Samsung Galaxy S Problem

I am making a new game. It works find on my Galaxy Note 2. I load it on my Galaxy S (original) and it doesn’t get past the Unity splash screen. I just get a blank screen and nothing more.

It is a pretty simple 2D game. I do use low poly 3D models and lots of planes with textures. I am also using NGUI if that helps.

Can anyone tell me how to fix it?

It looks like this is some kind of a memory issue. I reduced the images that are in my Atlas until the size of the texture was < 16 mb and now it works on these older devices.
