for precise measurement atmospheric pressure. It is part of the GPS system, allows you to determine altitude above sea level and speed up location determination.
Touch ID- fingerprint identification sensor.

Satellite navigation:
GPS(Global Positioning System) is a satellite navigation system that provides measurements of distance, time, speed and determines the location of objects anywhere on Earth. The system is developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine location by measuring distances to an object from points with known coordinates - satellites. The distance is calculated by the delay time of signal propagation from sending it by the satellite to receiving it by the antenna of the GPS receiver.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measurement principle is similar to the American GPS navigation system. GLONASS is designed for operational navigation and timing support for land, sea, air and space-based users. The main difference from the GPS system is that GLONASS satellites in their orbital motion do not have resonance (synchrony) with the rotation of the Earth, which provides them with greater stability.
Alcatel POP 2 5042D, which we will talk about today, is a continuation of the line called One Touch. This Chinese device is sold locally Russian Federation for only five thousand rubles.
Briefly about technical characteristics
Later we will talk about the parameters of the Alcatel POP 2 5042D in more detail, but now we will look at the fundamental points. You could say the cornerstones on which this device is based. So, for a price of 5 thousand rubles we are not getting the newest shell software(“Android” 4.4), not the largest volume random access memory(1 GB) and not the best quality screen. Time battery life The device will not please us either, the battery is designed for only 2,000 milliamps per hour. But the communication capabilities of the Alcatel POP 2 5042D are fine. Nevertheless, who will look at the set of communications if they do not allow you to use the device? for a long time? But first things first.
Display
It's safe to say that the screen is the part of the smartphone where you encounter the most noticeable paradox. On the one hand, the Alcatel POP 2 5042D is equipped with a TFT matrix, which today has the worst display quality. It is easily overtaken by IPS, but we don’t even have to talk about AMOLED and S-AMOLED.
Basic indicators
So, POP 2 5042D has a screen resolution of 480 by 854 pixels with a diagonal of 4.5 inches. Calculations indicate that the pixel density is 240 pixels per inch. If the manufacturer installed an IPS matrix in the screen rather than a TFT one, this would be noticeable progress and could greatly change the rating of the device. Nevertheless, the TFT matrix, or rather its installation, is a kind of payment here for the low cost of the device. Actually, there is another justification for using TFT: low battery capacity. Such a matrix will consume charge more efficiently than the same IPS.
Color rendition
It is pleasantly surprising that the screen does not give off excessively blue tints, as is the case with many budget solutions. In general, the color rendering of the POP 2 5042D is good; it is at a good level. There is an almost crystal clear white color here, for which I would like to thank the developers. And this is even at low brightness levels. Yes, of course, there were some errors. For example, in small text you may notice blurring of fine lines, and when you turn the device into a vertical plane, distortion will occur color range. But can opponents boast of anything else? Alcatel One Touch POP 2 5042D, related to the same price category? Hardly.
Additional modules and functions
More Alcatel smartphone equipped with a light sensor that allows you to adjust the screen backlight level according to automatic mode. Considering that not all models costing seven thousand rubles have this function (and even those costing ten thousand rubles, oddly enough), you can be happy about such a set. By the way, the Alcatel smartphone changes the brightness level without any jerks, doing everything softly, smoothly and gradually.
The developers have added enough to the device interesting solution. Like Lumiya, the device can be either woken up from sleep mode or brought back into sleep mode by double tapping the display. When you “wake up,” the main screen will immediately open, and the lockscreen will be skipped. The same can be done exactly the opposite.
Camera
Alcatel POP 2 5042D, the price of which is about five thousand Russian rubles, is equipped with two cameras. The main one has a resolution of five megapixels. The front one is more modest, only two megapixels. The main module is complemented by the function of automatic focusing on the subject, and there is an LED flash. However, you shouldn’t place a huge bet on it, since it copes with its tasks (due to low power) very, very mediocrely.
Inconsistencies
By the way, problems were identified with the front camera. The previously provided information about two megapixels was received from developers and company officials. However, repeated tests carried out using special software showed that there is only 0.3 MP. We won’t notice any special settings, there are only two of them: activating/turning off the night mode and creating four photos in a row. The compression algorithm is good and allows you to save space on your phone. It is possible that the company initially planned from 0.3 to 2 megapixels, but for some reason decided not to do this. For those who are not experienced in selfies, the result will still be acceptable.
What about the main camera?
The Alcatel POP 2 5042D, the firmware for which will optimize the operation of the operating system, has a fairly good main camera. Despite its five megapixels, in good lighting it produces really high-quality images. In parallel with how the light level drops, the quality will also deteriorate, but this seems quite logical. Automatic focusing not only works quickly, but also competently; you won’t be able to dig into the process or results.
Software part
The work of software and hardware that corrects results in the creation of good pictures. Even without setting advanced settings, you can take high-quality photos in almost any type of lighting. When shooting faces, the user can enjoy a slight shift in the spectrum towards warmer tones. This parameter has almost no effect on other scenarios, so it can be assessed positively. There is a macro mode. It will not provide perfect results. Nevertheless, lovers of shooting flowers and other objects can safely count on it.
Macro
What can you say about photos with text? In principle, it is unlikely that you will be able to boast about any extraordinary achievements. But the necessary level is still present. If you take a photo of an A4 page, the text on it will be easy to read even without special scaling. However, readability will decrease in proportion to the reduction in letter size. Alcatel POP 2 5042D, the characteristics of which are listed at the beginning of the review, does not allow good shooting at night. Even though it has flash. Its only sensible purpose is to use it as a flashlight.
Practical use
If you active user, then you will definitely have to purchase a case for the Alcatel POP 2 5042D, so as not to damage the case and not wash the coating. We have already talked about the operation of the display, so there is no point in repeating ourselves. You can look at the topic of communications, which will probably be more interesting for those who are planning to use a smartphone for its intended purpose. That is, actively communicate on social networks, browse the Internet and call up loved ones.
So, in the fourth generation cellular network the device works quite quickly. It immediately “clings” to the coating. Considering the price of the device, this is even a little surprising in a pleasant way, of course. The signal indicator shows impressive information. In general, the device switches from the third to the fourth generation and back very quickly. And it really makes me happy. It is clear that in this case there can be no complaints about the quality of data transmission. No problem here.
Wireless networks and speakers
Sensitivity Wi-Fi module on high level, there are no complaints against him. I was pleased with the fast and accurate operation of the GPS. There is an A-GPS add-on, which once again makes it easier to work with satellite maps terrain. Coupled with a good “hook” of the smartphone on the coating cellular networks, these parameters provide an excellent opportunity to use the device as a communicator. The radio part was done superbly, you can’t argue with that.
As for the sound, this part of the subject of our today's review is the very fly in the ointment. It becomes a kind of rehabilitation. The multimedia speaker is far from perfect. Hissing and crackling - these are its main shortcomings. There is nothing else to highlight, but this “sweet couple” is enough, as they say, for the eyes. Probably, Alcatel should have gone in this direction with an eye on the ingenious solutions of the Beeline company, where there is no multimedia speaker, and its role is played by a universal auditory speaker.
