Realme has started rolling out incremental software update for Realme C25s which bring the June 2022 Security Patch carrying build number a of RMX3197_11.C.06, this is the first software update after the release of the stable version of Android 12.
Realme C25s was released in June ,2021 with Android 11 Realme UI 2.0 out-of-the-box.

Talking about the software update, we don't see any major improvements, unlike other devices that had Android 12, which used to get a lot of patch fixes in their first OTA update. But this device seems to have had a good software package we suppose and only brings the necessary security patch for June 2022.
Note that this is a staged rollout by Realme to ensure there are no critical bugs. It will be available to a few users and with the broader rollout, it will reach the rest of the users. If no critical bugs are found, the full rollout will be completed within a few days.
