How to Change the Background on Your Samsung Device
Personalizing your Samsung phone or tablet starts with the wallpaper — and Samsung's One UI makes it surprisingly flexible. Whether you want a live photo on your lock screen, a solid color on your home screen, or a dynamic wallpaper that shifts throughout the day, the options go well beyond what most people realize. Here's a clear breakdown of how it works, what affects your experience, and what to think about before you choose.
What "Background" Actually Means on a Samsung Device
On Samsung devices running One UI, the term "background" covers three distinct surfaces:
- Home screen wallpaper — the image or color behind your app icons
- Lock screen wallpaper — what appears when your phone is locked
- Always On Display (AOD) — a low-power persistent screen available on supported Galaxy models
You can set the same image across all three, or mix and match. That flexibility is one of the more useful features in One UI, and it's worth knowing upfront that these are separate settings — not one global toggle.
How to Change Your Wallpaper on Samsung: The Basic Steps
The most direct path works on most Samsung Galaxy phones and tablets running One UI 4 and later:
- Long-press an empty area on your home screen
- Tap Wallpaper and style
- Choose My wallpapers, Gallery, or a live/dynamic option
- Select your image or style
- Choose whether to apply it to the Home screen, Lock screen, or Both
- Tap Set
Alternatively, go to Settings → Wallpaper and style — same destination, different route. This path is often more reliable if your home screen is crowded with widgets or icons that make long-pressing difficult.
For the lock screen specifically, you can also long-press the lock screen itself when the phone is locked (on some One UI versions) and tap Customize to edit the clock style, widgets, and wallpaper together.
Wallpaper Types Available on Samsung 🖼️
| Type | What It Is | Notes |
|---|---|---|
| Static image | A single photo or graphic | Works on all Galaxy devices |
| Live wallpaper | Animated or interactive backgrounds | May drain battery faster |
| Dynamic / Color palette | Changes based on time of day or system theme | One UI 5+ feature |
| Shuffle | Rotates through a photo album | Available on newer One UI builds |
| Solid color | Plain background from a color picker | Useful for battery and focus |
Dynamic wallpapers and color palette themes are tied to One UI version and device generation — not every Samsung device supports them equally. Flagship Galaxy S and Z series phones generally have fuller support for these features than budget A-series models.
How One UI Version Affects Your Options
Samsung's software layer, One UI, is the variable that determines which wallpaper features are available to you. Here's how the generations generally break down:
- One UI 3.x — Standard static and live wallpaper support, limited customization
- One UI 4.x — Added color palette theming derived from your wallpaper (Material You-style)
- One UI 5.x and 6.x — Expanded lock screen customization, shuffle wallpaper, improved AOD integration, and more granular control over home and lock screen independently
To check your version: Settings → About phone → Software information → One UI version
If your device is on an older build, some steps described online may look different or not appear at all. Samsung's update schedule also varies by device tier and region, so two Galaxy A-series users might be on different One UI versions depending on when they bought their phones and where.
Using Your Own Photos as a Wallpaper
Setting a photo from your Gallery is straightforward — select Gallery from the wallpaper picker, choose your image, then use the crop/zoom tool to frame it exactly how you want it.
A few things that affect the result:
- Image resolution: Higher-resolution photos look sharper, especially on QHD+ displays found on premium Galaxy models. Low-resolution images can appear blurry or pixelated when stretched to fill the screen.
- Aspect ratio: Samsung's wallpaper tool will crop your image to fit the screen. If you want specific framing, crop the photo manually in the Gallery editor before setting it as wallpaper.
- Scrolling parallax effect: One UI applies a subtle parallax effect (image shifts slightly as you swipe between home screen panels) by default. You can disable this in the wallpaper settings if you prefer a static frame.
Changing the Background on Samsung Tablets
The process on Galaxy Tab devices mirrors the phone experience, but the larger canvas introduces a few extra considerations. Samsung's DeX mode (available on select tablets) has its own desktop-style wallpaper that can be set separately. If you use your tablet in both touch and DeX modes, you may want different wallpapers for each — and that's supported.
Multi-panel home screens on tablets also mean the parallax effect is more noticeable. Some users prefer to disable it on larger screens for a cleaner look.
Third-Party Wallpaper Apps and Samsung
Samsung's Galaxy Themes app (pre-installed on most devices) offers wallpapers alongside full theme packages. These can change your icons, color scheme, and wallpaper simultaneously — useful if you want a cohesive look without manually matching elements. 🎨
Third-party live wallpaper apps from the Google Play Store also work on Samsung devices, since One UI runs on Android. These show up under the Live wallpapers section of the wallpaper picker once installed. Performance and battery impact vary depending on how animation-intensive the wallpaper is and which Galaxy model you're using.
The Part That Depends on Your Setup
The steps above cover the mechanics reliably — but what works best for any individual user depends on factors that vary: which Galaxy model you own, which version of One UI it's running, whether your device has received the latest regional update, and how you actually use your home and lock screens day to day.
Someone who uses their phone's AOD constantly has different tradeoffs around live wallpapers than someone who keeps AOD off. A user on a budget Galaxy A-series will see a different set of options than someone on a current Galaxy S or Z series. And whether the dynamic color palette feature is useful or distracting comes down entirely to personal preference.
The settings are there — how you configure them is the part only your own screen can answer.
