T-Mobile MVNO -- Cell signal drops still in 4.4? - Nexus 4 Q&A, Help & Troubleshooting

So by unhappy circumstance, it appears as though the MVNO-related radio bug (which causes your signal to essentially drop out at random if you're using a Nexus 4 on Android 4.3-- and now 4.4) is back again, and with a vengeance. I've tried running most of the radios out there (back to .27), as well as several hybrids, but my Nexus 4 on T-Mobile keeps dropping signal every few minutes. I thought at first that it might be an Iowa thing, but it's not-- toggling Airplane Mode on and off a few times usually restores signal link and I can take a crystal-clear call.
Anyone know of a radio or settings patch that might put an end to this? Tried reseatting the SIM but no joy-- I'll be taking another crack with that method soon enough. I've also tried adjusting radio settings, but that's also a solid no-go for me as well. Any help would be appreciated, even if it's just an idea. Thanks folks!

Not that is much help, but I have the same problem....but only at my work. Generally everywhere else I have been I can at least make/receive calls and texts. But I'm at work and only have 1-2 bars of Edge at my desk, it will drop in and out of coverage completely and like you said, will normally take toggleing airplane mode to "wake" back up. But Seriously, this is the only place that does it, I could see if I had Zero coverage, but why does it show 2 bars, make and recieve calls, then have nothing without moving the phone location at all. I went to a .27/.84 hybrid today, have tried a .33/.84 and a strait .33....all have the same results here at work.

Also note, I'm using the $30 5gb 100 min plan to test the network before switching, are you saying that normal Post-Paid T-mo service doesn't suffer from this, only the Pre-Paid or MVNO?
Justin

I'm using Simple Mobile from TracFone that runs on TM here. Never had this problem. I've used .84, the .33/.84 hybrid and the new. 97 radio. The only issue over run into is having to manually configure my APN settings.

[Q] Nexus 4 drops mobile network randomly

Hi Guys,
I recently switched from the Nexus S forums to the Nexus 4 forums
I'm loving my N4 so far
Perhaps too much, because I've been ignoring a problem that I've been facing. My phone drops the mobile network for a few seconds, once in a while.
I was able to find a way to replicate it. I think this happens when the N4 tries to switch on data on 3g or H.
To replicate this,
1) I installed the Network Signal Info app(can't post link here )
2) Next I tried to switch off wifi. As soon as the wifi is disconnected, the phone tries to connect to mobile data network and my phone disconnects completely for a few seconds. See attached screenshot for logs.
Anyone else facing the same issue?
Thanks,
Spaccount
Note that I can't replicate the issue every time. However it does occur very frequently if you first keep it on Wi-Fi for at least 10 minutes.
Thanks.

Note that you need to be on wifi for alteast 10-15 mins before this works..
I tried loading the browser to show the problem(no network).. but I also get an error if I try calling or texting..
Can someone please try to replicate?
I'd like to know if this is an isolated hardware issue. I just finished 2 weeks on my phone.. Hopefully I can get it replaced
How long is mobile data disconnected? You do know that if you are on wifi mobile data is disconnected on all phones, it reconnects when you either turn off wifi or go out of range of the wifi network. It will take a few moments for it to reconnect to mobile data and vice versa, its not an instantaneous reconnect, it can take 10 seconds or a minute or two.

you are correct!
However, during this time period(as in the video), I'm completely cut off. I cannot even send a txt or make a call.
I didn't demo this because I wanted to keep my call list out of the video.

Okay I see what your talking about now, I had removed Network Signal Info off my phone and just reinstalled it. And no my phone doesn't totally drop signal, it drops but not by much when it switches from wifi to mobile data. Are you on stock or custom ROM or Kernel. Its like your radio is turning completely off during the switch to and from wifi, If your on a custom kernel I would suspect it to be the problem. If not then it might be a hardware issue.

Happens on my iphone 5 on t-mobile when is goes from edge to 3g or 3g to edge, I think it's cause of the phone switching the bands

Interesting! I'm on t-mobile as well.
I just did a factory reset(the google lady told me to) and I still have the problem.
Is there anyway that you can get hold of a Nexus 4?
Also where are you based out of? I'm in Ohio. Not sure if that matters?

