I thought I have to post this because it has been days of me trying to take a simple image screenshot with my phone. I learned how to take a screen recording before I learned how to take a screenshot. Taking a screenshot with my Samsung is done several ways. One, you could press the power button and the volume down simultaneously. Two, you could press the Bixby button and let the genie out of the bottle and say a wish (kidding), say "Bixby take a screenshot." Third, you can use the S-pen and click to access S-commands then choose Screen write. The S-pen path is recommended if you're going to write on the image, or annotate it.
