Several times recently (I'm not sure whether it started after I installed the OTA update or if it happened once before then) I have noticed that my phone says "No service" and doesn't pick up T-Mobile again until I power cycle.
It's not that unusual for me to see 0 bars of signal strength in my house; there are dropouts at various places, and I saw the same thing with AT&T on previous phones, so it's not a T-Mobile or Nexus One issue. The problem is that, once every few days, I will pull out my phone and see 0 bars and "No service" instead of "T-Mobile," and nothing short of a power cycle reestablishes the connection. I've tried going into and out of Airplane mode, with no effect, and I also tried using Settings -> Wireless & networks -> Mobile networks -> Network operators, and it never found any.
Maybe related is that when I try to power cycle after this occurs I have trouble doing so -- a few seconds into the shutdown sequence the circling arrow stops moving, I get some sort of notification "ping" and the trackball lights up, and the phone just sits there for a long time. Eventually it reboots -- whether because whatever it's waiting for times out and it continues the shutdown sequence or whether it's responding to my frustrated poking at various buttons while it's sitting there apparently doing nothing, I don't know.
If it's a hardware issue, it's very intermittent; I always have service after the reboot, and as I said, this only happens once every few days. I'm inclined to think it's a software or configuration problem (I'm using the stock 2.1-update1 firmware). Any thoughts or suggestions? TIA.
It happened again this evening when I had some more time to play around with it, so I have a bit more information about this problem.
When I tried Settings -> Wireless & networks -> Mobile networks -> Network operators, the circular arrow spun for a minute or two and eventually a little pop-up appeared saying, "Error searching for networks" or something like that.
It occurred to me that the SIM card might be bad or have a bad connection, so I installed an app (using wifi -- which, BTW, I had on throughout this whole process) that allows you to copy your contacts onto the SIM card and ran it. That seems not to be the problem, though, since that app could access the SIM card just fine, while I still had no service.
I toggled Airplane mode on and off, but there was still no change. I then again searched for network operators; the circular arrow appeared and stopped, then a couple of seconds later the phone spontaneously rebooted and I have service again.
Anybody have any guesses as to what these symptoms might indicate?
Every so often i got service but I cna't send text messges unless I power cycle. If I try to airplane mode cycle it won't let me get out of the mode.
wow, a bit refreshing knowing that I'm not the only one with this issue.
I'm on T-mobile and within the last week I've had 2 occassions where I looked at my phone and noticed no service, a power cycle caused it to freeze on "powering off" screen and I would have to pull the battery. After it booted it I had full bars again.
Within the last 2 weeks I have had issues where I would not be able to send a text messages until i power cycled.
The last time I had no service was 4 hours ago. I had to pull the battery to power cycle and get service again.
Thanks for the reply. I, also, pulled the battery the first time it hung in the shutdown sequence, but as I said in my first message, since then I have managed to complete the power-down after the hang, either because whatever it was waiting for eventually timed out or because something I did (e.g., holding down the power button for several seconds) overrode the wait. Next time it happens I'll try just waiting to see if it will complete the shutdown on its own.
Just out of curiosity, did you have wifi enabled at the time this happened? Bluetooth? I'm not sure whether it's relevant, but I leave both on all the time.
As for the text message problem, I don't send a lot of texts, so I probably wouldn't have noticed if I were having that problem and can't comment on any correlation.
Oh, and a couple more questions: do you have NetCounter installed? And are you in a location where you sometimes or frequently get 0 bars of signal strength?

I have had similar issues with other phones...
For me it turned out to be an issue with my sim card.

