Why doesn’t the Xiaomi 15 camera interface display in landscape mode when mirrored to a TV?

By design, the camera interface on the Xiaomi 15 is displayed in portrait mode, and when mirrored to a TV, it maintains the same orientation. This is because screen mirroring replicates the exact layout shown on the phone’s display without altering the aspect ratio or orientation. The camera interface is optimized for handheld use, where portrait mode provides a more convenient layout for accessing controls, taking selfies, and making video calls. Unlike media players or certain APPs that adjust to fit a larger screen, the camera interface remains fixed in portrait mode to ensure a consistent using experience. If you want to view captured photos or videos in landscape mode on a TV, you can do so through the gallery or a media player after recording.
