Thank you for your support of Xiaomi. In certain cases, the zoom preview in Portrait mode on the Xiaomi 15T Pro sometimes appears momentarily slow. This occurs when multiple Apps are running in the background or when many photos are captured in quick succession.
Under such conditions, the camera temporarily consumes more system memory, which can lead to a brief delay in preview responsiveness. This behavior is normal and occurs due to temporary high memory usage during continuous shooting.
To ensure an optimal experience, please refer to the following information:
Update to the latest system version for performance improvements.
Avoid taking a large number of photos in a short period, especially in front-facing portrait mode.
After capturing photos quickly, wait briefly to allow the phone to complete image processing before taking the next shot.
