Why my skylight HDRI and IES spot light not recognized in the android deployment ?

Hi guys ,

So i finished developing a VR apartment for samsung Gear and added skylight with HDRI and IES spotlight and point light , after the build is finished and applying all the SDK settings for VR i have packaged the project to ETC2 and opened successfully ins the s7 but without the HDRI light and shadow and the IES spotlight , the only light that was active was the point light , so what did I do wrong , or is unreal engine dosnt support hdri and ies for android ??
