Press Side Button + Volume Up
0:22
Press the Side button (right edge) and the Volume Up button (left edge) at the same time, then release both quickly. The screen flashes white and a small preview thumbnail appears in the bottom-left corner.
This works on every iPhone without a Home button - iPhone X, 11, 12, 13, 14, 15, and the SE. On older iPhones with a Home button, the combo is Home + Side instead.
Tip
If you accidentally hold the buttons too long instead of tapping, you'll trigger the Emergency SOS slider. Quick press, quick release.
