Why does the back cover joint of the dual-color version Xiaomi 15 Ultra look not straight?

The dual-color version of the Xiaomi 15 Ultra features an innovative design that combines silver spray and leather materials to create a unique and modern aesthetic. To ensure the design flows seamlessly, we decided to adopt a micro-curved bevel at the back cover joint rather than the conventional straight-line stitching typically used in traditional designs.
This choice was made to achieve a more natural edge transition between the two materials, providing a smoother and more harmonious visual effect. The curved bevel not only enhances the overall aesthetic appeal of the phone but also helps in creating a balanced, premium look that highlights the dual-material structure. This design approach is specifically intended to emphasize visual beauty and elegance while maintaining a high level of craftsmanship. Thank you for your support for Xiaomi.
