Why Ghost Touch Happen

Do you find virtual entities leaving footprints on your smartphone screen that weren't made by your flesh-and-bone fingers? Do apps randomly open, ghost calls made, unwanted texts sent or the screen scrolls up and down seemingly without your help? Well, you are not alone. This is commonly referred to as "ghost touch".

What is Ghost Touch?

Ghost touch is a term used to describe the phenomenon where a touchscreen device responds to input that was not actually made by a user. This can manifest itself in a variety of ways, such as the screen registering phantom touches, swipes, or taps, or apps opening or closing without being prompted.

What Causes Ghost Touch?

The causes of ghost touch can be broadly classified into two categories: hardware issues and software glitches.

Hardware Issues

  1. Faulty Touchscreen Digitizer: The touchscreen digitizer is a transparent layer on top of the display that detects the electrical signals generated by your finger when you touch the screen. If the digitizer is damaged or malfunctioning, it can lead to ghost touches and other erroneous inputs.
  2. Electromagnetic Interference (EMI): Electromagnetic interference from external sources, such as power lines, Wi-Fi routers, or even other electronic devices, can disrupt the functioning of the touchscreen and cause ghost touches.
  3. Moisture: Water or other liquids coming into contact with the touchscreen can also lead to ghost touches, as the touchscreen may misinterpret the presence of moisture as input from a finger.

Software Glitches

  1. Operating System (OS) Bugs: Software updates and new OS versions can sometimes introduce bugs that can cause ghost touch issues. These bugs can affect the way the touchscreen is calibrated or how it processes input.
  2. App Incompatibility: In some cases, ghost touch can be caused by incompatible or poorly designed apps that interfere with the functioning of the touchscreen.

How to Fix Ghost Touch

  1. Restart Your Device: A simple restart can often resolve ghost touch issues caused by temporary software glitches.
  2. Update Your Device's OS: Installing the latest software updates for your device can fix ghost touch issues caused by OS bugs.
  3. Disable Problematic Apps: If you suspect that a particular app is the cause of ghost touch, try disabling it to see if the issue persists.
  4. Calibrate Your Touchscreen: Most devices have a built-in touchscreen calibration tool that can be used to correct any misalignment or sensitivity issues that may be causing ghost touches.
  5. Protect Your Device from EMI: Keep your device away from sources of electromagnetic interference, such as power lines and Wi-Fi routers.
  6. Avoid Using Your Device in Wet Conditions: If possible, avoid using your device when it is raining or in humid environments, as moisture can trigger ghost touches.
  7. Contact a Repair Technician: If the issue persists, you may need to take your device to a repair technician to have the touchscreen or other faulty components replaced.

Preventing Ghost Touch

  1. Use a Screen Protector: A screen protector can help protect the touchscreen from damage and reduce the risk of ghost touch caused by external factors.
  2. Keep Your Device Clean: Regularly clean your device's screen with a soft, lint-free cloth to remove dirt, dust, and oils that can interfere with the touchscreen's functionality.
  3. Avoid Touching the Screen with Wet or Dirty Fingers: Make sure your hands are clean and dry before using your device's touchscreen, as moisture and dirt can cause ghost touches.
  4. Install Antivirus Software: To protect your device from malware and other malicious software that may cause ghost touch issues, install a reputable antivirus app.


Ghost touch can be a frustrating and confusing issue, but it can usually be resolved by following the steps outlined above. If the problem persists, it is best to consult a qualified repair technician for further assistance.
