So, in your opinion the Tech support doesn't know his business??? and your friend story make more sense???

Listen well, the tech support ask me first if I have an LTE SIM card installed, then check my LTE connection and then validate that there is an issue with the LTE network!

What's possible, that 5.1.1 firmware just created the incompatibility issue with LTE connection, but nevertheless the problem if you like or not, is the LTE connectivity.

Since I switch to 4G, the problem is gone!
[Galaxy S6 General] Whitehat76:
That does't explain the problem with TELUS. TELUS dont share his network with Rogers or Videotron. They shares towers with BELL, and up to now, I've no clue about a S6 having the problem with BELL.

Right..... the same with my S6 with TELUS.. But how long will we wait for a fix to be available ? Are the Telcom really putting enough pressure on samsung as they are saying for a fix , (if it's really the true reason.) I don't think it's fair to pay for a number of months (x) a LTE plan with no LTE services.... in summary, it 's not the customer problem if the provider is not able to provide the LTE services which is in the 2 years contract. I'm thinking like a business here, and why all customers could not do it, thinking like a business ?

ok Good to know. Your're the first that I know that have the problem with BELL.
[Galaxy S6 General] brigon:
The problem is with the modem file. Samsung has made changes to it to support VoLTE on Rogers but that has issues and since it is a unified rom for Canada, it has caused issues for everyone!
[Galaxy S6 General] Whitehat76:
I read somewhere that TELUS still does'nt activated yet VoLTE on their network.. That would explain it.. I wonder if samsung will provide a different modem file until all the carriers activates VoLTE. I hope so.
[Galaxy S6 General] itzik_man:
I just gave Rogers and Videotron as an example!

All Canadian carriers are having the same Android 5.1.1 version, so it make sense that if one or 2 carriers are having LTE issues (with calls) with the 5.1.1, it impacts all carriers with the same firmware and LTE connectivity (if they do have problems)...

Explanation: The most common LTE bandwidth to all Canadian carriers is the 1700 MHz Band 4.

Bell, Rogers & Telus are having other LTE bandwidth (Example; 2600, 1900 & 700 MHz).

So may be the issue is only with the 1700 MHz bandwidth, and phones that are using other LTE connectivity are not impacted (pending on the coverage area you live).
[Galaxy S6 General] ChongoDroid:
No need to downgrade the bootloader, just downgrade the modem to OH8.

Has fixed the missed call bug for me.
[Galaxy S6 General] QAM:
Hola

I just want to chime in here and say that I am on Koodo network and I manually upgraded to 5.1.1 and I too am experiencing the same LTE missing calls issue.

Will try to downgrade the modem to OH8 and test. Annoying as hell that I have to switch to 3G / HSPA to ensure that I keep getting my calls and sms.

"So what you want me to do 'bout that?"
[Galaxy S6 General] Ad.Shk2:
I was on BOH8, and the problem persisted. Im on Fido, got the phone from someone else though who was presumably on Telus.

Upgraded to BOI6 yesterday, no complaints yet but not sure if its fixed yet or not. Fingers crossed!
[Galaxy S6 General] MM13:
Just flashed the OH8 modem. I dont know if it will fix the issue for me but time will tell.

I love this phone but this issue is making me consider selling the phone and buying a different one.
[Galaxy S6 General] bill10:
I'm on Bell with latest bootloader and modem and have had no issues
[Galaxy S6 General] thatsupnow:
Yeah me too no issues for me either. I'm on Bell too and just flashed the first Canadian(they are all the same regardless) 5.1.1 update off of sammobile the second I saw it and everything is better for me. Not sure why everybody else is having so many issues??
[Galaxy S6 General] bill10:
Not sure either. Very strange??????
[Galaxy S6 General] brigon:
Ok, I'm coming from Nexus phones where flashing was easier. Do I flash it thru ADB cuz Odin ain't working and recovery looks different.
[Galaxy S6 General] abbz123:
Didn't work for me.

I'm on rogers using back to note rom

5.1.1 bootloader
[Galaxy S6 General] LNJ:
That pretty much sums up that it's got nothing to do with the BL or Modem.

Rogers will always be the first one to throw someone else under the bus....but if they say it's their network, they're admitting it's their fault!
[Galaxy S6 General] jnhsd0319:
Anybody tried changing the CSC to international version? Was this discussed before?

Seems to me that instead of waiting for future update from Samsung 'Canada', change CSC to international and get updates?

