Samsung has launched its new Z Fold and Z Flip devices with One UI 8, just a month after the public release of Android 16, thanks to the adoption of Google's "Trunk Stable" development model. This model allows all development to occur within a single, stable internal branch, facilitating faster feature integration and reducing merge conflicts. Android 16 debuted in June, marking a quicker release schedule compared to previous versions. Samsung has confirmed its adoption of this model for One UI development, operating from a single development branch and collaborating with Google to refine the approach. This shift has enabled Samsung to expedite the rollout of One UI 8, aligning its release schedule with Google's updates.
