Has anyone yet experienced a crack in the body of their LG G3 around the microphone hole or the IR blaster? I've only used mine for a few weeks, but so far so good.
Sorry to grave dig but I have this same exact problem. It's a device design defect, LG is aware of it but anyone on contract is meant to go through their carrier to resolve this. It just showed up a couple weeks ago, I've been hesitant trying to see if I can get it replaced because I know Sprint will want to charge me even though it's not from user neglect, it's a design flaw. The phone was designed with that thin curve and because of it the material they used it eventually cracks, I guess it starts from the mic hole because it's the weakest points on the device.
