while playing video in galaxy s7 edge,distortion seem to occur on the edge part. Help me?

Samsung Galaxy S7 Edge device supports Curved full screen while playing the video. Due to curved edge screen’s design character, you may feel video on edge screen is specially distorted. But, this is not device faulty but natural operation caused from curved edge screen and does not affect device performance. And, the colors on the curved screen may look different depending on your viewing position.

Due to a phenomenon called WAD (White Angular Dependency) which is due to the inclined curved surface of the S7 Edge screen, the color at the edges display more darkly. For an AMOLED display, the WAD phenomenon results in the color white sometimes appearing to have a Green tint, or on occasion a Blue or Yellow tint when viewing the AMOLED at an angle. Due to WAD phenomenon like this, you may feel video on edge screen is specially distorted but it’s not device faulty but normal operation by device design concept.
