Questions regarding the Note 4 - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello XDA!
I'm about to purchase a note 4 tomorrow from Wind mobile here in Canada. I would have preferred the nexus 6 but its just not available with wind as of yet.
So my questions regarding the note 4 are:
1) The Note 4 variant would be SM-N910W8, will it allow rooting?
2) Does Samsung allow unlocking the bootloader to install custom roms or is just a root sufficient to do that.
3) I've heard of something called knox, and how it will trigger once you root the note 4. Will this have any adverse effects on app functionality such as tap2pay etc..? I know the warranty will be void, but if something goes wrong with the device its a 50/50 chance of getting it repaired replaced.
4) My reason of preference for the N6 was stock android, is there a ROM currently that is AOSP based?
5) Is there a specific thread i can go to find roms for my variant?
5) Is there a way to return back to a virgin note 4 (unrooted, stock ROM)? And even when that is done, will knox still reflect the trigger as 0x1?
6) Lastly, i havent been much of a fan of samsung because i felt they were pushing out "cheap phones" And i must admit, ever since they came with the metal band with their alpha and note 4. Ive taken a great liking to them. So my question (I do only expect general replies) , How are you guys/girls liking your note 4 so far?
Thanks in advanced!
(P.S sorry if some of the questions are stupid, i researched and dug around as much as i can but couldnt find definitive answers)

Rooting restriction is carrier based. Some carriers lock down from rooting, others dont.
Knox is a one way trip. Once tripped it stays that way. It is effectively a fuse.
Had my N4 for two weeks and am loving it. Came from a rooted S4. Not really missing root that much. Wish I could still turn GPS on and off with Tasker and wish I had better access to the SD card. Not big deals though. There is another thread here about non-rooted solutions to many things people want root for.
Might become more an issue in a couple years if Samsung/Verizon fails to do timely updates.
Best advice to new N4 users is learn to use the S Pen. It is what makes the N4 stand out.

1. No it doesnt allow rooting. get a 910U - so far it seems the least hassle.
2. no rooting.
3. yes once you try to root your warranty is void. for all purposes assume you will never get root. then again, you dont need root. in fact having no root and knox is much better. you can have a dual personality phone which works very well.
4. irrelevant. if you get the note 4 expect to run factory.
5. no. you cant have root.
6. you need a full case to hold it. its a thin glass panel. ive got an iblason armorbox for it. also would recommend buying the wireless back and wireless chargers. cables are too much of a hassle on this phone.

My recommendation would be little biased towards Samsung given my last four phones were all galaxy. I never had to root Note 3 but I rooted Note 4 in few days of owning it. Google must have thought let's give some punch to Samsung by disabling write access to external SD giving excuse of security as Samsung is the only high end phone manufacturer that still has it. And one of the most used function that was very important to me was copying files off network share to SD which no longer worked. Only for this I rooted.
I buy Note series not for amoled or big screen or good battery life or running AOSPs. I buy for SPen. I snap, print screen, doodle and write catchy text and share, adds that special touch. And that Microsoft One Note supported inking in android, I am loving it even more.
Note 4

Thanks for the input guys, much appreciated!
While it seems most of you use the note 4 for its main purpose of being a multitasking phone. I on the other end just need the good camera, screen and battery. Everything else is gimmicks (for me atleast). However, this opinion of mine could be due to the fact that ive never owned a note before.
I did see some guides of being able to root the SM-N910W8 with CF auto root, as well as a way of bringing devices back to stock as i can see form this thread:
http://forum.xda-developers.com/note-4/general/ref-stock-firmware-kernel-modem-recovery-t2920452
Now, is that really the case or is there somehting im not seeing?

you can NEVER bring it back to stock. the efuse blows once you root. Do NOT root a note 4 until youre familiar enough with knox to make the choice

By stock i dont mean resetting the knox fuse. I mean, if I am on a cusotm rom, i can bring it back to stock for warranty purposes (which I know after the knox fuse is blown, is a hit and miss)
So my question still stands, will I be able to root my phone based on the thread i mentioned above and be able to return it to stock afterwards, or is there something im not seeing there.

