No service after dropped call - Galaxy S I9000 Q&A, Help & Troubleshooting

I have the Bell i9000M unlocked and used with Rogers SIM. Nothing else has been done to the phone besides installing apps (got the sd corruption on my first i9000m after using Odin and didn't want to go through that again).
Haven't had any problems for over two months but in the past week, I have dropped calls and could no longer make calls again until I restarted the phone. I have dropped calls before (there's always a couple of areas on my drive home where I drop calls using any phone) and have always recovered. But just this past week, I can no longer make or receive calls after a dropped call.
Sometimes the status bar shows the blue circle with a slash, but that changes to white bars. But even with bars I can't make or receive calls. When I check *#0011# it doesn't show that I'm attached to a network.
I can go to an area with strong signal and leave the phone for hours but still cannot make calls. The only solution for me is to restart the phone.
Anybody have this problem and know how to fix it? I've been searching for days but haven't seen a solution.
Thanks,

I had the exact same problem on my first 2 I9000M's. The only thing I ever found was to replace them. It was annoying as hell and made the phone impossible to use sending or receiving calls. the second one was JH2 with the 3BR fix. Texting was perfect as was the internet (3g).
I searched and searched as well. But I was talking with a bell guy about it and he said it may have to do with an IMEI issue they have a master ticket open 3449667. I know you are on rogers now, but hope that helps in some way.

Thanks, it is very frustrating and dangerous since I'm usually driving when this happens. Unfortunately my 60 days are up and I can't get a replacement. There must be a way to fix it since it was working before. Maybe a SIM issue? I'll keep searching and hoping and if nothing, then I'll do a reset before sending for repair.

Just to update, I got a new SIM card and I don't have the problem anymore.

[Q] All recevied calls straight to voicemail, can't recieve texts, on Bell (I9000M)

For the past day I haven't been receiving any texts. I've tried 3 different friends phones on 2 different networks and 1 on the same network. I can send texts fine though.
A couple hours ago I tried calling my phone from a land line and noticed it goes straight to voicemail. I can make calls fine as well.
All the settings look fine on the phone, is there any special codes to enter to further check things?
Bells customer service is gone 'til Monday....
did you unlock the phone, or using any TurboSIM card unlocker?
Stock rom, not rooted or done anything like that. The only new apps I can remember using yesterday is the bluetooth module for astro file manager and trying the bump app with an iphone. Does that work by the way, android/iphone bump app? It wasn't for me.
Also, a reset to stock from the privacy menu hasn't helped.
yes i have bump installed, but so far not seen any iphony user with bump to try it on
are you able to receive phone calls if you put your sim card on another phone?
Finally got the number for data support from one of the local stores and they were able to fix the issue which was something on their end.
Yup, that just sounded too weird too be a phone issue

Bell has been having outage problems. It's probably due to the surge of new users they're getting because of the SGS. I called them up and they reset it for me or something.

[Q] galaxy s certain people cant hear me

Just got the new phone and calling all day, there are 2 people that cant hear me at all, but I can hear them just fine. Once it happened in the middle of a call.
Anything that could be causing a conflict? Any fix?
Today, after a week of issuing the phone, one person called me four times in a row and we couldn't hear each other, then I called him back and we had normal conversation. Maybe it its network problem, or something else?
Sent from my GT-I9000 using XDA App
I dont think so as none of my other friends are having the issue and they all have the same carrier
every call I placed recently, after a few minutes it mutes my end and the other person cant hear me but I can hear them
Im running JM5/JM1/JM3
If the firmware is the case, is there a way to downgrade it? I'd rather wait for Froyo official in my area before messing with it
OK I upgraded everything, the pda,modem, and csc and still the same issue.
I know its the phone as I put my sim in my iphone and it works just fine
I keep getting people calling me and hearing just silence when I don't even hear the ring, it's about every second call like that! When my wife with simple nokia doesn't jane any problems.
I get sms from carrier about someone tried to call that's how I know how many calls I miss.

I thought it was some conflict with the sms contacts, but I cleared it and still this issue.
This is the second phone I had. If I cant figure out this weekend, I think ill return it and just go to HTC cause this is just ridiculous. Wiping out the firmware and everything and still this issue...
Maybe its THEM, Sister had same problem with her Iphone 4. Turns out it was her callers at fault as their phones didn't support full Duplex calling or was in a congested area where the towers turned on half duplex calling mode. Theres simply nothing to be done unless you go and pay for a new cell tower

Flash it back to the original firmware, you may need to use Odin and search samfirmware.com for the original one.

