It appears that LG is the only company to dare offer real innovation on its flagship models. I don't know how well this model will do but it seems it's not just a faster rehash of last year's model.
Still using G2 more than 2 years after I first got it. Battery life seems to be a bit less now than when I first got it but the phone still does what it's supposed to do without any issues. Only had to do a Factory Reset when it upgraded to Lollipop. I see me upgrading to the G5 since its closer to the G2 in terms of size. I found the 5.5 inch screen of G4 too big for my liking.
Agreed -- the G3 is the best Android phone I've owned in my 6 years of owning Android devices, and will be the first one I use until it doesn't work anymore, as opposed to upgrading on the 2 year cycle.
Exactly my same mentality for now, although I do want to get into Google Fi which only allows specific phones (due to how their network works) so I may have to try a phone that might have faults.
I have an LG Nexus 5 : common fault is that microphone stops working and power/volume buttons gets stuck (in my case due to case breaking near buttons from being in pocket). I have given Moto G phones to parents and friends - they seem more reliable.
To be fair, Samsung have offered some innovative features on their high end phones. Best example I can think of is the Galaxy Beam. The Galaxy Note was different when it was first released. The Galaxy Edge is slightly unconventional too.
At most, I think you mean specifically this year, for android phones. The iPhone 6S had some cool (hardware) updates, and I'd venture a guess that the iPhone 7 will, too.
Well, the only thing on the 6S that isn't an incremental upgrade is the force-sensitive touchscreen, which in my opinion doesn't really bring that much new to the table compared to this kind of modularity.
