Shadow and Detail distance on android

Hi Unity 4.2 released and i am adding realtime shadows on my game. But i have problem. I dont know how to change detail distance, you can see what i am saying. This screen shot has taken on android device. Galaxy s3 is casting only near objects shadows. I am changeing shadow distance from quality settings but it is not working. Everything is normal on editor. What must i do in order to cast all objects shadow at far distace
