One UI Beta Program

Hello, i have contacted Samsung Support, but they redirected me to Developer Support, so I am writing here.

I’m very interested to participate in One UI 4 Beta Program (my device – G991U1), but it’s unavailable in my country (Uzbekistan). I already installed Beta 1 myself by downloading firmware zip (, but now i can’t find link for Beta 2. So I ask you please to register me in Program or provide link for Beta 2 zip file.

The only way I am aware of for Beta Testing One UI is from the Samsung Members app. If it isn’t in your country or available from your service provider maybe you can get it via a prepaid SIM card for a different country. But it is iffy since not all service providers are doing One UI beta testing.
