Samsung has officially started developing One UI 7 for its highly anticipated Galaxy Z Fold7, marking the beginning of software testing for its next-generation foldable smartphone lineup. Just a day after a test software build surfaced for the rumored Galaxy Z Flip FE, a similar build has now been spotted for the Galaxy Z Fold7 on Samsung’s servers.
One UI 7 Development for Galaxy Z Fold7 Confirmed
A tipster on X (formerly Twitter) has uncovered the first test software build for the Galaxy Z Fold7, identified by the version F966USQU0AYB3 / F966UOYN0AYB3 / F966USQU0AYB3. The build appears to be associated with AT&T’s variant of the upcoming foldable, signaling that Samsung is deep into software optimization and testing ahead of the device’s official launch.
One UI 7.0.1 Instead of One UI 7.1?
According to early reports, Samsung may be working on One UI 7.0.1 for the Galaxy Z Fold7, rather than One UI 7.1. This speculation arises from rumors that Samsung has scrapped plans for One UI 7.1, as Google is expected to release Android 16 earlier than anticipated this year.
The early launch of Android 16 raises an interesting question:
➡ Will Samsung release the Galaxy Z Fold7, Galaxy Z Flip7, and Galaxy Z Flip FE with Android 15, even if they launch a month or two after Android 16?
Such a move could put Samsung in an awkward position, as launching a flagship foldable with an older OS version may not sit well with consumers. However, given Samsung’s recent approach to software update timelines, it remains to be seen how the company plans to navigate this situation.
Samsung’s Next-Gen Foldables: What to Expect
Samsung is expected to unveil the Galaxy Z Fold7 and Galaxy Z Flip7 later this year, alongside the Galaxy Z Flip FE, which is rumored to be the company’s first foldable “Fan Edition” device aimed at a more budget-friendly market.
With One UI 7 testing now underway, Samsung’s foldable lineup is shaping up to be one of the most anticipated releases of the year. However, all eyes will be on whether the new devices ship with Android 15 or if Samsung can fast-track Android 16 integration.
Stay tuned as more details on One UI 7 development and Samsung’s foldable strategy continue to emerge in the coming weeks.
