I just got a G4, and am trying to transfer stuff from my G3 to it using the built-in LG Backup. For some reason, the G3 cannot find the G4, even though I have the G4 set up to receive (and it currently waiting) and have the G3 set up to send (it's on Searching New Device, and not finding anything). I have tried this both with and without NFC, and nothing is working. What am I doing wrong? I would prefer to not backup everything with Helium and a SMS backup app if I don't have to.
