I just had an interesting thing happen.
I was reconfiguring my Home Screen and removed the Magnifier from the home screen. I just assumed I could get it back if I wanted to.
I decided I wanted to add it to Edge Panel. It wasn't listed. I then went to Apps in Settings, it wasn't there either. I did an App search and it was nowhere on my phone to be found.
I searched online and came across the same exact app as an APK download but security on my phone wouldn't allow me to install it.
I wound up getting it back by Restoring my Home Screen (and Apps) using Samsung Backup.
Why is this very handy Samsung (?) utility hidden and would there have been other ways to get that utility back?
