Unable to make calls while connected to 4G(LTE) - Samsung Galaxy S7 Edge Questions and Answers

Hi guys,
I've been a visitor of the forums over many years now. Learned quite a bit reading all these great posts.
I'm constantly changing phones but always return to Samsung. Now I'm moving from the Note 5 to the S7E.
I just picked up the S7E today and I'm very impressed. Phone looks great and is very fast. A couple of hours playing with the phone I noticed a big problem. I'm unable to make calls when my phone is connected to LTE. When I attempt to call someone it doesn't drop to 3G to place the call. Also my Internet stops working. I can't force 3G/2G and my only option is to reboot the phone. Once I reboot, I'm able to force 3G/2G and I'm able to make calls and Internet works before and after calls. But in this mode I'm stuck without LTE.
Do you think this is faulty hardware? Or should a software update fix this?
Many thanks to XDA community!

Who is your carrier and which exact variant (SM-G935T, ...935V, etc.) of the device do you have?
Are you in the U.S. or somewhere else?
If this is a carrier-specific device being used on its intended carrier's network, then this problem is something their support people could (and should) be able to help you with.
There aren't enough specifics in your post for anyone to have a reasonable shot at helping with this issue.
Also, I just noticed you posted in the general discussion forum. This post is really asking for help and would be a better fit for the Q&A forum.

Hi,
I bought the international version (SM-G935F). It does not have any carrier branding.
I bought it in Switzerland and I'm using it in Switzerland with a Swiss carrier.
Mods, please move this thread to the appropriate section if it doesn't belong here.
Thanks!

I also had an S7 Edge with calling issues (dropped every call after a few seconds, possibly trying to switch from 4G to 3G or from 3G to 2G). It turns out it was defective and the replacement works as intended.

Just did a hard reset now.
Was able to make one call. When I tried a second time, same issue. Reboot seems to allow me to make an initial call but then same issue again.
Will take it back tomorrow and hope they have a replacement in stock.

The Feature you are talking about is Voice over LTE! Here in germany this is only anabled in the branded Provider Firmwares like from Vodafone or t-mobile germany. If you have an unbranded Device like i have G635F than VOLTE is not working cause its locked! Not Sure how this works with swiss Providers. In germany VOLTE only is working with Company branded Firmware! And to be honest i am rally worried about that cause i will never use branding Firmwares.

Update: took the s7 edge back to the store and of course the phone worked perfectly. There was nothing they could do as the phone worked fine and we were able to make many test calls.
Phone worked fine during the day but when I got home the problem started again. After some testing, it seems the problem only occurs when connected to 4G+/LTE+/carrier aggregation.
Couldn't place any calls at home this morning but at work where I only get 4G everything works perfectly. Very strange.
In Switzerland I don't think we have VoLTE. When we place calls the phone drops to 3G but for some reason it's not happening when connected to 4G+.
Ill do some more testing today to see if I can find any 4G+ areas near work to test.

Same issue
Hi,
I just got my new S7 Edge (SM-935F) and I think I have the exact same problem. When I'm in the city where I live (Morges, Switzerland), I can't make or receive any call while on 4G but data works. Switching to 2G allows me to make or receive call though.
Then, when in a different city (50km away), everything works as it should be (call and data on 4G). Did a factory reset and it also didn't change a thing.
The guy from my carrier's shop (Sunrise) told me that there was a known issue with 4G calls on the S7 and S7 Edge in different cities (mostly in the canton Valais). I've also been told that Samsung is working on an update to fix it so returning the phone to get a new one would be useless. Did he tell when that would probably be fixed ? Of course not..
I hope someone find a fix soon
Looks like the antenna gate from the iphone 4 but seriously how can something like that still happen

Hi,
Looks like we have exactly the same problem. I work in Geneva but live in Gland. Today I tested my phone in Geneva and it worked perfectly everywhere while in 4G or 4G+. As soon as I arrived home in Gland I'm unable to make calls so I have to force 3G/2G in order to receive and make calls.
By the way I also have sunrise as a carrier.
Good to know that it's a known problem and that they are working on a fix. It's very annoying... Hope they fix it soon!

