Do not use ammonia-based cleaning products, window or glass cleaners, rough cloths or paper towels.
Use A Protective Screen Film
Screen film is thin and transparent with a stick-on side that can be applied on the surface of the screen. This will help protect it from the usual problems associated with regular wear-and-tear, such as scratches (which will also eliminate the need for Samsung Galaxy S4 LCD replacement scratch repair).
