Player dissapear for no reason after build and run.

I creat a game for Android, im not use TouchButtonLogic , im using normal OnMouse_ and Input.GetMouseButton_ . Its working perfectly in the game editor. But for some reason, when i build and run it on my device , my player was lost when i build and run the game. My player is Instantiate when i press a button call "Deploy". When i deploy its there is some mesh to go with it for good visual . When on my device , when i press "Deploy", there is the mesh but no my player. I dont know why. Then i remove the player Script component to check if my MouseStimulate is the problem? But the player still missing. Thanks for reading and thanks for the help.
