That concave smartphone above is the Samsung Galaxy Round, it is launching tomorrow in Korea under the SK Network and it features a slightly curved 5.7-inch OLED screen with a 1080p HD resolution. Aside from the unique curvature of the screen, which is oddly similar to some HDTVs that we're seeing this year, the Galaxy Round will offer some software tweaks to enhance the screen's use. If it is on a flat surface, simply push down on the Galaxy Round to tilt it up slightly and it displays time and notifications. The new phablet-sized device will cost the equivalent of $1,000. No word on yet on North American availability.
