Everyone gets the security patches. No such thing as certain devices get the security patch.

Then you have received latest patch... many version in Europe, some for AT&T and some for other telco and not surprise the that they are getting patch in different timing..

They have they own center to push the patch some may late than others where samsung needs to customize for different providers and telco.

The carriers-tied variants are getting M earlier than us. Something wrong man. I really want to know what drag them so long to bring it over here.

There's the problem: 1080p. I think 2K is too much for a phone and it puts extra strain on the phone for no reason except eye candy. The Mate 8 can be fluid and last longer because it only pushes a little more than half of the Note 5. If Samsung had kept to 1080p but bumped up the specs it would blow everyone else out of the water.

I wonder how you compare specs - just based on paper  ??

Chipset wise : mate 8 is much more powerful and just looking at its Antutu benchmark alone is more than 50% higher than Note5. In daily use Mate 8 is obviously very much faster and smoother than Note 5
Operating temperature : Mate 8 is very much cooler. One hardly feel warm even with intensive usage continously over 2-3 hours
Battery life : Mate 8 easily 10 hours SOT vs 5-6 hours most Note 5 users are getting
GSM/LTE lockup : mate 8 is top and doesn't faced issues such as calls drop off and LTE connectivity issues a common problem among Note 5 users
Display : mate 8 though only is 1080p, seriously I cannot see any significant difference with S7E, LG v10, Nexus 6P with higher resolution. Unless one has microscopic eyes only geeks will look for pixel differences. Anyway those who love SAmoled might not like the LCD display. Personally I just do not like Amoled as I find the colors being overly bright and colors too saturated. This I suggest you see it yourself to judge
Camera shots quality : can easily match Note 5 but loses out to the more superior LG V10, S7E

Note5 main advantage I would say is its SPen only
The Mate 5 is definitely positively a big upgrade over the Note 5
Sorry if I offend any Note 5 lovers/ users here - just speaking out based on my experiences having used both these phones

If you are happy with Note 5, why even bother to consider to change ? Change only if you wish a overall much better phone and you have a budget for it

Not only Spen but some others spec note 5 is better.after try mate 8 i can  say camera and display cannot match note 5
