I would exchange it with the retailer given it's only 2 days old.
You know that the PS VR is sould out pretty much everywhere right now? :/
What games does this happen in?
I noticed in a few games, when I approached the "out of play" area it would start to get darker the closer I got to the edge of the play area. Then go completely dark before getting the out of play message.
It has happened pretty much with all the games so far. :/ And it really feels like it's some kind of connection issue because it also cuts the sound off from the headphones. Oh well.
