What is an accelerometer in the phone
The term originally comes from the Latin word "Accelero", which literally means "acceleration." The device, called an accelerometer is used for measuring the apparent acceleration or the difference between the gravitational acceleration and true physical body or object.
Another name for the unit - G-sensor. Realization of the functions in the smartphone involves determining the angle of inclination relative to the ground surface of the apparatus by comparing the three-coordinate: X, Y and Z, or width, length and height, respectively.
The presence sensor will automatically change the orientation of the image on the screen
Special software is responsible for changing the orientation of the image on the screen depending on the received coordinate sensor.
But "smart" device, which has a compact size (less than 10-penny coin), is able to respond not only to the change in body position in a coordinate system. Additionally it receives external impact, such as shaking, push or turn. Depending on the configuration of software processes and requirements of the installed application, each action there is a reaction.
Driving device accelerometer classic
Every smartphone is one more sensor able to capture the change in the angle of inclination, which is called a gyroscope. Its task is identical and consists in determining the position of the device relative to the Earth's surface. Modern devices, are used to improve the data obtained directly from the two sensors, therefore, it can be said that they are complementary.
The principle of the device and of the sensor
In the classic version the sensor is small in size and has a simple structure composed of three components: a spring, the movable mass and damper.
The spring is attached to the fixed frame. At its free end is attached or bob weight movement is limited by a damper necessary to settle the vibrations generated during the rocking.
When the acceleration is observed mass movement, leading to deformation of the spring that is fixed measuring unit, converts these vibrations in specific quantities.
For qualitative response requires three sensitivity axes of the number of coordinates
Upon completion of manipulation due to the inertial mass of the spring takes its original position. Sensor is required for fixing the bias level changes with respect to dormancy.
Also, when it comes to the accelerometer, introduced such a concept as the axis of sensitivity of the device. A total of three, the number of components of the coordinate system. If there is a single axis sensor built able to transmit only position change within the sensitivity of the coordinates.

To achieve normal operation requires three sensitivity axes, then there is a complete calculation of the change in position of the device the three-dimensional coordinate system.
Modern mobile devices have small dimensions, as each manufacturer tries to make its flagship ultra-thin. Therefore, within the housing away classic accelerometer is not possible. He is replaced by a small chip inside which there is an inert mass, but there is a spring in the standard sense of the word, although sensitive sensors can accurately determine the change in the angle of inclination device.
The accelerometer can make phone building level, which will reduce the amount of the repair tool
Sensors for accelerometers manufactured automatically robotic machines. For instance working requires conducting a chemical reaction in which the interaction of silicone and other elements. Since the quality and accuracy will depend on the correctness of the calculations and proportions, the conditions of such a minimum size to achieve this by means of physical action impossible.
accelerometer functions and their application
The presence of the sensor in the smartphone is sufficiently useful feature because it provides a means to increase the comfort of using the device.

The man who could feel all the charm of the phone with an accelerometer, can no longer use legacy models that do not have a G-sensor, due to the lack of important functions that are already familiar in the modern world.
When counting steps smartphone also refers to data received from the accelerometer
Pedometer
The first application of the accelerometer will use it to determine the number of steps. This feature is useful to sports enthusiasts or people who are engaged in fitness. Also, a large number of modern phones have applications that allow you to monitor their own health, which necessarily there is a pedometer. The accuracy is not perfectly accurate, but it allows you to adjust your own training regimen to improve their performance.
Managing change in the angle of inclination of the smartphone in racing simulators increases the immersive gameplay and improves the accuracy of entering into a turn
Games Management
Another important function is the ability to control the game process by changing the inclination angle. Especially handy is in racing games where the smartphone accelerometer will replace vehicles, connected to a laptop or desktop PC to simplify the process and a greater sense of immersion in the game. control effectiveness will depend on the amplitude of the movements made.
Auto-rotate screen suitable for watching video or working with documents
Auto-rotate screen
Viewing a photo or video becomes more comfortable when you change the screen orientation to horizontal. This simplifies the perception of information and allows less eyestrain. It is responsible for a similar process in accelerometer. Also, by changing the position of the picture on the screen is easier to work with documents or spreadsheets.
One of the built-in accelerometer applications is the determination of the angle of inclination
Improving navigation
By built-in accelerometer improves work geopositioning device in space. This can be useful when working, even the most simple compass that will respond to changes in position of the device relative to the coordinate system.
Phone settings assume control of gestures, which is also activated by the accelerometer
Physical control of smartphone
Some modern flagships have the ability to control the operation of individual embedded applications through gestures or changing position of the device. The accelerometer is used to shift track music player, turn off the alarm, mute the incoming call screen when you turn the machine down.

