I havent had any bootloop issues with mine
Did they fix the bootloop issue with the G6's? It was an issue with all the other G series LG's upto 5. Always something that has highly put me off them as I had a G2 and G3 that both got bootlooped and LG refused to touch them or acknowledge my claims. Edit: The LG G6 does have a bootloop issue but nothing bad at all just a simple fix of connecting it to a pc and holding a button or two. So with that I say great deal!
I have this phone and it is really good. The battery lasts 36-42 hours with just normal browsing/Facebook, etc. The snap dragon 821 coupled with 4gb ram makes this phone very quick (things load instantly). This is my first Android phone too, and I would highly recommend this to anyone.
I wouldn't take it as a sign at all... All part of planned obsolescence.
Reviews were good a year ago when this was going for £400+ so for less than half that I think it's a very decent deal. If I had the cash I would be tempted
