GSM full bars greyed out with no connection - Samsung Galaxy Nexus

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.
I'm on 4.0.1 Google build anyone else get this issue?

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.

Been having same issues on Wifi and 3g, causes huge issues with push gmail
Edit: I removed dns changer from my phone, and seems to be helping

Thanks Menek, I am still on 4.0.1. Hopefully soon I will get an OTA update.

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?

SGH-T999 loses signal after ending a call

Hi all,
I recently discovered that my phone is not maintaining the network connection once I end a call. Whenever I end a call I can visibly watch the bars deplete. I set a numeric indicator for signal strength and I watch it go from -85 while on a call to -113. The bars at this point are completely gone and any calls made to my device go straight to voicemail.
One quirk is that I am able to reconnect, and maintain the connection with the network simply by triggering and subsequently disabling airplane mode. This of course only works until the next call has been completed, wherein the signal strength dies again.
I should mention I am running cm9 which was flashed using cmw. I've heard about the same thing happening with stock nexus devices, but was curious if anyone else has had similar experiences?
Thanks for any and all insights,
Well now this is a little strange, but I've found a way to stop the signal from being lost. All I have to do is restrict my device to 2g networks. This would normally be unacceptable, but I don't actually have a data plan as I'm a wifi only guy.
My imei was wiped when I flashed cwm using Odin, so I wonder if this may have something to do with the issue. Maybe others with borked imeis experience something similar...
I'd still like to see what others may think on the matter despite the work around.

[Q] Signal Issue?

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?

[CM10] loosing data connection until reboot

Hi,
Usually i have wifi enabled permanently, as i have coverage at home, university and t-mobile hotspots. But my nexus sometimes does not get a working data connection if i disable wifi or come back from flight mode. Icon shows reception and 3G/H/H+ but stays grey. I can't access any internet services like mail,http...
If i reboot the device, everything is fine.
Any ideas ?
Latest (-3days behind max) CM10 with stock kernel, XXLF1 baseband, tmobile germany
P.s.: tried to search with google, found nothing. Currently the nexus is my only internet-capable device, so i am sorry if repost...

Try toggling airplane mode?
Beamed from my Grouper.
Same issue here. Get random signal losses and afterwards no data until reboot. I've experienced this with other Roms as well. Toggling the airplane mode sometimes help for data recovering.
Try setting your minimum CPU above 500 Mhz...
How can that change the signal issues?
Maybe toggling wifi helps (sometimes)

I have exactly the same problem on galaxy s. The status bar shows mobile network connection, but the symbol stays grey, and connection is not there. Reboot is the only safe way to solve that. Sometimes toggling airplane mode helps, last time toggling wifi helped.
Changing APN seems to be helpful. Someone that looks good with the current provider.
almost same issue for me...
but there is some weird difference...
I have a GSM Galaxy Nexus latest radio, consistent RIL and latest CM10.
I lost data suddenly while browsing.
I can see blue signal with 3G, start browse and it change to H/H+. No problem until now but, when data returns to 3G, all further requests stay "pending" for a while (phone call is not working in this state!!!!). after a minute.... CRASH, all signal lost. Something like a reset.
even toggling data does not work... I simply have to wait that the phone decides to work again.
I'm from Italy, carrier is Vodafone. Someone with some hint?
thanks!

Because on earlier builds of some AOSP ROMs, the radio had a tendency to go to sleep and not wake up when the frequency dropped too low. The common fix at the time was to use a higher number for the minimum frequency...
Read you must...
I was looking up the answers to this same problem. When I'm staying still my internet is fine but when I'm driving down the road I lose signal. I did a google search for "cm10 losing data connection". This is a "normal problem" it is caused from changing between 3g and LTE 4g. I'm still looking up solutions to this problem.

Radios Dropping

Anyone have an issue with their phone randomly dropping Wifi/Cell connections? Sometimes it doesn't happen for a day or two sometimes it happens 3 times in 5 minutes.
Starting to think my phone is defective...

I've tried that and it's still dropping... Would PRL/Profile also effect my Wifi connection? All data connections drop.

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.
Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.
Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.

The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!
hmm maybe mobile settings?
Ive found LTE/CDMA setting to be not so good.
Its providing me eHRPD signal which is stop and go web browsing is murder.
CDMA only setting is providing Rev A signal fast web browsing
Sigh, so it seems as if you guys are losing wifi/3g....is it affecting voice radios or LOS/dropped calls?

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.

Network loss

Ok guys, having a real problem here. Often when I am connected to either 3g or wifi my phone will stop picking up signal suddenly. AIt's almost every time and I will have to disconnect from the network manually and reconnect and it will instantly pick up signal again for a while then it'll repeat. When it suddenly stops it doesn't show on the status bar that I have lost any signal. With 3g its kinda just at a stand still not receiving or uploading and with wifi it just stays the same but I'm still not picking up a signal because by web pages won't load neither will other apps that require network load until I manully disconnect and reconnect. Is anyone else having a problem like this? I don't think it was like this when I firs got my phone a month ago. I'm at a loss. Any help is much appreciated. Oh I'm completely stock btw haven't rooted........(yet) lol

It has happened to me a couple times that I have noticed. I will be streaming music and walking and all of a sudden, nothing.
Even a soft reboot does not help. It will require a full reboot generally to solve the issue. I have not been able to identify the issue specifically. I suspect it might be related to LTE testing in my area.
What's the LTE status in your area?
No lte yet but as I stated earlier it happens on wifi too. It'll still show that the signal is connected but my pages want load at all after it happens and when I try to refresh it'll say that the webpage could not load because there is no network. Only until I manually shut off 3g or wifi in the settings and turn it back on will it pick up signal again but only for about 5 minutes. This has happened in various locations on 3g and wifi and will even happen at home wifi.

I've had this problem too. Sprint replaced my phone and it never happened again.
I think reactivating hands free actually fixed my problem...for now anyway. It's not losing network like it was before. All I did was enter on the phone dial pad ##72786# that'll reactivate. Hope this helps
