[Q] mobile data randomly disconnecting - Nexus 4 Q&A, Help & Troubleshooting

Currently using Omni rom and hellscore kernel but I had this problem in all the roms I've tried.
My phone randomly showing H signal instead of H+ and there's no Internet connection sometimes it loses the phone signal completely and the service is not available.
The only way to fix it is rebooting or turning airplane mode on and off.
Been having this problem for a long time and would really appreciate your help.
Do you have any idea what's the cause for this?

H+ only shows up when you are actively using data- it's a feature of fast dormancy. Completely normal.
As for data drops, what exact symptoms are you experiencing?

Wireless and 3G icons showing at the same time

Hi
I can tell that the phone is using wireless due to the speed. Its just a little annoying.
Anyone else have this issue?
Masters stock 2.3.3 deodexed (rooted) with Netarchy 1.2.7 cfs @ 1.2
the same thing it show before and after i root my NS
same here.
with 2.3.1 and now 2.3.3
Yeah it's happened to me. Just toggle WiFi off then toggle it back on.
Haven't had that problem. You should try flashing again. I just heard of that problem in 2.3.2

Its my understanding that this is as a result of an app which needs to use wireless data specifically from a mobile network so it momentarily turns the mobile data radio on and then turns it off when its done.
i have only google apps and the 3G was on and the wifi in the same time ....
I think this is the issue:

Star the issue and post in the thread - looks like Google are starting to show an interest in it.

T
and I have another thing! when i want to start mobile data it just won't start. to solve it I have to reboot my phone!
anybody else getting this?
Nexus S, 2.3.3, gri40, Vodafone Romania!
Sometimes turning on airplane mode and then turning it off again starts the mobile data for me. Give that a shot Bikers.
Are you guys receiving an mms at the same time? On WiFi when receiving a pic message the phone is forced to use 3g data to connect to the carrier server over 3g only to receive the pic. This is the Only time I've ever seen WiFi and 3g at the same time.
This usually happens to me when my wifi is out of range

Up until yesterday I was running 2.3.2 with the XXKB3 radio. I updated to 2.3.3 and got the XXKB1 radio. As soon as I connected to wifi, I started to experience this problem with 3g and wifi showing at the same time. So, I decided to re-upgrade to.the XXKB3 radio and I no longer have the problem.
The instructions on how to upgrade your radio are in the development section. Its definitely worth a shot. Yesterday I was not only losing wifi, but my 3g was going out also and I had to reboot my phone to get my 3g working. That doesn't work for me.

how long do both icons display together? is it only for a few seconds, or do they stay on indefinitely? if only a few seconds, it could be a wifi bug where its disconnecting then reconnecting in the span of a few seconds, so in between the 3G kicks in only to turn back off when wifi reconnects.

It is sporadic. Sometimes it comes on every 30 seconds or so then turns off. Other times, it is on indefinitely..
I read some where that having "supl" in your APN settings under APN Type might be doing it. maybe check that?

Problems with mobilenetwork

Hello guys, i got my Note a week ago, and i have had som problems with the network operator signal. The problem is that phone loses signal every day, and after restart the signal comes back but after (30-40 mins) sometimes longer the signal disapears. It is very annoying. First i thought it was a problem with the sim-card but after testing it on another phone it worked just fine. I never had this kind of problem before, and i dont no what to do. My operator is (Telenor Norway). Thanks for the help.
PS: Sorry if my english is bad, i tried my best
Is it phone signal completely or just data? I have had data connection problem with my SGS2, with factory reset it went away. But I always had my basic phone service.

I had the same issue (only with data connection) and solved it choosing manually the network instead of automatic in settings. No loosing of signal in three days in a row. I hope it helps!
It is the phone signal completly, i did try to set up connection manualy but i did not help. Tho i did not try the factory reset, going to try it now and see what happens. Thanks for the both suggestions.

