Samsung's Android 10 rollout has been nothing short of spectacular. Not only did the company manage to deliver the update earlier than it promised, but the software is also largely bug-free, which usually isn't the case with a lot of major software builds. The Galaxy S10 series, Note 10 series and the Galaxy Note 9 are now running stable versions of Android 10 worldwide. Even the carrier-unlocked versions of the devices in the US have received the update alongside their carrier-locked peers, something that has never been the case for a long time.

Just yesterday, Samsung posted an updated Android 10 roadmap that put the Galaxy S9 series' Android 10 update in February. It was initially supposed to receive the software in January, according to the company's original schedule. Samsung has now released the update to some users; a full three days ahead of schedule. Furthermore, a US-based carrier Xfinity Mobile has beat everyone else too, as confirmed by a Reddit user.
