Dropping calls on Tmo - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

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.

Is it Possible to Force the Hero to Roam

Any way to accomplish this?
I need this BAD too! Reception at work is god awfull. Please help! SOS
What does your user name mean? Natural light or natty boh light?
Please someone make an app to turn on/off roaming; I'm willing to pay money for it (and I'm sure a lot of people are willing to do so too).......
LOL if it were this easy.......
Roaming is of no use to me but I always like to look in to issues that people are having. I grep'd what code we have available to us for our phones and the only two options I came across were:
ro.com.android.dataroaming = true
xml: name="sync_while_roaming">false
So all I can tell you is that I can control whether it roams or not (which can also be easily changed in our settings menu) but not to force it to roam. I googled if it was possible in android at all and couldn't find any results.
Do you know what towers are around you or what towers we can roam on? I wonder if it would be possible to hack in a verizon rom dump from eris and force it to roam on their towers. However that won't allow you to come back to Sprint. And Sprint has been known to cancel contracts of people who roam too much.
has anyone tried to update the PRL to a verizon PRL?? I tried it, but i'm not sure how successful it was, as both Sprint and Verizon signals are strong in my area.. Put the PRL on the SD card and use ##PRL# to update it..

The towers around me are Verizon towers. Yeah, I undestand that (Sprint has been known to cancel contracts of people who roam too much) and I don't want to Roam all the time, just here at work. The phone is mostly on roaming while at work but is is continually searching for a Sprint tower and that drains the battery so fast! The only workaround for me is to set the phone to airplane mode until about the last three hours of work but then even when the phone is turned on it constantly tries to switch to a very weak sprint signal and I keep losing connection just about every 2 or 3 minutes, so using the phone in work is practically useless for me right now
@mroneeyedboh: Natural Light. My ode to cheap beer.
One area I frequent has a weak Sprint signal, and a "decent" Verizon signal. It would take "excessive" roaming, for 3 consecutive months for Sprint to flag you for abuse. So you have some breathing room. I remember my G1 had an option to manually select the network available. However, I'm not entirely sure that having a network option isn't just a customary feature of a GSM device, and not Android specifically, since its obviously compatible world wide.
I have the same exact situation at work where I get no signal on sprint but it tries to find it draining the battery and preventing it from using the very good verizon signal. I had to force it to EVDO only just to be able to check my gmail and confirm my XDA forum registration since webmail is blocked at work. This the kind of thing I bought this phone for to always have access to my email. Switching to EVDO Only mode is really cumbersome and annoying, and still gives a bad although slightly better signal. If I forget to switch it back to allow 1x Data, I can't use SMS and when I call sprint it hangs up immediately unless I switch it back on. I would use very minimal time data and voice roaming compared to my outside of building data and voice use as I'm sure is the case for most people with bad sprint coverage inside buildings.

There is a widget in the market to switch 3g on and off. can't remember the name.
Anyone who's more knowledgeable than me, can please tell me if by changing anything in the ## menus, (like ##diag# or ##data#), can we force the phone to roam? (I'm asking because I just got the MSL number out of my device and now can change any of those settings).
TIA.

Sorry, can't help you. I interested in this thread, so I'm bumping it.
This sounds like something the CDMA radio manages. I'm not familiar with the lower level processes and configurations on Android, but this might be part of a closed source process. I don't know if Android is supposed to have such a thing?
You could try setting the Home SID/NID to the SID/NID of the tower where you work, and then set the phone to Sprint Only. This in theory should force the phone to stay on the roaming tower, but I'm not sure if this will override the PRL. Probably not.
Subscribing... I would give anything for this. I got this shiny new hero and can't use it at my house. It was so awesome that I kept it. A friend can sit next to me on verizon and get almost a full signal.
I have tried the GV + Sipsorcery + sipdroid thing to make and receive calls over wifi but it is so unreliable. If I could just switch to use the roaming verizon tower by my house I could justify keeping this thing.
I am new to android development, but not new to development, linux, or java. So I will probably investigate this more.

