Bought a LG G3 on the strength of their Nexus 4 offering. Turned out to be a terrible phone.
Battery life was shockingly bad and GPS was terrible. Considering the two big things I use my phone for is Ingress and Viewranger (both big battery and GPS using apps) there was no way I was going for a G4.
