Half of the screen does not seem to work correctly

I am not such a professional coder but trying to code something on Unity. However, when I try to play the application on my android phone, the half of the screen does not seem to work correctly, please look at the photo: http://i.imgur.com/J7Bgn5i.png & http://i.imgur.com/aV3aeyh.png

Can you guess what the reason is for that?

Up to now, I have changed screen resolution but it did not solve my problem.

By the way, It works perfectly on my android tablet. However, as I said, I have this problem on my LG G3 android phone.

Thanks for your help!
