But now, Samsung has finally released (via SamMobile) the long-awaited Android 11 based One UI 3.1 update for the Galaxy A21 smartphone users in the US. The update comes with the firmware version number A215USQU5BUI4.
Along with these major changes, the update also brings the September 2021 security update which optimizes the system security and enhances the phone’s performance.
One of the most significant changes introduced by Android 11 and One UI 3.1 is the updated user interface.
