Both of these devices include the same Android 11 operating system, so they should provide the user very similar OS features.

The Galaxy A51 features a much better camera than Galaxy Z Flip 5G, because although it has slower 30 frames per second video frame rate and a tinier aperture which is not nice for low light photography and video, and they both have the same video resolution, the Galaxy A51 also counts with a way larger sensor providing a lot better image quality and a much more mega-pixels camera.
