My Nexus 5 has been exhibiting this problem pretty much since I got the phone.
Randomly it will go into Emergency Calls Only mode. Turning airplane mode on/off or rebooting will fix the issue for a few hours but the phone will eventually lose signal again.
I've factory reset - same problem.
I've flashed the google factory image - same problem.
Phone bootloader is locked and not rooted.
It was happening probably once every 12 hours but today alone it's happened 3 times in 8 hours. This does not occur on any of my other 4 phones including Nexus 4 and Note 2.
I contacted Google to get a replacement and it should arrive by Friday.
My question is: has anyone else experienced this issue? I've seen sporadic similar reports peppered here and there but nothing that I can confirm is the exact same issue as mine.
You are not crazy! This has happened to me as well. Google Play bought 32GB white model.
I only noticed it after turning off LTE in a spotty service area. I would still show several bars of 3G or H as if I was connected but my carrier info (Fido, Canadian) would read emerg. calls only. Stranger still, I could receive texts but not send them. Airplane mode on and off fixed the issue, but it would randomly reoccur.
I'm back in a good H+ service area and haven't noticed the issue again.

I'd like to add that I don't know if disabling LTE had anything to do with the problem but that is when I first noticed it.
Posted a reply last night but I guess it never came through
Same here tho my signal would be full bars then the next moment it's gonna have no bars and then showing emergency call on lock screen.... I'm guessing it's the phone problem... Is this a defect?
Well tell us if anything changes with the new Nexus because I don't really feel like calling them for a replacement then unrooting and all of that over again if it's the phone itself or maybe it's just Canadians
i hope this is just a bug coz i dont wanna return the phone coz i already put the screen protector. lol.
happened to me in the morning.... didnt happen again after. but who knows when it will happen again.
It's a double-edged sword. Glad to know I'm not the only one but at the same time it sounds like a somewhat common issue.
Mine also show good signal when this happens. I've never switched LTE on or off so I don't think it is related to that.
I'll keep you posted on the new device. I should receive it on Friday.
maybe this is happening to everyone... thought it mightve been my new sim but i guess im wrong ima bookmark this thread so i can find it on friday ahah
This is a common issue so it probably affects all phones. I also have a problem with not receiving voicemail notifications. Fortunately I still seem to receive calls when it's in emergency mode.
I'm getting a replacement phone on Monday due to black specks on the screen, but I suspect these issues will also show up in the new phone.
I was on WiFi over home's Fios over N router, updating apps - "Google +" as a matter of fact, when it happened, lost connection & just dropped while downloading. Hit "Retry" button & it resumed - unlikely a problem unique to LTE or HSPA (mobile data) signal from the carrier.
Now, of course, mine (rooted, odex Rom, stock kernel & adv. power menu, and no other mods) is optimized for maximum battery life with non-default settings, and Google Now listen turned off, etc. - new T-Mo micro-Sim that's on PAYG voice plan only & LTE not turned on - since I'm still playing with Talkatone app for voice calling instead of using minues.
Keeping in mind that we are pioneers "field testing" the newest 4.4 KitKat OS for Google with this hot selling device - expect an update or patch from them soon ... probably later.
Same problem on a almost perfect nexus 5 no other issues what so ever so I'm kinda worried that my replacement device may have one of those other defects that people are reporting. Fingers are crossed for a software update that fixes this issue so I can reject the replacement device and keep this one. BTW Also a Canadian phone on rogers here

It's quite possible that it is a Rogers/Fido problem.
im truly hoping its a software bug, because i too have this issue. Im on the white 32gb model, with a new SIM also on AT&T.
crossing fingers and toes that its just to it being the new OS's bugs.
I'm on Bell and so far not a single hiccup.
I had the same issue, perfect phone otherwise, RMA replacement is much better no signal loss so far.

