No app icons on home screen for newly installed apps in Galaxy Tab S 10.5 My Samsung Galaxy Tab S 10.5 running Android 4.4.2 is not creating app icons for newly installed apps, I have checked the settings in Play Store, and they are correct.  What's wrong, and how do I correct it?
Have you checked to see if your tablet started a new homepage?  I have a SGT-S 8.6" Wi-fi (T-700). When I started using mine I noticed that it will put new icons on a new page even when there is room on the first page.  

On your homepage; bottom center, above the app tray symbol (circled dots), there are dots in a row indicating which home page you are currently using and how many pages there are.  If you are using the Google Now launcher it's page will also have it's own dot to the left off the one you are on.  If there is another dot just swipe left to go to the next page.  Now you can drag your new icon to your homepage and drop it where you want.  You might want to check into grouping your icons into folders.
Here it's a link to the manuel:
