Over time, the touch screen of your Android device could start to weaken. Before you consider replacing your device, you must see if the calibration of the touch screen can solve the problems. Here's how to recalibrate your Android smartphone or tablet.

Does your touch screen need to be calibrated?

As Android has evolved and developed over the years, the hardware on which it runs has also evolved. The Android hardware is today much better and more powerful than previous generations.

Modern Android touch screens rarely require the user to calibrate or otherwise configure it. Touch screen faults are more likely to be caused by hardware problems that can not be solved than by a particular configuration problem.

However, calibration should not be completely excluded as it may be useful in some circumstances.

For example, this may be a good way to adjust the sensitivity of your touch screen, especially if something else impacts it. Some types of screen protectors, for example, can affect the performance of your touch screen. This is a problem that a calibration can sometimes improve.

It's also good to try this on older devices where the technology was not as advanced and where calibration can have a bigger and more visible impact. Calibrating a touch screen is not a problem, regardless of age, but older devices will probably benefit more.

Test your screen

Before you start, you need to know if the touch screen of your Android device is in perfect working order.

Older versions of Android included secret menus and development options that allowed you to test and calibrate your touch screen. This was important on older Android devices, while modern touch screens were still in their infancy.

If you have an old Android phone, you can try to access this secret touch menu by dialing * # * # 2664 # * # *. This option will not work on Android devices from Android 5 Lollipop.

For modern Android devices, applications are available in the Google Play Store this will allow you to test the touch screen instead. These will show you the answers to your contact on the screen, allowing you to determine if the screen is correctly calibrated or not. A good option to try is Touch screen test.

It's easy to use. Install it and touch the screen wherever you want.

Like a brush, the application saves the white dots on which your fingers are pressed. If the answers are staggered or unsynchronized, this indicates a problem with your screen that the calibration might resolve as a first resort.

Calibrate your touch screen

As we have mentioned, older versions of Android included built-in calibration tests. These tools allowed you to test and calibrate your touch screen to determine if it was working properly.

This feature has been removed in newer versions of Android. For most modern Android devices, the only option to calibrate your touch screen is to return to a calibration app from the Google Play Store.

A good app to try is the aptly named Calibration of the touch screen. To get started, install the app from the Google Play Store. Then open the app and press the "Calibrate" button in the center to begin.

Open the calibration application of the touch screen and press Calibrate.

You have six tactile tests to perform, from the simple tap to the pinch. Follow the instructions on the screen and complete each test. When the test is complete, a confirmation message is displayed.

When calibration is complete, restart your device.

Restart your device and use an application like Touch screen test to see if there are any improvements.

If all else fails, perform a factory reset

If the touch screen still does not work properly after calibration, there may be underlying issues with Android that only a factory reset can resolve. A back to factory settings is the nuclear option and has no guarantee that it will solve the problems associated with your touch screen.

Resetting your Android device will remove all existing apps and clear any caches or settings that may affect your device's touch screen configuration. This could solve the delays of the touch screen which are the symptom of a larger problem. A device with significant delay problems, for example, could be caused by a lack of available resources, which a reset might fix.

What he will not do is solve hardware problems. If your touch screen is faulty, even a factory reset will not solve the problem.

Resetting factory settings varies by manufacturer and handset, but you should find the option by selecting Settings> System> Reset. Make back up your device first, not to lose your data permanently.