Ill see, but I dont think they have my operator one.
I don't know if this is me or really I found the hardware bag but I noticed that all signal loses occur when my phone sits in my pocket face outward way. Also when I keep it in right palm at the bottom part of the device, I see signal drops by two three bars, look like there is antenna placement problem, or the device was designed for left handed user.
Sent from my GT-I9000 using XDA App
I dont know.
I think Ill return the phone tomorrow or send it for service. I had the provider check, and there are no cell tower issues, so it is my phone and it's only to one or 2 people I frequently call.
My provider firmware isnt on the website.
Is there a way to downgrade to one where Kies can automatically install a new one?
OK so I've been playing a game with the service center.
First attempt - sent it off for service with explanation. They put a new firmware on and thats it.
I tested it at the shop, and same issue.
Sent it back - attempt 2.
They ran some tests and didn't find anything wrong with it. Got it back yesterday and used it for about a hr before the same problems came back.
I sent it off again to a different service center. Hopefully they will find out whats wrong.
I still have the issue where the other party with either not hear me (every so often) or after a minute it will do it.
I don't know what to do. The service center claims theres no issue, but I do have the issue. I can't return it as here in Poland there is no buyer protection.
Do I have any recourse? Is there a way to brick it where they need to send me a new phone? is there any hope left for the phone besides a new paperweight?
Oh and it isn't because I don't know how to hold a phone. This happens when I'm using bluetooth and never touch the phone to answer the call

can't send: text message error

Hi,
I have had the HD7 for a few weeks now... before the nodo update i never had a problem with it but ever since then, i keep getting a lot of error messages for text messages saying the message wasn't sent. This usually happens when the signal is 1 bar or no bars (but signal is still there) and sometimes even happened with full bars.
Anyone else have this problem? I am with Bell in Canada
same also with hd7 in tmo usa
same problem 02 UK
However ive found that if i go into the settings and into the carrier options and switch off 3g, everything works fine , texts are sent and received and i have no issues
this problem seems to come and go for me so im presuming its the same deal that you have - when the 3g signal is low its unable to connect correctly - and since it has a 3g signal it dosent auto downgrade to the lower speed connection - so manually disabling 3g forces it to connect at the slower speed
hope this helps a little
feel free to tell me im talking bollocks tho - this is just my experience of the problem
No message errors here on O2 UK. I've had the HD7 since release & use messaging a lot. I don't get a 3g signal in my area, so that might be a factor.
Sent from my HD7 using XDA Windows Phone 7 App
Hey mate...Bell in Toronto area here. I've been getting the same thing, rather often tiotoo A few times I think it was due to receiving a text the same time or very shortly after trying to send one..it's weird though, pretty much every time I click to resend it goes no problem. You're not alone with that issue mate lol
phew ok awesome then... it hasnt been doing that for me ever since i started this thread lol, so i am a little happy for now... i am going to send off emails to bell and HTC and see what they say regarding this issue.
As per the 3G connection trick, as soon as i turn mine off, i lose all signal from the phone... the dialer just says "emergency only".
Thanks

Oh yeah that's right... i forgot Bell and Telus dont have edge bands. Hopefully the text messaging thing can be fixed soon... its getting annoying now.
I've been having the same problem. I used to send text messages in the loo's on my break, but now if I go there the signal is weaker and it fails alot. never used to before nodo.
This has been an issue for me since Day 1. My college is in a low coverage area and anytime im here, i sometimes get the error message.
I dont pay it much mind because if my phone is showing 1 bar or no bars, then it is obviously not the phone's fault(in my case) but the fact that I am just in a low coverage are and it struggles to get the message out.
This happens more so with my pic message than text message.
Sometimes people have also told me they have text me and I never received it or I'll text them and they never receive it.