I have a Note 4 with Bell so to answer your questions:
1) Yes. This is true for all Canadian carriers AFAIK.
2,4) Should be sufficient with just a root. I haven't been around for a week so I haven't caught up on new developments yet. I didn't see much in the way of AOSP last I looked.
3) This I can't answer but I know for example there is an XPosed module that will allow applications like GOOD to continue to work even with KNOX tripped/removed.
5) The W8 is similar to the 910T. I'm actually running DynamicKat with the KTNote4 Kernel. When you install DK part of the install script checks if your phone is a 910T or a 910W8 and installs the correct kernel. I had an issue with my initial flash of it bootlooping but I used the Stockish kernel from twistedumbrella that I had flashed when I still running stock rooted and backed up the boot image so I restored that boot image and it booted, then I flashed KTNote4 myself. Check here http://forum.xda-developers.com/note-4-tmobile/development and here http://forum.xda-developers.com/note-4-tmobile/orig-development for roms/kernels.
6) Yes you can just flash a stock rom (should be floating around somewhere) but Knox will still be tripped.
7) Overall I'm absolutely loving it. I came from an S3 that I was running CM11 on with KT's kernel (seriously, his kernels are amazing!) and I liked it for a really long time but it started to get really sluggish and it just can't handle multitasking the way I'd like it. I do still notice slow downs, and the phone does still get pretty hot sometimes, but that's the price you pay for multi-tasking. KTs kernel certainly isn't perfected (granted I'm on a build from 2 weeks ago) and sometimes it will randomly reboot and bootloop at the splash screen but once I clear cache it boots right up. Usually only does this once it's been pretty hot for a while. I love the multitasking windows, that's exactly what I want. The one thing that threw me off the most was the DPI. It's a big phone, I don't need everything on it to be gigantic. So I did end up using the XPosed module App Settings to scale the DPI down to 480 from 640. There are a couple quirks when doing that, like the task switcher is smaller (since it was designed for 640 DPI) and there are a couple apps that you have to set back to 640 as well like the camera but you can always fix those as you find them.
I'm a firm believer that Android is a dev's playground. I could not use this phone happily without root. In fact, I rooted it the same night I got it within a couple hours. I bought the phone outright since I would have had to change my plan if I wanted to early upgrade and my plan is too good to do that. Happy modding!

Just use Autoinput. Can trigger GPS.

Why I am planning to NOT root my awesome Note 3

I used to root all my devices, my S2, my note 2, but not my note 3, and here's why.
1. I used to hate TouchWiz, but now with all the new features like air gestures, S pen features, smart stay, IR blaster, etc, and the updated more "Realistic" look to it, i will have no need to switch to AOSP, even if it is smoother, i have 3gb RAM anyways (Oh GOD do I LOVE the 3gb of ram!!)
2. Dam KNOX!! Y U DO DIS!! Y U VOID MY WARRANTY!?
3. I own a Rogers note 3, and a mac. No way to root it yet with a rogers note 3 and a mac
4. I will lose features if i switch to AOSP, and if i switch to another TW custom ROM it would most likely have some bugs that the stock one doesn't have.
5. DAT CAMERA.
6. Bricked phone once, softbricked a couple of times, and let me tell you, first time i bricked, i couldn't sleep for 2 whole nights. And always paranoid when rebooting phone that a bootloop would happen or something.
7. No need to overclock or change kernel, i am more than happy with my high-end device right now thank you very much.
8. Worry-free!!! I will never have to worry again!! Sometimes i think to myself why i always root my phone and mess something up, and always have to heimdall back to stock.
9. I own a GALAXY GEAR!! Switching roms may risk making my gear UN-USABLE!! Which SUCKS!! paid 300+ bucks for this thing!!!
10. I am plenty happy with my phone and don't plan to mess it up anytime soon. I love my stock Note 3, and my Galaxy gear too