So maybe its a carrier issue, I'm on ST AT&T. You on T-Mobile by chance? I had signal issues when I had them and dropped them in 2 weeks. Could only get a weak signal in my living room and then would get no network detected in my bathroom 10 feet away.
Okay not sure what caused this but I had my phone off for about 20 minutes and when I turned it back on to retest it I got no signal, then turned off wifi and signal came back, then turned off wifi and signal remained the same. Not sure if this effects my ability to send/receive voice or text. Its probably just the phone saving battery by turning off the cell radio.

I am on t-mobile.
However the network is OK around here. It would be great if someone on t-mobile and N4 can try to replicate this.
I had this issue with my previous defective device. If gps was on the mobile connection would crash. My new device does not have this problem.

I had this exact same issue when I first received my Nexus 4. I thought it may had been a faulty sim card, so I replaced that, twice, same result. I went ahead and formated the phone back to stock, same result. Checked and made sure APN settings were correct, same result. Contacted T-Mobile, they reset my phones service and the data in my area, same result. After both I and T-Mobile ran out of ideas I decided to contact Google for a replacement. Turns out it was a faulty antenna and my new device has been working fine since.

Thanks for sharing this!
I just called google and requested a replacement.
The lady said I should get an email in 2 days. I'm on day 13, so I'm cutting it close
Also wanted to add that I ran the same test(as in the video) while on a phone call. It dropped the call and locked me out of the network for 10 seconds just like in the video.
I logged to XDA to report this issue it so annoying and the biggest proplem that my N4 seems to stuck on 3G and won't open internet untill it connects to H
it also happens when connected to E as I dont have 3G coverage over there and it also drop many times
mine seems to cut the radio off for seconds

Based on the following link, this might be a software issue. I know the issue described in the link is not exactly what I experienced, but is similar in some ways:
http://code.google.com/p/android/issues/detail?id=40514
It's supposedly fixed in 4.2.2
Will let you know if I get the update before I RMA(don't want to force the update).

So this is a hardware issue.
Thanks for all your help with my questions!
Similar problem on Galaxy Nexus
Hi all,
first of all, I know that there's a different forum for the Galaxy Nexus, but since I have a similar problem as discussed here I thought maybe someone can help...
I also have random disconnects from my mobile network, but since I almost never use WLAN it might not be the exact same problem as discussed here, right?
I'm running cm-10.1-20130416-EXPERIMENTAL-maguro-gerrit-35930.zip, and - as I said - my phone randomly disconnects (shows the "no signal" sign in the status bar) and relatively quickly connects back to the mobile network and everything works like normal. The whole reconnection process takes about 5s or so, I don't have to re-enter the PIN or something...
Any ideas how I could figure out what the reason might be?

[Q] Any tips to improve connectivity?

Even on MJ7, my Wifi and LTE connections are unreliable. This is really my only issue with this phone now, and it is very frustrating. I'm showing a pretty consistent 3 bars/-95 dBm, and though calls and texts work great, I get awful data performance. I never had this issue with my last phone on Verizon (Galaxy Nexus). On the wifi front, it just randomly dies, even just a few feet from the router. I'm not convinced that a replacement phone is going to help matters...
Any ideas? I'm about to the point of ditching this phone for a different model...
same thing here. WiFi sucks, even with a strong signal I.e. in the same room as the router. I'm not noticing it as much on LTE, but then again I'm not using that as much anyways. Even as I am making this post, the "WiFi connection is unstable" just popped up, with a full signal showing on WiFi.
I also have same problem. Wifi unstable issue happens when my note 3 have no reception. Some post says delete cache from recovery but didn't helped for me. Some post says if you have adaway then you will have similar problem. Also turning off Auto network switch option from Wifi Advenced option will help too.
But none of above worked for me

The culprit for me was AdblockPlus. After uninstalling, all "Internet connection is unstable" messages went away. I am now using Adaway with no problems.
On a hardware level, the best i can think of is to add one of those sticky antenna boosters on back of battery cover but didn't try it yet
On a software level, i imagine that there must be some android equivalent to increase the tx power of the antenna, but not sure how
Hopefully someone can chime in with something concrete since many of us are having weak data coverage in major cities
This might be a contributing factor to our slow LTE speeds: Verizon's CFO admitted that VZW's LTE network in big cities is "strained". I guess the good news is that it should get better by 2015...
Certainly if you're not in a large city this may not apply to you. I'm in San Francisco most of the day and I can confirm that LTE speeds here are ridiculously low, even with a strong connection I am lucky to get 6-7 mbps download and around 500 kbps upload.
I went to the Verizon store last night, and the guy said to call 611 and report the LTE issue. I'll try that today.
The Wifi issue is super frustrating. I'll be in the middle of the most mundane things, and the connection just drops, making me wait a minute or so while it reconnects.

