Go to the play store and download the free version of Titanium backup or Rom Manager.
Titanium backup and Rom Manager both require ROOT access and they will ask you to allow it.
Forget about the "root checker" app, it's not needed and perhaps it's even faulty.
If Titanium backup or Rom Manager asks for root access and you grant it, it means that you are
fully rooted and you don't have any issues with root.
If trying the above does not show you that you do indeed have root access then download
cf-autoroot and unzip it and flash the TAR file using Odin.
CF-AutoRoot will give you full access after flashing it, but even then use Titanium backup
or Rom Manager to make sure you have root, not that "root checker" app you have.
Here is the direct download link for cf-autoroot:
This zip file contains cf-autoroot.tar and the Odin files in case you need it.
Unzip all the files into an empty folder on your desktop.
