Can you use iPhone Duo without unfolding it?

Yes. iPhone Duo can be used while completely folded, with its 5.4-inch outer display providing a conventional iPhone experience for everyday tasks.
Users do not need to open the device every time they want to send a message, check notifications, make a call, use Maps or open an app. The outer screen is a full display rather than a small notification panel.
Opening iPhone Duo reveals the much larger 7.6-inch inner display, which is intended for situations where additional space is useful, including multitasking, games, video and other content.
When do you need to unfold iPhone Duo?
There is no requirement to unfold it for normal iPhone use. The decision is largely about screen space. Quick tasks can remain on the outer display, while opening the device provides the larger canvas and foldable-specific features.
This means iPhone Duo can effectively switch between a compact phone and a small tablet-like device without requiring users to carry two separate products.