I'm not even in a major city. I'm getting speeds like 0.10 mbps where I work, completely awful. I'm leaving Verizon altogether if they can't do better than that. I know that this spot is not the norm, but it's my workplace. If I need it to work reliably somewhere, it's here.
MJ7 seems to have given me poor connection all the way around. Why verizon put on "improved connectivity" on their OTA is beyond me. Its worse if anything. Most of the time in my workplace I cant even update an app because the DL time is like 10 minutes for a 3mb app. Thats with 3 bars on 3g. Forget about a 4g connection in this building. However...my coworker on ATT has strong 4g even in this building.
Wifi is crap. It will be full connectivity and the in/out arrows lit....STILL freezes on loading pages and stuff. It would appear I have a strong fully connected working wifi signal but it just hangs there and pauses for like 1-2 minutes before even loading a webpage sometimes. Its becoming an extremely frequent event actually. Starting to really bother me. I never had any of those issues on MI9. These folks need to stop worrying about trying to patch up root with updates and causing other problems. Especially since the vast majority of users on their network are NOT rooted.
people dont root to steal from vzw anyway...or take advantage of services most of the time its just to customize their phone...and delete bloatware.
I dont see why they have such an agenda against root. Stupid.
Called Verizon, and they "reset my connection," and asked me to reboot. No change. The guy said the next step is a replacement phone. I doubt it will help, but I suppose if that's what they wanna do, I'll do it :/ I'll keep requesting replacements until they find a real solution...
EDIT: Called again. They put in a "trouble ticket" for the area. Let's see if it helps!
Was on MI9 stock rooted. I ODIN'd the MJ7 modem this morning cuz I couldn't stand my WiFi dropping off any time it wanted. Since then, my WiFi has been pretty stable. No complaints on LTE since I only tried this on a flashed phone (ie no LTE in the first place).
I spoke too soon. WiFi is still dropping off frequently.

For those with LTE issues you might try turning on airplane mode to shut off all of your radios and then turn off airplane mode. I have had to do this many times on my Razr Maxx to reset the 4g radios when it gets stuck on 3g.
Things I've done to try to fix my WiFi disconnect issues:
1) Turn off WiFi power save feature via service menu.
2) Wiped cache and Dalvik cache.
3) Upgrade radio to MJ7 (ROM is Hyperdrive based on MJ7).
4) Changed from DHCP to static IP (as suggested by Samsung via online chat).
5) Turn off Auto network switch.
My very last option...which I've already done...contact Samsung for repair. I'm shipping it back for service.
Now I just need to find a fully stock ROM to ODIN first before shipping.

[Q] No Service after period of time

I have an Australian Telstra Galaxy Note 4 (SM-N910G). I got it today. I have rooted it and thats all.
Twice now, I have just had it on charge, the screen off. When i've gone to use it after about 30 mins or so, it has no service. Nothing I can do will fix it other than rebooting.
Not sure if its a fault with my phone, something wrong with the root or a software issue.
Does anyone else have a similar issue.
Both times its happened its been on charge. I'll take it out with me now and see if it does it just in my pocket.
Thanks

Although i dont loose signal all together i get no data throutput at all after an amount of time i have to enter flight mode and disable it again to work thats with full reception! Im in sydney using boost mobile (telstra 3g) exynos model
Maybe you need to change the network mode to WCDMA/GSM (ie turn off LTE if it's not available).
Tried it no good.. disabled xposed completely and seems to be normal for now.. ill report back if i havr this issue again

