Samsung didn’t announce One UI 8 Stable Update release date at Unpacked; the rumored timeline is untrue

On July 9, Samsung held its Unpacked event, where it unveiled new foldable phones and smartwatches. Samsung also introduced Android 16-based One UI 8 but didn’t reveal the Stable Update release date for Galaxy devices. Recently, plenty of rumors backed by Support Chat screenshots spread online, claiming release dates that are untrue.
Galaxy Z Fold 7, Z Flip 7, and the Z Flip7 FE come preinstalled with Android 16. Samsung is running the One UI 8 Beta Program to optimize the update for the Galaxy S25 series; the sooner the testing completes, the sooner the Stable release date will approach. For now, there is NO OFFICIAL RELEASE DATE FOR ONE UI 8 UPDATE.
While Samsung didn’t reveal a release date, it did mention in its press release that the new OS upgrade “is expected to commence with the Galaxy Z Flip7 and Fold 7.” This statement is about One UI 8’s market debut with new foldables around July 25.
Regarding existing devices, Samsung officially announced that the update “is expected to gradually rollout to other Galaxy devices.” That said, the update’s coming gradually to older phones but there’s no release date specified by Samsung.
Statements from Samsung’s support staff can’t always be considered official statements. The support staff’s main purpose is to assist consumers with their purchases, product information, feedback, queries, and concerns, not the software part.
If you come across such stuff that the One UI 8 update drops mid-July, take it as a rumor material. The Beta testing is still underway, and Samsung is making improvements across the OS to ensure a bug-free software is shipped to the consumers.
One UI 8 amplifies the features and user experience introduced in One UI 7. Minor tweaks across the user interface, redesigned stock apps, enhanced connected ecosystem UX, and expanded Galaxy AI features make it worth the wait.

Google’s partnership brings early One UI 8: Will your Samsung get Android 16?

Samsung officially launched One UI 8 with Android 16 on July 9, 2025, at its Galaxy Unpacked event. This is way earlier than the usual timeline. Samsung typically releases major updates in the fall, but this time it’s giving us a summer surprise.
Thanks to a closer partnership with Google, we have an early release of One UI 8. With this collaboration, Samsung becomes the first company to launch a new device with Android 16 right out of the box. Samsung’s latest Galaxy Z Fold7 and Flip7 are shipping with One UI 8 pre-installed.
Before going into supported devices, let’s find out the key features:

Important Note: The regular Galaxy S21 series (S21, S21+, S21 Ultra) won’t get One UI 8 because these devices have reached the update limit. The S21 series came with Android 11 and has already received its four major updates.

When will your phone get the update?
Already Available:
The Galaxy S25 series has been testing the beta version since May 28, 2025, and should get the stable One UI 8 version by late July or early August 2025.
- August 2025: Galaxy S24, S23, and older foldable phones

Samsung’s software rollout happens in phases. The company starts with its newest flagship phones and gradually moves to older models.
One UI 8 with Android 16 is a solid update that makes your Samsung phone smarter, faster, and more secure. If you have a Samsung phone from the last 2-3 years, you will probably get this update before the end of 2025. The exact timing depends on your specific model and where you live, but Samsung is moving much faster this time compared to previous updates.

2 useful features that will make Samsung users eager for One UI 8

Now Bar and Now Brief are the most useful features in One UI 7 that continue to remain in One UI 8 headlines. In One UI 8, Now Bar and Now Brief are the two most useful features for which Samsung users should be pretty excited.
1. Now Brief
Samsung introduced Now Brief in One UI 7, but the availability is limited to the Galaxy S25 series. Meanwhile, the One UI 8 update is all set to enable this AI-powered feature on even more Galaxy devices, including the Galaxy S24 series.
One UI 8 not just expands Now Brief to more devices. Recent developments suggest that the function is getting even more AI love. Based on data from Contacts, Now Brief will present AI-made Birthday greetings in a shareable format.

2. Live Updates on Now Bar
Samsung’s Android 15 skin debuted Now Bar, which showcases live updates right on the lock screen. Google integrated a similar functionality in Android 16 version that’s called Live Updates and available on Pixel smartphones.
Android 16’s Live Updates are integrating with Samsung’s Now Bar in One UI 8. Google confirmed food-delivery alerts are coming to Now Bar as live alerts. The company is also working with third-party app developers to optimize real-time alerts.
That said, Now Bar is all set to unlock its full potential in One UI 8. Gradually, for sure, Samsung and Google will elevate live alerts. As new partners join, the Now Bar pill will present real-time alerts right on your Galaxy’s lock screen.
Another upgrade to the notification system that will be added in One UI 8 is force-grouping notifications. Android 16 intends to forcibly group notifications to reduce overload; you will be able to access the group with a tap
Now Brief and Now Bar are just two features that are enough to make One UI 8 a big upgrade. These enhancements are enough to make you eager for the next big upgrade, but there’s still plenty more to explore for your Galaxy.
