The REDMI Note 14 uses a combination of high-quality materials for durability and a premium feel. The back shell material is PC + PMMA. The combination of PC (Polycarbonate) and PMMA (Polymethyl methacrylate) in the back shell makes the device resistant to impacts and scratches. PMMA adds a glossy, high-quality finish, giving the phone a sleek, premium appearance. PC enhances the overall strength, providing robustness to the device, while also maintaining a lightweight profile. The middle bezel is made from PC, which contributes to the phone's structural integrity. Polycarbonate is a tough, lightweight material that helps the device resist impacts, while maintaining transparency for a clean, minimalist aesthetic. The lens protection glass is made from PANDA-X and GG3, ensuring durability and resistance to scratches. The physical button material is PC. However, it doesn’t support touch button light and the rear shell is not removable.
