[Q] problem with 3G/4G when leaving WiFi - Samsung Galaxy Nexus

I just flashed CM10.2.0 from 10.1.3. I performed a wipe of data and cache so I'd consider is a clean flash. Since doing this, the phone will usually not switch to 3G/4G over the air when I leave WiFi. If I reboot the phone, it immediately acquires 3G/4G. This was never an issue with the previous ROM.
I see a lot of posts about these kinds of issues with the current nightlies but can anyone offer suggestions for a fix for the CM10.2.0?
I'm hoping that I just have the wrong radios flashed for 10.2.0/4.3.1 - I'm on FK01/FK02 and on Verizon so CDMA...

wow, would have expected to at least get some replies on this given this is a topic that is going hot and heavy regarding CM's latest nightlies.
Bottom line, I did a clean flash and the phone now has a terrible time doing any sort of handoff to cellular data from WiFi. Sometimes I'll see a 3G or 4G indicator and still not get any data, sometimes I don't get any sort of 3g/4G indicator and just see signal bars.
I've even had the phone refuse to make a call - it performs everything like it is making the call but nothing, just silence. I've never had any of these issues before so I'm going to have to assume something in CM10.2 is the culprit.
Going back to 10.1.3 I guess even though I do like some of the features of 10.2.

[Q] Phone keeps losing data connection

My wife is having issues with her data connection on her phone-
The phone aspect of the Captivate Glide works fine, but there are times where she is trying to us data (to check emails..etc..) and phone states she does not have a data connection. Also, her 4g icon disappears from the screen. Only solution (which she completely hates) is restarting the phone. Have had several android phones, but this is a first for me-
Currently running OsiMood.0122.RUXKJ5 Android 2.3.5
different ROM, same issue
so i updated my wife's phone to thegreatergood's literom (version .6), and I'm still having issues with the phone sporadically losing it's data connection. my wife is still able to make phone calls, however, all texting and data remains off. I have to restart the phone in order to restore data/text...any ideas?

I have seen this as well once or twice in the past as well. I am also on the greater good's literom 6 and liteKernel v4. Rebooting does fix it. Not sure what is causing it as well. I think it happened when I had low reception then all of sudden no reception all together. Wonder if you have no reception for too long can trigger this? Rebooted and wen back to having low reception but at least some. My work has a lot of interference so I rarely get good reception at my desk, often I see the E sign for edge network and when I see that I know it is going to be Dog slow.

[Q] Signal Issue?

So I've had my VZW Galaxy Nexus since launch, and have absolutely loved it. It is by far the best phone I've ever had, and I've had zero problems with it... except for recently.
For the past few months I've had a problem where my signal bars get greyed out and I can't access anything, even when it shows I have full signal. This will happen on 3g, 4g, and wifi, and sometimes toggling airplane mode on and off will fix it, but most of the time I have to just wait for the connection to come back on it's own.
I've read about signal issues plaguing the Nexus, but I always thought it was just where it showed no signal at all. Am I experiencing the issue, or is it something else entirely? And is there anything I can do to try and fix it other than getting a refurbished phone? I have tried every radio combination out there, and have settled on the latest radios (l515.09 V.FF02 / l515.FG02) and the issue has persisted throughout.
TLR - Phone will often grey out bars and I can't connect to anything. Happens in 3g, 4g, and wifi. Is this the signal issue people have been talking about or something different?

Try getting a new Sim card. I've read on other Gnexus forums. That's good fix for the gray bar issues. other solution take out the Sim card and let it sit for a minute or 2 then pop it back in. Lastly a factory reset.

a signal drop is when your device's antenna looses conection to the nearest cell (tower, mobile transmission equipment) totally.
a data drop is what you're experiencing.
this is on stock rom, correct?

It has happened on stock rom. Right now I'm on AOKP JB Build 4 with the 20120726 gapps from goo.im/gapps.

ATT GS3 losing Data Network randomly

This is the Task650 and Ktoonsez AOKP. VERSION: d2att(4.1.2 JZ054K) from December 2nd release.
My data network goes in and out at random. It actually started happening about 4 days ago on an older build by Task650 & Ktoonsez but I saw the new one so wiped dalvik and Partition cache and rom'ed. Even after flashing the new ROM, data is acting the same way. It is completely random, happens when the phone is in use or when it is locked. I can tell when data connects for short spurts because I hear the notices for new emails. All in all today, I've maybe had 5 minutes of HSPA/3G data and the rest all I have is cellular network for calls. reception strong, and I am in areas where I always have good connection and speed.
Any ideas? Kind of frustrating if I am out to lunch and want to catch up on things (stuff is blocked at work). Also I am paying for data I can't use :/
fully wipe and reflash.. try a different modem

I am admittedly new to flashing, I just assumed everything was in the package. I flash the ROM and Gapps, is there a source for different modems?
This is definite disconnect of data DHTP. Can't get anywhere, and there is no symbol where there usually is on the reception bar. When it comes back for brief moments, it has either HSPA, 3g, etc.... on the bar.
are you able to send and receive calls? text?
I flashed that rom three days ago, and i had to replace it via warranty. it showed it had signal, but couldnt make any calls or text at all. then i Odin back to stock never worked again.
Don't think it has to do with any rom. Noticed that my wife's sgs3 has had a problem sending and receiving texts and the network drops a lot as well. She is completely stock with the jelly Bean update. My network has been a little suspect over the last few days also. Might just be the service.

