Summary: A glimpse of hope is that a UI 7 can come quickly for Galaxy S21, S22 and S23 users. It is based on a rollout schedule shared for China and Hong Kong. It is likely that this will not happen, however, not at least for global markets. This is very different from the initially mentioned.
There is a very minor opportunity that Samsung Galaxy S21, S22, and S23 series users will get a UI 7 quickly. A rolling plan for China and Hong Kong look fundamentally different for Korea and India.
There is a minor possibility that Galaxy S21, S22, and S23 users will get a UI 7 quickly
Based on the information shared within the Samsung members app, the Galaxy S21, S22 and S23 series users can get updates as soon as possible as this month. Needless to say, it does not look realistic, at least as far as global markets are concerned.
Here all devies Tha is mentioned for April 2025: Galaxy S24, S24 Plus, S24 Ultra, Galaxy S23, S23 Plus, S23 Ultra, Galaxy S22, S22 Plus, S22 Ultra, Galaxy S21, S21 Plus, S21 Plus, Galaxy S21 Alter, Galaxy S23 FE, Galaxy S23 Fe, Galaxy S23 6, Z Flip 5, Z Flip 4, Z Flip 3, Galaxy Z Fold 6, Z Fold 5, Z Fold 4, Z Fold 3, Galaxy Tab S10 Ultra, Tab S10 Plus, Galaxy Tab S9, Tab S9 Plus, and Tab S9 Altra.
For May 2025, these devices have been listed: Galaxy Tab S8, Tab S8 Plus, Tab S8 Ultra, Galaxy A55, A54, A53, A35, A34, A33, Galaxy M34, M34, M33, M33, Galaxy A25, A16, A15, A15, A15, A16, A14, A14, A14, A14, A14, A14, A14, A14, A14.

The original rollout plan is very different
The original plan shared in South Korea was spread till April, May and June. It was fundamentally different from it, as you can see. Users of the Galaxy S23 series were asked to receive updates in April. The Galaxy S22 and S21 series users were dropped down to May 2025.
The thing is that Samsung had to stop updates due to some insects. Before it recently closed again. So that Samsung's original rollout can be messed up with the schedule.
In any case, the update is coming soon. It is likely that this new roll out of China and Hong Kong will not be a new rollout. Well, not at least for global markets.