Nope same problem again.. hmm gonna do a reflash of stock rom when im home. My guess is software issues
It just did it to me after being off charge for half hour. No idea what triggers it.
Nope not sure but frustrating as hell
Same issue. Have sent phone in for repairs. They found nothing wrong with it. Sent another new Note 4 replacement having the same issues: No service after checking the phone after an hour or so
Oh I was looking for a thread about this issue, mine is sliiiightly different though.
I'm on 4G, but I use WiFi whenever available. I then notice my battery draining 1% per 30 minutes even though I'm on WiFi, when normally it would be 1% per 1+hour. When I switch it off WiFi, the 4G signal never recovered but showing 2 bars of signal (which is normal at where I am). Switching to WCDMA didn't bring back 3G, then switching back to LTE also did not bring 4G. When I call to the mobile, it will go straight to Voicemail as if not connected.
And yes, Flight Mode ON then OFF restored connection.
I'm on stock everything, disabled bloatware, no root.
Network not available after root on Note 4
Hi there, My Note 4 was working fine before root. I used a wrong root file so it stuck on Odin and after rooting with correct file it again comes in working condition with no service or emergency calls or network not available. Its IEMI and serial no. is fine. I can see 4g written near network and 4g works. I can use Internet services but not Call services.
I have tried stock firmware wia kies and Odin. Now using Sweet ROM V7 but nothing works. If I use 2 degree 4g Sim then I can use calling services on it and if I disable 4g then again no service nd nothing on it.
This happened after rooting. Tried different modem files given on Sweet ROM page but still same problem.
Please help me.

[Help] LS997 rooted, DevDigitel rom not getting any service

Hi,
Hopefully this is the right place to post, as this account is too new to post in the dev thread.
For the past few days i have been on the latest rom from this thread https://forum.xda-developers.com/v20/development/rom-ls997-stock-debloated-su-goodies-t3531923 (version 4.0HHH) but i cant get any service, be it 3g or 4g (Sprint, LS997). I can text and make calls, however. I've tried everything i can think of and have been searching frantically for help. A list of things i have done so far, to no avail:
wipe data and reinstall rom
update prl
change apn
update profile through sprint zone app
use shortcut master to try to change apn
flash different roms, such as the one found in the dirty santa thread, none of which work
activating my phone by dialing ##873283# - after a while it said my phone was activated, restarted, but then no service
I have been using an app to check up on which networks i'm connected to, and it always says eHRPD. I don't think the problem is that there are no towers in range, because my family members all have 4g lte.
At this point i'm really not sure what else i can do, and any help would be greatly appreciated.
edit - for a bit more info, when i go into settings and try to change the apn all the options are grayed out. the options are: internet, ota, pam, and vowifi, with internet being the only one with a selection circle next to it. thats why i used shortcut master, which was suggested in the devdigitel thread. when i access the apn settings through there, it has 3g_apn, internet, pam, ota, vowifi and a bunch of dummies. i can select 3g_apn or internet, but i dont think either of them make a difference. when i try to make new apns they dont save and i cant select them.
edit 2 - I went back and flashed the sprint stock rom from the dirty santa thread (https://www.androidfilehost.com/?fid=385035244224409782) and then reset the network by dialing ##72786#, then activated it again by dialing ##873283#, and after a prl update and profile update (while connected to wifi) i get 3G on and off and i had 4g lte (for the first time in weeks!) today out in the city. I think the coverage by my house just sucks, but its very frustrating nonetheless. still doesnt seem like a permanent fix, because 3g is very spotty and 4g only lasted for a little bit
rowing the same boat
i am stuck in a similar rut myself. have you had any luck with the problem, OP?
after a successful root/unlock of bootloader and running the stock rooted rom for a few days, I decided to take the plunge and install a custom rom, after my desire for V4A got the best of me. having had problems with modem signal quality in the past, I am out of habit continually checking my signal level. Before flashing the custom ROM, my signal was around -70 to -77 db .. immediately after clean flash of custom ROM my signal level dropped to -117 and lower. when I do see something show up, it is a 3g icon, and then only for a faint second or less. have yet to see the 'LTE' icon show.
I have tried ##72786#, ##873283#, updating prl/profile. deleted via fastboot : system, fota, misc. reboots, reflashes dirty and clean.
still, i yield a totally undesirable (read: not there at all) signal. i have been using Samsung telephones since the Transformer days (pre OG galaxy) and in a situation like this, one would typically have a modem file to flash via 0din. Is there an equivalent to this for LG telephones? I admit my noobishness with the way of doing things with LG, but i am not unfamiliar with adb/fastboot/0din.
Could myself and OP somehow inadvertantly disable a few bands on the modem? is this repairable?
i realize its anecdotal, but still, my signal took a header immediately after flash of the new ROM (i am hesitant to name it, in case someone interprets it as casting shade at another. ) Could this be the reason? Am i missing something really friggin stupid?
Have you found a fix? I'm in the exact same boat.
Hi there!
I had a similar issue with my LS997 as well - I went through all the troubleshooting with sprint, did everything that you've done including installing the stock rom. I was never able to fix it on my own - I had to go to the sprint repair center that was in town, and they used LGup to restore my phone to factory.
The issue that I was having, was that I had data, but couldn't place calls or send texts. When I tried to place a call, it would tell me that my phone was not activated. Texts just wouldn't send. I spent the better part of two days scouring everything that I could find on the issue, and couldn't come up with a solution. It repeated the issue on every rom, every update, everything. This is all that worked for me.
I've decided to keep my phone on stock until we can get our hands on LGup and a stock kdz, since that is what will resolve that particular issue.
Did you come clean and tell them it was rooted? I may have to go in the store today and do this. The phone is almost useless at this point since I can't receive/send calls or texts.
I did come clean, but I carry the nice 13 dollar a month insurance on it. Also been a customer for near 4 years so that helps as well - I didn't tell the rep that I was talking too, I told the tech that was working on my phone. It's my experience that reps care, techs do not. Especially if it's that easy to fix, roughly 15 minutes or so.
Sorry to hear you guys are having issues.
It seems a small hanful of users are experiencing some service issues
Have you tried to do ##brand#
And let it re-activate that way?
I never activated my test device prior to dirty santa and have no idea how it acted before root.
But after root ive been 100% Lte or 3g 1x depending on area. I did have issues that after any rom flash i do need to do a profile update or a ##update# to return service
To be honest. Lte isnt provisioned by the device at all. Its only provisioned by the lte sim card.
If you ##data# and hit view is your ptn and msid present?
If not this is why texts wont work
For data. Ive found you can use the shortcut master and access all the bands for our handests without the msl.. I can get the msl for those who dont have but its not needed for this process.
You use the shortcut master lite app from playstore.. Then go to search and search mobile network settings. Or lte.
Make sure its set to cdma/lte
As well have you confirmed under your settings you have a network set to lte/cdma?
This seems to get unchecked sometimes..

