Thank you for your support of Xiaomi products. The phone will undergo strict professional inspection before leaving the factory, and you can use it with confidence. If the screen is set to a lower resolution, some elements will appear less sharp or slightly pixelated. In order to improve the clarity of the displayed content, you can try to manually adjust the screen resolution to WQHD+, which will alleviate the problem. Certain third-party apps are not fully optimized for high-resolution displays, leading to unclear UI elements. This is especially common in apps that have not yet been updated for WQHD+ resolution. If the issue is app-specific, ensure that your applications are updated to the latest versions. Some apps will have rendering bugs that are resolved in newer updates.