Missed calls despite good signal

Hi,
Just got the Galaxy S, im on orange and im finding that the phone is going straight to VM even with full signal, this seems to happen about 80% of the time, i get a message straight after saying i have a missed call. It seems to be worse when its in my pocket, i had a similar issue with my nokia 5800 but not as bad, i just thought it was the phone getting old.
I have a new sim but same number etc.
Anyone else having similar issues?
I had the exact same thing on mt old i8910hd on orange.I put it down to the fact the phone had a few knocks but who knows? Hasnt happened once on galaxy s with vodafone
Also on Vodafone, not encountered this problem yet.
You may have to consider that this is a problem with your provider. In the netherlands, tmobile had an issue with this due to an overloaded network. Since you live in london I guess that would be a likely reason (tmobile mainly had issues in crowded areas). My suggestion is to try and disable your 3G connection and see if that makes a difference. Here people couldn't receive calls when their 3G was on but when they turned it off, the problems seemed to disappear.
If this works for you, you may want to contact your operator. The sounds to me like it isn't a device related issue.

Thanks for the reply, stepping down to 2g did seem to help, i have found some other posts on other forums, one forum suggests that orange are aware of the issue, lets just hope they resolve it soon.
I had this problem with orange at least 8 months or so, so i wouldnt hold your breath

Problems with i9000M

Hello,
I bought my phone brand new and I unlocked it myself using the method discovered here. Recently, I noticed that some incoming calls go directly to voice mail although I might have clear or even perfect reception. Since I live near the US boarder, switching to US providers solve this issue; I’m with FIDO and have an un-rooted stock ROM (2.1).
Thank you
no problems here in the Toronto area
not sure what you can do, it's tricky when i visit Niagara Falls, sometimes it switches to AT&T on its own (using old phones)
i'm sure Galaxy S will do the same thing like all other phones, i'll most likely just pick which ever signal is strongest

Mobile data problem

Sadly its become apparent that something is wrong with my Yota 2, when losing the network signal when out in the sticks it will not reconnect mobile data when I'm back within decent network coverage, the voice and SMS work okay but the mobile data doesn't, even if i get full signal bars. Toggling Bluetooth and mobile data make no difference. The only cure is to turn the phone off an on then it fine until the next time.
I've checked my 3 UK APN settings and they are all as expected.
I've contacted yota support an they want me to send it to their service partner (premiere eurocom ) I have to send it at my expense and wait their diagnosis.....but I'm not sure how yota will be billed for this.
Has anyone else experienced the problem?
I'll try a factory reset before I send it, just in case...
Sent from my YD201 using XDA Free mobile app
I didn't encounter such problems so far. I was a bit worried a few days ago, as my Yotaphone kept losing the GSM connection entirely (I was back to the PIN code input screen multiple times every day), but then it also did happen on my good old Ericsson t39m, so I suspect it was more an issue with the local GSM network.
Can you try with another SIM card (maybe even another carrier) to see if this happens regardless of the carrier?
Did you change something (apps, settings...) on your phone recently? I'm asking just in case, you certainly thought about that already, so don't get offended by such a basic question!
No worries.....Thanks for the input, what network are you on?
I tried a factory reset and that didn't make any difference, that should eliminate any fiddling or dodgy apps too, I tried the Sim back in my HTC One and it behaved perfectly in there, upon returning it to the Yotaphone I lost data comm twice in a matter of hours only reaquiring after turning the device off and on. I also double checked the Three UK apn settings and they are as they should be. I could try another network as nano sim are few and far between!
I've now returned it at my own expense (Thanks Yotaphone!) To their repair partner Premiere Eurocomm, I'm not sure what will happen now as for all I know it will pass their testing in their repair labs, I'm hoping they will just send a new device .

Update......
I received a new phone under warranty, I set it all up and sadly exactly the same problem occurred. (Passing through an area of poor or no network service, the mobile data (3g or LTE) will not reconnect until the device is switched off and on again)
I now believe this is an incompatibility between Three UKs mobile data network and The Yotaphone firmware/hardware.
To crudely test this I bought a Vodafone payg sim and carried both my phones with me and these are my findings
HTC One M7 & Three UK sim......no problems.
HTC One M7 & Vodafone sim.....no problems.
Yotaphone 2 & Vodafone sim.......no problems.
Yotaphone 2 & Three UK sim....fails to reconnect.
So my options no seem to be;
Try for a refund on the device.
Change network to Vodafone.
Wait for a fix from Yota.
So I'll call the support line later today and see what they say. Could any UK users let me know what network you are on and if you have any similar problems please?