I have the same problem. Since the day I got my Note, I experienced both phone signal lost and 3G/2G data signal lost. Also tried factory reset and changing data to manual mode but still getting the same problem. Sometime it is the 3G/2G signal lost and some other times both phone and 3G signal lost.
The big problem here is that the moment the signal is lost, it will not automatically resumed. You never noticed it because the phone signal bars is still there running fine up and down. You thought it is okay but in fact no body can call you. You only get to notice it the time when you tried to dial a call out then only you discovered that there is no call signal. Too late - you may missed many important and urgent call !
To get the signal back, the only way is to soft reset your Note.
I get around with the above problem by installing an app called "No Signal Alert" it is free. This app will play a sound and vibrate when there is signal lost.
There's plenty of different radio for note. Try find them in the development section

Hi thehackersz,
Thank you for your feedback. I have done a search on the development section but all the discussion looks confusing to me. I do not know where to get started.
Please help !
what happen finally???i have the same problem with different roms and now with ics????is there any solution??

Phone sometimes disconnects when using WIFI

hi, sometimes when i look at my phone, usually after being on wifi the phone shows no bars.
sometimes it comes back on in a min, i tried airplane mode but it wouldnt work. so i restarted it and worked fine.
not sure why it happens, does anyone else have this? could it be due to some Wifi calling setting? not sure why phone seems to just cut off.
anyone have any idea why this may be happening?
does it turn off radio for wifi calling somehow or? just random.
I have a similar issue, but not equal. Sometimes, when I try to connect to the network I always do (home), it simply doesn't work. Scanning - disconnected - scanning - disconnect. Only a phone reset fixes this.
Sheep ROM 2.0
AbyssNote Kernel 2.5
I had a similar issue a while ago and sent Mine back to the seller but the seller claimed neither they nor Samsung could find a problem with the phone. Thankfully The seller sent me a replacement which no longer gives me this problem so it may be the handset, though it could also be the setting/Conflicting app. Someone reported here his problem Was solved after adjusting a w ifi regulating app
i have a 3-day old gnote and i started noticing this problem after i have my phone rooted. the wifi icon stays on but there's no internet connection. turning the screen off and waking the phone after a minute solves the problem but its annoying to be losing connection when you're needing it. i'm on stock KKA.

Not a user error so need to contact Samsung-don't think is anyway
I have a somewhat similar problem. When I am using wifi for somewhat long time, I am unable to connect back to my 3g. Or if I was on 3g connection and I move out of coverage area for a little more than 10 minutes, I can't reconnect to 3g. Only 3g connection has this problem though, everything else works fine.
If I restart the phone, I can reconnect. Setting to airplane mode and resetting doesn't help. Neither does resetting the mobile network operators.
Yes, the problem seems to be software related since there is no actual problem with receiving 3g/phone.
yesterday i drove back 10 hrs and streamed music/radio the entire way with only a few tiny interruptions in reception.
but often still if i just take my phone out of my pocket, the "phone" part will be off and usually turn back on within 1-2 mins.
but this is quite annoying since sometimes il literally be waiting for 1-2 mins to place a call.
my phone is "not" rooted.

[Q] defy+ data network woes

i have a variation on the data network problems, not as annoying as reboots,
but getting close.
normally i am on GSM only, as my data needs are low and it extends
battery life. for hours, everything is dandy. then i notice that
the "G" icon and the signal bar are not blue anymore (stock theme)
but grey. 'settings' say i am still data "connected", but in fact
data connection is out (the operating system thinks there is
data connection, browsers and mail clients keep spinning and
trying until timeout).
turning on and off wifi makes the phone try to connect to the data
network again. sometimes this works, but more often that not, i have
to switch to 3G mode for this to work, and sometimes even that does
not help, and i have to go airplane mode to turn the radio on and off
completely. otherwise it just tries and tries and tries to reconnect,
draining the battery like crazy, and sometimes resulting in these
mysterious reboots others are experiencing as well.
is this the phone or a network problem? (tmobile in the netherlands)
i was on the same network, same SIM with an older LG android phone
and i dont recall having this problem, so i am a bit hesitant
to blame the network for every outage...
should i just send it back for repairs/replacement?
system version: 45.0.74.MB526.Retail.en.DE
baseband: EPU93_U_00.60.00
for a while i will keep the phone in 3G mode to see if the same
problem exists. as my mobile data needs are low, it would be
a shame if i cannot keep it in GSM mode because of this...
I had the same problem couple of months back but since I'm on msginger don't have that enjoying problem anymore.
Ohh and as far as remember it was only when the battery was on maximum save, now I'm using custom and it's fine

