Well, it has been announced that Samsung is going to release it this week, most probably this Thursday. However, recent tweets also say that India is among the second wave of countries that will get the update on May 26th (that full week, most probably that week's Thursday).
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 S26 series. Please stay active on the Samsung Members application, as you will be notified when it becomes available for your device.
