Samsung S10 Lite Screen Protector SM-G770F Pack of 2x Tempered Glass

Which screen protector?

Tempered glass is stiff and feels like the phone's own screen, and it takes knocks well. Hydrogel film is thin and flexible, so it wraps round curved edges where glass can lift. Privacy protectors darken the screen when viewed from the side, so people next to you can't read it.

Screen sizes and camera cut-outs differ even between similar models, so match the exact model name of your phone.
