It’s worth making use of this stunning image quality by spending some time going through the wallpapers. Changing your wallpaper is extremely simple. Here’s a quick guide on one of the ways to do it.
Go into Settings
Tap on Wallpapers and themes
This will bring you to Samsung Themes. While it may seem crowded at first, this page is intuitive and easy to navigate.
Search Samsung Themes for the Best Wallpaper for You
The first option in the top row will take you to your gallery. You can select the images and videos you keep there.
Next, to the gallery link, you have the stock wallpaper options that come with your S9 or S9+. Most of these are abstract or galaxy-themed, and they all make use of the high resolution.
On the bottom half of your screen, you can scroll through the Featured wallpapers. Unlike the stock options, you have to use your internet connection to download these. You can look into the most popular wallpapers of the moment, as well as the newest options available online.
The bottom row lets you switch from browsing wallpapers to browsing themes. Every theme is customizable, and Galaxy encourages mixing and matching different wallpapers and themes.
So what happens after you tap on a wallpaper that you like?
Set as Wallpaper
When you select a wallpaper, you get to choose where it will appear. Your options are Home Screen, Lock Screen or Both.
As your Home Screen is crowded with icons, you might want to use a simple wallpaper. Your Lock Screen contains less information, so you can go for a more intricate wallpaper there. Some users like to use the same image for both screens.
Choose an option and you’ve got your new wallpaper set up.
Changing the Wallpaper from Your Gallery
There is another simple way to change your wallpaper. If you want to use one of the images or videos that you’ve made or downloaded, you can go through the gallery.
Select Gallery from your Home Screen
Here, you can go through your images and videos. You can use any video up to 100MB or 15 seconds as your wallpaper. But it’s possible to select longer videos, as long as you’re willing to crop them later.

Simply tap on the image or video you want to use.

Set as Wallpaper
Tap on the Set as wallpaper option.
Make Edits If Necessary
You can tap on Edit to alter your video or image. It may be necessary to crop it to size.
