I tried to uninstall something called kies air that looks like something of no interest or use to me. I touched apps in the lower right corner then menu lower left then uninstall in the popup menu. The screen adjusted itself into a box but when I touch the kies air icon nothing happens. Then I swiped over a couple of screens and found some I downloaded that had a minus sign indicating I could uninstall them. There are over 2 pages that can't be though. I'm sure some of it is just junk taking up space and potentially slowing the system. Is there a way to uninstall stuff like that? Thanks.