I usually have both bluetooth and Wifi enabled all the time...
Dont have netcounter installed.
Dunno about the SIM card issue, unless its a combo of the N1 and my SIM card, because I swap to using my BB 8900 once in a while and I never have text message or no service issues.
Im experiencing the same problem, I have dropped calls in some spots around town (when changing towers it seems), I drop service when inside my home and cant send texts (until a power cycle), horrible 3G speeds of less than 1MB/S all around town (driving and standing directly under the Tmobile Tower that across the street from the tmobile store).
NONE of this happened with my G1....my 3G speeds always sucked though but were usually around 1.5-2.1MB/S.
Im located in Fredericksburg,VA.
(MY PHONE IS NOT ROOTED AND IS RUNNING THE OTA UPDATE1)
Im pretty sure it was the radio update, cause after i get out of a place where i get no signal at all, and i get to a open place I have to reboot the phone to get signal again
I've been busy for the last six weeks or so and haven't been following N1 news around the net. Has anyone heard of any progress on this issue? It seemed to go away on my phone for a couple of weeks, but it's back with a vengeance: it's happened to me about once a day for the last few days, which is more frequently than any time since I've had the phone, so I'd really like to get this fixed somehow.
Can you take a youtube video of it? the more the better to get Google to fix it.
Also these issues seem to be related over here too http://www.google.com/support/forum/p/android/thread?fid=1cc152dbb797df2f000483d7c88e343e&hl=en

Thanks for the link. It seems to me that several different problems are collected together there; mine is specifically the one where I go to zero bars (which happens fairly often; I have several dead spots in my house) and it never comes back.
A video of this would be pretty boring to watch; there's really nothing to see. The signal strength shows zero bars with an "x" and the home screen shows "no service." Trying to power off, or going into and out of airplane mode, shows the spinning arrow for a few seconds, then it stops; a few seconds later the screen goes blank; then a half-minute after that the multicolored "X" appears and the phone reboots itself.
No SMS Gateway
I think this is a separate issue for the phone not switching back to a connected state with the service provider. In the case of SMS, I have also noticed that you may have signal but you have no SMS gateway. No idea where it goes or why it does that.
For whatever reason you loose the SMS gateway phone number settings and become unable to send text messages without a reboot. This is evident by visiting:
Phone
dial *#*#4636#*#* (if you happen to mis-dial this start over after clearing the display or it won't work)
Phone information
Under SMSC: press Refresh.
If no number displays (in my case +12063130004) then you have no route for the SMS messages to take. Entering that number and pressing update will fix it but just restart so it can pick it back up from the SIM/Carrier configutation.

I have this issue sometime in a supermarket here, if I'm in it shopping for a while I loose all signal and have to reboot, also happened with my MyTouch jut didn't have to reboot the phone, but if I'm in there for a quick purchase, it works OK
@wmm, I'm seeing exactly the same issue (zero bars + reboots) and found another guy on the cyanogenmod forum with that problem. Maybe you can add your last_kmsg to this thread, even though you're on stock. http://forum.cyanogenmod.com/index.php?/topic/1599-loss-of-signal-no-reacquisition-issue/

Yep, that certainly sounds identical to my experience. Next time I have the problem I'll force a crash by toggling airplane mode instead of trying to power off (it seemed from the thread that last_kmsg would not be saved if there is a normal reboot, and indeed I have no last_kmsg from the reboot that resulted from trying to power cycle after the last time I had the problem).
Thanks for the cross-reference.