I called rogers he said it shouldn't be a problem but he gave me a reset anyways told me to take my sim card out for a little while. I hope this can be fixed because if not its a deal breaker I can't afford to be missing calls and so on. I'm hoping it's a KitKat problem that is fixed with a update

What carrier are you with ?and how long have you been using the replacement phone ?
Sent from my Nexus 5 using xda app-developers app
1. New SIM
2. Worked fine in the T-Mobile store - got 4.4 OTA in the store over LTE.
3. Came home - "No Service" (even if the T-Mobile network is listed, could not register)
4. Call T-Mobile support - Teir1 then Teir2 - Phone is not registering on the network.
5. Inserted the same SIM in the Samsung SGH-T989 - all four bars with H+
6. Back to the store - SIM exchange.
7. Same problem - call Google - Advance Replacement
This is the story, the new phone I've been using for two days without any issues.

Same problem here on O2 in the UK, google sending a warranty replacement out. Only fitted a spigen screen protector yesterday !
My friend and I have the same problem too.
Both 16gb White
What colour of nexus 5 you guys have?
I see some have white, maybe white causes this issue??
What I did was go into APN settings and switch from WAP selection (which it had by default) and put PHONE and I've yet to get the signal drop again. Although now I never see the small H in the signal. Its always showing LTE

This happened to me today. I went into the Access Point Names menu and found my APN unselected (I have only one configured). After re-enabling the radio button everything was fine. Don't know how this could have happened since the phone has been up for a day.
same problem.. didn't see this topic and opened a new one btw..
so you're saying that a replacing n5 will solve the problem?
as what i read everywhere it seems a problem affecting almost all canada's roger and italy's tim users.. so something related to network/carrier/texts/calls..
it happens (to me) after every sms received and even if "emergency call" is displayed, data continue flowing like a charm.. btw if rma will solve this i'll be happy to do BUT i'm afraid it'll be just a waste of time
Hi I currently have the latest Viper installed and I cant tell exactly what causes this issue or if there is a fix but it seems when my phone switches from 3G to LTE or vise versa, the data connection will completely drop and when I go into the settings under Mobile Data it will show disconnected. When I try and toggle the Mobile Data off and on (trying to fix it) it will not allow me and seems glitched. The only work around I've found is to go and change the Preferred network to LTE Mode, which connects but then I have no voice or text messaging. So then I will turn Mobile Data off, switch back to Global Mode, and then all is well in the world until it happens again and LTE switches to 3G.
I wont lie, this has happened on every Rom I have used since trying to update to 4.4.3, LiquidSmooth, Viper, and RKDN which is my current and I cannot for the life of me figure it out? I have tried EVERYTHING trying to remedy this issue from flashing tigers 4.4.3 firmware (http://forum.xda-developers.com/showthread.php?t=2723159) to even flashing back to complete 4.4.2 RUU putting me back to complete STOCK kitkat 1.55.605.2 located here (http://forum.xda-developers.com/showthread.php?t=2727831) and from there accepting the OTA updates to put me to stock 4.4.3 and then reflash TWRP and install new Rom and issue still remains!? I feel I am at the unfortunate point where this may be a defect with one of the radios or something in the phone and know matter what I do, its not going to fix... SO I may need to flash stock RUU and return to VZW and get new device? Which would suck, as I am not sure if there is a root/bootloader unlock method for a brand new M8 4.4.3, Is there? Anyone out there experiencing this?
This sounds very similar to my issue which I created a post not too long ago:
http://forum.xda-developers.com/verizon-htc-one-m8/help/network-issues-t2901138
I haven't tried flashing another ROM yet but I was thinking about it.
Also I tried popping out my SIM Card to see if there was anything wrong with it but it looks fine.

Were you able to change the mode to Global and everything work until the radios switched from LTE to 3G or vise versa? Good to know I am not the only one

I'm not completely sure yet. I just know with the LTE/ Legacy 3GPP mode, I'm basically stuck in LTE. When would normally lose LTE and switch to 3g, It still shows 4G with 1 bar but not be able to do anything. Also phone calls don't work for me in that mode.

