Users in Malaysia are reporting an OTA update is hitting their Samsung Galaxy A20s units carrying One UI 3.1 based on Android 11. And this marks the second and final major update for the Galaxy A20s that was released in 2019.
The firmware version is A207FXXU2CUFA and also bumps up the security patch to June 2021. All of the Android 11-intrinsic features are available along with some of the functionalities that One UI 3.1 brings. This includes a new UI design, better privacy control over apps, chat bubbles and overall better system optimization.
More markets should receive the update soon in the typical staged rollout. You might have to wait a couple of days before it hits your device too.
