A screen guard is essential for many reasons and it also boosts the usability of these electronic devices. These shields protect from the day to day usage such as scratches by keys or other items in pockets or bags. Most screen protectors also have a shatterproof design, making sure that even if the phone is dropped in any accident, it does not put cracks on your phone-s ear. Moreover, they have oleophobic layers that prevent fingerprints and smudges allowing you to always see your screen clearly. More advanced protectors even provide some privacy protection by limiting the viewing angle so that those around you cannot view what you are seeing on your screen. They are easy to apply, remove residue-free, and replace whenever protectors are due for an upgrade or replacement.