Awesome, glad that worked...Thats what I am dealing with. Just hoping that I maintain a LTE connection so my phone does not disconnect where I cant receive calls or text until it's too late.
Well, I guess Im just going to have to take it into Verizon and see if I can get a swap. Must be defect at this point
Does toggling Airplane mode off and on fix the issue? I sometimes get a loss of connection (I've never checked to see if Mobile Data says it was connected or not), and Airplane mode fixes it for me.
Also, the new devices can be S-Off'd, but there's a $25 fee. It's worth it if you get a new device though IMO.

Thanks for that tidbit about the 25 dollar s-off. Forgot about that. SO yeah I will probably take in and get a swap. Thanks
Just got my Edge and switched over from S5. Now my signal just randomly drops. Tried everything, update profile, change sim, reactivate, change roaming to home only, even went to the store. Maybe someone has a fix or the same problem before I try to get it exchange..
I am suffering through the same problem.
Ill have lte for a while and then i lose the signal completely. I had the galaxy 3 and it worked on lte just fine. Methinks the lte antenna doesnt work so good. Sometimes if i go to airplane mode and come back that works other times i reboot. Im tired of rebooting. Ive just lost the signal now trying to type this. If i switch to cdma it is much more reliable but who meeds a 1mb download speed. Iay be returning this phone soon. Such a shame. Its such a pretty phone.

What area are you in? S5 and note edge both use spark so it shouldn't be a signal issue. If you're in an area you got coverage in before, it's probably a hardware issue. Put the same SIM in the s5 and see if it works. That'll confirm it. I'm in Atlanta with plenty of lte and I've had no connectivity issues so I know for sure the edge (at least mine) works well.

Like I said, try the SIM in your old s5 if you still have it. If it works fine on there, it's probably a hardware problem with your note. Get it replaced.

Do you actually lose signal or does it just appear to be very weak? You cannot compare to an s3 as the edge runs on the Sprint Spark network. Spark works well with even one bar of signal in most places (I've gotten up to 5Mbps) and with full signal you can get 20Mbps +.
smh!!!
Ok i bought both the nexus 6 and note edge with sprint....got both in hand right now and neither phone will connect to the sprint network....after talking to tech support for a hr i was told to go to the store which im NOT doing bcuz the store reps have no clue and dont even have the phones in the store yet DUh sprint!.....so im assuming phones to new may have to wait weeks for minor software updates...... C'mon
I was having the same issue since I bought the device at the sprint store. I just kept removing and putting back the sim card till it finally stop. Anybody knows what this software update on my notifications brings?

Well, i live in goldsboro, nc. We dont have the spark network here yet that i know of. We do have 4g lte which always worked fine on my g3. On this phone it seems like i lose the signal a lot ie. Searching for service, webpage not available, sms will send when you regain service. I very rarely get more than one bar signal strength, then the lte turns light grey, then i lose signal. I can usually get it back by restarting the phone or going onto airplane mode briefly and then coming back. Ill have the signal for a few minutes and then lose it again. It was really bad last night but it doesnt seem so bad tonight. I got the phone tuesday so tomorrow is my last day for carefree return. Im not sure what to do. Has anyone else noticed this?
Thanks in advance,

In many, more developed areas, spark will work fine even with 1 bar. In some areas though, you may get connectivity issues due to this. I believe you can call customer support and they can switch you over to LTE if you wish (this will also give you back the ability to use internet while on a call). At least the guy I talked to offered it.
me too
so I have had my Sprint Edge for one day. The signal fluxuates constantly and the data works maybe 20% of the time. Called sprint and working on a replacement as we speak. Went into the store and there was a repair tech there saying he has seen 5 other Edges with same issue and thinks its not the phone but the network profiles and that sprint will release and OTA to fix it. But am returning mine for exchange just to rule out hardware issues
I ended up getting hit with it again but after installing the software update no more signal issues. Funny thing though is I cant find any info on it and it seems I'm the only person who received it.

had the note edge for a day and im having the exact same problem regardless of day or night.. the signal intermittently drops from full to zero bar with red X by it. when there is signal, it is very fast but it just doesn't stay on. i also have a note 3 right now and never have issues with losing signal at work or home. also called tech support and performed update profile/prl/change roaming to home only routine but still losing signal. tech support telling me to take it to a sprint store for an exchange but i don't think it's the phone. any information on that software update RayTrue04? im also from atlanta.

