I want to get Beta Updates. So i signup here http://static.samsungmembers.com/betatest/binary/nos/US/faq_sub.html with my Samsung account. But i can't find Samsung Beta Program App and Samsung Members App in play store. So i downloaded apk and install. But i am having service error in both apps. I am not sure my device and region are eligible for Beta Program. Or am i missing something? Is there any other way to get Beta Updates?
