matt is not shiny.."no" fingerprint.
Gloosy are hi reflectance. finger print mark prone.
Those shop that applied Sp will do it for you at S$10.
matt also makes your screen significantly dimmer, visible rainbow effects, and basically makes your screen look like a pixellated tv from the 90s.
but yes, fingerprints are less visible. Also, cuts down on glare when you're outside.
