I have SM-N910U model of the note 4 and would like to know how I can enable voLTE. I know my phone supports it, but I can't find it anywhere in the settings nor is it active. My carrier has voLTE, but the phone data drops to 2g when I make calls. I would like to know a way to enable voLTE, so the data stays at 4g while on the call.
Or is there a way to add volte to international roms seems like it is only for carrier branded phones
I have the same problem with Galaxy Alpha on the Metro/ Tmobile Network.
LTE drops to 3 G on calls and often kills Data
during and even a minute or so after the call.
Not good for multitasking- this is a Factory Unlocked Alpha NOT a native Tmo / Metro phone .
The 4G LTE Tmo/ Metro Phones always have simultaneous voice and data so you can be on Web while on a call.
I think some have VoLTE and some have dual band simultaneously in the firmware specifically for Tmo.

Yes you are correct. VoLTE service can be enabled only with layer 1 modified kernel/drivers. The hardware itself definitely supports it, but firmware doesn't. Main reason the Samsung decided to disable this feature is because not all carriers in the world use voLTE service and enabling the service on the user end may trigger unstable and disconnection during call. I have contacted Samsung by Twitter and have yet to receive a response if they are going to enable this feature or not. Will let you know if I hear anything back from them!
Thanks. I wonder if some Dev here can do it for $ 100 .
Really like the size, speed and great Audio quality of Alpha and was going to get the larger Battery but I often can not get back on Internet for a few minutes after a call-
while the Phone says 3G (?) then it goes back to LTE and back to Internet...frustrating .
Am used to Metro PCS VoLTE since 2012 and had not considered this problem with a Factory Unlocked non Carrier Device.
No one reminded me there would be no VoLTE and sometimes no voice and Data simultaneously...
So DEVs figure it out for me and I will have a Tech here do the Install/ Download.
Alternative will be a too big branded S6 either Tmo or Metro which will have a better Camera, even slightly better than Note 4 but I love the small form factor of Alpha- this is Alpha 850 M.
Don't think Samsung will help although there is rumored to be VoLTE with Lollipop so there's a possibility.
Will Lollipop VoLTE perform like a Branded Metro PCS with LTE remaining on Display during calls and simultaneous Internet ?
Anyone have a Beta Lollipop for Alpha that achieves this ?
Thanks.

I followed the instructions like another thread comment said to do but for some reason I couldn't get it to work still but after playing around I was able to get it working.
---- Instructions for enabling: (thanks eyecon82) ----
1. dial ##3282#
2. then click edit (need MSL code) (I used SPCUtility.apk as nothing else worked on my S5)
3. then click LTE
4. It will show LTE ( also known as Band 25), Band 3, Band 26, Band 41 ( I unchecked marked all of these but the LTE option leave that check marked to on)
5. Disable all bands leave LTE check mark to say on.
6. Go to the main directory by hitting back key and choose More at the bottom
7. Choose HDR/1X Selection and choose LTE only Mode. Click OK to save
8. You can either reboot or I just turn on airplane mode and turn it back off to reset the connection.
9. LTE should be working like mine did. But you will not get phone calls until you turn back on the HDR/1X Selection to LTE + CDMA +EVDO Mode but you will get text messages fine.
The items that are underlined in Red are the stuff i added.
---- To tell what Band on: ----
1. ##debug#
2. enter passcode 777468
3. go to LTE engineering menu
I hope this helps because all the other stuff I read would not work for my Galaxy S5 I just bought.
Thanks

Thanks for the info. However, I think its crazy to want to set it up for LTE when you cannot receive phone calls especially since this is you know, is a phone. Calling Sprint and talking about this situation is useless. They all say nothing is wrong and its the device. I'm really pissed off about this but I enjoy the phone. This will probably be the last Sprint phone I will get.

