How to Install an Android Gyroscope
Modern smartphones offer among their features really amazing functions, which a few years ago could only be used in the military field and by companies with the budget to implement these tools.
These features include GPS, CMOS sensors for cameras and gyroscope, among others, all of which are widely used, and almost indispensable, sensors today.
Today these tools are within everyone's reach thanks to the fact that electronics has reached a very high level of miniaturization, which leads to a reduction in your production costs and therefore in the final price to the consumer.
It is for this reason that today sensors such as the gyroscope and GPS can be incorporated into all types of mass consumption devices, such as digital cameras, cell phones and tablets.
However, not all cell phones have gyroscope, only those of medium-high range, and therefore in this article we have tried to find a way for everyone to install a gyroscope and be able to use it for their virtual reality applications using VR glasses, augmented reality to play Pokemon Go and view images and videos at 360°, among other applications.
What is the gyroscope?
Basically, a gyroscope is an electronic component, precisely a small chip that is installed in the motherboard of the phone, and through which we can obtain precise information about the orientation and spatial location of any device that has it installed.
In the case of smartphones, the gyro, or gyro, as it is also known, allows the device to know its orientation and precise location for use in applications that require this type of data, as is the case of the popular game Pokemon GO. The gyro can provide this orientation and location information by reading the position of 6 axes housed inside the chip.
As mentioned, low or mid-range cell phones do not include a gyro. But if we still have doubts, we can always install some app in our Android to know if we have gyroscope.
In this sense, one of the most popular is Sensor Box, which besides telling us if we have gyroscope in the phone and let us know some readings of it, will also inform us about the other sensors that we have installed in the smartphone.

Is it possible to install a gyroscope?
Being an electronic component, and also very sensitive, the gyroscope can not be physically installed in cell phones, at least by the common user, ie buy the component and solder or mount it on the board. However, this does not mean that there is no way to emulate the functions of a gyroscope.
Fortunately for users who do not have a high-end cell phone, some developers have managed to combine the readings of the accelerometer and magnetic sensor values, which can emulate the presence of the gyroscope.
Install gyroscope for Android
While this procedure to install a gyro in Android should work correctly on all phones with this OS, the truth is that each model and maca have their differences.
This does not allow the procedure for installing a gyro to be standardized, so we must look for the mere fact of doing so for our specific device. The same happens with the procedure to be root, for each model and brand is different.
Step 1: Root
It should be noted that before we start emulating a gyroscope on our cell phone, we need to have root permissions, because we must move files to the folder of the Android system, and without being root we can not.
Step 2: Create the Controller
After achieving these goals, we must create a file with the text that is transcribed below, which we can write in any text editor as Notepad and save as "android.hardware.sensor.gyroscope.xml" in the internal memory of the cell phone.
<?xml version="1.0? encoding="utf-8??>
<feature name=”android.hardware.sensor.gyroscope” />
Step 3: Install the driver
Once we do this step, the next thing to do is move it or copy it to the Android system folders, specifically to the "system/etc/permissions" location.
Next we will mount this folder with write permissions, which we can do by pressing the button "Mount R/W" or similar, depending on the file explorer we use for the procedure, which can be anyone if we are root.
When we have done this, we can move the file "android.hardware.sensor.gyroscope.xml" to this location.
Step 4: Give the necessary permissions
Finally, all that remains is to change the file permissions.
To do this, click on the file "android.hardware.sensor.gyroscope.xml" and open the permissions window, and change the original permissions of the file for the following:
Step 5: Final Check
Once we've completed all the steps perfectly, all that's left is to close all the apps we've used and restart the phone for the changes to take effect. When the smartphone restarts, to check that the procedure has been successful, we run Sensor Box.
If everything went well, we'll be able to see a painting like this.
From this point, we can use the gyroscope to play Pokemon Go or use Google SkyMap, among other applications.
It should be noted that it is possible that some of the applications that use gyroscope can not be installed from Google Play, because the system recognizes that we do not have such a sensor.
However, we will be able to download and install them from other sources such as Aptoide without problems.
Despite requiring root, the procedure to install a gyroscope in Android described in this article is quite simple, since the only thing we will need is a file, a file explorer, which for the case may be the one we usually use, and above all, a little patience.
Although there are other procedures to install gyroscopes in the cell phone, the truth is that they require changing the ROM, which indicates flashing the phone, undoubtedly a difficult and very complicated task that we must leave to the experts.
