Every Galaxy from the S23 series onward qualifies for Android 17, but for a group of 2023 phones and tablets it is the final big update.
Samsung's One UI 9, built on Android 17, is reaching every Galaxy from the S23 series onward. The S26, S25 and S24 families already have it, the S24 FE and A57 joined in October, and Galaxy A and M models roll out through November.
For a group of 2023 devices, this is the end of the line for new Android versions:
They will still get security patches into 2028, so there is no need to replace them yet. Newer AI tools such as My FanCam and Now Nudge skip the S23 line, though Privacy Alerts is included. To install, open Settings, tap Software update, then Download and install, on Wi-Fi with a charged battery.
One UI 9 eligible devices start with the Galaxy S23 series and include almost every Samsung phone, foldable and tablet released since. Samsung Japan put the cutoff in writing: support runs from the S23 series onward, and the Android 17 based update is already rolling out in stages, flagships first and Galaxy A and M models through November.
The catch is for 2023 buyers. If you own a Galaxy S23, S23 FE, Z Flip 5, Z Fold 5, a midrange A34 or A54, the M54 or a Galaxy Tab S9, One UI 9 is your final major Android upgrade. Your device keeps working and keeps getting security fixes into 2028, but no new Android version comes after this one. Here is the full picture, model by model, plus how to get the update today.
The safest way to read the list is by what Samsung has actually shipped or named, not by guesses. These are the models with a stable One UI 9 build or official confirmation in the reports we checked.
Some F and XCover models are eligible too, though Samsung has not published a model-by-model list for those lines.
The Galaxy Tab S9 series is on the same timetable as the S23 phones, so it gets One UI 9 as its final major Android upgrade.
The phones that stop here all launched in 2023 under Samsung’s older promise. In early 2022, Samsung pledged up to four generations of Android upgrades and up to five years of security patches on selected devices. The S23 shipped with Android 13 and One UI 5.1 in February 2023, so Android 14, 15, 16 and now 17 use up all four of its upgrades.
The models ending at One UI 9 are:
For the S23, a Samsung support representative reportedly confirmed back in August that One UI 9 is the final major upgrade. A known tipster later shared a similar reply about the S23 FE, saying updates to Android 18 had once been planned but the line now ends at Android 17.
Could a One UI 9.5 point release still sneak in? History says no. Samsung gave the Galaxy S22 One UI 8 last year, then halted its One UI 8.5 update even though both builds sat on Android 16. Samsung has made the same call before, and observers expect One UI 9.5 to debut on the Galaxy S27 instead.
Running out of Android upgrades is not the same as running out of support. The 2023 models above are expected to keep getting security patches until 2028, five years from launch, which matches Samsung’s 2022 policy. The S23 family still gets monthly patches, and the stable S23 One UI 9 build shipped with the October 2026 security update, which fixed 79 vulnerabilities.
Two things can shorten that in practice:
Missing features is mostly cosmetic. Missing patches is what puts banking apps and work email at risk. So 2028 is the realistic latest date to replace a 2023-era Galaxy, not 2026.
Every eligible model gets the core One UI 9 changes: a more flexible Quick Panel where you can rearrange controls and resize the brightness and volume sliders, upgrades to Samsung DeX and Samsung Notes, new accessibility options and an indicator that shows when apps are using your location. The A56 build also adds a Warranty and care menu with device diagnostics.
The newest Galaxy AI tools are a different story. My FanCam keeps a person you pick centered in a video, Now Nudge reads your screen to offer suggestions, Now Brief gets custom cards, and Call Brief summarizes calls. None of those four show up on the S23 series or S23 FE in compatibility tables, and in Korea, Samsung’s S23 Ultra release notes name only one new Galaxy AI item: scrolling back through live Interpreter conversations.
The S23 and S23 FE do get Privacy Alerts, which uses on-device AI to flag apps grabbing permissions in the background. The Galaxy A56 is not on Samsung’s Privacy Alerts list, and Samsung has not confirmed the newer AI features for it either.
Samsung delivers One UI 9 over the air. To check:
If nothing shows up, wait. Rollouts go country by country and carrier by carrier, and installing firmware meant for another model or region is a bad idea. In the US, early S24 reports pointed to carrier-locked phones getting the update before unlocked ones.
You do not need to rush into a new phone. An S23 or Z Fold 5 on One UI 9 gets a fresher interface, newer security patches and years of protection left. Just know it has reached the end of the feature road, so later One UI versions will pass it by.
A word of caution before you update: after the One UI 8.5 rollout in May, some S23 owners reported permanent green or pink lines appearing on their screens. You do not have to install One UI 9, but One UI is Samsung’s version of Android rather than an app, so it cannot be removed, and a third-party launcher only swaps the home screen and app drawer.
If you are shopping now, the gap is wide. Samsung moved to seven Android upgrades and seven years of security updates with the S24 in early 2024, and that promise did not apply backward to the S23. The Galaxy S26, which got One UI 9 in September, is supported until 2033.
No. Samsung Japan’s confirmation starts at the S23 series, and the S22 already had its One UI 8.5 update halted.
It is very unlikely. One UI 9 is the S23’s fourth and final Android upgrade, and Samsung skipped the matching point release for the S22.
The rollout is global and staged by country and carrier. One UI 9 also expands call Scam Detection to Canada, along with Japan and India.
