In the United States, the Samsung Galaxy A13 5G, which was released in December with Android 11, is getting Android 12 with One UI 4.1.
The firmware version A136USQU2BVE9 is being rolled out to carrier-locked Galaxy A13 5G units. It includes the usual Android 12 and One UI 4.1 goodies, as well as an upgrade to Android security patch level May 2022 for the Galaxy A13 5G.
If you live in the United States and haven't yet received the Android 12 update on your carrier-locked Galaxy A13 5G, you can manually check for it by going to Settings > Software update on your phone.
