I have my sgs for 2 weeks now. GSM disconnects around every 2 days.
At service mode (*#*#4636#*#* - Phone information) i can see this repport:
GSM disconnects:
====DATA=====
State: inactive
disconnected with last try
at 00:59
fail because No Error
The question is: why does this happen?
Is this an android issue or a hardware problem?
Any pointers?
Thanks in advance
.
do you ever enter a building, subway, or some other location where the GSM becomes poor?

That's not the problem.
Gsm disconnects just like that ,at home for instance. And when I notice that and try to reconnect (settings- wireless networks- mobile networks - networks operators) it doesnt find ANY of them.
Then I restart the phone and gsm network is back.
If I dont notice disconnection in time (so I can restart phone, people just cannot reach me....quite frustrating...
i see what you mean now.
yes, i've noticed that on mine too, but.... that's because i was fooling around with some new Apps Widgets settings i was testing to control the radio and data to save battery.
Did you install any new Apps recently that might cause that?

do you have an old sim card? i had a 3g sim card that wasnt even 1 years old and replacing it fixed connectivity issues on my nexus 1 and i had a similar experience with my old htc magic

Well I installed all kind of apps. but i have the feeling this problem was happening even before that.
And I dont need widgets to control data ( I think) because I set the sgs to use 2g networks only and I dont have apn configured( section is empty. Internet connec. only via wifi.

Well, my sim card is VERY old (2002) and the carrier (Telfort) is roaming into another carrier's network (Kpn) with no extra costs of course like real roaming, but still roaming (I get the little "R" next to the signal strenght bars)
Anyway this never happened with the Nokia 5800xm running Symbian OS and using the same sim card...
Starting to get pissed of with Android...
With Symbian you hack or root or tweak because you want to, not because you NEED to like with Android....
And then you prob. get side effects...
Thank you guys for your time
I would get a new sim card if I were you. Every android phone that I have had seems to work better with a good 3g sim.
Get a new SIM card.
same problem, different phone
i have the same problem on kaiser with flashed android on it.
sim is 2 years old, and now suddenly this happened, tried differents sim cards, but the problem persists. My guess is, it is a software problem.
Maybe i will report when I flash original WM6.1 rom onto it, if you are interested in the result
btw, this happened about two days ago and because of this im buying galaxy s so i hope the problem will be gone with new phone
did you guys see this other topic?

Why you think the problem will be gone if it's still android and I also got it with my sgs? Or are you counting on Froyo?
Yesterday I upgraded my sgs to froyo jpc with kies. I am new with Android but the post of Aery was so clear that i didnt resist: http://forum.xda-developers.com/showthread.php?t=769400&highlight=froyo+upgrade
I did get stuck on reboot but could get out of it after applying a cache/data/factory reset on recovery mode (3 buttons)
Now I am being carefull with the 3rd party apps., and so far so good, no gsm disconnections .
Froyo is of course better that eclair but Android is still disappointing to me.
You flashed Android onto a WM device (i'm impressed); could you not teach me how to flash Symbian onto my SGS?
Voice dialing (over bluetooth or not) and proper connectivity control (network, data, gps and bluetooth) of android is years behind Symbian; and such a well written, light OS, it will just fly on a high-end hardware like the sgs; but that is an issue for another thread.http://forum.xda-developers.com/showthread.php?p=7938430#post7938430
Pls keep reporting..

