I got google cardboard. It works flawlessly. You may get it from Amazon at about Rs200.
See for a clear VR video you need more than 500ppi resolution screen. Else due to convex lens in the VR set, you will see the pixels. SO for that awesome quality you need to buy high end phones like LG G5, Galaxy S7 etc. Now as this one has Full HD, so you get watchable images in this screen. Far better than HD screen.
Anyway, do not waste much money on VR as you will get bored. Further ANTVR does not have that magnet I suppose which you will need for controlling the device while it is attached to the VR set. Anyway, all types of VR will work with this phone. Get card-boared, and if you feel a VR is necessary, buy a better one. Watching clash of clans in 360, beautiful Japanese girls dancing all around you and watching 360 porn are some of the wonderful things you can do with VR. Also the most awesome feature of this phone is the Fast charging. Just 20 mins charging gives me more than 60% charge. and this phone does not gets hot. Also its design is much better than Xaiomi Redmi. After and update, now battery lasts more than a day. Initially I was getting disappointing battery performance. Now its awesome!!. Camera clicls very sharp picture. Also the front camera is wide angle. And the Infrared remote. Now I don't have to search for the AC remote at office or TV remote at home. My phone easily servers the purpose.
I was planning for a iPhone but now I feel completely satisfied with this phone. I got it for Rs 7600 exchanging my old Samsung which cost RS 24 k and didn't last even 2 years.
