Yeah, I have side loaded the image already but it broke Google pay for some reason and I'd rather have the updates automatically rather then messing about each update. I've gone back to stock.
That's the way it has happened over the last few years - Hemant and other users of Europe get beta 1 and it launches here with beta 2. Hopefully it will launch soon. Time to switch to Samsung Pay for contactless payments for a few weeks instead of Google Wallet!
