I have huge LTE issues. The coverage where I live is amazing, but my phone will not prefer LTE no matter what I do. Does the phone software just suck or is there something I can do?
LTE only - works, but then I cannot make or receive calls. All other modes will prefer 5.9 bars of 3G over 5.8 bars of LTE. Which doesn't make any sense.
Btw I am on CloudyPro II but I don't think it is a ROM issue because I never had had the phone prefer LTE even though I have almost max LTE everywhere.
I have also tried with fast dormancy enabled and disabled. It makes no difference.
Is there a way to make this phone prefer LTE?
Same problem here. Even though i got 4g on my place, it will connect on edge or 3g. Sometimes i got no signal at all. I dont have thos problem on JB. Im on rooted stock KK international. Is this a kernel or baseband issue?

Hmmm... I had the same problem on JB stock...
Another thing that I noticed is that if I for instance set this phone to LTE/GSM/WCDMA it will go nuts. Sometimes changing between H and 3G almost every second. Just back and forth.
It is almost as if this phone will poll the network several times each second and then prefer the strongest signal while completely disregarding data speed.
First, why are creating new threads when already exist similar topics? Do you read old topics? Maybe it has contained answer

And what could it possibly do? You prefer it to connect to some 5miles fay away LTE cell only if it's speed is faster but your modem will then constantly drop packet and reestablish connection to drain the battery? Or should phone grab a nearest and most powerful signal from 3G cell?
And third, wait for Kitkat, it contains a newer 190084 baseband, maybe it will relieve your pains
Then again, why do you complain here instead of going straight to you operator office? It surely is their fault to tweak their cell wrongfully. We can't change their settings

I have tried with different basebands and in case you didn't read my first post I have full LTE signal (6 of 6 bars) if I force it to pick LTE only. If I don't, it will pick 6 Bars H/3G.
I have also tried many different ROMs and I have checked the settings of the Sim card. It is set to prefer LTE.
Btw, did you read the last post in the thread that you linked to?
With LTE i get a ping of 34 ms and 15/5 Mbps. But the phone will pick a HSDPA connection with 47 ms ping and 6/1 Mbps.
And I am on the stock KitKat baseband but like I said I had the same issue on JB
If I force it in my office downtown I get up to 70 Mbps. And as soon as I switch back to default settings (if I boot) I go back to good old HSDPA if the phone is in a good mood. Otherwise I get 3G.

I have the same issue, I don't get why WCDMA preferred exists and not an LTE preferred (in *#*#4636#*#*). I'm running stock everything, only thing I've done is rooted, and I'm updated to the lastest firmware with Knockcode that T-Mobile pushed out.
Best way to discribe it is the phone gets "stuck" on whatever band it falls on. If my LTE is weak, it will fall back on 3G or 2G and just stay there - it seems like networks aren't prioritized. The phone should (in a perfect world) look for 1) LTE, 2) WCDMA, and then 3) GSM in that order and only pass one over if weak or doesn't exist, and should it pick up a higher ranked connection it should switch back. It seems the LG G2's just don't... If it falls back on 2G it's perfectly happy staying there until force it back to something else (default mode LTE/GSM/WCDMA) and it's rather annoying. LTE only is viable only when T-Mobile enables VoLTE on the G2's, but as of right now it stops all calls from happening, and I can't even change my phone to only use LTE/WCDMA, because where I work we just got a tower upgrade to LTE and they took the 3G offline, so calls still won't go through since it has to fall back to 2G.
I'll give Samsung some credit when I had my S3 and S4 on AT&T they would always follow the pecking order of what I stated above (in a perfect world) and I never had an issue, but the G2 blows the S4 out the water in performance in my opinion.
Hey guys just wondering if there are any exynos users who have T-Mobile in the USA (Atlanta for me). Im using the n910U and i get a 4G signal pretty much everywhere but out of nowhere it will drop to 1 bar, and then drop signal all together. Its getting quite annoying as it was said that the unlocked version was supposed to work with T-Mobiles LTE bands. It also happens when using the download booster which is also a pain. Any suggestions on improving the signal? thanks in advance.
Bump. Anyone have any advice to remedy this?
Im planning on buying the sm-n910u aswell but I want to use it with metro pcs which should be using the same network as tmobile, I dunno if ur problem is the phone or network hiccups but im hoping it will work here in nyc