I think indeed that's not the same issue. My problem is that the radio signal get turned off during inactivity. That's why I got connection back after reboot: radio signal gets turned on again; later I learned how to turn radio signal back on without rebooting, but that is just a remedy , no real solution.
Try to upgrade to froyo, make a factory reset and be carefull with 3rd party apps. With froyo you will need less interfering tools anyway
I dont thing that my old sim card is the problem, but i'll try to replace it anyway...but first things first
Btw dou you have 3g turned on? Cause I never...
Another mistery: When I have 3G on I see those bars (signal strenght) dancing and that "death grip" thing happening:http://www.youtube.com/watch?v=LROTHrTR92k
But when I have it on 2G only the bars doesnt move even if I strangle it with both hands.....
Please repport later how it's going...
I had the same issue, i sent mine back and got my money back, i had also tried with different simcards and resets and nothing worked.. so hopefully my new galaxy wont have this problem. Its strange that these problems are so rare though.. But as long i get it going ill be a happy man.
fourth day with JPC ( and 4 days after a factory reset) so far so good no disconnections . I think problem is gone...
Today just to be safe, I got a new sim card....the other one was too old anyway(8 years)
i have the same issue, for a few days i can't get 3g. i'm seriously wondering about sending back my sgs. i've ttried all the settings, changed my sim..nothing...begin to think it was a fullish thing to change Desire to SGS..

Well... this is not the same issue.
I have 3G (WCDMA) disabled. I only use 2G (GSM) and WIFI for data/internet connection.
I Dont have a data account, I dont need it therefore I disabled 3G in order to save battery.
If you do want to use 3G, just go to settings - wireless and network - mobile network settings - network mode and set auto-mode (GSM/WCDMA or 3G/2G)
If it doesn't work, apply a data/factory reset and try again.
And if it doesnt work, it's probably hardware related and you should return it or send it for repair.
My issue is more complicated; next to the fact that I dont want to use 3g, my carrier is roaming to another network and probably Android OS or the firmware cannot handle it properly.
Android is still premature and the "Samsung - Android integration" seems to need a lot of development as well.
It is just a shame that basic functions like proper connectivity control just wont cut it. And Google is not doing any good either.
And dont let me get started on the voice recognition issue......
Hardwarewise, the SGS is superior that htc desire.....I wonder how it would perform if running Symbian^3 OS or Meego.....
I get a great sound quality from the stock music player just by mixing the equalizer and using the music clarity effect...just great...better than any other device I tried.
And the OFFLINE Gps experience is just great as well: the combination SGS - Motonav - External Bluetooth gps device is working like a charm.
I wouldn't change my sgs just yet......
yesterday i was swiching sims to determine if is a sim fault and suddenly i have my 3g/h back. happy owner again. i've tried all to do this, from firmware upgrade to servide mode settings..i don't know why but i'm ok again...

