I think the player is the best player on gearvr.High quality videos supported.But I think the fisheye mode doesn't work well.when I played some afesta 4k videos (circle LR) the fisheye mode can't show the edges of the video correctly and the people in video become small.By the way,the fisheye mode of deovr player can display the video correctly. But deovr has many other terrible problems,hope skybox can support the fisheye mode like the deovr player.