Hey Guys, I may have found the culprit...sort of.
The wife has an iP5 and she said to me while we are driving to a holiday party 'I finally have official 4G LTE on my phone'. To which I of course ask what she means. Apparently the same day I started not being able to connect to data networks, is actually the day that ATT fired up their 4G LTE tower(s) in the Lehigh Valley area. When I do get data on occasion, it's when I bump down to 3G and HSPA. Unfortunately, the ROM has a bug where I cannot force it to look for just 3G, I go to save the setting and it immediately jumps back to LTE.
I may just have to flash to a version that definitely supports 4G LTE data. This issue occurred before I flashed to newest ROM, so it has something to do with the core build or modem that both versions use.
Ngriffin, if you find any successful modems please let me know. I like the ROM but I can't go without a data connection much longer.
So, for those who care, I flashed Gapps and also Flashed a new modem (http://forum.xda-developers.com/showthread.php?t=1831898) version UCLG1 and it's a no go. A few in my area said it worked great for them so now I am a bit discouraged. Northeast Pennsilvania Area.
Modem coverage map (submitted by XDA users) https://maps.google.com/maps/ms?msi...ll=40.898982,-75.992002&spn=0.052809,0.111494
Versions tried:
LG1 -------------Did not work
LEM
LH9
LK3 -------------Works but only 3G data.
LH1
CLI5
More info, tested using the Wife's Ip5 and realized we don;t have LTE at our house, so I'll have to wait until we get withing range of the LTE tower(s) to see if it has an issue. However, I now have data reliably.

That's normal. LTE is data only and isn't used for phone calls.
I've been running Task's AOKP on my SGS II and III for a while with no data issues. Check your APN settings. If you're in an LTE area, you should be able to sit on the ATT LTE APN and have no problems, even away from LTE coverage.

To update further, LK3 modem worked for a short while, but once I left the area of my immediate cell tower and it had to connect to another tower, it couldn't. I flashed ALL modems in my list a post above and NONE work. I'm kind of pissed right now.
Any ideas? I'll probably to a full backup and then flash a completely different ROM and cross my fingers. Is there an official JB stock ROM sans the bloatware that is stable and can connect to LTE (or any data network reliably for that matter)?
It was my APN *facepalm* Thanks for the suggestion. It was sitting on wap.cingular instead of the LTE and it was causing the issue. I'm on modem CLH1 and it is working, I have the 4G (3G) symbol now and data is connecting. Well, I learned something thanks! :victory:

I started having issues with mine about the same time. I haven't been able to figure it out yet. I had just gone to JB and flashed a new ROM. Then started noticing not just data being very spotty but also my calls (both incoming and outgoing) were very spotty too. Both seemed to only work about 50% of the time. I have since completely wiped and factory reset twice. I even Odin'ed back to a stock Rout66 jelly bean system but I still have issues
I have updated my APN to ATT PTA but that hasn't helped. What APN settings did you go with? Is ther some specific for LTE coverage? On the stock system now I can actually see the LTE icon when it actually chooses to connect.
Also, where did you find other modems. I was told in another forum not to flash any that weren't specific to Jelly Bean and all I have found is the stock I747UCDLK3 which is already on my phone. I did try flashing that seperately just to see if that would help but did not.
I need to get my phone working pronto as it is my main phone for both business and personal phone calls. Any help would be greatly appreciated. Thanks in advance.

I thought they changed the APN to "ATT PHONE"? Trying to find those details now.

When you're on stock, only thing you can do is check with your carrier and they'll either tell you that it's something on their end being worked on or that your SIM card is faulty.
This happens to me on tasks AOKP ROM at least once per day, but it usually only happens when I turn on LTE. Basically what happens is the phone has cellular service but no data, after a few minutes it comes back. What I have noticed is that its to do with LTE so maybe there's a problem with that?

Task's AOKP doesn't set the default APN to LTE for Rogers so you might wanna make sure it's your default APN.

[Q] Bell Canada i747m losing connection

hey gang i'm running the latest aokp task650 build on my S3 I747m. Everything works awesome, except i occasionally lose my data connection. I'll notice my connection status bars are gray, and typically a reboot will fix it. I'm sure going into airplane mode and back out from that would re-establish the connection too.
my APN is set correctly, i compared it to a friends nexus which is not rooted.
Right now i'm set as pda.bell.ca
I've flashed the latest bell modem file (that i'm aware of).
Anyone have any suggestions? i'm pretty new to all of this.. not sure what to do to troubleshoot.

