Hello everyone, i'm asking this because it's the third time i had this issue. I often keep my Data Network Mode deactivated and turn it on only when i need because of my 3g plan (quota, taxes, and also because it's likely to find a WiFi network in the places i usually go).
The problem is, sometimes i turn on 3g (by Phone options menu) and... nothing happens... i need to reboot to make it work again.
The 3G network in my country is quite unstable, but i'm pretty sure that isn't a signal problem because one of the times i was turning on/off the 3G to make it work and i gave up and forgot to turn it off, the next day when i tried again i found it was On but not connected. After a reboot, working again.
Anyone having this issue who found a fix? Could be a problem with the kernel or app?
Edit: I Forgot: CF-ROOT Kernel, KF3

mate i am afraid you have answer already - "The 3G network in my country is quite unstable"
that can clearly produce the bug. Just in the case check your APN settings if they are correct. Settings- wireless and network-mobile networks- access Poin Names - compare the stats there with your network provider and make deep research.
just example i am on vodafone - i found that i was running vodafone live profile in APN and i was loosing conexion and i had troubles loading some pages - after research i found that there is another setup for vodafone as well - different then the live but for vodafone as well. i am using it since then and i am experiencing now the lighting speed of 3g. Just give it a try.
Searching on the internet i found that the configuration of my APN is equal to the recommended.
Backup data and factory reset phone should clear any software problems .
You could try flashing KH3 modem .

First of all i must apologize for not posting on development but im not allowed since this is a new account on xda...I live in London but im in mallorca spain for the summer looking for a job so having a phone is very important. As soon as i got my sgs2 i rooted it .. i was having some issues (random reboots) which led me to think it was either something wrong with the unstable kernel i was using or more likely a bye bye RAM. I decided to reset the phone and installed the LIGHTENING ROM... I Just love it!!! but... now im having trouble with it ... (BIG TIME) I had not realized something was wrong because everything seemed fine until i asked my gf to call me today... she couldnt... then i tried several times myself without success. I rebooted and to my surprise i started receiving a lot of work calls!!! (Which is great) but then i tried calling myself and it didnt work again. Im going back to stock firmware for now since the device is a phone after all. Dont know just yet if this will fix it but ill keep you guys posted... anyone having similar issues??
It might be a small bug in your firmware, try reflashing Stock and then see.. If still the same problem, try stock firmware from another source and reflash.. if still the same problem.. then its a issue.. Post your findings.. please
I have no issue like that.. just trying to help

check if your internet connection is set to wcdma/gsm auto mode...i am having similar problem when it is set to wcdma/gsm auto..it keeps loosing connection and radio switches off...making my phone unreachable most of the time.setting it to gsm only is the only way to cure this at the moment for me.

hi iznee;
I am from malaysia too.
currently I am using stock KE2 ROM. just rooted the phone for some xtra things that I want to do with it.
my phone is set to wcdma/gsm auto connection and never have outgoing/incoming call problem. Data also works as expected and by the way I am subcribed to Celcom unlimited Data plan.
by switching to GSM only, you are limiting the speed ability of the data to GPRS/EDGE only. please noted that you cannot have voice and data simultaneously while in GSM only mode. your Data session will be suspended if you make an outgoing call or if you receive an incoming call.
however, if you set it to WCDMA only, you can have both Data and voice simulataneously and that explain for 3G video call. but, not all areas are covered by 3G thus, if you entering an area without 3G, your phone is useless because there will be no signal.
if you set it to WCDMA/GSM auto, the phone will switch to GSM when there are no 3G signal available and that will ensure smooth phoneoperation in making/receiving call.
After a week of usage, I can confirm to you that I never have outgoing/incoMing call.problem and no data.problem.

morisa

Well so far my findings are null. i flashed kd2 stock with odin with the re-partition parameter on. Nothing happened. Was thinking re-partition would actually get rid of all the apps in case something there was giving problems... the phone was working fine when i was in england with kd1 stock... (How do i get rid of everything and start from scratch?? and what does the efs option do?? im tempted to use it xD) ... One other thing is i read somewhere that kd2 was giving trouble on orange uk (im ukthree but have tried with vodafone spain simcard) any ideas???
Efs is your IMEI code etc.
Backup as per post dev section .

