Samsung took us by surprise yesterday by sharing the list of devices that will be receiving the Android 11 update, and then the same day launched the update for Galaxy S20 devices. Today, the update has extended to more regions as well. However, all of this was happening without any official confirmation from Samsung, so we thought that Samsung wants to keep things quiet.

However, the company has decided to go ahead and outline the official rollout plan for the Android 11 on the Galaxy devices and some other relevant information.
