Samsung has updated its Android 10 roadmap in many countries to say that the Galaxy S9 and Galaxy S9+ are now slated to get the update in February. In some markets, like the Netherlands, the roadmap — which can be found in the Notices section of the Samsung Members app — still says the update will be released in January. That most likely won't happen, as only a few days are left before we enter February and even beta users haven't received the stable Android 10 update yet.
Samsung has been pretty quiet about its progress on the Android 10 update for the Galaxy S9 and Galaxy S9+. But that's standard fare for the Korean giant. It never really communicates to consumers why a certain update might be taking too long to come out and simply releases the update once it's ready. The One UI 2.0 beta program for the Galaxy S9 and S9+ has been ongoing for two months at this point, and even Samsung's beta team hasn't revealed why it is taking so long to finish work on the update.
Considering the Galaxy Note 9 has already received Android 10 in many countries, we can only imagine there must be some serious issues that are delaying the update's release for the Galaxy S9 and S9+, which have mostly the same hardware and software as the Galaxy Note 9. Whatever the reasons may be, all Galaxy S9 owners can do is wait and hope that Samsung brings Android 10 and One UI 2.0 to their phone as soon as possible.
