Samsung One UI 8 Launches August 14: Full Galaxy AI Experience Hits S24 Series First
From early betas to feature highlights, here’s everything we know so far about One UI 8
I remember seeing a prototype of One UI 3 on a Galaxy S20+ in a closed-door session back in 2020. At the time, Samsung’s UX team whispered excitedly about "focus mode tiles" and a new "visual language for bigger screens." It felt ahead of its time then.
Four years later, One UI 8 has finally realized that vision - except now it’s AI-powered, seamless, and frankly, a little mind-blowing.
The biggest story in One UI 8 is not what’s visible at first glance. There’s no wild redesign or flashy launcher overhaul. Instead, it’s what’s happening under the hood.
Samsung has added a new “Galaxy AI Custom Engine” that learns from your daily behavior. Over a week of use, it begins adjusting your widget stack, quick settings, and even system haptics based on usage patterns.
“You don’t just control the phone. It starts to anticipate you,” said Mina Lee, Senior UX Architect at Samsung Mobile. “We focused on calm intelligence, not flashy AI.”
For example, open your camera during golden hour and One UI 8 will nudge your Gallery into “Sunset Mode,” auto-sorting relevant images into a temporary folder and preloading editing presets you often use on similar shots.
AI also enables dynamic context-aware Quick Panels - for instance, if you connect to a smart TV, your notification shade swaps in media and screen casting tools by default.
One UI 8 now supports Live Lock Screens, similar to iOS Live Activities - but more customizable.
You can pin apps like Spotify, Google Fit, or Samsung Health right onto the lock screen in interactive widgets. These update in real time and even support gesture-based input (like double-tapping to pause music or swiping to dismiss).
Reddit users have already started testing it on the beta:
u/PixelPuncher87: “It’s like Live Activities from iOS but way less locked down. I’ve got a countdown timer, music widget, and sleep tracker all layered. Feels like my phone knows me now.”
Multitasking Is Smarter - and More Invisible
Split-screen multitasking hasn’t changed in layout, but its brain has evolved. One UI 8 introduces “Auto-Stack”, which remembers your most-used app pairs and intelligently suggests layouts based on time and context.

Say you always open Chrome and Samsung Notes around 9 a.m.? One UI 8 now prompts you with a one-tap suggestion as you unlock your phone.
“We wanted to reduce friction in muscle memory,” explained Joon Park, Head of UX Innovation at Samsung’s Seoul lab. “The idea is to get you where you want to go without asking.”
One UI 3 (2020): Cleaned up navigation, introduced major visual spacing.
One UI 4: Better Material You integration, privacy toggles.
One UI 5: Stackable widgets and animation overhaul.
One UI 6: Smarter photo editing, Studio video editor.
One UI 7: Introduced Circle to Search and Galaxy AI beta.
One UI 8 feels like the spiritual culmination of all these versions: clean, responsive, and, crucially, aware.

The full rollout begins August 14, 2025, alongside the expected Galaxy Z Fold 7 and Galaxy Z Flip 7.
If you’re on a Galaxy S24, Z Fold 6, or Tab S9 Ultra, expect the update to land via OTA in the first wave. Budget phones like A55 and M15 will follow in late September.
Samsung has also added AI-powered migration tools - so if you’re upgrading, your home screen layout, habits, and lock screen widgets come along too.
u/OneUIObssessed: “Just installed Beta 2 on my S24 Ultra. I swear the keyboard latency is even lower. Also, AI suggested I add a flashlight tile when it saw I use it every night at 11 PM. Creepy - but useful.”
