4gLTE dropping to 1x while making/on call - Note Edge Q&A, Help & Troubleshooting

Hi All,
I hope this helps someone out there, just got off an call with VERIZON about 1 hr later and they were ready to get a replacement out to me.
Found out that I declined a feature HD voice (no charge) and if you do not have this feature it will drop your calling reception to 1x.
After hard resetting, new SIM replacement, etc... Found out you have to go in Settings --> Advanced Calling --> Activate Advance Calling, Restart the device and 4GLTE sticks.
:good:
I hope this helps others.

Yes, this is how VoLTE or XLTE works. It allows you to have voice and internet simultaneously. However, if this service is not available in your area, and the option is enabled, it can have adverse effects -- ie: static calls, one person cannot hear another, etc.

Also, if you go from LTE to 3G the call will most likely drop. I have had that happen a few times while on the phone.

UK Networks 2G Data Call = Missed Call - Help Needed

Hi All,
I would like your assistance with something. All it's going to take is a call to you network provider after a quick test with your phone.
The Problem:
Do you miss calls even if the phone has full signal and may even be in your hand? If the answer is yes and you are on any network other than Vodafone, then you are experiencing my frustration. It's due to the networks not prioritising voice calls over data calls when there is an active 2G/GPRS connection. This is not related to the handset at all it's network-side.
The Test:
1. Turn your phone to GSM mode. For my phone it's Settings > Wireless & Network > Mobile Network > Network Mode
2. Start a data connection
3. Use an app that is data intensive e.g. Google Maps
4. Use another phone to call your phone
If I am right, due to a lack of Dual Transfer Mode capability, your phone will bounce the call.
The Solution:
The only solution is for you to call your network and complain. YOU PAY FOR THE SERVICE SO THEY SHOULD PROVIDE IT.
My network is Orange and they say they are looking into it but I have no confidence in them as they say they have never experienced this. It's been the same since I had a Nokia N95 but smart phones these days are so much more data intensive so the problem is greater.
Thanks for you time.
On all the phones I've had with Voda and O2, if I'm using data and get a call, my net connection drops and I get the call.

[Not-Fixed] How to install new Z3 D6603 LTE on AT&T network

[Not Fixed] see bottom of this post.
It is fairly easy to install a new D6603 to work completly on the AT&T network. It is not so easy to find the answer of how to do it in the threads and posts. I tried many suggestions and wasted a lot of time. Hopefully this will save you from that fate.
First you must know that you can't use the IMEI number of your new phone if you want it to work completly as it should. If you use the Z3 IMEI you will have trouble with data of various sorts and the phone will go off line when on LTE after 20 or 30 minutes and you will not receive calls or SMS messages. I do not know why but it has been suggested that the AT&T network does not recognise this phone so it causes trouble.
If you have an AT&T nano-sim from your old phone then just put it in the phone. (Cut downs work but can cause other problems some say.) When the SIM is inserted for the first time into a new phone there is a prompt that asks if you want to download the APN. Hit 'yes' and the phone downloads the APN itself.
If it does not ask then go to Settings>More>Mobile Networks>Prefered Network Type and be sure LTE (Preferred) is selected. Then connect your phone to the internet and then go to Settings>More>Internet Settings and select AT&T. You should be good to go.
If you need to get a nano-sim then go to the AT&T store or call and they will give you one or send you one for free. You will need to use the IMEI number from a LTE phone that is already on the AT&T system. You can use your old phone or borrow the number from someone. If the rep installs the sim in the Z3 with the 6603 IMEI don't worry. Just call support later and tell them you sent your new phone back and want to go back to your old IMEI or have a new IMEI (from an existing AT&T phone). They will enter it and off you go. The phone from the IMEI will show in the picture on your account page. Big deal!
Update: This worked for hours last night but this morning it is back to not receiving calls. Simply turning wifi off and it began to receive calls as GPRS was switched back on. My wifi was on which has been said to cause problems. I will test with wifi off and report back. Had "no service" instead of AT&T on upper left of lock screen. A full shut down for several minutes than re-boot solved that.
YMMV. I've been on ATT with a Z3 purchased from Sony store for several months and it was registered in an ATT store by scanning the IMEI off the box followed by updating Internet settings in Setup. ATT online shows unknown model but everything works including LTE and MMS. There is something else involved when problems like this occur probably some setting not getting reset. I registered the Z3 on a new line with a new Sim card because I wanted to take my time moving stuff off my old phone--this may have avoided the problems.

