So my girlfriend's Nexus S has been losing the entire voice and data network and going into no service mode, no biggie at first, just cycle airplane mode, then it went on to rebooting because you would select airplane mode from the power off menu but it would not check the box in the wireless settings menu.
After the reboot the box would show checked and airplane mode could be disabled and the service would resume. The the phone started getting stuck in airplane mode and not even rebooting it would bring it out the first few times, then it got to the point of resetting the phone, a wipe cache/data reset didn't fixed it. So off to T-Mobile for a new sim card. Rebooted the network immediately. And as of last night its back in full force and now not even a new sim will resurrect the network.
Have tried wiping, reflashing stock 2.3.3, new sim again, multiple resets, had to get an toggle widget to get it out of airplane mode and still a dead network, all this time the network in the *#*#4636#*#* menu showing unknown and is not able to be changed and reverts back to unknown immediately, OEM specifics settings button is greyed out and you are not able to disable the radio either.
While I'm going to call Samsung on Monday and I guess send the phone off, I worry about mine because it too does it but only once a month or so, but I do constantly have issues resurrecting the phone from airplane mode at times because the box will not be checked in the wireless settings menu but I can see the airplane instead of network bars, problem persists with reboots sometimes.
I also would like to add that even when the box is not checked in the wireless settings menu for airplane mode, if you click it it just hangs forever and will try to select but never will and stays grey like its turning everything off, but if the scren goes off its like you never tried.
Has anyone else seen this? I have seen a lot of people with data network issues or having to reboot to get voice network back but nothing as bad as I'm experiencing.
Both our phones are and have been completely stock and unmodified.
Thankfully we still have her Vibrant and in case I need to send mine in my Nexus One.

Have you tried restoring from another persons' pre-made nandroid backup?
This over-writes the radio firmware, you should give it a go!
I also found that I had problems on 2.3.3, however reverting to 2.3.2 gave me no problems!
Just contact me if you need any help restoring from a nandroid backup or finding the 2.3.2 backup files

Is that true? I am just on the verge of calling samsung. My phone won't connect to or display any available networks, and is pretty much now dumbed down to a small tablet. I've tried everything except another persons nandroid backup. I've been told to stay away from flashing another persons... but I'm really desperate.
If you could provide me with a backup, that would be awesome.
I'm having identical problem.
It was working fine yesterday, look back to it and now it's got no mobile network, nothing. Just the no bars and cross symbol. I've tried wiping dalvik cache, reflashing the radio, wiping data/factory reset, reflashing the rom, restoring with a backup (Backup of when I first rooted the phone) and still no signal. Nothing has worked..
Anyone got ideas on how to fix this issue?

Can you search for and view available networks?
This sounds like the CM7 powerwidget problem (3g/2g) I used it and I loss all network, phone process will crash every second, however if your phones are stock I can't think in anything causing it.
For CM7 you'll have to reflash and delete userdata or edit the sql database for the providers and change a value to 0, but you need root.
When I went to *#*4636.... my preferred service was "unknown" too, but now it is OK.
Try to dail:
*#*#4636#*#*
and find your network information.

Nope. Sits their 'searching' but nothing shows up.
In, *#*#4636#*#*, it gives little to no information. Just says nothing for current network and for GSM disconnects it has,
Sate: DvInactiveState
disconnected with last try
at 9:59AM
fail because No Error
And that time never changes, stays at 9:59AM.
As my above post suggested, I've tried doing a factory reset and reflashing. I don't think I use CM.. I flashed with Oxygen 2.1.6 (using it's kernel) but I restored to Oxygen rom and trinity kernel after it didn't work.

That is the EXACT same problem I have. I too was using Oxygen 2.1.6 and lost all connectivity. I've just locked my bootloader and flashed back to stock ready to send for repairs. That rom must be doing something >.>

I've been trying *everything* for last past few days. Nothing is working. That shouldn't stop you from trying though. Just stay well away from ODIN and those i9023 files, I've seen bad things.

Ok, it'd be great if you worked something out. I'm so glad i'm not the only person with this issue!
Anyone had any breakthroughs? *hopeful*
I wouldn't call it a breakthrough but I got somewhere!
Ended up putting a extremely thin piece of wire into the external antenna port at the back of the phone. Wasn't too keen on doing this, but my phone now has reception isn't stuck at the dreaded -113dbm.
The reception isn't good, but it's enough to send texts and have calls.
Although the area needs quite good reception for me to receive anything, and it's extremely sensitive. To get 3 bars in a place where I usually get full bars, I have to be outside. While inside it's reduced to none or 1 bar, which is enough to send/receive texts and a sort of lagging phone call (did a few tests). As mentioned before extremely sensitive. The phone seems to like it better when it's up-right. In the middle of the CBD at Brisbane I get full reception and 3G, which is fine but in the places where you usually get 2 bars, you get no signal at all, unless you're outside.
So this is hardly a fix. I will most likely be sending it to Samsung to get it actually fixed. Either that or get it fixed the same day and pay probably close to $100 so I don't have to wait 2 months waiting for Samsung to twiddle their thumbs.
Thats awesome! But I'm going to post mine off to Samsung USA tomorrow, which will take forever considering international shipping. Where could you get it fixed same-day? I'm going to try this wire thing
So it can't be a software issue, but maybe the rom overloaded the antenna and fried it or something? I'm glad we've got that far.
I've seen that nexus s has a problem like the iphone, the antenna gate. Try take the phone with the left hand looking to no touch the rear of the softkeys