I have no idea what it brought to the table but my issue has been resolved. I only lost signal once right after the update was completed but then it's like something just settled in and no a hiccup so far. *fingers crossed*

Popped up on its own. My friend got the update too but he's still experiencing the signal loss so now I'm not sure what did it for me. The only thing else I recall doing is switching lte/cdma mode to automatic and turning on all the roaming options plus the roaming guards.

Its a Firmware issue
Guys I am almost positive this issue is due to a glitch in Samsungs firmware. I tested the data and was able to download over 1 megabyte per second with only one bar on 4g Spark LTE.
According to the tech support person I talked to that would not be possible on only 1 bar. (btw I stopped the test after hitting 1 Megabyte per second for those that need help converting that equals 8mbps). I was in a saturated 4g Spark network with 5 towers within spitting distance from my location and it still only showed 1 bar. I'm thinking either how the tower reads the signal strength or a bad code line shows no more then 1 bar no matter what.
Now for those having dropped data. Check the Sprint site to see the saturation for 4g Spark service, the phones are now setup to LOCK on and HOLD onto the FASTEST tower, which according to the tech who also filled me in on the way the new antennas work, can lead to what seems to be dropped service. She would recommend for individuals having this issue if Spark service is not fully activated in your area to switch over to CDMA only under settings to fix the LTE data dropping issue. BTW the Spark LTE service is apparently different then the old LTE service so those versions do not appear to work interchangeably (according to the Sprint service map).
I also noticed someone else got the new version of the firmware, which I also have and that did NOT fix anything for me. If anyone is struggling with this issue I would wait until the firmware is updated again. WHICH I hope by that point we can get flashable firmware for those of us that are rooted...???
Now for a VERY Important Fact: there will now be no way to use data while on a phone call. These phones are a single antenna model. You can either be on the phone or data... UNLESS you are making a WiFi call. That is why this is now a option. It will keep the antenna set to the data side of things and make it possible to use data for the internet at the same time.
I hope this helps.

You should have got H960 or H901, AT&T does not allow hotspot or tethering on other networks. Also root of h900 is not available so there is no solution for it. Carrier apps cannot be removed until you root.
LG V10 TMO issue with unlock app
I have bought my LG V10 locked to T-Mobile last week from ebay and when I try to unlock it permanently through TMO unlock app it allways shows the message " Unlock Failed Failure in Processing Request"-
I already reebooted, made hard reset 3 times but it doesn´t change.
Any ideas how to fix this?
My Android is the lastest, original, not custom rom.
You can freeze factory apps without root - just disable them in app manager. As for shaky wifi, that is a known issue with this phone. No fix I am aware of. I am getting rid of mine

Hello all,
Phone: Mi Mix 2S
MIUI: Global 9.6.4 Stable
Model: M1803D5XA
Carrier(s): T-Mobile(SIM1) & Verizon(SIM2)
Issue: MMS receiving is limited to 30kb when using the stock Xiaomi and Android Messages messaging apps. APN settings do not show on device for Verizon SIM(doesn't matter if in Slot 1 or Slot 2).
So I called Verizon and worked with level 2 tech support to try and troubleshoot this issue. Basically, the MMS and/or Device server on Verizon's end cannot verify the device and therefore limits MMS sending to the device as it cannot authenticate. This verification is done by verifying the IMEI of the SIM and the device identification.
So basically level 2 tech support cannot verify the device manually and cannot submit a request to add the device information either, it has to come from the vendor(Xiaomi) to Verizon.
Anyway we can request this from Xiaomi going forward? Seems weird to have all the bands for Verizon, can get full 4G LTE coverage but I can't receive more than 30kb per image.
I had this issue at first. Flashed latest stable and it was fixed. It's fixed on miui 10 beta and its fixed on treble builds

