Samsung is getting closer to taking the wraps off its foldable smartphone, a prototype of which has supposedly been in the works for years now. In a tweet sent late last week, the company teased a big reveal of the device, or at least a prototype version of it, describing its upcoming developer conference as “the crossroads between the present and the future” and showing a subtle graphic of two lines unfolding into a right-facing arrow.

We’ve been hearing for a while now that Samsung was close to showing off its foldable phone. Samsung CEO DJ Koh hinted in an interview with CNBC in September that the product could arrive as soon as this year, but we still haven’t seen any hardware, even in just the prototype phase.
