Hey guys im pretty much new to this forum so sorry if this is the wrong place to post this kind of things, but i recently purchased a brand new LG G4 Leather back (black) and i put the LG G4 on a hard surface, it made a small impact, and a hairline cracks starts to comeout beside the headphone jack. i heard that the G3 had this build issue also, is this going to be another issue for the LG G4 ? just sharing.. thank you guys
