[Question]LTE/Connectivity Issues. - Samsung Galaxy A20 Questions & Answers

Let me preface this by first saying, I am using the A20U (So I know rooting to fix this isn't an option. feelsbadman.jpg) But I have an unlocked VZW A20, and am trying to use an MVNO to get data and all that good jazz.
The weird issues is that my LTE (and all of my network for that matter) seems to disconnect it's self about 2-5min after connecting it it. I know it's not a SIM issue (as I've tried this sim in my wife' phone, EXACT same model.) with no issues. I am going to go over all the steps I've taken, as well as the "temp-fix" i've found for it and maybe one of you righteous nerds can help a fellow nerd out...I'm going INSANE.
Temporary Fix : Using "Hidden Menu" app, I can go into the screen and change the preferred network type, (LTE/UMTS auto PRL get's my data, texts, and calls working before dropping off randomly.) I have good signal, and no other issues.
I have XAA/XAA/VZW and Verizon has confirmed that it is indeed SIM unlocked. So I am rather at a loss on what to do. Flashing any files I can find through Odin seems to yield no results for me.
Thanks in advanced! <3

The Ntelos S5

I have an ntelos S5 (G900R7). There is no development for this phone anywhere on the internet. Perhaps I can find support here?
---------
So far (you may skip this part):
I have managed to successfully install Spirit Rom with full functionality, by copying my old build.prop into the system directory, and restoring my previous apn settings using the apnsbu. I forget why I left this rom, but I did. Everything I try has some problem! I then proceeded to try just CM11, by itself, and had 3g difficulties. Then, using Kushman's sprint MIUI, (Ntelos shares sprint towers) things seemed to work right, but it remapped my recent app key to menu... (perhaps I can map it back?) and the volume was not controlled by my physical volume buttons.
-----------
Now my favorite rom so far: Mokee Rom It's fast and visually pleasing, but I have wi-fi and phone difficulties.
After imposing my APN settings, I can reproduce these effects:
(1) Before replacing build.prop, the wi-fi works and can be enabled or disabled as I need. Also, 3g works very well at nice speeds, but it says "Verizon Wireless" underneath the 3g indicator bars. However, I cannot make calls. If I attempt to do so, the 3g data stops working, turns orange, and no longer says "3g". If I do this, then no data can be transmitted or received.
(2) After Replacing build.prop with the "good original" copy (which sometimes fixes similar problems in other custom roms) the wi-fi becomes stuck in a constant state of "turning wi-fi on..." but never turns on. 3g still works, but, as in part (1), it will break if I try to make a call.'' Also, in this case it says "Sprint" instead of "Verizon Wireless"
Does any one have advice, or perhaps some build.prop settings to modify? Or maybe there's a different file that would help. Again, my phone is the SM G900R7. Has someone else with this phone had luck customizing it?
Thank you
nTelos S5
Likewise have a nTelos S5, have not found any custom roms that can successfully be installed without data or phone issues.
Also trying to install any ASOP roms resulted with all phone efs data getting cleared.
Upon searched relentlessly the only rom I found that functions is located at
http://teamcspire.com/index.php?/topic/112-gs5-g900r7-r2-teamcspire-nd8stock-deodexed-101814/
its very stock but functions flawlessly for me.
Advise if you have any luck, I will reciprocate.

