Worked example and checks

Choose a supported input method and check what it actually does on your phone.

Identify the device first

An iPhone with Face ID and an iPhone with a Home button use different screenshot combinations. A configurable feature such as Back Tap or an Action button assignment also depends on model support and settings. A title containing a recent year does not establish compatibility.

Create a support screenshot

Open a sample screen without private messages. On a Face ID model, briefly press Side and Volume Up together, then release. On a Home-button model, use Home and the Side or Top button appropriate to that device. Open the captured image and check its contents before sharing.

Test a configured gesture

If you want a gesture to trigger an action, inspect the relevant settings and select the action explicitly. Try it while stationary on a sample screen. Check whether your case, motion, or current app affects recognition. Do not treat a configurable gesture as something every iPhone has enabled.

Keep recovery actions separate

A screenshot, a restart, and an accessibility action use different inputs. Look up the exact model's instructions before attempting a recovery sequence. For an error report, include the app, iOS version, steps that led to the problem, and a cropped screenshot. Those details are more useful than an image without context.
