A report by XDA Developers cites certain forum members to say that Samsung is now letting unlocked Galaxy Note 9 users in the US sign up for the One UI beta. This is apparently showing up when you download the latest Samsung+ APK (version 18.104.22.168 beta). Apart from unlocked units, Galaxy Note 9 users on Sprint and Verizon networks are also getting the sign-up page.