Apart from force roaming does anyone know of an app that would let you manually select your towers (or a built in way to do it).
I don't want to force roaming actually, I just want to switch to the verizon tower near my house so I can use my phone at home. I don't want to do it anywhere else. Just once instance.
I had a junk nokia a long time ago and it even had an app that let you manually select your tower and gave me all the serial/id info about it. What is the next closest think on android for this?

That is, by definition, force roaming.
Oh, you're right, but what I meant was that I don't want to be anywhere and kick myself off the sprint towers onto any other tower using an app or setting. I just meant in one location I would like to switch to a defined tower. There is a big difference between an app that lets you select your network towers and another that forces your phone off of sprint onto any roaming tower. But thanks for a helpful post.
As far as the CDMA hero goes, is there anything helpful in the radio updates that might lead to controlling the network selection? I am wrapping some projects up this week and I do not care to dig through the source to see if a quick app is possible.
I'm pretty sure you should NOT mess with the radio...

Or, you could call customer care, and tell them that you get no service at home, and require an AIRAVE. They sent me one free, and waived the 4.99 month charge. Just explain to them, you need your phone, you have small kids or whatever, you need service in your home.
AIRAVE is the best thing ever. I went from no service in my house, to 5 bars at all times, who cares if its only 1X, I can still make and receive calls, and have WiFi for my data needs.

How to fix mobile data problems on your OPO!

Well, this is probably the first post I ever posted in one of those forums but I was pretty sure some people might get the same issue so I just thought I'd help out.
I received my One a few days ago, went through hell and back to unlock the bootloader after I already set everything up the way I like it, rooted the phone and updated to XNPH33R and everything was a beauty until I noticed my network acting up. At first it was just the internet connection would drop every now and then then the voice calls started dropping more randomly. I must've flashed my phone like 10 times just to make sure I covered everything.
Then I decided to check the bands used by my service provider, found them on a link on the GSMArena website.
After that it was a matter of setting that on my phone, so I searched online and got this code, *#*#4636#*#*, which should take you to the service menu, there you should be able to make a selection as to which band you want your phone to operate on, as well as the connection type. I set mine to my countrys' band and the connection type to WCDMA/LTE, after that my connection was H+ and it didn't drop for 24 hours now, not even once.
Please let me know if you face any problems doing this. I AM NOT RESPONSIBLE FOR ANY PROBLEMS YOU CAUSE DOING THIS - DO IT AT YOUR OWN RISK.
Oh and the oneplus one is a piece of art, literally.

So it sounds like it may be an issue with your SIM card. I know what you are thinking, what could this possibly have to do with the SIM, on another phone I had, an LG G2, also running CM11 nightlies, I could not get an LTE signal at all on the phone. I took the sim card out of a nexus 5 which had LTE signal with no issues. I put the SIM back into the nexus 5 to see if it was the sim card, and I got an LTE signal in the nexus 5. Tried flashing different radios, flashed back to stock, nothing was working on the LG G2. FInally somebody suggested that the SIM card may have "tied" itself to the nexus 5, I was like that is BS I have never seen this before, sim cards are meant to be moved around to different phones, kind of the whole point of their existence. After a day or two of trying everything I could, I finally gave in and went to see if it was in fact the SIM card that was causing the issue. Lo and behold, new SIM card activated for my account, G2 immediately received an LTE signal. I know this isnt the exact issue you are having, you are having issues with dropped data, but I still suggest before you do anything else, try to get a new SIM card and see if that resolves the issue. On the G2 I went into that same test menu and when I would select LTE it would go right back to WCDMA preferred, would never stay on LTE, once new SIM card in I was able to change between the two. Just my two cents.

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?

