The touch screen responds slowly or improperly

If your device has a touch screen and the touch screen is not responding properly, try the following:

•Remove any protective covers from the touch screen. Protective covers may prevent the device from recognizing your inputs and are not recommended for touch screen devices.

•Ensure that your hands are clean and dry when tapping the touch screen.

•Restart your device to clear any temporary software bugs.

•Ensure that your device software is upgraded to the latest version.

•If the touch screen is scratched or damaged, take it to your local Samsung Service Center.
