How to Fix an Unresponsive Touch Screen

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.

Step

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

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

Step

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

Step

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

Step

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

Step

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