Many owners of Android – devices with a touchscreen display often face a problem when the screen is 'not listening' to them. That is, when you touch the touchscreen with your finger or stylus at one point, the phone perceives it as touching completely at another point. Or, the sensor completely fulfills orders with only 3-4 attempts. And most likely the reason for these problems is the incorrect operation of the screen, and in order to fix it, you need to calibrate the touchscreen of the Android device.

What it is?
Screen calibration is setting up the touchscreen to correctly execute commands when you touch it with your fingers or stylus. Of course, you can work with your device without such a setting, but then get ready to waste your nerves, time and other troubles.
This procedure is required in most cases after the phone has been dropped, especially in water. Replacing the screen, the water stain under it, even the smallest damage may require urgent adjustment. Checking if you need calibration is as easy as shelling pears. First, remove the protective film to make the sensor work as clear as possible, then just enter any number or letter. If you have chosen, say 'B', and 'A' appears on the screen, then be sure – you need to configure the touchscreen.
There are two main types of screens used in the production of Android devices: capacitive and resistive. Capacitive is now used in the absolute majority, since it is more reliable and of high quality. But with resistive, problems often arise, and it requires tuning more often. But the good is that now these are rarely used – only in outdated or budget models.

Contacting the service center
Now you know two ways to independently calibrate the screen on your Android – device. But there is also a third option for setting up your device – this is an official or private service center.

It happens that the cause of the breakdown is not in the knocked down settings, but in a serious breakdown or in the factory marriage of the display. In this case, it is really better to contact the service if the first two did not work.