[Q] LG G2 Noob here.

hello everyone. i just recently purchased a vzw LG G2 and was wanting to use it with cricket. I know there are many threads and posts about this but after 2 weeks of searching and literally trying everything i figured it was time to throw in the towel and post my situation. So as stated above i bought a LG G2 VS980 about 2 weeks ago and i currently have cricket service unlimted text/talk 20GB data. ok so ill list my issues and what i have tried to correct them
1. From the start i put my sim card in do the whole activiation thing over wifi and when my phone comes on it displays and H which i know is 3G service. I live in chula vista CA. my husbands phone recieves 4G LTE so i know we are in a good area. Now this is where it gets weird, when im connected to wifi the H turns to 3G and even 4G LTE will pop up randomly. My data works fine just slow of course and i cansend texts and calls but no MMS unless i use a 3rd party text app like Chomp or Textra.
2. The infamous sim card icon with a "?" . Are there any solutions to fix this? i have called LG tech support, cricket tech, took it into a cricket store, called VZW almost everything besides taking to a cell phone shop.
OK so i have tried every APN there is out there i have tried the ATT,AIO wireless, cricket,vzw, literally all of them and no diffrence besides recieving a MMS rarely. And yes i restarted my device after every APN input. My phone is currently set on global, when i try to switch to CDMA/LTE after 20-30 seconds it comes up with no network and says i must go back to global. i switch it to GSM and i have the GSM only or UMT only (maybe)? or GSM/UTMS. Not sure which one i put exactly but i put the GSM/UMTS mode and comes up the RAT networks here im confused and really didnt mess with it to much. but it will sometimes say E.
I am also wondering can i system update? i attempt to but it says failed. i kinda know that you cant update a device on any service besides its original one.
Now what are the harms of rooting and flashing? does my phone lose value? like i said im a NOOB here and this phone is literally brand new. I appreciate ANY help i get. If you have any questions PLEASE contact me asap. There is probably some info i forgot the add but i will be waiting for any kind folks to help me out

[Project Fi] Slow Carrier Switching

Hello, fellow Fi users!
It has finally gotten on my nerves enough to create a thread, hoping to find some answers or perhaps work together to come to a solution for Project Fi's dreadfully slow carrier switching logic. I'm not sure about others, but in my town and the surrounding areas, T-Mobile has excellent service. My town is the only town in the county that does not have Sprint LTE, but I do get some 3G in certain areas. The problem is that when I lose connection with T-Mobile for a certain amount of time, the phone will switch over to Sprint to use its 3G network. This is great because this is how the phone and SIM card are supposed to function. However, the 3G service in this area is slow, spotty, and unreliable so typically as soon as I connect (usually while driving or on the move) I lose service again.
The real problem occurs when the phone is extremely reluctant to switch back to T-Mobile. Almost every day I make a 25 minute commute to work that takes me along a route where T-Mobile service drops off for a minute or two. During this gap in coverage, the phone switches to Sprint. I experience one brief moment of Sprint coverage, and then lose that as well (mountainous area). At this point, the phone should search for Sprint service for a few more seconds and then attempt to switch back to T-Mobile. Instead, it stays on Sprint and will continue to do so for the rest of my commute. I have Sprint LTE coverage at my job, but it's the return trip back home that results in my phone sometimes having no service elongated periods of time. Many times I'll look down at my phone while out to dinner after work or something and notice I have no service and haven't for some time. It's simply stuck on Sprint mode instead of switching.
This has forced me to pay for and download FiSwitch on the Play Store. I'm not too upset about this, but I feel like it'd be a bit of fun to maybe try to modify the logic in Fi's networking switching. Now, I don't know if it's possible to actually modify the logic, or where the actual logic resides. But perhaps writing a script or something in Tasker or Trigger could suffice.
The Correct Way to Handle Network Switching?
There are many different areas of coverage and every situation is unique. But I feel like there is some piece of code in there that prevents the phone from constantly switching between Tmo and Sprint. I also understand that this is extremely new, unique and is a work in progress, as Fi hasn't even been out for a year. But if others also experience this issue, perhaps we can find a way to mitigate the problem of the phone getting stuck on one carrier and not switching to another.
Luckily, I have a lot of free time at my job, so I drew up a quick flowchart to show how I'd like to handle carrier switching.
For you savvy coders out there, this would just be a series of conditional statements, which are extremely easy to write, implement and test. Assuming I can't actually modify the logic written somewhere into the phone or the Project Fi app, I'm going to have to make a script or something perhaps in tasker. I can use dialer codes to force the phone to switch to a different carrier, just like FiSwitch does. I feel like it'd be pretty easy to implement, but I'm not sure if it's even possible.
Has anyone else experienced frustration with Fi's carrier switching? I want to know if this is just an isolated case because of topography of my area (Suburban valley, slightly mountainous) or if this is an issue experienced by users elsewhere as well.
I don't appear to have your switching problems. If I loose T-Mobile, it'll switch to Sprint. If I loose Sprint, it'll switch to T-Mobile. If I'm on Sprint's 3G, it'll switch to T-Mobile as soon as possible (available).
I'm using the beta Android N, but I don't remember there being a problem with switching when I was on MM. There could have been, I just don't remember.
Fi stays on whatever carrier has a higher quality signal, and more reliable! More bars doesn't necessarily mean a better quality signal! "QUALITY"is what i want if sprint with 2 bars is stronger and faster than tmo with 4 bars than i want sprint! Whatever's better! I'm sure the fi team spent countless hours and $$$ on developing this software, code, service whatever you wanna call it

