I'm trying to install the One UI Beta on my Samsung S9 but when I tap "Register" I get an error "Your phone model isn't supported.(4021)". Is someone else having a similar issue? - I'm in the UK - My phone is a Samsung Galaxy S9 - Phone is unlocked - I'm connected to Wi-fi - I have enough storage (64GB left) - Latest firmware/software updates installed - Samsung Members app is up to date I contacted Samsung Support and they said I should be elegible. I have no idea why it doesn't work!
