Samsung S9 series Pie Beta is tentatively expected to be released on 10-12-2018 (Monday).
Note 9 has been the reason why it was delayed in India (if you remember how Note 8 buyers were angry last year when it didn't get any Beta).
So far all Beta updates have been launched at the start of week so that they have adequate time within weekdays to fix any serious issues.
I would suggest members to avoid manually flashing Beta updates from other regions (UK/Germany). Updates meant for other regions might not have been tested well to work with carriers and bands in India. But if you still choose to manually flash, then make sure to do a complete backup using Samsung Smart Switch.
Let's hope we are not disappointed again on coming Monday 🙂😞
