In a bid to get as many developers on-board before its foldable smartphone hits the market, Samsung showcased its foldable display to everyone attending its developer conference in San Francisco. When developing for a mobile device, developers need access to information such as screen resolution, and that’s exactly what Samsung has provided at a hands-on session at SDC.

Two screens, different resolutions

Samsung’s foldable device will have a 7.3-inch display when it’s open to offer a tablet-like viewing experience. When folded, users will have access to a 4.6-inch display on the outside. This 4.6-inch outer display has a 21:9 aspect ratio and a resolution of 840×1960 pixels, which translates to 420 ppi pixel density. The 7.3-inch display carries a resolution of 1536×2152 pixels and the same pixel density as the outer display. Apps used on the outer display will expand to occupy the 7.3-inch main display when the device is unfolded, and users will also have the option to use three apps in tablet mode.

Naturally, Samsung isn’t willing to reveal the entire spec sheet. The company also refrained from showing the foldable device completely on stage. Since there is no word on a launch date yet, there is a chance the specs could change in some way as development goes on.