Well I flashed to 9.6.4 stable, which I thought was the latest stable?
I'm flashing MIUI 10 right now...guess we'll see what happens.
*Edit, still not working on Verizon. And now on MIUI 10, Dual 4G is broken.
*Edit 2, now I have Dual 4G back. Verizon needs to be SIM 2, but be the default for Internet....
I'm on VZW only and I'm on the latest MIUI 10 beta. I'm experiencing this as well. My wife receives good quality images from my phone but when she sends from her Pixel XL to me they are terrible. As are images I receive from anyone else. Kind of a bummer.
Are you guys having issues getting connected on Verizon now? I'm not able to reliably connect at all, most of the time it just sits on 1xRTT on VOICE, and won't connect to data. I can get it to connect to LTE/VOLTE by smashing airplane mode or disabling radio over and over again. Occasionally it will go to LTE, but it doesn't stay working and drops out. I can't drive anywhere and even conduct a phone call as that doesn't stay up either. When it drops, it hard drops and acts like the modem is being reset, instead of roaming to a new cell tower.
Edit, forgot to mention, called VZW, they gave me the finger and tried to sell me an iPhone XS Max 512GB as a "suitable replacement" for my 8GB/256GB phone. They were not helpful, and told me that they have "teams taking steps to make uncertified phones not work on Verizon's network for security and safety reasons". I have tried two different sim cards as well, both with active service and both work in all 3 generations of Pixel XL that I have.
Why the hell would Verizon troubleshoot a phone they haven't certified for their network? Quit complaining.

Cause I pay them every month to provide me with service. They could've atleast escalated to someone with a brain and ability to look at logging on their side and tried to help. Your comment was not needed.
I have been struggling for days with my Verizon connected Mi Mix 2s. At times I could connect with VOLTE but I lost my MMS. This past weekend I tried various ROMs with no difference. I finally cleared everything, loaded TWRP and then flashed the Global developer beta.
I also put my SIM back into a phone that Verizon would recognize and reset the card.
When I was up and running again I did the *#*#86583#*#* to unlock VOLTE and then the 4636 dial to set LTE only. So far so good. I was then able to go back and add a correct apn for verizon. With Verizon Messaging app everything is working and stable, including MMS. Afraid to mees with it again. But it is possible to get the phone to work with Verizon.

I have been struggling for days with my Verizon connected Mi Mix 2s. At times I could connect with VOLTE but I lost my MMS. This past weekend I tried various ROMs with no difference. I finally cleared everything, loaded TWRP and then flashed the Global developer beta.
I also put my SIM back into a phone that Verizon would recognize and reset the card.
When I was up and running again I did the *#*#86583#*#* to unlock VOLTE and then the 4636 dial to set LTE only. So far so good. I was then able to go back and add a correct apn for verizon.

