You know, I think I've had this issue with just about every single Android phone I have ever owned... in fact, yes - every one. The bars will go grey, and even if it indicates 3G, H, H+, whatever - it just won't reconnect to data without a reboot. Sometimes airplane mode will work, but often not. Many times when I leave a place that has no cell service, but has wifi, it'll lose the wifi but won't pick up the data connection without a reboot. It's hugely frustrating and I've seen it from my Nexus One to my Vibrant to my Nexus S to my Sensation to my Galaxy Nexus to the GSIII now. I figured it was T-Mobile or an Android bug of some kind in general.

Gotta say I agree. I have owned three (technically four if you count the lemon GNex I had before this GNex) android devices and experienced problems relating to losing data service/cell service (or some combination of) and having to do the Airplane Mode trick with each of them at various times. It's not like it happens every single day, but it's definitely often enough to realize it and have it irritate you. I'd say for me on my GNex it's once a week or so. It happened back on my Motorola Atrix original, as well. It has got to be an Android thing, not manufacturer-specific. My previous line of smartphones (Blackberries) on the same network (AT&T) never experienced this - ever. And I live and work in the same exact areas as I did during those days.

I'm glad someone else agrees.

I'm sad to report that this has not been fixed with the 4.2.1 update.

My nexus came with 4.1 JB and i have installed 4.2 takju manually. the phone was working perfect so far till recently, when all of a sudden, it no more connects to cellular network. The issue happened in the middle of mobile data roaming but however could not get resolved even after returning to home network.
My baseband is i9250XXLH1 and i am on Vodafone India network.
The network bar completely shows blank. While in open space like roads, it catches signal but in grey and no mobile network.
While manually selecting the network operator, it gets registered in open areas not inside the buildings.

Since GN is not officially available in India, there is no warranty anyway included. i did these on my own:

1. Factory reset: No use
2. Re-flash of 4.2 / 4.2.1 : No use
3. Reflash of radio and clearing cache: No use
4. Flash JB4.1: No use
5. Re-flash of 4.2/4.2.1 : No use
6. Trying out other SIMs and other operators: No use
7. With GetRIL app, it displays my current RIL/Baseband is matching
8. Tried changing the GSM/UMTS bands to Auto/US/Euro/Japan etc.: No use
9. Typical network signal strength of -95dBm and 9 asu

Can it still be a software issue or a hardware problem ?? Appreciate your help and views

Flashed 4.0 : No network signal
updated to 4.1: No network..
Even when signal catches in fully open areas, call quality not good..

What does that article have to do with data signal problems?

Most of the data loss issues reported in this thread have been attributed to random reboots experienced on phones running 4.2.

Random reboots is a separate issue and has been covered in separate threads. 2 bugs in same JB version.

The only time I ever experience any data loss is immediately and invariably following a random reboot–and others have said the same–so would it not therefore be safe to assume a fix for the reboots could also prevent said data loss issue?

Not really, no. I have had some data issues and never a reboot. I suspect it has more to do with the wifi disabled on sleep by default. It may be disabling more than just wifi on sleep. That is not to say the next update will not fix it without specifically addressing it though.

[Mellimel22]

I've only had ONE reboot since I've flashed 4.2 and I know why that time so no issues with 4.2.1

i never had a problem of reboot..even i used the handset on 4.2 for couple of weeks before this issue started..
I tried whatever i can from the advice from other forums, not much of help here in this forum it seems on my way to the service center

[Onkar Joshi]

HI,

I am also facing same issue. I am using Nexus 4 in Pune, INDIA.

No issues for me. You sure your provider isn't having an issue?

[pontiac005]

Sounds like a setting was switched.

Are you on Tmob?
I installed the 4.2.2 update last week, I believe. Today all kinds of data signal issues. H+,3G,edge and G, then nothing.

Called Tmob, he sent me to the store to get a new sim. New sim in, signal returned. BUT now its going through the same cycle over and over again.

I was getting speeds like 11mbps dl/3.4ul. And now I'm at 0.05dl/0.02ul.

Battery pulls, sim pulls don't help. Airplane toggle doesn't help. I don't want to factory reset, from what I'm reading that doesn't help either. I'm not rooted, don't want to do that.
I'm thinking about uninstalling the update, but that looks like it doesn't help either.

My bill is paid, lol. I'm on unlimited 4G, so it's not like I'm being throttled, which was my first thought. I have noticed that the notification vibration is really slow and dragged out since the update. Lol that may have nothing to do with anything. But I'm so frustrated at this point. I've never had a problem with my Gnex on Tmob. I read in another forum about them blocking imei's from unknown carriers? I knew I shouldn't have updated. I've never had a problem with the other updates. But reading how this one was blocking LTE, it just seemed like a bad idea to update. Again that may have nothing to do with it, I'm not very techy. I just want my phone working again

edit: it's been fixed. I called Google,lol. Then I called Tmob back.Spoke to a higher tech rep, she ran through the regular with me. I did notice on mine it said the mobile network state was suspended? Asked her about that. Told her I never had a problem like this, had the phone for awhile. She was going to make a ticket, and found out there are upgrades being done it my area. That makes me wonder because the first two techs said there was nothing going on. She said,because she was opening a ticket, she could see more of what was going on. SO as of now my data is back. No more switching, or completely losing its signal. That weird vibration is still there though. Call your provider and have them really dig to see if there are upgrades to towers going on. That was my first thought, until the first two told me no. I was ready to tear my phone up because of them.

[Medzz]

No issues for me. You sure your provider isn't having an issue?

Yeah I went to them there not having any problems with there system I tried everything nothing changed sigh

This is beyond frustrating. I switched from a galaxy S2 on t mobile to a galaxy nexus because I wanted pure google on my phone and I get to deal with this. With my GS2 I would get -91 dBm 3-4 bars of signal no problems at all. In the same place with my GNex since the 20th of last month I've had nothing but trouble. I lose all signal, I'm talking no cellular signal at all. I go to check my signal strength and it shows -113 dBm no signal bars on the phone at all. This is running 4.2.2 in north east Ohio on a UGLG1 radio and I'm talking it's so bad I can't send or receive texts or calls at all let alone use data. What makes it worse is I would randomly look at my phone and I would have 1 or 2 bars and soon as I touch the phone the signal would disappear

I've been digging around since 10pm it's 4:46AM right now and I think I found a fix for this you guys. You have to be rooted to do this but so far for the past few hours I have had no signal issues at all and my signal is -87dBm full bars and better then my GS2 ever was. The fix totally makes sense to me and if you have some android root and rom knowledge it probably will make sense to you also.

When the screen goes off the voltage supplied to the phone goes down, basically killing your signal in the process, when you turn the screen back on the voltage changes but for some reason the cell signal isn't changing like it is supposed to. Here is a link to the XDA fix that I found and that I am currently using and so help me god this is actually working for me

Make sure you do the test first to see if this is happening to you. It happened to me as soon as my screen went blank. If it happens to you like it does me then apply the fix. Everything you need to know is listed, there is a download link to the file that fixed my phone right in the post. Hopefully this helps you guys out and if it does please click my thanks button

Update on this. I am still getting excellent signal, have had no issues at all. This has been for about 18 hours now

No, grey bars means no data connection.

I have to enable/disable airplane mode all the time to start receiving email. I don't have this problem when I am using WiFi or touchdown!
