Sorry for fullquote, but this is exactly my Problem. Even with factory reset and only whatsapp and nova installed

I can replicate this everytime. After a reboot I only get data for a minute, untill i'm loading a picture or something other with a bit bigger data. Only reboot fixes it.

This is a total other Problem, than the one with the kernel fix, where they loose data after a while in standby, where airplane mode fixes it.

I will try it with the log.

By the way I already called my carrier (Vodafone, I cutted the SIM by myself) and they said they reconnect something to the SIM. But didn't help.
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
Here's a quicker fix than reboot. Go to mobile settings-apn. Click on current apn as if you want to edit it, don't change anything and go back. It will reload apn.

[Nexus 4 Q&A, Help & Troubleshooting] williamj1:
I can confirm I have this issue too. I'm running completely stock software, not yet rooted.

I haven't been able to locate or recreate when or why it happens. Generally though for me it is when mobile data hasn't been on for a while.

I get two issues. The most common is that it displays the H icon but it remains grey and doesn't turn blue. But more frequently recently its turned blue but still won't give any data. I've triple checked my APN settings and they are all A ok.

I'm on Giffgaff / O2-UK btw.

Edit: With regards to fixing it I haven't found a solution. Turning mobile data on and off does nothing for me. Turning the phone on and off also seems to do nothing. Aeroplane mode works inconsistently, sometimes it solves it other times it doesn't. Generally, I just have to leave the data on, go away and after some time, hope it will have connected properly to data services.

Time for an RMA my friend. Most phones don't have this issue. I can say one of my previous n4s lost connection all the time. I couldn't stream anything or download large files. No problems with the other 3. Crazy thing is the one with the data drops got me the best battery life. Perhaps because its never using data, its not getting the drain other phones are getting.

I get the same thing, although it's very occasional, on stock rom running on giffgaff in the UK. I also had my wifi refuse to go on earlier :/
[Nexus 4 Q&A, Help & Troubleshooting] Caumen:
My connection began to fail yesterday just after flashing the first update of AOSPA and since then I have been unable to install the second one, because the connection is so poor and unreliable.

I'm on 3 network in Denmark so I don't think it's a provider issue, and more an issue with software (which a few of you guys seem to think too)

Can't wait to get this solved since today I was going to brag about my phone to all my iPhone mates.

Hey.

Just reporting. Installed GetRil from the store and Reflashed the ril. So far so good.
[Nexus 4 Q&A, Help & Troubleshooting] kresk:
So after a few days I'd have to say that my signal has been more consistent. I hadn't had one of those weird signal drops and I think my battery has improved, though I can't tell for sure. Have you noticed any positive or negative changes with the battery? Also, when I refresh gmail manually it seems like it takes a second or two longer than it used to. There may be a side effect for loading web pages sometimes as well. It's like it gets held up for second in the beginning and then it loads almost instantly. I can't remember it getting held up like that before. Not that the loading is taking forever in either case. I think it just may be acting a bit differently. Now that I got pretty used to this setting. I am going to go back to the old one for a day or two make sure these changes aren't all in my head.. I'll be sure to update this post with my findings.

No ROM/Kernel combination ever fixed this. And by the way, mine is extrem. I can't load Facebook app. Every time I want to use whatsapp, I have to restart first.
[Nexus 4 Q&A, Help & Troubleshooting] williamj1:
I think its partly to do with what network people are on. If its a main network, e.g. vodaphone or O2 then it seems to be fine. If its a secondary network, e.g. Giffgaff which runs on O2, there seems to be stability issues. This seems to be the case for everyone ive spoken to so far, including people in the US.

