Is it possible that your phone cannot play MP4 files? Try playing the files with the VLC player app from VideoLan. It does not work with another phone either.

Do you see the files in the app, but you cannot start them or do you not see them at all?

If you want to play them, did you download them first? Or do you watch the recordings directly via the app from the camera?

If you get an error message on the screen, what is it?
