How can I enable or disable motion sensor function?
Motion Sensor is a function that contains an electronic sensor that recognizes whether the screen is in a vertical or horizontal position, and according to this, the function displays the screen in accordance with the position of the device screen.
If you do not need to use a motion sensor, or if you do not want to use it, you can turn off the motion sensor function. You can also include it at any time when you need it.
To enable or disable the Motion Sensor function (motion sensor):
1. Touch the Main menu icon in the lower right corner of the page.
2. Touch the setup icon.
3. On the Settings screen, tap the system at the bottom of the page.
4. Touch the motion sensor icon.
5. In the upper left corner of the screen, tap the Screen tab.
6. Select the option automatically to enable the motion sensor function or select manual when you do not use the motion sensor function.
Modern smartphones have a screen, which is only half a century shown only in science fiction. The touch screen perceives touching it and is able to work simultaneously both the output device and the input device. The combination of simultaneous information and the screen response to our real-time movements looks like magic, although, of course, in our time it has become a familiar thing.
Despite the fact that the essence of the sensory screens is the same, they differ in its device. There are several technologies:
- resistive;
- capacitive;
- optical;
- infrared;
- many other, more rare.
The emergence of the problem
Two types of sensory screens are most popular - resistive and capacitive. Resistive react to the distortion of the upper, flexible layer of the screen, which presses on the bottom layer, changing the current of the electric current in it. Based on these changes, the location is calculated. Capacitive screens do not have a flexible top layer. Instead, the current comes from the corners of the solid screen, and the distortion factor is the finger, changing the direction of the current.
In both cases, the screen reacts to pressing, which is obvious. Everything works fine when a person uses the screen for destination, fingers or stylus entering information or working with interface elements. But what to do if pressing the screen is random, for example, when the phone is in your pocket? To eliminate random clicks, the screen lock is used when the operating system of the phone receives an order or ignore the signals from the screen, or completely disable electricityshred to the screen.
What do we need to know?
However, there are regular situations that there is no possibility to block the screen, but it is not needed to press it. For example, such an obvious situation, when we use the phone to directly destiny - make calls to other people.
The sensitivity of modern touch screens is very large, why do not we activate the phone's interface with your ear when we try to hear the interlocutor through the speaker? The ear does not differ from the finger, it has the same conductivity, and of course, it is quite firm to accompany the top layer of the resistive screen.
This is where the approximation sensors are appreciated.
Sensor approximation and its function
There is something that combines automatic doors shopping center, Lamps of the entrance, which are included in the appearance of a person, and screens of smartphones. All these devices use contactless approximation sensors. These sensors are able to detect and respond to the position of various objects in relation to themselves.
In its technology, sensors, like screens, are divided into several types, the main of which are:
- inductive;
- cucitive.
Inductive sensors react only to metal objects, so they are not used in smartphone screens. But the capacitive capabilities are able to determine almost any object, the dielectric permeability of which is different from the air. Here, together with the object, form a peculiar spatial capacitor with a certain capacity. Through the change in the tank and the distance is determined.
The range of sensitivity of such sensors is small and depends on the size of the device itself. But, fortunately, the touch screen of the smartphone is a big range and is not needed - he only needs to respond to the approach of the ear during a conversation on the phone.
Application in smartphone
So, the approximation sensor is embedded into the phone so that it reacted to the object approach during the conversation and disconnected the touch screen. It pursues two goals - avoiding random coupling ear, and saving battery during long conversations, because the maintenance of the screen in the included state consumes a lot of energy.
There is this sensor in the most logical location - next to the phone's speaker. In modern models there is often small front-camera. Next to this camera or somewhere next door to the dynamics can be noticed another hole, it would seem that does not have functions. People often take him for the camera microphone or something like that. This is the approximation sensor.
The hole for the sensor is sometimes masked by hiding it under a decorative front panel. In this case, it is easy to detect, making a checking call to the number of his friend. If you do not bring the phone to the ear during a conversation, the screen will not go out, because it does not detect the object nearby. But it is enough to gently pull your finger in the dynamics area, as the screen will immediately go out. At what point the screen goes out - there is a sensor.
There are also problems in the operation of this sensor. In this case, the phone screen is either not turned off during the conversation, or vice versa, turns off at random moments. Knowing the basics of the sensor, it is possible to check whether it is whether it is possible, but it will have to change it in the workshop. It is better to entrust this business to real professionals.

The approximation sensor or in English interpretation - Proximity Sensor - is responsible for a number of functions implemented in the HTC smartphone, and also affects the operation of some applications using this sensor.
How to determine what the sensor does not work or function incorrectly?
To do this, it is enough to observe when in response mode to incoming call You attach the phone to the ear - whether the screen is automatically or not. If not, the approximation sensor works incorrectly.
What to do in this case?
Causes of problems can wage in incorrect work Phone firmware (especially often it occurs when installing all sorts of unofficial (custom) firmware), but it is not always necessary to update the operating android system. It is often enough to calibrate only the Proximity Sensor itself. To do this, use the Sensor BoxFor Android application (to check the sensor), the backlight of the touch buttons does not work in the article, as well as special application Proximity Recalibrator (or its analogues) for its calibration.