A few things to look at
Try 3g only awhile, you may have a marginal 4g signal and the phone keeps switching back and forth
Try to find out which bands are coming off each tower in your area as well as tower location
You are one of the first to use the new intel modem in the usa for this phone
Keep us posted
Back in the HSPA days I had nothing but international devices and frequently experienced what you described. All the carriers have different networking h/w and topology because they all grew through acquisitions. If I left my home town where I had decent coverage when my flight would land in another region I'd have to reboot my phone to get it to connect to the network. When doing speed tests with friends using "real" AT&T phones their phones were always faster and more reliable. It was only an issue less than 10% of the time so it wasn't a big deal (to me). For better or worse the carrier's optimize the radios in their phone for their specific networks. So, at least in theory, a carrier phone (used on the carrier that provided it) is always going to deliver the best performance.
I got my N910U from Hong Kong, and my 4G signal is as weak as hell, though i'm a China Unicom user.
My iPhone 5s has much better signal than it, same SIM same network.:crying:
There must be something very wrong with the Exynos version of Note 4.
Hope Samsung could fix this ASAP.
Yea it happens pretty randomly in my house and when i leave to drive around town. The signal will be 4 bars on 4G then suddenly just drop connection all together for about 10 seconds. its a real drain on the battery when it does it so often. Im wondering if its a software issue with the radio in the n910u? Since we have root already we can load a different radio on it and see if it improves?
Got the same thing going on with my 910U on Fido Network in Canada. I must note it seems like it doesn't affect performance except for a network speed, no issues during the calls but 4G signal is at 1 bar most of the time unless I'm outside in downtown or something. I must note 3G signal was almost always at full strength. Not sure what is going on here but I thing we really could use some modem update here lol

I also have hongkong N910U model and facing signal issue on regular basis. When Problem appear I can not receive calls anymore and when try to make call , signal disappear altogether. After I retry a couple of times then it works fine but only solution is a restart to get the full strength. it feels like it is a software issue rather hardware but still keeping my device in observation. I feel when I enable power save mode only after that this problem appears. trying not to enable power save mode and test the issue for few days.
Kindly also share your own experiences to solve this issue temporarily.

If have exactly the same issue !!!!
Start with full signal strength and going down to the lowest strength and minutes later no signal !!!
Reboot or Airplane mode can undo this, but the cycle starts allover: Full strength, less strength and no signal.
Tried with 3 different carriers !!
And 2 Note 4's !!
I have the Snapdragon version SM-N910F

Swapped the note 4 again.
The third one and a new simcard fixed the issue !!
3 to 4 bars signal strength/
I have this problem since yesterday, it seem like the Note 4 is dropping the Sim card. In panama we have a provider that will need to register the sim card with names and stuff but i never did and every time i turn off the phone it will pop out that menu from the sim card.
Yesterday it was popping out every 20mins so i assume that the note 4 is dropping the Sim card. i didn't have that problem when i started using it. its been only a week and this problem came out. I got no signal, with the circle and a dash to full signal and drop signal back... all day, I can't even play online or watch youtube or other things. But it work fine with wifi!
I changed providers no more issues for me. Gonna change back next week and a new simcard also
I am in Colombia and my phone always is with one bar of signal, but when I am making or receiving a call it get full bars of signal. Do your phone do that? (I have the N910U)