That would be nice, but I haven't seen any activity on the issue on the Android developers' board. Speaking as a programmer, these intermittent, once-every-few-days kinds of problems are a real pain to debug, so I can't blame people for not wanting to tackle the issue...
I had this issue but fixed it by installing the Radio Rom and OS again from the last update. Has not done it again. Now its a power button issue lol.
Hi,
I bought a Samsung Galaxy S about a month ago, and have been having odd problems with it since the off. Has anyone else had these sort of symptoms:
1. I occasionally lose my data connection - the icon disappears from the top of the screen and whilst I can still make and recieve calls and text messages, I cannot download anything in any app. The only way I've found to get my data connection back is to reset the phone. This happens maybe a couple of times a week.
2. My WiFi seems to suffer from a similar problem. I can be browsing the web on Wifi, then suddenly I'll not be able to download anything anymore. The wifi icon is still visible, but I'll basically be unable to download anything until I switch the wifi off and back on again. Then, it starts working as normal again.
In both these above scenarios, I think I've narrowed it down to primarily happening after I use the Android Market, but it's difficult to tell as it's very intermittent.
3. A couple of times since getting the phone, I've been unable to make or receive any calls. Even switching the phone off and back on didn't help - my signal bar was showing I had a signal and my data connection was still active. Couldn't tell if this was a network problem or not though as there weren't any people nearby on the same network as me. After a while, it started working normally again.
4. The email client randomly lost all of my email settings. One day I was receiving all my emails, the next day I had no email accounts set up at all.
5. I installed Sensor Dump and Phone Explorer to see what data was coming in from the sensors, and have noticed that the light sensor never sends any data. Is this normal?
I also have the usual slow-down issues, etc, but the above have got me stumped as I can't find anyone else reporting the same issues. When I first got the phone, I went crazy installing a load of Android apps, so initially I blamed the software I'd installed. After a reset and being a bit more selective with the apps I install and use, I'm still getting the same issues. I just can't pin down whether this is a faulty phone that I should return, or if there are software issues either relating to the way I'm using the phone or just with bugs in the firmware.
Has anyone else had anything like the above happen with their Galaxy S?
Thanks,
Chris.
I've experienced no.2 several times, wifi just stopping all data traffic. Not found out what causes it though.
As for the other problems, I haven't experienced any of those. Do you use automatic brightness on the display? If not, problem no. 5 might be caused by the sensor being turned off.
thanks for the reply - at least I'm not completely alone!
I have the automatic brightness turned on - which is why it seems odd. To be honest, I've never actually see the auto brightness do anything. It always seems to be the same brightness to me.
Cheers,
Chris.
Strange Problem
Hi,
I've experienced no.4 some times. My inbox did not show some older mails.

I think it might be normal that older mails disappear from the inbox after some time? My problem was that everything went. I had three email accounts set up, all downloading emails every hour. Then, one day I went into the email app and there were no accounts at all! I had to set it all up from scratch again.
I hear there are better email apps available for Android, so I'll probably switch to one of those soon.

and it seems that after my sgs lost its connection, it won't tell me, my msntalk just displaying the entire contact list just as it is. and i need to turn airplane mode on off to return it back
anyone have the solution for this?
Hi,
I bought a Galaxy S on Orange UK in July. I'm having the same problem as 1. quite consistenly now.
I thought it might be related to the green power battery saver app I had installed, but i've removed this and still having the problem.
I'm using the phone in several central London locations so I think it's unlikely to be a problem with the data network.
Any suggestion would be welcome since I'm often without data.
Thanks
Nik
ive 1 and 3 but very rarely so far
rebooting fixes it for me
running froyo jp3
for email i use K9, it's almost the same as the integrated mail, only much better (PUSH imap)

I'm actually getting this happen a lot now. It seems to be getting worse, which makes me think it might be a hardware fault. I generally lose my data connection once or twice a day minimum, but some days the phone is virtually unusable.
I have found that it's more likely to happen after using Wi-Fi, so my other thought is that when coming out of Wireless mode, the phone may not switch the normal 3G/HSDPA data connection back on. Most of the time I can fix this by putting the phone into flight mode and then back out, but sometimes it needs a complete reset.
The other problem I've noted with the data connection is that sometimes it seems to rapidly switch between HSDPA and 3G - the data icon at the top of the screen keeps going from '3G' to 'H' then back again. I guess it has something to do with signal quality but it only seems to happen when the phone is showing a good signal strength (four bars). The problem I've found when this happens is that it virtually locks up any ongoing data transfers, making it impossible to download a webpage or check my emails. Strangely the only way I've really found to stop this happening is to move somewhere where my signal strength is weaker, such as indoors, which then seems to make the phone stop attempting to use HSDPA. I can't find a way to switch off HSDPA from within the phone's settings while leaving 3G on.
I really am now finding that using this phone is an increasingly frustrating experience. I've found even more weird faults, such as sometimes my text conversations show the wrong people's names up against them, and then my replies go to the wrong people. It's like an insane, shiny mess of a phone!

