Has anyone ever lost data connectivity after receiving a phone call?

I've had this issue occur several times. It's not 100% repeatable, but occasionally I lose 3G, 1X and all data connectivity after receiving a phone call.
I do NOT have WIFI enabled when this happens. I've seen posts referring that issue.
When this happens the only cure is a full power down reboot. Toggling Airplane mode doesn't work, infact it just hangs trying to toggle the mode. Toggling Mobile Network in settings doesn't work either.
I've seen this problem since the very first 2.2 leak on 7/27. I've also seen this running Virtuous 2.0 rom. I don't think this is ROM related, rather a generic 2.2 or radio issue (I've seen this happen on the 2.05 and 2.15 radio)
This problem seems to happen in low signal conditions.
Any ideas?

That's how it is with Verizon CDMA, no simultaneous voice and data. There is a network upgrade they can apply to correct it and give them more efficient use of bandwith as well but I guess they are not interested. I hear they are going GSM in the next few years anyway.

I didn't mean to imply that they work at the same time. I meant no data connectivity after I hang up.

Oooh. Well I've had 3 of these phones now and I have had that problem also. Verizon told me to update the network by calling *228 and choosing option 2. Seemed to help.

I wonder what that has to do with it. I thought that had to do with roaming which I wasn't.

I think that's mostly what they say first for any network problem.

It sounds like you have an app that is fouling your data connection. Do you have any third-party phonebook/contact list apps? I'd look there first.
As for the *228 Option 2 (or the PRL path for your carrier), that is standard telco procedure for "get off my phone, I want to go back to having my thumb up my backside." All it does is update your Preferred Roaming List.
You could try Option 1 or 3, which are programming related, but if your rep tells you Option 2, do not lie & tell them you just did it. VZW's system tells the rep the last time you did - including the date of your activity. However, you can snicker, knowing you got a loser rep.
Warning - listen carefully when using O1 or O3. Let it repeat the instructions if you're not 100% sure, else you will be calling tech support & possibly getting one of the losers. Or, you could get a gem. BTW - O3 is hidden - you have to trust it is there.

No third party apps like that. I have tried option 1 and 2 but I didn't know about option 3. I'll give that a try. Thanks.

Questions on using Samsung unlocked S8 on Verizon

I have read a bunch of threads all over and done some searches but cannot seem to find any clear definitive answers on a few things. I am looking at grabbing the Samsung unlocked S8 and want to know for sure if anyone can confirm what does and does not work on VZ with that model? I am pretty sure of the following, but anyone who has one on VZ and can help me out would be greatly appreciated.
- WiFi Calling does NOT work on VZ with the unlocked version. I am pretty sure based on what I read on this.
- VoLTE and HD calling DO work on VZ. Again, pretty sure from what I read but it is hard to find definitive answers anywhere.
- Any app based WiFi calling would still work (so using stuff like Signal or any app that uses data to make calls could make WiFi calls even if the VZ network WiFi calling does not work?)
- Video calling DOES/DOES not work? Cannot find any answer to this.
- Voicemail still gives you notifications/works like normal? I think I read someone say that Visual Voicemail does not work, so the app that lets you just tap and see and instantly listen to VM would not work and you would have to dial *86? Not sure here and clarification is appreciated.
- Any other significant issues or things that don't work or are affected that I have missed?
I think it is pretty bad that phones can evolve with tech and you can get a phone several years and models newer than an older phone, but because one is carrier locked version, it has a ton of features that the newer phone can do, but won't because of carrier BS. Again, all help is appreciated. Thanks!

Visual voicemail does not work. HD calling works. I dont do wifi calling. I dont do video calling. I have unlimited data and mobile hotspot works flawless.

Did you decide to purchase the unlocked S8 for use on Verizon? Has it been a good experience? I'm thinking of buying one since I have the grandfathered unlimited data plan and I'd like to be able to use the mobile hotspot without having to root. Although I don't travel too much, having the option to use my phone in another country by popping in a local SIM is definitely an attractive feature. Thanks in advance!

Verizon Essential stuck in 3G after the upgrade

Before I updated via OTA to 8.1 the Essential was connecting to LTE without issue. Since 8,1 I have to connect to CDMA and 3g in order to user my Dialer, otherwise Server Error is generated. No calls in or out.
I wanted to downgrade Yes rebooted, factory reset, etc.
I searched google up and down with no real answers that work. How do I get Sideload working again? It has to be a simple configuration or driver problem I will assume.
Thanks

Im in the same situation you are in also im on 3g at 1.50mbs up & down i have searched every where....

I wrote that post that he referred you to, and while it worked in Oreo 8.0 it does not seem to work in 8.1 for me either.
Try this:
dial *228 and get a PRL update
reboot
*#*#4636#*#* (it may take a few seconds for it to come up if you do it right after a reboot)
set it to LTE/WCDMA
reboot
(you may have to check in mobile network settings that your APN is set to VZWINTERNET)
Let me know how it works out for you. I know that Verizon doesnt support WCDMA, but it forces you over to the Verizon LTE bands which is more or less the goal of this. For some reason this functions differently than any of the other settings that include LTE in them (believe me, I've tried them).

Well I reset my PRL via *228 and sure enough selecting 4G/LTE does put us at LTE/wcdma but my phone functions perfectly. I do notice the menus are changed and I got a couple other options though now. See attached

Yep those are how the menu should look for a device that's not locked to sprint. It seems to me there are some firmware files that prefer sprint in these beta builds, because even on other carriers (and more than one person has said this) you can see 'sprint' pop up in the bar or in the settings even when you arent on sprint.
Interesting that yours gives you the option of 'wifi calling provisioned', I cant get that to not be greyed out on mine.

