The Samsung A12 also has multiple pages for apps. To move them you just hold the icon until it allows you to move it wherever you want - up, down or horizontally on to any number of pages. There's also the option of removing them from any screens and storing them in the apps folder (or any folder you create)
I think the amount of apps/junk etc pre-loaded probably has to do with the jurisdiction or provider. Mine was pretty much blank out of the box except for the preloaded Samsung and Google Apps.
The thing I enjoy about Android phones (I have mac computers and an ipad) is that you can easily get deep inside and mess with the files if you want.
The thing that annoys me most is that after (compulsory) system updates, some settings are changed or permissions previously denied are opened.
I go
through all my apps and deny any but those absolutely necessary for using the app so when I discover permissions re-allowed it peeves me. Not sure if ios updates do that.
