Android gyro calibration: why doesn’t it work, how to enable, install and configure

Smartphones are equipped with a large number of sensors that make the interaction with the gadget more comfortable. In particular, mobile devices are equipped with a gyroscope. It is an integral part of most models and requires periodic maintenance. In the process of maintenance, the gyroscope is calibrated on the Android operating system.

What is a gyroscope and what does it do

To understand what calibration is required for, it is enough to say a few words about the sensor itself. A gyroscope is a device that determines the position of the body relative to the ground. On Android, it is used as a means to implement functions such as auto-rotate the screen.

Gsensor senses that you are holding the phone horizontally and therefore changes the orientation of the interface according to your position. Similarly, the interface returns to the vertical position. Also the gyroscope finds its application in games, whose control is based on changing the angle of inclination. A striking example is Real Racing 3 and other races.

How it works and how it works

The gyroscope appeared in 1817, when the world had no idea that someday in the hands of everyone will be a means of communication in the form of a smartphone. Since then, the way the sensor works has changed a lot. The Gsensor was a circle with a spinner placed in the middle. It always stays in place, unlike the frames surrounding it. It is by changing their position that the position of the body in space can be determined.

Because of their compactness, smartphones simply cannot get hold of such a massive structure. Therefore, the manufacturers of gadgets went the other way. Instead of frames and a wave, the phone’s Gsensor uses moving masses of matter, which, similar to the classic gyroscope design, change their orientation. The change in position is registered by a microprocessor, so the smartphone understands how you are holding it.

How to check if your phone has a gyroscope

Despite the fact that Gsensor is one of the main sensors of a smartphone, on some models it may be missing. In this case, there is no need to calibrate, and therefore it is important to determine the presence of the sensor. You can do this with the help of third-party software. For example, through the AnTuTu benchmark. It not only determines the performance of the smartphone, but also shows its characteristics. Under “My device” you will find the item “Gyroscope”. If the value here is “Not supported”, then there is no Gsensor.

In a similar way you can check the presence of the gyroscope through AIDA64. Unlike AnTuTu, this app is available for download via Play Market. Another example is Sensor Sense, a program that shows a list of all supported sensors.

Finally, it is possible to determine the presence of a sensor by indirect signs. If your smartphone has auto-rotate screen, in the camera settings there is an option to create a panorama, and in the game Real Racing 3 the car is controlled by tilting the device, the gyroscope is in place. At the same time, the sensor can fail or work incorrectly, and therefore it is best to check its presence through specialized software.

Enabling and disabling the function

By default, the gyroscope is always active, and you cannot disable the sensor. However, you have the ability to activate and deactivate functions that use the Gsensor. A striking example is the screen auto-rotate. To activate or deactivate it, you will need:

  • Open the phone settings.
  • Go to “Screen” and then to “When you rotate the device” (depending on your smartphone model, this item may be called differently).
  • Set the value to “Off”.

You can also adjust the function through the control center. It is called by swiping from the top of the screen down. You will see about a dozen icons in front of you, each of which is responsible for a particular option. As a rule, under the icon with the function that uses the gyroscope there is an inscription “Auto-rotate”. If the icon is highlighted – the option is working. If it is grayed out, the function is disabled.

In addition to enabling and disabling the screen autorotation you can calibrate the gyroscope. However, for this you will need to install specialized software. The best option is the Accelerometer Calibration app. Despite the fact that it is aimed at calibrating the accelerometer, the program is also used to adjust the G-sensor:

  • Using the Play Store, install Accelerometer Calibration on your phone.
  • Place your smartphone on a flat surface.
  • Start the program.
  • Make sure the red dot is in the center of the square.
  • Press the “Calibrate” button.

This simple operation allows you to increase the accuracy of the sensor, which is expressed not only in a more responsive control in games, but also in the correct functioning of the auto-rotate screen. So if you were previously uncomfortable with unintentional screen position changes, Accelerometer Calibration can help solve the problem.

Why it may not work

If your smartphone does not work gyroscope, then first you need to check its presence by one of the ways discussed earlier in the material. It is possible that your model is simply not equipped with a G-sensor, and therefore it is not worth counting on its work.

Another thing is when the control center has the “Auto Rotate” option, and the camera has a panorama shooting mode. This is indirect evidence of the presence of Gsensor. In this case the sensor failure can be caused by mechanical damage to the gadget. Unfortunately, you can solve such a problem only by replacing the sensor. But do not rush to take drastic measures. Try to calibrate the gyroscope. It is possible that after that the sensor will work.

If we are talking about the incorrect operation of the gyro, when the interface is rotated in the wrong direction, then the only solution is calibration. However, when the phone uses a cheap sensor, even such an operation is not able to improve the result.