I use it at night or in places that I need fast internet and when I know I dont need a phone for a bit which is why I have voicemail I just switch over to LTE for a bit and then back...but yes it sucks for now until they upgrade the tower over here with the feature needed to use LTE spark devices.
Im loyal to sprint but its becoming more and more hard to be loyal.
Probably just your area, not the phone.
Your area may have LTE but if it doesn't have the circuit fall back enabled yet (tri-band phones) can't drop the data to allow a call and thus they force you to remain on 3G only.
Once your area has everything done it should get better.
I have similar situation that KILLS my battery at home but in every other part of town it all works great :/

Found out from reading the Sprint forums (https://community.sprint.com/baw/thread/157300?start=0&tstart=0), that this is likely not caused by the circuit fallback, but incomplete rollouts of Spark technology. Disabling the new Spark bands has helped me keep a stable LTE connection. Once the Spark rollout is complete in my area, and Band 26 can support both Voice and Data, I'll re-enable it the new spark bands.

Which bands did you disable? Also, are you able to get voice calls when you LTE?
Im a bit frustrated be the place I spend most of my time (where I used to get LTE fine with my S3) I no longer get LTE and its super slow 3g. Calling sprint didn't help, they just say to wait until cell tower updates are finished in the next 6 months.
If I disable the Spart bands, will I be able to keep LTE and voice? Thanks

I disabled bands 26 and 41. This forces the phone to use the default sprint LTE band. It receives voice calls just fine.

But if you enabled the spark LTE bands like the default settings, will you LTE work or does it fall back to 3g? Thanks

LTE works fine because it defaults to the standard LTE band.

Read the sprint link. Incomplete rollout of spark, in particular on band 26 can cause the issue of not being able to switch between 4G and 3G and back.
One of my friends came from overseas a few months ago with VoLTE working on Tmobile US. At least I thought it was.
I did not think much of it at the time, but now that I have my own Z5, and can't get it to work, I'm curious.
Is there any special APN settings needed for VoLTE on TmoUS?
WHen i received my Z5, I noticed there was not any option for VoLTE. I went ahead and flashed the a singapore rom and it is here now but still cannot get it to work. I will try different settings and update.
I am also going to go through a few more roms to see if they work out of the box with it.
WIll it not ever work unlesss TmoUS certifies this device specifically? I don't think that is the case.
It's carrrier dependant
VoLTE uses the SIP protocol for communication. Aside of the implementation of the handling of such calls you would need the necessary data for registering at the server including the server's address, username and password.
I bought my international version from Amazon and turns out it is a Taiwanese version.
I can turn volte on or off but I can't tell it is working or not cause I don't know how to test it.
Testing it is pretty straightforward. Make sure you're on a 4G (LTE) network and place a phone call. Watch to see if you're signal changes to something other than where it started.
My experience is that I have 4G (LTE) in fewer places than 3G, as 4G seems to be less awesome at penetrating thick buildings. So, I don't see what the advantage/concern of VoLTE working or not is. But, I'm happy to learn.

When I make a call, the icon switch from 4G into 3G and H+ (back and forth between the two).
Does it mean no VoLte?

I have the same question too.
That's my understanding of the problem. With my AT&T iPhone, it stays reading LTE when I place calls.
If you see switching from LTE to another network upon dialing or receiving a call and going back to LTE once hung up it's a very strong indication that VoLTE does not work.

THat is correct. My phone switches from 4G to H+ when on a phone call...
After many hours with t-mobile, and also at work, i was informed that t-mobiles VoLTE is proprietary and only tmoUS branded devices are usually the ones to get VoLTE to work with them.
Maybe in the future that will change, they said. oh well.
Until now every provider's solution is proprietary as the 3gpp standard is not finalized yet. So we need to be patient...
When I try to place a video call in the built in phone dialer, it says "Video calling is currently not available. Call connected as voice only." But when my brother tried calling me on his S7 edge, it works fine. I tried turning off the feature in call settings and turning it back on but still doesn't work.
Any one have this problem yet? My best buy order came thru today.
I think it only works between AT&T phones. I've only tried between my S7 edge and my girlfriends S7 edge...both on AT&T. There were a few times she missed the notification to do video and it ended up being audio. The other side definitely has to pick it up as a video call.
Yea, my bro has the S7 edge also and we are living in the same house. Some reason mine doesn't work. When you press the video call icon, the front camera suppose to kick on, but on mine it doesn't. My brother's does...
They had it (HD Voice feature) disabled due to me calling back in October complaining about bad reception around my house. They just reenabled and all is fine now!
I'm having the same issue and att Tech support couldn't figure it out
Call AT&T and have them enable HD Voice feature on your line. Should work then. Make sure you're on a 4G network possibly with LTE as well.
I've tried this a few times with me and my wife's phones. Every time I get the message that its unavailable and audio only. But when we call audio only its HD voice. So not sure what the issue is.

