Mi 13 is easy to scratch without a shell. Without the protection of a shell, the Mi 13's shell is vulnerable to scratches and collisions in daily use. Especially when placed in a pocket or in contact with other items, subtle scratches may occur. Therefore, users are advised to be extra careful when using the Mi 13 to avoid direct contact with hard objects, or they can choose to install a protective case or film to protect the phone's shell to reduce the risk of scratching. At the same time, regular cleaning of the surface of the phone can keep the appearance fresh and smooth.
