voLTE not supported in CM 14.1 (20161119) ?

I just flashed cm14.1 (20161119) build , it is very smooth and good for daily drive but voLTE is not supporting , can anyone please confirm?:fingers-crossed:

There's still no updated modem firmware from Oneplus (which in 99/100 cases comes with a newer ROM for the phone) adding voLTE, no.

No I mean , Still we can use data in oneplus 2 from voLTE right? cant able to select that also...
I am from India, I was using Jio for data alone . It was working fine in OOS.

Cyanogenmod supports voLTE, however the closed sourced binaries from Oneplus does not support telephony though the 4G modem. So there's not much we can do other than use SIP telephone to call using 4G data if you absolutely must use this because of lack of GSM/2G.

So many threads about volte... Just use 2g instead

Reliance Jio functions exclusively on the LTE network, so 2g fallback is not an option. That's the reason for all the VoLTE requests.

There aren't really that many providers who offer free voice calls and data at the price point of absolutely free. Come to think of it, I can't name a single one in my region.

It seems like more then just coincidence that Jio operates in the same region as Oneplus main target audience lives, and then has this offer you can't refuse and by accident the newer flagships supports this provider of free telephony, it makes me wonder how much Oneplus is sponsoring Jio.... ??

use jio's own app jio4gvoice to call

Try the last hydrogen update to have VOLTE.

is ur cm 14.1 after volte working properly? im experiencing a lot of random reboots after volte.... can u tell me which version of cm u using with volte?

I wanted to report my latest finding on VoLTE, so many questions can be resolved.
For the record, I am based in New York and on T-Mobile, so my VoLTE settings are not the same as many of you on Jio in India, so it works for you, it may not work for others.
Now as to my findings:
OOS 3.5.6 - VoLTE works out of the box, no issues!
CM14.1 based ROMS (RR/AICP and variants including Lineage OS) VoLTE does not work!! That includes Official and Unofficial builds.
CAF based ROM (halogenOS) VoLTE works out of the box, no issues!!
AOSP based ROM (CosmicOS) VoLTE works out of the box, no issues!!
Now, I am not sure what the issues is with CM/Lineage OS ROMs that prevents VoLTE to function - but this might give insight to developers.
Is there anyone else I here from USA and on T-MOBILE that can confirm my findings or provide other info?
Thanks

[Need help] VoLTE , Jio, H2OS and the mess!

Hello Guys!
I'm from India and as we were waiting long for VoLTE support, I was one amongst to jump onto H2OS.
Now everyone knows that -
1. On H2oS, there are frequent network drops.
2. On CM14.1 , there are frequent random reboots.
I do know that there are too many threads which state the solutions for above problems but the solutions contradict each other.
1. some say enable only band 3, others say enable band 3,5 and 40.
2. some say install network signal guru on H2os and then flash CM14.1 normally. rest say install the app directly on CM14.1.
I've been trying all solutions for a week now and haven't found any permanent solution.
I would like inputs, especially from people who use 2 sims (1 jio sim). and have flashed H2OS.
Is anyone having a stable phone after flashing H2OS? ; ALSO
Any Idea when updated OOS would come out? (I expect it to be a permanent solution).
PS - For some reason, reverting back to OOS also gives me random reboots and so does CM13.0 do. Please help !

I have Jio in slot 1 and Vodafone in slot 2.
I am on H2OS VoLTE version.
just install network signal guru app.
there in RAT Locking I selected LTE and in BAND Locking I selected band 3,5 and 40.
Also in sim card settings, I have kept 2G/3G/4G(Automatic) as preferred network type.
Also I have disabled "aggressive doze and app hibernation" in battery settings as well.
And in app settings I have disabled app-auto launch prevent option.
In last 4 days I didn't got any network drops.
Also battery life is better than OOS even after disabling aggressive doze option.
On CM14.1, I am getting random reboots even after using network signal guru app. so be on H2OS until Oneplus releases new OOS update. And I feel H2OS is better than CM14.1 because of its camera and battery life.

I try all possible solutions and at last I come on conclusion that everything and all trick is useless till HOS didn't come with either new update or OS adapt HOS modem.
Right now I using RR 7.1.1 latest build with HOS modem with single sim I.e. Jio
VoLTE working perfectly no reboot no signal drop and good battery.
So my suggestion is either use single jio sim or wait for stable build of HOS. Doing tricks and flashing lots of ROM is neither a solution nor give stability.

