Devloping for other general VR devices(mobile)

So I own a Procus One headset.

I am developing a VR app on unreal engine 4 and I want it to work on nearly all VR devices not just locked to Google or Gear VR.

For testing I am using the Google VR plugin there is a bit of field of view off but apart from that it looks fine.

Should I use any other plugin to make a general purpose VR app?