Hello,
I know its been a long time since you wrote this thread but I just came by it!
I have the exact same problem with you (I had it since August) even now with the official froyo. I tried factory reset and no new apps (that could cause the problem) but it still disconnects randomly in GSM mode. However, when I have it on auto (gsm and wcdma) I have no issues. I just disconnect data from the power button in froyo. I am wondering if you ever found a solution..
Chryssa
Well, I am subscribed to this topic so I saw your post.
Good and bad news:
First the bad one: No solution yet, it keeps disconnecting IF I stay on "gsm only".
And the good (or a little better) news:
I noticed that on sgs, using "gsm only" or "gsm/wcdma (auto mode) makes no difference on battery consumption....
By the way, this is a Samsung issue, not really an Android one.
On a HTC Desire HD, you can use "gsm only" mode with no problems...
Thank you for your answer!
I noticed that about the battery too. So not too bad, I just have to keep it on auto mode then..
Same issue
Im having the same issue but in a optimus t the worst part is that i cant get service at all.. when i press change network preferred it wont change and when i try to press on turn on radio it wont work either....
I've tried a lot of builds from this forum (thanks to everyone who worked on them) but i noticed the following issue which i really can't understand why its happening.
the network connection does not work in all locations. i'd assume its a problem of the operator but.. if i reboot to windows mobile it works fine. i always experience the problem in the same locations (usually out of town) while when in town it works fine.
why does this happen? why is windows mobile different?
p.s i'm using the 2.12 radio.
try to set "aiplane mode" on and off... your network connection must be work.....
It's some problem for me..
same here. i've tried a plethora of builds and a couple of radios, but some builds have connections that work well and others work intermittently at best.
i have only been running an full nrg rom, but then everyone always yells that windows isn't running underneath anyways
+1 tried 2 builds and about 5 different radios... Phone with no data connection is a bit poor
Have you guys tried all the possible on/offs in windows before you boot through?
Cheers
make sure data roaming is on, and GSM/WCDMA switch is auto.
then turn on airplane mode, and switch back.
unfortunately i tried all of that. mainly i even tried rebooting the phone in windows, checking that network works, then rebooting again and starting android (just to make sure it wasnt affected by wm) and trying to get a network connection but still.
its puzzling cause this doesnt seem like an instability its more of an inability to get a connection when the signal is low or in areas that possibly run a slightly different kind of mobile network broadcast? (i'm not really familiar with how the network works..)
found the solution on this end. I am in France, so needed to modify the last couple of lines in /system/build.prop to point not to google (I assume), but to the local operator DNS.
Great stuff guys, I'm amazed!!
that could be it. how do i change build.prop from within android?
I am very curious to which lines you changed, and where you exactally changed them to. Please share, this been buggin me for weeks.
mine problem is my 3G network connection is very slow..... someone know how to solve this problem? i'm using radio v2.14 before & now v2.15 seems like same problem...
I changed the build.prop using builddroid: Install, connect phone in android in usb debugging mode, change the build.prop and transfer the changes onto the phone and reboot.
Here the last few lines of the build.prop I'm using. The dns's are provider specific...
Code:
name=Android
dalvik.vm.stack-trace-file=/data/anr/traces.txt
net.ppp0.dns1=62.201.129.99
net.ppp0.dns2=62.201.159.99net.dns1=62.201.129.99net.dns2=62.201.129.99net.dns3=62.201.159.99
Hope this works for you too
Thanks for the share , im in school right now, so im gonna try as soon as i have a window of time ty in advanced
Hey,
Could you tell me where you find that dns ip?
The only ip I could found was this:
192.168.251.150
But I highly doubt that its correct, because its so diffrent from yours, also my 3G didn't work with this one.
If you could help, would be great.
Hi,
I apologize if it's the wrong forum or if I missed something in my search over the forums (and internet).
Current setup :
HTC Legend rooted, flashed with Azure 1.0.1 (cyanogen 6.0)
Kernel 2.6.29
Baseband 47.26.35.04u_7.05.35.26L
Issue :
For some reason I can't get my 3G connection stable. eg. When I enable Wifi - 3G drops (which is set up that way), but when I disable Wifi 3G doesn't come back up. Even though the settings are correct.
I'm having a hard time getting any mobile data correctly going, it generally requires me to enable/disable wifi and reboot the phone several times.
Basically I've tried factory resets, checking the settings (config of mobile networks too), it doesn't stay in 2G mode, ... I've test with other Cyanogen based roms and it's the exact same issue. Is it possible this is due to a radio being wrong or is it possible it's actually the phone?
So:
- 2G only is DISabled
- Mobile data is enabled
- wifi off
- settings (mobile connection parameters) are correct
- tried different roms
- checked in places I know I should get a good connection (My provider is Telenet, they use the Mobistar network, my previous provider was mobistar. So the coverage should remain the same.)
I am at my wits end and do apologize if this is a stupid question, but I can't think of anything else that could interfere with this.
Have you tried to leave the 2G/3G settings by default? That is, not to disable 2G. It is anyway switching to the best it can aquire, so if you have strong signal you should get allways 3G. I never had these problems with any ROM I've tried...nightly, Azure, RC1/RC2

Quick solution : put one of HTCs widgets for mobile network on your homescreen and as soon as you turn WiFi off toggle the mobile network widget and 3G should start working again . It's a hit or miss though.

