After some searching on the wireless topic I found this website http://www.qinside.biz/en/support/qi-enabled-phones-2015
which show which phones have wireless charging and which don't. The thing that suprised me was that the LG G4 is Qi Intergrated.
I have the LG G4 H815 (international model, I think)
From what I heard at launch the lg g4 did not have wireless charging and was supposed to have them later on (don't quote me on that)
Is it possible that my model ( bougt about a week ago) has wireless charging??
