VoLTE option missing - Huawei Nova/Nova Plus Questions & Answers

Hello, I have the CAN-L11 model on the latest firmware and I just realized that I am missing the VoLTE option. Also my connection drops down to 3G during calls so it is clearly not working.

Works for me on Lineage 15.1

About VoLTE update for moto x style

Hello,
I am using Moto x style [xt1572] with custom rom installed LineageOS and a jio sim also. But I am unable to make calls without jio4g voice app which I think is not necessary for the os with volte update. Is there any settings i am missing or any solution to this ??
Please reply..

The VoLTE which you are talking about doesn't work with Jio 4G. It's intended for the US carriers. So you still need to use Jio4GVoice if you want to make calls via Jio.
VoLTE works perfectly in original/official firmware. Including the Jio 4G.
It's implementation in CM/Lineage based ROMs is not correct.

Jio4G works on any rom. JIO VOLTE doesn't work on any rom on moto x style. As long as motorola doesn't support jio volte, no one can do anything to make it work
Open dial pad and type *#*#4636#*#*
Select phone information.
You can turn on your VoLTE option from: "VoLTE provisioned".
Then go back in "Network Settings" for the "Enhanced LTE" switch.
At least that's where it is on my stock firmware. And BTW, it works.

Le max 2 all volte problems solved!

I am using le max 2 in India
I am having multiple problems with this phone
First of all I rooted it and installed lineage os on it.
I do not know about the modem version at that time.
Jio Volte was working fine, but sometime jio to jio outgoing call not worked.
Also fingerprint was useless.
After that I installed cn26s modem
With that fingerprint was working and response was good.
But volte incoming calls was not working. (Always out of coverage area.)
Only outgoing and data was working. Also jio to jio outgoing was working fine.
Then I installed developer466d
Same problem as cn26
Then I installed Indian 19s
No luck same as cn26
After that I installed Indian 17s
Fingerprint stop working.
Volte worked but sometime.
I have no idea how to fix volte
Now I downloading 19s full firmware.
If any one have any clue
Here is the link to all modem

I just flashed full firmware yesterday indian 19s.
Just after flashing only outgoing was working.
Then I leaved the device as it is with 19s.
In the morning incoming started to work itself.
I also noticed same behaviour with other ROMs
Leaving the phone with rom installed and sim installed for few hours worked.

How to enable vowifi on galaxy on7 pro?

[SOLVED] Sorry, I found the wifi calling button on the phone.
I have Samsung Galaxy on7 pro which is VoLTE phone. I am using Reliance Jio.
Both Reliance Jio and Airtel have announced Vowifi availability in India.
I couldn't find any way to enable vowifi feature on this phone. I tried to use *#*#4636#*#* to get phone info but unfortunately this code does not work on this phone.
The os is Android 6.0.1 and there is no hope for ota update to Android 8.0
If vowifi couldn't be enabled on this phone I would like to flash Android 8.1 in case I could get vowifi feature.
