The rollout began with the latest and highest-end models , but within days it has extended to select foldable and mid-range phones, with a phased strategy that varies by country and carrier.
Samsung is rolling out the firmware in stages, and although Google released Android 16 earlier, the South Korean company is now accelerating the process and starting to close beta programs on some devices to activate the final version. At the same time, the number of builds and regions where the download is available are being confirmed .
Official deployment and update pace
The Galaxy S25 was the first to receive the update, and shortly after, it was rolled out to previous generations of foldable phones, with waves available to different markets that can take days or weeks to complete. This planning allows Samsung to react quickly to any potential issues.
Galaxy S24 devices have been found to have builds such as S921NKSU9CYI5, S921NOKR9CYI5, and S921NKSU9CYI3, a clear indication that the beta has ended and the stable rollout is now underway. According to reliable community sources, the updates are gradually being released outside of Korea.
The Galaxy S24 FE has begun rolling out updates in Europe and Iran with firmware versions S721BXXU7CYI5, S721BOXM7CYI5, and S721BOJM7CYI5, along with the September security patch . The update size exceeds 3 GB, typical of a major version upgrade.
Meanwhile, the Galaxy A56 5G debuted One UI 8/Android 16 in Korea with versions A566SKSU2BYI5, A566SSKC2BYI5 and A566SKSU2BYI5, and its arrival in more regions is ahead of schedule, with appearances in Europe and global rollout underway.

Highlights of One UI 8 with Android 16
One UI 8 introduces a more contextual , multimodal AI capable of suggesting actions, transcribing calls, translating in real time, and assisting with writing and drawing, in addition to features like Gemini Live for interacting with what's on screen without switching apps.

Multitasking gains flexibility with a 90:10 split screen , resizable pop-up windows, and improved task management. On foldable devices, the cover screen allows for more controls (music, notifications, and compatible apps) without opening the device.
In terms of security, Samsung strengthens Knox Matrix with automatic logouts in the face of threats, incorporates KEEP (encrypted environments per application) and deploys post-quantum encryption on public WiFi networks, along with clearer permissions and granular control.
Android 16 also brings a Live Updates pill in the top left corner for services like YouTube Music and Google Maps, and new customization options (clocks that adapt to the background , widgets, and visual settings). The availability of each feature may vary by model and region.
