You have to use a replacement launcher like nova. There are others but try the free version first to see if you like the way the wall paper display and such...I don't think all the launchers work well with the dna"s screen resolution.
there is a setting to remove icon titles in the set up...if not in free versions some will have it in paid version...nova has been worth every penny so far. Some folder apps will let you rename apps, like folder organizer, and I will just use a period if I have a black background, this makes words not show up...simple text lets me name apps with a word title only which I really like as seen on my image...each word is an app or shortcut with swipe actions available also.
