Samsung A50 compass and tidying UI query

1) Is the compass on the Samsung A50 accurate or does it rely on GPS Satellites?
2) Is there any way to make an "Image" copy of a Samsung A50 and then restore it if you mess up the UI (see 3 below)?
3) How easy is it to "clean up" the Samsung A50 display by deleting unwanted Apps - i.e. most of them?
