I have had a wizard for about a month now with few issues. After the first couple days I settled on Jaguar 4.0 ROM, and it has been working great except for a few times when it freezes / won't let me unlock the screen to use it.
However, the past few days a big issue has come about. I can make calls easily, but I cannot receive them. People say it goes straight to my voicemail. My phone doesn't ring, doesn't tell me I have missed calls, doesn't tell me I have voicemail.
Last night I found one thing that may be part of the problem. On the top, it shows the network strength - this is always strong. To the left of that, it SHOULD show an 'E' symbol, possibly for the edge network (at&t) ? Anyways, I know the E is there when it works. I can also connect to internet via GPRS when this is there. Lately, that E symbol no longer shows up. Intead, it has a different symbol with an 'x' on it (two arrows in opposite directions with a small x). At first I thought this just meant I wasn't connected to the internet for data usage at that time, but I've learned that I cannot receive calls either. If I try to connect to the internet, it says connecting but never connects.
If I click around in the menus and connection menus, or reset the phone (sometimes), eventually I can get the 'E' to show again and the phone is working like it should (not sure how to actually get it back, but after clicking around in menus I can). However, it doesn't stay. It seems to stay on a few minutes, I think everything is ok, and then I look at my phone 30 minutes later and that symbol is gone, thus I am no longer receiving calls.
It's weird, because I can make calls easily regardless of the symbol there. I'm clearly connected to the network, have a signal, etc. I've checked flight mode, which is always off. I've checked settings and everything looks ok.
Any ideas on what is going on or how to fix this?
Edit: Note - Turning flight mode ON and then OFF seems to get the E back and the connection restored properly. I think the same happens by turning the phone OFF then ON. However, it only stays fixed temporarily (less than 30 minutes) and gives no notice the proper connection is lost. I just find out next time I look at the phone and see it's not working and find out I've missed important phone calls.
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.
Hello,
I have the Sony Z2 on Tmobile USA, completely stock (no ROMs, or modifications).
Approximately twice a day, my Z2 randomly stops receiving calls, making calls, and accessing the mobile internet. It still shows plenty of "bars" on the reception meter, thus I have no idea that I'm not receiving calls.
When it happens, this can only be resolved with a restart, or turning on Airplane Mode, then turning it off again. The problem will usually come back within 6 hours, requiring another restart cycle.
If I have WiFi enabled when this is occurring, then I can still access the internet via WiFi, but I will not get calls and text messages. I get no indication anything is wrong, until I try to place a call and it fails.
When this happens, the "Signal Strength" meter (under "About Phone", "Status") does not change, it would read something like -95 dBm no matter where I would take the phone (even in areas of poor coverage). It appears the phone simply looses synchronization with the mobile network, but doesn't notify the user. Other phones on the same mobile carrier continue to work perfectly at the same place, so it's not a mobile carrier issue.
I've had this phone for 8 months, and this is a new phenomenon.
This is Z2 model D6503 and I am on the latest firmware (Android 4.4.4, build 23.0.1.A.0.167). Sony support said "reset the entire phone", of course.
Please share any thoughts you may have about what could be wrong.
Any input is very much appreciated. Thank you!

Most probably random software issue. If you installed any apps recently one of them could be the culprit. Uninstall them or trying booting into safe mode and see if the problem persists with continued usage.
As a last resort you can factory reset the device using the PC companion. But since the lollipop update is round the corner wait for it and see if the update fixes the bug.
If a factory rest or firmware flash doesn't solve the problem its a hardware fault, return it and ask for replacement.
I know I randomly get data drops, but I always cycle mobile data off and on to fix it. Next time it happens, I'll try to make a call to see if this is the same bug that I've having.
Quick update:
Right before the problem started, I installed the current-as-of February 2015 version of Audible on my phone.
After I uninstalled Audible, the issue appears to have disappeared (haven't seen it re-occur yet). Bizarre, but that's the situation,
I have an SGH-I337M on the Bell network. After a flight, I took the phone off of airplane mode and it did not regain service. After a restart service reconnected (data and texting) but then disappeared after a minute. Generally, I do not get "No Service" errors and I have never gotten "SIM Card Removed", the bars and LTE in the corner persist although nothing seems to come through. I did some searching and found this thread:
http://forum.xda-developers.com/galaxy-s4-att/help/service-problem-i337mvlufni2-t2977997
and gave the instructions a shot. I was able to use data and text for about 5 minutes initially, but since the first boot it has reverted to the original problem (coincidence?). I also took the phone in to a repair shop and had the SIM tray replaced, which did not solve the problem either. I have tried using ODIN to return to stock (I337MVLUFNI2_I337MOYAFNI2_BMC) and have tried CM11 and unofficial lollipop releases. The issue is identical in all cases.
I'm really hoping I missed something obvious here.
Thoughts?

Tested my SIM in another phone and it worked perfectly. Tested different SIM in this phone, same issues.
Bump.
The same issue here. The service/network is lost a few minutes after reboot. When I reboot my phone everything works perfectly fine - call, sms, switching to airplane mode, navigating through Mobile Networks menu items (in Settings->Connections->More Networks->Mobile Networks). After 5 minutes all those features/apps stop working. Everything looks normal but when I start one of those apps, the app hangs/freezes and stays frozen. For example when I try to place a call, the app is stuck in 'Dialing....' process and stays like that forever. When I try to end the call the app is not responding. The same thing with all apps that need/use network. All those apps stay frozen when started. Notification bar is showing I am connected to the network and network icon is showing strong signal. I tried different roms including stock rom but that didn't help. Looks like a software issue but I could be wrong.
Any suggestions anyone?

Is this a signal issue? I had MMS issues from before. I decided to do a factory data reset. Then this signal/wifi combo on the top right showed up in the photo listed on imgur. Or is this a bug? My wifi has been bad recently to add to it. No download booster or dev settings for aggressive handoff either. Any help is appreciated, thanks.
I noticed this on the first day I had my device (Wifi and LTE active at same time). Thereafter it went away. It may be that, on initial boot (or after factory reset), phone is communicating with network to send device info and status (IMEI, etc) to TMo. Once that's done, the simultaneous icons stop. Just a theory.
It comes and goes for me. I did two resets because of a phone dialer issue after using package disable pro.
you might want to chill on that PDP for now, until you get things sorted.
I've also seen the LTE icon pop-up on occasion while on WiFi. It seems to happen when the phone has been sitting awhile and I turn the screen on.