did you check with anyone else in t-mobile that goes to your college? I do remember reading where people are complaining the hd7 has a weak antenna.
But even then so, 1 bar is no excuse for a text message to not go through.
I have the same problem. my phone will have full bars one moment then the next it will be down to one and "cant send: text message error" its annoying because i will reply and then look at my phone a hour later and see why they havent replied and the message didnt even send >_<
Some other times my phone get NO signal at all for a couple minutes then randomly has full bars again, its really irritating. I live in a college town where everyone here gets good signal.. no reason for this. I dont really remember it happening when i had the February update.
Ok so i sent HTC an email and this is the reply I got.
I understand that since performing the nodo update on your HTC HD7, you have been having issues sending text messages. I checked around with several of my coworkers and tried to find other instances of this issue occurring from other forums, but it appears to be a fairly uncommon issue. I took a look at the forum thread that you started and obtained more details such as this usually tends to happen when there is low signal. I see that some of the other posters recommended reverting to 2G in such a situation and that is not a bad idea. You can enable 2G only by going to Settings> Cellular. Additionally, the way you hold the phone can affect the signal as well. You may want to try holding around the sides so that your palm does not come in contact with the back of the phone, which can block the signal. Aside from that, you can also try a factory reset in case an issue occurred during the update and did not install properly or caused corruption in some of the files in the phone’s software. Please be sure to back up the information on your phone and the go to Settings> About Phone> Factory Reset.

I'm glad I am not the only one having this issue. (T-Mo USA) Mine started acting up last night with my 3G being EXTREMELY slow loading web pages and then ultimately not being able to load anything. Then this morning I am unable to send text messages, but randomly I will receive many emails and texts (like I only have a connection for a few seconds), then when I try to reply I am unable to send. Very frustrating.
i too have experienced this so here are some tips. For me i only get this problem when pressing send and right away press the home key or back key which interrupts the sending process result of fail sending. Enabling 3g if you dont have it is another problem so disable it. I also get this problem when locking the phone right after i press send so wait till it finish and then lock .
i hope this helps, if not restart the phone, and if that doesnt help take it to tmo and exchange =)
I've had this problem on my Omnia 7 since day one. Always have to disable my damn data.
And the ***** of it is when I go to re-enable data afterwards I have wait a few minutes to get it working again. Sometimes I have to turn the phone off and on in order to get data.
It's not a cell carrier problem since on my Diamond 2 I never had a problem, and the same thing with the x10.
Same problem with Samsung Focus on Bell. After NoDo update, SMS has been useless. I will get SMS, although often late. Sending is worst, I get the dreaded 'cannot send' message. I will occasionally be able to send some. Wondering if it's a signal issue. However, I can send just fine putting my SIM in another phone.
I've had T-mobile HD7 since last november, my girlfriend and I exchange about 30 messages every day, never had this problem before the NoDo update, not even once, no matter how bad the signals were. Im 99% sure its NoDo update causing this not t-mobile network. It's so annoying when you text somebody then go do something else, 20 minutes later you check back and see this un-happy face and can't send message.
BTW, Factory Reset won't help, tried that.

[Q] Vivid Issue Receiving the Calls

Hi I am using the ATT HTC VIVID from Nov 2011.
I bought this phone last Nov 11, and I stated noticing my phone was not receiving any calls if I stay at home(jersey city). If anyone calls to my number it will not connect at the same time it will not sent to voicemail also. It will say "call couldn't be completed".
After 2 months fight with ATT, they tried
1. they did a factory reset on my phone - it didn't help
2. changed the sim card - it didn't help
3. finally they replaced a another HTC vivid
even that didn't help
finally they said there was issue in near to my home and they fixed it.
now i a started receiving calls but now the new issue is, if I call to my number it will not connect first time it will go to voicemail, and second time if i try then it will ring. (First time also my phone is idle) This is happening randomly and ATT is not helping on this situation. As per them I am not able to replicate when they were testing on my phone.
Because of this issue I am missing calls which is making me really frustrated. After three week of research I found this is happening in not only near to my home its happening at my work place (NYC) and if I go around also its happening.
Can someone please give some advice to fix the issue that would be really great
Is there anyone else in or around your home with AT&T service? If so, do they experience the same problem as you? Can you receive calls everywhere else besides home and work? Do text messages get through? How about internet service? MMS?
Thanks for your response
The issue is not around my place
The issue is, if any one calls first time it will go to voice mail, if they call again it will connect to my phone. This behavior is happening randomly.
It is happening in my work place(NYC) and also if i go some where in new jersey also. I can't tell when its happening and how. In a day it may happen one or two time. I can't check constantly on a day when and where.
Sometime i feel I am not getting call, if i try from land line it may work or it may go to voice mail, after the second try then it will be fine for that day.
this issue look little weird. but because of that I am missing calls.
forgot to mention, that time my internet will work fine, how I am sure is one time i was browsing and trying to call my phone from land line it didn't connect. as usual second time if i try it did connected
Also the signal bar in my home and my work place its full

