Samsung is expected to begin rolling out its One UI 7 update based on Android 15 from mid-April, according to GSMArena. The update will arrive to three generations of its smartphones over a period spanning from April to the end of May, starting with its more recent flagship models before extending to older devices.
GSMArena says the update schedule was sourced from a screenshot of a Samsung workshop, which was shared by a reader. The first batch of devices set to receive One UI 7 on April 18 includes the Galaxy S24 series, the Galaxy S24 FE, and the upcoming Galaxy Z Flip6 and Z Fold6. A week later, on April 25, the update will reach the Galaxy S23 series, the Galaxy Z Flip5 and Z Fold5, and the mid-range Galaxy A54.

Samsung will reportedly continue the rollout into May, with the Galaxy S23 FE receiving the update on May 16. This update cycle also includes the Galaxy S22 series, Galaxy Z Fold4, Z Flip4, and the mid-range Galaxy A53, A34, and A33. A final phase is scheduled for May 23, covering the older Galaxy S21 series along with the Galaxy Z Flip3 and Z Fold3.
The One UI 7 update is expected to introduce Android 15’s latest features while incorporating Samsung-specific enhancements, including the latest version of Galaxy AI. The interface is currently available together with the brand’s new Galaxy S25 series of smartphones that was launched last month.