Sorry for the delayed answer...
I'm using the Orange (France) network at home without any particular issue, the troubles only happen (so far) when I'm traveling abroad, which I frequently do for work.
I'll try to list more precisely which carriers are subject to network connection issues, although it's not easy to see which carrier you're roaming with (on my old Ericsson phone, the carrier name is displayed prominently on the screen, whereas you've got to dig in the menus on an Android phone to get the carrier's name...
Okay so I called yota support an updated them and as expected they just blamed Three, so only after asking for a refund did the agent pass the problem onto Yota for more technical help, I won't hold my breath waiting for contact but if nothing by the end of next week then I will be insisting on a refund. kind of spoiled my fun this has
Sent from my YD201 using XDA Free mobile app
It would be a shame if they don't seize the opportunity to further dig into the subject and find out the technical cause. After all, they aim at a worldwide distribution of the Yotaphone 2, don't they? And it'd be a shame to see you go, too...
An update.....
I've not heard anything from Yota support but have made progress myself, I discovered in the mobile networks settings that you can select your network manually rather than automatic, by doing this two options for Three appear in the list, Three and Three UK.
I selected Three UK and since doing that the problem has not happened at all over three days of using the phone, including passing through the areas of no network coverage that would trigger the problem.
I'm hoping this is fixed.
Footnote: whilst sorting this problem I've been using my HTC One that has had its lollipop update and I'm loving the lollipop, can't wait to get it on the Yota

Any more updates? Got my phone today and got the same problem.
I got Tele 2 in Sweden and it wont connect to 4G. It will get 3G connection but very weak signal and it will disconnect and reconnect atleast once each 5 minutes.
I did also set network in manual mode and it works better but not as to expect from a phone.
Im also going to try with another carrier but im kinda locked to my current one...
On a side note, I've had twice an issue with SMS and the YotaPhone 2.
I've received the same message over and over about 50 times, usually separated by a minute, but sometimes the message shows up again only after a couple of hours...
Not a big deal, but annoying nonetheless. I suspect that the local phone network (in Congo) is to blame, but I'd be curious to know if this has already happened to anyone else, as my other phone(s) do not display such behavior. I usually have the "Welcome to XXX network" SMS repeated a couple of times, too, in those situations, though usually not more than three or four times.

Please whats their customer care mail or phone number ive been searching all over for it my phone just died as well.
I'm having exactly the same problem, I've had my phone for three days and it already happened twice. Putting the phone on airplane mode does not solve it; I have to restart the phone. I only lose data connectivity, but I get signal and I can call just fine. Btw, I'm using the YD206 version with Jazztel in Spain.
I'll try now with the manual network selection and ser if the problem dissapears.

Hello,
I have more or less the same problem ... but with no real solutions
After upgrading MM I lost the LTE signal but not all the time.
When I start my phone I have the LTE signal with good bandwith and good quality of reception.
After some time (5min, 15min, ... no really logic) or every time after driving with my car and I expect changing Emettor many time, I loose the data. I have no more LTE, H+, 3G etc... no more data and I loose a lot of quality of signal like my "modem" lost a lot of range of signal available.
I Flash and reflash MM and no solution.
When selection manually the operator, it change Nothing for me
When I change APN with a new one (2 APN are available for data (for french people SLSFR and WEBSFR)) the data is coming back but just few time.
When I come back the the first APN, data is not coming back until restarting the phone.
I have a third APN but with only 3G connection and with this one, I have no problem. Data is always available...
Really Strange. The problem is only due to LTE signal
For this moment, I will try with Lolipop if the problem don't occur anymore.

Hi Benetnath,
I find no issue with SFR.
I spoke with the customer service and they don't find any problem on the network.
I read a lot of forum and it seems that the problem is not only on Yotaphone but on lot of quite "old" phone.
They change some parameter on the network (what, I don't know, is it regarding the fact that we can travel everywhere yet in Europe using our data mobile...)
You can easyly find some post with looking about "SFR data probleme sl2sfr oneplus" through google
I expect that the problem is only on SFR but I can't be 100% sure.
Due to the problem seems to be a network "problem" or french network parameter, I think we will never have any answer or solution. It is sure that yet we will have no more update on yotaphone.
The only one solution I can give you today (avoiding changing operator ) is to use only the APN : Wapsfr
With this APN you will never be connected in 4G but only in 3G. No problem with cost or anything else (pas de risque de hors forfait) but in my case, the reception quality is really better in 4G with 800Mhz frequency that 3G in 2600MHz I believe.
Without 4G I can't receive anything inside my house.
I will keep you and the forum in touch if I find a solution.
Changing to an another operator is not so easy because for low price all the alternative operator like laposte mobile, pristel, NRJ or some other are often on SFR network with the same APN (so I suppose the same problems)
It is maybe also because SFR launched the VOLTE in June and the problem is more or less since this date.
VOLTE is maybe the problem ? When I receive a call I lose the data and she is not coming back

