For saving screenshots of tech or just trying to talk someone through their settings, I’ve been doing for awhile.
For my iPhone 7 it’s been home button and power button. Works with iPhone 8 backwards.
Sometimes it’s just easier to do a screenshot for problems, or showing someone what you see.
Especially if they may be using different tech.
If interested Android and iOS instructions are included in link.
