Thank you for your support of Xiaomi. The Xiaomi 15T Pro primary camera sometimes displays a grayish tint when first used with third-party camera Apps. This can happen during initial use, especially when switching between different Apps or shooting in varied lighting conditions.
The gray appearance is temporary and is more noticeable in scenes with low light or high contrast. This occurs due to differences in image processing when the device is first used with third-party Apps.
Updating the device to the latest stable system version will resolve this issue. After updating, photos taken with third-party Apps will consistently show natural colors and accurate image quality, providing a smoother and more reliable imaging experience across different scenarios.
