Precise button holes and unobtrusive touch: openings fit accurately so button feedback remains natural; all device functions operate normally, and neither radio reception, heat dissipation, nor sensor performance is affected. scratch resistance: the film surface hardness reaches 9H, delivering about three times higher scratch resistance than standard films and providing protection against scratches from keys and other objects. lens cover and protective case: both are made from food grade silicone, soft and elastic, able to absorb impacts and cushion the device from bumps. Accurate hole adaptation with real device molding: crafted to reserve front and rear screen cutouts, microphones, loudspeakers, color temperature sensors, and other functional holes with a toleranced accuracy within ±0.1 mm. Designed for reliable compatibility and fit: tailored to match the device's precise layout and features, ensuring seamless access to all controls and sensors without modification. Use scenarios: Daily commuting and office work: protects screens and components while typing, swiping, and using sensors in everyday tasks. Outdoor and travel activities: provides impact absorption and edge protection when on the move, reducing risk of screen or camera damage. Educational or workshop environments: preserves device usability with easy access to microphones, speakers, and temperature sensors during handson tasks.