I also think its something that Google messed up in 4.2. I used to have this problem on my old HTC Desire, on ROMS where there were poorly implemented quick settings in the notification bar. Or when I had widgets on the homescreen which controlled data. For example, if I had mobile data on in settings, but off on the widget, it would totally **** it up and it would just keep turning on or off, or it wouldn't change status at all. I'm wondering if when Google implemented the quick settings in 4.2, its related to that. But then by my own logic, im not sure that makes sense because the quick settings doesn't directly control the data like say brightness controls screen brightness. tapping data in 4.2 quick settings only takes you into settings. There are still two locations where you can turn on and off data .... in the mobile usage menu, and in the mobile networks menu. So maybe my theory isn't entirely rubbish :confused::victory:

How many people here had an older phone before, which took normal sim cards?

I cut my sim down myself, im wondering if maybe I should order a new micro sim rather than my botch job on my old normal sized one? :confused:

I'm going to LG and let them fix my phone. I've suffered from it for almost a month. :crying:
[Nexus 4 Q&A, Help & Troubleshooting] tengen:
So my data has been pretty much rock solid the last few days. While I don't know exactly why that is (it could just be good luck, I suppose), the only thing I did differently was manually create an exact copy of my APN - same settings, same everything - and switch over to it. A few reboots later and data seems much, much more reliable (haven't had any drops in days).

I doubt this is a true fix for the data issue (like I said it might just be luck), but it might be worth a try for those of you who are still having issues. Takes two minutes to do.

I'm on T-Mobile btw.
[Nexus 4 Q&A, Help & Troubleshooting] lowrider262:
is the data drop issue pretty much only happening with T-Mobile users? reason I ask is cause I was on straight talk at&t for the past month and I wasn't having any issues with data dropping. but ever since 2 days ago I switched to solavei (a T-Mobile mvno, for those who don't know) and I get data drops like crazy. the kind where it shows I have full 3g/h connection but pages just won't load, I have to keep refreshing or toggle airplane mode... its really frustrating. I think a lot of people are thinking its software/ hardware error, when really its just crappy service
[Nexus 4 Q&A, Help & Troubleshooting] BigDig:
T-mobile is doing a lot of work on their network now- LTE, Reframing to 1900mhz e.t.c , so maybe they are working in your area too and that`s why some people see some kind of data outage and then it goes away.....
[Nexus 4 Q&A, Help & Troubleshooting] hvrio:
Hi guys,

I'm here way over in the Philippines and am having the same signal drop issues so I doubt it's a carrier problem.

What happens with my N4 is that the signal totally disappears -- no bar at all. I'll be at H then everything will just disappear, reappear after a few seconds, have full signal bar, then have H appear then have the signal bar turn blue meaning it's connected again.

I've tried placing the phone on top of the table and have it run youtube videos to test the signal drop and I noticed that it drops less (or none at all) if you just leave it alone and drops more if you hold it in your hand with your palm at the back.

Any thoughts on this? I figured this can also be the cause of the problem or contribute to it since some phones are known to have death grip issues.

Had no problems whatsoever with mobile internet when I was with my HTC Sensation. Using the same sim card and in the same living and working areas.

Thanks!

[Nexus 4 Q&A, Help & Troubleshooting] sailfast:
Have just been watching it and it seems that it changes towers with every data drop.

[Nexus 4 Q&A, Help & Troubleshooting] eric_son:

I'm on SMART.

Since you're on GLOBE, and I'm on SMART, I guess we can safely assume it ain't network provider related.

It also happens to me in EDSA, between Kalayaan and Pioneer.

[Nexus 4 Q&A, Help & Troubleshooting] _ice_:
Data drop was a huge issue for me on certain new kernels.

I am highly certain this is a soft issue myself. I have only had 2 data drops in 30 hours approximately w below combination.

Phone: rev11

ROM: aokp Jan 8 & 13 build

Kernel: bricked kernel latest stable (Dec 24th)

Sim/ network: purchased microsim/ T-Mobile contract

Location: Houston

Any faux, harsh, Franco kernel (beta/ stable has major data drops)

On another note: on those above kernels data takes long time to initiate. For instance I type a URL. Data goes from 3g to H, arrows appear, 3 second delay, URL finally loads. This doesn't happen in brick kernel. Also sometimes resetting the APN on those kernels seemed to help temporarily.

