How to Fix an Unresponsive Touch Screen

By Melissa King

Many of today's electronic devices -- including cell phones, music players and portable game systems -- have a touch screen. When a touch screen fails, it does not respond when you tap it with your finger or a stylus. This can happen due to several reasons, such as a screen protector, dust or improper calibration. You can often fix an unresponsive touch screen by cleaning it or resetting the device.

Things You'll Need

  • Microfiber cloth

Step 1

Remove the plastic touch screen protector sheet. Some protector sheets are too thick and prevent the touch screen from responding to your touch. If you must use a protector screen, only use one that is licensed for your specific device.

Step 2

Wipe the screen with a soft microfiber cloth. Clean off any dirt, dust or fingerprints on the screen.

Step 3

Dry your hands thoroughly. The touch screen will not respond if your hands are wet.

Step 4

Reset the device. If your device does not have a "Reset" button, remove the battery, memory card or SIM card, then reinstall them.

Step 5

Delete any third-party applications you recently installed. Some third-party applications can cause your device to lock up or freeze.

Step 6

Recalibrate the touch screen. Look in the device's Settings menu for a calibration option and follow the prompts.

Tips & Warnings

  • Contact your device's manufacturer if you cannot repair the unresponsive touch screen. The device may need professional repair. If the device is covered by a warranty, you can usually receive a free or discounted repair.
  • Take off gloves before you use a touch screen. Touch screens respond to your finger's warmth, and gloves block the warmth from reaching the screen.