i am on custom saving mode. i think that the saving modes, where
the data connection is cut off after some inactivity, just flesh out
the problem more, as trying to connect back to the data network
happens more often then during normal use, when data connection
is kept alive all the time.
since i set the connection mode to 3G or better, i did not have the problem
but that was only a couple of hours ago. sometimes a day goes by
without manifesting itself...
I'm on 2G all the time. And the custom saving still got set up for cutting the data off but i don't seem to have that problem anymore i can check later on if it would still appear on max saving.
Sent from my MB525 using XDA Premium App
so after days, it seems like i cannot reproduce these problems
while on 3G. seems like 2G only for data is not 100% reliable
either because of the phone or the network itself, or both.
pitty.
i m having problems with network reception with the 7.2 CM rom on the defy+.tried the baseband switcher in this link but still little or no reception
http://forum.xda-developers.com/showthread.php?t=1203297
i have been on 3G last couple of days, and no data woes.
however i had a spontaneous reboot, so the reboot problem
is seemingly not only a 2G issue (if it is)..

[Q] Loosing Data Service

This is my 3rd Sprint S4 over the past few months. All of the devices are loosing the 3g icon but will show bars. Voice and text works fine, data and 4g does not, i have noticed it usually happens when i leave a WiFi area and it has trouble switching back over to cell data. I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?
This happens to me as well. Just Sprint being crappy. Try turning airplane mode on and off, same effect as a reboot but faster.
I tried the airplane mode toggle but didnt seem to fix it. If i use even the "Hot reboot" option in triforce rom that doesnt fix it either.
Assuming this this is the same issue I always experience, there is no fix. It's a network thing. Is there 4G in your area?
What happens to me is my phone will be on 3G, then start receiving 4G, but it doesn't recognize that the data service is now different, so nothing works for 15+ minutes or until I toggle airplane mode on/off.
I take it you've tried just turning WiFi off?
Haha, yea, welcome to Sprint. Enjoy losing data when it's least convenient (such as when you need to use navigation or missed your exit and need to be rerouted). Oh well, the price we pay for unlimited data, right?
I have noticed the same thing since I activated my LTE radio. LTE is expanding in my area so I constantly go in and out of 3G and LTE service. Sometimes when this happens data just ****ing stops working until I enter airplane mode and then come back out of it (a reset works as well). For some reason (or it is just a coincidence) The problem has amplified since installing 4.3. Has anyone else noticed an increase in this problem since upgrading? This is absolutely a Sprint problem? Do we know that people have this same issue with other Sprint phones?
I have the same problem. From wifi to f data takes a little bit of time for it to switch over especially since the data toggle is gone with the 4.3 update. Unlimited plan is water downed from my experience compared to tmoblie. But tmoblie service was horrible.

Well Sprint's speed has always been an issue for most of us. That is no surprise. I at least expect to to work AT ALL which apparently it is incapable of doing recently.

If wifi is on 3g/4g is not there,, turn off wifi and you should see icon,, if you see bars it's most likely working :sly:
Edit just re read your post, I have the same issues sometimes and as posted above toggling on and off typical works for me,, good luck
Also is your network set to
CDMA/LTE/EVDO? Just throwing out ideas

I get this issue all the time & I have to do a battery pull to get my phone working again. Anyone flash a new modem which fixes this? The SGS4 is 10x worse than my HTC EVO 3D was with this issue.

Seems like a hardware problem based on your description. I am fully convinced that this whole flashing modems things is just a feel-good measure for people who have exhausted all other options. It was big in the Galaxy S2 days, but I have never seen any measurable difference between modems in any meaningful metric on that device. At least not one that could not be attributed to other factors such as signal quality and network load, and nothing consistent. A different modem isn't going to fix a hardware fault or magically improve Sprint's awful service.
