Samsung is sending out its latest security update for the Galaxy S23 phones this July 2025. This update makes your Galaxy S23 more safe and works better, following similar updates for the newer S24 and S25 series.

This new update makes your Samsung Galaxy S23 more secure and work better. It improves things like your phone’s strong security (Knox), how it connects to your Galaxy Watch, your Samsung account, Wi-Fi, Bluetooth, and even the Emergency SOS feature.

The Samsung Galaxy S23 series, encompassing the S23, S23 Plus, and S23 Ultra, is now receiving the July 2025 security update. This update, weighing approximately 430MB, brings new One UI firmware builds: S911NKSS6DYG1 for the Galaxy S23, S916NKSS6DYG1 for the Galaxy S23 Plus, and S918NKSS6DYG1 for the Galaxy S23 Ultra.

This update is currently live for users in Korea, and the company will soon expand to more countries. It is an initial rollout, so it may take some hours or days to reach all models.

Right now, Galaxy S23 phones run on Android 15 with One UI 7. But good news! Users are really looking forward to the new features in the One UI 8 update. Samsung is expected to start sending out One UI 8 to older phones like the S23 series very soon.

Samsung recently released the stable One UI 8 update on its new foldable phones. While they haven’t announced a full rollout plan yet, the Galaxy S23 series is set to receive this big update soon.

To prepare your Galaxy S23 for the highly anticipated One UI 8 and other future improvements, install the latest security patch today. Simply navigate to Settings, then Software Update, and tap Download and install.

Good news for One UI users! Version 8.0 polishes existing features, notably live notifications. These handy alerts used to vanish quickly, but with the new update, they’ll finally stay put, offering a more reliable and less fleeting notification experience.

Get instant updates with live notifications! These handy alerts display real-time information from key apps (like countdowns, timers, and recorders) in multiple places. You’ll find them on your taskbar, within your main notifications panel, and conveniently on your lock screen through the “now bar” situated between the shortcut buttons at the bottom.

Its unique UI design enables users to expand the view and interact with the on-screen options, like closing the current timer or changing the playback.

The live notifications look great in their own panel, appearing as a list. However, there’s a catch: hitting the clear button makes them vanish along with everything else, except for one stubborn notification.

One UI 8

When you clear the notification, the app itself keeps running in the background. But here’s the catch: the live notification disappears. To get it back, you’ll need to open the app again (like your timer).

This issue, where only music notifications stay put, was seen on One UI 7.0 devices. It didn’t matter if you had the notifications panel set up in a different way; the situation was always the same.

New Version:

That problem really undermined what live notifications are for: keeping you in the loop on background activities. But One UI 8.0 has fixed it, ensuring your live notifications now stay put instead of disappearing when you need them most.

Now, when you clear your notifications, these live notifications stay right where they are, even as others disappear. It’s a small but significant improvement the developers included in the newest One UI.

Samsung still gives you control: you can easily swipe away most live notifications. The only exception is music notifications, which require you to close the music app completely from your background apps. If you want any live notification back, simply reopen its app.

Samsung is actively working to bring the big One UI 8 update to its older foldable phones, including the Z Flip 4 and Z Fold 4.

Samsung is now trying out its new One UI 8 software on the Galaxy Z Flip 4 and Galaxy Z Fold 4 phones from 2022. This shows that Samsung is actively working to bring its latest big update to its older devices.

A person who shares insider information (a “tipster”) has seen early test versions of the One UI 8 software for Samsung’s 2022 foldable phones, the Galaxy Z Flip 4 and Galaxy Z Fold 4.

These test versions have specific codes, like F936BXXUAIG3 and F721BXXUAIG3. These codes tell us that Samsung has officially started working on this big new update.

Samsung is currently testing the new One UI 8 update on its foldable phones in India (like the Galaxy Z Flip 4 and Z Fold 4). This means Indian users will likely get the update soon after it starts rolling out for older devices.

Samsung isn’t just updating foldables! One UI 8 is currently undergoing internal testing across a wide array of Galaxy phones, covering everything from mid-range models like the Galaxy A56 and A36, to top-tier devices such as the Galaxy S24 and S23 series, and even future releases like the Galaxy Z Flip 6 and Z Fold 6.

Samsung launched the stable One UI 8 update with the Galaxy Z Fold 7, the Galaxy Z Flip 7, and the Galaxy Z Flip 7 FE. However, Samsung is also testing new features on the Galaxy S25 series with a Beta update.