Must have used the wrong keywords >.< Sorry. Though thank you for the link, it is EXACTLY the prob I am encountering. At least now I know it's not the rooting that caused it.
About the HTC widget : I've used it, but it's indeed a hit or miss. Best solution seems to switch to 2G and switch back to 3G that way.
Leaving all the settings at standard (and the most recent flash to the CM RC1) helped with the overall connectivity though.
Hi All,
Since I got my DEFY I have WiFi problems. This issue only exists when WiFI has WPA/WPA2 PSK authorisation.
It is going like this: I connect over the wifi. Then connection works fine, I am able to browse www, check the emails etc, and after few seconds, minutes the connection stops working but still exist. I try to reconnect several times. Defy shows that is connected but nothing works fine. Internet apps or Market gives a message like the time is up, connection lost. I have to forget the conection in settings or reset device to get it working properly, but not for long.
And the thing is that there is only ONE ROM that works fine with WiFi on my DEFY. This is Cyanogenmod-7.1.0-RC1. Other ROMs have same issues. Doesn't mater if it is Cyanogen mod 7.1 stable or any MIUI or MS2Ginger. I tried almost all roms but nothing helped. So I had to go back to CM7.1.0-RC1.
Do you know what should I do to make WiFi working fine on other roms?
greetings,
Gregory
p.s.
Please, just don't tell me that I should change authorisation on WiFi router. This is not a solution for me, because I use WiFi in a lot different places.
Same problem
Hi,
I have the same problem with my Defy since a few months, no solutions!
I have the *EXACT* same issue. Was about to roll back to stock and send it in for repair, glad I found your post! I'll install the ROM you suggested and keep hoping this gets fixed
just fixed my wifi issue for the second time. If there are to many remembered networks no more wifi. You can turn it on but it cant find any. delete all remembered networks and back on line. that is the only conectivity problem I have ever had after months of cm7

I think that's a different problem than we're having. It is finding the network just fine (and connecting) in our case. It's just that internet connectivity refuses to work after a few minutes, forcing us to disconnect-reconnect to get it working again
@OP: Thanks a lot! The ROM you mentioned does indeed not have this problem. It's not as stable as some of the more recent roms though, think I'll still be forced to revert to stock
i had exactly that problem with my first defy, no solution man, i send it to warranty and they give me other
maybe changing the regulatory domain channels from 11 to 14 could help. this option is hidden by default, you have to enable it: change the value of 'ro.debuggable' from 0 to 1 in /system/bootmenu/config/default.prop, save and reboot. after that, the regulatory domain setting will be shown in settings/wireless/wifi/advanced. simply change it to 14 channels.

OK, maybe I just passed the signpost but... do you still have the problem if you set your "select network" setting to 3G only?
I ask because (and it may be different on my phone as I am USA, stock ROM with wifi calling) if you go into the INFO menu > phone information > set preferred network type, mine toggles between three radio preferences: "GSM only" (when wifi is active), "GSM auto (prl)" and -- if I set for 3G Only, "WCDMA only".
I have noticed that when "select network" setting is at automatic (or 2G only) it often has trouble transitioning from cell to wifi. And, when wifi is an issue, I find that "GSM auto (prl)" has been selected (which on my USA phone prevents wifi connection). However, it seems to have no issue whatsoever transitioning from "WCDMA only" (3G only) to "GSM only", which on my phone then allows wifi connection. Again, this is a wifi calling phone so may be different.
Yep, same here BUT ! I get root browser, found my build.prop and change wifi chanells first time for 14 and it didnt help so i try other and my wifi works in 100% with 13 chanells. Try it
This is a widely know problem, many people are affected more or less. I'm also having nerve-blowing times with wifi sucking all over... Stock Froyo (and now Cyanogen 7.2) seems to be a bit more stable, sometimes everything is fine for a few hours, all downloads go lightning fast - and then suddenly things are screwed up. I tried a lot of MIUI releases as I like it most. MIUI seemed the most problematic so far. I don't know what is the cause, new stock Motorola Gingerbread ROM versions also have this issue (except one I think - look it up in the forum).
Agree, bothering with the router is not a solution. My Nokia E51, my EeePC, my girlfriend's Omnia and Lifebook - all work perfectly with all the four routers we use frequently. Not a single glitch - everything is stable and nice, except Defy.
I don't think is a hardware problem with certain devices, it seems more to do with the way Defy handles wireless connections.
Anyway, it's frustrating but CM7.2 and CEE Froyo gives a bit better experience than others.

