If the touchpad isn't properly calibrated, actions may be delayed, inaccurate, or even uncomfortable when using the device.
Additionally, improper calibration can cause apps to not respond as they should, the keyboard to not register letters properly, or you may experience difficulty playing games, typing, or even browsing your phone. Therefore, learning how to calibrate your Android's touchscreen for free can save you money and time, avoiding unnecessary visits to the technician.
When is it advisable to calibrate the touch screen?
The decision calibrate the screen should be based on the observation of recurring problems.

How do you know if your touchscreen is failing or if it's a software problem?
Before you start calibrating, it is important to differentiate whether the source of the error is hardware (for example, physical damage to the panel) or with (such as application conflicts or system processes). Here's a quick step-by-step guide to help you diagnose the source:
- Examine physical condition: Check the screen for cracks, smudges, scratches, or any other visible damage. If there are only visual issues but touch response is still working, it may be just the LCD.
- External monitor: If you can connect your phone to an external monitor or use it with peripherals, determine if only the touch pad is damaged and not the image.

- Pending updates: Keeping your operating system up to date is critical, as many updates fix bugs that can affect the touchscreen.
How to perform a touchscreen test on Android
Before calibrating, it is advisable perform a screen test to identify problem areas and confirm the presence of ghost touches, lag, or dead zones. You can do this in several ways depending on your Android version and manufacturer:
- Internal tools: On some phones you can access hidden menus or diagnostic tools by entering the secret code in the phone app. * # * # * # * # 2664This will open a native test to verify touch response.
- Development options: Enable Developer Options by going to Settings > About Phone > tapping Build Number. Then, go to Settings > Developer Options > enable Pointer Location. Lines and strokes will appear showing the path of your taps so you can identify any unresponsive areas on the screen.
- Search by touch sensitivity: On some phones, go to Settings and look for the “Touch Sensitivity” or similar option and activate it to increase sensitivity when using screen protectors.
If your device doesn't have these options, there are free applications that allow you to perform screen tests and detect defective areas.
