Data Cuts off - Galaxy S5 Mini Q&A, Help & Troubleshooting

G900p 5.1.1 CM12.1. I'm on boost mobile. Data and MMS works fine but sometimes data will cut off and the only way to fix it is to go to APN settings and click the APN to edit it then back out and LTE will come back on. Any idea how to fix this? Pretty annoying.

Maybe wrong subforum? This one of for S5 mini ( G800x models).

GT-N7000 Gingerbread -> 4.0.4 (UK) = No mobile data [FIXED]

Hi,
I have just updated my Note from stock gingerbread to the official UK ICS 4.04 from here: http://forum.xda-developers.com/showthread.php?t=1424997 using Odin.
The phone is now running XXLRK (kernel and baseband) - it's not rooted at this time.
Everything is working fine except that I have no mobile data connection. Wifi and voice calling is fine though.
The Network Signal App shows that I have an HSDPA (7.2Mbit/s) net type but the data state is 'Disconnected'. I have confirmed that 'Use packet data' is on in the network settings and I have re-entered the (Vodafone Contract) APN settings several times.
I have put the SIM in a spare phone and data works as expected.
Any ideas?
Thanks

have you tried checking data usage under 'Settings'? , usually there's a capped set if your way over the pre-determine data cap on the phone. Try to raise the bar all the way up and see if you can gain data connection again.

I'm not sure if it helps at all(in relevance to the OP's issues), bear in mind apn settings are different in every carriers. Manually configuring doesnt' change anything at all... even worse, your just aggravating more his problem.

Thanks to both of you - the APN settings are confirmed as correct.
The data usage sits solidly at 0. I have disabled the cap, but even with it turned on and set at 5GB (my cap is 1GB but since we're only 7 days into the month there's no way I have exceeded it), it makes no difference.
I have confirmed with Vodafone that everything should work.
I have also tried a couple of previous radio images without success. At the moment I have just pulled the battery and I am waiting an hour or so before firing up the phone again.
If I can't fix this soon I might just revert back to stock Gingerbread, but I get the feeling the fix should be really simple.
FIXED!!
I added a new APN to the list and just duplicated the Vodafone Contract settings that I know work. This new APN setup was identical to the pre-defined one (which I had been editing) - but it works!!!.
Stick that one in the memory bank for possible future use!

[Q] Switched to T-Mobile, No MMS over Wifi

Hello,
Normally I can find everything I've ever needed by searching here, but I was not able to find a solution to this one.
I just switched to T-Mobile from AT&T, and brought over my SM-G900A.
When I put the SIM in at first, I got voice and SMS, but no data. I looked up APN settings, and created a fast.t-mobile.com APN using the recommended settings, except for APN protocol. Data now works, but still no MMS unless I disconnect from WiFI
MMSC is set to http : //mms.msg.eng.t-mobile.com/mms/wapenc (no spaces)
APN Protocol is set to IPv4 (This is greyed out and cannot be changed to IPv6)
However, MMS only works when connected to data only, not WiFi. I cannot seem to find a way to make this work when connected to WiFi, which I would like to be able to do. Any ideas?
My thought is this might be related to WiFi calling being a native feature on T-Mo devices but not on AT&T. Thoughts?
Thanks guys!

My thinking is , is thats an internal thing with att software in the s5. Just because u switched to tmobile wont chang the software on the phone to tmobile even ur software updates to the phone will come from att not tmobile. I always have to have data on to send mms. I could be wrong but i think thats whats going on

You can achieve WiFi calling and Texting which will send MMS over WiFi by installing the alliance ROM. You first have to be on KitKat 4.4.4. After thay flash the ND3 kernal and install root via towel root, next install safstrap and flash alliance ROM and bam you should have WiFi calling and texting enabled. I am currently on the at&t s5 using T-Mobile.
I may have the links on my laptop if you need them. Just let me know.

Nexus 6 Lra carrier help

Hello, I recently purchased a gpe nexus 6 for my cell carrier Thumb cellular. Small company that uses verizon towers in rural America (LRA) one of the bigger LRA carriers is bluegrass cellular if it would help any. Basically these LRA carriers partner with verizon to give coverage in rural areas otherwise skipped over. The phones themselves are almost exact clones over their verizon counterparts for what that may matter.
My issue is I have a bug where I can not send out sms messages on lte but when preferred network is set to CDMA only Prl it works. Set back to lte CDMA and they fail to send again. Everything else including receiving sms works. Any idea on what I can do because I don't want to send this device back. Seen its common on CDMA carriers but no real fix has been found besides to stay off lte. Any help would be great, Thank you
Sounds to me like it might be something with the APN's. Maybe you could look at another (android) phone that works properly, and see the apn's, and then manually enter them in the nexus?

