Hi, I ran out of storage on my s21 128gb. Why? Because media storage app is 40 GB heavy. This count only changes when Pics or Vids are added/deleted. In fact, every media is counted twice. Once in the DCIM, and once in media storage app. Samsung support doesn't help, claims it's "app data from Other apps" (???).
ARE YOU AFFECTED TOO?
For further description see linked thread.
@samsung: why isn't this being solved? It's been around for a while. It cannot be that you buy a 128 GB phone and (after systemspace) end up with less than half of that space!
I have a S21 Ultra with 256GB storage, Media Storage app is showing as using 32GB of storage space for me.
