Fingerprints

Touchscreens can suffer from the problem of fingerprints on the display. This can be mitigated by the use of materials withoptical coatingsdesigned to reduce the visible effects of fingerprint oils, oroleophobiccoatings as used in most of the modern smartphones, which lessen the actual amount of oil residue, or by installing a matte finish anti glare screen protector, which creates a slightly roughened surface that does not easily retain smudges, or by reducing skin contact by using a fingernail or stylus.
