[Q] N4 Randomly Dropping Mobile Signal - Nexus 4 Q&A, Help & Troubleshooting

Good day all,
I got my N4 a few days before Xmas 2012. It's the best Android experience yet but I have a big problem:
The signal on my phone drops randomly when I'm on mobile internet (H and E -- haven't seen 3G yet). Randomly means sometimes once in 30 seconds or once in 5 minutes. The signal disappears for like 5 seconds and then pick-ups again and connects to the internet. Wifi is not turned on.
Has anyone had this problem or can direct me to a thread that discusses this? It's really annoying since I sometimes do remote access (teamviewer, etc) via mobile internet and have subscribed to an unlimited use of mobile internet which is quite expensive in my country. My money is wasted if I don't get constant connection whenever I need it.
Is it a hardware problem or a software problem that the next OTA update will fix?
I previously had an HTC Sensation (in the same locations that I get the dropped connections now) and there weren't any problems at all.
I've tried Googling but I have come up with nothing. Replacement is not an option since N4 is not yet officially sold in the country and I just got this from a local vendor who imported them. I do have warranty and I can give it to LG to get repaired if it is a hardware problem but I need to be sure first since it will take weeks for it to get assessed and repaired.
ROM: Stock 4.2.1
Carrier: Globe (Philippines)
Thanks!

Phone - The operation failed.

Quite often these days I am getting the issue mentioned above. Even soft resets do not seem to help. Until I reset a few more times.
What might be the cause of this? Thanks.
Hope someone might be able to assist on this. Thanks.
I'm also getting this message nearly every time I try to make a call. The phone then looks like it resets the connection with the cell tower and it successfully completes the call on the second try. Then the next time I try to call someone else it fails again. I came to this forum to see if anyone else has experienced the same problem.
Hey joej, I found out what might be causing the problem: make sure that your ActiveSync is closed before you try making a call. That fixed the problem for me.
Also, here's a quote from an email from one of my coworkers:
"Your Tytn was probably trying to dial a data connection at the same time that you were trying to dial voice and so it has to cancel the data request before you can dial out. There is a registry tweak you can do to the Tytn to keep the data connection always active when the phone is not in use and this may make it less frequent that you would have a problem
Activesync is supposed to stop when your data connection is unavailable. If you are making or receiving a call on the TyTN (or any GSM phone) your data connection will not be available and therefore not run. Do you have a lot of 3rd party apps running at startup as well? I have rarely had a problem with my Tytn and never during a call unless my battery dies on my BT headset mid call and then the device may get confused."
Hope this helps!

thanks for the update, i however am experiencing this issue once in a while and it is not with the activesync running nor a data connection going on. ugh..... guess mine is odd
Me too
Thank so much for the post count me in there too. I am southern central PA and just last week this started happening to me too. I have an 8525.
I have no acrive data connection nor any apps running that force a data connection. Every morning I have been resetting the phone 5-6 times before the freezing stops and it works. So annoying.
I am suspecting it is a network issue with cingular and them upgrading to 3g in my area. I suspect it as I had to travel north this week and discovered 3g coverage in Harrisburg so I am betting that is it.
I feel your pain and I have no fool proof thing to do on the phone to fix it. But man the phone on the 3g is fantastic.

yup, everything rocks in it except the phone functionality really needs to be improved to be more usable.
do you know how i can use the phonepad to do t9 for replying SMS ? right now i am finding it hard to do so as i need to use the normal input methods which is not as easy as a normal cellphone
omg I'm from Singapore using Starhub think I'm having the same problem too. Dopod 838 pro.
A soft reset works for me, but very frustrating coz you dunno whether you are missing calls - the screen shows mobile is up with signal and all but people can't call in.
Just started happening to me past few days but then again I just took over the phone from a friend who bought it 3 months ago (latest batch)
So frustrating. ... seems related to the activesync.. but then again still happens when activesync's not involved.