I have a galaxy s5 on the same network and saved the apns and restored on the nexus using apn backup restore, I get lte and can send mms. The issue is sending regular sms while on lte. If I force 3g or even 1x I have no issues sending a text. Seen its common issue with this phone on a CDMA network but no idea what to do to fix, updated to stock 5.1 as soon as I received the phone, tried chroma as well as bliss pop and all have the same issues. Really don't want to return the phone but doesn't seem like there is a fix

Why did you do apn backup/restore rather than letting the n6 pull apn info from your sim? That may be why you're experiencing issues?
Although, standard sms doesn't have any specific apn settings afaik, and should just work as long as standard voice works...
Btw, what build are you running?

Did that before I restored apns actually. Had an issue so that's when I used my thumb cellular apns which are different then the verizon ones it gives me thinking it would help me for some odd reason even though apns have nothing to do with sms.
If I go to dialer and dial *#*#4636#*#* I have LTE/GSM/CDMA AUTO (PRL) everything works except sending an sms. Only thing that won't work. If I change it to CDMA only I will get either 1x or 3g but my phone works how it should. Should have absolutely nothing to do with apn settings. Seen this issue is common on verizon but more so on sprint but not everyone is plagued with this problem, but exchanges and new sim cards don't fix the issue for those whom experience it.
I'll post a log cat, I don't know what to look for so if someone could it would be great. I'm testing with 8sms
https://www.dropbox.com/s/xwj5q7wut05ybhl/Log_2015-05-30_22-12-22.txt?dl=0
I'm looking for answers too I have a similar carrier (another partnered with Verizon in the lra agreement) and interested in buying a n6 provided this issue can be resolved. Being a carrier that functions the same way I'm 99% sure I'd also have this same problem.
What doesn't make sense is that when network mode is set to LTE/CDMA AUTO prl, you cannot send sms but you can receive them, send/receive mms, make and receive phone calls etc. But if you do cdma only and limit it to 3g, it all works.
Does anyone have any suggestions in things to try?

I tried that before and had no luck. Going to try different modems tomorrow and a couple BP edits. Running out of ideas to try sadly. Only idea I have is how the phone is communicating with the network, same issue I saw on the nexus back in November with the sprint network. Seems like a radio update fixed the problem.

[HOW TO] Fix LTE Issue with CM 12.1 based ROMs and Sprint as your carrier

This may fix jfltespr on the Sprint network always worked fine with LTE on most ROMs, but not with very many ROMs lately.
It seems that the APN had one slight difference between ROMs that worked with LTE for me (older CM, stock TW, GPE), and ROMs that had no LTE or eventually dropped LTE (CM12.1 based). The bearer was not set to LTE in the APN profile for the ROMs that do not work for me. Changing that quickly fixed the problem (figuring it out took me much longer). I looked around a bunch when I had this issue, and found people with the same issue, but no solutions. So, that's why I post this here now. Here's the How To if needed:
Go to Settings, Mobile Networks, Access Point Names, and Sprint LTE internet.
Scroll down to Bearer and see what it is set to. Mine was Unspecified, and that's what was causing the issue. Set Bearer to LTE
Go back to APNs, and also set Bearer to LTE on Sprint EHRPD internet. I know that's not the normally selected APN, but if you only change Sprint LTE Internet, it seems to automatically change to this EHRPD one, and it still doesn't work.
That's it for now. Enjoy your LTE again on 5.1.1. It seems to be much smoother.
I'm on an LG G3 but this APN/LTE issue seems to be affecting a lot of people on Android 5.1.x. I've been searching for solutions for days. Unfortunately, I have to report that your method did not work for me. With the Bearers changed to LTE I'm not getting any connection at all, but with them Unspecified I'll get a connection for a small time (<1min) after switching preferred network from 3G back to LTE before it drops again and gives me the exclamation point. If I leave it on 3G I have no problems retaining a 3G data connection. Nexus owners appear to be having this issue en masse with their 5.1.0 & 5.1.1 updates from google so it doesn't appear to be a CM issue, though CM had some APN related commits on July 1 that also seemed to cause problems for people and were undone by devs of some CM-based roms.
Yea that's a bummer. Thanks for sharing though. Maybe having it happen to so many people means that it will get fixed sooner than later, but I can only hope. I can only speak for the Sprint version of the S4 running on the Sprint network. It seems that people with this exact phone are okay on other networks.
This fix wasn't 100% for me either. Every once in-a-while, I think mostly in particular locations, it'll get stuck on the exclamation mark, and I'll just have to throw it into airplane mode for a moment.
If you haven't tried yet, make sure to put the bearers to LTE for all APNs that have the same DNS name as the normal one that you use, and the others at their defaults. It's probably not the case, but your results sound similar to mine when I only set one of the APN bearers to LTE. I thought that might be worth a mention, but I'm sure there are deeper problems. Sounds like you probably already did that anyway...
I've been having problems with this too and I tried your method but it didn't help me. It's really frustrating when there's so many great roms that are useless but thanks for trying though. Hopefully it gets resolved soon.
AOSP automatically selects the correct APN as long as the bearer is unspecified. You can hard code the bearer, but then that APN is only valid for that bearer. In other words, setting the eHRPD bearer to LTE will make that APN only valid for situations where the radio is connected to LTE. However, the connection will fail because the APN settings are wrong and the system will automatically move to the next APN with the bearer set to LTE. This time the connection will succeed because the next APN is the LTE APN. If you set the eHRPD bearer to LTE then you will never get a 3g connection.
What exactly are the symptoms you guys are seeing with LTE? My wife and I are both running CM with no connection problems whatsoever.