My advice is to you, is that if you install Mokee rom, do not update it with OTA update. This is what I think broke the network for me. Even after restoring my phone to factory conditions and using Kies, I still had no network. I ended up going to the nTelos store, where they had to reset the network service for my phone on their end... strange.
Anyway, I have made a few roms work, and I suspect I could make more. If you maintain your apn settings, and build.prop, you should be able to make Spirit rom work. The same thing is true for Miui. However, if I remember from my experience correctly, if you do install Miui, then I THINK you should not restore your original build.prop; it may work without it... just restore the apn settings. When you do this, you may have to change the preferred network mode... I am a little freaked out, after my previous experience with Mokee rom, to mess with this any longer, though. I do have a problem with Spirit rom: if I use the Timely alarm clock, the time panel is miscolored, but I believe that could possibly? be fixed by flashing a different kernel. I plan on flashing Spirit tonight.... stock uses up my battery too fast, and Spirit just feels more responsive.
EDIT: I just re-flashed Spirit Rom, and they fixed the discoloration in the most recent version! Also, as before, my 3g and WiFi work fine.
Took me days...
The CSpire shares the model number and ROM. The US Cellular CM11 is the closest. Somewhere in that I lost my ability to send texts (not sure if it's the SMSC or...) and didn't get it back when I ODIN'd to stock. I would LOVE to have CM support for this model.
I also am in the same boat as you guys. I would love to get another reliable ROM on this phone. I just have bad memories of purchasing my last one (Sprint GS3) from ebay, and having one hell of a time making the MMS work after flashing it for nTelos. However, I never did have to mess with any of the APNs or build.prop settings on that one. I would think the Sprint ROMs should be the closest compatible ROM, being that nTelos and Sprint do share towers in WVa and Va (Sprint actually has zero towers in these states, and leases nTelos towers instead).
Is using EFS Backup by Wanam a good method to insure the EFS does not get screwed up?

You might try saving out your wpa_supplicant file from the stock ROM and replacing it on the flashed ROM. This has worked for me before on my GS3. That might take care of the wifi anyway.
I'm also on ntelos with the s5 now. But it is a us cellular unlocked by them phone. Stuck in a ntelos sim card that I bought from store and everything works. Except 4g. I can live w/o it but it's kinda like a puzzle now. How could I enable this to work on ntelos?
Depending on where you are, ntelos does not have 4G in many places yet. It's still very spotty in West Virginia.
Has anyone taken the OTA Lollipop update? If so, how is it working and does it lock or put in a new bootloader?
I have. It's a little laggy at times, gets really hot when using it while charging and battery drains a little faster. Not sure about the bootloader

I think I will hold off for a while. My stock NK1 is laggy enough as is. Damn, I wish there was a compatible ASOP ROM available for this phone.
Honestly, this Samsung G5 is the absolute worst phone I have ever owned! I would like to get a S6, but my experience has been so bad with this S5, I am almost afraid to stick with Samsung. However, my S3 was awesome!
Just found out that the heart rate sensor is active when the phone is on no matter if S Health is open or not.
I am in the Richmond area on Ntelos. They have stated they have sold their bandwidth to T-Mobile and we are to find another carrier. My phone is not even a year old and no other carrier will activate it. Being I own mine outright and paid close to $600, I am about to lose my mind knowing that I will have a shiny expensive very small tablet in a few months. Has anyone a clue how to change this phone over to GSM or something useful. Verizon refused to even try, though I know when I tried Straight Talk's Verizon Sim it did dial to Verizon's customer service. But Straight Talk nor Verizon would activate it.
Ideas and suggestions welcome.

page plus,i am an ntelos dealer and pageplus dealer i flash phones to and from both companies everyday i am in ruckersville va 12 mile north of charlottesville lemme know if you need help you right its the enitre eastern side of the companyh is gone now to tmobile but you can still activate on frawg..ive done many for customers
Thanks for the info. I am on the frawg side of things now. Their plans were too much when mine ended and I didn't need a phone at the time. Then a few years later, yeah I made my S1 last almost 4 years, I bought the S5 late last year outright. Loved the S1. Made that do everything it just did everything slow at the end.
Anyway, am glad there are options of some sort. Have been reading the reviews of pageplus. What kind of speeds are you getting on it with 4G? Their map shows coverage everywhere which makes me a bit uneasy, as in too good to be true. Is it a simple flash or require editing?
If I can't do something else with the phone, I may try the band opening options. According to the phone specs, it should already have all the Verizon bands but they refuse to activate it due to the meid it seems. I have a feeling this topic may get more viewers as the Ntelos off switch day comes closer.
Google Fit was the culprit for the heart rate sensor staying on. Un-installed it and fixed it
After all this time, has anybody found a ROM that works well on this phone?
can't get data so Internet not working on galaxy s5 unlocked already switched ntelos

In case nobody has seen this, there is a now a CyanogenMod 5.1.1 ROM available now for nTelos. I have been running it for 3 days now and I really like it. Good battery life too. Very stable and very speedy. There are some occasional bluetooth audio stuttering issues, but nothing terrible.

