The Galaxy S10 was the company's first phone to include a "hole-punch" cut-out in the display, but Yang says that eventually, the selfie camera will be placed underneath the display itself. While the company hasn't revealed any timescales for such a device, Yang did say that it "wouldn't be possible" within the next one to two years.
The company has jumped quickly from notches, to hole-punch, to folding phones, so a total display device is certainly in keeping with Samsung's bold aspirations. Unfortunately, it's rarely the first company to get their ambitious ideas to market. However, this isn't the first time Samsung has discussed this kind of technology -- it was mentioned in a presentation given in October last year -- so even if we don't see a full-screen device within the next two years, Samsung has already got the ball rolling.