I've been having problems lately when I have poor 4G (LTE) signal. My phone would rather hang around on the LTE network with little to no signal before it switches over to 3G. It's been doing this for a while on the Rogers network for me. I can see when I check the battery stats just how much time is spent without signal which is a lot. At work I get full bars 3G when at my desk but very poor 4G. The only thing causing me to loose signal is the poor transition back and forth between the two networks. Changing modems has absolutely no affect on this matter and I've put the APN's and network modes through the ringer with no change either. I've tried it all and nothing improved it. When I walk outside I immediately hit full bars 4G. Just when I'm inside my work and at home, I get poor lingering 4G. I wish the thresholds for when it switches over were better. I usually just turn off LTE all together which sucks but oh well.
I don't think we are the only people with this either. I've read grumblings about others noticing the same thing.
If curious, I'm running the latest CM10.1 nightly with Ktoonsez kernel on the Rogers network in Ottawa.
Interesting, that could very well cooincide with what i'm seeing. I tend to bounce from 4G to H+ or 3G, i wonder if it's trying to hang onto 4G.
Is there a way to force it to stay on 3G? that might be a good test
I was getting the same issue.
I did a factory reset and reinstalled my ROM plus GAPPs and the issue resolved itself.
I am using the latest modern right now and not my bell one. I think it's from a south American carrier, but bit 100% sure of the top of my head. But it is in the current modern thread

I'm seeing the same problem with the latest snapshot (cm-11-20140104-SNAPSHOT-M2-toroplus.zip). I plan to switch to CM 10.1 for now, as well, since 10.2 still has known "Issues between 4G and 3G switching".

I updated from CM11 Snapshot M2 to the recently posted Snapshot M3. The 3G/4G handoff problems that I was having in M2 appear to have been fixed in M3. However, the (stock) portable wifi hotspot function isn't working properly for me now with M3.
After some additional testing I've found out that my signal cuts out and has problems reconnecting after activating the portable wifi hotspot (similar to the previous 3G/4G handoff problems). And the my other devices can connect to the portable hotspot but they do not get an internet connection. It appears that turning off the portable wifi hotspot and then toggling data may reset the data connection.
Is anyone else experiencing the same behavior?

I've been having all sorts of data issues lately, even worse I think with M3. But, I haven't cleaned flashed in a while. I hadn't thought to try toggling hotspot--I'll have to try that next time I can't get any data (3g or 4g). Over the weekend I had to hotspot my phone a bunch and since lte doesn't yet reach my house I had to hotspot 3g and that was working just fine. I'd be interested though, if you're consistently having good 4g data or if it was just a momentary fluke for a day. It seems like some days I've had no issues with 4g and other days it's been a bear where I struggle to even get 3g.

yotvb531, your suspicions were right... After 1 day of flawless data handling on CM 11 Snapshot M3, I experienced a hiccup during a 3G/4G handoff. Soon after, the data handoff problems became routine like they were with Snapshot M2 (perhaps worse). Although toggling the data connection would get the network to reconnect, the data connection problems occurred often enough to make me revert back to CM 10.1.3 a day or two later.
I'm now anxiously awaiting the next CM 11 Snapshot, hoping the data connection problems will be fixed.

After not being able to pick up 4G from the snapshot on, and hearing from others that they had 0 issues on a clean flash, I finally spent the 5 hours to clean flash my phone (I also formatted the sdcard while I was at it because I hadn't done that either in a very long time).
Happy to report that ever since then (12 days and counting) things have been very smooth. I've had issues only twice, but based on the behavior I'm pretty sure they are attributed to cell tower maintenance and not my phone freaking out...mainly because it didn't matter what I tried and then hours later after I had given up messing with settings everything started working again and was then fine for a week afterwards...and also after that outage the data speeds went from 1 Mbps to 8 Mbps.
Not saying a clean flash will fix everyone's problems, but it definitely did wonders for me...fingers crossed that when I finally decide to move on from the 2/13 nightly everything will continue smoothly.
There I went jinxing myself! I had to toggle airplane today after leaving work to get 4g to pick up. Was stuck on 3g EVDO. Toggling airplane mode got it to switch over to eHRPD which then allowed it to pick up the 4g. So maybe the hand-offs aren't perfect, but act fine most of the time--in my situations.
That same behavior happened once before on this same nightly (2/13) and I chalked it up as tower maintenance. That was in addition to the other time I mentioned where speeds jumped from 1->8 Mbps and I didn't have to do anything for the lte to return. I think that one was actual tower maintenance; just the other one wasn't...and it happened again today...twice in 14 days isn't too bad but it's definitely not perfect.

If I could get CM 11 to behave like that I'd switch right back to it. My problem wasn't that it would get stuck on 3G, it's that it would get stuck and not have any data connection until I either toggled data (e.g. airplane mode) or restarted. This would happen multiple times per day.
While I always clean flash, I never format my SD card. I assume this step has to be done separately from flashing, correct? Is it a best practice, or can just the Android folder (any others?) be deleted?

I did my internal storage wipe at the same time under advanced wipe in twrp (cache, dalvik, data, internal storage). I don't think it has to be done very often...I hadn't ever done it since the toroplus phone first came out so I had a lot of garbage and hierarchical messes all over the place (the 0 folder in 4.2 that was created...).
I doubt wiping the internal storage has any effect on the functioning of the data hand-offs; but I just don't know either.
