The missing evidence is specific
Knowing that the fingerprint reader sits in the side button establishes a hardware fact, not a screenshot shortcut. Reusing the Home-button procedure because both devices say Touch ID would skip the model check that makes an instruction trustworthy.
This page therefore does not publish an inferred button combination. The linked Apple support article remains useful context, but its current model scope must be checked again when Duo-specific documentation is available.
Before capturing a screen
Consider whether the visible content contains account details, messages, financial information or confirmation codes. Crop or redact personal information before sharing it, and do not assume a support request requires a full unedited screen.
An open foldable can display more than one task. Confirm which content you intend to share and review the resulting image. PhoneHelp has not verified whether any Duo-specific capture behavior differs between its two screens.
What would make a shortcut publishable
We need an official instruction that clearly applies to Duo or a carefully documented, independently verified device-specific procedure. It must state the applicable software and distinguish ordinary capture from a full-page or app-specific feature.
- Exact model and software applicability.
- A confirmed instruction rather than a familiar-looking diagram.
- Clear limits on what the capture includes.
No shortcut is better than a misleading one
If you need assistance before that evidence is available, use Apple’s current device support and explain the exact model. Do not hold unrelated buttons repeatedly on the assumption that one sequence must work.
This is an evidence-gap guide, not a claim that Duo screenshots are broken. The absence of a verified instruction in our review is not evidence of a product fault.