Hi - is your SIM a newer (or brand new) SIM? I am seeing something in the logging on the radio logs that the SIM doesn't contain any carrier information, and was also seeing several errors about missing CMDA specific settings. This weekend I spent most of the day on Saturday and Sunday testing build.prop edits, and messing with the apns-conf.xml file settings. I could not get anything other than 1xRTT most of the time (I modified one of the existing entries in the list of APNs to be an exact match of what my Pixel 3 XL has) and by forcing LTE Only in *#*#INFO#*#* I was able to get LTE for brief periods of time, but not consistently. On 8.11.29 and 8.11.23 builds I can't get data working consistently, and if VOLTE isn't turned on, I can't get it to even act like it's going to connect LTE. I checked the APNs and played with it for hours, but not much success. The device just seems to "connect" but if you try to call on VOLTE or use LTE data to do something, the radio appears to reset. I am wondering if someone at Xiaomi neutered something in the RIL setup for their builds that broke CDMA compatibility. When I have time again, I will do some more comparison to see if I can figure out why it's not working. I'm planning on decompiling some of the files in question and looking at the code and configurations to see if something in there is the cause. The radio logs do not have a smoking gun. I also grabbed a copy of the build.prop file from MIUI9/Oreo and I am going to compare to see if they have some kind of prop flags that are missing in the MIUI 10 builds and or PIE builds.
I am going to find a way to make this phone work on Verizon.
Eventually, I rolled back to MIUI9 on Oreo (I don't know the build off the top of my head and the phone isn't near me) via fastboot. I have been able to get decent connectivity with that software version on Verizon where I live. I had to create my own APN, and have been using that with limited success. I submitted a bug report on the MIUI bug reports page. If you want to upvote that bug, the link is here: https://en.miui.com/thread-4724630-1-1.html
Edit: I just went to lunch and couldn't get the phone to connect to anything but 1xRTT the whole time we were at lunch (I didn't force LTE only, as I haven't had to previously since I rolled back). My next steps when I have time is to compare the build.prop between the builds, but I am not expecting to find anything. I am starting to suspect from the differences in the way the logging looks that they may have messed with the code or config information for the the RIL setup in the Android before they built it.
Please keep posting what you try, I'll be following with interest! I had everything working for a while but since MIUI 10.0.6.0 mms has broken.

Can you get data and phone services? Mine won't stay connected, but that could be a hardware problem.

Yeah, data and phone have been fine so far, I think a few times it's disconnected but messing with the APN has fixed it. In general, I'd say my data and phone have been pretty stable. MMS on the otherhand, I had working for a bit on 9.6. On 10.0.4.0 it's been really slow to send and receive or not working at all. When it did work, picture quality was awful.
PS, I have my phone set to Vietnam by mistake. I have an older SIM card, at least a few years.
PS still working fine.
Mine has been repaired, they had to resolder a connector for the antenna on the board and the logic board was dropped. I saw this happen, however, signal levels are as good if not better than the pixel devices in the same spots for me, so I don't think anything is permanently damaged. I've been debating trying to order another Mi Mix 2 from somewhere or ordering a Mi Mix 3. I have built roms and have a lot of android troubleshooting experience, and I can't seem to figure this one out. What I am seeing on my device is that once it is connected, it seems to not want to roam properly. Like disconnecting from one cell causes a modem reset and then it takes a long time to reconnect. I am going to keep working on it though.

So you had a hardware issue? After the fix, which things work and which don't work for you? When I disable VoLTE carrier check, I get the VoLTE symbol, but I can't make any calls. I've been messing with the SMSC, where it seems changes aren't persisting. I can't get mms to work anywhere but the stock app, which sucks because the stupid MIUI stock messaging app doesn't have group mms >.>
I had a screen break due to it falling on a very sharp corner of an object from about 6 inches up. I took it to a phone repair place locally. They dropped the logic board, camera, front facing camera/charging interface board as well from like 4 feet up onto concrete. The person who tried to repair the screen (which I provided the replacement for) did not follow the instructions on the video either and removed the plastic lining bezel from the phone body (you are supposed to remove the screen from the bezel with a heat gun). They had to send the phone out for micro-soldering to re-place and reattach the antenna connectors for the cellular and wifi antennas. They had to pay for that. I know what the phone looks like inside from watching the videos of how to replace the screen. When they gave the phone back, there was a substantial gap between the edge of the screen and the bezel in a couple spots (atleast 3 or 4 sheets of paper thickness). I ordered a new frame, bezel and screen all in one and replaced it myself (moved all the components from the original phone body to the new one). Everything appears to work, signal levels are good, but the cellular part will not stay connected, and the modem acts like it's resetting all the time. Sometimes it will stay connected to the repeater in the office I work in for 8 hours straight with no issues, and I can text and call. When I leave that area or go home, it doesn't seem to want to roam to service, and instead of switching cell sites it seems to just reset the modem. There is absolutely a possibility that some small transistor, resistor, cap or something else on this board got damaged when it fell. Given that you guys aren't reporting issues with your devices staying on the network, I'm starting to think I need to go back and make some serious noise at this repair place. I am no stranger to working on sensitive electronics, and I was extremely careful not to damage anything inside when I moved the components (and it was already exhibiting this behavior when I got it back from them before I took repairs into my own hands).
That said, I've spent the last two days trying to figure out if I can do anything that might be helpful with QPST and QXDM as well as playing with various additional build.prop configuration. Nothing there that seemed to help. Rolling back to MIUI9/Oreo seemed to help some but was not a magic bullet. I still had to manually configure APNs and find myself needing to reboot or airplane mode every time the device should roam to a new cell site. I am planning on trying to copy the "carrierconfig.apk" file that is part of the system settings off of a Pixel 3 XL onto the Android Pie MIUI10 beta to see if possibly Xiaomi has something jacked there, but since you guys aren't reporting issues, I am seriously starting to suspect that something is physically damaged after that drop on the logic board, but the intermittent behavior and the fact that the signal looks correct and normal when it's working is going to make it nearly impossible to identify the cause.
As a side note, there's a Mi Mix 3 on it's way from GearBest....

