Tracking the samsung galaxy s26 one ui 9 release date galaxy s25 galaxy a Rollout
The latest updates regarding the samsung galaxy s26 one ui 9 release date galaxy s25 galaxy a cycle show that T-Mobile customers are the first in the US to receive the packages. Galaxy S26, S26+, and S26 Ultra users have confirmed an over-the-air package weighing approximately 4GB.

|---|---|---|---|
| Galaxy S26 / S26+ / S26 Ultra | Android 17 | Live on T-Mobile (Carrier First) | Approx. 4.0 GB |
| Galaxy S25 / S24 Series | Android 17 | Stable Builds Spotted on Servers | Pending Carrier Push |
| Galaxy Z Fold 7 / Z Flip 7 | Android 17 | Beta Concluding / Staging | Approx. 4.2 GB |
| Galaxy A57 / A56 / A36 Series | Android 17 | Firmware Validation Phase | TBD (Segmented Features) |
Despite previous shifts in internal deadlines, the public appearance of the 4GB update on production devices confirms that server bottlenecks have cleared.