TERRIBLE Problem w/Dropped Calls - Need Help

Hey everyone,
I really need your help. I have a serious problem with my Sony Xperia Z 6603. I have spent too much time trying to troubleshoot this on my own so now I need your help and invite any if they have experienced the same. The synopsis:
At times, when utilizing my phone for phone calls, I got repetitive and persistent dropped calls.
Background info:
- City is Winnipeg of Canada
- Fido is my provider (essentially Rogers network)
- I have an LTE micro sim card (although Winnipeg hasn't had LTE rolled out just yet)
- I am rooted ONLY and on .434
- I have mobile network configured as follows:
- I use the LTE APN and select it on when in cities that have LTE
- Fido's website states this about bands:
Specs on the Z are as follows:
Now onto the symptoms....
The dropped calls occur sometimes when I am in a call, other times immediately when trying to dial out. An example would be, I'm driving and currently on a call, suddenly it cuts me off and my attempt to redial just keeps cutting me off from even placing the call. Wait a bit, keep driving, and now I can call again.
This problem happens in certain locations in the city. For instance at home I can be in calls for awhile, but there is this one part of the city for instance (just SW of the airport) and about a 2-3km radius that no matter what I do, placing a call is virtually impossible and yes signal strength appears normal. Also it appears that data is working normally. When I say impossible I will attempt the same call up to 10 times, each and every one dropping, some when 30 seconds into the call, others when immediately trying to dial out.
I also noticed that it also occurs while driving and talking for long periods. In other words, in a call normally and for a lengthy duration while transiting through the city and then suddenly drops perhaps while the phone is switching towers (a thought).
It's really bad. This is becoming impossible to tolerate and embarrassing to my customers and friends I speak with.
I downloaded an app from the play store called 'GSM Signal Monitoring' (https://play.google.com/store/apps/details?id=com.signalmonitoring.gsmsignalmonitoring&hl=en) to compile more information. Here are some screenshots but don't really know how to interpret the data. I see the db levels appear normal for a signal but not sure why the graphs reflect sudden spikes like that, perhaps my issue? Also notice in the graphs when the color changes for a new line, I believe when transitting from one tower to the next while driving. I was hoping some of you could perhaps try this app and compare what your results look like to mine, especially if you happen to be utilizing this phone in Winnipeg as well. Or if you know already, provide some insight on these results....
Things I have tried in my troubleshooting:
- Rebooting
- Switching DATA off completely (this seemed to provide a fix at times, but not at all times)
- Called FIDO and had them perform a "switch" or "network" reset of my phone on their end
Things to consider:
- The LTE micro sim is fairly new (upgraded it about 2-3 weeks ago)
- There are times when the phone works as it should and calls are placed and held normally (such as from within my home, SE corner of the city) but even near my home, while driving, I've had the calls drop but don't forget this doesn't just happen ONLY when I'm driving/transiting. There are spots where I am situated and can't place any calls without it dropping either shortly after or within 60 seconds of connecting.
I am really hoping that someone out there can help me resolve this issue or at least provide some direction from here. I purchased it from the UK so if it's a hardware issue I will probably have to send it back to the UK for the warranty to be honored.
Thank you for taking the time to read my dilemma!
Have you deleted any system applications?
Have you tried to use,2g only,3g only....

Awhile ago I used "App Quarantine" to quarantine some apps that I wasn't using. Since you brought this up though I had a look again in the quarantine list and also noticed the following 'com.xxxx files in quarantine as well which I never placed in there myself so I have no clue if that's normal or if they are associated with the apps I quarantined \, and no didn't select 2G or 3G ONLY, but I have switched DATA off entirely:
Not sure but could be some of this app is needed by the system,and causing the call drop.
Did you have this issue before rooting?
Best place to start is a stock no rooted firmware.
You can also try deleting fast-dormancy-wakeup.apk .odex
Or try 2g only.
Sent from my C6603 using xda premium
Thanks for the feedback. Just curious what the correlation between using 2G vs 3G would be with phone call reliability? And what is the 'fast-dormancy-wakup.apk .odex you are referring to?
Honestly I think I did have this issue before rooting but very difficult to be certain of this.
So I took everything out of quarantine and no changes. Still dropping calls.

