If you have you downloaded and deleted a lot of apps on an Android phone, you probably have a lot of home screens that you can scroll between. Moving the apps from one to another to clean up the mess is pretty straightforward. Just push, hold and drag like on Iphone. But that might lead you to a lot of unnecessary emtpy pages that is especially anoying on Android since the screens are in an infinite cycle. Here is how to get rid of those extra emtpy screens.
1. Go to the blank screen and hit the menu button (left underneath the screen)
2. Choose Edit page and all the screens you have will pop up.
3. Drag the emty screen to Delete.
This procedure at least works on a Samsung Galaxy Note II with Android 4.1.2
