Folding phones will (literally) add a new dimension to how we interact with our phones, and Android is working to make that possible.

At the summit, Android VP of Engineering Dave Burke said that he expects to see foldable devices from several different Android manufacturers. He also called out Samsung, saying that Android and Samsung are working closely together on a device planned for an early 2019 launch. Burke is probably referring to the foldable Galaxy phone, which Samsung also announced Wednesday.
