The official release of One UI 7 will begin in Q1 2025 with the next-generation Galaxy S series devices. Over time, it will expand to other Galaxy devices, reflecting Samsung’s commitment to extended OS upgrades.
Samsung seems to have revised its smartphone production target for 2025. Meanwhile, Samsung is aiming to foster Galaxy S25 series production than the S24 series. New input suggests that the production target is reduced by 7 to 8 million.
According to TheElec, Samsung is cutting smartphone production estimates for 2025, but the flagship Galaxy S25 series could be produced higher than the Galaxy S24 series.
Back in October, it was reported that Samsung is aiming to produce 237 million phones in 2025. As per the revised plan, the company has set a production target of 229.4 million.
In particular, the Galaxy S25 series is expected to be produced at 37 million units. Meanwhile, the Galaxy S24 series is estimated to be shipped 35 million units this year.
It seems the budget and entry-level phones would be produced in slightly lesser quantities. The aim is to maintain a conservative outlook without impacting premium sales.

- Galaxy Z Flip 7 – 3 million
- Galaxy Z Flip FE – 900,000
- Galaxy Z Fold 7 – 2 million
These figures sum up to a production target of around 6 million units. Combining a Fan Edition model, the sale is still estimated at 6 million – suggesting a slow pace of adoption.
The Galaxy S25 series will launch in late January next year, while the foldable devices may debut in July. Samsung is also preparing to introduce a Slim variant of the S25 series, while the launch timeline is uncertain.
