Just think about it. Do you really think that LG will say officaly: "NO NOUGAT UPDATE FOR OUR 1.5 YEARS OLD PHONE". It would be a really good advertisement for them! Lets be critical. It's the same like if they said: Buy our current flagship - G6 and you will get terrible support, bad build quality, bootloop problem after a year, you will loose all your date when we change phones motherboard, you will wait many days and finally you will probably stuck on 7.1.1 forever. It's almost on 100% that LG G4 won't get Nougat update. All what they need is to sell new models. That is what keeps them alive. Building a new system for almost 2 years old phone is nonsense, it is, it cost money. We need to earn money, not spend money. If you want Nougat, buy LG G5 or get G6. Thats it. But many people will buy from another phone manofacturer next time after this. LG is digging it's own grave for a long time.