That's their claim. But the Fi support forum has many posts from people where this does not happen. Here's a typical example where the phone switches from one to another, then stays on the weak carrier.

I've seen others where the guy and his wife both had 6Ps and his would change to the good network at home, but hers would stay on the weak one.
I noticed myself that even though Tmobile has good coverage at my house, when I forced my phone onto Sprint just to verify it could connect, that it stayed on Sprint even though the signal was barely there. I left it to see if it would switch, but it didn't until sometime overnight. I also once was in a parking lot while trying to see if it would switch automatically and it got down to no connection on Sprint. I rebooted and it connected to 4 bars on Tmobile.
My experience was when I was first on the service. Since then, as far as I know it works ok. My phone is always on Tmobile except in extremely rare instances where it'll switch. Which makes sense where I live in Southern California, because Sprint has always been awful, while Tmobile has added lots more towers recently. The only times it was switched on its own was on the subway (yes there is one here), and at the airport in a certain lounge. I knew from experience that there's no Tmobile signal there, except Tmobile wifi calling would work on the wifi. Last time there, it connected to Sprint on its own, though the signal was weak. But both of those times, it correctly switched back to the much better Tmobile connection on its own.
Glad to hear I'm not the only one with this issue. I'm currently working on a Tasker profile to mitigate this issue. Will take some time to test and perfect, however. I'm still new to Tasker, so there's a lot of trial and error going on here. I wish I could just write something in c++ or JavaScript and have it handle this task instead. I'd be done already lol.

Why can't you? The source code is available, isn't it? A daemon can't be written to load on boot, poll for the strongest signal (at an interval) and switch when a stronger signal is present?

That's normal, if you use the dialer codes or apps to force it to a single carrier, it will stay on that carrier until you run the dialer code to re-enable auto switching.

I forgot to add that to my post. I ran the dialer code to switch, then dialer code to set back to auto. Which is why it switched on its own sometime overnight. When I was in the parking lot, the reason I rebooted was because I wasn't even sure there was a Tmobile signal since I assumed absolutely no Sprint signal would have triggered it.

Howdy -
FWIW - I believe the forced-carrier-switch-by-dialer-code "expires" over time... I am not really sure on that window, but it doesn't seem to stick after a reboot anyway, and I've heard folks say things revert to the "auto" scenario after a couple hours.
Also - FiSwitch happens to be my little tinkering/learning project... I'm not sure I can be of any help but I'd be willing to try I know there is a way to use FiSwitch via Tasker, though that may be a bit redundant if you can fire off the dialer codes without it... just thought I'd toss that out there anyway!
I'm having the same problem. Project Fi worked perfectly on my Nexus 6P but the service has been terrible since I got a Pixel XL. Fi will switch me to Sprint and leave me with no bars for hours unless I manually switch to T-Mobile and then I will get full bars. The network switching actually does work--but it seems to do so very poorly, at least on this particular phone. Fi support has been no help at all.
Btw the dialer code command does expire over time. Even when I manually switch to T-Mobile if I go out for a drive the network will switch to Sprint at some point, regardless of the strength of the Sprint signal.