iznee,
I have done a test regarding call in/out and also data connection. below are the test;
I am driving from KL to JB and crossing 5 states (KL, Selangor, N.Sembilan, Melaka and Johor). Along the 400km routes, I have taken the NorthSouth Highway, federal trunk road and also state road. My phone will change from H/3G to E/G when the signal is not available and I've no call drop whatsoever. I made calls while 3G/H signal is strong and also received calls. I did use the google maps.so that the data connection will be.continuous. In 3G/H mode, I can make/receive calls while the maps constantly refreshing based on my driving location.
when I enter the are without 3G, the phone automatically switched to GSM mode. albeit a bit slow.in data.connection, the maps still refresh without fail. when I make an outgoing call, the maps will stop refreshing as this is the behavior of GSM that voice call will take.charge and data will be suspended until I hangup the call then the data automatically resume its connection and the map refresh automatically showing my driving location. Then I use my other phone and call my SGS2 and as expected, the voice call going in and data suspended temporarily.
after hangup, data resume again and the map refresh automatically.
and when 3G signal is available, the phone automatically switch to 3G/H mode again and vice versa along the route.
all in all, I can say that my SGS2 works wonderfully and meets my expectation that phone function is priority. sattelite locks will take no.more than 10s and sometimes just under 2s. Superb performance by the phone.
Camera wise, no complain as I am.not a proffesional photographer. and I am more than happy for the camera performance.
Battery wise, no complain as I have unlimited data so i have all.my Facebook, twitter, push mail, livescore, news, weather etc ON 24hours. anyway, I have vehicle charger with me so the phone will be charged as long as I am driving.
this is from the about of the phone;
Android version: 2.3.3

Sorted!! I made a hard reset... Which led to a bootloop. Fixed turning phone off volume up+home+power . Clear everything and reboot... Voila now works like a charm hope this helps otgers in my situation
The Edge symbol in my Galaxy S2 disappears when the signal is down.
It never reappear when the network signal get back. Even If i change all settings... tried disable/enable "Use packet Data" and other settings...
NO USE! It seemed to be serious and consistent bug.
Hi balavj, maybe a silly question, but are you sure that you are in an area well covered by edge gprs signal?

Signal drops inside a room... when i come out of a room... network signal regains... everything works... data connection symbol does not come back... this is the exact problem... only after reboot... it resolves
Ah I see... Never met these conditions with my phone here, so sorry I can't be of much help.

i am having a similar problem, seems to have happened quite recently for me as previously i had no real issues with it at all.
I keep having to reboot my phone to get a mobile network connection, otherwise the Mobile Network Status shows as connecting all the time...
Very strange
Try other modem, or shove the phone into airplane mode and back again should kick it back onto data.
I have the same problem here...
Tried KE4 (Original), KG7 and KH3 modems e nothing..
Tried many roms too, and nothing, the problem is on all of them...
Data on/off, Airplane mode on/off, nothing gets data working back, only reboot...
Ps.: ROMs tested: Lite'ning, Cognition, Exynos, KE4, KG7.
Kernels: Niphetamine, Jeffrey, Speedmod
SAme here
same here...
Is anyone still experiencing this?
I was having major issues with connectivity, data and calls. I got to the point where i could barely make or receive a call or connect to a mobile data network.
I tried numerous modems and firmware, including original O2 carrier branded firmware, generic firmware and custome ROMs. I found the problem replicating across them all.
I finally settled on Crsikelos ROM (V14) with KE7 modem, however i had previously done a full wipe install of my original O2 firmware (XWKDE i think) and tried a couple of different modems (KH3, KE2 and KE7).
I even tried removing my SD card as i am convinced my sd card is not compatible and is causing issues...
All of a sudden everything started to work again?? I put my SD card back in and left it in, no chance everything was still working. So then i flashed Criskelos Rom and made sure my modem was KE7, that was about a week ago and it's still all good.
TBH i think it may be something to do with O2's network being pants (rather than my SD card )....
Not sure this will help but i thought i'd post my experience for you...
Hope you get it fixed
i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.
Hey Guys,
Ever since I switched from the original branded Three UK ROM, I've had basically no internet access at all on my phone.
Everything else works flawlessly, except I can't get internet connectivity.
I installed one of the "pre-rooted" roms from the forum a few days ago (unbranded UK Rom) and the issue still exists regardless of what APN settings I use or how I go about enabling/disabling the connection.
The phone simply dosen't show any kind of GPRS/3G signal on the status bar and only shows the standard phone signal with a little "R" above it. I've tried literally everything (going to the power menu, enabling/disabling data, etc). I've tried various APN settings posted on forums, but nothing works.
What else could cause this? The thing that is frustrating is that the internet previously worked on the phone.
Cheers,
David
Sounds to me like your phone is on national roaming..untick the box in mobile network settings, i to am on 3 uk and have never had any problems, are you 100% your apn`s are right ..let us know if you need check them with mine.
it does sound to me like we will have to step by step your settings to make sure there same as mine ie...know working.
Thanks for the reply lodger, where do you enable/disable national roaming on the phone?
Can you post all your settings so I can check against mine.
Thanks for the help

