As of now Samsung hasn't officially said anything about Android 10. There aren't any confirmation from Samsung about any Android 10 beta program or when Android 10 is going to be released for Samsung devices. As from previous OS updates timelines and also from some reports, there might be an beta program soon for Newer Samsung Flagships devices. For Android pie or One UI updates, after newer devices S9 and Note 9 devices got the Pie update, few months later Samsung did release a beta program for unlocked s8 and Note 8. So Samsung may do the same thing this year too. But for now there is no any information from Samsung. So we'll just have to wait and see.
