[Note Edge Q&A, Help & Troubleshooting] iquit040:
I have both currently... And I am keeping...

I have been an android phone junky, flasher, and modder for years. I sold my note 3 and bought a nexus 6 (was on sprint). I then changed over to tmobile. Luckily the nexus 6 is factory unlocked (yes the Sprint model is). I used the nexus for 2 weeks and loved a lot about it. I picked up a T-mobile Note Edge yesterday. In the End I am going to sell my nexus and stick with my Note Edge:

Nexus 6:

Pros:

Truly unlocked and can be used with any carrier (Sprint, Verizon, Tmobile, ATT)

Beautiful 6 inch screen

Great front facing speakers (only phone that beat it was my htc m8... thats saying a lot)

Pure stock android OS with quickest update support

Extremely fast performance without slowdown with daily tasks even with tons of apps open

Battery Life (yes, even though the battery is non removable, it lasted me 1.5 - 2 days without recharging)

Turbo Charging - 15 mins gives 6 hours, this is actually true!

No Carrier bloat pre installed (also a con....)

Accessories: Like most phones can get decent cases and tempered glass screen protectors cheaply (although with the nexus you need to order most not much in stores currently)

Wireless charging: Built in support for QI wireless charging (helps makeup for the non removable battery)

Cons:

Signal strength ( some places I have had no issues with other devices, it struggled to hold signal)

Sound quality over some calls was full of static

No wifi calling yet

Non removable battery (i know I said that the battery life is amazing but still option to switch is great)

No sd card slot

Gaming performance disappointing ( Madden nfl has some noticeable slow down... doesn't make any sense with the specs of this phone and no extra bloat from another launcher interface)

Installing carrier apps gave mixed results, some worked but visual voicemail etc, gave problems

No extras : fingerprint reader, stylus, heart rate scanner etc ( i knew this ahead of time, but just saying in comparison with competing phones)

No one handed support (I usually have no issues with large phones even on the note 3/4 ,but did with the nexus). Samsung got it right with the shrinking down to make one handed easier.

Camera : Pictures overall are good, but the built in apps and the speed of camera to react left me disappointed.

Overall: If you want the biggest screen on the latest hardware, want constant up to date software, and no bloat the Nexus is great. It is truly what the "android" experience is meant to be without any adultery. The sound is great as well from the speakers for music and speakerphone conversation. Some disappointment with signal strength and sound on handset during calls but not deal breakers. Truly unlocked for any carrier, so take it to any network and not be tied down.

Note Edge:

Pros:

Amazing Screen (may not be as big as the nexus, but the picture and pop is better and noticeable side by side)

Call quality and signal strength are great. The noise canceling features make a huge difference for those on the other end and never had breakup or static on my end.

Interface and speed : Amazingly fast even with the touchwiz interface

Touchwiz : Yes I am saying this is a plus, Many things like messages coming across the edge screen, quick responses, and being able to send a text to a number that called straight from the history or dialer without adding them as a contact first is something you truly are grateful for once you move to a phone that doesn't have it. The quick are useful as well.

Edge Screen : I have found the tickers and shortcuts to be useful. Some of the features are gimicky but most overall are nice.

Extras: S-pen (great for creativity and productivity), fingerprint scanner, and heart rate scanner.

Camera: Front and back cameras are great and good built in editing options (pictures taping the heart rate scanner makes it a breeze)

Modding support: Samsung devices in general are booming with support for modifications (if you don't care as much about this, this means nothing lol)

Carrier support: Tmobile version is unlocked for ATT as well, this is a plus (not for all carriers like the nexus)

Gaming performance: Pointing out to Madden NFL that I noticed had performance issues on the nexus, runs smooth as silk, no slowdown whatsoever.

Removable battery : Easy swapping of spare

SD card slot: memory expansion and no worries if something happens to the device if you can still pull the card out.

Cons:

Software updates: No official Lollipop from samsung yet, should be out soon. Updates drag a bit with samsung and TW integration.

Accessories: Not many options for phone due to design and limited production. No tempered glass screen available yet (one coming soon supposedly). To me this is a decent concern, I have always counted on tempered glass to protect the screen and avoid scratches. Has saved my screen a couple times from drops. Replacing a screen protect for $15 bucks vs hundreds is huge.

Touchwiz: If you are anti bloat this could be a con, to me its not, but trying to fair to all.

Price: Even with contract extensions the price of the edge is crazy.

Speaker placement: While the speaker may be better than some of the past Samsung devices, the rear placements makes it a pain at times when listening to stuff on speaker.

Battery life: It isn't as good as what I saw on the nexus, doesn't come close to 1.5 -2 days on a charge.

Fast charging: is faster than past samsung devices, but nowhere near as fast as the nexus on turbo charging

Lack of built in wiress charging : At this price point , it is disappointing that this wasn't built in.

Overall: My favorite phone that I have owned so far. The modding support for me will be a huge factor as well. You are paying a hefty price with or without a contract to get it though. The lack of accessories is a bit worrying as well. User experience is very user friendly. Device is extremely fast and multitasks well even with Touch Wiz. Extras like finger print scanner , heart rate sensor and S-pen to me enhance the experience and productivity (heart rate sensor is trivial). One handed support and many things in the software show that it was thought out for user experience to make day to day life easier. Battery life is not what you can get from the nexus but you can carry spares. Addition of "fast charging" is good but not as good as the Nexus. The lack of built in wireless charging is a let down as well. Still the quality, features, and performance to me makes it a clear cut winner.
