Realme has started the incremental rollout of the April 2022 security patch with A.35 build via OTA for Realme 9 Pro 5G model. The latest security patch brings the build number RMX3471_11.A.35 which carries Security, System, and Camera updates. This is probably a hotfix to a prior security patch with A.34 Build.
The update integrates the April 2022 Android security patch. It also fixed the rear camera mode which was earlier facing the problem of blurriness which has now been optimized in the new update. System performance has been enhanced and some of the previously known issues have been fixed.
Realme 9 Pro 5G was released on 16th February 2022, with Realme UI 3.0-based Android 12 out-of-the-box.
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 during 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.
Previously it had already received the April 2022 Security Patch, Realme 9 Pro: April 2022 Security Patch with A.34 Build and we have few doubts as the Changelog is the same as before, but there might be few internal fixes for the same update, the update was rolled out on 20th April 2022.
