Yeah, I also have replacement unit coming way soon. My Nexus 4's plastic side at the chrome band near the bottom left is "mushy"...there's some give and then it creaks, then you press on the screen on the back button and it creaks some more. I put the sim tray with adapter in by accident while i was changing out the sim and didn't want to lose track of the tray during the Thanksgiving activities going on...it wasn't completely in the phone and then my stupid@$$ pushed it in by accident. Just hope LG doesn't think i caused the defect because of the tray being stuck. I got my RMA on Wednesday and they sent me the link to order a new device. How long did it take for you to get the shipping confirmation?
