Samsung has been rolling out One UI 9 in stages across its flagship lineup, with the Galaxy S26 series getting first dibs before the rollout widened beyond Korea. Now, Samsung is opening the door to more of its 2025 flagships, as stable Android 17 is reaching the Galaxy S25 series, Galaxy Z Fold 7, and Galaxy Z Flip 7 in Korea.
For the Galaxy S25, S25 Plus, and S25 Ultra, the stable release is arriving with firmware version S93xNKSUCDZIF. According to screenshots shared by leaker Tarun Vats on X, beta testers are seeing a download of roughly 535MB, while users coming straight from Android 16 and One UI 8.5 are getting a much larger package. A Galaxy S25 Ultra screenshot we’ve seen shows the same stable build weighing 3,851.56MB.
