Samsung’s Camera watermark setting won’t remove a mark from a photo you’ve already taken. To try removing it from the image itself, open the photo in Samsung Gallery and use Object Eraser, if your phone offers it. The tool fills the area where the mark was, so inspect the result and keep the original; Samsung does not guarantee a clean reconstruction for watermarks.

Remove the watermark with Object Eraser

  1. Open the original image in Samsung Gallery.
  2. Tap Edit, then find Object Eraser. Depending on the phone and software, Samsung documents it under either the Intelligence features (three stars) icon or the rightmost four-circles editing icon.
  3. Tap or draw around the watermark, then tap Erase.
  4. Check the filled area at normal size and zoomed in, especially where the watermark crosses text, a face, a straight edge, or a detailed background. If the fill damages nearby detail, undo or revert and try a smaller selection.
  5. Save a copy if that option is available, leaving the untouched original intact.

Samsung’s US Gallery instructions describe Object Eraser as a way to remove unwanted details and fill the missing area. Using it on a watermark is a practical application of that general tool, not a specific Samsung promise that every watermark can be removed cleanly.

Choose between erasing and cropping

Option Best when Trade-off
Object Eraser The tool is available and the area behind the watermark can be plausibly filled. It may leave visible artifacts, particularly over complex detail.
Crop The mark sits at the edge and removing that strip won’t cut off something important. It changes the framing and reduces the image area and dimensions.

Samsung’s US A-series editing guidance documents Gallery cropping. If Object Eraser is absent or its fill looks worse than the original, cropping is worth considering only when the lost framing is acceptable.

Why the Camera watermark setting won’t undo an existing mark

Samsung’s support guidance says that once a camera watermark has been applied, it cannot be deleted or removed through the watermark feature. That refers to the Camera setting; it does not mean an editor cannot alter the visible pixels. Turn off Camera > Settings > Watermark to prevent the setting from adding a watermark to subsequent photos, not to change existing ones.

If Object Eraser is missing

Menu names, paths, and feature availability vary by Galaxy model and software or app version. Samsung’s US A-series guide lists Object Eraser for the Galaxy A26 5G, A36 5G, and A56 5G, while its separate A27 5G instructions show a different Gallery route. Check the Gallery editor and your phone’s current software and app version rather than assuming every Galaxy has the same controls.
