Why the background effect may not work well
Samsung identifies several conditions that can make the effect unreliable:

Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →-
The phone or subject is moving.
-
The subject is thin or transparent.
-
The subject and background have similar colors.
-
The subject or background is plain.
-
There is not enough light.
When practical, improve the lighting, hold the phone steady, ask the subject to remain still, and frame the subject against a more distinct background. These are practical responses to Samsung’s listed limitations, not guaranteed fixes. If the subject blends into the scene or has transparent edges, the camera may have difficulty separating it from the background even when the blur slider is strong. See Samsung’s camera-mode guidance and S23 Series manual.

Choose an effect and strength that suit the shot
The effect selector controls the look of the background treatment, while its slider controls intensity. Try a lower strength if the subject’s outline looks unnatural, or increase it if you want a more pronounced separation. Check the preview before capture and wait for Ready; effects and controls available can depend on whether you are shooting a still or video.

The S23 Ultra has a 200 MP main camera, a 12 MP ultra-wide camera, and two 10 MP telephoto cameras with 3x and 10x optical zoom; its front camera is 12 MP. Samsung’s specifications describe the hardware but do not establish that a particular camera selection always gives the best Portrait-mode separation or blur. Choose framing and distance for the composition you want, then judge the Portrait preview rather than assuming one lens is universally best. Samsung Gulf’s S23 camera specifications