Have this device on Bell in Canada. Not having these issues at all, but haven't rooted.
So I bought my wife what I thought was a good deal and got her the N910H not knowing that it was 3G only. Ok, well, on her verizon branded unlocked note 2 she can get HSPA speeds with her sim, but with the note 4 that's unlocked, she hasn't seen above the edge network, and her signal is garbage. APN settings are what they should be, tried a few different variations, and nothing. Bought a Verizon 4G LTE sim from straight talk for her, before I realized it was 3G only and only assumed it would help. But would it help? Both ATT and Verizon get LTE coverage in the area, or what can I do to fix my signal? Oh yeah, and I can't send or receive pictures...ugh. HELP
*apparently she can now receive pictures, but still can't send them

Try changing the modem, i should help, cheers:fingers-crossed:
I almost purchased the 910H myself but luckily found out it doesn't support LTE before pulling the trigger. If you can still return it, get the 910C model instead. It supports LTE for both AT&T & T-Mobile.
I'm using my 910C on Straight Talk AT&T ATM.

So, just tried the only 2 other modems I could find for my N910H running KitKat, and signal is no different. Any more ideas?
update
Ok, so playing around with some of the settings in more networks, mobile networks I changed the network mode from gsm only to wcdma/gsm (auto connect) and data speeds are NOW where they should be, which is 3G, and with a full signal got 8MB down speed, so, that's good. Now the question becomes why can i receive pictures and not send them. Actually managed to get a couple to go through, but no clue how or why they went through.
After activating my 6p on AT&T I noticed slow LTE speeds compared to my Nexus 5 (not just speed tests, actual browsing/usage). Contacted AT&T support to verify IMEI and SIM information and they did some sort of SIM refresh on their end. After that I was getting around 70-80mbps speed tests for a few days but now the speeds have dropped back down to 5-10mbs (if that).
I've tried switching to PHONE and PTA APN's and no difference is observed. I am not on an unlimited plan so no throttling should be taking place.
My friend who is also using a 6p on AT&T is seeing the exact same behavior and had the exact same results after contacting support (fast speeds after refresh but slows down after a few days).
Has anyone else been experiencing this issue with AT&T or any other carriers? I'm not sure if this is a radio firmware problem worth reporting to Google or something on AT&T's side.
I'm having this same problem, my s4 was at least double the LTE speed of my 6P, I've been searching for a fix but this thread is the only one I've found so far, I did see VZW post where you can dial a certain number and select bands, I'm hoping someone can share a fix life that for us on AT&T
same here ... very slow compared to all the other phones I have that are AT&T branded and much slower compared to Nexus 5 and OPO. Also every time I call somebody, phone drops down to "H" and then connects the call. No calls over LTE.
I'm having the same issue and lately I keep loosing my lte and seeing only the H for 4g

I wonder if it's something with AT&T network and this phone. I'll have full bars (LTE) and no service quiet often. I live in south florida, so we generally have great reception for every carrier.
The issue started for me as soon as I upgraded. I tried the older radio as well. I went back to Chroma 6.0 and all is well. I did star the issue in the tracker.
Well I just got off with att and they reset my connection to the network and so far so good. Lte all around. I will watch the next few days and let you all know

I have actually gotten the same problem, after updating my 6p to 6.0.1, I have lost my LTE and just stayed at H.
I haven't done nothing other than updating, I really hope this gets fixed soon, the speeds arent that bad but I am used to having LTE all around
Well I called att this am at around 8am and tight now at 6pm its been solid. They made me shut off my phone and basically set up my phone network wise as a new phone and boom LTE everywhere
Happening again. I reset network settings and boom all is well for two days
I found a recent post on reddit where a user was having issues with the phone connecting/losing LTE. After troubleshooting with AT&T support they indicated the "APN type" setting was missing an entry and in the improper order.
Changing to the proper order fixed his and others LTE issues and so far it appears that it has fixed my speed issues as well.
The fix applies to both nextgenphone and phone APN's.
Default APN Type on 6p = default,mms,supl,fota,hipri
Correct APN Type from AT&T support = default,admin,fota,mms,supl,hipri
Hopefully this helps.
My S7 Edge G935FD (dual SIM international version) gets only "4G" on T-Mobile in the San Francisco Bay Area, and never "LTE". Is this a "4G vs. LTE" naming issue, or does it lack the band T-Mobile requires for LTE? It also gets "H+" often, in the same location that my old S5 had full bars LTE.
Speed tests with the SpeedSpot app range from 17Mbps to 33Mbps down, and 3.75 to 7.5Mbps up on "4G", but only 5Mbps down and 1Mbps up in H+ areas.
I bought it from tropical_mobile on eBay.