1. So, on single sim, do i still need to use network signal guru app?
2. In the pic that you uploaded, i see a few network drops. are they major ones?

Network Signal Guru works both on H2OS and CM14.1(RR 7.1) for me...Just lock bands 3 and 5..no random reboots .just a few network drops..these have the frequency of like once in an hour ...and it gone in a minute ...Happy with this...but sure a permanent fix is better..Which will be out before end of 2016...

Hello @aaronblaze. any source of this news (new build before 2016)?. Im toh afraid that oneplus would stop support
Also a quick question. are u using only one sim? cause everyone is facing reboots on dual sim

I am using dual sim and I m sure reboots can be stopped by using Network signal guru on Cm14.1 as well as H2OS (its stabilizes network drops here as there were no reboots on H2 OS in the first place)...Well the source is from Oneplus forums ..Everyone knows that Oneplus said it will give an VoLTE update for OxygenOS for OP2 in this quarter..(ie before end of 2016)..

I am using one Jio sim and one vodafone sim in my oneplus 2 on h2os.i had clean flashed h2os after wiping oxygen 3.1.
i had no reboots and no network drops since 6th december.i had not used and software to achieve this stable situation.
H2os on my oneplus 2 is as similar as open beta 8 naugat on my oneplus 3.

No need of any app or setting. Just one jio sim.
Network drop in image is when I reboot cell. Check carefully its power off status so network drop.

I've had similar problems but I found the solution to be quite easy... though it might now work for everybody. I first did factory reset in TWRP, wiped everything except internal storage. Then I flashed official H2OS version 2.5.1 I believe. Restarted phone (it took like 10 full minutes). Went thru initial setup. Rebooted into TWRP. Factory reset, then wipe everything except internal storage. Clean flashed AICP ROM running android 7.1. Wiped cache. Rebooted. Now my phone works 100% no random reboots and VOLTE works as well.

after hundreds of attempts with all the Custom ROMs including CM14, AICP. Slim, RR I finally am having no problem with Grarak's 1312 build of CM14.1. I selected bands3, 5 & 4o through Network Signal Guru when in H2OS and then Clean flashed this CM 14.1 ROM of Grarak. After a couple of random reboots immediately after installing, the ROM remains steady with no random reboots, full HD capability and no perceptiblesignal drops for the past 19 hours . (touchwood) :fingers-crossed:

I guess this is it...
Just a correction band locking doesn't stick after a reboot..let alone after a clean flash...So Network signal Guru hasn't helped u arrive at this fix...I had read in the changelog of the official CM 14.1 saying some improvement/fix related to Jio network..
So I guess the latest nightly ,ie, 13/12/2016 is the solution for random reboots...Rejoice!...Thanks to @Grarak for ur hardwork...
And it would be kind if anyone who tries this build gives a review about it..

Still no luck

i tried clean flashing cm 14.1 13/12 still trapped with insane random reboots hope someone finds a solution for it can't hold with h2os.

GUYS , I FOUND A SOLUTION! Few hours on RR, no reboots or network drops!
Firstly I flashed latest RR Rom (13th dec). then gapps and OP2 camera.
Secondly I found out that the phone randomly rebooted for me when it switched to Band 40 (I'm in Mumbai, India). Hence I selected band 3 and 5 using network guru app. I never expected the solution to work as it always failed on Cyanogenmod. but it worked on RR . I'm really glad.
PS- I was really pissed before few hours and would love to help anyone who is still in this mess and is having problems regarding RR installation. If u need any help, just put a mail on [email protected] or find me on Facebook @ https://www.facebook.com/tbiwalkar .

Does this solution worked for anybody else.? Please share the experience, weather it worked or failed. I am not doubting tbiwalkar but I had a stable Slim Nougat for a full day and Grarak 1312 build stable for another full day but eventually they both started rebooting randomly with all my old problems came back like a bad coin.

