In the MX Player application, a new feature was introduced where, during music playback, the player switches to a new theme. The goal was to move away from the old, simple interface to a more user-friendly environment.

However, what actually happens is that once you enter this new environment, the entire application changes—not just the appearance. For example, the way you access files and how they are categorized is also altered.

Let’s say a song is playing—you can no longer figure out how to return to the folder where the song was originally played from. Also, the categorization of music by folders is completely different, and in most cases, you can’t find the song you’re looking for.

In this case, it would have been better if only the music playback interface had changed, while the file directory environment remained the same. Alternatively, the app could have asked for user confirmation before applying such changes, so users wouldn’t get confused when trying to play their music.

Most users organize their music files manually, so the file access section should have retained the previous design—or the changes could have been rolled out gradually over several updates, allowing users time to adjust.