I wanted this on mine and my gf's phones, after multiple fails I started researching. We live in a country rual area, while we still show 4g LTE and great signal. The HD network isn't available everywhere. It shows both phones have to be on the HD network not WiFi and good signal. I recently traveled to new Orleans and we made multiple video calls to each other. After coming home it no longer works. We defaulted to using hangouts and with our unlimited data and good signal strength it works great. [emoji3]

I had that problem the first date I upgraded my S6's software to MM. I called AT&T and complained that I could not make video call between my S7 and S6. The next day both worked, both on WiFi and LTE...
1. From your home screen, press the Phone icon.
2. Tap More on the top right corner.
3. Scroll down and tap on Settings.
By default, VoLTE should be enabled if your Galaxy S7 or Galaxy S7 edge was first used with a carrier SIM that supports it. If your phone was unlocked and subsequently transferred to a carrier SIM that supports VoLTE, you may have to enable it manually.
4. Tap on VoLTE.
Make sure that Use VoLTE when available is checked.
Note: Some versions of the Galaxy S7 may show this setting in a different spot.
Worked for me!
Just a tip, I did some research on this. Att requires both phones to be on their 4g LTE enhanced network. So if one of the callers is in a rural area or low signal, it won't work. I have a s7 and my wife a s6, if one of us is around her parents house (very rural but still 4g coverage) it won't work. However if we both in town or at home, no issue. We started using Google duo when she would visit her family and att video any other time.
I just flashed G930U firmware (Oreo RG3) on my verizon S7 and overall I'm much happier with my phone. But, sometimes when placing a call with a strong LTE signal, the mobile data disappears and becomes unavailable until the call is completed. The strange thing is that it only happens 50 percent of the time. I've changed my network settings from global to LTE/ CDMA but that doesn't fix the problem. Is this a known issue with the "u" firmware? Or is it perhaps only prevalent on this particular version I installed? Any feedback is appreciated! Thanks!

I don't think that the devices stay connected to 4G LTE while on the actual phonecall as it uses the data maybe for the enhanced calling?
I noticed the same change in connections on my Verizon s7 and att s4. It varies and changes during initiated outbound calls or once a call is incoming. Even seconds before incoming calls I see it drop from 4g LTE down to no internet at all. Then without wifi connected during those ones you can't get online while in call. It depends on phone Carrier like Att, Vzw, and even tracfone brand devices.
It usually cuts back to 3g or H+ and even old Edge/gprs or worse, 2g speeds until the calls are complete. Then regular 4g LTE will come back if your phone is working. This is all from personal experience so please don't take what I say over the other developers who might be able to explain what it is happening a little better.
Hope this helps either way!
P.s- It also probably depends on how strong your signal is to determine what speed you will drop down to during calls. Exp. 4g lte,4g,H+,H,3g,2g,edge,gprs,wap.
Let me start by saying that this phone works great. I had it unlocked and practically all is well. There is one issue i am having.
The phone will not automatically reconnect to LTE. My carrier does not support voLTE so it switches to 3g for calls. After a call, the phone stays on 3g and I have to manually toggle the 3G and LTE under network settings to get it to go back to LTE. My carrier uses Bands 12 and 17 and both of these bands have strong signal on the phone when connected to LTE.
I also installed the stock U1 firmware on the mobile to remove all the sprint bloat. Now this issue is the only peeve. I did factory reset it and I also reinstalled the firmware a second time to no avail. The phone did the carrier provisioning on initial start-up after sim was inserted. So I am at a loss.
I had an At&t s10+ which I sold and never had these issues and i did the very same to it as well. I was going to by the OnePlus 7 Pro but i loved the s10+ so i had to go back. It is not such a big deal because i don't make that many calls or receive so many but it is bit annoying. Any solutions?