Hi, I have the same problem. And I think the problem go from Free : Before I had SFR and Bouygues, I never saw the problem.
Sometimes, just activate the plane mode, and desactivate it, and the LTE comming back. but another time, I have to reboot the Yota.
Hello xNiux;
With Free, I found also lot of data connection problem on Google.
The main problem with Free is that the mobile should sometime connect to a Free emettor and sometime to Orange.
So maybe your phone is not connected on the good emettor and it is the reason you lose your data connection. I can't be sure because I have not Free Mobile but it is what I wrote.
==> Maybe can you go to "choose operator" and select only Free...
For SFR it is a quite new issue, around june. Before I expected that it was a wrong ROM when I uploaded my phon to MM but it is not the reason.
Even with choosing manually the operator or use airplane mode, nothing is working. I need to restart or open/close my SIM card.
I make a "call" to the RED team to find a solution.
They wrote me this morning that now everything is fine and work well... but this morning I lose another time the connection.
For the moment :
Free is not working with Yotaphone
RED/ SFR is not working with Yotaphone
To be check with Bouygue or Orange to maybe choose an another operator ( I don't want to change my phone)

Project Fi After 6.0.1 update cannot make calls on Tmobile but texing and Data work

I have been entering the sprint code every couple hrs to get my calls to work. Project Fi support has no idea why or what is going on. The had me run a bug report. Hopefully that will get this resolved. Any one else on Project Fi having this issue?
Jayson
Still waiting to hear back from Project Fi team. I just spoke with the Nexus support team and was told there is no going back to 6.0 from 6.0.1. The tech I spoke with said that they have logged 7 calls with the same issue me. Mine now makes it 8.
Even though I am a bit frustrated with this issue Google support folks are 1000 times more knowledgeable and easier to work with than Verizon. This company gets how to treat and deal with customers.
Still not working yet. Google is going to give me credit for the inconvenience but I am beginning to lose faith in them getting this resolved. Switches back to T-Mobile and I keep missing calls. Uhhhhg. I really want to stay with Project Fi but I may be forced to look elsewhere for cellular service.
Have you tried *#*#34963#*#* ?
I had a similiar issue to you.
Where I live and where I work I get a stronger signal from Sprint than T-mobile.
After I updated my phone to 6.0.1 I had problems connecting to Sprint's network.
I used the "FI XME" dialer code and that seemed to fix my issue:
*#*#34963#*#*
I found a post in the Nexus 6 forums with the Project Fi dialer codes:

Another reference for the Project Fi dialer codes:

Ah yes then that's a problem, the Google update to 6.0.1 has caused all kinds of radio problems so let's hope they fix it quickly.
My issue seems a different. The Data and texting works fine on WiFI only, Sprint and T-Mobile. The issue is calling in and out on T-Mobile. Instant failure.
I'm having the same problem but I think it only happens when the phone connects to band 12 LTE on T-mobile. It seems that VoLTE isn't working properly. Can you check what T-mobile band you are on using this app:
https://play.google.com/store/apps/details?id=com.blueline.signalchecklite
Says Provider: T-Mobile B4
I'm having the issue where my data speeds suck. Since update

Be careful! I did this on my last 6P and it completely messed up my radio and prevented me from making calls on Sprint (no it wasn't because of the SIM card as I tried 3 of them) . I had to RMA my device. My advice is not to mess with that menu. I have done it on other devices without issue but it seems as though once selected it cannot be undone.
I just found out yesterday that the engineers have not even looked at my bug reports yet. They were sent to them yesterday from what I was told. They also had me order a new sim card as well to rule that out. The support or lack there of up to yesterday has be ridiculously unacceptable. I get the feeling that they are just trying to pacify me and not doing anything in hopes that a new release will come out an magically fix this issue. Very frustrating.
Problem Fixed. After dealing with this for several days I asked a supervisor how long was acceptable to leave a customer with an open issue affecting cellular service and to be missing calls. He provided me a RMA and a new phone was sent. All seems to be work with the New replacement phone they sent.

