Samsung's Android 17 update is spreading from its newest foldables down to the Galaxy S23 and budget A-series phones, but timing still depends on where you live.
Samsung's One UI 9 update, built on Android 17, is spreading beyond its newest phones. After debuting on the Galaxy Z Fold8 and Z Flip8 in July and reaching the S26 series in September, it's now landing on the Galaxy S24, Z Fold6 and Z Flip6, and it has started on the Galaxy S23 and several A-series phones in South Korea.
In the US, Galaxy S24 owners on AT&T and T-Mobile and unlocked Fold6 and Flip6 owners are getting it now. UK and Canadian dates haven't been published.
To check, go to Settings, then Software update. Expect a download of about 3.8GB on the S24, so use Wi-Fi and back up first.
One UI 9, Samsung’s Android 17 update, is now reaching phones that are two and even three years old, including the Galaxy S24 series in the US and the Galaxy S23 in South Korea. For S23 owners, it’s also the last big Android upgrade their phone will ever get.
If your Galaxy hasn’t shown a pop-up yet, you’re not alone. Samsung sends major updates in waves by country and carrier, so two people with the same phone can wait very different amounts of time. Here’s where things stand and what you get when it lands.
One UI 9 is out on a growing list of phones, though not in every country yet. It first appeared in July on the Galaxy Z Fold8, Z Fold8 Ultra and Z Flip8. The Galaxy S26 series followed in South Korea on Sept. 16, with the wider international release slipping to the end of September after Samsung pulled its original dates.
The 2024 flagships came next. The Galaxy S24, S24+ and S24 Ultra, along with the Z Fold6 and Z Flip6, started getting stable One UI 9 in South Korea, then in the US. Samsung also pushed it to the Galaxy S23, S23+, S23 Ultra, Z Fold5 and Z Flip5, and to mid-range models including the Galaxy A27, A37, A36 and A56, with the first builds landing in South Korea.
In the US, the update is landing on AT&T and T-Mobile versions of the Galaxy S24 lineup, plus unlocked Z Fold6 and Z Flip6 phones. That build comes with the Sept. 5, 2026 security patch.
For the Galaxy S23, Samsung hasn’t announced a worldwide schedule or confirmed US carrier timing. As of mid-October, the S23 rollout was limited to South Korea. Samsung also hasn’t published fixed dates for the UK or Canada, so owners there should expect the update to arrive in stages over the coming weeks.
The quick panel, the menu you pull down from the top of the screen, gets the most visible makeover. You can adjust brightness and volume sliders, resize the music widget and change how the panel looks.
Privacy gets real attention too:
There are smaller touches as well. Samsung Notes adds a tape tool to hide text, DeX (Samsung’s desktop mode) gets better window controls, and accessibility options include Text Spotlight for enlarging on-screen text and Mouse Keys. Galaxy S24 owners also pick up AI tools first seen on newer phones, such as My FanCam, which keeps one person framed in a video, and Call Brief, which shows the local time and country for international callers.
Not everything makes the jump. The Galaxy S24 misses out on notification highlights, scam detection and some AI features kept for the Galaxy S25 and S26. Some users have also reported occasional lag after updating, and Samsung is asking for feedback.
For the Galaxy S23, which launched with Android 13 in 2023, this is the fourth and final major Android version Samsung promised. Security updates continue into 2028. The Galaxy S22 and several older models are expected to miss Android 17 entirely.
Open Settings, tap Software update, then Download and install. If nothing shows up, your phone may simply not be in the current wave yet.
Plan for a big download. Galaxy S24 owners moving from One UI 8.5 are looking at about 3.8GB, and the Z Fold6 and Z Flip6 need about 3.5GB. Use Wi-Fi and back up your photos and files before you start.
One UI 9 is Samsung’s version of Android 17, with its own design and extra features on top.
It’s not expected to. The S22 series and several older models are set to miss Android 17.
Samsung releases it in waves by region and carrier, so an eligible phone can wait days or weeks.