Dropping calls on Tmo

Hey guys,
I'm here because my Mom recently switched to Tmobile and while things do work, she is having an issue with dropped calls. The APNs are set correctly, she has data service, I've set the "network mode" to LTE/GSM so it shouldn't be trying to connect to the CDMA network. What could be causing this? She's about ready to buy a new phone, but I know there has to be a solution to this. The phone works, and granted it's her phone not mine so I can't say for sure exactly what's going on when it happens but she claims it happens ALL the time (7 dropped calls in a single conversation with someone) and I can't imagine why it would/should happen at all. What's the solution here? I'd like to keep her on stock firmware if possible, but if necessary I can either root and/or flash cyanogenmod.
If it were my phone I'd first root, try that, see how it goes, then try CM, see if that does it... but she's not going to put up with that back and forth and repeated wipes. She's just going to get annoyed and buy a new phone despite the one she has being just fine. It MUST be somewhere in the software. I'm not sure if it's trying to switch to CDMA before realizing it can't, or if maybe it has something to do with VoLTE trying to kick in and connect to Verizon.
I'm pretty proficient with this stuff (been modding my Nexus' for years) so I can follow directions pretty easily, but I do need a pointer in the right direction because I can't figure out what's going on with this custom Verizon crap... Thanks!
Probably a non-issue, but is her cell signal strength really low?
We recently did the same thing - moved Verizon S5 to T-Mobile, but my wife has had no dropped calls. Her signal actually is better on TMO than VZW (hence the switch). Our TMO rep set the APN and network mode like you mentioned, so that shouldn't be your issue.
Verizon VoLTE shouldn't be a problem either since you have a TMO SIM, its not even connection to the CDMA towers.

[Moto G4 with Amazon ads] Always losses carrier network after 24 hours

Hello everyone,
I just bought a Moto G4 16 GB with Amazon Ads for my wife, but we are facing a very annoying problem: the carrier signal always dies after 24 hours give or take. We tested with a different SIM card and the same thing happened. When this happens the device only shows "Emergency Calls Only" and we have to reboot the phone in order to get the signal back.
So, is anyone else facing this problem? Is this really a problem with this phone in particular or every moto g4 has this problem? Should I return the device to amazon?
Thank you very much for any information you can give me!

No problems here since I got my phone last week and I have T-Mobile. You might have to check your apn settings with your carrier.

I tested the SIM card in a different phone and it worked flawlessly (I also use T-Mobile). The strange thing is that the phone gets the signal very well during more or less one day, after that I have to reboot to get signal again.
Well, this is probably a problem in the device. I already asked Amazon to send a replacement.

Thank you, but I just use the t-mobile network. In fact, my carrier is called campusSIMs and it is a MVNO that uses t-mobile network. So, my APN configs are a bit different from yours.
However, I didn't know about this mobile data thing. I didn't touch the developer options. Maybe, it can be a good idea.
Thank you!
It won't be your APN settings since that controls your data settings. If the sim is ok then it could be your phone.

I'm seeing a similar problem with the data portion of the network (also on T-Mobile). While I'm able to send and receive calls and texts, data doesn't work. There's no indication that it's attached to LTE or even 3G (just a standard signal bar with no other information). I moved the SIM card back to the old phone it was in and it works fine.
Things actually worked yesterday, so something happened overnight to break it.

That could possible be the APN settings. Although usually it's the opposite, they don't work at first then they update from the network later on. Most times the APN settings will set themselves but on the odd occasion they need to manually edited. I don't use T-Mobile but the APN settings are easy enough to find.

