Mobile/VertexLit shaders broken with Unity 5.2.2 + Lollipop
The built-in "Mobile/VertexLit" and "Mobile/Cutout/VertexLit" shaders work differently in different circumstances on the Note 4 N910G (I don't have an S6 to check) :
Unity 5.0.2p2, GLES2, Android 4.4.4: Shaders work normally in editor and on device.
Unity 5.0.2p2, GLES2, Android 5.1.1: Shaders work normally in editor and on device.
Unity 5.2.2p1, GLES3, Android 4.4.4: Shaders work normally in editor and on device.
Unity 5.2.2p1, GLES3, Android 5.1.1: Shaders work normally in editor, but are extremely dark on device.
(This is with non-static objects using a single realtime light.)
