Ever since getting my phone, I've had problems with data dropping entirely every so often, but also constantly switching between 3G and H (my Sensation was always rock-solid on H as this is a good coverage area).
Yesterday I was testing the Spotify radio app which streams music. That was the first time I used the data so heavily and the data connection was dropping literally about once a minute. It seems heavy data use causes the connection to drop. Wifi is perfect with no issues at all.
A) Has anyone else run into this and figured out a solution?
B) Is this T-Mobile blocking my data for some reason? Maybe they didn't like me switching to an unlocked phone? Is there a number to dial that will reinitialize my account/connection? Or perhaps another APN I can try?
C) Or does this sound like a radio issue? Or a ROM issue?
You can look at your connection information if you open the phone dialer and enter in #*#*4636#*#*. Then press on phone information and at the very bottom you can force "H" only, so it won't switch back and forth between 3g.
You can also turn off/on the radio on the same page. Plus there's a load of connection information at the top.
This was a huge thing for Toro users, it seems.
Haven't heard as much on the Maguro side.
But if your situation is the same, it's a hardware issue.
If you flash stock (and maybe try swapping in a new SIM card) and it still does it...get it exchanged.
The switching between 3G and H is by design. T-mobile phones don't show the change but it's happening. (Marketing)
As far as data drops go. Is it completely dropping or just buffering?

100% dropping. All bars completely disappear and it's just left with a black blank triangle of no bars, even when I'm in an area of full 4-bar coverage. After a long while the bars reappear, and then after a while, the 3G/H comes back and data is reactivated.
And then it happens again a few minutes later.

What are you running and which radio?
There was a data drop issue on 4.0.4. I haven't had the problem since moving to JB

The radio you are running is XXKK1 which is a very old radio. Perhaps one of the first.
You should update to 4.1.1 and flash the newest XXLF1 radio.
Hopefully that will solve your issues.

Ah I see. Is it feasible that these issues could be caused by an old radio?
Anyway, does this 4.1.1 ROM and radio look like the right one to flash? http://forum.xda-developers.com/showthread.php?t=1737849
Its definitely possible. Could be a mismatched ril issue too.
Yep that ROM and radio are correct.

Hey guys I've got the GSM version and every now and then my signal bars turn grey, this is with full signal even showing 3g buts its grey and won't call out or load data. I'm not a twit and understand that phones loose signal its just strange it comes back randomly also. Very annoying.

grey full bars
i dont have a technical response to this question other than i only notice this during times of transition between either booting up the phone or switching to wifi on or off equally.
The phone usually checks to sync when it has been on standby and you then hit the power button. If you theoretically switch between wifi and 3g/4g during this time it would force a transition which could yield a situation as you describe.
This happens to me too sometimes. What network do you have?

You have to find out the true reason why your connection is being interrupted. The bars going grey instead of blue is just reflecting the fact that your connection isn't persistent and you don't have a full sync with Google.
Blue bars = connection to Google servers
Grey bars = no Google servers

When you open the browser does it say that there is no network coverage and you have to turn off the airplane mode?
I was having the same issue with 4.0.1, I was getting disconnect from the mobile network almost every 2-3 hours and the only way to get online again was to do a reset. But now with 4.0.2 everything seems to work fine.
My carrier (Simyo in Spain) is a "virtual operator" (MVNO), so I'm thinking that the issue was somehow related with the “data was disconnected due to roaming” bug in 4.0.1.

Hello,
This thread kind of died down but it is very important. Here is the issue logged by other users with Google. http://code.google.com/p/android/issues/detail?id=22503
Has anybody managed to find a fix?
I called Samsung yesterday and they advised me to return the phone. I don't feel like being without a phone for 2 weeks. Besides it is sort of proven that it is a Rom issue (am I correct?). What do you say guys, shall i send it to Samsung or wait for an update from Google? The problem doesn't happen very often, every once in a while. I suppose this is why the battery runs out pretty quickly as it tries to connect to a network too often. And when it doesn't establish connection it goes to Airplane mode.
Any more comments on this issue?
Hello,
I am running AOKP JB v1 on ATT Gnex. I havent installed any other kernels or radios. My issue is that, while i have full coverage in an area i know i have data, while my signal bars show full with "H" above them, i cannot get data. Cannot send picture messages or go to google market or use browser. I think i need to flash a different baseband or radio but i have no idea which one i should be using or what is compatible. Can somebody please point me in the right direction. It is rather annoying to loose data constantly.
Well I really need help now. I flashed a radio but obviously it wasnt meant for JB. I have signal enough to text and make phone calls but no data at all now. It shows all grey bars with the H above it. Can anybody link to a working JB radio/baseband for GSM please?
I believe i should be use 9250XXLF1 but i cannot find a download for it
Edit: Found it here:

Try going back to stock completely. I do think its rather a network issue. Do you have the correct data plan for it?

I have been using the UGKL1 radio on ATT in Northern California - has worked well for me. Obviously, radios are very dependent on location but this radio was a big improvement for me.
They changed something with the network, allot of users reporting issues of data drops because its switching from umts to hspa and hspap constantly.

I see it constantly changing between the listed signals although the status bars show full w/ "H" above them. Tried multiple different roms. I switched from lumia 900 to this phone so my plan is good up to LTE. Shouldnt have an issue w/ that. Would flashing a different radio help?

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.
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.

LEM

LK3 -------------Works but only 3G data.

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.

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.
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
