Why are the four rounded corners of the REDMI Note 14S frame irregular?

Thank you for your continued support. The REDMI Note 14S has undergone strict professional inspection before leaving the factory, so you can feel confident in the performance and reliability of your device, knowing that it has been thoroughly tested for quality and functionality.
The phone's middle frame casing features a metallic-look spray paint finish and is manufactured using in-mold injection molding technology with a four-sided sliding mold process. Due to this production method, slight parting lines can appear in the four corner areas, and polishing in the corner regions will have blind spots, leaving minor residues. This is a normal phenomenon that does not affect the appearance or usage.
