Hi Everyone,
Sorry if there is already an answer for this on the Internet somewhere but I was not able to find it.
First the technical details about my phone:
- Not rooted
- Not updated (factory firmware)
- Phone version: GT-I9100
- Firmware versions:
PDA: I9100XWKI4Phone: I9100XXKI1CSC: I9100OXXKI2Build Time: Wed Sep 14 20:34:11 KST 2011- Baseband version: I9100XXKI1
- Android version: 2.3.4
- Kernel version: 2.6.35.7-I9100XKWKI4-CL575468 [email protected] #2
- Build number: GINGERBREAD.XWKI4
- Carrier: Vodafone Hungary
- Bought at: Vodafone Hungary
Problem:
Mobile network sometimes stops working and only a restart resolves it.
This happens 1-3 days after a restart again and a new restart resolves it again.
I realize it so that I'm not able to make outgoing calls, send SMS and others are also not able to call me.
What I see is that the phone tries to make the call like it would normally but there is no sound coming from the speakers and after some time it stops making the call.
When I try to send an SMS I just see on the message that it was failed to send it.
I also see that the GSM signal strength indicator is changing when I move my hand around the phone for example.
When I try to switch on data network mode it is not working, so I don't see the additional icon appearing on the status bar as usual and mobile network is not working either.
When I try to switch to flight mode (from the log press Power Button menu) the airplane icon appears, but I can't switch it off any more.
This means the flight mode button is not working, it is there, you can tap it, but it does not change it's state and when you tap it the menu does not disappear as usual.
The check-box in (Settings/Wireless and Network/Flight mode) is unchecked all the time, when you check it it displays "Disabling ..." for a while, but after this the check-box still remains unchecked.
So after you once switched on flight mode (when the phone is in the mentioned problematic state) it stays on until you restart the phone and switch it off again.
I bought this phone approximately half year before and this was working for at least 5 months.
It started to behave like this approximately one month before.
I don't remember installing anything or changing any settings lately what could cause this.
I'm not using a lot of apps, mostly Opera for browsing and sometimes Google maps and a few games.
I hope that is enough information and someone can help me or at least post me a link to some solution.
Sorry for not being clear on something.
Please let me know if you need some additional information.
Thanks in advance

Try flashing a new modem, these deal with network signal and such. Here is the link: http://forum.xda-developers.com/showthread.php?t=1131950
A suggested modem is KI4, which may work for a lot of people, but perhaps not you. This is when you will have to flash multiple modems to find the one you want. Worth a go.
P.S. This is what your CSC is, the modem. So at the moment, you have the KI2 modem, the one below the one I suggested. Just try multiple ones and see.

I just don't understand why it was working for five months and why it stopped working in the last month.
Do you think a factory reset or upgrading to ICS could help?

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;

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
Hi,
I posted this query in another forum, did not get any response so posting here too.
I have tried searching the www for this but not getting a good answer that will solve my problem. My samsung galaxy s2 has stock android gingerbread 2.3.3.
When I stay in a wifi network long enough and then I move out from a wifi network , 3G/data does not automatically enable. However long I wait, there is no 3G connectivity. HSPA/3G icon does appear sometimes but there is no "actual" connectivity. I have tried going to "flight mode" and back, tried disabling/enabling data network, nothing seems to work. Only a hard restart to the phone works and when it boots up next time, 3G/HSPA connectivity is just fine. And the problem repeats itself whenever I go back to a wifi network and come out.
I took my phone to customer care, they re-installed 2.3.3 and it seemed to work for sometime. However after a few days, I am back to square one. I tried the MMI *#9900# which disables 3g fast dormancy, did not help.
Any solutions ?

Flash 2.3.6 and latest baseband..tat wl help..

same problem here
Did you get your problem resolved? I have the exact problem. When i move away from wifi area i see the data connection indicator 3g or h, but there is no real data connectivity. Toggling data connection off and off seems to make it work again. I did a factory reset and updated to the latest firmware but still no help.
Well, Using Odin re-installed firmware I downloaded from android soul. It was a slightly different version: I9100XXKL1_I9100OXAKL1. And since it had a pit file I re-partitioned as well while using Odin. It worked well, but phone had frequent reboots.
Took to the service center; they initially claimed that is how it works on all galaxy s2 phones and is by design . After much detailed explaining, I told them to just load the latest firmware for the phone. I am currently on:

It's been a day and the wifi to 3g switch happens seamlessly. Let's hope it stays that way for good. Will update in a couple of days.
Hi, everyone.
After a slight fall, my S5830L started rebooting randomly. In some cases it just shutdown.
Looking for causes, I've found that when Data Connection is active ( In Settings - Wireless and Network Settings - Mobile Networks) it reboots.
If I turn off Data Connections everything is fine. I even can connect using WiFi when available, and synchronize accounts, send emails, access market, etc. All OK.
When I check again Data Connection option, sooner or later (rather sooner) it fails again.
Has anyone heard about issues like this? I need some help to deal with it. I can use almost everything, except data connection, and I really miss it
Thanks to all for the answers, any idea is welcome!
Augusto.
PS: Hope my mail is clear enough, since English is not my native language...

Hi, this is not normal, what firmware do have you installed?
This problem may be occur with any program installed and not for firmware problem.
I've flashed at least three different firmwares and with all the same problem persists.
Right now i've Android 2.3.6 (from Entel PCS, Chile)
Kernel: 2.6.35.7-perf- CL771662
Compilation Number: GINGERBREAD.UBKPL
Baseband Version: S5830LUBKPL
The problem started after my son dropped the phone downstairs, just a couple of steps, though...
I don't remember installed anything wierd, for that time.-
PS: I took the info about Entel PCS version from your web. Thanx. Nice Job!
I would have to agree that it sounds more software then hardware based. Usually if hardwares broken its very predictable. I would try to restore a different firmware stock or custom. I have an L and went with a custom rom. The data dropping might be a baseband issue but someone more wise than I would have to comment on that.
The wierd thing is that on the first connection it works, at some point the connection hangs, then while trying to reconnect it shutdown.
I was running a Samsung's 2.3.4 firmware when the problem started, then I flashed a Personal Stock 2.3.4 firmware (the original, that came with the phone), after that tried Entel PCS's 2.3.6. I keep this one because it's the newer version...
All behave the same way. The baseband should be the same for all, because the L (S5830L) is for LatinAmerica, and I've always double checked this.
Hi,
Have you tried to flash the original stock ROM again? You can download it from http://www.sammobile.com/firmware/
This site also explain how to use odin to flash the firmware.
My Android version is 2.3.4and Baseband is S5830LUBKPF and it works OK
I believe it might be hardware wise. Have you rooted you SGA already?
Hi there,
Just wanting to get some support with an issue I am currently having. I have recently rooted and flashed a custom ROM on my galaxy s2 but have come up against a problem. My data connection seems to be quite erratic. I am running the following specs:
Baseband: i9100XXLQ6
Kernel: 3.0.15-CM-g39df795 [email protected] #1
Slim Bean Version: 3.0.0 Official
Build Number: JZO54K
To be more specific. My data signal drops whenever the phones goes to sleep for an extended period. My signal bars remain full, however they are greyed out. I have read that this means I have no connection to Google Services. There is no other issue with data. It works fine with WiFi (no signal drops) and I can still call and receive texts.
Basically, I am new to all this flashing so any help/advice you can provide is great. I have used getRIL to ensure my RIL is the appropriate one for my modem version, everything seems to match there. Any other tricks or fixes I can try? Is it worth flashing a new modem?
Thanks

Just a little more information on this. IT doesn't actually seem like I lose connection during sleep as I still get email and facebook notifications. The loss of connection (blue signal bars to grey signal bars) happens for a couple of seconds when the phone gets unlocked. Is this normal behaviour? It only happens for 5 or so seconds and then the connection is re-established. I have checked and confirmed APNs, used getRIL, anything else worth trying/investigating?
I did not found the same problem so I decided to open this topic.
Some people have problem with wi-fi that does not connect, but my connects , however both, wi-fi and 3G, stop to hibernate.
I've been in advanced wi-fi and put "Keep wifi calling for suspension" in 3G went on "More Settings", "Network Furniture" and left marked until the "Data Roaming" hoping receive warnings of email, WhatsApp and others, but there's no way, when hibernated (suspended), stop everything. I did search for 3G network selected my provider because someone white that cold be the solution but nothing.
It worked fine with 4.0.3, which was update in the last year via wi-fi by Sangung, the problem started when I went to the Jelly 4.1.2 (Russian). I did following code on the keypad * 2767 * 3855 #,, wipes 2 times before applying the 4.1.2 with wipes after applied.
Then I thought: I'm going back to ICS. I did the wipes paranoid now 3 times, all of 4 wipes. And I applied the original 4.0.4 Brazil and nothing, when the phone suspends everything falls down, wi-fi and 3G. In other forun someone say the could be a matter of reinstalling the wi-fi card in cases of wi-fi does not connect, but here is also that for 3G, not the only wi-fi and when a try to conect its works better them before.
Well, with 4.0.4, then typed on the keyboard code * 2767 * 3855 #, I make 3 times in total paranoia the 4 existing wipes, and applied the 4.1.2 Spanish. And the same problem.
Do I have to edit some file on the device on hand to get the wi-fi always on when suspended?
To worried because it seems that nobody else have this problem.
I hope you can help me.
Phone bought with no contract with provider operator.

Thanks to all who can help.
I would like to thank all for the help, was now sending e-mail to the company that makes the program "Time Recording"
play.google.com / store / apps / details? id = com.dynamicg.timerecording
I was already to bring the device to Samsung and then I thought to install at least WhatsApp and this program on another cellphone that I have a B3000 .
And guess what happened to the B3000 (running Android 4.0)?
It start to tunrs off wifi and 3G when the screen turns off.
That was yesterday afternoon and i dont believed that I all excited already installed all the programs ever after upgrading.
Yesterday I came home and did all wipes and installed the 4.1.2 ...................... Spanish again.
So I spent the day with the system clean, and was connected to wi-fi service the whole day, I was installing programs gradually, this time testing, and I had no problem with wi-fi or 3G.
I received several program updates of Time Recording that I use about 8 or 10 months. and never gave trouble, must have been something in this installation at Play.
If they are going to fix I do not know.
If it's any hint, when someone has a problem after a FW Update, installing programs is going to slowly figure out what ta causing the problem, which was not the case of the poor Spanish Jujube 4.1.2.
Thank you all.
