Only for S26 series right now. S25 might get it in next 3 months if you go by previous schedules for betas. S24 would take at least 4-5 months before it could get one UI 9 beta.
As per your query, we would like to inform you that as for now there is no official information available about UI 9 beta update for S24 series. Please stay active on the Samsung Members application, as you will be notified when it becomes available for your device.
