We've been tracking Samsung's One UI 8 and Android 16 updates though the beta programme. Last week we reported that Samsung had confirmed late September for updates, but thanks to a leak, we have a slightly more detailed look at things.

It seems that the Galaxy S25 models will start receiving One UI 8 from 18 September, the S24 models from 25 September, and S23 from 2 October. The details come from an online leak, shared via X and organised by 9to5Google.

The original leak appears to be for Turkey and there could be some regional differences. In the past, we've seen that sometimes not all models get the update on the same day, but over the next month we should see One UI 8 and Android 16 land on a full selection of recent Samsung devices.

Through this process, the Galaxy S is the main focus, but generally speaking, the more recent your device, the sooner you'll get the update. The exception appears to be the Galaxy Z Flip and Z Fold 6, which isn't due until 2 October.

Galaxy Watch models will also get the update through October and November.

Here's a breakdown of when you might expect to get the update for Samsung's best phones, with more devices on the source:

What does One UI 8 bring to Samsung devices?

While Android 16 didn't bring a huge number of user-facing features, the biggest benefit for Pixel users was the Material 3 Expressive design. For Samsung, however, One UI 8 is a chance to bring in a whole range of features for its users.

That includes more Galaxy AI tools, meaning that the experience on the Galaxy Z Fold 7, for example, will be reflected on the Galaxy S25 and older devices. That includes wider access to Audio Eraser and a more advanced Now Brief.

There are new calling features, a more advanced Quick Share experience and navigational improvements through things like the Quick Settings. There will be tweaks in a lot of Samsung's own apps, too.

How to check if your phone has an update available

In most cases, you'll get a notification appear on screen when an update is available. Tapping this will go through to the updates section of the menu so you can find the details. Otherwise, head into Settings > Software update and you'll be able to manually check if there is an update for you.