Sounds like you need to manually enter the APN settings. What you describe is exactly what happens when it hasn't loaded an APN.
I'm "kinda" having an issue here. It's a little different though; the phone works ok for a while (for me about 3 hours, usually), and then I still get an LTE indicator, but have no network connection (get errors in apps/"No internet" page in chrome).
Other times, I lose LTE and get locked in 3g (H indicator), and can only get LTE back by going to Settings/More/Cellular Networks/ and toggle preferred network mode to 2g or 3g, let it connect (H or E), then toggle back to LTE.
Motorola responded to a bad Amazon review requesting I post asking for help on their forums.
Relevant link:

I'm active over on their forums also and it's good to post over there in case you ever want to do a soak test. They look at your posts there when they ask for soak testers. As for your problem, I've seen it shift back and forth if you are in an area between towers and one isn't sending out LTE. If it were that I wouldn't think you'd get it back so easily. There's an app, don't remember the name, that will show the towers and signal relative to your location, If might be interesting to look at that.
Having the same issue with radio. Just replied to your post, Kalash.
Ok, we got a new phone from Amazon and it has the same problem. So, I believe this phone does not work very well with MVNOs.
I notice that the problem is that the phone cannot reconnect to the network after losing the signal. For example, if you go to an area with bad signal and, eventually the signal vanishes, the phone will not be able to reconnect to the carrier network. The phone only reconnects after reboot. Airplane mode does not solve the problem.
This does not happen with my Blu Life One X. So, I think it is a software problem.

That's not true on all mvnos' apparently. My wife's phone is on Consumer Cellular, an AT&T mvno and it's never done that. We've been in a no service area several times and it's always connected immediately when getting service back.

[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.

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..

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

im writing a fix now guys, we mamanged to get a work around to manual program your devices.
for some awful reason sprint hid the EDIT option to manually program our devices? wtf..
well we managed to do it a diff way. im making a post now to walk everyone who needs to get their phones active and talk/text/3g back.

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.

I cannot get LTE to any APN work right with any custom ROM on the Moto G4 Play. :(

I have the Moto G4 Play (XT1607) (Harpia) and I have decided to flash LineageOS (lineage-14.1-20170131-nightly-harpia-signed.zip) on it using TWRP v3.0.2 r5. After getting it installed I noticed that it was not connecting to my 4g LTE Internet (I have Ting). So I figured I needed to make some changes to the APN settings. So I go to Settings>... More> Cellular Networks and the moment I click on "Cellular networks" I get an error message saying "com.android.phone has stopped". After reflashing and trying again a few times with the same result, I tried using a completely different ROM. AOKP. (aokp_harpia_nougat_nightly_2017-01-31.zip) and I ran into the same exact problem I was having with LineageOS.
I then tried to see if I could force my way into the APN configuration using an app called "Change APN". This worked, but now I see the message "Access Point Name settings are not available for this user". I decided to ignore this and click on the + to create a new APN. After filling the correct info out for Ting APN, I click on "Save"... and it doesn't save at all.
I decided to revert to the stock rom, and everything works perfectly fine with the stock rom. 4G LTE on Ting works fine. Whenever I try using a custom ROM of any kind, I run into the problem I described above. I don't know if I am forgetting to do something, or completely doing something wrong. I could use some help with this guys.
Isn't Ting a Sprint service? I didn't think CDMA-based networks had APN settings to configure. Verizon and US Cellular have always used *22XXX for programming, as far as I can remember.

Yes. Ting is a Sprint service. Well either way LTE isn't working and the 3G keeps randomly turning on and off whenever I use a custom ROM. However, when I use Stock firmware, everything works perfectly fine. I am unsure what is causing the issue.
It seems nearly all custom ROMs at this point are having data connectivity issues. I'm trying to find a nandroid of the original xt1607 rom so I can just go back until its all sorted out.

With Ting you can choose to use Sprint or T-Mobile. I am using the T-Mobile side of Ting and you do need to add Ting's APN settings for it to work. I am still on factory ROM but watching closely to see what others are experiencing with custom ROMs.