In most cases, implementation of physical control smartphone must be activated in the settings, which must first carefully read the operating instructions or tips domestic helper.
Enable or disable the auto-rotate option in the settings made
Enable or disable
It is not always a function of the screen auto rotation is enabled by default, so you want to change smartphone settings to activate accelerometer. This can be done in two ways:
- By going to the settings menu, where you need to select the "Display" and just include auto rotation of the screen when changing the position of the device.
- By activating the desired item through the curtain notifications, which are icons for quick access to certain functions. Auto-rotate screen shows a little declination smartphone and stylized lines denoting movement.
The second way to activate the accelerometer is to choose the appropriate icon in the notification bar
At some points automatically change the image will stop. To disable this feature, you can use the above methods.
To calibrate the phone's sensors should be placed on a flat surface
sensor calibration
If there is a problem of the correct operation of the sensor, it is necessary to make its setup and calibration. This is a fairly simple process that is automated and requires the user to perform a minimum of action:
- Download the free app from PlayMarket.
- Installing smart phone on a flat surface.
- The inclusion of utilities and the transition to the "Calibration".
Next, the entire process occurs automatically with the user notification of its completion by the matching label.
Special application performs a calibration automatically without user intervention
The accelerometer does not work: what to do
There are situations when the sensor stops working properly, or refuses to function even after calibration. The problem may be caused by a software malfunction or failure of the chip itself. Depending on the causes of a different approach is needed to resolve the problem.
Regular updating of the software allows you to solve many of the problems with the software
software Fault
In this case, the user should remember the last installed applications, which could cause a conflict of hardware or software code. The first step is recommended to remove all new applications and test accelerometer.
If these steps do not lead to the desired result, then the second solution to the problem will be reset to its factory settings.

Before performing this operation, you need to copy all the necessary and important information from the device memory to a computer or inside the cloud storage.
Before resetting, be sure to back up in order not to lose information
To reset the phone to factory condition proceed as follows:
- go to the settings menu of the smartphone;
- select "Backup & reset";
- Activate the "Reset to factory settings";
- confirm the action.
After a while, the user receives a fully restored phone in the same condition in which it was after the acquisition.
Hard-Reset, or recovery through the engineering menu can also lead to the solution of the problem of software failure
Another way to "cure" software malfunction is a firmware update. Thus it is desirable to connect the phone to a WiFi network, since the new firmware can 'weigh' gigabytes. To perform a software update, you must go to the menu item "About phone", then select the line "Update". Subsequent verification of the availability of new versions and, if available, the user will only have to download them to your device and complete the upgrade process.
hardware failure
The second reason that may stop working accelerometer, is a hardware failure. The only way to restore the normal functioning of a treatment in specialized workshop, where the master will decide after the diagnostic measures, what kind of Repair is required. Replacement parts are mostly carried out on a new one, after which the work machine is restored.
Troubleshooting a hardware failure, operation of the accelerometer is only possible in the service center under a qualified technician
The accelerometer is an important detail that is necessary for the convenient use of modern smart devices. Also, such devices are used in the space industry, the industry for the control of vibration. Meet the accelerometer can be a hard disk, where it is used to protect against falls or shocks. More time to learn what it is, it is possible from the submitted videos.
