Shader not rendering on mobile.

Hello guys, I have a shader that I wrote and it renders fine on my mac. However when I build my app and run it on mobile, everything in the scene that uses my shader is invisible. Like its not rendering them. What have I done wrong?

Code (JavaScript):

1. Shader "UnlitColor" {
2.     Properties {
3.         _Color("Color", Color) = (1,1,1,1)
4.     }
5.     SubShader {
6.         Pass {
7.             Tags { "LightMode" = "ForwardBase" "Queue" = "Opaque" }
8.             Cull Off
9.             CGPROGRAM
10.             #pragma vertex vert
11.             #pragma fragment frag
12.             #include "UnityCG.cginc"
13.      
14.             fixed4 _Color;
15.             fixed4 _LightColor0;
16.      
17.             struct vertexInput {
18.                 fixed4 vertex : POSITION;
19.                 fixed3 normal : NORMAL;
20.             };
21.      
22.             struct vertexOutput {
23.                 fixed4 pos : SV_POSITION;
24.                 fixed4 posWorld : TEXCOORD0;
25.                 fixed3 normalWorld : TEXCOORD1;
26.             };
27.      
28.             vertexOutput vert(vertexInput v){
29.                 vertexOutput o;
30.          
31.                 o.normalWorld = normalize( mul( fixed4( v.normal, 0.0), _World2Object ).xyz );
32.                 o.posWorld = mul(_Object2World, v.vertex);
33.                 o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
34.          
35.                 return o;
36.             }
37.  
38.             fixed4 frag(vertexOutput i) : COLOR {
39.                 fixed3 diffuse = saturate( dot( normalize( i.normalWorld ), normalize(_WorldSpaceLightPos0.xyz)) * 0.5 + 0.5);
40.                 diffuse = _LightColor0.rgb * diffuse.rgb * _Color.rgb;
41.  
42.                 return fixed4(diffuse, 1.0);
43.             }
44.             ENDCG
45.         }
46.     }
47. }
48.  

Note: I added a fallback but that didn't solve it.

Using a nexus 4

 

Shot in the dark, try changing all your fixed to half.

 

Tried that, didn't help.

 

Have you tried any other device? and what is the device?

 

I tried an HTC one, don't know what version but I had the same issue.
