One UI 9 delivers a common set of Galaxy AI tools, home‑screen and Settings changes, and system updates across the Galaxy S24, S25 and S26 lineups, while most meaningful differences affect cameras and a pair of notification features that the S24 does not receive.
One UI 9: shared Galaxy AI features and home‑screen changes
One UI 9 brings Call Brief, My FanCam, Now Nudge and custom Now Brief cards to the S24, S25 and S26 series. Call Brief can show contextual information during calls, such as a shared calendar event or local time for international numbers; the S24’s settings omit the Personal Data Intelligence explanation shown on the newer models, but the feature otherwise functions the same. My FanCam creates a cropped video that follows a selected person in an existing clip, including recordings made before the update. Now Nudge suggests actions based on on‑device context, and custom Now Brief cards let you choose up to three cards (weather, health or video information) and schedule when they appear.
Home‑screen options are also shared: you can keep a dedicated Google Search bar and a Samsung Finder bar at the bottom of the home screen (both optional and independently toggleable). All three generations gain Bixby home‑screen widgets that accept typed or spoken input; the updated Bixby can use Perplexity to provide web answers within its interface. Settings menus are cleaner across the board, with shorter menu entries for Galaxy AI features and the ability to open items for more detail.
Notifications: S24 misses Notification highlights
Notification highlights — comprising Summarize notifications and Prioritize notifications — are available on the S25 and S26 but remain absent from the S24 after the One UI 9 update. Summarize notifications provides short summaries of unread conversations to help catch up without opening every chat. Prioritize notifications moves important, time‑sensitive alerts toward the top of the notification panel. These two features can be enabled separately or together on supported phones. Separately, the FE models (S24 FE, S25 FE and S26 FE) do not support Call Brief, including the S26 FE that launched with One UI 9.
Camera differences by model
One UI 9 introduces several camera enhancements that vary by generation. The S25 series gains Super Steady with Horizontal Lock — a horizon‑leveling option not added to the S24, which retains regular Super Steady. The S26 already offered Horizontal Lock in the prior update. The S25 and S26 add a newer Dual Recording shortcut in Video mode with horizontal and vertical split layouts; the S24 continues to support Dual Recording through its existing mode but does not receive the new shortcut.
The S26 series is the only lineup to offer a 24MP option in standard Photo mode via Camera Assistant; this 24MP Photo mode was available on the S26 before One UI 9 and has not been added to the S24 or S25. The S24 and S25 still present 12MP, 50MP and 200MP options in the regular camera app, and they can shoot 24MP only through Expert RAW (or Expert RAW as a camera mode).
Night mode behavior differs on the S26: Auto, Max and Off Night mode controls appear directly in Photo mode on the S26 series, allowing Night usage changes without switching modes. The dedicated Night mode is hidden by default on the S26 but can be restored via Camera Assistant. The S24 and S25 retain the simpler Night shot on/off control in Photo mode plus a dedicated Night mode.
The S26 also expands Pro video frame‑rate options on Ultra models. For FHD and UHD (4K), the Galaxy S24 Ultra and S25 Ultra offer 120, 60, 30 and 24 fps; the Galaxy S26 Ultra adds 48, 100, 50 and 25 fps to that set (120, 60, 48, 30, 24, 100, 50, 25 fps). For 8K video, the S24 Ultra and S25 Ultra record at 30 and 24 fps, while the S26 Ultra supports 30, 24 and 25 fps.
Other system and service updates
Several platform features are common across all three generations. The Settings app gains a Warranty and care menu that consolidates warranty details and support options for the phone in use and other devices linked to the same Samsung account; it includes troubleshooting, diagnostics, repair requests and remote support. Under Settings > Connected devices, Driving Report can start recording driving information when the phone connects to a car via Bluetooth, then provide driving insights and weekly reports.
Samsung DeX receives updated desktop previews and easier switching between separate desktops, plus an option to automatically hide the status bar and taskbar. Device care adds a Block apps with excessive ads option that can put apps sending frequent advertising notifications into deep sleep; an intelligent blocking toggle analyzes notifications to help identify advertising alerts automatically. All three lineups also get Android 17’s Motion Assist, which places moving shapes on the screen to reduce motion sickness while traveling in a vehicle.
Overall, One UI 9 standardizes a number of Galaxy AI and system improvements across the S24, S25 and S26 families while leaving camera capabilities and two notification features as the main points of divergence.