Same here anytime Cingy plays with towers, have you ever got a message stating the call can not be completed at this time? Been getting that one lately as well.
I think that it could be an issue with the phone heightened by the nature of the cell network.
I am wondering if the phone has issues handing off between cell towers as I have the band tab active and there are freq choices so I wonder if the phone even on gsm has some issues dealing with hand offs.
I locked it on gsm and still had issues with the phone. I locked it on 850 and still had phone issues. Put it in auto for the freq and still had issues.
On the U network on Cingular since its the only one the phone is excellent. Data and voice work great. So it will get better in the US for us on Cingular. But man its going to be really annoying during the roll out.
I'm on T-Mobile and I'm seeing this problem as well. (It didn't go away after closing ActiveSync like I said it did earlier.) The weird thing is that this wasn't a problem until about a week or two ago; now all of the sudden it's happening constantly.
Also, I just installed the newest HTC ROM (1.35.255.2) yesterday and now my phone has started to drop calls. I've never had a problem with dropped calls in the 2.5 years I've lived in this apartment.
Ain't technology grand?
Well things have not improved for me. Today after 8 resets the phone finally settled down and did not freeze and was able to get on the network. It has been terrible for me the last 2 weeks...
I removed the eten dialer skin I was using. I wanted to make sure it was not due to replacing the Cingular phone skin.
We shall see tomorrow if the phone is able to work without multiple resets..
If not it is off to a hard reset and re-load to see if that improves it any...
I have taken the plunge and did a hard reset plus reinstall of everything. I had the same apps installed again and the problem seems to be gone now. *touch wood* hopefully this doesn't come again... a restore takes too long. I have also installed Sprite and did a full backup of the phone including the memory card just to be safe.
This problem started for me this morning. (NYC/NJ Area - USA). I did a hard reset (actually, two) this morning, and it didn't fix it, even when the phone first finished the initial load (in a virgin state). Then, around 11:00am, it began to work again. Now, it's about 6:30pm, and I need the phone to call home to tell them I'm gonna be late, and it's out again. Seems like it's something not to do with the phone, but with the network (I hope). It won't connect in GSM, UMTS, or AUTO modes, FWIW.
Oh well, sure hope it doesn't takle two weeks to "go away".
returned
Well I returned mine. Did the warrenty exchange. So far so good. No freezing and the phone seems to hold onto the network ok now.
I truly believe mine was defective. As the phone would show searching and not connect to the network.
I think that not being able to make a data connection is a network issue as it clears up in a few days.

also in the same area, experiencing similar problems within certain specific locations. Noteably these are locations that I get SPOTTY UMTS service, so I assume a tower upgrade is in progress or something that is causing this. Where I have full umts service, the problem does not occur.
at times i have signal, but calls don't come through (rings to calling party, but goes to voicemail before my device rings).
This is something related to 3G because when the sim is put in a blackberry 8700c, everything works A-OK.
Glad to know i am not alone in this
I have similar problems. Especially in the university of Hannover. There is UMTS. Since a few days Data Connections via Active Sync don't work.
Before I had problems with calls. For example freezing during call.
And of course in the university and on other places I have often to do calls twice.
I called O2 for that problem. They are upgrading the cell around the university to HSDPA.
Hi to all !
I had the same problems, then i removed the microSD card and the problem was gone. Now i am testing the phone without miroSD card. I forgot to say that i had the problems with boot too(No GSM) and now it boot perfectly.
Best regards
O2 XDA Trion (dopod rom)
I finally had to return the phone under warrenty. It degraded to no gsm all the time fresh from a hard reset with no mem card. The new device has been flawless radio wise for a week now.
Problems with XDA Trion SOLVED !!!
Hi again !
The microSD card was NOT the problem ! I tested the phone without SD card but that was not the problem. Then i go to my provider and change the SIM card with new one (the old one was very old so i buy new one) and wauuu it works. The XDA TRION needs the sim card with UMTS suport then it will work fine. So far NO freezing at all. I will let you know in a few days if something strange will hapen.
Best regards
Hi, to all with the problem “The operation failed” when trying to make a call:
Try to switch off bluetooth (specially if you are in UMTS (CMDA) network) and then try to make a phonecall again.
For me this helped to solve it.
First I also thought that it’s only a Provider network problem (I have 2 different providers, with one it works, with the other I have the “operation failed” problems).
So it is 100% a phone software problem. (Shame to HTC)
Give feedback if it helped you too.