Agreed...i mean half the stuff he mentions has no bearing on root whatsoever...and to keep
Knox when we don't even have the option to run the encrypted dual boot partition makes no sense. Plus i also have a gear, and its also rooted...i take it he either has never rooted or has no clue what rooting actually does. He mistakes romming with rooting, and makes it seem like rooting is somehow capable of breaking functions like bluetooth???
Not trying to be a jerk, but posting this list is irresponsible and counter to the foundation xda is built upon. Your basically posting this as a justification for not rooting, but why, why not just not root...what's the point of this post at all?
Many noobs or first time rooters will see this and be confused thinking your mistakes and errors that caused the brick, or mixing up root and rom are the norm or cause for concern, and neither are true.
strait up...root does nothing more than "root" level access, or basically full access to your device aallow in you the OPTION to remove apps or customize your device. It in no way breaks bluetooth, or affects your launcher (touchwiz) as is being alluded to.
Mega
This phone is pretty damn powerful even with a ton of bloatwares running in the background. I can see that this might be the reason why some don't feel the need to root and modify their note 3. But if you say avoiding root because you want to keep your phone perfectly functional, then I don't understand the reasoning here. Root doesn't render the phone useless, it is what you do after you root it that bricks or damages it. You can root this phone and keep all the S functions you want, add more stuffs to it and the phone will still be perfectly functioning, but of course it is a personal thing.
I personally rooted this phone, modified a lot of things before I even put the new sim card in and activated it. This phone is pretty powerful by stock, but I like to mess with it, and I usually read up a lot of posts before I do anything crazy, and I always have odin next to me when I do it. So far nothing is damaged and the phone is running xnote with all the S functions running smoothly.

You will change your mind
If for nothing else then just to remove all the bloat. After I removed all the bloat my ram usage has been around 1gb out 2.xx gb. And my battery life has been GREAT. I get 7 hours+ with about 24+ standby.
Here is my script http://forum.xda-developers.com/showthread.php?t=2587899 (if you change your mind
I've been doing this since finding rsd lite was like warez and you had to do hex edits, and rooted day one. I think my phone is more functional and has enough customization to make it as individual as I am. It's your choice to root or not, but I agree with the post above you might give the newer members the wrong idea.
Not sure what value this thread has now that it has been said...nor what it has towards development.

(Soon to be) New TMO G2 owner

Just have a few questions and concerns about moving to this phone, figured I'd give it a shot and see what the collective group thought...
Background: Coming from a GS3 (T999L LTE model) and avid hater of KNOX and stupid warranty bit tripping issues, lock outs and general d*cking around the device manufacturer does to the device to make tinkering next to impossible. I understand there is a similar situation with the G2, and also understand there *might* be ways to work around it?
1. Seeing as the new OTA has gone live for the G2 on Tmo, how likely is it that I'll receive a new unit with the update on it?
1a. If I get one without the latest update, how easy is it to then root/custom recovery/update retaining all of those​2. I'm perfectly cool using the stock ROM, I mostly just root for debloating and ad-blocking (I love supporting devs, some don't have ad-less options though). How much bloat might I encounter and are they easily disabled (without need for root).
3. Are there any goofy folder setups in the internal SD card? (meaning on the GS3, once you went to 4.3 it changed the layout to /sdcard/0/DCIM versus the original /sdcard/DCIM)
4. I've grown very accustomed to using the volume rocker to change tracks when I'm in the car, so I don't have to look down for the next arrow...Is this an option that is baked in or will I need to use Xposed?
4a. Is Xposed working on the latest official ROM? I've seen people having it working and others saying it doesnt​5. I really want a wallet style case for my device, nothing special, maybe 2 slots to carry a burner debit card (I'm notorious for forgetting my wallet and want to carry a card with my phone since I never forget it). What would you recommend? I've seen the Poetic Flipbook (http://goo.gl/eGf0XL) and feel like it would be a good fit for what I'm looking for...Thoughts?
Thanks for your time, can't wait to jump ship to the G2!

