EventSystem Not Working (Help Please)

Hello,
I did everything needed to setup my EventSystem (My game is for android) and on PC the buttons and are working perfectly fine, but on phone its a whole new story.The buttons arent aligned as it is on PC, and when I click on the button my hero moves too as I dont have an IsPointerOverGameObject...Please tell me what I am doing wrong, thanks.(This is my Player script and the buttons are from the standard assets)