Its more serious than that my friend! Thanks anyway
I got a quote from a place in Brissy called "FixMyMobile" and they said if they can fix it, it will cost $99. Although I'll get quotes from different places (if I find them) and see what they charge however I don't think I will be able to get cheaper, most likely around the same price..
So I may do that to not wait the ridiculous time it will take to get it back from Samsung.. Not sure on places in NZ though.
Yeah it seems like a hardware issue definitely. I eventually reverted the phone back to stock everything and it still happened, so that there shouts hardware issue.
Hello everyone;
I flashed the latest official 2.3.5 last night. Missed three calls afterwards, as if I was not connected to GSM network. I was at home and signal was stable as usual. Anyone else noted unusual GSM behaviour?
Cheers
----------------------------------------
UPDATE: In order to better understand this issue, it could be interesting to know which service providers are being used; in my case, TMN in Portugal.
One week before flashing this ROM, I started using 3G, so I'm not sure if these missing calls are as result of the ROM change. I'm going to switch back to 2G for daily use and see how it goes.
Yes, if you search you will find other users with the same problem.
happens also with the other beta roms.
Sent from my U8800 using XDA App
It happens to me too unfortunately.. can't tell the reason why. GSM status seems ok.
I confirm this missing call issue.
People when ring me the first time they go straight to voicemail and only get connection on second try.
I think the only way to solve it is Huawei but there is not point of trying to speak to them and they just won't listen for what people say to them.
I can confirm this is happening to me too....after reporting all was well this was one of the things I didn't test out.
Weird thing is that I called my mobile from home and both went straight to voicemail...
yep.
but if you immediatly make a 2nd attempt you get connection
OK try this...
Turn off phone... re move battery and sim card.
Replace battery and start phone without sim card and boot up.
Unlock phone and open any app (doesn't matter just do something)
Turn off, remove battery, replace sim.... boot up again.
Just called from my wifes mobile phone and my phone rang OK.... will test further but that seems to have done the trick for now.
I got the same problem and so far nothing i did solve it... Just missing reinstall the rom again and see if wasnt any bug i got while installing... I don't see too many ppl with the same problem and i don't belive huawei had so many diferent hardwares in a single mobile phone model according with all the different ppl have with different phones.
I also have this problem with the new firmware. My phone doesn't connect to the network upon powering on.
I have to manually connect it, by going into the Mobile networks settings. Once i'm in that menu, it connects.
druida_69,
I can confirm that does not happens every time, I tested from other phone I only on the sixth call I got the ring... Worst, during this time I made a call without problems.
The question is on reception...
Sent from my U8800 using XDA App
this issue is killing me.
when I have the device disconnected or in a cal, when someone try to ring me and can't I always receive a message informing that the xxxx number tried to ring you at that time bla bla bla.
no calls
The same thing happened to me... also tried many things without success... downgraded to 2.2.2 (B138) problem solved...
I'm getting tired of huawei's poor support and buggy updates!!!
To be honest i don't know if this start to happen after or before installing geno‘s OC Kernel.
I can confirm that this happens when the phone stays for a long time inactive. Try not playing with you're phone gore 20 minutes or so and then try to ring youselves.
Its like if the phone entering in a zen deep sleep....
Same here
Started after updating to 2.3.5, anyone tried the updated 2.3.5 from Huawei? it removes the pink screen I heard, but maybe it fixes this issue
F****** Huawei. Just realised that I have this bug too with latest 2.3.5 release... I think that it's data dependent. If you turn them off it connects ok...
I didn't realize until I read this thread, but I have the same problem!
I'm over it, I'm going back to Oxygen until I can buy a new phone, and will probably never buy huawei again.
I had this problem initially but since I booted up without sim card and boot up again with it in hasn't been a problem...I've had to test this on a few different phones & reboots now and everything is fine....