well lets begin-
1)about it coming wit the update I would not know I'd say 50/50 chance(if it's on the latest 4.4.2 it is not rootable you would have to flash back to 4.2.2 using this thread http://forum.xda-developers.com/showthread.php?t=2432476 then follow this http://forum.xda-developers.com/showthread.php?t=2673736 to get to kit kat with root and custom recovery)
2)yes each variant has it's amount of bloat but some are worse than others and it can be easily be removed except for the ciq which can be disabled on 4.2.2 but on kk it's giving issues
3)yes it is sdcard/0/dcim
4)I grew used to that feature two but I have not looked for a replacement but iknow g2 exposed has that option but until xposed framework gets updated to 2.5 it will not work on kitkat but works without issues on 4.2.2
5)as for case I use spigen so I don't have any recommendations but check out the g2 accessories thread and you can find help there and look through the stuf that has been reviewed already
yea it's an awesome phone
To be honest the g2 is and awesome device but the nexus 5 comes with no bloat and is stock android out of the box g2 is a great device but get its more bugfree twin nexus 5 is prob around the same price as the g2 and your going to T-Mobile I would go with nexus 5

Is Galaxy S6 worth rooting?

Hi guys!
I'm writing this thread to anyone who is considering rooting his own S6. Well I wasn't sure for 5 month because I was afraid of losing my warranty. Like 3 days ago I decided to end with bloatware. This was one of the best thing I did in my life with my phone. Flashed XtreStoLite and custom kernel (arter97) and this device is now crazy fast... Damn I didn't expect these results. Also my battery is now much improved than it was before.
I know it's XDA forum, but maybe there are people like me, who are still waiting to root their phones. This thread will help them to take their decision.
Also you guys with rooted phones - write your feelings when you did it.
I've always rooted my phones and used custom ROMs, but I've become more and more reliant on my mobile banking apps recently. As they don't work on rooted phones, my S6 is staying unrooted.
Is Samsung Pay the only function you lose when rooting and/or installing a custom TW ROM?

Hmmm... In my country Samsung pay is not available yet. So I don't care about this one. Also I don't know about any other disadvantages of root or custom ROM.

You also lose Knox, warranty (depending upon your country) and OTAs.
I've always rooted my phones starting back when the galaxy s fascinate came out, been on this forum a long time and rooted lots of tabs and phones thru here. You can always flash back to stock if you don't like root.
I actually rooted my Nexus 5 but don't feel the need to root my S6. The only thing i used it was to change the dpi on nexus but with the screen grid option i don't even need to on S6. Phone is working perfectly fine and unrooted gives me peace of mind of safety and OTA updates.
Since Adblock Fast is available for M6.0.1, I don't need to root my SGS6. Web advertisements and banners was main reason for rooting my phone, because i was using Adaway, which is "root only" app. Adblock Fast is working like Adaway (except adcvertisements in free apps, of course - i don´t mind of that, I'm willing to pay for good app) and without root. Yes, with root I can have more functionality (exposed framework, tweaking stock apps, ...), but I can live without that. And I'm happy that my Knox is not tripped and have automatic OTAs.
I'm incredibly glad I didn't jump straight into rooting mine... The camera started to occasionally play up after a month, sometimes making a noise when focusing. This progressed over the months to becoming more frequent, and sometimes I'd have to literally shake the phone to get it to focus.
Two months in I handed it in but they couldn't find anything wrong with it. Five months in it was so bad that they couldn't deny it and repaired it there and then when I read the newspaper with a coffee (kudos to Samsung: only some stores offer that service).
So yeah, I wouldn't root my phone again within six months for that reason.
I'll still root it though - I'm just waiting for official TWRP compatibility at the moment.
As a side note, I asked the guy who handed my phone back if they check KNOX routinely. He told me yes for software issues, and occasionally for hardware issues (especially for screen issues). He didn't bother checking mine apparently.

