Why do the microphone hole and pressure relief hole of the Redmi Note 13 Pro+ 5G look out of round?

The Redmi Note 13 Pro+ 5G is designed with precision to ensure an elegant and uniform appearance. To maintain a sleek look, the side openings on the middle frame are aligned horizontally. The top microphone and pressure relief holes use an oblique angle design. This design choice means that when viewed from certain angles, especially on the light-colored middle frame, the side walls of the holes are visible, giving the illusion that the holes are out of round. However, this is a normal design feature and does not affect functionality. You can confidently use your device without any concerns about this aspect of its design.