Strange internet problem on T-Mobile G2

Hi,
Not sure if it’s my handset or for everyone in general in the UK on T-Mobile network.
Strange but true. While traveling, internet just doesn't work on my G2. Whether on the popular motorways such as M1, M25 or on train where T-Mobile coverage is very good, I get one or two bars the internet just doesn't work. It throws up error messages that it cannot reach the host it’s trying to connect meaning no data connection. It’s definitely not the coverage problem. Something to do with the phone as I never had this problem on my Nokia E71.
I called T-Mobile helpdesk but they just don't know and don't understand. Is anyone having the same internet problem while traveling? Any workarounds? I don't want to change the firmware as I can get a replacement from T-Mobile (I suppose) if I'm persistent with them. If I change the firmware, it may void the warranty as my phone seems to be faulty.
Any recommendations or workarounds?
Thanks in advance.
Hari
I'm getting something similar some of the time. I'm waiting for the official SW update in the hope that this will be fixed.
Yes, same problem here sometimes. I wonder if it's got something to do with the phone maybe?
Do you mean WiFi or 3g? One of the best things for me was sitting on eurostar watching the gps marker shoot across the screen as the map also was updating... that was a month ago, though, couple of days after I got the phone.
So do you ever get a connection.
When travelling in a car mine seems mostly ok.
It does lose internet connection sometimes when moving from a 2g to 3g signal and can take a couple of minutes to come back.
You could try forcing a 2g connection only to test if that works ?

Problem with Hero on T-mobile UK

Hi!
I have the handset for few weeks and for couple of days I have a problem at the times to connect to internet. Look like Hero try to send data but there is problem with downlink. Some times when you turn off and on the internet it seemsd to be working at the times ....
I have already updated the software to the newest from T-mobile but still the same problem.
Any ideas ???
Thx
Well i have the same problem with Telus in Canada I thought it was a network problem but now you have me wondering if it is a defect.
same here on T-mobile UK in London... I noticed a reboot solves the problem most of the times... But I am not too sure why it happens in the first place. I noticed it seems to happen in very crowded locations rather than when I am somewhere with not too many people. Every time I install a new radio I hope to see the problem disappear, but it never really does. Quite disappointing... :-( Hope for a fix in the near future though.
I've been getting the same problem.
The HSDPA icon will change to 3G, then the connection will stall completely. I'll have to put the phone into airplane mode and back again to restore it.
T-Mobile tried fobbing me off with my contract didn't allow high speed data, to the next person telling me to just try it in a different post code, they're not aware of any problems, with finally the most recent tech support person telling me T-mobile is aware of a HSDPA and 3G problem that should be fixed in 5 days, please bare with us.
W*nkers.
I definately feel like I've bought a red herring with this phone. Or should have at least got it straight from HTC. I'm reluctant to put a new ROM on there so soon after getting it.
In Canada it seems like it is a network problem. I went out of town about a hour and data worked, came back and it did not work. Phoned and was told it is a network issue and to bear with it they are fixing the problem in a couple days. It seems odd that the same thing is happening in two different across the ocean at the same time though. Who knows if it is the same problem though.
I have the same issue with Orange till this weekend when the phone won't work on 3G at home at all even though it gets a signal. The 3G netwrk is down in my home cell area for a week so I'm stuck on 2G. 2G speeds on some sites are even better than 3G as it doesn't stall on the downlink.
I had this issue but it seems to be OK now. Probably a network issue.
Hi !
It look like the blame is the simcard
Someone suggest something and it give me idea. I have put bit of paper betwen simcard and the thing that hold it and then just a bit on top of it and does seem to have problem. It look like Hero have very sensitive simcard holder
Good luck
All fine here!
I'm in south London, UK and never seem to have a problem with the internet. I'm extremly impressed as on my bus journeys I frequently stream like radio without much problem. I hope things improve.
I'm also in south east london
I get awesome speeds with HSDPA, but not so great with 3G.
I generally stream from last.fm and it pretty much stalls when on 3G. Web-browsing on 3G alone is also not that great for me.
This sounds like it's more a problem with the coverage than the phone though (althoguh it's interesting that a reboot/re-enabling mobile net fixes it).
Couple of things to try:
1 - Download a speed-test and see what speeds you're getting.
2 - Check coverage here: http://www.t-mobile.co.uk/services/coverage/street-check/
im having problems to , i spend half the time on Wifi and only use mobile network if im out and about, but im barely getting 3g and im in heart of england (birmingham)

