Yah, my current unit is a refurbished warranty replacement. Original unit I won, so I have yet to actually pay for this phone. The original got hit with boot loop which is why I have a replacement. Thing is wonky though. Like others have noted, BT and WiFi are not reliable (good grief #LG, it is 2016 - how you can you not have figured out wireless connectivity yet?). The phone has been choppy and lagging too. I think it needs a reset. I can't remember if this unit shipped with M or if it was updated. AT&T pushed M to the G4 in February or late January I believe. I'd have to look up when I got my replacement.
Big "again": It was a free phone. No idea what I'll eventually replace it with. Love the V10 and long term reviews are good. I am still technically paying off my G3 (one more payment). I did a factor reset on the G3 and then it got M and has been working great. Between the two phones, I'll probably be okay past the release of the Note 6 in the fall.
