Sorry for the poor explanation... On the J3 2016.. apart from the icons on the front screen, if I swipe right I then have another screen with more app icons, etc.
All my other Galaxy phones always had swipe right and swipe left to get to the other app icons The J3 2017 only seems to have swipe down for some reason and I am not sure if it is a bug or can be changed to swipe right and swipe left