I haven't noticed any issue with my GSM ting service on lineage. I get LTE and the WiFi/LTE handoff seems to work. I don't install many apps and don't let them run in the background, so perhaps there's a conflict between them that's shutting down LTE service. This is just a guess.
Anyone have any information pertaining to this subject? I've searched hours on hours to no avail. I run U.S. Cellular and on the newest RR-5.8.1-OMS after I go to Settings>More>Cellular Networks>Crash. Every time. Resets my radio and picks right back up again. Everything works until I'm in my house, then I'm roaming and there's no way to manage in settings because of the crash.
I looked around in the file system and in /data/data/com.android.phone/ there is no files, no .db files or anything. I don't know of there's supposed to be either. But like OP stated, stock rom is flawless.
Would I be and to copy com.android.phone from stock and restore after flashing? I don't know what to do but this is with every single custom ROM out right now on every release. Data and everything works fine as far as I can tell but just no way to configure the settings. Any help would be greatly appreciated!!!

Just out of curiosity, have you tried the *22XXX thing yet?
EDIT: Just so we're clear, with you all who have CDMA phones, when you go into "IMEI Information," it does show both an IMEI and an ICCID, right? Because if not, I think I figured out why your LTE isn't working.
I tried, I tried dialing *22999 (guessing that the x stood for the 9 button in T9 language) and pressed the make a call button. Am I wrong about the "XXX" part? Because I did try that when I seen it previously in the thread earlier but had the same thoughts.
So to make that novel a shorter version, what exactly should I dial?

It depends on the carrier and the model of the phone. For most Tracfones, it's *22890. For US Cellular, I've seen it as *228 and *22894. You may have to call your carrier and ask what their phone programming code is.
Aaah ok I got you now. Yes I've tried that on nearly every ROM. Matter of fact I just noticed I posted a little off topic almost, but I'm here for the relevance of com.android.phone crashing EVERY SINGLE TIME I try to open Cellular Networks. The only ROM I will say it doesn't force close on is the Slim Nougat ROM, but I don't run that because instead of Cellular Networks settings making com.android.phone crash its when you place a call and then it force closes the UI part of the call but still carries the call through. I forgot to mention that by the way, whatever it is in Slim that is the making the different reason for force closing com.android.phone could probably be a pretty easy red flag for someone better equipped for this Lind of troubleshooting than myself!
Thank you for the suggestion though on the *22(8 in my case)

After I posted that, I went back to try and see if Lineage was able to pick up my phone's MEID (even though I use a GSM SIM, the MEID is still tied to the phone hardware). For some reason, Lineage is not reading it, and I think all of your problems are being attributed to that fact.
The way CDMA phones work (and god, do I hate this), is your 2G/3G network is tied to the phone MEID, while the LTE SIM is data only. The OS needs to read both the 14-digit MEID (sometimes shows as a 15 digit IMEI where last digit is 0) as well as the 20 digit ICCID (SIM Number). A phone may also use the SIM number itself as an IMEI (BYOP SIMs do this) by dropping the first five digits of the 20 digit SIM number.
If you phone is showing only one 15 digit number in the system settings, then it's either the MEID OR the SIM, not both. So either you have calling and no LTE, or LTE and no calling. You can't program APN settings because the phone has no idea what ID number to tie APN settings to. This is actually a rather serious conundrum.
Ok ok, makes sense. I checked my Status info, every ROM has dual SIM capability by the way so I don't know if that would effect anything for xt-1607, but I looked at SIM slot 1 info and it reads my MEID correctly with 14 digits. I couldn't find anything about ICCID. My head pounding question here though, why in the hell (pardon the language) is everything flawless on stock, but on every ROM this problem occurs? Here's my next killer, everything works like it should for me, LTE, 3G, Calls, SMS/MMS, just can't change any of the settings due to a force close, AND I put my friends Straight Talk SIM in and it fired right up with no force close when going to change Network settings...?!