AT&T's system sometimes takes a while to get updated with new IMEIs that trigger LTE provisioning for a users' account.
Once your account is provisioned for LTE you never have to worry about it again, but sometimes if you have a phone the system doesn't recognize, it is a pain to get AT&T to properly provision your account. Supposedly properly trained in-store reps can do it - the key being "properly trained" - Never try to do anything "unusual" by calling AT&T customer service, and NEVER use a franchise/kiosk in-person for service - make sure you're at a corporate-owned store! Even then, some stores might have incompetent staff. I've been lucky that all of my local corporate stores are pretty well staffed.
So you are saying that your Z3's with wifi and LTE on with AT&T are working as they should?
With LTE off my phone responds normally with wifi on. With LTE and wifi on it will not respond to calls after a 30 minute sleep. It does not show missed calls. Calls go straight to voice mail after 2 rings. Could you tell me what level your LTE dBm's are? Thanks!
I was told not to give them my imie# but, after recvng the minisim I had to call them in order to 'provision' it to work at all and they needed that #. I have never had any problems personally and am assuming this may be because you gave them the wrong #. Again I am only guessing. Oth, if I had had a different imie to give, I would have done so myself.
It is very strange and I am feeling it is more signal strength related than how you provision your phone. (Once it is provisioned correctly.) It seems that more people have less problems when they already have a nano-sim and just plunk it in the new phone. This might indicate that they already had a strong signal from the get go. My old HTC One + get's a better signal than the Sony in the same locations with the same (new) SIM. With the Devilcase bumper on it gets 5% less. My very limited tests yesterday seemed to indicate that it was signal strength related. I am not enough of a conspiracy theorist to imagine that AT&T would program their system to not function correctly with sims that are provisioned with these Sony phones which they are obviously ignoring for some reason. Or am I?
I had all kinds of problems with the Z3 on AT&T. The IMEI caused an issue since AT&T linked it to a flip phone and therefore couldn't provision LTE. I changed it to an old AT&T LTE device and then I was able to get LTE but was having the same issue with calls going directly to voicemail and texts showing up hours later in bunches. I found the solution was to switch off LTE in the quick settings menu. All calls and texts came through and on time while LTE was off. If I needed a data boost to stream, I turned it back on until I was finished streaming. This was while on KitKat. After upgrading to Lollipop, I was able to keep LTE turned on and calls and texts still arrived on time.
I use data rarely. Mostly wifi. If I don't leave LTE on, my phone reverts to wcdma preferred. And why can't LTE just work without me having to constantly turn it back on? What bugs me is having the APN settings greyed out. I want to be able to turn it off. If anything it seems the phone itself is preventing me from accessing the sim. It feels like I'm borrowing something which contains lots of MY private data. I know my phonebook is stored locally but I also noticed there is no option of specifying the sim or not. Anybody know how to switch APN on and off? In fact, overall even rooted, I still feel like I have almost no power over it. I can't even disable the cellular connection without going full on airplane mode and I do not trust that. I don't even fly so that needs work for sure. Dumb question but could I buy a working nanosim from say 7-eleven that my apn switch will work with?
"Anybody know how to switch APN on and off?"
On my Z3 on OTA stock Lollypop I have an icon in quick settings to turn LTE on and off. Drag two fingers down from the top of the screen. If no LTE icon then select the pencil icon at the top and select the LTE icon. There is also a mobile data icon switch there.
To turn off your radio completly you can get the Advanced Signal Status app and select additional info at the bottom and click phone information and turn off radio. Probably a number of ways to do it but that is one.
Sim contact storage was a way to move information from phone to phone. You can still do it but not really necessary with cloud backup and storage. Google does it for me without me having to do anything which I like. I still save contacts to the sim just because I can. Export and import in your contacts app menu.

