Level AA

Don't lock display or operation to a single screen orientation, whether portrait or landscape. Users who mount their device -- on a wheelchair, for example -- may not be able to rotate it. An exception applies when a specific orientation is essential to the function itself, such as a piano keyboard app or check-scanning.
