Why does the portrait mode on the Redmi Note 14 Pro not show the blur effect when previewing photos?

Thank you for your support for the Xiaomi product. We apologize for the inconvenience. The blur effect in portrait mode is actually achieved through software post-processing. When taking a photo, the phone uses depth perception to determine the distance difference between the foreground and the background and blur the background. This blur effect is generated after the photo is taken and will not be fully presented in the real-time preview. This is not a quality issue of the product, you can feel free to use it. Please ensure that your phone is running the latest software version by checking for updates in the settings.