[Q]Losing data connection

Hi I wonder if anyone is having similar problems or has any suggestions. I recently got the omnia 7 on Orange.
The problem is that overnight my phone will completely lose its data connection. I will still have voice and text services. It will stay without a data service until I either reset the phone or re-scan for available networks. I've rang Orange and they've referred it to their tech department. It seems strange though as before i HD no problems on my touch HD.
The problem seems to happen between 1 and 2 am every night. According to the last successful email sync. After the connection is lost I have no data symbol displayed next to signal strength either.
Really frustrating
Similar thing happens to me, but it loses connection maybe after 2 days, sometimes after a week.
I never found a solution to this and so it still happens.
Only happens in my flat overnight, well most nights. Some nights it won't happen. I've only had it happen one other time away from here which was travelling up to Scotland thorugh some poor reception areas.
From this I concluded it is a network issue, something to do with the data connection shutting off. More specifically something to do with the crossing between Orange and T-Mobile's network since they started the sharing / roaming.
If i stay in an area with good signal it never happens.
Agree, cause usually I notice this problem when data connection switches to Edge.. I was hoping NoDo will solve this... but no

[Q] Note4 loosing data connection

Dear Friends,
has some who owned note 4 faced a continuous loosing data connection?
I have been facing this issue for the passed one week till now, I have tried to format the device but the problem is still there, I have not done anything to the device.
I called my ISP and they said that there is no problem with your sim card.
please advise if anyone of you had similar issue.
thanks

I've just experienced this today on my 1 day old N910C, I'm on 4G and suddenly earlier today my 4G mobile data indicator disappeared but it still showing the usual signal bars. Tested browsing, no mobile data it said. Tried putting it to Airplane mode then back to normal, didn't bring mobile data back. Rebooted it, then it's working again.
Not yet to see this problem but my friend's Note 4 had this problem. In the end he brought it to the service center and they replace the mainboard. Still wait and see if it fixes the problem.
it happened me before on other samsung devices too. generally an update fixes it but could be hardware problem too.
Hopefully its software related ive seen a slew of note 4s have this issue both variants included.. its annoying to say the least
Hi, I just got my phone, may i know whether you guys have resolved the issues?? i need to turn the flight mode on and off a few times to get the data connection back online
I sent back to Samsung services center, it seems that they said they reprogram the software. Will observe and see how it goes.
Mines all good now few updates and new provider all good ?
Hi guys, I've experienced the same issue, the mobile data connection suddenly drops (H+ icon doesn't disappear but the download arrow is off, meaning that there's no inbound traffic) and the only way to have the connection back is to to disable mobile data and than reactivate it. I've updated my phone, I even tried to install firmwares of other countries (different csc) and to change carrier but I haven't solved the problem (same situation on my friend's N4).
Hi
i had a problem with wifi. weak or no connection.
100% solution for my note:
go to settings=>location=>use GPS ONLY.
perhaps it solves also your problem...
Hello all! Just faced the same problem! Losing internet connection. Did anyone find a solution?
Note 4
Yes this is BS. If I go to a place with no data service, then travel back to a place with data service, I have to first disable then re-enable the "Mobile Data" toggle in the settings. It's such BS that this is happening. My note 3 NEVER has this problem. Starting to dislike Samsung's buggy releases.
Same issues..

Any news on topic? I'm facing with internet on mobile connection, even if bars are full and LTE sign is visible.
