WiFi Performance
While the Galaxy S5 LTE-A Broadband had a Qualcomm Atheros solution (QCA6174), the Note 4 moves back to Broadcom's WiFi solution. In this case, we see the BCM4358, which is a revision of the BCM4354 that was first seen with Samsung's Galaxy S5. This shouldn't have any major differences outside of improved Bluetooth coexistence but antenna design can and does change between revisions. In order to test this, we use iperf and Asus' RT-AC68U router to try and achieve maximum performance.
As one can see, the Galaxy Note 4 has a strong showing in this test, easily surpassing every other device we have available for testing.
GNSS
At this point, it really goes without saying that the GNSS solution of choice is the one built into Qualcomm's modem. This allows for fixes based upon initial location and time data that the modem has, and therefore in practice every GPS fix is a hot fix and takes around 5 seconds for a lock in good conditions. In the case of the Note 4, with airplane mode on and no assistance data I saw that it took around 50 seconds to achieve a lock, but this is strongly dependent upon environmental conditions. Once locked, I found that the Note 4 had quite a strong lock and quickly went down to 10 foot accuracy level without issue.
Misc
Similar to the new Moto X we see a Cypress CapSense solution in the Note 4 but this is likely used for the capacitive buttons rather than any impedance-matching antenna tuner. The UV sensor appears to be a Maxim design win, although there's no information on the specific part. The battery's fuel gauge is also a Maxim part, as is the speaker amplifier and pulse sensor. The NFC chip used is NXP's PN547, so host card emulation should be supported and therefore Google Wallet's tap and pay system should work as well.

It looks like they focused on the design and the display this time. I like the trend away from over saturated displays.mkozakewich - Wednesday, October 15, 2014 - link
No, they used movie mode. I didn't catch if they went there from where they were.Really, though, a larger gamut is a strength. All we need is for OEMs to create profiles so that we don't have the weird problems we had. They can create an sRGB profile, and an AdobeRGB profile, too. Then, when Android finally supports proper colour systems, they'll be able to introduce that immediately.

Disappointed that this isn't waterproof like the Galaxy S5 and S5 Active. I'd get the S5 just because of that.Samus - Wednesday, October 15, 2014 - link
Waterproof phones have never proven a big hit with consumers. The Kyocera Hydro and Galaxy S5 have a lot of inconvenient plugs and gaskets, with harder to press buttons. Then there is the added weight of the Active. There is always an Achilles heel to mil spec implementation.But it's good consumers have the option of waterproof devices, I just don't think the Note 4 being waterproof would be a compelling feature. I mean, if you drop the thing in the urinal its so big chances are the toilet cake would prop it up...and it's probably not on every sailors list of devices to have something so big.

There's also the fact that it's not very important to most people, if you'll be by water on a boat or something a $10 bag/case will do. Or hell, even a ziplock bag really. If it's a major concern for you then you're probably willing to spend the $100 on micro-sealing.petar_b - Wednesday, October 15, 2014 - link
I see waterproof feature it more like investment into protecting the investment rather than a feature. I would pay $100 on micro-sealing - just to be sure: if I am walking on the rain (following GPS), or phone accidentally falls in a puddle, or my kid accidentally drops it in the bath that it would survive. And protection bags are ugly, can't go on meeting with that, can't put on/off all the time. Additional frames to protect the screen or side sealing do reduce GPS signal; so no after market solutions.darkich - Wednesday, October 15, 2014 - link
I think the lack of water resistance is actually the result of the stylus slot. I could be wrong, but it seems somewhat logical that waterproofing such design would be difficultTams80 - Thursday, October 16, 2014 - link
I don't think so, unless the plastic of the stylus slot couldn't be impermeable (something to do with thickness?). It uses Wacom Penabled technology, so it should be possible (the Fujitsu Q584 has some water resistance with such a AD stylus).darkich - Wednesday, October 15, 2014 - link

Disappointing really, not much wow factor here even if the materials have improved it just looks like a large Galaxy 5 with even less items of interest. Guess I will stay with the iPhone 6 plus.