So on mine, I can't get it to connect whether VOLTE check is enabled or not. At the office I'm like 10 feet from a repeater, and it seems to connect on LTE/VOLTE (if that's toggled on) very quickly. I have VOLTE enabled on my Verizon account. On the extender, I can make calls on VOLTE, but can't call without VOLTE enabled. I can't get it to connect to VOLTE with the VOLTE carrier check enabled, I have to shut that off and manually toggle. I am noticing massive inconsistencies in the configuration information contained inside the carrierconfig.apk that is loaded in the system build by Xiaomi. I don't see a smoking gun there, but there's a metric crapton of differences.
If I am not next to this Verizon repeater, it usually takes multiple airplane mode cycles or reboots to get onto LTE, it just sits on 1xRTT forever, no texts or data come through when stuck in that mode. Any type of cellular roaming that should happen seems to just cause a radio reset, and it goes to blank bars with X and then it acts like it can't find a network to connect to for a while or goes 1xRTT with full bars and keeps resetting every 20-30 seconds.

Cause I pay them every month to provide me with service. They could've atleast escalated to someone with a brain and ability to look at logging on their side and tried to help. Your comment was not needed.

How is Verizon supposed to support a device they aren't familiar with? This post comes off as whiney. Verizon does NOT have to support every phone capable of their bands, that isn't up to them. Way too many variables using an outside device. With that said, running the latest global beta with the sim card out of my Pixel I have zero issues running Verizon Wireless as primary and Google Fi sim as secondary. Both networks getting VoLTE.

I expect Verizon to use the standards defined for how these devices communicate. I expect Verizon to assist with troubleshooting by providing information and looking at logs as to what my device is doing on the network. This is not unreasonable. I am not asking them to tell me how to fix the problem on a device they don't support. I am not expecting them to just suddenly support a device, but I do expect them to be willing to look at logs and information on their side and provide feedback. I am glad to hear yours is working and am starting to suspect mine has some kind of hardware damage. The local repair place has refused to do anything to help out because "if it's got a signal, it's a software problem".

Well, if it worked before the repairs.. it is definitely a hardware issue.
Check your APN settings. I had the exact same issue with my phone, especially after the latest update. I called Verizon for the customer support and they couldn't figure out as well. Then, I pretty much looked at every settings on my phone and tried almost everything, only to have the issue fixed by modifying the APN settings. For some reason, after the update, the SIM card removed the custom APN settings that I added when I first purchased the phone. Instead, it had the CBS, FOTA, IMS, LTE - Verizon Internet APNs available with the APN set as the CBS (Sorry I'm not an expert, so I really don't know what exactly they are. I suspect that those were pre-saved on my SIM cards as I have used the same one for 3-4 different phones?). Anyway, I googled Mi Mix 2s Verizon APN and set it according to the very first result I found. Since then, the MMS has started working well again. Hope it helps.