Rootcloak fixes this.
I rooted mine mainly for adaway and xposed, but I have to say that not getting OTA is annoying - however Samsung is too slow with the updates that I don't care anymore (still no marshmallow in my country).
I had problems with mine I was on 5.1.1 rooted updated to marshmallow my phone came up with emergency calls only back on 5.1.1 after repair funny thing is the repair shop rooted my phone to make sim work again weird
Hi guys (and gals)
I've always rooted my phones because I wanted to have more powerful, flexible device. I did this with my old HTC Wildfire, HTC Desire HD and Nexus 4 but with S6 I don't feel I need this anymore. The device is just as good as-it-is – without root, Xposed, mods and so on. And 6.0.1 update gave it new shine and powers. Of course it's my personal opinion only but I must repeat – Galaxy S6 is the first Android phone I'm pleased to use without any modifications (maybe except for Nova Laucher ).
Have a great day!
I am happier with my marshmallow now that it's 6.0.1 rooted with xposed mods to tweak with it. I'll always root if I can just because I can't stand not messing with it, lol.

I got Marshmallow 6.0.1 about 2-3 weeks ago, and I've had two minor updates (around 13-15Mb each) since then. Can't fault Samsung in my country.

Is losing the warranty worth rooting? Is it ever not a good choice?

I have been rooting my phone ever since my first Android years ago (HTC Incredible). I'm not too wild with the customizations, basically root it to make minor GUI changes, overclock at times just out of mere curiosity and boredom for when I want to have fun, and to remove the bloatware. So basically, I never really have used a custom ROM. Whether it was the Note 4 with the one click root app, or using a program on my PC with the original rom for the LG G2.
My question though... Is there much to worry about when I trigger Knox in my S7 edge and lose warranty? I pay for Asurion insurance* (yes, it's overpriced but it's a luxury I like to retain) but would there be a scenario where having a valid warranty would be beneficial? I remember back years ago there were times when my phone broke and I got a brand new phone through warranty* (avoiding insurance - which means not having to pay a deductible).
Is what I use root for worth the loss of warranty?
Thank you for your time guys!
One aspect to keep in mind is Samsung pay. From what I understand, Samsung Pay will not work once Knox is tripped. This mat not matter to you if you dont care to use Pay, but it may affect resale of the phone if someone interested did want Pay. Thats a negative I can think of. Just my 2 cents.

We can't tell. That's your own decision. We don't know your financial situation, we don't know how you would benefit from a rooted device. So; If you can afford to repair the device with your own money + if you'd benefit a lot from rooting it, go ahead. If both scenarios are not applicable to you, the don't.
I've always rooted my phones except this last one because there was no root. But after using it as is for 1/2 year I'm actually ok with it. Samsung pay and a couple of other things that never worked on rooted devices work ok. I already used the warranty once so that's good. And my main reason for rooting it was adaway and titanium backup. But now there are a few apps that block ads in the browser and don't require root. And they work ok for the most part. Lack of backup is not great but I learned to work around this using samsung and google. And only needed to use it once when changed the phone. Otherwise I am enjoying it. It updates itself while not loosing any data, everything works, warranty is there and I don't get too many ads. I hardly have 1-2 apps that give me ads and that I use maybe once a month so that doesn't bother me anymore.
Its a personal choice... I dont use custom roms mainly because they dont work, the only one I used was a a stock rom for the note 4 that was deodexed, the rest of the roms alwas have some sort of problem, cam doesnt work, led doesnt work, battery drain, crashes, etc, etc, etc, just read every rom thread, no one is fully working.
I rooted the phone to make the battery last longer. Some days ago I unrooted the phone to play pokemon go with my kid and android poped up an alert notifying that my device was slow... and ofcourse iit was slow because of the stupid apps that im not using that are running in background alone.
Going back to the early years of Android, there were many compelling reasons to root your device.
As time has passed, the "stock" experience has got better and better, and the number of reasons to root has definitely got smaller.
Personally, I've not rooted any of my devices since the Note 3, and I've had many since then.
I know some people like to root as soon as a device leaves the box, but my advice these days is to use a device stock for a period before making any decisions on rooting.

Dave

All things root and Bootloader?

Hi Friends,
Hope you're all having a great new year. So last time I was lurking the S7E forums, we had a leaked Engineering Bootloader that was used to acquire root on all US Snapdragon models, albeit, with a lot performance issues and etc.
I came here to glance as well as all other variant forums for the SD model and now we have Root for every model, with even ROMs being baked like the Echo ROM for Verizon, Sprint, AT&T models, usually the toughest to achieve these things on. I'm trying to read through the forums, but I fear I'm missing the details, that will help me pull the trigger for getting the device or not.
Can one of you very experienced, knowledgeable, and kind members educate me on the latest?
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
4. Xposed Framework working for all models?
Much appreciate your responses, any and all of them in advance! Thanks!

