I picked one up as well. QI does not work stock. I believe you need a special cover for it. I found it to be laggy, has horrible signal issues, my camera crashes while zooming and for some reason it says a few of my apps are incompatible. I am bringing the g3 back today and waiting for the x1.
That's what I'd do after owning LG Optimus G, G Pro and G2. G Pro was the best phone LG made but the market went down pretty bad, IMHO.
I think LG makes good product but the software kills it.
There was a post that someone made that Moto X has the best radio in all the recent phones (or last year's flagships).