My personal support tool using hangouts
Ill be busy tonight but most nights im willing to txt call or video and help with q/a and issues.
I'll give what you suggested a try and report back.
I tried ##brand# and it cleared some settings and rebooted but I still have no network. I did ##data# and went through all the settings and neither ptn or msid are present. Phone is set to CDMA on device settings.
I used Shortcut Master (Lite) and could not find a setting to select CDMA after searching for lte. No search results when I searched for mobile network settings.
To add some information, I live in a very rural area where my phone is always roaming. Today I was in an area where I get LTE so I wiped my phone, flashed the LS997 stock rom and did ##873283#. This enabled data and I got LTE but still no text or voice. I wiped my phone again and flashed your rom, went through the same process and got the exact same results.

Make sure its set to cdma/lte
As well have you confirmed under your settings you have a network set to lte/cdma?
This seems to get unchecked sometimes..

I tried ##brand# and it cleared some settings and rebooted but I still have no network. I did ##data# and went through all the settings and neither ptn or msid are present. Phone is set to CDMA on device settings.
I used Shortcut Master (Lite) and could not find a setting to select CDMA after searching for lte. No search results when I searched for mobile network settings.
To add some information, I live in a very rural area where my phone is always roaming. Today I was in an area where I get LTE so I wiped my phone, flashed the LS997 stock rom and did ##873283#. This enabled data and I got LTE but still no text or voice. I wiped my phone again and flashed your rom, went through the same process and got the exact same results.

need to set to cdma / lte
pm me or hangouts.
we need to add some settings, or contact sprint care, ask for your msl, and get your msid, you can manually activate it.
Check in about phone under phone number and min ....I lost both and am going to have to get sprint to flash my phone back to stock also

see here for walktrough, working on getting a way to write a prl manually now. Found a setting to do it but i cant get it to show the prls i have on my device.

lost cellular data

So, when I woke up this morning I noticed my cell signal strength icon was one I haven't seen before. I tried rebooting and toggling airplane mode. I also verified that my sim is working in another device. I attached a screen cap with the icon.
Noticed something similar with mine. I had to turn wifi off, restart to get LTE data (verizon) then turn wifi back on. If restarting with wifi on the LTE data doesn't register.
that didnt work for me
update: had to factory reset, looks like verizon doesnt like that essential ph1 wont take all their bloatware, etc. might have to return the phone if this keeps up
My data connection has also become very erratic - and I've lost voice+data (VoLTE connectivity) wholly yesterday. Worked fine with the activated SIM from my HTC 10 from the 31st to yesterday.. Now, not at all, I've not been able to restore it since.
Really don't want to return it, as I really like the phone, but this has nexus 5x issues written all over it for long term use...
Hoping essential can get a certification and an agreement with Verizon before my return window is over (or at all)..
Pretty disappointed in Verizon here.

