Smartphones have become a bit predictable over the past few years, leaving consumers craving something new to send them running to stores for an upgrade. For years, Samsung has teased the possibility of a phone with a folding screen that can expand to something more like a tablet. A new interview with the company's mobile chief indicated the wait may finally be drawing to a close.

Samsung's DJ Koh, chief executive of the tech giant's mobile division, recently told US network CNBC that the company is planning to unveil a consumer model of a phone with a foldable screen by the end of the year. Koh made his remarks at the IFA show in Berlin. While he didn't give a firm timeline for when the smartphone would make its debut, CNBC said it's likely a first glimpse will come during Samsung's developers conference in November.

Samsung did not immediately respond to a request for comment.

The company has previously shown off its folding phone concept at CES, the industry's annual Las Vegas consumer electronics trade show. In its 2011 keynote address, Samsung revealed plans to make a folding phone. As recently as last year, it showed a folding phone prototype to some members of the media. The company has used flexible screens, which wrap around the edges of its phones, for years. But it has never released a phone that completely folds or a screen that people can bend themselves.

It's not clear when a folding phone would actually go on sale to consumers, but this is the closest Samsung has ever come to setting a date.
