Besides these, there is a new Battery Protection section (limiting charging to 80%), Instant Slow-mo, and Circle to Search within Navigation Bar settings (to quickly search something on the screen using Google Assistant). Still, some features like Photo Ambient Wallpaper are exclusive to the Samsung Galaxy S24 series. Also, the changelog may differ between devices.
Before you proceed, ensure the device has more than 20% battery life. It is ideal to take a backup of the device before you update it. Also, ensure you have a stable internet connection to download the big update.
Step 1: Go to the Settings of the phone.
Step 2: Scroll to the bottom wherein you'll see the Software Update option. Tap it.
Step 3: Tap on Download and Install. It will check for the update and if available for your device in your region, it will show the One UI 6.1 build.
Step 4: Download and once it does, press Install. You can schedule it for a later time also.
It will take some time for the system to be updated. The device may reboot in the process.
Once it is updated and it boots to the lockscreen, unlock it and you'll be welcomed by One UI 6.1.
It will give you a small introduction to the One UI 6.1 features you get with this update. The highlight is Galaxy AI-based Advanced Intelligence features. The same has been listed above. To access these features, go to Settings > Advanced Features > Advanced Intelligence.
On the aforementioned page, you'll also get the option to process data (for AI processing) only on the device. This will be more secure but the online method is said to offer better results.
