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?

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 switched my parents over to Cricket from Verizon today. They both have S5's. I set the network mode to lte/wdcma/gsm but it keeps going from Edge, HSPA, and emergency calls only. So I thought I'd try setting it to WCDMA only well I can't as *#*#4636#*#* does NOT work.
While my LG G2 on cricket and my iPhone 7 on AT&T sit and hold both a steady HSPA or LTE perfectly fine without issue which is the reason I switched them.
Any suggestions? Would setting to global be better? I would assume it would make matters worse.
Both phones are running MM and I haven't really kept up with roms/root/etc for Samsung stuff.
Thanks
So maybe this was a bad idea but I'm on boom mobile (verizon mvno) and thought I could save some money and picked up a sprint s7 edge on sale, I just had it unlocked and they flashed it to the 935u unlocked version. The problem is I can't connect to the verizon network, after playing around with it a bit I got it to connect to the verizon lte network but still no voice. In my meager attempts to troubleshoot I noticed I have the options under network mode of
LTE/3g/2g -->> this picks up all networks in my area (Verizon, Sprint, ATT, Tmobile, US Cellular)
3g/2g --> only shows ATT and Tmobile
3g --> only shows ATT and Tmobile
2g --> only Tmobile
So I'm thinking my phone isn't setup right to connect to cdma networks which I thought the 935u rom was supposed to do. Anyone have any tips on how i can further troubleshoot this?
Thanks in advance.
edit: Well I installed a program called 4g LTE switch and set it to cdma only and I was able to make a phone call (3g data also worked) like that but changing it to LTE/cdma wouldn't let me make a call but LTE data worked, if i leave it set to LTE/cdma and reboot it switches back to LTE only.
edit2: Maybe it's trying to connect to volte which isn't offered for Verizon MVNO's yet but i don't see any settings available to disable that.
edit3: When set to LTE/CDMA I could sometimes make outgoing calls, sometimes I would get the double dial prompt, it was very slow to switch between LTE and CDMA so I would miss incoming phone calls.
I threw in the towel and just flashed the latest Verizon rom and it's working properly.
I use Ting, and LTE is available in my area (wife's on same plan) I lost my LTE/4g after flashing Cosmic OS. I've been struggling along with 3g just fine. The phone never showed CDMA - always showed "Global" in the network settings, if I Switch to LTE preferred I lose my signal and have to reset my network settings.
I ordered the MintSIM test kit, and installed it today...and I had LTE. Mint runs off of T-Mobile, Ting runs off of Sprint.
My LTE isn't gone... it's just gone from the CDMA side of things.
Has anyone else flashed Oreo onto a Sprint networked phone and retained their LTE? Is it something with the current ROMS and Sprint?
Experiencing the same after flashing FrankenRom.
Don't get LTE with Tello but I get LTE fine with redpocket T-Mobile.
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.
