This error occurs when you have sticked a screen protector on the screen of the Samsung Galaxy S5. If there are any liquids at the screen protector such as sweat then it may come to that malfunction of the touch display. This malfunction is favored if there are already cratches etc. present on the screen protector.
To solve the problem, you can either clean the screen protector with a cloth or remove it and apply a new film, which is not yet damaged.
