I'm a current owner of an LG G4 and after upgrading to Marshmallow the Bluetooth audio connection in my Infiniti Q50 is unusable. I started a thread and at least 15 people on this forum have the same problem and more people from other forums have it as well. It is a MM problem and confirmed by LG but no updates have been put out to fix it (it's been a couple months). I ordered a V10 which should arrive in a day or two and I'm wondering if anyone else has experienced MM Bluetooth issue yet? A little worried about updating to MM and having the same issue on the V10.
