One UI 9.5: Samsung Is Testing the Update for Galaxy S25 Owners

There is good news for Galaxy S25 owners waiting for Samsung's next software update. One UI 9.5 is no longer being tested only for the upcoming Galaxy S26 series. New firmware builds have now appeared on Samsung's internal servers, suggesting that the company has already started work on the update for its previous flagship.

This is an important sign for anyone planning to keep their Galaxy S25 for another year. Samsung has not announced the beta program yet, but the latest leak suggests that owners may not have to wait too long to try the new software.

According to information shared by SamMobile's Fahad Ali Jawed, three internal firmware builds for the Galaxy S25 series have been spotted on Samsung's servers. Their version numbers are S938BXXUDEZKG, S938BOXMDEZKG and S348BXXUDEZKG.

These are not public update files, so nobody can install them yet. Still, their appearance shows that Samsung is moving ahead with development for its older flagship. Until now, the first signs of One UI 9.5 testing had mainly involved the Galaxy S26 series.

There is also an interesting detail about the bootloader. Earlier reports suggested that the Galaxy S26 could move to bootloader version 6 with One UI 9.5. The firmware numbers spotted for the Galaxy S25 do not point to the same change. This could mean Samsung will keep the current bootloader on older models, although we need more information before drawing a firm conclusion.

Samsung has not shared a date for the beta program. However, reports suggest that testing on the Galaxy S26 could begin as early as next week. If that happens, the Galaxy S25 might follow in the coming weeks, with early December looking like a possible window.

Of course, this is still based on leaks, not an official schedule. Samsung could change its plans, and the beta may not reach every country at the same time.

This is exactly the kind of news Galaxy S25 owners want to hear. Seeing Samsung test the next version on last year's flagship is a good sign for its software support. I would not rush to expect a beta next week, though. The important point is that development has started, and the S25 series appears to be part of Samsung's One UI 9.5 plans.
