Material: Typically made from a hybrid of flexible TPU (Thermoplastic Polyurethane) for the bumper and a hard PC (Polycarbonate) back for impact resistance.
Protection: Includes reinforced corners (often with air-cushion technology) to absorb shock from drops and raised bezels (approx. 2.5mm for the camera and 1mm for the screen) to prevent surface scratches.
Design: Features precise cutouts for speakers, chargers, and the camera array, ensuring full functionality without removing the case.
Durability: Many models use a "Nano antioxidant" layer to resist yellowing over time from sweat and skin oils
