Why is there a gap between the glass back cover and the frame of the Xiaomi 15?

The Xiaomi 15 features a glass back cover paired with a metal frame, creating a bright and reflective visual effect. While the design has been carefully crafted to seamlessly integrate these materials, unavoidable differences in light reflection can make the gap appear more noticeable from certain angles. However, all devices undergo strict quality inspections before leaving the factory, so you can use your phone with confidence.
