A smartphone with an expanding display that can grow and shrink on demand has been demonstrated by Chinese phone-maker Oppo.
The device has a flexible display that rolls up inside the device, letting the screen expand from 6.7in (17cm) to 7.4in (18.8cm).
BBC Click’s Chris Fox went hands-on with the concept phone to see what it was like.
