What is the role of the "gyroscope"? What is it meant by? And how can you know if your phone has it?
The interior of your mobile phone is full of sensors much more than you can imagine, each one dedicated to a completely different purpose, and although not all of them are necessary, the absence of one of them could lead to the loss of some important functions, or that some applications will not perform their function as they should.
This is the case of the "gyroscope", a sensor that the vast majority of smartphones have been incorporating for years, but we have seen in some models it disappear without warning, but first what is a "gyroscope" ? And why has it become so important?

The gyroscope has become an increasingly important component in modern mobile phones, especially after the arrival of advanced games and applications that take advantage of this type of sensor. Although in other areas we can find mechanical gyroscopes, in the case of smartphones this sensor is electronic.
Until a few years ago, mobile phones were only able to determine their position in the operating system through the accelerometer, another sensor that could only measure the position of the phone horizontally or vertically. But with the introduction of the gyroscope in phones , and the combination of this sensor with the accelerometer, the measurement of movements was more precise thanks to the sum of new dimensions of movement such as rotation or turns of the phones , so that a whole range of possibilities was opened to be able to know the position of the mobile phone at all times and in a precise way.
On a technical level, Microelectro Mechanical Systems gyroscopes found in smartphones, which are only between 1 and 300 micrometers in size, work in a way that enables them to detect changes in the phone's location, and convert the movement into a low-current electrical signal that is amplified and identified by a microcontroller, and is responsible for sending the signal to the operating system so that it acts accordingly.
Now that we have seen what a gyroscope is, and its role in the sensor's ability to measure the phone's movements very accurately. Now the question you will ask yourself is: Does your phone have a gyroscope?

The vast majority of modern mid-range and high-end smartphones have this sensor, although older or limited-spec devices can do without it.
Unlike other sensors in the phone, the gyroscope is hidden from the user's view. Fortunately, checking whether it is present in your phone or not is as simple as installing an application that allows you to know the components of your mobile phone, an example of which is the CPU-Z application, which is available for free download on Google Play from the following link

Once you have installed the application and granted it the necessary permissions, you should access the "Sensors" section, and in the complete list of sensors look for those that have the word "Gyroscope" or similar. A series of numerical values should also appear, which will vary when you move the mobile from one side to another or rotate it.
There is no doubt that this small sensor is much more important than it might seem at first, and it is certainly a pity that some manufacturers have not decided to integrate it into all the devices that make up their catalog.
