Weird Blotches older Android

I am getting some weird blotches on older Android devices especially Samsung. These are untextured models coloured white (legacy diffuse or Standard material same thing). Once I add color to them the problem goes away. Works well on PC and newer Android phones. This is in Unity 5.

I tried everything, disabling GI changing all check boxes and lighting properties. I am loosing it please help.

Just in case someone else runs into this issue, I solved it by giving a separate instance of a white material to every object (in a Start() script). I still don’t know why this happened and its unfortunate that this thread got no attention but at least its fixed in my game.
