Mobile devices today come in different form factors - tablets, phones, watches, even televisions. We design our apps to adapt to these device affordances but we assume that each device has a fixed form factor and capability. What if you had a mobile device with multiple screens that could support different postures? Does that change your design-development thinking?

In this talk I'll introduce you to the features and functionality of the Microsoft Surface Duo, explore the emulator, and talk about how you can adapt your existing apps to leverage the power of flexible layouts (that can span screens) and hinge events (that define device postures) - with code examples. We'll wrap up by exploring best practices and design challenges for creating new and innovative dual-screen experiences - with a review of relevant resources to jumpstart your journey rethinking the modern mobile app!
