Before we get started, it's helpful to understand what each function does. The Object Eraser removes unwanted elements and also offers two valuable extras: shadow removal and light reflection removal. Generative Editing with Galaxy AI goes a step further, analyzing the photo and regenerating the background by moving or removing elements. It even allows you to expand the canvas to add space around the subject and fill in any gaps seamlessly. Both tools complement each other perfectly and together cover everything from quick touch-ups to more in-depth creative changes.
Before you start: Prepare your Samsung Galaxy S
To achieve the best quality and compatibility, it's essential to keep your system and apps up to date; this prevents errors and allows you to benefit from the latest AI improvements. Updating takes less than a minute and makes a significant difference in performance and stability.
- Open Settings and go to Software Update. It is the starting point for checking new versions.
- Click Download and Install and wait for the system to search for updates. If there is a new version, follow the wizard.
- Complete the process by following the on-screen prompts. Do not turn off the device while updating.
In addition to the operating system, keep your Gallery app and any camera-related photo editing modules up to date. The more recent the software, the better you'll benefit from processing and AI improvements. An updated Gallery app ensures compatibility with features like Object Eraser and Generative Editing.
What is the Object Eraser and how far does it go?

The Object Eraser is a native Gallery tool that lets you select an object in an image to remove it. AI analyzes the surroundings and reconstructs the background to seamlessly integrate it. It's ideal for removing people from the background , cables, papers, signs, stains, or small, distracting imperfections. Its goal is to erase without leaving a visible trace.
Alongside this feature, you have two very handy shortcuts: shadow removal and light reflection removal. With both, the AI detects these visual artifacts and automatically reduces or eliminates them, which is especially useful in backlit scenes, interiors with glass, display cases, or shiny surfaces. Perfect for scenes with harsh glare or harsh shadows.
Generative Editing with Samsung Galaxy S AI: The Creative Option
Generative Editing with Galaxy AI analyzes the scene and regenerates it as you move, resize, or delete objects, and realistically fills in the background when you zoom in. It's the Swiss Army knife of mobile editing: reframing, more balanced compositions, and coherent backgrounds without the hassle. It allows you to fix framing issues and correct cropped elements very naturally.
One of its strengths is expanding an image to create more space around the subject; you stretch the edges and the AI seamlessly reconstructs the surroundings. Furthermore, you can reposition an element and let the system fill in the gap with the appropriate background, drawing the eye to what's important. It shines particularly well on uniform backgrounds, and it often provides significant improvements in complex scenes.
It's intuitive to use: simply select and release, and the AI does the work in the background. If the result isn't quite right the first time, you can undo and try another option or adjust the selection to refine the effect. It's powerful editing that anyone can use.
Where are the tools in the Gallery?
Everything is integrated into the One UI Gallery, so you don't need any external apps . Open the image you want to edit and tap the pencil icon to enter the editor; you'll see cropping tools, filters, adjustments, and drawing tools, and the last icon in the editor contains the advanced features. These include the Object Eraser, Shadow Eraser, Reflection Eraser, and Generative Editing.
On devices with One UI 6 and higher, the integration is even more polished and accessible, with a clear workflow directly from the Gallery. If you can't find a specific option, check that you have the latest version of the app from the Galaxy Store or Play Store. Menu visibility may vary slightly depending on the version.
How to erase objects step by step with the Object Eraser
Removing elements from an image is easy if you follow a clear routine; it's worth taking a few seconds to select precisely to achieve a more natural finish. The key is in the selection and working calmly.
- Open the photo in Gallery and tap Edit to enter editing mode. Without this step you will not see the tools.
- Access the advanced tools and choose Object Eraser. The app will prepare the photo for selection.
- Select the item you want to remove: trace around it with your finger or tap on it so the system can detect it. Simple touch usually works very well.
- Click Erase and wait for the AI to rebuild the background. The process takes a few seconds depending on the complexity..
- If you're not satisfied with the result, undo and adjust the selection or repeat it several times. Dividing a large object into parts helps to respect the edges.
- When you're satisfied, save your edit and, if possible, create a copy to preserve the original. Saving as a copy allows you to compare without risk.
A useful trick is to zoom in on the image before selecting; this helps you better define the outline and assists the AI in separating what should be removed from what should remain. The more precise the selection, the more believable the background integration will be.
For large objects or those attached to other elements, try to work in two or three stages instead of all at once; successive passes usually improve the continuity of textures and lines. Patience results in a cleaner finish.
Shadows and light reflections: fix them with a tap on your Samsung Galaxy S
Harsh shadows and glare on glass, metal, or water can be distracting. In these cases, shadow removal and reflection removal features are your best friends. They automatically reduce or eliminate these visual artifacts.
- Open the photo, go to Edit, and go to the enhancement tools. Look for the shadow and reflection icons.
