I have just found out how to create folders for the Home Screen and rearrange app icons on the Home Screen.
I was searching videos on YouTube and came across video tutorials for the S5 which helped me, to create folders you go to the apps screen then hold down an icon and drag it to the top left where 'create folder' should be and let go, then a folder will appear which you can name and after you save it the folder appears on the Home Screen, before you save you can also press on a + symbolto add more apps to the new folder.
To rearrange icons I don't know how I missed this, press the Home button to make sure you are on the Home Screen, then down the bottom right corner next to the Apps icon there is a pencil icon for Edit Page from here you can move app icons around and into existing folders.
I contacted Samsung live chat twice about this issue and they did not know how to resolve it and I was about to take my Tabs S back for a replacement!
Thanks for the replies to my post it is appreciated.
