My MDA Vario's phone seemed to be dead because when I tried to call, it would just display 'dialing' for a bit and then disconenct (never connects or rings), and when I tried to call my number it went straight to voicemail, although the antenna indicator showed that I had a few bars of network. I soft reset and it's fine now. Any idea what may have caused it? I'd like to avoid this happening in the future as I have no way of knowing that it's like that unless I try calling and it doesn't work.
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.

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!
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'm on Rogers Canada and have their device.
Set up everything correctly by doing the setup and got an SMS notification that the wifi calling is active.
When I turn on wifi calling it says enabling for about 2 minutes and then it says enabled. However it doesn't actually work. I never get a wifi calling icon in status bar.
Called Rogers they said everything is good on their end.
Tired different wifi network and even a factory reset but no luck.
Any other suggestions?

Have you tried to test wifi calling? What kind of statusbar icon are you looking for? Just wondering whether it's really not working, or you are just not seeing it because the indication is subtle.
I was all ready to say "I have AT&T and enough dead spots at my house that I can verify it works well." But now that I am looking, I am seeing some strange behavior I have never noticed before.
First of all some terms / definitions. On the AT&T variant (Rogers might be different) you will get a special icon next to the "AT&T" in the notification bar, which is a little handset with a wifi icon, when you have an active wifi call. When you have wifi calling turned on, the normal wifi meter changes only slightly to one with a little + on it.
I had wifi off and toggled it on in order to see those icons so I could properly describe them here. I just had the normal wifi icon. I made a call, and it did not indicate it was using wifi calling. But after I hung up I had the wifi+ icon and the next call did indicate wifi calling. I repeated this process several times with the same result, even waiting 5-10 minutes to see if it became enabled on its own after some time. Now, since I always normally see the wifi+ icon anytime I happen to notice it, and I rarely make calls but frequently toggle wifi, there must be something else that triggers it. Sending a text seems to do it as well as a call. And a longer wait might do it also.
So, now that I have done some more thorough experimentation, it seems that there might be a little bug there. Or it might just be related to the particular wifi network I'm on right now.
Just tested it on my home wifi for comparison, and wifi calling came on as expected within a couple seconds of enabling wifi, which would probably explain why I never noticed this happening before.

Thank you for your reply.
According to Rogers I am supposed to get that WiFi icon that tells me WiFi calling is enabled but I never do. Sounds like I should have similar experience as you do.
I have a ticket open with them and we will see what they reply with next.
Even though I don't have the icon I tried a few things to make sure if it is working or not. One is turning on Airplane mode and enabling WiFi. Go into settings and it says WiFi calling is being enabled. This always takes about 2 minutes to turn on however calling never actually works. It's like something is blocking the WiFi connection but I've tried 4 different WiFi networks. It seems like you get that WiFi calling enabled right away after connecting to WiFI.