I am indeed experiencing same problems above..it just drive me crazy with a need of complete reset everyday..
turning on n off flight mode won't change anything..
I really hope someone can bring a miracle to solve this problem..
I'm on XXJPC
setting the APN parameter(Setting-->Wireless and network-->Mobile Networks-->Access Point Names-->New APN) to 2G only seems to solve the 'lost data connection' problem..
I am connected 24/7 now..
Give a try guys!
I've had my Xoom since the beginning of March and this is the first time I've had this issue.
Earlier today my 3G wasn't working. I go to my settings and try to turn off the mobile network and then turn it back on. That didn't work, so I restarted the tablet. Connects to 3G no problem.
I come back from lunch and the same thing happens. I go to the settings and try to turn off and back on the mobile network. No dice. Reboot, 3G is back.
What gives? Anyone having this problem? Running 3.1 not rooted.
Well, this is an old thread - but I was doing my due diligence by searching before posting a question and this is the closest I could find. In fact, it exactly describes my recent troubles. I had to power cycle my Xoom 4 times yesterday to restore data. Turning data off and back on didn't restore data. Only a power cycle resolves it, for a while...
I live in a 3G only area. I just got my Xoom back from Moto service, after it got stuck in the Honeycomb boot screen animation for the 4th time in 6 months. Since getting it back, I've had these data connection issues. It's strictly stock OS, by the way. Android version 3.2.6 and build HLK75H
If it did it daily, I'd say it's a tablet issue. But yesterday was full of reboots and today it's been fine all day. Sound like a known issue or perhaps just a Verizon data problem?
thanks all!
Well I had something similar but reboots didn't fix it. Sent mine in for the LTE upgrade and returned with signals barely 50% and not staying connected, in either LTE/cdma or cdma modes. I took mine to work and inspected under a scope and saw cold solder joints on all the antenna connectors for the center pin. Reflowed them all and signal strength back up and not dropping data. Not sure if this would apply to you.
Thanks, Tiger. I think my Xoom issue is different since, when I DO have data connection, the signal strength is fine. And reboots restore my connection.
I have discovered that I can force this to happen by leaving an area with wifi coverage. My Xoom now consistently won't transfer from wifi to 3G. As an experiment, I turned off wifi today and it's been fine all day - running only 3G. But, if I have wifi on the transition from wifi to mobile seems to choke it.
data issues too
Mine used to be just fine. After the 4g upgrade I am now having these same disconnect issues as well. Should have never let it out of my hands... I am thinking it is time to root and rom and hope it is a software issue.