Which Froyo version do you use? A few times this wifi-bug occured also under Froyo. I'm thinking about going back myself, as Froyo is the only acceptable release to record hiccups-free videos
After a couple of days of using my Nexus 4 i've noticed a problem with the way it handles the transition between Wifi and 3G internet.
Usually it works just as expected, when I switch Wifi off (or just go out of wifi range) it automatically switches to 3G internet (coverage icon in blue). The problem is that sometimes, after switching wifi off, it doesn't turn on 3G data (coverage icon remains grey). The only way I can get 3G internet back is turning Airplane Mode on, and then off again. ¿Am I missing something here? I've seen other people having this problem with other phones, but no workaround yet

This happens with my gf's Galaxy S3 too...
I think this is just a network coverage issue. My old mytouch 4g slide had the same problem. Usually it switches quickly if I'm in an area with great reception. If I'm somewhere with weak reception, it takes a little longer.

Well, I don't think this is a network coverage problem because when this problem happens, it can stay for hours with no 3G internet, it just doesn't even try. But then I switch airplane mode on and then off again, and it achieves 3G data connectivity almost immediately. Also, with the same SIM card I didn't have this problem with an iPhone 3GS.
Well, i've been investigating a little bit, and I've just found it in the AOSP issues tracker as "Android Issue #2207"
I've also found some apps like "3G Connection Fix Free" that seems to try to fix it
I'll try them and report back my findings
I think I have this problem too sometimes. I think my phone has other issues, I'm about to send it back to Google because it keeps dropping cell signals as well, but I definitely have this same problem.
Yes, it happened to me as well yesterday.
After I had more than ten hours at home using wifi, it can't switch to 3G automatically when I left home. The only way I did is reboot the phone.
But if I just connected to wifi for few hours it is OK.
Before I use One X, I don't have this problem before, but the problem is I can't access to internet once I am using wifi for more than 36 hours about.
I think there is big problem for Android system related to wifi and 3G access.
I don't think it's a nexus issue at all. It is definitely something else. My phone hands over form wifi to H+ in a matter of seconds every-time.
I believe you might have a coverage issue.
I am having the same issue, and can confirm it is NOT related to coverage. A reboot of the phone will immediately fix the problem. Have also tried disabling the mobile network, then re-enabling it, with no success.

Well, nothing i've tried has worked so far. It looks like if it stays connected to Wifi for many hours (for example overnight), it just won't switch to mobile internet unitl I reboot or do the airplane mode trick. I also have wiped everything and reinstalled the stock rom, but the problem is still there. Has anybody fixed it?
Had this problem with my Nexus One, with my Transformer 300 and now with my Nexus 4.
I use German provider O2 and after doing some research, many people suffer this problem and have O2. I thought it was related to my SIM card and I ordered a new one without success. My wife has O2, too. She never had a problem, not with her HTC Desire, not with her Galaxy Nexus.
I worked around with free app WifiFixer Free, which connects to 3G every 60 minutes. This doesn't seem to work on Jelly Bean, though.
The problem is all but new and I am out of ideas. I now use an app that enters and leaves airplane mode upon leaving a Wi-Fi network. But it yet has to prove that it works...
Any news in here? have the same problem and don't know how to solve it. It's so annoying

I have this problem too. Completely stock nexus 4. It doesn't happen all the time but when it does its very annoying.

After a couple of days of using my Nexus 4 i've noticed a problem with the way it handles the transition between Wifi and 3G internet.
Usually it works just as expected, when I switch Wifi off (or just go out of wifi range) it automatically switches to 3G internet (coverage icon in blue). The problem is that sometimes, after switching wifi off, it doesn't turn on 3G data (coverage icon remains grey). The only way I can get 3G internet back is turning Airplane Mode on, and then off again. ¿Am I missing something here? I've seen other people having this problem with other phones, but no workaround yet
