Yep, my Nexus 4 was not fit for use. It barely worked, and actually did stop working after six months. I'm very hesitant to buy another Nexus phone. Though the Nexus 4 was made by LG, I found other LG phones aren't that bad. The G4 was a pleasure to use until the CPU died--I'm told the CPU dies on nearly all LG G4 handsets.
My conclusion from this admittedly small sample size: there is little Q/A on Nexus phones, and their design and build quality compares poorly to a phone whose production is entirely controlled by an established manufacturer.