Well what your describing sounds more like an app causing the problem. One of ur apps is holding onto the radio (wifi or cell) and is not letting go so the tab can switch properly. Since you sent it in for repair I would assume you made backup before it went in and you just restored it all. Which if the cause is not an app, then one of the system apps restored data conflicts with what's in there now.
If you used titanium backup I would perform a full back up, wipe your tab back to default state. At this point just give your tab a dry run (just skip sign in and adding accounts so google doesnt restore your apps) and use wifi/cell, browse web, for while to see if problem continues. If not then restore "missing apps and data". Not full restore. This way it only restores what's missing (which of course won't be the system apps/data). After this then things I would only restore in system apps would be browser favorites.
I need help this is driving me insane!
I've been running Dynamic Kat Rom for about 6 months or so now. Everything was working fine then all of a sudden a week or two ago I noticed my mobile data is not enabling at all.
I can only connect on Wifi and only receive SMS.
I've tried
- Messing will all the data/network settings
- Turning Mobile Data on and off -- no effect
- Toggling Airplane Mode on and off as suggested in some places
- Wiping everything but Data and reflashing latest ROM
- Reseating the SIM card
- several other things I forgot..
I do see the carrier information in the top left (AT&T) and I am getting signal bars.. but not indicator for 4G/LTE/etc
I've been messing with this for a week now and it's driving me insane.. I can't get a connection anywhere unless I'm on Wifi.
Anyone have any suggestions? I'm not super phone savvy, but willing to try any suggestions anyone may have.
Hmmm.. weird.
So I called AT&T and asked them about it.. figuring it could possibly be a carrier issue.
They told me to try things I had already done 100 times.. turn the phone off and on.. turn wifi off... etc.
I turned Wifi off... (which I had done 50,000 times before) and 4G popped up.
I guess they did something. So.. guess it's resolved.
Problem has returned.. same issue. I will have 4G signal for hours and then all of a sudden it will drop completely and I can't get a data signal no matter what I do.
I see AT&T in the corner and have signal bars, so I AM getting some kind of signal.. but no data connection whatsoever.
It seems completely random and intermittent.. I can have data signal for days with no issues then I will lose it for days.
Restarting the phone 5-20 times sometimes fixes it.. but that's about it. Anyone have any ideas what could be causing this?
Bad signal / carrier issue?
Call them and report a fault in your area?
I have called them multiple times, they will reset the signal.. sometimes it will come back right away, sometimes it wont.
And this happens regardless of where I am. I know for a fact where I am right now has a great signal strength. I get 4-5 bars on average. But this also happens at home as well about 20 miles away, which also has a good signal, or anywhere I go really it can happen. This isn't in the middle of nowhere either, it's smack in the middle of SoCal (LA/OC)
I'm beginning to think it may be a SIM card issue or a hardware issue with the phone. I'm going to try asking them to send me a new SIM card.
Another thing I will notice is when I have a working 4G LTE connection, and I'm on Wifi... it will sometimes CONSTANTLY switch back and forth between wifi and 4G like every 10 seconds, even when I have full signal strength on Wifi and 4G.
Disable Smart Network Switching in WiFi settings
it's nothing but a buggy headache, disabling might fix most of your problems, almost certainly the constant switching back and forth
Yeah forgot to mention I have disabled that. It's disabled now. It solves the constant switching back and forth (when I actually have a data connection), but that's kind of a separate issue as the losing data connection.
Edit 5: Gonna go ahead and declared this solved, the problem hasn't come back since I factory reset and reflashed MHC19I (not Q) from scratch. No more issues with wifi not autoconnecting or taking excessively long to connect, no more battery drain (got nearly 48 hours this weekend including a good amount of time spent in a poor/oversaturated service area at the Grand Prix), etc. Probably going to wait until the May update before flashing any OTAs.
Edit 4: Two days later and still seems to be working fine. I'm seeing some other issues on the April update (significant battery drain, slow wifi connect, etc.), so this morning I tried rolling back first to January (wouldn't get LTE) and now to March (fine so far). With the exception of keeping my media, I'm setting this up completely new, i.e. redownloading everything from the Play Store, to avoid any weirdness from restoring backups.
Edit 3: A factory reset done via TWRP (which retained my media) seems to have solved it for now. At any rate it's been acting normal longer than anything I've done before. This includes restoring my apps + their data via TitaniumBackup (but not system backups), reflashing SuperSU and otherwise getting my phone back to where it started. I've tested things that were known to cause it before like having wifi active but leaving my signal area and having it revert to cell data. The only issue I've noticed now is that wifi no longer seems to autoconnect when it's in range of my router. Not a huge deal but kind of annoying, if anyone has a fix for this I'd appreciate that too.
