Yesterday we found some information (which Samsung quickly removed) related to the rollout of Android 12 for Samsung phones in South Korea. The information detailed all the phones that will see the update, as well as the month in which Samsung expects to push it out.

Now we have similar information for the US in the Samsung Members app. However, Samsung has not pulled this info yet, so it looks like this is an official announcement that the company will be behind. As before, the calendar tells us which US based Samsung phones are getting One UI 4 based on Android 12 and the approximate time they are getting it.
Samsung says that this schedule may change at any time. As such, do not mark your calendars yet. However, it is reasonable to assume that your Samsung phone would see One UI 4 around the time that this calendar says it would.