- Select Erase Shadows to soften or remove unwanted shadows. Works very well with well-defined shadows.
- Choose Reflection Eraser to reduce glare on shiny surfaces or glass. It is especially effective in display cases and windows..
- Apply and review the result; if necessary, adjust and reapply. A couple of light strokes are usually better than one aggressive one..
In complex situations, you can combine these functions with the Object Eraser to refine edges or reconstruct small areas with greater precision. Chaining together small corrections often produces a more natural result.
Use the "Lasso" to isolate elements and keep them
It's not all about deleting; sometimes you want the exact opposite: to keep one object and remove the rest to create an image with a transparent background or a cutout for your projects. That's what the Lasso tool is for, available next to the Object Eraser in the Gallery. It lets you isolate elements in seconds.
- Tap “Lasso” and circle the object you want to hold, or tap briefly if the outline is clear. You can select multiple objects if you need to..
- If you make a mistake, use the uncheck option to remove an item from the selection. Complete control over what you keep.
- When you're satisfied, click Next to see the result and adjust if necessary. Some versions allow you to add an outline and choose its color..
When finished, save the image. You can overwrite the original or use "Save as copy" from the three-dot menu, which is recommended to keep both versions. Keeping the original gives you room to experiment.
The extra power of Generative Editing
When the background is complex, the object is tightly integrated, or you want a creative change, Generative Editing makes all the difference. By removing or moving elements, AI regenerates neighboring areas, preserving colors, textures, and perspective so everything fits together. It's especially useful in urban scenes with people or busy interiors.
In addition to deleting, you can reposition a subject to improve the composition: select it, drag it to its new location, and let the AI fill in the gap. You can also expand the canvas if you cropped too much during the shot, gaining space without sacrificing the main content. Ideal for adapting photos to different formats without losing visual consistency.
Tips for results that don't "sing"
Choose the right tool for the situation: if the background is uniform, the Object Eraser is usually sufficient; if the environment has complex textures, try Generative Editing first. Making the right decision from the start saves you time and later adjustments.
Work with zoom to refine selections and observe the transitions in edges and textures. If something looks off, undo and repeat only that area, instead of redoing everything. Local edits minimize visible artifacts.
Combine tools: remove the object, correct the residual shadow, and finish by erasing any highlights. Chaining subtle adjustments together often results in a more believable finish than a single aggressive intervention. The sum of small tweaks makes all the difference.
Make several versions when you're unsure; save copies and compare them carefully to choose the most natural one. Don't rush; an extra minute greatly improves the final result. Your rested eye always detects flaws better.
Recommended workflow
Before touching anything, look at the image and define your objective: removing an element, widening the frame, balancing the lighting, or repositioning a subject. Having a clear goal simplifies the steps and avoids unnecessary edits. A clear intention guides the process.
Start with the basics: remove the unwanted element with the Object Eraser; if there are any unwanted shadows or reflections, address them later. If you're still not satisfied or need to adjust the composition, move on to Generative Editing to rebuild the background or reframe the shot coherently. From simple to complex, this way you have better control over each change.
Troubleshooting common problems
Can't find the Object Eraser, Lasso, or Generative Edit in the Gallery? Make sure your system and apps are up to date in Settings and the App Store. Many features depend on the One UI version and the Gallery version. If a feature is missing, it's almost always due to an outdated version.
If the removal isn't successful the first time, repeat the process with a more precise selection or divide the object into fragments. For backgrounds with patterns or lines, work in sections and validate each step. Patience and precision will solve most difficult cases.
If you're not happy with the final result, use undo and try an alternative, or save it as a copy so you don't lose the original. Experimenting without fear helps you find the version that best suits your photo. Keeping multiple versions is your safety net.
Quality, performance and what to expect
The improvements introduced in One UI 5.1 are noticeable in processing speed, resolution, and final quality: edits are applied faster and with less loss of detail, even in complex areas. On the Samsung Galaxy S23 series, the refinement is evident, with a leap in precision and speed. The overall experience is smoother and more consistent.
As always, the result depends on the scene: simple backgrounds usually turn out perfectly on the first try; intricate environments may require a couple of attempts or combining different tools. The better the original photo in terms of lighting and focus, the better the AI will perform. Good source material greatly increases the chances of success.
Ethics and good use
These features are powerful and open up enormous creative avenues, but they should be used responsibly, especially in informational or professional contexts. If appropriate, be transparent about the edits made. The trust of the viewer is just as important as the aesthetic result.
If you work for third parties or publish in sensitive areas, consider preserving the original file and documenting the most significant changes. Having this history protects your work and facilitates traceability. Editorial honesty is part of good practice.
If you'd like to delve deeper into each tool, continue reading the previous sections and try the suggested steps on your own photos. You'll see that with just a couple of sessions you'll master the mechanics and start effortlessly polishing details. Practice is the best way to internalize the editing workflow.
