Welcome to Vodafone Community
I've been waiting now for a while for the S8+ to get the new one UI update. I have seen on the internet that a lot of people have been receiving the updates however I have not received mine yet. it says on the Samsung members app that one UI for the S8 should have been rolled out in March. why is Vodafone not allowing the update to be pushed?
From what I understand some owners with Vodafone supplied phones have received the Samsung One Ui / Pie update @OliverLockie
It's sent out dependent on the phones build / serial number and in batches.
You could try seeing if the update is pending via Smart Switch option too.
Apart from that if the update isn't in your phones software update section then it's really a case of waiting for it to become available.