I thought I was the only one in the world having the same problem back then when I first got my phone in march.... But it looks like yours might suffer the same thing as mine did. I live in Alberta.
My friend, when the call drops, does the signal appears to be resetting itself?
What is the longest call time that you ever have on this phone?
When did you get your phone, was it like that when you first got it
Sent from my Sony Xperia Z using xda premium
The feeling is mutual! There are times (or more specifically areas) where my phone behaves normally. In my home I can stay in a call forever. However about 2km away when driving on this particular road, at the same point every time, my call will drop. It does not appear that the signal/network is resetting itself when this happens (ie drops to no signal and comes back). I got my phone when it was released, actually this one is my second, I cracked the screen on my first one within a week. I can't quite recall if I had these issues from the beginning because as stated it happens when I am moving around.
I am now about to try to restore my phone to factory but before I do, I am wondering if I use the backup/restore app included, will I retain all my apps, their data/settings, and all my contacts and texts?
Should I use this app or PC Companion?
Do I need to do anything special or just use PC Companion for a restore to get back to stock settings (including un-rooting).
Thanks
I would suggest you to use the pc companion to repair the Rom. This will wipe all data from your phone just like the factory reset would.
If you did all these and found the phone still behaving like that, I think there might be something wrong with the hardware of the phone, it's highly recommend you return your phone for an exchange.
My first xperia z was like that, even worse I would say. Mine just won't let me call.. I never had the call time more than a minute it cut me off randomly, sometimes right away when the call was established, sometimes it cut me at 2 seconds..
When I got my replacement everything is just fine
Sent from my Sony Xperia Z using xda premium
Ya I figured it out. Just completed the restore with PC Companion. I did use the backup/restore function though to restore my contacts/texts/data/settings etc. Any chance you think by restoring this info the problem could migrate back? I can confirm I am not rooted anymore.
Now will test the phone calls. I will be in those areas where I know for sure my calls would drop, tomorrow. I'll report back. Really hope this works.
It might work. I do think it will solve the problem. Yours wasn't as bad as mine mine just wouldn't let me made any calls and the signal kept reseting whenever I call.
Good luck and will wait for your report.
Sent from my Sony Xperia Z using xda premium
Tomorrow I head to an area where it was virtually 100% dropped calls for me so I will report back how it goes after the restore/unroot.
No changes I'm afraid Still the same behavior. My next move is to take 2 other phones with me now, one being an iPhone 4 and attempting to use in those same areas. I find it very strange behavior on my phone's part and wonder if it's an area issue but these are dense, populated areas.
Frustrated......
Or what you could also try is to borrow a sim card from someone and then test in those areas.
Sent from my Sony Xperia Z using xda premium
I do have a spare sim card with FIDO. I just switched to the LTE card a few weeks ago. I guess I can call them and switch back to the older sim temporarily to see if the issue lies there. I will try the phones first. If I get the same symptoms with other phones, I will then try the sim card.
I have the same problem in about 4minutes my calls drop,doesnt matter were i am, on a side note dough,i use a normal sized simcard and cut it to fit my Z sooooo i guess my sim isnt playing nice with the Z ill get my microsim next week so i will report back and let you know if a completely new updated micro sim with lte enabled and ready is the fix
Sent from my C6603 using xda app-developers app
Thanks for the feedback, in a couple hours I'll be in one of those areas where I experience this and will try my iPhone 4 and then try switching back to an older Fido micro sim. I'll report this afternoon.
So interestingly today my iPhone 4 dropped a call in the same area. It also was having signal issues, cutting in and out, but managing to maintain the call too in various spots. So I'm starting to believe now that this may be a network issue with my provider and the area in question. I find it very odd though that it can be such a large and dense area. There is about a 2 mile stretch of this road where I frequently receive dropped calls. How can that possible in a city?? By the way I also swapped the sim cards when trying all this out.
Does it have anything to do with the fact that it's right on the approach path of a runway at the international airport, or near a military base? Keep in mind that I do occasionally get the dropped calls in other spots in the city as well but this area specifically is terrible.

Omg...runway...i experienced it aswel when i mentiont it yesterday now i think of it it was along side schiphol airport amsterdam a mayor one,it could be one of the sources of the bug,i think it could be more reasons in the equation like,old sim,no lte sim,thus maybe bad contact with sim,radio interferrence ect.ect.
I gues al those factors in on the call droppin

An update. Perhaps the most intriguing thing I have found so far but not exactly sure what it means.
If I switch my data to GSM only (ie Edge) the phone calls instantly become rock solid. No more dropping. As soon as I switch back to WCDMA mode (3G & HSPA+) the problem comes right back.
Starting to sound more and more like a network issue with the provider. I have relayed this info to my cell provider and they are looking into it and getting back to me.
Anyone else find this?
