That's a nice device! What small icons you have! What launcher are you using. I've been using the Nova Launcher. I love that you can customize it so much. There seem to be endless options! I don't keep my icons so small though. I have a 5x6 grid, not counting the tray at the bottom. I wish I could get my phone rooted. I have the Galaxy S7 SM930U. It's virtually impossible to root.