I recommend the following:

1. Purchase proper Sim card (no cuts or ghetto rigs)

2. Try different kernels (took me about 7 kernel flashes) reset APN upon boot

3. Test in different areas if you can

4. Test network connectivity on another phone to check for area outage.

5. Revert to stock, lock boot loader. Pull Sim out put back in, reset APN, reboot phone.

6. Call network provider ask if there's area outage or reported outages

7. If all else fails, you have a faulty hardware (RMA or warranty at this point, though I strongly believe its a software issue)
[Nexus 4 Q&A, Help & Troubleshooting] Pflunz:
I am pretty sure it is hardware related.

I tried different SIMs, different ROMs, different kernels, different carriers. In the end I tried it completely on stock, with locked bootloader, factory reseted, no apps installed, and I still had this. Since we are only just a few over the whole world with this error, it should not be software related, because erverybody got the same software, why got just we the error?

I put my SIM into an other nexus 4, worked like a charm.

[Nexus 4 Q&A, Help & Troubleshooting] undercover:
I'm sure this is software issue. I just can't work out what connection there is between us having this issue all over the world. If it was hardware fault, resetting apn or going into airplane mode and back wouldn't revive it. Also, I ran some logs and it looks like phone had problems loading apn, hence not connecting.

If it was hardware problem, people with Gnex wouldn't have this issue after updating to 4.2/4.2.1.
[Nexus 4 Q&A, Help & Troubleshooting] Pflunz:
I sent it to LG. Should be there tomorrow. They said it will be there for less than 24h.

I already uploaded a log. There you can see it looses data connection, and tries to reconnect. Enabling airplain mode or reloading APN didn't fix it to me. Nether an other SIM (same carrier, other carrier, other frequency), nor any other software (also stock 4.2 downgrade) fixed it.

No problems with my SIM and same APN settings in any other phone or the nexus of a friend.

Already called carrier, they said they reset something with the SIM. didn't help.

I hope LG will give me a summary of what they did.
[Nexus 4 Q&A, Help & Troubleshooting] hvrio:
I just reset my APN and entered my network's APN manually and pointed my mobile internet to connect to that.

Haven't seen a drop in signal for the past 30 minutes. Usually I get the drops within 5 minutes.

I think this is it. Keeping my fingers crossed.

Give it a try and report back.

EDIT:

I spoke too soon. After 10 minutes of posting the signal dropped. BUT it didn't go out completely. I can still see the signal bar and my phone is still sending out data (up arrow) but not receiving any data (down arrow) and signal bars are grey, not blue. This is in contrast to what I had before which was that the signal bars completely disappeared as if there was no cellular reception.

I'm pretty sure this is a software issue related to APNs or how the phone handles it.
[Nexus 4 Q&A, Help & Troubleshooting] _ice_:
Yours could be both software and hardware issue. Most of us are experiencing software APN drops. In your case it may have been a defective radio or bad shielding issue. Please be advised that the n4 already has bad shielding problems hence the static in all n4's ear piece. Also iPhone 4 or 4s (can't remember) had the same issues. Where their data would drop. It was determined to be poor shielding that's when they issued those band aid/ sticker things for a temp fix.
[Nexus 4 Q&A, Help & Troubleshooting] undercover:
C'mon people, keep dumping data here, no matter how irrelevant you think it is. Thing is, while i am sure this is software related issue, i'm surprised everyone doesn't experience it. We need to find a common denominator here. Keep throwing any ideas, fixes, weird stuff, guesses in here.
[Nexus 4 Q&A, Help & Troubleshooting] chrisgtl:
I'm on o2, with brand new micro sim and still get the drops. Using franco kernel #34.

I get drops on wifi, google talk often loads with me 'offline' and once I go blue from grey and reload google talk I'm back 'online'.

