Consistent buffering issue on Android for large videos, reproducible across multiple devices

On Android mobile devices, a video file of approximately 400 MB fails to play properly.
Even without any transcoding applied, the player remains stuck in a continuous loading (buffering) state, making the video unwatchable.

In contrast, the same video loads and plays extremely fast in web browsers without any issues.

This behavior is consistently reproducible across multiple Android devices, as all family members experience the same problem on their smartphones.
