Hey, I have completed developing my 2D game for android and everything was working fine in my unity editor. But when I build it for android and installed it on my android devices the following problems came into play : 1. For some android devices ,only half of the screen is showing,for other half my game object is invisible. 2. In my unity editor,everything is running fine but for android devices buttons are not working correctly . Sometimes they work and sometimes they don't. 3.Also levels are loading slowly but when i am testing it using unity remote from my computer everything seems to be fine. Can anyone please tell me how to fix this issue ? Is there is any way or build settings that i can use to get rid of this problem?
