The nexus 6p was defenetly the device of the year 2015 and still is the best option on the market, the keyword is still, but as it gets older if you are as unlucky as me to damege it and meet the atrocious service / repairs policy of google and huawei you would stay open minded for a swich.
My latest history was Sgs3 ( great device )--> Sgs4 (small diference between Sgs3 and ditched it after 30 days of use) --> htc m7 ( awesome device best of 2013 in my oppinion) -- > Sgs5 ( it felt like a bigger Sgs3, or a diferent colour Sgs4 diched it after 2 weeks ) -- > LGG3 ( a game chager, I loved that device also phone of the year 2014 in my humblle oppinion). Passed the LGG4 (It did not feelt like a big upgrade from the LGG3) almoust bought the Sgs6 edge +, but changed my mind in the store in the last minute, it's sexy porwerfull, inovative but also wery gimmicky, and decided to wait for the Nexus device ... the 6P as we know it, and it proved a very wise and inspirated decision, the device is fantastic, a dream gadget, a marvel of tech, nothing but love, until... ...I broke it and had to go through the nighmare of service, I had broken phones before but all went relatively well, I would have never forseen it would be sutch a ordeal.
So yeah I am looking forward to see the LGG5 it has to be great after the relatively forgetteble LGG4, and LG are capable of inovation and greatness, I still love my ex LGG3 . the LGG5 defenetly on my radar... also looking forword to the HTC M10, HTC has to deliver if it still wants to stay on the market after the relative consecutive flop of the M8 and the disgrace M9, its all in for them, and a company that has nothing to lose in a last effort to grateness of death has if not my interest my attention. The Sgs7 is just the Sgs6 kid whit the Note 5... inbreeding, never a nice thing