I think you just answered your own question. As stated in PCMag back in 2015, "Nobody makes a Dual-Sim phone compatible with Sprint or Verizon." It legitimately believes your MEID is a GSM-based IMEI, and is attempting to cross the streams, so to speak. And the only way your friend's StraightTalk SIM would work is if it was piggybacking off ATT or TMo's networks (the MEID would have been paired to the other phone causing a mismatch).
If you look at the stock ROM for this phone, you will see a BUNCH of system apps for programming Sprint and Verizon network information. They never made it into the custom ROMs we're using. FWIW, here's my thoughts on the matter. Someone needs to go back and make a single-SIM variant of these ROMs, as well as a flashable ZIP containing the necessary APKs for Android to detect the necessary information correctly. And if that doesn't happen, then everyone who bought an XT-1607 has to ditch their carrier and move to a GSM carrier.
That makes complete and total sense! Because I wasn't thinking this while time of it but I was in Oklahoma at the time where the main towers are AT&T, matter of fact Sprint and U.S. Cellular lose almost all signal right when you hit the county line where I was at. Verizon only gets signal because it's Verizon, lol. Reason I say that is because I was wondering why this whole time I has full signal with LTE coverage and completely list everything when I went hone, because where I live is complete opposite, there is hardly any GSM coverage, we don't even have an AT&T store, just Verizon, Sprint, USC.
So, with that being figured out, my laptop just recently kicked the bucket on me so I'm out for the most part, I do have a trick to swap files in and out of a compressed archive without extracting it in any way! But, it takes a while, not too much longer I guess but nowvi just remembered everything is pretty much .dat files so nevermind that.
Not that this thread isn't the most popular, but where would be the best place to take this request too to get the most attention from it? I mean if I had to go back to stock, so be it, but I'm a little spoiled to the custom life. Lol.

IIRC, there is a Verizon thread with 80ish replies, but I think a developer like Squid might need to be made aware of this, so I might copy this into the Lineage thread.
A bit of good news. While reflashing all the time that were force closing when opening cellular networks, I looked in /data/data/com.android.phone/ and was looking, now remember to go back to that directory after I say all this, I found that directory was empty, on all of the Roms. Was curious so I flashed back to stock. Went to the same directory, BOOM! com.android.phone was not empty, in that folder I found 2 folders that were now populated with in:
1: (/files/ )I now had a file named carrierconfig-com.android.carrierconfig- (and after the dash was my ICCID number) so for this directory I need /data/data/com.android.phone/files/carrierconfig-com.android.carrierconfig**ICCID** (replace **ICCID** my ICCID number)
2: then there was this /data/data/com.android.phone/shared_prefs/_has_set_default_values.xml
and
phone/shared_prefs/com.android.phone_preferences.xml
These files are missing on all the Roms, I know this doesn't since everything, but I know for almost a fact it's a good chunk of something that needs to be available. Can I copy these files and move them into place, and set permissions how they were? I ran out of time tonight, and am busy all week so this is mainly for reference I guess. More research told me these files can be edited to change what is available to configure in cellular network settings like option to change from 2G, 3G, LTE, APN, and so on. Sorry for the mess, that's all I have for right now.

That is definitely a major find! My only concern is even if you do that, there might be further missing components that would cause Dialer to crash on startup or some other wacky side effect. However, if you can make it work, then it's possible the proper APN settings will load by default and you'll no longer need to change them.
If you can, go into the System Apps on the stock ROM and look for any APKs branded by/with Sprint, VZW or USCellular, or anything CDMA related. They might be necessary for reading the SIM's ICCID.
That's what I was thinking too, and sadly for me I don't really know EVERYTHING to look for so it'll be mostly out of trial and error for me to figure it out. I wish they didn't compress Roms into .dat so I could use a root explorer to swap between tabs rather than copy, flash the rom, paste files and then if that didn't work start all over on restoring stock, so on and so forth. I miss my laptop. =(
Updates?
Has anyone looked into this further? I'm experiencing the same problem with the latest LineageOS nightly. US Cellular Prepaid with an XT1607.
I noticed that in my case i had to skip the Insert Sim thing on 1st boot. It never did whatever it wanted to there. (Maybe because I have no signal or weak roaming where I live?)
I'm seriously considering trying it from an area that I have good service in..