Hi all,
Regular reader but hardly ever post!
I have a Galaxy S4 (GT-I9505) - with Android 4.4.2. Unrooted.
Purchased and used in Singapore on the Starhub network since around October 2013. Everything was working fine until approx Feb or March when the latest Android version, 4.4.2 got rolled out.
Ever since then I am experiencing regular disconnections from the network. But the phone does not re-connect back to the network again, the only fix is to restart the phone.
These disconnections are often once or twice a day, and are very frustrating because if I don't notice it, I may be off the network for hours before noticing it - and are therefore missing out on calls emails etc etc.
This only happened after the Android 4.4.2 got rolled out, so I am pretty confident this is the cause of the problem.
What I tried myself to fix:
- restore APN's back to default state
- Factory reset (both via settings, and via boot screen)
What I have been able to narrow down troubleshooting, is:
- Disconnects seem to only happen when Network Mode is "LTE/WCDMA/GSM (auto connect)"
- If I use network mode "WCDMA/GSM (auto connect)" the disconnections have not happened (yet!)
- When the disconnection does happen in the first mode, I cannot manually change the network mode. The radio buttons are greyed out, and if I try to select "WCDMA/GSM auto connect" the request times out (I forget the exact message - it does respond to the tap but then nothing happens)
So it seems to me this is some sort of software bug/fault introduced with Android 4.4.2 that affects 4G connections.
After that, I have taken it to Samsung for warranty service. I have now had 4 visits to them and they have not been able to fix it yet. This is what they have done so far:
- First visit - factory reset (despite telling them I already did that) - did not fix
- Second visit - checked hardware and replaced mainboard. Did not fix.
- Third visit - checked hardware again and factory reset again. Did not fix.
- Fourth visit - who knows. I think same as visit three but done via a Service Manager instead of staff, Did not fix.
When I first called them back in Feb or March, they said it was a "known Issue' and sugegsted to "wait for a patch". However since visiting them, they said the known issue was only with Note 3's (not with S4's) and replacing the mainboard on the Note 3's fixed the problem. In my case replacing the mainboard - twice - has not fixed it.
I'm getting very annoyed with Samsung who seem to just be trying the same thing each time and are not fixing it. Staying in 3G only mode is a workaround but not an acceptable solution.
Now they've asked me to take if back again - for a 5th time.
Beginning to wish I had never bought the S4, or at least never got Android 4.4.2.
So I thought I would turn to here for help instead, I think you guys and gals probably know more than the Samsung service staff!
Any suggestions?
By the way, I don't run any memory/battery saver apps. I do run one data usage monitoring app that I thought perhaps was conflicting, so I tried not installing it after one of the resets, but the problem continued.

you CAN try other modem flash, but be careful with your warranty.
I do not know about the warranty conditions in your country, but in EU normally 3 unsuccessful repairs = phone refund or replacement.
I would try reflashing stock file or just flash a different modem
Hello, just like you i have been reading the post but never posting because i just came here to learn, nothing to share from this side...sorry.
But i am having the same problem as you. I bought my phone in Switzerland on march 2013 but i live in Uruguay. I was just thrilled with my s4 until the 4.4.2 update came out. My connection keeps on crashing and it doesnt matter if its on 4g or 3g just make me miserable all day. Only the two of us is having this type of problem??
I believe is some kind of issue with the new bootloader i just updated with a patched rom that came for Germany last week (the one with kids mode) the phone work fine for a hours and then crashes, so this update didnt work. I have also flashed very differents official roms and modems but nothin seem to affect the problem.
I have another problem even though my s4 is 4g i cant connect to 4g network, every configuration is fine i just cant connect, any thougths??
Thank you very much.
Sorry for my english.

I should add, I took it in *again* to Samsung, to the Service Manager. Said they would replace the antenna and try that, which they did.
Still have the same problem though.
Not sure who to believe, Samsung are starting to run out of ideas and starting to say it may be a network issue. But if the network is down, then the phone should automatically reconnect once the network is back available again. And it doesn't.
I'm convinced it's a bug introduced with KitKat, as the problem only started then, but of course I cannot prove it...

Sounds very similar to my problem, that it just started with Kitkat only. I'm sure it can't be just us two having this problem! I don't have anything special or different installed on my phone, and it's too suspicious that it was working fine, 100% perfectly until the KitKat software came out...

