Your Samsung S23 Ultra Can Transform Any Photo Instantly
You just captured the perfect portrait, but the cluttered room behind your subject ruins the shot. Or maybe you want to place a family member in front of a famous landmark they’ve never visited. With the Samsung S23 Ultra, you’re holding one of the most powerful photo-editing tools in your pocket, capable of performing what once required expensive desktop software.
Changing a photo’s background is no longer a complex task for graphic designers. Whether you want a clean, professional look for a LinkedIn profile, a fun, creative image for social media, or simply to fix a distracting backdrop, your phone has you covered. This guide walks you through every method, from the simplest one-tap option to the most detailed manual control.
Understanding the Tools at Your Disposal
Before diving into the steps, it helps to know what you’re working with. The Samsung S23 Ultra comes with a powerful suite of editing tools primarily housed in two places: the Samsung Gallery app and the Expert RAW app for more advanced users. The magic for background removal and replacement happens through a combination of AI object recognition and layered editing.
The phone’s processor is designed to quickly separate subjects from backgrounds, a process called segmentation. This allows you to delete the original background, blur it, or replace it with a solid color, a gradient, or a completely new image. The key is starting with a photo where your main subject has clear edges, which makes the AI’s job much easier.
Method 1: The Quickest Path with Gallery’s Object Eraser
For removing unwanted elements or people from your background (rather than replacing the whole thing), the Object Eraser is your fastest tool. It’s perfect for cleaning up a messy park scene or deleting a photobomber.
Open the photo in your Samsung Gallery app.
Tap on the pencil icon at the bottom to enter the editor.
Look for the “Labs” or “More” options in the bottom toolbar and select “Object Eraser.”
Circle or lasso the object in the background you want to remove. The AI will analyze the surrounding area and fill it in seamlessly.
Tap “Erase.” You can undo and re-try if the result isn’t perfect.
Save a copy of your edited photo.
This method is ideal for spot-cleaning. The AI does a remarkable job of reconstructing the background based on the pixels around the erased object. For a complete background replacement, you’ll want to use the next method.
Method 2: Complete Background Replacement Using “Remaster” and Layers
This is the most powerful native method for a full swap. It uses the AI remaster feature combined with layer editing to place your subject onto a new canvas.
Open your desired photo in the Samsung Gallery app.
Tap the three vertical dots in the bottom right corner or the “More” option.
Select “Remaster photo.” The AI will instantly enhance the image and, crucially, it identifies and separates the main subject.
Once remastered, tap the pencil icon to enter the full editor.
Look for the “Layer” or “Add” icon (often looks like a square with a plus). This lets you add a new image layer.
Choose the new background image you want to use from your gallery. It will be placed behind your subject.
Use the resize and position tools to adjust the new background to fit.
You may need to use the “Cut” or “Selection” tool to fine-tune the edges of your subject if the AI’s initial separation wasn’t perfect. Zoom in for precision.
Once satisfied, save the composite image as a new file.
The success of this method hinges on the initial “Remaster” step cleanly picking out your subject. It works best with high-contrast photos where the subject stands out clearly from the original background.
Method 3: Using Third-Party Apps for Specialized Effects
While Samsung’s native tools are robust, dedicated apps offer more templates, advanced edge refinement, and creative backgrounds. Two excellent free options are Adobe Express and PicsArt.
For a streamlined experience with professional templates, try Adobe Express.
Download Adobe Express from the Galaxy Store or Google Play Store.
Open the app and tap the “+” button to create a new project.
Choose “Edit a photo” and select your portrait from the S23 Ultra’s gallery.
Tap the “Background” tool in the bottom menu. You can choose “Remove” for a transparent background or “Replace” to select from solid colors, gradients, or uploaded images.
The app provides a simple slider to refine the selection edges, which is great for tricky areas like hair.
Add text or graphics if desired, then export your final image.
For more artistic and social-media-focused backgrounds, PicsArt is a powerhouse.
Install PicsArt and tap the purple “+” button to start.
Select your photo, then tap “Cutout” from the tools at the bottom.
Use the automatic AI selection or the manual brush to outline your subject precisely.
Once the subject is cut out, tap “Next” and then “Background.”
Browse a massive library of free backgrounds, from abstract patterns to scenic landscapes. You can also use your own.
Position your subject and use the edge blur tool to make the composite look more natural.
Save and share your creation directly from the app.
Troubleshooting Common Background Editing Issues
Even with great AI, you might run into problems. Here’s how to solve the most frequent ones.
If the AI isn’t cleanly separating your subject, especially around hair or fuzzy edges, the original photo might be the issue. Go back to the editor and use the manual selection or brush tool to add to or subtract from the AI’s selection. Zooming to 200% can help with this precision work.
A common giveaway of a replaced background is lighting mismatch. Your subject is lit from the left, but the new background’s light source is on the right. To fix this, use the editing tools to adjust the brightness, contrast, and warmth of your subject layer to better match the new environment. Some apps, like Adobe Express, have a “Match Color” feature for this purpose.
If the final composite looks fake or “pasted on,” add a slight blur to the new background. This mimics a shallow depth of field, making your subject pop naturally. Also, consider adding a subtle shadow behind your subject. Many editing apps have a “Shadow” tool where you can adjust angle, opacity, and blur to ground your subject in the new scene.
Pro Tips for Best Results Straight from Your Camera
The best editing starts with the best original photo. When you know you’ll want to change the background later, use your S23 Ultra’s Portrait Mode. This mode uses the laser autofocus system to create a depth map, which makes separating the subject incredibly accurate. The phone already stores the background data on a separate layer.
Shoot against the simplest background possible. A plain, contrasting wall is ideal. This gives the AI the clearest possible edge to detect. Avoid busy patterns or backgrounds similar in color to your subject’s hair or clothing.
Ensure your subject is well-lit. The S23 Ultra’s excellent HDR capabilities will capture clear detail on your subject, which prevents the AI from creating jagged or fuzzy edges during the cut-out process. Natural, even light is best.
Your Creative Potential Is Now Unlocked
Mastering background replacement on your Samsung S23 Ultra opens up a new world of creative expression and practical photo correction. You can create professional assets for work, stunning personal art, or simply have fun placing pets in improbable locations.
Start by experimenting with the built-in Gallery tools to understand the AI’s capabilities. Then, explore a third-party app like Adobe Express when you need more control or inspiration from templates. Remember, the key to a believable composite is attention to detail—matching lighting, refining edges, and choosing a context-appropriate background.
Your phone is more than a camera; it’s a portable studio. Grab your S23 Ultra, find a photo you’d like to transform, and follow these steps. Within minutes, you’ll have a completely new image, ready to impress.
