Why does a phone storage being exhausted while still have space?

[Stardom22]

I had a phone some couple of years ago. The phone was really annoying because it used to tell that not enough space in your phone while when you look so closely you find like 2GB of storage space just lying idle over the phone. Has anyone here experienced the same thing ever?

I have not experienced it. Maybe your phone has a low memory. That's one factor why can't load more despite you see it space available. You could have upgraded your phone.

It is possible that there are some hidden files taking up space or maybe the chacha is full and needs to be deleted.