Or am I totally wrong LOL

someone guide me please.
[Galaxy S6 General] ChongoDroid:
Yes it seems this issue can persist on OH8 as well as it just happened to me. It appears Rogers is playing with VOLTE and some other server side stuff but it only affects my s6
[Galaxy S6 General] itzik_man:
You are totally wrong!

Your phone support the Canadian version firmware W8 (unless you root your phone) and doesn't have the international options of the CSC list in your phone.
[Galaxy S6 General] jnhsd0319:
Ahh I see. So I would have to root+ROM+ knox trip for latest update?

I dont really wanna trip knox for now because possibility of Samsung Pay in Canada.
[Galaxy S6 General] itzik_man:
No, that's not what I am saying...

I just answer your question, who is your provider?

I got the latest 5.1.1 update (Videotron), having say that I still have an issue with calls not received or going direct to voicemail.

They are aware of the issue and working on a fix (not Samsung but my provider).

I am not rooted and same as you, awaiting Samsung billing for our Canadian phones.
[Galaxy S6 General] jnhsd0319:
I'm with fido on Rogers device(Same thing), and I do have the latest 5.1.1. But it seems like countries like korea, and europe are getting much more frequent updates so I thought maybe CSC could work.
[Galaxy S6 General] msavic6:
Anybody taken their S6 to the Samsung Service Center regarding this issue or even complained to one of the carriers?

I figure I'll take it over to the service centre in the next couple days and see what they say. I know they won't be any help besides telling me to factory reset and what not.

The other option could be selling it onwards, the S6 still seems to fetch a good amount of money on Craigslist.
[Galaxy S6 General] itzik_man:
Just be patient, I know we (Canadians) are at the bottom of the scale when it comes to firmware schedules update or upgrade, nevertheless tempering with incompatible firmware might do more harm then good (on a none rooted s6).
[Galaxy S6 General] Whitehat76:
Telus told me they are waiting for a fix from Samsung but I suspect they didn't told me the truth...

I Think canadians S6 owners should escalate to the appropriate consumer protection agencies.. While we don't have the LTE services , our bills are still the same, paying for 800$ device, and high rated monthly plans... , and Samsung and carriers are putting the fault on each other. Meanwhile, the customers, are "paying" for this.

Telus told me they are waiting for a fix from Samsung but I suspect they didn't told me the truth...
[Galaxy S6 General] itzik_man:
Samsung takes the generic (Pure Google) Android 5.1.1 and put-on their lair of bloatware and release it to the carriers, then the carriers puts on their bloatware plus a lair of software in accordance with their Network connectivity band.

During this process the firmware might fail and therefore, we the users get bugs in our phones (poor quality of testing).

Remember first release of 5.1.1 by Rogers? they stop the OTA because of a bug (in this case, noting to do with Samsung).

This doesn't means that Samsung's work is free of issues or bugs once he release the firmware, but not in this case.

They may need the help of Samsung, but it's their responsibility to fix!
[Galaxy S6 General] pilotgav:
So our S6s are useless until Rogers finds a fix??
[Galaxy S6 General] msavic6:
The part I find hilarious is that the US carriers released the 5.1.1 update back in June and they were nearly bug free upon release.

The Canadian carriers took an additional 3 months and couldn't figure out to how to test their build before releasing it to the public. They then release it with fundamentally crippling bugs and go quiet.

The amount of people on Fido's forums who are losing their mind over this issue is unreal, there is literally pages upon pages of users experiencing these issues and the response Fido gives to them is we will look into it for you.
[Galaxy S6 General] ChongoDroid:
Unlike my first fix this one will actually work (if my secondary and third tests pass) and should work across radio/update variant so this can be used by non root users.

Standby for further testing, don't want to get anyones hopes up but this should work. I'll either disclose tonight or tomorrow morning.

Damn things were looking really good too but just failed the last test at 25 minutes into deep sleep calls were automatically going to voicemail.

Test using shortcut managers and search in phone app for strings relating to HD voice and enhanced privacy and preferred Wi-Fi Calliing
[Galaxy S6 General] meboy:
Some people having issues and some have none.

I have no issues.

Rogers, Ontario, Stock 5.1.1 latest from Stock 5.0.2, Odin, Stock network settings, Mostly local calls/texts.

It could be a lot of things at this point. The only way to narrow it down is for people with issues to list enough information.

Please list:

- Carrier/Location

- current firmware (modem etc. if you changed things)

- firmware you're coming from

- Odin or OTA

- Network setting as Stock or what

- Local to local calls or far to you

Also, If you're on Rogers and having issues have you checked One Number?

