How to Calibrate Your Touchscreen on Android
Over time, the touch screen of your Android device could start to fail. Before considering replacing your device, you should see if touch screen calibration can solve any problem. Here’s how to recalibrate your Android smartphone or tablet.
Does your touch screen need calibration?
As Android has advanced and developed over the years, so has the hardware with which it runs. Android hardware today is much better and more capable than previous generations.
Modern Android touch screens rarely require the user to calibrate or configure it in another way. Touch screen faults are more likely to be caused by hardware problems that cannot be fixed than any particular configuration problem.
That said, calibration should not be completely ruled out, as it may be useful in some circumstances.
For example, it can be a good way to adjust the sensitivity of the touch screen, especially if there is something else that affects it. Certain types of screen protectors, for example, can affect the performance of your touch screen. This is a problem that calibration can sometimes improve.
It is also good to test this on older devices where the technology was not as advanced and calibration can have a greater and more noticeable impact. There is no harm in performing a touch screen calibration, regardless of its age, but older devices are likely to benefit more from it.
Before you begin, you should see if the touch screen of your Android device is fully operational.
Earlier versions of Android included secret menus and developer options that allowed you to test and calibrate your touch screen. This was important on older Android devices, when modern touch screens were still in diapers.
If you have an older Android phone, you can try accessing this secret touch screen menu by dialing * # * # 2664 # * # * . This option will not work on Android devices from Android 5 Lollipop onwards.
For modern Android devices, there are applications available in the Google Play Store that will allow you to test the touch screen. These will show you the answers to your touch on the screen, helping you judge whether the screen is calibrated correctly or not. A good option to try is the Touch Screen Test.
It is easy to use. Install it and touch the screen wherever you want.
The application, like a brush, will register white dots where you press your fingers. If the responses are slow or not synchronized, that would indicate a problem with your screen that calibration could solve as a first resource.
Calibrating your touch screen
As we mentioned, previous versions of Android included in calibration tests. These tools allowed him to test and calibrate his touch screen to determine if it worked correctly.
This feature has been removed in the latest versions of Android. For most modern Android devices, the only option to calibrate your touch screen is to return to a calibration application from the Google Play Store.
A good application to test is the Touch Screen Calibration properly called. To get started, install the application from the Google Play Store. Then open the application and tap the “Calibrate” button in the center to start.
There are six touch tests that you can complete with a single touch pinch Follow the instructions on the screen and complete each test. When the test is finished, you will see a confirmation message.
Restart your device and use an application such as Touch Screen Test to see if there is any improvement.
If all else fails, perform a factory reset
If the touch screen still does not work properly after calibration, there could be underlying problems with Android that only a factory reset can solve. A factory reset is the nuclear option and you have no guarantee that it will solve any problem with your touch screen.

When you reset your Android device, all existing applications will be deleted and all caches will be deleted or settings that may be affecting the touch screen settings of your device. It can solve any delay in the touch screen that is a symptom of a larger problem. A device with large delay problems, for example, could be caused by the lack of available resources, which could solve a restart.
What it won’t do is solve hardware problems. If your touch screen is defective, even a factory reset will not solve the problem.
Performing a factory reset differs between phones and manufacturers, but you should find the option by going to Settings> System> Reset. Be sure to make a backup of your device first so you don’t permanently lose your data.