Works fine here. I don't pay attention to the dBm estimates since these aren't measured with calibrated test equipment and vary widely. Those numbers are basically worthless.
The only valid comparison is data performance in a given environment (ideally a difficult weak-signal one) - and at my desk with very weak signal, every phone I've ever used performs similarly to the Z3.
"Those numbers are basically worthless."
True, but we have narrowed this down to the possibility that it might be signal related so it is worth a shot. If people whose phones are working fine would measure the LTE dBm on Advanced Signal Status at the location where their phone sits and works well the most we might possibly see some measure of difference in the phones that are not working. Most of the non-working phones seem to work sometimes so signal strength is the next best parameter to rule out. Thanks!
Here are the screen shots of my phone with LTE on, LTE and wi-fi and LTE off and wi-fi.
How do the working phones compare? Does your CDMA (voice) also go to 0% when LTE is on and GSM = n/a?
Thanks. I think adv sig nfo actually works. I'm amazed actually. I can't find the phone's native greyed out apn switch anyways which really makes no sense.

Sprint Galaxy S8 - is phone and web at same time possible?

Does Rooting allow phone calls and web browsing at the same time on Sprint Galaxy S8 ? Is the phone capable of this. Does it have enough/the right radios?
No, current Sprint phones do not call and data simultaneously over 3G or LTE, including the S8. Rooting has nothing to do with it.
please explain
OK, you say rooting has nothing to do with it. How does an Samsung phone on Sprint prevent concurrent data and voice on LTE when Samsung phone on Verizon allows concurrent data and voice.
It has to be hardware or software on the phone or the network that prevents this.
Is the hardware inside the phone the same which suggests to me the phone's functionality is "throttled" by the phone software or by the network itself, hence my question about whether this can be overcome via rooting the phone.
You apparently can get free hotspot through root, why not call + data?? If you can't I'll accept the reality (I am not looking for alternative facts), just that your answer was insufficient to persuade me that my logic is wrong.
Thanks,
Paul S

Sprint doesn't have voice over LTE ....yet. Apparently they are working on software solutions to whatever their network issues are. Found this post from about a month ago on the sprint community site.
Sprint is excited to announce a new solution which allows customers to use voice and data simultaneously while on the Sprint LTE network or WiFi. Calling PLUS has just been enabled on the Samsung J7 Perx, with more devices to receive the update soon!
What you need to know:
Calling PLUS combines two features: one old and one brand new!
WiFi calling - our VoIP calling feature that lets you make and receive calls over WiFi
Voice and text on the Sprint LTE network, allowing simultaneous voice and data
Calling PLUS is delivered to your device by software update. Once your device has received the software, set up is easy!
On the phone, select Settings > Calling PLUS.
Slide Calling PLUS to On.
Customer can view Tutorial pages to learn more information about the service.
View pre-populated address
If the Country field says Non-USA, Select the Country and choose USA.
Enter a USA address manually.
If address is not shown or is incorrect, enter the address manually.
Address must be within the USA.
Select Save.
Your phone will validate the address required for E911 service and completes the enablement of Calling PLUS.
Select Calling PLUS options to enable each feature:
Wi-Fi Calling is On by default.
LTE Calling is optional but recommended to allow both Simultaneous Voice and Data and call handoffs between Wi-Fi Calling and LTE Calling.
Call handoffs will go from Wi-Fi to LTE even if the LTE Calling switch is Off. LTE Calls require the Wi-Fi Calling switch to be turned On for a handoff to Wi-Fi.
That's it! Your phone is now enabled for Calling PLUS. You can call anyone using Calling PLUS, the person or party that you're calling does not need to have Calling PLUS in order for it to work.
Keep in mind:
Calling PLUS is included free of charge with your Sprint plan, though data usage does count toward any metered data allotment.
Calling PLUS is a only available to select devices at this time and only in areas with LTE service. We will add more device models over time.
Calling PLUS is not a VoLTE solution and call quality can vary based on location and network conditions.
Calling PLUS is only supported on the Sprint LTE network and will not work over roaming partner networks.
Calls initiated while on LTE will not hand off to CDMA towers. When leaving an LTE area, such a call may drop.
Have questions about Calling plus? Ask us here! Have you received the update on your device? Tell us how it's working for you so far.

