Going by the teasers it is expected that the smartphone might feature a display with 18:9 aspect ratio, similar to what was first introduced by Samsung and LG which are priced very high. Also, the screen edges are curved and there is no visible button at the front, which confirms that the smartphone may use on-screen navigation keys and house a bigger screen of 5.7 Inch ( Not Confirmed).
Currently, Samsung leads bezel-less screen smartphone market with its Galaxy S-series devices. The current flagship handsets – Galaxy S8 and Galaxy S8+ — redefined the bezel-less equation by eliminating the side bezels and reducing the top and bottom bezels exponentially, which allowed the company to use bigger screens in compact form.
