Ultimate One UI 5.1 Lock Screen Customization: Here’s how to renovate your Samsung Galaxy

One UI 5.1 is the king of lock screen customization when it comes to Android skins. Samsung brought pretty cool personalization options with the Android 13-based One UI 5 software, which is somehow derived from Apple’s iOS 16.
From a basic to an ultimate setup, Samsung One UI 5.1 enables users to create their dream lock screen. And you don’t need to spend much time in personalization, as lock screen renovation can be done on your Galaxy like playing games.
Here’s how to renovate the lock screen:
Samsung One UI 5.1 made lock screen customization as simple as adding a widget to the home screen. From the lock screen itself, you can access all of the ultimate recreation tools such as Wallpaper, clock, left/right shortcuts, emergency text, and notification style.
So, you only need to tap and hold on to the lock screen page, and make sure your Galaxy device is unlocked. In a millisecond delay, you will be able to see options like Wallpaper, along with outlined guidelines on elements you can adjust on the lock screen.
We are starting with the Wallpapers section. Tap the button, and the One UI will show you all the available wallpaper services, the same as the home screen. You can either pick a wallpaper from the native library or choose one from the listed services including Featured, Gallery, Graphical, Colors, Wallpaper services, or Downloaded.
After finalizing a new wallpaper for the lock screen, the clock style is the first element that we can renovate. There are five different designs including three digital and two analog. Besides, you can also remove the clock completely or expand the customization with Good Lock’s ClockFace plugin.
After tapping on your favorite clock style, you can adjust the size as per your preference. Once done, it becomes necessary to optimize the clock’s color with wallpaper from the available options including solid colors, gradient ones along with color spectrum.
Once finalized, it’s time to jump to the notification appearance, for which, Samsung brought two different designs. I prefer using the Icon only setting, as it keeps the lock screen clean, while you can either prevent notifications or choose the Details format.
It’s now possible to add emergency information on the lock screen, which someone can use to reach your family member. One UI 5.1 brings an option where you can put a phone number of instructions like allergy, which will be shown on the lock screen and visible to all without unlocking the phone.
Well, you can put any kind of text content in that field, which will show up on the lock screen as a signature. Just hit the contact information button, and write down your text content (either contact info or your name of fav text) along with emojis as I mentioned We ❤ Samsung.
Last but not least, the left and right swipe buttons can also be customized with different functions. There are two kinds of services including some that can be accessed without unlocking the phone and some that requires the phone to be unlocked. I’ve picked DND on Left and Camera on Right, you can pick yours!
