Like any electronic device, your Android device may eventually start to malfunction. This can manifest itself in different ways, but quite often the problem starts with the touch screen. At first, you’ll find that the response to the commands you give the touchscreen lags.
Over time, the delay will grow and if you do nothing, you may find that the screen will completely ignore all touches. However, even if you haven’t taken any action in time, check to see if a touchscreen calibration can fix any issues before replacing your device.
Here’s how to calibrate your Android smartphone or tablet.
How do you can use Android functions to perform touch screen calibration
Android, like its competitors on the market, has improved and evolved. The hardware on which it runs is also much better and more capable than previous generations.
For this reason, in most cases, modern Android touch screens don’t require the user to calibrate or otherwise configure them.
If you encounter a problem when using a smartphone screen running on Android, it’s most likely caused by hardware problems. In such cases, the issue cannot be solved by manipulating configurations.
Nevertheless, don’t rule out calibration completely. Calibration can be useful in some circumstances.
For example, it can be used to adjust the sensitivity of the touch screen, especially if it’s affected by something else. For example, some types of screen protectors can impact touchscreen performance. Calibration sometimes helps to solve this problem.
If we’re talking about older devices, where the technology wasn’t so advanced, then the calibration can have a stronger and more noticeable impact.
How you can find out, do you need to calibrate your touch screen or not
Before you get started, make sure your Android device’s touchscreen is in full working order
If you own an older version of Android, you can use the secret menus and developer options to test and calibrate the touchscreen.
If you own an older Android phone, you’ll dial ##2664## to access the secret menu. This option won’t work on Android devices starting with Android 5 Lollipop.
As mentioned above, there are no such menus on modern phones. Instead, you can use special apps in the Google Play Store, which will allow you to test the touch screen.
They’ll show the response to touching the screen, which will help you determine if you need to calibrate the screen or not. A good option for testing is Touch Screen Test. It’s easy to use. Set it up and touch the screen anywhere you like.
Once you install this app and turn it on, it’ll work like a paintbrush. The app will start recording white dots where your fingers are tapped. If the responses are lagging or out of sync, this indicates a problem with the screen, which can first be corrected with a calibration.
How to use Touchscreen Calibration app to fix your touch screen on Android
In order to calibrate the touchscreen on new devices, as you have already read above, you need to use a special application.
Using the example of Touchscreen Calibration, which is free and available for download from the Google Play Store, see how exactly you can do this. To do this:
- First, install and run the Touchscreen Calibration app.
- After launching the app, click the “Calibration” button.
- Follow the instructions on the test bar in the app. Continue until your device passes all tests.
- Once you have completed the tests, you’ll receive a notification that the calibration is complete.
- Click the OK button.
How to fix your Touchscreen on devices up to Android 4.0
Android devices up to Android 4.0, Ice Cream Sandwich, had a built-in calibration option. Depending on the device and Android version, the location of this setting varies, but usually, the procedure is as follows:
- Unlock your phone and find “Settings”.
- In Settings, find the “Language and Keyboard” section.
- Next, select “Touch Input”.
- After that, select “Text Input”.
- Under “Finger touch precision”, tap “Calibration tool” or “Reset calibration”.
This way you can use the built-in function to calibrate the sensor.
