Types of Reset and Calibrate Touch Screen Issues
Touch screen problems can manifest in various ways. Understanding the type of issue you’re dealing with is the first step towards fixing it. Common touch screen issues include:
- Unresponsive Screen: The touch screen does not respond to any touch input.
- Delayed Response: The screen responds to touch, but there is a noticeable delay.
- Ghost Touches: The screen registers touches that you did not make.
- Dead Zones: Specific areas of the screen do not respond to touch.
- Erratic Behavior: The screen behaves unpredictably, such as opening apps on its own.
Common Causes of Reset & Calibrate Touch Screen
Several factors can lead to touch screen issues on Android devices. Identifying the cause can help in choosing the right solution:
- Software Glitches: Bugs in the operating system or apps can cause touch screen problems.
- Physical Damage: Cracks, water damage, or wear and tear can impair the touch screen.
- Dirt and Debris: Accumulation of dust, dirt, or oils can interfere with screen sensitivity.
- Hardware Faults: Internal hardware issues, such as a faulty digitizer, can affect touch performance.
- Incorrect Settings: Misconfigured settings or accessibility options may impact touch screen functionality.
Preliminary Troubleshooting
Before diving into resets and calibrations, it’s essential to perform some preliminary troubleshooting steps. These basic checks can often resolve minor touch screen issues.
Restarting Your Device
Restarting your device can resolve many temporary glitches. To restart:
- Press and hold the power button until the power menu appears.
- Select “Restart” or “Reboot”.
- Wait for the device to restart and check if the touch screen issue persists.
Checking for Software Updates
Ensuring your device is running the latest software can fix bugs and improve performance:
- Go to Settings > System > Software Update.
- Tap on Check for updates.
- If an update is available, follow the on-screen instructions to download and install it.
- Restart your device after the update is complete.
Safe Mode Diagnosis
Booting your device into Safe Mode can help determine if a third-party app is causing the touch screen issue:
- Press and hold the power button until the power menu appears.
- Tap and hold “Power off” until the “Reboot to Safe Mode” prompt appears.
- Select “OK” to restart in Safe Mode.
- Check if the touch screen works properly in Safe Mode. If it does, a third-party app is likely the cause.
To exit Safe Mode, simply restart your device.
Resetting Your Android Touch Screen
If preliminary troubleshooting doesn’t resolve the issue, resetting your touch screen may help. There are several types of resets you can perform.
Soft Reset
A soft reset is a simple restart of your device, which can resolve many minor issues:
- Press and hold the power button.
- Select “Restart” from the power menu.
- Wait for the device to restart and check the touch screen.
Hard Reset
A hard reset, also known as a force restart, can be useful if your device is unresponsive:
- Press and hold the power button and the volume down button simultaneously until the device restarts.
- Release the buttons once the manufacturer logo appears.
- Check the touch screen after the device has restarted.
Factory Reset
A factory reset will erase all data on your device and restore it to its original settings. This is a last resort if other resets fail:
- Backup your important data.
- Go to Settings > System > Reset > Factory data reset.
- Follow the on-screen instructions to confirm the reset.
- Once the reset is complete, set up your device and check the touch screen.
Calibrating Your Android Touch Screen
If resetting your device does not resolve the touch screen issues, calibration may be necessary. Calibration adjusts the touch screen settings to improve accuracy and responsiveness.
Using Built-in Calibration Tools
Some Android devices come with built-in calibration tools. To access these tools:
- Go to Settings > System > Developer options.

Note: Developer options must be enabled to access these tools. To enable Developer options:
- Go to Settings > About phone.
- Tap on Build number seven times until you see a message confirming Developer options are enabled.

Third-Party Calibration Apps
If your device does not have built-in calibration tools, you can use third-party apps available on the Google Play Store:
- Open the Google Play Store.
- Search for “touch screen calibration”.

- Download and install the app.
- Follow the app’s instructions to calibrate your touch screen.
Advanced Calibration Techniques
For advanced users, manual calibration through adb (Android Debug Bridge) can be an option:
- Enable USB debugging on your device: Settings > System > Developer options > USB debugging.
- Connect your device to a computer with adb installed.
- Open a command prompt or terminal window on your computer.
- Enter the command
adb shell wm size
to check the screen resolution. - Enter the command
adb shell wm density
to check the screen density. - Adjust the screen size and density if necessary using the commands:
adb shell wm size <width>x<height>
adb shell wm density <density>
- Reboot your device and check the touch screen.
Maintaining Your Touch Screen
Regular maintenance can prevent touch screen issues and extend the life of your device.
Regular Software Updates
Keeping your device’s software up to date ensures you have the latest bug fixes and performance improvements:

Screen protectors can protect your touch screen from damage while maintaining touch sensitivity:
