[PROBLEM] Sgs2 data problem please help !! - Galaxy S II Q&A, Help & Troubleshooting

I'm currently in bahrain the problem and I'm using SGS2 for 3 months and I'm having this problem
the problem is when the phone in idle it will switch automatically to 3G and when I'm going to use it lets say I'm going to open WHATSAPP or CHATON it will connect to H or H+ if its available .. the problem is when its trying to change from 3G to H+ its not going to get data like the green arrow will get stuck and it will try to connect ... this problem happens only in the chat application like whatsapp + kik + chaton when i write anything its not going to deliver (not every time) but most of the time ..
i wiped the device .. i wiped everything .. i tried every single modem ! i tried many rooms .. i tried to change the CSC ... i disabled fast dormancy .. i disabled hsdpa with this code *#301279# to 3g only .. i changed the band using *#*#4636#*#* !!
i did everything i guess and I'm still having the same problem !!

I am with you on this one. Same problem, upload arrow stuck, no connection. Sometimes when this happen, I can use browser without problem, but no luck with application trying to use data. Sometimes it's just completely dead for both browser and applications. I am on STOCK KI3 ROM, KI3 MODEM. I had this issue from KF4 up. I also tried all the potential fixes, but still get this issue occasionally. When the 3G network got stuck, battery drain like hell. Maybe apps are in the loop of trying to get connection.

Any solution !?

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.

[Q] Unable to receive calls! <-- its a phone after all innit?

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.

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
Baseband: I9100XXKDJ

[Q] Data Connection bug. How to solve?

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

Whatsapp sometimes not working over wifi

So sometimes when I'm connected trough wifi my whatsapp won't send or receive messages. I then have to turn off my wifi , receive/send all messages and turn on wifi before it will work again. Does anyone have an idea?..

WHAT firmware and what version of whatsapp are you using?
Is your wifi kicking out a good signal?

I have the exact same thing, no matter what Rom, firmware, kernel, version of Whatsapp, router, modem, whatsoever. It sometimes just happens, no idea why.
When this happens I have a good signal. I'm on 2.3.6, and have the latest whatsapp version.

What did the Whatsapp developers say when you contacted them?
yeah these issues still exist... got it now on my device.
got I9100 on latest cm10 nightly (8th Sept.) with latest whatsapp version. and if you read all comments on the market you'll see that many ppl got these problems. sad
same issue here with i9300 stock ics
it works only on mobile data and when i turn the wifi on Whatsapp doesn't work
tired of deleting and reinstalling but same issue !!!
BTW my device is not rooted ..
i have been using what's app for good 4-5 months now and today i just got this issue. whats app won't work on wifi unless i turn it off and turn 4g on. i tried uninstalling and deleting the folder and did a clean install. it still won't work.
Just hit me last night
Got the same prob since last night!!!
tired to uninstall and reinstall it + boot my device million times and still won't work over wifi but my damn slow edge network!!
i have sent a email to whatsapp costumer's service and still waiting for their reply
These are issues related to the whatsapp Servers or sth. For me it works again. Without reinstall and so on. Just wait ... and tell them bout the problems
I've had this same problem for at least 6 months... doesn't work on WiFi but is fine on data...
What seems to happen is when you turn on WiFi it works fine for a while... but then stops getting or sending messages completely... just sometimes randomly it may start working again... say if you have lots of messages backed up to receive... at times it may start working again... but that means asking you people to bombard you with messages and still its not a sure shot solution...
Quite annoying I must say... especially considering reception is really bad in lots of areas and WiFi is the only way...
WIFI Whatsapp
Sort of same problem here, when i am on wifi and whatsapp and my phone is on there is no problem receive and send.
But when the phone is on standby after 10 to 15 min no more messages receiving, wifi is on.
when i turn the phone on and open whatsapp the messages pop in....
On data without wifi no problem.
WIFI setting always on.
Same problem buy not consistent. I have found a kind of fix, if your rom supports it, I use the long press back to force close function, then restart usually solves it. Alternately, pressing home, then swiping it off the task switcher sometimes helps too. Sometimes all you have to do is wait it out.
Was this problem solved in any of the updates. It appears as though I'm having this problem on one of my phones. It's the stock ROM with great wifi signal.
EDIT: I realize this is the S2 forum and my problem is an the optimus, but I am inclined to believe this is a whatsapp problem

The same problem started happening in the past couple of days. I a using CM 9.1. I enabled the Kill Application on long press of back button and you're right--After I did that and launched WhatsApp, the waiting messages (with the clock icon) went through and I got a check mark, then two.
Weird. All the other apps are working fine with Wi-Fi.
Same problem on my HTC sensation

I travel a lot and i was in India Last week and this week i am back in germany and it suddenly stopped working on saturday.
Any Solutions would be really appreciated.
Try this! Worked for me !!
I used VPN which worked for me . But i wanted a permanent solution. So I upgraded the modem firmware. Now it is working fine
Sorry to post here, but Im facing the same problem on my galaxy s5. I've tried a lot of things and nothing seems to fix it. I've changed my wifi router and the problem persists.
anyone came with a solution?
The problem is on the wifi router. I changue my router two days ago and i hadnt no problem with the old one.
If you retry to download pictures, it gonna works, but its really slow. Try to changue your wifi router to a newone
***********SOLUTION*****************
Guys,
I have also faced the same problem and here is the solution:
There is a Problem which started on 10th November. BSNL has blocked whatsapp.. BSNL users can not use whatsapp through wifi or dongle.
But there is a solution for this.. :
Install " vpn one click" or "Easy Surf VPN" app
Connect to India server
Or any country
Once ur done with this, u can use whatsapp and all the other sites blocked by BSNL
Enjoy Whatsapping

gtalk disconnection problem or Sweden 3 network apn?

Hi guys need a bit help with internet connection and gtalk. I know as far as I read that there are problems with disconnecting gtalk which might be the issue with correct apns. When I'm on wi fi everything works fine but when the phone is connected to network it's automatically disconnecting which is very annoying because I'm not getting all the messages.
My question is if anyone found a solution to solve this problem or maybe someone can share the apn settings for 3 sweden so that I can check if it's working. I'm on a stock 2.3.5 firmware + cf root.
Thanks

the rest of the apps work fine on 3g? if yes, then i believe the app might be the problem
if not the it must be the network, i would try with another modem or just call and ask them wth is going on
Thanks for a replay, actually I tried everything software related and nothing has helped. All apps work fine but thats not app related thing cause once I put the software from a scratch (wipe everything even internal memory and sd card) and it was the same. Today I started experimenting with apns and I see the progress.
Also as I am on 3 network dont know why the default setup is gsm\wcdma? As far as I know they don't provide gsm signal only 3g. Never mind every time I tried to change to wcdma only it was going back imidiatelly to previous state.
Just an hour ago I discover code to force the setup to run only wcdma and hopefuly that will solve my problem. We will see
Anyone from Sweden on 3 network has the same problem?

GPS not searching for satellite when mobile data is on

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".
