Samsung ended the Oreo beta program for the Galaxy S8 and S8+ in India and UK earlier this month, now the company has announced to its beta testers through 'Samsung Members app' that it is ending the beta program in the USA from yesterday, i.e January 26th.  Samsung had released the 7th and final Oreo beta firmware for the Galaxy S8 and the Galaxy S8+ last week. Since the company is ending its beta testing, we can expect the final roll out very soon. The announcement states that there will no further beta releases, no further responses to feedback. However, communication will still be open to beta users. Though Samsung says that it will make sure to roll out the update as soon as possible, it still didn't mention any time frame as of now. That said, it shouldn't take long, since the beta testing is now concluded, the next pit stop will the official stable release of the Oreo build. Samsung in the previous beta notice that it posted in the app two weeks ago mentioned that " we will do out best to distribute the official S/W version in January as soon as possible." Source
