Material Types: Tempered Glass: These are thicker and provide better protection against scratches and impacts. They usually have a smooth feel and are highly transparent. Plastic Film: Thinner and more flexible, plastic film protectors are less noticeable on the screen but may not offer as much protection against impacts. Features: Anti-Glare: Some screen guards have anti-glare properties to reduce reflections and improve visibility in bright conditions. Privacy Filters: These screen protectors limit the viewing angle, making it difficult for others to see the content on your screen. Installation: Adhesive Type: Screen protectors can be adhesive-based (using a sticky layer) or static cling. Follow the manufacturer's instructions for a bubble-free application. Compatibility: Ensure that the screen protector is designed specifically for your iPhone model to align with the camera, sensors, and other features accurately. Coating: Some screen protectors come with additional coatings, such as oleophobic coatings to resist fingerprints and smudges. Full Coverage vs. Edge-to-Edge: Full-coverage protectors cover the entire front surface, while edge-to-edge protectors extend to the phone's edges for additional protection. Thickness: Thickness can vary, and some users prefer thinner protectors for a more natural feel. Durability: Consider the durability of the screen protector in terms of scratch resistance and impact protection.
