Looks like they may have a long wait for the S21's official Android 12 to be released in India if this GSMArena article is correct... 21 December is designated for the roll-out there!

At long last, (8 days), the last U.K. carrier branded phone update is now rolling out.

Three network users on their carrier branded devices for CSC code H3G are receiving the Android 12, One UI 4 update, BUK8.

Only 10 days after beginning, Samsung has virtually completed the roll-out of Android 12, One UI 4, to over 100+ of their global branded and unbranded Exynos devices for Europe, Asia, Africa and the Nordic and Baltic regions.

It is now the turn of South America to receive Android 12 beginning with its release to the Chilean non-carrier branded devices on CSC code, CHO.

No news I'm afraid on when Australia and New Zealand will be updated yet but it shouldn't be too long.