Yeah I've screwed with this phone so much I don't know what I did LOL but now it shows wifi calling even in dialer. I'm not sure if it really works cuz I have a good signal so it never switches. My e911 address is set up from my Moto z and I do have a wear24 watch tied to this phone not sure if that's what triggered it. ? I did get a new SIM card on Monday as well because I was fighting with the vzw crap so I don't know exactly what triggered the WiFi calling.

Thank you for the steps but still cannot use 4G for phone calls, but it does work for internet, facebook, email,etc.
Have to go back to 3G for phone calls.
Very interesting why it happening and not widespread. No special configurations or setups on my phone.

That's where I'm at too... the one thing that might be different about this is I tried my old steps first before figuring out how to get it to work with these new ones... seems like a lot of effort, but it might be what is needed (or some amount of it) to get it all working. So try going through the old ones before the new ones (you probably dont need to *228 again since you just did)
My old steps linked here (these worked in 8.0, if they work for you in 8.1, more power to you, but they dont work for me):
https://forum.xda-developers.com/showpost.php?p=74920423&postcount=506
I'm still routinely messing with it because I feel like the setting I have now prevents me from falling back to CDMA if LTE is unavailable for some reason. Fortunately that is a rarity for me... but I maintain that Essential has something in the ROM itself that is preferring sprint and I think it's screwing with us using Verizon.

There is something there.
I've done that procedure.
If I go into the menu and play around it will try to connect to sprint even with a Verizon SIM. Go figure?

Exactly. If I leave it on certain settings it'll actually sit there and tell me I'm connected to Sprint.

I just reported this to Essential in their beta feedback.
Others should report their similar issues.
It seems to be associated with them making a unified release.
If you look at some releases they are specifically for Sprint or Not.

Try turning off Enchanted 4G LTE Mode. It's possible going to 8.1 just reset this setting to on. This should only be on if you have HD Voice enabled on your line on Verizon (you'll have to call Verizon to enable it, it's a free feature).
This should fix server error on 4G, randomly connecting to Sprint is a separate issue.

UPDATE Now working
Took the advice from someone on Reddit who had the same problem. Ran to VZW store and received a new SIM. Without any programming on my end or reboot, back to LTE without issue. FINALLY. As soon as the rep popped in the SIM the essential connected on its own.

Just wanted to second this post that a new sim card is the key to solving this issue. In my case, I was using Red Pocket CDMA (VZW network), and I ran into the same problem. Red Pocket rep explained to me that my sim got provisioned to 3g only and that I needed a new sim to connect to LTE. As soon as we switched to a new sim, I got LTE. I hope this helps others.

Phone no longer ringing when the network is 4G LTE

Using the phones on Sprint.
Since three weeks or so, while on LTE, the incoming voice calls are going directly to voice mail.
Sprint looked at it and changed the Network to 3G and now getting a ring for the incoming calls.
Basically, I am forced to run the phones on 3G service.
Need to go to a service center (which is very far for me) to have the phone looked at.
Anyone facing similar issue?
PS: 2 of the 3 PH-1 phones I have, are having the issue.

Google have updated the dialer recently several times, could it be a bug that shows on Sprint, or do you have spam settings on, which I know has caught other people out. Check/play with spam settings in her dialer app.
(other areas I might check (if not dialer or network). I assume all phones were working before correctly, right? Are they different sims or the same sim in different phones? New sims, ie not old one you have cut down hat are old spec. Do lte settings match on different phones?)

Same issue. Did you get it fixed?

I also have this problem on Sprint.
Sometimes restarting the phone fixes the issue, sometimes it doesn't.
Between this and no longer being able to use Google Voice without using a separate number, I think it's time for me to bail on Sprint.

My wife had this issue a bit back. Only happened when the phone was using VoLTE (verified by a debug menu, *#*#4636#*#*, showing both voice/text and data marked as LTE).
Fix was to disable the Enhanced 4G LTE communications option, which forced the phone too fallback to nonVoLTE while still using LTE for data. Again confirmed using the phone information menu which showed voice as 1xRTT and data as LTE.
Hope this help and that we can get a better fix soon.

Didn't work for me either but I figured it out... what I had to do is change a setting under Google Voice in Settings under the tab CALLS change to "Use carrier only" and I did have to turn VoLTE off. I left the Preferred network type as LTE. Phone is working well now, with T-mobile and Google Voice I have been testing it all morning.
:highfive:

Any fix for no data while in a call??

I realized while in a call the mobile data is gone which might be normal perhaps because it can only handle one thing through the modem......
I'm not sure, but just wanted to know if its not normal then anyone found a fix?
Thanks

Depends on the carrier, which carrier do you have?

Sounds like you changed settings to LTE only to force VoLTE without carrier support. That would be the behavior to expect under such circumstances. Not saying you did btw.

Thanks but no, I'm not forcing lte as there's no Volte here.
If there was then the problem wouldn't exist as those calls would go through mobile data and in that case the data wouldn't be cut.
Again, from what I've read around it really has to do with modem not being able to support 2 things at the same time like call (regular) + mobile data.
I just wanted to confirm more people are having this and that this behavior is kind of expected and not a glitch. As generally I have WiFi on I had never realised this until yesterday that I had WiFi off and was on a very long call and realised I couldn't access the Web at all.

Did you ever find anything out i'm experiencing the same thing?

In my experience (not with this device) if there is lte link when placing a call, the data would fallback on 3g network. If no lte, there will be no data at all

And you're right, it does depend on carrier, however OP never told us. Lol. My brother has US Cellular and there is no data while on voice calls. That's just how their network is.
