Fixed Orientation Lock
Apps should support both portrait and landscape orientation unless a specific orientation is essential.

What this rule checks
The scanner reports apps that restrict viewing to a single orientation (portrait or landscape only).
Why it matters
Users with devices mounted to wheelchairs, or with motor conditions that make rotating a device difficult, have no choice about their screen's orientation. An app locked to portrait is simply sideways for a user whose device is fixed in landscape. WCAG 1.3.4 requires content to work in both orientations unless a specific orientation is essential.
Common failure patterns
- a blanket portrait lock applied at project creation and never revisited
- individual screens locking orientation to simplify layout work
- video or camera screens locking orientation without restoring it afterward
Remediation guidance
- support both portrait and landscape orientations unless there's a valid reason to lock one
- if locking orientation is required, provide alternatives or ensure the design accommodates various accessibility needs
