The OTA update came with build number A107FXXU8CUG1 and the July security patch. The system has worked on autonomy, security, and performance. In addition, the developers have also added a proprietary One UI 3.1 Core-shell with an updated interface and new functions to the software.
By the way, this is the second and last major update for the public sector. As a reminder, it came out in 2019 with Android 9 Pie.
The firmware has been released so far for users in Malaysia and Vietnam. In the coming weeks, the update will reach other regions as well.
