The touch screen responds slowly or improperly

If your phone 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 phone from recognising your inputs and are not recommended for touch screen phones.

•Depending on the type of touch screen on your phone, only certain inputs may be recognised. Try tapping an icon with your fingertip, your fingernail, or a stylus.

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

•Restart your phone to clear any temporary software bugs.

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

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