Hi @sheeet. :robothappy:
There's an FAQ on the beta programme here: http://static.samsungmembers.com/betatest/binary/en/faq_sub.html#SECOND
The relevant bit from there about cancelling it:
"9. How can I quit Galaxy beta Programme?
You can cancel through “Withdraw from Galaxy Beta Programme” under the “Settings” menu in the “Samsung Members” app.
In order to use the official software and services, be sure to re-install (rollback) the final version of the official software.
You can re-install software by using the PC version of Smart Switch. Once the software is re-installed, the device will be reset and all data that was generated during the Galaxy Beta Programme will be erased.
(You can find details from FAQ #10 below.)
All data which had been backed up before installing the beta software can be recovered, but there may be limitations in recovering data that was created after installing the beta software.
The Samsung Service Center also supports re-installation of the official software.
Please contact the Call Center, and you will be guided to the nearest service center.

10. How can I restore the official software during Beta Programme?
You can re-install the official software by using the PC version of Smart Switch.
(You can download it from the following link - www.samsung.com/smartswitch).
Please connect your phone to your computer, launch Smart Switch on your computer, and press the “Update” button to re-install the official software (rollback)."
(This is for UK/Ireland phones, although one of the guides the UK & Ireland Mobile Tech team received has "the Deregister menu" instead of “Withdraw from Galaxy Beta Programme” in the above advice, so it may be worth checking for that term too.)
