Samsung has started internal testing of One UI 9 for the Galaxy S25 series, while also releasing beta updates for the Galaxy S26 lineup. The company's Android 17-based software is already being tested for the unannounced Galaxy S26 FE, with expectations that the first S25 beta will arrive in coming weeks.

Galaxy Z Fold8 and Galaxy Z Flip8 will debut with One UI 9 out of the box, with three folding smartphones expected to launch on July 22 in London. Samsung's software development continues to advance ahead of its flagship releases, maintaining the company's aggressive update schedule for premium devices.

The early testing phase indicates Samsung remains committed to delivering timely software updates for its flagship lineup, though consumers should note that the S25 series will likely receive One UI 9 after Samsung's folding devices hit the market.