How to check the operation of the approximation sensor
- Connect smartphone htc. to the Internet, go to Play Market. And download the Sensor Boxfor Android applications (how to install the application from Play Market).
- Run installed application and click on the button Proximity Sensor.
- We check the operation of the approximation sensor, removing and bringing the hand or any other opaque subject to the phone display. If the sensor works fine, then the bottom will change the distance to the palm. Usually this sensor has only two values: the maximum (several centimeters) and the minimum (zero).
How to calibrate the approximation sensor
If the sensor does not work, you need to download and install the application for its calibration, such as Proximity Recalibrator.
- Open the installed application.
- We follow the instructions on the screen (it can be in English, but duplicate pictures description, as a rule, intuitively understandable). After each step, click "Next" (following).
- After performing calibration, reboot your smartphone.
* If the reason is not related to the physical fault of the approximation sensor, then after the procedures described above, its work is usually completely restored.
In recent years, all modern smartphones be iphons or android devices are equipped with a large number of sensors and sensors. Each of everyone has its own functions in the phone - measurement of heart rate and pulse, barometer for measuring pressure, accelerometer to calculate the location in space, turns. Today we will talk about the approximation sensor in the device - what is the device for which the performance of the sensor is intended for. Also dadim necessary information How to disable or enable, calibrate the sensor.
Sensor location and functional features
The sensor sensor of the approximation is located on the top of the facial side of the device. Usually there are speakers, camera, sensors of approximation and lighting. IN last models These sensors are combined into one.
How to find out where is the sensor? Call a friend and bring your finger close to the sensor (an example of the location in the screenshot below). When the screen goes out - congratulations to this and there is a approximation sensor.
The main function of this sensor is a reaction or an object approximation to the phone screen. Such a technology is invented for automatic lock Display during conversations by phone, communication via Viber or WhatsApp. Next call, please note how the screen goes like if you bring the device to the ear and then lights up after the conversation is complete.
The sensor itself sends an infrared light signal to determine what distance is the object and the approach is blocking.
With this approach, we get two large pluses at once:
- The screen is blocked from random coupling, which prevents accidental conversation, inclusion loud communicationIt is also by chance that you can translate the call to standby and TP mode;
- The second point is the savings of the battery of the smartphone. Phone display is the main source of power consumption, when the screen is enabled, the flow increases and the battery will quickly sit down. When you call with a shut off screen, the battery lives longer;
How to enable, customize the approximation sensor in the smartphone?
There are no settings as such by the sensor, as we have understood above - its main function is to block the screen when making calls. IN different versions Android and firmware OS most often find the inclusion of the sensor in the call menu. Click on the tube icon, then on the menu icon, to go to the required options.
If you have Xiaomi phone, Redmi models or other firm with MIUI 10 or MIUI 9 shell - open the settings, click on the phone number (or "call settings" for the 10th version of MIUI), we find the item "Incoming Calls" and turn on the item "Proximity sensor".
Sensor approximation does not work
If the approximation sensor does not work - check that it was in an activated position in the settings of incoming calls. Failures can occur when installing informal firmware, patches, some system updates.
In such cases, the right advice will only use official firmware From the manufacturer and try to make a general reset of settings.
For physical damage Resetting, flashing and other programs will not help, such a breakdown will help reveal service center With the subsequent replacement of the sensor.
For this, let's try to calibrate the sensor using the "Fix it Calibrate Sensor" application.
Calibration of the approximation sensor
As we wrote above, with physical breakdown, all manipulations will be useless. However, the utility "Sensor of the approximation Reset, repairs" download, you can download it by reference Google Play.: "Fix It Calibrate Sensor". After installing and starting the application, the application will try to discharge software settings and problems.

Sensors that recognize the object approximation without physical contact are embedded in many products of modern electronics. The easiest example is a crane in the public toilet, which reacts to the approach of the hand. Next - dryer in the same toilet, etc. With this, everything is clear, and what is the sensor approximation in a mobile phone?
What is it and why he need
Almost the same as in the crane. This technology is used in various touchpads, whereby:- first, electricity is saved;
- secondly, there is no need to mechanically turn on-shutting down devices, thereby extended their service life.
Problems in use
Many users have that the approximation sensor in the phone works incorrectly. The display is not blocked when approaching the ear, or vice versa, the display does not turn on and the phone will not unlock after the end of the conversation.To eliminate this trouble, you need to calibrate this sensor. For this you can download applications from the official site. In new android versions The possibility of calibration is provided.
So, in Android 4 versions and above necessary:
- Open the "Settings" menu, select " Screen"And" ALS PS Calibration"In the bottom line.
- Next, you need to put the phone on a flat surface, bring a sheet of paper sheet or another item at a distance at a distance of 1-5 cm, to keep motionless and press the Calibrate button.
- If the sheet of paper is put on the sensor, that is, it is completely closed - and click " Calibrate."It will be disconnected. But only before rebooting the phone.