I know it just cant be the two of us from such diferent places in the world but, i just cant find any similar in any post or google. It has been almost 3 months from the update an me using another phone...
Well I thought I would post again to close the loop.
After Samsung tried 5 times to fix my phone, checking hardware and trying to reinstall the OS with no luck, they suggested I try replacing my SIM card.
Surprise surprise, it has fixed the problem with no recurrence yet after a week so far.
I still don't understand how the sim card could be the problem, especially as my phone was working perfectly right up to the Kitkat software update. All I can assume is somehow KitKat either had an incompatibility with my simcard (maybe the new sim is technically slightly different?) or maybe KitKat somehow changed something on the simcard, if that's even possible.
Interestingly, I did contact my telco first, and they told me to contact Samsung. As it turned out, the fix was in the control of the telcom right from day one.
Anyway, so far the problem is resolved, so I thought I would post this here to help anyone that may have this problem.
Hi guys, i know this is a common problem, but i have yet to find a solution to it. My S4 (Bell Canada, KOT49H.I337MVLUFNI2, completely stock unrooted) will drop the mobile network (both voice & data), and the only way to get reconnected to Bell is by rebooting my device. After a reboot I might be good for a few hours or for a few days but it always happens again. At first the mobile signal will grey out, then eventually turn to a circle with a line through it. In the network mode setting becomes blank and non-selectable.
Suggestions around the web include selecting WCDMA only, clearing the cache, factory resets, and reflash the full firmware package with Kies3 & Odin. Ive tried them all and the problem always inevitably returns.
Here are a few links to people with similar problems, but nobody seems to have a solution in any of these threads either:

Other than returning it for a replacement under warranty, does anybody have any other suggestions to fix this? Thanks.
anyone?
Are you sure your problem isn't the same as the sim card removed problems? Because the symptoms sound the same in the effect they have, and what is required to temporarily fix it.
See here and here.
I've experienced the same problem, but it seems to have cleared itself.
It first started happening after the update to the latest Bell stock firmware.
I had read some people blaming it the Amazon app store as well as the Skype app. I had both installed, but have since removed Skype but can't say 100% that this is what solved the issue for me.

I have the same problem, this is not the sim card removed problem, this is a bug in Android 4.4.2 because the problem was not present in 4.3 maybe the recent update to 4.4.4 solve this, has someone try out ?

My SIM card is still in place and detected, the phone just disconnects from the network. After a reboot it will be fine sometimes for a few hours - sometimes a few days, but it always inevitably disconnects.
If you check any of the several links I posted you'll see there are hundreds (if not thousands) of people on all different carriers all experiencing the same problem.

I've had my device since Jan of 2014 and the problem only appeared in the last few months following the 4.4.2 update.
I'm having the same problem. It disconnects and reconnects again. Stays disconnected for about 2 mins. Happens like 12 times a day. I re enter the apn setting and still does it..it happens with every rom I flash. I've notices that it mostly happens when it switches from 4g lte to 4g. I'm on At&t 4.4.4
bump. anyone ever find a solution to this?
So I have a Huawei p8 gra-L09 with Huawei P8 [ROM][6.0] fRomFuture - Home that I installed a couple of months ago. Everything has worked perfectly up until recently when my phone does not find any 3g networks, only 4g. When I try to make a call it's stuck on 4g. I don't even know if my phone is the problem or if it's my carrier. I tried to call them, they said they "made the network better".... But the problem came back after 1-3 days again.
Can I solve this somehow? My phone is also rooted but that doesn't really matter I guess..
Check the fRomFuture thread, another guy in that thread has the same issue..
did you managed to get the issue resolved?
Well, nope. Turning of 4g sort of fixes the problem I think. The connection drops sometimes but most of the time it works. Also I changed to stock b392 because I could not turn off 4g in the build that was used in fromfuture - home for some reason. It automatically turned it on just after chabging to only 3g/2g.
Still doesn't work as intended though and I am 99.9% sure it is not because I don't know how to flash. Used adb and fastboot and unlocked bootloaders and whatever on so many phones since my first smartphone (htc wildfire).
Are you by any chance Swedish or scandinavian? Could it be that it is not compatible with the networks in some countries or something?

No i am in UK; i bleive the single sim version supports all the bands, at least here in UK; it is a phone i just bought off ebay and i can return it but I wanted to be sure it wasn't something that could not easily be fixed before doing so.
Hi again. I have sort of figured something more out about the problem. This morning 3G did not want to work again. So I googled, and googled and googled. Tried everything basically. Then I noticed that my APN settings are not what they were last time I set them(???). So I went into my carriers website. Set the correct apn values and removed any unnecessary values that did not seem to affect anything. Then it immediately worked again. Now I have no idea how phones sets the default settings but it seems like they are wrong? Maybe this was just random that it started working after applying the correct settings again. No idea, going to see if it works all day or if it randomly stops working as earlier.
Edit: 5 hours later still works and the connection hasnt stopped randomly.
Ok so it has worked for 13 hours. It's actually weird if the APN settings for 4g broke the 3g connection sometimes randomly throughout the day, right? I don't know how apn settings really work but I remember setting a port number and also changed the name of the APN so that I can be sure it does not change to something else.
ugh, I give up. Now it stopped working again since yesterday. It feels like it's my carrier but so many people have this problem so I guess it's something else..
Nevermind I don't give up. I found a solution . When 3g/calls stop working the phone usually gets really, really hot. So putting it in the freezer for a couple of minutes actually fixes the problem for me, atleast until the phone gets really hot again. I have tried it four times now and every time it has worked.