Network location in Android 7.1.2 [tasker]

I tried now lineage, xenon hd and resurrection. In every 7.1.2 ROM I am unable to get the network based location.
Unfortunately the only way I I know to read this battery saving location is by using tasker(which need to work for me)
Google maps is working without GPS. But I think just because near WiFi.
Can anyone check to read the network based location with tasker in a 7.1.2. ROM?
I already checked my APN settings,my sim card and the android right policies for tasker.... No luck at all

It seems that you have similar problem like me and others:
"Network Location Provider" doesn't work with up-to-date Google Play Services
Location not correct when indoors

Thanks for the links. And indeed, it seems like the same problem.
What surprises me is that this bug dont appeal to this community here. For me it is an important feature of google service which we cant use with our OP2.
Furthermore i dont understand why this bug seems to be a bug according to our device.
For me it is ja software bug with no relation to our hardware?
I hope this error gets more pushed soon

For me, this is also a big problem, because I often need to see geotags in my picture where I made this or that photo. But geotags are not recorded in photos, but if they are recorded, then only one place even if I have already passed 2 kilometers.
There are two solutions - to put Google-camera, but there is very dark video in case of insufficient illumination, the second - to put another ROM. I tried almost all the firmware and only two did not have problems:
Resurrection Remix M [5.7.4]
LineageOS 13.0
But one more problem because of which I will soon change my OP2 is a poor autonomy.

Thanks. As far as i know the 3.6.0 updates is based on Android 6.0.1. and therefore no android 7.1.x
However you are right, it seems to be the only fix for now. No Android 7 With this feature.

Look
In some ROMs there is no volte displayed.
But it still has.
In Ur case dnd( do not disturb) mode is activated.
Find it in the settings and disable it.
Also make sure in mobile network settings the volte option is enabled.

Ok guys i solve this issue so first go to settings /sim cards /sim 1 settings (4G sim) /Access point names
Now click on + icon from the top right and create new APN settings.
Name : jionet
APN : jionet
APN type : IPv4
APN protocol : IPv4
Save the settings and set it Done.
(Type jionet in small letters)

Unknown number - VoLTE incoming calls

All incoming calls are Unknown number (no caller number visible) when VoLTE is activated. No issues with outgoing calls (that does make sense). When VoLTE is deactivated, everything works okay. Turning the feature on/off, also with enable/disable carrier check, does not solve anything. Multiple reboots done. Everything worked okay on my Mi Mix 2S with the same SIM-card yesterday, so I'm guessing it's a software issue.
MIUI Global 10.3.7 (PFJEUXM)
Anyone with the same issue? Is it working okay for anyone?

This used to happen to me on the note 5 AI.. And it got fixed after an update.

Hi, where did you find the VoLTE setting?

You probably have to disable carrier check first (*#*#86583#*#* and dial). Then you will have VoLTE option in call settings. Today was a new OTA but the issue is still present for me.

same here... Mi 9t activated volte and now unknown caller.
I wanted to try VOLTE since my calls are so bad I cant understand what callers are saying.

I have the same problem
K20 Pro
MIUI China 10.3.17

I have a MI 9T Global running version 10.3.11.0 PFJMIXM (and if I'm not mistaken the OP's version 10.3.7 (PFJEUXM) is not global but China based EU..)
My provider is T-Mobile Germany and caller-ID with VoLTE is working just fine.
Can it be that it's a problem with china based ROMs (like the EU version)?
Cheers Helmuth

Well, I managed to get in contact with distributer for Mi phones for our country, got their unit (mine was bought from Amazon ES) and reproduced the problem - I didn't pay attention to ROM version on their unit. They've logged it and said that they've forwarded the issue to the devs. Hopefully it'll get resolved sometime in the near future - for now the issue is the same on 10.3.12.0 (PFJEUXM).

I have same issue on global as eu. My provider checked everything and there was no misconfiguration on their side. so, reading these posts I think its phone related. CallerId outgoing is ok, incoming no name.

For me it's the same, for some reason we can't enter diag mode I think. Tried a lot of stuff, all not working. E.g; https://xiaomifirmware.com/guides-and-tips/enter-diag-mode-backup-imei-using-qpst/
Which rom are you using?

Sorry for the confusion, I meant the top part of the guide with three different methods to access DIAG Mode. For me the IMEI is also fine.
If you are using the miui rom you may also try this; https://forum.xda-developers.com/showpost.php?p=80159761&postcount=83 (specifically the two steps Additionnal fixing can be made using the app "Activity Manager" listed at the beginning), for this you need Activity Manager (also mentioned by Ratje_nl); https://forum.xda-developers.com/android/apps-games/app-activity-manager-hidden-activity-t3797985. This does not work on AOSP roms I think, I couldn't find the apks at least. I know this is all kind of messy, since there's little information we have to use a lot of different guides.
I am using Pixel Experience by the way.

So I also managed to get it working using this guide. I used Netherlands_Vodafone_LTE (I'm on the KPN network in The Netherlands), but I can confirm it is working.
Trick for me was to switch to a different rom, I am using Lineage OS instead of PE+, so you may give it a try as well if it still does not work.