Absolutely nothing has changed on root (only possible due to ENG kernel) and bootloader unlock (which is not yet possible).
1. No
2. No
3. No
4. No idea about all models. For the t-mobile one, please check: https://forum.xda-developers.com/tmobile-s7-edge/how-to/guide-installing-xposed-framework-t3414718
You can use the search feature in xda for finding out

Hey bud, thanks for getting the ball rolling on these questions. If you could add some more information, I'd appreciate it :
If we still don't have a way to Root or Unlock bootloader, how are these ROMs (Echo, Tek, and other stock ROMs) available with root? And how are these flashed? Are we somehow bypassing the BL by using FlashFire?
Can you also educate me on the U Firmware and why people install it and is it reverseable?
Lastly, if I got a T-Mobile variant for example, installed these ROMs Tek, Echo, etc, can I return to Stock completely and return to T-Mobile, by any chance for them to take it back? Thank you again!
for the t mobile variant, I was able to flash the U firmware and flash back to stock t mobile. NOTE: I did not flash the U bootloader. I kept the T mobile bootloader just be sure I could flash back to stock t mobile(APK1). I'm sure this method would work with other carriers as well. so what ever variant you have, make sure you stay on that BL and only flash the U firmware CSC and AP. As for the CP(modem) I would flash your carriers latest CP file. That's what worked best for me with the U firmware. Currently I'm using the latest nougat BETA
Thank you very much for your response, bud. One last follow up question: Since all the US variants are rooting based on the ENG Kernel, is there really a benefit of getting one variant over another, for rooting or etc purposes?
P. S. May I ask why you flashed the U Firmware? What are the advantages of it? ?

The u firmware basically does not include all of the software that is usually included with the phone. For example.. Tmobile with their software on it, Verizon att etc... Makes the phone a bit snappier especially if you were to root. Even tho I hope for a more stable root still. I am rooted at the moment. Wish they didn't recall the note 7 because the root on that was better

You're confused. At least, you were.
We do not have an "unlocked Bootloader" and we never did. We had an engineering kernel. That engineering kernel allows certain commands that enabled us to acquire root access. But without that kernel, the system (with the original kernel or boot partition) checks for any changes in the /system partition. If any are found it triggers a bootloop. So basically, if you want root we MUST have the engineering kernel. Unless someone else finds another way that's just the way that it is.
Personally, I unrooted and went back to stock. Root was okay at first but with the lack of development, Samsung Pay and the fact that Android 7+ will probably not be seeing root... well... time to accept the fact that Samsung owns the phone even though we bought it. What else can we do?

Thanks for your helpful responses fellas. I understand root is not perfect, but for some folks like me, Xposed seems to be worth the trouble. For Samsung Pay, I intend to use the Gear S3 one day ?.
Final question, since all US Snapdragon models are using the engineering kernel to root and etc... Is there a benefit of getting one carrier variant, over another? For example, Verizon is usually the cheapest. Is it wise to get that, with the U Firmware, to use on AT&T? Thanks!

Let me know if that works out for you then.
I just purchased the S2 Classic (on T-Mobile) and use Samsung Pay quite a bit. But I can tell you that it does open Samsung Pay on the phone and if you are rooted, Samsung Pay will not work at all. So I'm not sure if it will work at all for you even with the S3.
In regards to your other inquiry, I haven't tried the U firmware. I read something about data issues, no wifi calling (which is pretty important to me), no hotspot (which is also really important to me) but I heard that it is really fast. Not sure how much of that is still a problem but you should probably read up on it before doing anything first. But the rooting method is all the same between carriers I believe. All require the engineering kernel and breaks Samsung Pay along with a couple of other apps.
Just make back ups, have a stock firmware available to flash with ODIN just in case and remember that it's almost impossible to brick this device (because we don't have an unlocked bootloader.)