For me, I just randomly lose data connection, both 3G and LTE. It will then reconnect a few minutes later. I tried removing the other APN like the freedompop & ting leaving only sprint APNs thinking that might help but it I still lose data.

Do you get an explanation point?
Take a modem log right after you lose data and send it to me in a PM.

MMS ???
Hi. I am running CM12.1 and have tried other Lollipop roms. I am using Ting as my provider. I have two issues.
1. I don't get voicemail notifications. I can live with that.
2. Picture messages don't show. Texts come and go with no problem, just not picture (mms) texts.
Would these fixes help my issue? I have had no issues with 3g, which is most of my coverage area. I am usually on wifi anyway.
Thank you!

Cm12.1 ignores the voicemail notification from the carrier. The MMS issue is an incorrect/missing APN. If you can figure out what it should be we can get a patch submitted.

Here is a jfltespr build that fixes Ting data/MMS. I strongly recommend a clean install. If that's not possible, be sure to reset APNs to defaults after you flash and then reboot. It will take a minute or two to get data after the reboot. Please let me know how it goes. If this does fix it, I will submit the patch. If not, I still have some ideas.
Be sure to make a nandroid backup as I couldn't get my wife's S4 to test it with and this was the first time I have built for the S4 on this machine.

I loaded it on and everything works except for mms. My 3g is good, wifi, texts, internet, calls ... just no pictures in texts. Something I noticed was different from the other CM12 versions is that now I can see that the text was sent, I just can't download it. I tried these settings from this page - I used the EHRPD settings. They were able to make mms work using the Octo rom.

What fixed your problem? Setting the 3g bearer to LTE? That means the freedompop LTE APN is wrong and should be patched in the code. If we could get more input on this we could fix it for good.
I don't even have anything listed in my APN (I used to). How do I fix that?

Tap airplane mode, then tap again to turn airplane mode off. Then go into your APN menu. Your APN's should appear.
I'm running the latest CM 12.1 nightly. The stock APN's work for me, but I rarely get a LTE connection with them.
I've flashed the APN fix that's floating around, and it worked in older builds of CM 12, but recently the fix just disconnects and leaves me with no signal.
If I do what OP suggests, I'll get an LTE connection, but that leaves me with no 3G where LTE isn't strong.
I guess the problem with CM is that it cannot successfully switch between LTE and 3G correctly.
If you're not all that concerned about getting an LTE connection, I'd recommend just sticking with the stock APN's. Once you start flashing fixes, you're gonna have a problem.

Android 5.1.1. Update Disables Mobile Data (D5803)

Hello,
I recently updated my Z3 compact (D5803) to android 5.1.1. on the T-Mobile network here in NYC. Ever since then, I frequently lose the ability to do anything data-based with the phone. No web browing, no chatting on whatsapp. I can still make phone calls and send/receive SMS, however. The data functionality returns when on WiFi, but goes away once I switch back to LTE. In order for me to get data on LTE, I have to manually download the internet settings for my provider to my phone (this is located under the Settings menu in android). Even then, it only lasts for several minutes before the data connection is lost. T-Mobile was unable to fix the problem, and changing the SIM card didn't resolve the issue.
Anyone else experience this?
Yes, many others have the same problem, see various posts in this thread: http://forum.xda-developers.com/z3-compact/general/discussion-5-1-1-stock-released-post-t3162309
Currently, the best workaround seems to be to disable and re-enable mobile data, or to go to airplane mode and back again. That solves the issue until you drop LTE connection the next time, then you will have to re-iterate.