Do the missed calls and texts show up there or not?

I mention this as a bit of a fall back but also it would be interesting to know how far the calls and texts are getting.
[Galaxy S6 General] itzik_man:
I thought I was clear enough when I wrote that my carrier (Videotron) confirm an issue between 5.1.1 and the LTE network??

I will repeat myself by saying that they are working with Rogers (common LTE network) on a fix!

As I said again, other Canadian carriers are using the same band of LTE.

It's nice that some are trying to fix the issue without root...

But, the only fix (for now) is switching off LTE.
[Galaxy S6 General] meboy:
No tech has ever been wrong?

It doesn't even make sense. If that were the case then LTE shouldn't work for anyone on 5.1.1.
[Galaxy S6 General] itzik_man:
Wrong about what? admitting that their testing of the firmware was not good enough? why would they?

Sure It make completely sense, for the fact that not all Canadian carriers are using the same LTE band!!!

Moreover, even within the same carrier you may have some without issues pending location. for the reason that this carrier is using different (multiple) LTE bands!
[Galaxy S6 General] meboy:
So if they admit fault they're telling the truth? That's your logic?

Someone on Rogers is fine. Someone else on Rogers is not fine.

Explain that based on your beliefs.

Think about it...
[Galaxy S6 General] theprodigy85:
Same issue with my phone being unable to receive calls and texts while on wifi. I'm on Koodo with their 5.1.1 release.

Had this problem of straight to VM since the first 5.1.1 update. I have disabled LTE but still have problems. Once I get the sticky / mushy buttons fixed by warranty, I am gojng to root and just downgrade the modem.
[Galaxy S6 General] sangjin66:

I am tired of waiting for the lte data issue to be fixed. Eversince 5.1.1 my data connection has been very unstable.

Anyone know if installing custom rom will fix this?

Waited far too long to root and install Xtrestolite. Now that I have, I love everything. Only issue is encrypting the device.

G920W8 original ROM question for Rogers phone

I purchased the Samsung Galaxy S6 from Rogers. I checked the Device model in settings and it says SM-G920W8. Baseband version is G920W8VLU1AOCG. I went to Sammobile to get a copy of the original 5.0.2 ROM and see if the 5.1.1 was there. I searched for it in the firmware section and used Rogers Canada as the filter and do not see this version in the results list.

These are what comes up in the search

Canada (Rogers) 5.1.1 G920W8VLU2BOH8 G920W8OYA2BOH8

Canada (Rogers) 5.1.1 G920W8VLU2BOI6 G920W8OYA2BOI6

Canada (Rogers) 5.0.2 G920W8VLU2AOG2 G920W8OYA2AOG2

Canada (Rogers) 5.0.2 G920W8VLU1AOE1 G920W8OYA1AOE1

If I search for the Baseband version G920W8VLU1AOCG I get the following results.

Canada (Globalive Wind Mobile) 5.0.2 G920W8VLU1AOCG G920W8OYA1AOCG

Canada (Telus) 5.0.2 G920W8VLU1AOCG G920W8OYA1AOCG

So I am not sure what ROM is the one to download.
[Galaxy S6 General] autom8r:
BOI6 is the one I used without issue. I found it hosted for free by googling the update number.
[Galaxy S6 General] saj222:
After reading all of this I wonder if the reason why these bugs affect some but not all is an incompatibility between the phone's modem / radio and the cell site's physical equipment. Perhaps the carrier's equipment needs a firmware update or is just not up to snuff? Anyone from Rogers here to comment?

Telus uses Huawei base stations and I think Rogers uses Ericsson.

For the record I've disabled LTE (and VoLTE) and am on HSPA and still get texts coming in duplicate and triplicate. Rogers.
[Galaxy S6 General] ChongoDroid:
I think it's the server side implementation of VoLTE, I can't confirm it but it seems as if this is the root of the issue.
[Galaxy S6 General] ChongoDroid:
So anyways I have a script that'll automagically switch to HSPA after going to sleep and it seems to have fixed the issue.

Anyone using HSPA and having these symptoms because if so it'll save me time testing this.
[Galaxy S6 General] KAPABLE-K:
I had the issue with HSPA I have to be on GSM only for it to work only down side no internet and cant send and receive picture text
[Galaxy S6 General] ChongoDroid:
OK good to know. What carrier are you on if you don't mind me asking?

