BlendOp not working on Nexus?

Hello
Is it just me or can anyone else confirm if BlendOp Max/Min is working on Android/Nexus (I don’t have another device handy ATM)?

Shader "Lighten"
{
	Properties
	{
		_MainTex ("Base (RGB)", 2D) = "white" {}
	}
	SubShader
	{
		Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
		ZWrite Off
		BlendOp Max
		Blend One One
		Cull Off
		Lighting Off
		Fog { Mode Off }

		Pass
		{
			SetTexture [_MainTex]
			{
				combine texture
			}
		}
	} 
}

The above shader works as expected in the editor, on web builds, but on the Nexus 7 tablet (Android 4.2.2), the geometry shows pink, as if the material was missing or unsupported.
I’m using Unity 3.5.7f6

first of all Android/Nexus is not enough to determine phone
second - in the logcat we spill all gl ext present - check for GL_EXT_blend_minmax. i dont remember 3.5 but in 4.x we check for that ext if min/max blending is available on device