Same here, another issue is that essential shipped my phone and within a day i had an email from essential saying that verizon certification is still in progress. verizon will probably not certify it with their system unless essential lets them install their monitoring crap all over the phone.

The Nexus 6P didn't have the bloat and worked fine.
My PH-1 works fine including Enhanced 4G LTE Mode.
What do you have selected for network type?
I have the first one selected because that's the only one that includes the various CDMA protocols, EVDO and LTE.
I see the same connectivity that I had with my Nexus 6P.
i have global selected, as it covers everything the phone can connect to. i had the first one selected but it wouldnt show the lte+, just regular lte. i also have Enhanced 4g lte mode on. it just happened to lose service earlier today. if it does it again, ill probably return it after a visit to vzw

I have the same settings as you, I had functional "enhanced 4G LTE" for the first 4 days as well... That ended yesterday morning abruptly, and I'm not able to bring it back.. There's more happening here.. How long has your device been on the Verizon network? Only a hunch - in a few days you won't have "enhanced 4G LTE" either, even though it'll still be checked, and provisioned for it.

Cellular network is not available
After 7 days my phone won’t make calls I can only use data I’m on sprint and it was working fine until today I call sprint they had no answers at all I email essential no answer now I can only use WiFi calling while home and axx out at work
So, upon further digging I found a place to look at some more in-depth stuff relating to signal stuff. I did some fooling around and switched it from unknown to lte/cdma/umts auto (prl) and it seemed to work after a few moments of time. Though it seems have gone back to t he unknown state again but is working normally for me now, so maybe it was changing states and then a reboot?
How I got to this screen was by punching *#*#4636#*#* into the dialer, and went to phone info
I'm having a similar issue. I often lose my signal. I will have the full triangle/bars but no label of the signal(LTE+/LTE/3G/1x/etc....) and no cellular data at all.
The only way I can get it to return is to restart the device. Happens a few times a day, can't be 100% sure why, but it often appears to be when switching from WiFi -> Cellular only.
I have Verizon, I have had a Nexus 6 and then a Pixel XL for the past 3 years, never once had this issue.
I had constant disconnects and lost of service with my Tmo sim. Tried my Xfinity (VZW) sim and it was great until this morning. Complete lost of service. Airplaned mode on and off, connected to old school RTT 1x.... lol This phone's cellular just plain suck for a lot of us regardless of carrier. Not sure if we just have bad phones because apparently there are those who claim they have great service and connection.
I'm having this problem with Verizon. Seems like if I'm on wifi for a long period it only connects to 1x and putting in airplane mode and stuff won't get it to re-connect to to LTE. Only a reboot seems to fix the problem.

Necro post here but chiming in that I have the same problem with Verizon LTE. Happens when I'm moving long distances in car too. Suddenly just drops LTE and only a reboot will bring it back.

You might check out my post from the Oreo Beta thread... I was having some goofy signal issues early on which I've pretty much cleared up by doing what I mentioned here. Someone touched on it briefly earlier but only mentioned monkeying around with the settings, said nothing about picking up a new PRL.
I state this in that post too, but just in case: I offer this with no express intent of warranty, if you screw up your device, it's on you.

I just changed it from global to LTE/WCDMA and I got LTE back almost immediately. Was weird and global had been working for me for awhile now so not sure what happened in the past few days...

I had, right after writing this, tried *#*#4636#*#*
I set it to global as instructed in another post. The next time I drive a distance in the car I'll have to see if I have the same issue that only a reboot would fix again.
Thanks
I had the same issue and I resolved it a little differently than the previous posters. I turned on adb debugging and logged into adb shell and user-disabled com.redbend.app. This stops the Sprint oma-dm service from running. After doing this I no longer have the issue of my device not reinitializing lte after sleep or 3g.
I have essential on vzw but my only issue is my device won't connect to 4G. If I change network to LTE I get full 4G service but I'm unable to make phone calls. Went into vzw store and they told me you didn't get the phone from us so we cant help you. Day 14 fml
On Xfinity mobile, I had similar issues. Great LTE but sometimes calls just don't work at all. I mess with various settings and it'll work for a bit then so again. Gave up and ported over to Sprint for the free unlimited year which is still probably not worth it. Should've kept with Xfinity Mobile. Lol
