Thank you!!

Thank you

Thank you, I didn't know that

Thanks for the information.

The instruction I've found googling all say this:

Take a screenshot or screen recording on iPhone Xs

Do one of the following: On an iPhone with Face ID: Simultaneously press and then release the
. . . . . . side button and volume up button.
Tap the screenshot in the lower-left corner, then tap Done.
Choose Save to Photos, Save to Files, or Delete Screenshot.

It doesn't work for me. When I press those buttons it simply turns the phone off.
