Cannot run simple project with smooth move

i have problem running my test scene on my Android devices. i have a background sprite and a player sprite. player moves linearly from one corner to another. there is glitch(jump) on player movement.i tested it on 3 android tablets+phone. when i tested it with nokia lumia 925 it works perfect. can you check this project with your android device?
