Unlock your Samsung S23 and navigate to the screen you want to capture.

Press and hold the volume down button and the power button simultaneously.

You'll hear a camera shutter sound and see a brief animation to confirm the screenshot.

Release both buttons to complete the screenshot.

A preview of the screenshot will appear briefly on your screen.

You can access and edit the screenshot from the notification panel or the Gallery app.

To capture a scrolling screenshot, take a regular screenshot first.

Then, tap "Capture more" from the options that appear at the bottom.

Keep tapping "Capture more" to scroll and capture the entire content.

Once done, you can edit or share the scrolling screenshot as needed.

To access your screenshots later, open the Gallery app and go to the "Screenshots" folder.

Now, you have successfully captured and managed screenshots on your Samsung S23.
