Prevent Android From Adding Icons to Home Screen
A well-organized home screen is a thing of beauty . When you download a new app from Google Play, it adds an icon to your screen, destroying your artwork. A quick setup in the Google Play app solves this problem.
Go to the Google Play app, then go to its settings with the three-line hamburger icon. Uncheck Add Icon to Home Screen. You will still add app icons manually, but they will not be added automatically when you download the app.
