Why is there a scratch on the middle frame of the Xiaomi 15 Ultra?

The middle frame of the Xiaomi 15 Ultra is crafted from high-quality metal, which is cut from a single, solid piece of material. During the production process, slight marks or scratches can occasionally appear due to the precision cutting and handling of the metal. These marks are typically minor and often occur as part of the manufacturing process.
It's important to note that these marks are purely cosmetic and do not affect the overall quality, strength, or functionality of the device. Additionally, the Xiaomi 15 Ultra undergoes a comprehensive inspection and quality control process before it is released for sale. This ensures that the device meets Xiaomi's reliability standards and industry regulations. Please rest assured to use it.