How to Use WiFi Calling

I've posted about this throughout the board, but I figured it would be better to make a thread since everyone keeps asking about it.
You'll need to install Google Voice and Hangouts Dialer and set them up. That's it. Just use the Hangouts dialer when making a call and it will do it over WiFi. If you wish to have people call you over WiFi, they'll have to call your Google Voice number.
This is a workaround, so you will be dealing with two numbers. Your carrier assigned number and your GV number. In my GV settings I have chosen to use GV for all calls, now I just have to get the number out to people. The other option is to port your current cell number over to GV, and then you won't have to notify anyone.
The VZW signal at my house is terrible, so this is what I do, and I can tell you it works perfectly. Hope this helps some of you with poor wireless reception.
Cheers.
This works so well, and I love the features that GV offers, call screening, texting from your computer, etc, plus the fact that I plan on buying unlocked phones going forward, that I decided to port my number over to Google Voice. Now it doesn't matter if the phone I buy supports my carriers WiFi calling or vice versa, and I'm only dealing with the one number I've had for years. Couldn't be happier.
Yeah, I just called ATT for help provisioning my daughter in law's replacement iPhone and while I had support on the phone I asked them about Wifi Calling and she said that our phone is not on the BYOD list for wifi calling. She said that very few phones are, it;s pretty much the iPhone 6 and 6s at this time.
Which is weird, because wifi-calling isn't even going through their network. That's the point of wifi calling, that you are using your phone on someone's wifi, so why does AT&T even give a rat's a$$ if you do that? So weird...
So if my network provider has WiFi calling as part of my deal as standard will it work without the work around?

If Wifi calling shows up in the settings menu, you should be all set, and won't need this. However, if you're on Verizon, like me, or AT&T like the poster above, chances are it's not showing up in your settings menu. So, if you want to make calls over Wifi, this is the way to go.

I'm on Verizon so I can't speak for AT&T, but in my case I don't have the option in settings.
Frankly, I don't care about Wifi calling except for that once or twice a year I am both out of cell coverage, but somehow manage to have wifi and need to make a call. With unlimited minutes and data, the need for wifi calling is pretty slim, but it would be nice for that once in a blue moon where you do.
I don't see why AT&T has to "support" the one feature that doesn't go through their network anyway...
After using Google Voice for free home service for about eight years now, I've also gone all in with it on my cell phone. I ported my cell number over to Google Voice, so I don't have to alert anyone of a number change, and I love all the features it offers. I can make/receive calls from my cell, computer, or home phone ( my Wifi ONLY tablet, too, if I want). All using my cell number. The lone home phone will receive calls to both our home phone number and my cell number. Texting can be done from my cell or computer. It offers call screening, call recording, conference calling, visual voicemail, and do not disturb. Finally, it makes all my calls as VOIP (internet) calls. So as long as I have a data signal, be it from my carrier or WiFi, it makes crystal clear calls. I absolutely love it. I wish I had made the switch years ago.

This is Voice over IP (VOIP), not WIFI-Calling. WIFI calling is when your phone can seamlessly transition between cell network and WIFI, so you can receive network calls over wifi.

no wifi calling and voLTE on three on HTC U11

is there any way of getting this, three says its enabled, I see its available on S8 and people are using it, but seems like HTC U11 is neglected
On Three UK
WiFi calling only works if you're on a reasonably good 4g signal. In call settings, at the very bottom you should see "enhanced call service" with options "voice over lte" and "wifi calling". Enable them.

Huh? lol
This is SO wrong. WiFi calling is for people who are getting a bad signal over the mobile network. If you had a good signal, why would you want to call over wifi? If you have a limit on your account for voice calls, wifi calling will still count against that. It's not VoIP.
Okay further to this, I tried H3G rom on htc and US unlocked ( i have S-off).
Dont find the option of enhanced call service. I believe sim has to play part in that, as when I put this sim in oneplus 5T it did not show enhanced call setting but when i put EE uk sim settings magically appeared
Now I am making calls on 4G so i take it its VOLTE its working on its own. dont find option of wifi calling in rom itself
I had essential phone for couple of days, it had wificalling activated on the same sim and no VOLTE, such a shame. i cant have both in single device