When my phone is in screen off status and im using my laptop for google talk then phone doesn't keep up with the conversation. Once I wake my phone up and open google talk there is a short delay and I see the conversation been updated.

I'm convinced this is not hardware at all, google have a serious bug in the code somewhere.
[Nexus 4 Q&A, Help & Troubleshooting] eric_son:
I hope so too.

Anyway, here's my input.

It happens to me when I am in a place where the signal of my provider is low. (My office, basement parking, stuck in traffic in a tunnel/underpass).

Here, I will notice my phone desperately trying to connect - the signal bar will show the small up arrow.

Eventually, it will give up.

Once it gives up, it will no longer attempt to reconnect, even when I enter a place where i know I get good signals.

At this point, any of my apps that require data connection will promptly report "no connection" when I try to make it access the web. I won't even see that small up arrow appear on the signal bar, even if I get a full signal with "H".

I think that there is some kind of memory leak that occurred when the phone was busy trying to re-establish connections?
[Nexus 4 Q&A, Help & Troubleshooting] lowrider262:
FWIW, I put my phone completely back to stock (unrooted, stock recovery, relocked boot loader) and my data drops have decreased dramatically, almost nonexistent now. I was running CM nightlies before this and tried various kernels including stock and the drops were becoming unbearable. Think I'm just gonna stay stock fore as while till this gets sorted out.

Chiming in here:

Hardware: rev11

ROM: AOKP JB Milestone 1 r1

Kernel: Mat1x 5.0

Network: T-Mobile

Location: Northern Virginia (D.C. Metro), USA

Description: 1 + 3, 3 most often but usually doesn't work again until I toggle Airplane Mode or reboot.

I HAVE to believe this is a software issue. Issue #3 is pretty close to the bug reported here:

http://code.google.com/p/android/is...s Owner Summary Stars&groupby=&sort=&id=40065

The issue was created for Wifi data drops, but it definitely affects myself and others for carrier data connection. AND it affects multiple devices (N4, N7, N10, GNex), so the only common denominator here is Android 4.2.1. Most people in that bug report didn't experience these issue until the 4.2/4.2.1 update.

In the past few days I found a radio thread here:

http://xdaforums.com/showthread.php?t=2087227

Yesterday I tested with the .27 radio and today with the .24 radio. In both cases, data drops on HSPA+ still occur, albeit a bit less frequently. Signal strength is stronger and data speeds are better when I'm at home, but the battery drain is much higher with both radios than the latest .33 radio.

Having fewer HSPA+ data drops with the older radios also makes me inclined to believe that the radio is A culprit in this equation, but not the only one..

Okay I think I might have figured this out

---------- Post added at 11:03 PM ---------- Previous post was at 10:44 PM ----------

OK I think my fix did work

I'm on paranoid android 15th build with pie and I'm running faux's kernel 4 r2, on tmo network.

Now this is a trick I used to use on my old phone when it had data issues.

I went in to APN settings and created a new one called tmob (name doesn't matter) and only inputted the APN line which was:

epc.tmobile.com

And selected tmob in the settings

I've been having intermittent data problems and when I had a fresh flash and and clean wipe I was good for a day then I ran into a big stall after turning off WiFi and I decided to try this trick and it picked up the network really quick.

Now I've been running this apn for about 2 hours and its working good as far as I can tell no issues data picks up and switches from 3g and h really well and fast I'm happy hope it helps everybody good luck :) :D

You may be a life saver! It hasn't been long but things are looking good so far.

I notice that my phone now sits on H, and then ramps up to H+ when transferring data, as it should! Before it was always on H+, sucking my battery dry when at home because that tower has the highest dBm.

The apn settings posted a few days ago didn't help, but so far, the "blank-except-name" APN has! I'll keep an eye out for data drops. Thanks!!

Well, I'm on a different network. However, I did try something similar and so far nothing. The only thing that seems to do something to it is to Reflash ril, but that brings new issues.
