The Samsung Galaxy M13 5G announced in July with Android 12 is receiving the One UI 5 update based on Android 13.
The update has firmware version M136BXXU2BVK3, and it comes with the November 2022 Android security patch in addition to the usual One UI 5 goodies.
Samsung is seeding the Android 13-based One UI 5 update for the Galaxy M13 5G in India right now, but the rollout should expand to other regions soon. You can also expect the Galaxy M13’s 4G variant to receive One UI 5 in a week or two.
If you live in India and haven’t received One UI 5 on your Galaxy M13 5G, you can check for it manually by navigating to your smartphone’s Settings > Software update menu.
