Core Function Highlights Military-grade drop protection, four-fold protection system Flexible and rigid material combination: the outer layer is PC hard shell to resist sharp impacts, and the inner layer is TPU soft rubber to absorb the impact of the fall, which is tested to be undamaged by a 2-metre fall, and the impact resistance is increased by 300%. Corner honeycomb airbags + lens screen height protection: the lens frame is 1.5mm higher than the screen, anti-scratch and anti-crack; the top arc airbag design makes it more comfortable to hold horizontally and slows down the impact of falling. Anti-magnetic interference black technology, signal worry-free Nano Anti-Magnetic Coating: Built-in 3 layers of electromagnetic shielding material, effectively isolate the external magnetic interference, to avoid magnetic accessories affecting the phone's compass, NFC, wireless charging and other functions. Signal Penetration Optimisation: The back panel is made of non-metallic anti-magnetic material, which does not shield 5G/Wi-Fi signals and ensures a stable network connection. Material and process details Carbon Fibre Texture + Liquid Silicone Lining: The back panel is designed with carbon fibre texture, which is abrasion-resistant and fingerprint-resistant; the inner part is made of skin-like liquid silicone, which is soft and skin-friendly, and prevents scratches on the back cover of the phone. Anti-fouling oleophobic coating: The surface is covered with a lotus leaf-like oleophobic coating, which is waterproof and sweatproof, and is as good as new. Individual key design: Sensitive key feedback and moderate key stroke to avoid accidental contact or effortful pressing.