Yes be very careful in that menu. I was just looking at the menu and my finger some how hit a different band. Took me about 4 hours to figure out how to fix it. There are some tuts here on that issue that will help. Also there's a way to get the international bands to show up

Note 4 no longer supported by T-Mobile No Network

My husband and I both have a stock N910T. When we woke up yesterday neither phone would get signal, and not even make wifi call. Went to TMo shop today they told me that they were no longer sending signal to Note 4's (Thanks for the heads up TMo). We really like these phones and I wonder if I could root them and flash a stable ROM and get service on them again. When I pull the sim it shows 5 bars, put the sim back and X. I have rooted many phones, but not since I got this one 6 years ago, so I'm sure I'm a bit rusty.
Any advice highly appreciated. TIA
I'm in the same boat with the note edge. It stopped working friday night for me. Put the sim in a stock note 4 and same thing, so I thought my sim card died. Went to the tmobile store on saturday and they said 2 people had came in with the same issue and they had note 4s.
What I don't understand is how they can just stop supporting a phone. I thought that if it accepts the sim card and has the proper bands it'll work. I mean for ****s sake my car takes a tmobile sim for a hotspot and traffic updates.
same exact. i just factory reset and updated stock to see if it would fix but it wont. Any solutions here??
Try to:
a. flash a custom TWRP (recovery) with Odin
IMPORTANT - after you flash TWRP PLEASE TAKE A FULL BACK-UP!
b. flash a custom ROM with root
c. why root? because you can change the build.prop file and "pretend" to be another phone (newer more likely) so that the lovely t-mobile can still allow your phone to connect to the network.
This way you have zero costs, you keep your note 4.
Unless it's too complicated or the procrastination level is TDH (too damn high)
Or you have the cash and buy something new(er).
There's info on this forum about all these steps.
Before you do anything - go and read, search on this forums and on youtube. There are a LOT of tutorials.
Please be careful and READ. Get educated about custom recovery/ROM's.
You will get good knowledge and your satisfaction on make things work will be enormous.
You will be responsible on your actions with the phone.
Good luck.
mine is already rooted with a custom rom. which parameters do you recommend changing in build.prop?
my audi is older than the note 4 and data works fine and calls work on a motorola L6 from 2005, so I doubt it's the age.
someone on reddit came up with a temporary solution until they fix this. you'll lose 4g/LTE tho
To set to 3G/2G turn on airplane mode and enter *#2263#* on the phone dialer. Then select GSM/WCDMA Auto. After that turn airplane mode off.
Hey all - same issue here - Note 4 stopped working Friday morning. I tried everything on my end (factory reset, ROM flash, SIM swap, etc). I even tore the phone down and checked the connections. I ordered a replacement SIM / SD card tray reader thinking that was the issue. Now I hear others having the same issue. I live in Colorado FWIW. Calling into T-Mobile now to see if I can get some info here.
---------- Post added at 02:50 PM ---------- Previous post was at 02:31 PM ----------
After speaking on the phone with a tech support person, T-Mobile reported that they were aware of an issue with Note 4 users not being able to access the network. They said that they "were in contact with Samsung and were actively working on an issue" and reassured me that they would have a solution for customers soon. I sure hope so because I do not want to give up my Note 4!
Note 4 user here too. This sucks. I did the workaround on the dialer posted in one of the above posts, and now it connects. Says 4G at the top, but probably only 3G. That's fine for me in the meantime, but not acceptable in the long run. I just spent 2 days wiping the phone, unrooting, etc only to find this now! Got lots of work to do to get it back to my rooted state. Thankfully I have the backups to do it, just have to find the time now. Thanks T-Mobile!!
Has anyone heard any more on this issue?
Just had the same issue. Called T-mobile support and they had no idea of a widespread issue, said it was likely HW failure. I got a new SIM and that didn't help. Called local cellphone repair shop and they indicated they'd had several calls about this issue and fixed at least one so far by replacing the card reader. I applied the workaround above and got the phone working again so I don't understand why a new card reader is going to fix this.
Note 4 seems like it's back working on T-Mobile as of last night.
HI I purchased galaxy note 4 3 years ago in the first time I put him on i has that problem yet
But I live in curacao in the Caribbean and I think that the mother board was not good.
Then I has flight to medellin Colombia with the phone he began working I was glad but when I arrived to curacao from medellin the same problem
Sometimes he is working sometime not

Note 4 seems like it's back working on T-Mobile as of last night.

Thanks for the update! I reversed the workaround I applied earlier and mine is back to 4G LTE now.
Any update on this issue?
The N915-T is spotty and I'm trying to figure out why. It was officially kicked off the network by T-Mobile, but it still works. It connects to most towers but not to a particular one. Whenever I'm on that block the network can not be found. If I walk two blocks away it would connect to another tower and I can make calls. If I walk back toward the 'faulty' tower while on the call, the quality would degrade, the call drops and the phone would lose signal.
This would NOT happen with other phones - not even an older Galaxy S2.
This is likely a different issue altogether, as the phone actually connects and works elsewhere. I'm just hoping someone has an idea.
