One big issue nobody talks about or is completely unaware about is that everytime you download or store any media like movies, not only does the original space of the movie gets occupied, the media storage app in the phone magically increases the exact same amount of storage usage. You could verify it yourself by going into storage and select the view system apps option. So for example if you download a 2 gb movie, instead of going from 62-60gb storage space, it goes from 62-58gb storage space. This is very big issue which is also faced by many OnePlus devices. You cannot force stop the media storage app or delete any data or cache in it. The only temporary solutions which worked for some is deleting the recycle bin data, clearing unwanted data using files app and maybe resetting your device but the fact that this issue exists is a huge problem and is still unresolved for many users. I hope someone might be able to solve this issue or could at least help make realme aware about this issue.