In order for me to get data on LTE, I have to manually download the internet settings for my provider to my phone (this is located under the Settings menu in android). Even then, it only lasts for several minutes before the data connection is lost. T-Mobile was unable to fix the problem, and changing the SIM card didn't resolve the issue.
Anyone else experience this?

Yes I am having the exact same problem since updating to 5.1.1. As the other reply says turning airplane mode off then on is the quickest way to get connectivity back (swipe down twice from the top for quick access). This is terribly frustrating though, it only lasts for a few minutes. I can't believe they pushed the update with this issue!

Yes, many others have the same problem, see various posts in this thread: http://forum.xda-developers.com/z3-compact/general/discussion-5-1-1-stock-released-post-t3162309
Currently, the best workaround seems to be to disable and re-enable mobile data, or to go to airplane mode and back again. That solves the issue until you drop LTE connection the next time, then you will have to re-iterate.

My phone had this issue after the over the air update. I reset the phone to factory, wiped all data. Two days on, now, and no more problems with this.
Same problem. I tried factory reset out of desperation, but it didn't work.
Love this phone, but very discouraged by this bug.
(I'm on t-mobile in Seattle, fwiw)

As posted in the other thread, there is now a fix/workaround:
From reddit user FishStik5: Going into the APN settings and changing the APN protocol to iPv4 only (it was iPv6 before) seems to fix the problem.
How to find the setting: Settings-> Wirelessa and Network / more -> Mobile networks -> APN -> T-mobile data -> APN protocol -> Set to IPv4.

Looks like this worked for me (T-mobile, San Francisco area). Thanks for posting this
i'm having the same problem and didn't work for my the ipv4. still loosing data, i have to reboot the phone
I have also problem with that (Orange, Poland). I sent my phone to official Sony service, they reload the software, but I still have that problem. Lte is working for a while and when my phone switches to wcdma (because it is not in a range of lte) it is not working either. However, when I change the preferred network from lte to wcdma it is working without any issues.
Same problem here although I'm on ipv4 [emoji34]
Sent from my Z3 Compact
I thınk you shouldnt buy operator phones. Buy ınternatıonal models next tıme
Mine isn't an operator model, I'm using Straight Talk and also have the issue. It made my phone useless....I almost never have data
This worked for me
This worked on my Doogee Valencia2 Y100Pro
Install and Open app "Hidden Android Settings" (by 0Alex)
Select choose and open "RadioInfo"
Move to Last option "TOGGLE DNS CHECK"
mine read "0.0.0.0 not allowed"
press the "TOGGLE DNS CHECK" so that it displays "0.0.0.0 Allowed"
That's it - my mobile data worked, I hope it works for yo

1. Change "APN Protocol" to IPv4
2. Change "APN Type" to: "default,supl" only
3. Change "APN" to "internet"
4. Save.
Best, Martin.

this is a bug on 5.1.1 sony need to fix it
Any news with this issue?
No problem here with LTE on the CM 12.1 Cyanogenmod flavor of 5.1.1 on T-mobile (that I've noticed at least). But I think CM 12.1 may handle the APN settings differently (mine is set to T-Mobile LTE ipV4) from the stock ROM or it could be something Sony messed up from the AOSP code. I'm NOT suggesting anyone try a CM ROM as a solution as there are lots of downsides to unlocking your phone and flashing any non-stock ROM. But the problem does seem to be specific to the Sony ROM and not 5.1.1 in general.
I also have this problem after the update to 5.1.1 in the Netherlands. The first problem was that the update changed some mobile data settings, so I downloaded the settings from my provider. Unfortunately those settings were also incorrect as I had to manually remove the APN's Proxy and Port (they were set, be needed to be 'not set'/empty). This improved the connection a bit, but it still looses the mobile data at certain places (where the coverage is good). Did a factory reset as the Sony helpdesk suggested. For a few days this seemed to help, but again the same issue came up. The suggested solution mentioned in this thread did not work as those settings are already applied.
I have a profider (Telfort) which uses another provider's network (KPN's). So after the update I also see a annoying R in the signal icon, where in the previous version it always showed H+, H, 3G.
Does anyone know if this is resolved in the new update?
After the last update and a new reconfiguracion on the APN now work correct for me.
