I'm in UK still waiting.
If you want to you can download and sideload it:
I'm going to wait and try and grab one of the beta slots personally, but we have options at least.
The Beta for S10/Note 10 looks to be imminent for Uk, Android Police states customer representative gave a date of 21 October for the Note 10. They mention it will be available in China, France, India, Poland, Spain, and the UK "in the near future"
The lack of a "Coming Soon" banner in the UK Samsung Members app, would suggest to me that it won't be happening tomorrow or Monday here..
Maybe Samsung mods can comment further now?
