G920A VoLTE not working NTT DOMOCO - Galaxy S6 Q&A, Help & Troubleshooting

Hello,
I have fixed a S6 with new battery. I decide to call using the Dialer app, but it will jump to 3G. If I force VoLTE via the dialer codes, the phone call will stop.
Any fix for this so I don't have to suffer with terrible voice quality?

VoLTE and Caller Name ID

After enabling VoLTE on my maxx, I lost the ability to use Caller Name ID.
I miss it and was wondering if there are any apps available on the PlayStore that would restore similar functionality. I'm looking for a fully integrative experience - showing caller ID *name* on the incoming call screen, call history, etc
Unrelated, but I when I enable VoLTE, if I'm on a call using speaker, eventually the call boots me off speaker and goes back to the handset earpiece. Every call, eventually. Not at a specific call time, but if it's over 15 or 20 minutes it will. Disable VoLTE, problem gone.

I'm just curious what advantage is seen by VoLTE on the Maxx, which can do voice and data on LTE without VoLTE anyway and won't drop calls when you leave LTE, as Advanced Calling will. Is it the voice quality?
Yeah, improved sound quality (but only when speaking with another VoLTE user).
I'm now on the Droid Turbo so this is even more critical as it doesn't have both radios and can't do simultaneous voice/data if I don't enable VoLTE. I installed the Whitepages Caller ID app and it seems to be an OK workaround. Not as good as the one Verizon loaded (that one integrates much better with the OS) but it'll get me by....

Any way to record WIFI calls?

I have a FreedomPop S5 that uses their own dialer to do mostly wifi calls. It auto switches to voice if the signal is poor. But Galaxy Call Recorder doesnt activate with the FreedomPop dialer. Is their a call recorder app that I can set which dialer to activate on? Since the stock dialer is not used? Thanks.

VIVO V5 Plus Native Video Calling

Hello Everyone thanks for you contribution
here i have a problem due a stubborn brand VIVO.
I want to know how to remove the default dialer so that I can perform a video call through that phone.
company provides 4G VoLTE voice call support but no video calling support.
A third party app provided by telecom operator Jio JIO 4G also can't become default dialler as the stock dialler has VoLTE support for Voice.

Unable to receive calls

Hello,
I bought a mi mix 2s some time ago and it's currently running the china rom because I can't unlock the bootloader the next 10 days.
First of all I can call other people and I can use mobile data. Also I'm able to receive calls if the sim is in my old oneplus one.
Now to my problem:
Today I realized that there must be a problem if someone calls me but I couldn't really figure out under what circumstances the issue appears.
However, I could figure out the following:
If I'm on wifi calls work most of the time
If I'm on 4g I don't receive calls most of the time
If I'm on H+ I receive calls most of the time
If the phone is locked I either get the call or the mailbox answers
If I don't get the call there are two things that happen on the phone that is calling me:
If it's a samsung theres just one loud beep and the call ends
If it's a LG there are fast beeps (similar like if the phone is busy)
Thanks in advance for any help

EDIT: Just figured out that the problem is that the phone takes too long to switch from 4g to 3g since VoLTE is not supported by my carrier... Found some guys in a forum who complained about the same problem but with a oneplus phone... I'm still open for any ideas that could fix that Maybe someone from germany here who uses O2/Eplus network and got the same problem?
EDIT2: http://en.miui.com/thread-935378-1-1.html Used this to enable VoLTE but can't test if it's working until tomorrow
Fixed it by the way by enabling VoLTE with the miui dialer code explained here

Dialer replacement that support video call ?

Is there a good dialer replacement that support video call ?
(since oneplus dialer doesn't seem to support video call )
I get few minutes free bundled from my internet plan.
For me in India, there's a video calling icon right next to the mobile number of the contact, although it can only be done using my VoLTE enabled Jio sim.
