VoLTE not working on rooted G925I - Galaxy S6 Edge Q&A, Help & Troubleshooting

I don't know if VoLTE ever worked on this phone, however I am now forced to use it.
I have a rooted S6 Edge, running stock Nougat 7.0 rom, rooted with Magisk.
The VoLTE icon shows in the status bar, yet the phone will not make or receive calls using this service.
Any help will be greatly appreciated, thanks.

G'Day,
That was almost 3 years ago and I am unsure exactly what I did.
However I can remember booting to TWRP and wiping the Dalvik cache and reinstalling Magisk v19.1
Then installed MagiskManager v7.3.4
Any version beyond that I have had issues with on this model.
I am currently using Lineage OS on this phone and is super fast: https://github.com/fakemanoan/LineageOS-Releases/releases
Not sure if VoLTE is working now as I don't have that service with my current provider.
Good luck

How to install OxygenOS or better

Hi guys!
I have seen a thread with more or less the same problem. In most of european countries the white version of OPX comes with H2OS and its the e1001 variant.
The main problem is that the H2OS is laggy in games,very laggy. I have bought three OPXs in Romania and all of them have the same problem. How do I upgrade the firmware/software without root or TWRP? Is it possible? Because the guys that provide the warranty for this phone may void it if something bad happens.
I am running H2Os v1.2.0. It s very snappy with zero lagg but when gaming starts it is very rubbish. Help me here please. What am I supposed to do?
Thanks in advance for the kindly replies! I know that XDA is a bigger community than any other.

You can download the OxygenOS zip and flash it with stock recovery. I would suggest unlock the bootloader, install twrp and take H2OS nandroid there on flash O2OS u can test it for a couple of days and then decide for your liking between the 2 ROMs

I havent really used 2 sims in my oneplus x (germany) with oxygen os but in the android settings it shows all the stuff for dual sim usage. You can deactivate a sim and also set the preferred sim for data usage, calls amd sms.

....
Go to the stock dialler. Select the options from top right (3 dots after the voice search assistant). Select settings>Call Settings>Phone Account Settings>Make calls with. Here you can select 3 options. If you select ask first you'll be prompted everytime you make a call to select from which sim you want to make the call or select either of the sims directly.
But it does not work anymore in OxygenOS 2.1.2, 2.1.3, or 2.1.3-x . Maybe in future OTAs ...

EE (T-Mobile UK) Wifi Calling - How to access?

Network Problem on 4G when using RJIO SIM in India

Hi,
I am experiencing network problem if i use any firmware based on CM. The issue is I get less network and something phone doesnt show any network at all. If I use H2OS or OOS I get proper signals with good speed. I have two ONYX and both have same problems.
I feel the issue could be disabling of a particular band which is used by RJIO in India. Do any body also have this issue? Please post your answers with suitable resolutions if any.
Same here.
If I'm right, you can use Jio Sims only on Lyf handsets, no ?

Well then you have to stick with oos I guess
Try restoring OOS EFS on the ROM you use. If you don't have OOS EFS Backup, Take Nandroid backup of your current Rom to your memory card. Then clean flash OxygenOS and take its EFS backup. Now restore your Rom and then restore Oxygen's EFS over it.
Also, can you reply to my PM? I need your help too.

You cannot buddy. Jio requires VoLTE (voiceover lte) or as they are calling it "True 4G", our phone just supports LTE, so there is no issue with your software, It's the hardware that is incompatible.

Hi, No its not like that. When we talk about LTE, we mean data so any phone in the world supporting the LTE will be able to use the data from the network if phone uses the same band. Now when we talk about VOLTE, its hardware specific and your phone should be able to make VOICE calls using LTE. Its generally a hardware which make enable your phone to send SIP messages using the builtin dialler and then DSP's for the HD voice. But again if your dont have VOLTE supported on your phone you can download dialer application from the vendor ( If they have) and use them to make voice call. The quality may not be as good as builtin hardware but it should be manageable.

VoLTE on A7 (2016)

I got reliance JIo preview offer (unlimited 3 month calling and 4g surfing free) . On my A7(2016) i noticed that Volte sign is not there on the status bar and I was dependent on JioJoin app for VoLTE calling. But I managed to get the VoLTE working on my phone and no longer need JioJoin app to make calls. Stock dialer is working good.
The trick is :
1. Put the JIO SIM in SIM-1 tray of the phone.
2. Go to settings and factory reset the phone.
That's it. After reset, your phone will restart and it will start showing the VoLTE symbol on the status bar. Note that during this process keep your JIO SIM inserted.
Hope it may help someone.

I am using SM-A710FD (UAE). This method is not working for me.
Now I am using with JioJoin App.
Does VoLTE support on UAE handset ?
Please help.
I am not sure about UAE handset but if the model is A710FD then it should support VoLTE. Do one thing, download and flash the latest indian MM firmware from SamMobile. Keep your JIO SIM in TRAY 1 slot during that process and you should be able to see VOLTE.

Did this work f0r you ? I am facing same problem with my Samsung Galaxy A7100 2016

I cannot register network

Hi
I recently received n x820 with rom 19S installed. The reception bars were shown but nothing I did or EE my service provider would get it registered. My sim works in another phone.
I installed twrp 3.1.1-0-x2 and oreo pixel experience is working well apart from no service re mobile. Fingerprint works fine.
I looked at the radio its set to usa or automatic. Preferred network type is TD-SCDMA/WCDMA.
I am in UK does this mean my phone wont get a mobile signal in UK?

Heyyo, have you tried flashing upgraded modem firmware?
Just flash via TWRP and reboot
Either try Developer 466D
https://yadi.sk/d/woKdrlRrv8yhr/Для разработчиков
Or Chinese 26s 05.09
https://yadi.sk/d/woKdrlRrv8yhr/Китай
One of those may work better for you

Hi The_Mard, I tried both but without altering the test settings on radio switcher.
Still no service. The mobile network icon has no bars showing, and on 26S modem it defaults to WCDMA only.
I tried them both with very little time between change. Should I turn on/off phone?
Heyyo, hmm do you know by chance if your phone came with Indian or Chinese 5.8.019s?
One of the only other things I can really recommend is try flashing EUI ROM 5.9.028s the last stable release just to see if flashing it plus all the firmware it comes with will solve the issue for you.
Here's the official link for it

Thanks for the suggestion. I bought from a Chinese seller and the ROM had been customized for the English market, geekbuying had a version of this on it LE_X2_X820-OS-OP-FGXOSOP5801910121S-5.8.019S.zip.
I'll try the 28S but as I am rooted with twrp can I install it or only with ADB?

Mine installed via TWRP it just got grumpy during TWRP install saying there's extra files it didn't know what to do with but it still worked
Twrp installed it and aroma arm64 6.0 provided a nice pixel launcher.
The network search shows 4 bars on the phone which is an improvement. But it can't connect though the region is Other, time and date are London and GMT.
I feel this may be a hardware issue as the network has never registered.