Hey everybody
I hope I can get some help from you guys.. I got this issue that I started to get into the running and started to need more of my gps to track my training and Ive noticed this weird behaviour of my gps.. It just wont even search for satellites whenever the 3g is on (you know the alert that says searching for gps).. installed the GPS checker to see if there was no satellites or something but it wont even search for them whenever I have the 3g on.. I found that the GPS works only if I disable the Mobile Data and restart my phone.. So I cant have both at the same time.. the minute I enable the 3g data it stops working and I have all the GPS options checked at the configuration and the wifi 3g assist.. What could be causing this?
Please let me know if some of you guys have some issue like this.. I have JellyBam 9.0.0 cyanogen mod based 10.1 and baseband XXXKI4

If you don't have this issue with a stock ROM, its probably a bug in the Jellybam ROM. Have you done a clean install? Since Jellybam has been banned from XDA, you probably won't get support for that ROM here. Maybe you should try contacting the dev of the ROM on their forum.

I tried the Omega stock V24 and had the exact same issue..
There's a number of GPS 'fixes' on here, I suggest you search for the threads containing those fixes & try some of them.
Hi!
I just want to share my workaround having same problem as this. After configuring my gps.conf as i've posted here: http://forum.xda-developers.com/showthread.php?t=1239713&page=77, all went smoothly and fast GPS lock for just about 5 - 15 sec, even on a cloudy or rainy day. Then last Tuesday morning, as soon as the mobile data got connected it cuts the GPS. In short, GPS & mobile data won't run simultaneously. I ran a series of reboot, shutdown, clean up... then as much as i don't want to, i ended up reflashing/reinstalling everything but to no avail! Now, since everything is fresh w/ my S2, but still had same problem. I now zeroed in the problem to how my mobile data connects. I didn't think of this before because everything works perfectly fine. Anyway, this time i changed the Network mode from "WCDMA only" to "GSM only". Finally! it works! problem solved.
So far as of this writing, both the GPS & mobile data connection are working simulteously. Only drawback are: (1) I can't browse the net using the "GSM only" mode because of the bandwidth limitation, but works ok w/ Waze app. (2) If i switched & connected to mobile data using "WCDMA only" mode, i need to switch again to "GSM only" mode & restart the phone in order for the GPS to works again.
I don't know, but i'm thinking if our telco here has something to do why I had this problem. Maybe they change some configuration... I dunno.

Hi,
I have exactly the same problem. Searching forum and the internet without results.
Last week I spent a lot of time with my SGS2. The problem occurs when gps and mobile internet data are used at the same time, but only when the phone use 3G or H+ standard.
When mobile data are transmitted on E/2G there is no problem at all. The issue with gps is that when I drive car and I'm in one location at the city (every day at the same place) the gps icon disappeared and no navigation at all. This is quite big square around 2x2 km. After I leave the area I have to turn off and on the phone and everything works ok, even when mobile data 3G/H+ are transmitted.
So described problem occurs only at the specific area. I don't know what cause the issue. After next researching I discovered, that gps disapeared ONLY WHEN THE PHONE USES UMTS 2100 MHz. In the service menu I mark only UMTS 900 MHz and the gps works very good. This time mobile data 3G/H+ are used simultaneusly with gps and everything is ok.
So the problem is olny when we are connected to BTS at 2100 MHz and only at the specific area. It seems that some kind of 2100 MHz signal intereferences wiht gps circuit maybe. I'm not a proffesionalist, I only suppose that.
Maybe somebody will find the complete solution with that.
My problem is at the cetral of Poland. I tried a lot of firmwares, modem drivers, gps.conf modifications. Nothing. Zero results.

Hmmm... it seems our telco here has something to do w/ my concern. Today, simultaneously my S2's GPS & 3G/H+ are working perfectly fine. I didn't do any reconfiguration w/ my S2, i just tried to switch how my mobile data connects, from "GSM only" to "WCDMA only".

Hi
I'm a first time poster here
I'm having a problem with the wifi on my s3. I've searched the forums but the problems see to be different.
I can install a rom and when it goes through the initial account setup. when i get to the wifi i see my home network strong signal. i tap it and put in the password and it disappears, leaving me with my network not in range. Which is strange because it's working fine on this laptop.
i did the power saving turn off via *#0011# - no luck
i've wiped and reinstalled numerous times. each time i can tap on my network before it vanishes
Please point me in the right direction

i've also used the cyanogen 10.1.3
one more try one more fail
Just tried android revolution rom. same problem
it picks up some networks, very low signal, but not the home router it is on top of. i can turn the wifi on and off and occasionally get a glimpse of my home network, but then it disappears.
really frustrating as i can't log into my google account and download contact info. makes the phone almost useless
Wipe phone flash your original stock rom or its update and test .