I'm on Rogers and I just let it sleep for 3 hours and it received a phone. So it is working on this end.
[Galaxy S6 General] KAPABLE-K:
I'm on Fido same network but it was hit or miss sometimes it works then sometimes it did not.
[Galaxy S6 General] saj222:
I found this.

Maybe someone can read it and find out where Rogers went wrong. :)
[Galaxy S6 General] ChongoDroid:
I'll take a look at it.

Found more settings relating to VoLTE

I spent a good chunk of time looking at what a mess VoLTE is and man there are a ton of vulnerabilities. So this started as a "fix the bug" issue to more of a privacy audit. Security is my main interest in Android generally so this is right up my alley.

tl;dr don't use VoLTE or at least don't discuss anything sensitive over it.

[Galaxy S6 General] ysrs:
What options are available to someone who upgraded to 5.1.1 and has horrible network issues as others have described? Is there any way to avoid the issues plagued by this update? From my limited understanding, 5.1.1 introduced a secure bootloader, so downgrading is not possible. Is there anything else that can be done? I'm not rooted but I'm open to any options.
[Galaxy S6 General] brigon:
I've seen a couple of people mention that they were able to get Samsung to downgrade it at their service centre (I presume the one out in Mississauga).

Disabling LTE in mobile networks options....using 4G instead
[Galaxy S6 General] ex-28:
can't update

i'm on rogers 5.0.2 was rooted with pingpong root , i did a full unroot with superuser rebooted and tried to take the 5.1.1 ota update but said my device was modified ect... (due to me probablly having a few other things modified themes ect installed) so i fired up samsung smart switch , it showed an update was available , it downloaded the update and went through the whole update proces my phone rebooted however was still at 5.0.2. i check for ota update now and it says the latest updates have already been installed.

my goal here is to update without having to wipe my device now, i do have a backup with smartswitch but would like to get 5.1.1 on here without wiping and redoing everything it almost seems like rogers pulled the 5.1.1 update again.

im on

5.0.2

build xxxxx AOG2

any ideas whats happeneing ?

i plug in phone to smartswitch it just gives option to backup , restore and outlook sync , no seeing anything to try and update again.
[Galaxy S6 General] ChongoDroid:
As others have mentioned using 3G will remedy this.

I am now using this as my daily driver and if I need data I can just switch on LTE (since it won't be asleep on WiFi)

One extra step when I get home is worth knowing that my phone will ring 10 out of 10 times.
[Galaxy S6 General] ex-28:
which of these is the newest

H8

or

I6

however the i6 shows the kies icon which we cant use on the s6 as its changed to smart switch so kinda lost as how to flash the i6 if it is the newer one.

rogers here
[Galaxy S6 General] saj222:
I6 is newer. The further along the alphabet you go the more recent or up to date the the firmware is.

If you are stock you should be able to pull down I6 over the air.

Alternatively, with Smart Switch, do a check for updates with your phone attached and it'll tell you if there is a new build.
[Galaxy S6 General] meboy:
You can use Odin without root.

No idea why everyone is messing with OTA or smartswitch.

From the very little info people are posting so far it seems like people that are doing OTA update are posting more about problems.

Set your network setting to default with LTE on.

Go to sammobile and download the I6 Rogers from 10 01.

Odin it.

Your data/settings will not be erased.

You can do this over top of whatever firmware you have now.

Try this at the very least before disabling LTE.

Please report back.
[Galaxy S6 General] ex-28:
thanks but its telling me i already have latest update available , weird cause my other phone got the update ...

is there a way to flash that version on samobile page as it shows the icon there with kies .. ?

Rooted SM-G920W8 on 5.02

I have the Samsung Galaxy S6 from Rogers 5.02. Device model SM-G920W8. Baseband version G920W8VLU1AOCG. It is rooted. How do I backup the phone complete in case something i do to it goes wrong?

If i down load the Sammobile [Canada (Rogers) 5.1.1 G920W8VLU2BOI6 G920W8OYA2BOI6 ] ROM and ODIN this to the phone will it be compatible and do i loose Root? You say it will not delete any other personal data from the phone, right?
[Galaxy S6 General] meboy:
If you're still on 5.0.2 probably best most people stay there.

There are no major improvements to 5.1.1 anyways.

Samsung is supposedly working hard on 6.0 for the S6 right now so it might be best to wait for that. Hopefully everything is resolved by then. What ever the issue is with calls and texts. No one really knows right now.

Not everyone has the issues but still.

I really meant that post for people who did the first or second 5.1.1 OTA already and we're having issues.

It seems like many haven't tried much. (not all but many) They may not know how.