Thank you again for a helpful post. So the S3 has a dedicated MST/NFC chip in it, that allows for Samsung Pay to work from the watch, it's done through the Gear app. That's what I have read.
About the rest of it, again, curious to see if there is one US variant, superior to another in terms of Root capabilities or bands and radios available and etc? Can anyone confirm this for me?
Thanks!

So does the S2.
When I was setting up the Samsung Pay on my watch it said that it had to download an update.
Then I went through the setup process through my phone which was from the Samsung Pay app.
You go to "Add card" on your watch and it opens Samsung Pay on your phone.
You click "Next" and it displays your Samsung account information.
Then it takes you to a screen that says "Setup complete" telling you that you're ready to use it and at the bottom says "Add card"
You do that all from the Samsung Pay app on your phone which leads me to suspect that if you root your phone, you won't be able to use Samsung Pay on your watch.
People on this thread that you have to set it all up first, remove the Samsung Pay app on the phone but leave it on the watch. If it's all done correctly then it should work. Just make sure you get it all set up first.
Next thing that I'm going to try is using my watch in "Standalone" with my phone out of bluetooth or wifi range. See if that still works.

As far as I know, the U firmware permits use of some other bands that aren't normally used. Not sure which ones though.

Thanks for the correction/education on the S2, bud, much appreciated. I wonder if the rooted phone works with the S3, because Samsung has allowed many other non Samsung phones to know work with the S3? But I could be wrong, I thought it was open like that with the S2 as well, no? Looking forward to your testing, hope there is a breakthrough in there! ?
if you want root and customizability and roms, just don't get this phone. you will be very disappointed with the performance once you root and it gets so much worse with Xposed. not worth it at all, you will have better performance and speed from a 4 year old phone that has an unlocked bootloader and strong development. I mean my Nexus 5 (from 2012) had better performance than my rooted S7. it sounds like you do want roms, and if you want roms then AOSP/Cyanogenmod is the way to go. there will probably never be any AOSP or CM ROM on the QC S7/E so you're better off getting an older galaxy model that does have a great development community and unlocked bootloader. or just get a OnePlus or Nexus or something.

exactly this. except for some reason I thought exynos variants are lacking certain bands/features on American networks. could be wrong.

Very helpful inputs guys, thank you! If I were to be honest with myself, I don't want AOSP/CM/Lineage, especially on a Samsung phone, so unlocked bootloader is not a deal breaker for me. However, I think root is cool for me for doing some SystemUI tweaks, Xposed and etc. Exynos was an option I was exploring, but lack of warranty, no Samsung Pay, and the price are enough to keep me at bay. I think I just need to put my big boy pants on and try to use a phone without rooting it. Something I have yet to do in EVER using an Android phone since about 10 years ago, and I have never ever used or bought an iCrap... I mean... an iPhone !

Get a One+ 3T good development and really nice phone if you want root. Root is dead on Samsung phones and so are ROMs.
So by reading thru this thread, I assume having a T-mobile S7E (G935T) rooting is pointless and really not available the way I'm used to it coming from a Note 4. That's kind of a bummer... I've been using Android and have always had ROOT and all the goodies that come with it. And I recently starting really enjoying my Note 4 with all the cool development in Note 7 ported roms oh well... I wonder if the S7E is enough of an upgrade to keep my interest as stock?
I see there is a G935U firmware, but that seems a bit hit and miss? But I'm just starting to read up on all this... :good:

You and I both man... The last few years, I have lived off the mercy of T-Mobile and their BLs being unlocked. But Samsung sure done them all in ! Even the International unlocked ones disable Samsung Pay (forever, mind you!) if Knox is tripped, which I believe it is, when rooted and TWRP'd.
As I understand it,
Android pay / Samsung pay is why they frown on rooting now. I can understand it, though I don't agree with it.
The first time someone's financial information is compromised, and they've ever used one of the "pay" methods, on a rooted device the pr nightmare that would ensue would make the note 7 fiasco look like child's play.
"Samsung unsecured device compromises persons credit card information today, while Apple is still secure" I can see the headline.