Just naming issue with international version.
@kvsandeepreddy is right.
LTE means LongTermEvolution which is the so called 4th generation of Mobile Networks. So LTE is 4G
1G = Analog mobile Network, I think
2G = GSM and EDGE
3G = UMTS and HSDPA
4G = LTE
FD version is released for asian countries... back in india we use 4g instead of lte

Well, that means that the S7 dual-SIM gets poorer reception than my old single-SIM S5:
In the same spot in the building (at my work desk), I'd get full LTE bars on the old S5, but only H or H+ at best on the new S7 Edge dual SIM. In practice this means ~6x slower downloads and ~7x slower uploads. Pretty ****ty.

Phone being a dual sim doesnt usually affect the sig al strength.. maybe the inbuilt receiver in s7 edge is defective.. heard some other people complaining about the signal strength too

No that's not what it means. The g935fd version is meant to be able to switch to any international firmware version. There are several different modems for each region. You are going to just have to flash different modems in Odin and see which one works best for your region. This does not trip knox or void warranty as long as you do it right because you are flashing official modems. As I said in the other thread you were in, do your research.
Can someone link me to the best modem to used on the dual sim model in the states?
Which modem did you end up using? I am also wondering which version is best in the US.

I'm just using the UAE firmware that the duos came with. It's updated with the June security patch. Only issue I've had is slower than normal download and upload speeds on at&t. It's not that big of a deal, just annoying. I think it has more to do with atts provisioning on their network. I'll post a solution if I figure it out, whether it's a different csc, apn settings or some device setting on my account.
4G is called LTE in USA. If you are getting 4G. That means you are getting LTE.

Yes, you are correct. However, I should have clarified that my statement is based on connection speed tests not on network symbols in notification bar. My slower speeds are in comparison to other 4g devices being tested in the same location on the same network.

Yep. I can confirm the same thing. I have 2 s7 edges. One is a DUOS and the other is AT&T branded. Tested both repeatedly and found that the AT&T branded device is getting way faster speeds than the DUOS. In my particular area the AT&T phone was reaching up to 60 Mbps while the DUOS was only hitting 30-40 Mbps. Very curious on how to fix this since this phone has all the necessary bands to support LTE in the states.

At least you're getting that. My speed tests are consistently in the .72 to 5 Mbps range on the DL and 1-7Mbps on the upload, which is basically about half to a third of what my other AT&T devices are getting in the same location at same time.

Wow your right that is abysmal. Have you tried installing LTE Discovery and comparing the two devices? Check to see if they are connecting to the same towers.

It's not just the bands. AT&T is known for prioritizing their branded phones vs. BYOD phones. It's done by EMEI ... they have a list of all their branded models in a DB and they get priority. TMO doesn't much care. I tested my Duos yesterday and TMO gave me 59.4/12.8 network transfer. It's as good as my 6P. My AT&T sim is in sim1 and is restricted to 2G which is fine since I need calls and texts only from it since it's a work #.
And it does support most of AT&T's bands except band30 which is really new. 4G everywhere else is LTE here as was said in other responses in this thread. It's most likely AT&T deprioritizing the phone as it's a BYOD.

It doesn't have band 12 so I'd save your money. Band 12 is just the deeper penetration 700mhz anyway which around me (SF area) can't be found. My Nexus 6P which has band 12 never connects to anything but band 4 .. ever.

I noticed this as well with my 6p. Supposedly band 12 was to save us all but my phone prefers band 4. I only got a glimpse of band 12 the other day then the phone switch switched back to band 4 when I toggled wifi on and off.
