On every other Android phone or tablet I've used, if I install a new app, then the icon for that app is added to one of the existing home-page screens if they have space. On this Samsung T580 Tab 10.1 I find that despite page 1 having a few icon spaces free, and page 2 having even more free, it feels the need to create a new 3rd page and put the icon there.
So every time I install a new app I have to swipe along to the 3rd page, long-press the icon and drag it to the 1st or 2nd page, then go back and delete that 3rd page.
I haven't tried leaving one icon on the third page and installing another app to see if I get a 4th page but I wouldn't be surprised if I did.
It's using Android 6.0.
