So, in August Realme rolled out the Realme UI 2.0 update based on Android 11 with the August Security patch for beta-tester and now Realme has started rolling out the Reame UI 2.0 update with the September security patch to all the Realme C21 users.

The update carries the build number RMX3201_11_C.03 and brings some noticeable changes like three types of dark mode, UI customization, notification history, etc. The update carries the size of 180 MB ( for those who already running on Realme UI 2.0) and if you are someone who is getting the Realme UI 2.0 update for the first time on your Realme C21 then for you the size will be around 3 GB.