Edit 2: This issue is NOT resolved. The problem came back after working for a little while. Once the LTE fails the wifi will never reconnect on its own. It seems like everything still works except loading images from anything (reddit, instagram, etc.) and loading bookmarks. I can make google searches, download apps, go into reddit comments, go to instagram profiles I've never been to before, and so on. Is my device defective?
Edit: It appears that going through the motions of flashing the latest update (save for recovery.img and formatting userdata) has fixed the issue. This includes reverting to the stock kernel and flashing the vendor.img, which I hadn't done before. Wifi can be flipped off and on and will reconnect and there are no "!"s anywhere in sight. Strange considering I essentially went through the whole process minus the stock kernel and vendor.img, just out of order, with no effect.
Can anyone offer insight as to what piece of that process might have fixed this? It's not clear to me which pieces of the update are responsible for wifi and cellular connectivity besides the radio and kernel. Leaving the original post below in case anyone has anything to add or is going through this same issue. I'll update this post if the issue returns.
---
As of just this afternoon I'm suddenly getting a strange new issue that I can reproduce pretty consistently. I first noticed that my wifi signal was claiming to be connected but with no internet, and showed a little exclamation point next to it. I disabled wifi, and noticed the exclamation point jumped over to LTE. In both cases, I can still essentially use the connection. I disabled cellular data with wifi connected and could still browse the web, and likewise if I disabled wifi and the exclamation point was back on the LTE symbol. However, I notice some apps like Instagram will refresh posts but no longer load images, and reddit will load posts but not follow any links or load any images either.
Things I've tried:
-Flashed the 2.50 radio (down from 3.61)
-Flashed the MHC19Q system.img and cache.img
-Installed ElementalX kernel (at first it looked like it fixed the LTE issues, but really it just made the "!" go away; still seeing the same issues when I connect to wifi and then disconnect)
-Deleted and readded the nxtgenphone APN (I'm on AT&T)
-Tried to get into *#*#4636*#*#; I get "Connection problem or invalid MMI code."
-Cleared cache/dalvik in recovery (hey, you never know)
-Rebooted my router to make sure it's not an issue there; all other wireless devices on my router are fine
-Removed and reseated the SIM card
In all cases I can still send and receive texts and certain apps will continue to function about halfway, such as Instagram mentioned above. Switching airplane mode on and off doesn't help. Furthermore, once the wifi connection first gets the "!", it will no longer automatically reconnect as it doesn't find a working internet connection.
After an initial reboot it will appear to be fine; wifi connects automatically, no "!"s anywhere in sight, and everything seems to work. As soon as I disconnect from wifi, this issue starts. As mentioned, it will no longer reconnect to wifi and cellular data doesn't seem to work.
Anyone have any thoughts or suggestions as to what the issue may be? This started out of the blue this afternoon, I haven't made any changes to my phone since flashing the April image. My bootloader is unlocked and I'm rooted, and save for the ElementalX experiment (going to go back to the stock kernel) everything else is stock.
Any help is appreciated. If you need any more info, let me know.
Did your problem get resolved or did it come back. I'm having a number of problems on t-mobile since upgradingj to mhc19q

So far so good, the issue hasn't returned, although I'm really not liking the latest update. I'm considering rolling back (is that something I can do? I don't see why I couldn't) to January or so.
I'm still in limbo. T-mobile have been helpful but it's in Google Nexus support's hands and they have been less than responsive to say the least.
Next step is likely replacement device but in the mean time I just finished flashing 19i and will see if that has the same issues, then I'll try the previous build.
I'm kicking myself that I didn't check the version numbers I was on before applying April update. Ah well, lesson learned,

Out of curiosity are you doing a full wipe before flashing different builds? I noticed in my case the issue didn't go away until I did a factory reset, which I think suggests something was corrupt or otherwise affected in the system partition. Since doing a factory reset (and now after doing a couple more) the issue seems to have gone away and I'm no longer having wifi/LTE issues - well, except for not getting LTE at all on the January update, so now I'm back on MHC19i.
Current status: My issue appears to be with t-mobile band 12, the new band that t-mobile is rolling out now.
It appears that the phone "prefers" band 12 to the older bands (like 4).
Rolling back to an image before band 12 was added (eg MDB08K from October) gives me back reliable LTE on band 4.
Sent logs to t-mobile and Google and waiting.
