Loosing Data connection - Galaxy S III Q&A, Help & Troubleshooting

Hi All.
Provider: "3" Austria
ROM: Omega V32 & Android Revolution HD 9.0.0 (or earlier)
When the Phone is lost the Network connection (elevator, no coverage,...), it reconnects, everything seems to be fine, it shows also 3G or H+ data connection, but that's not true, what's displayed on screen, phone calls are possible, but there is no data connection available.
Restarting the phone and everything is fine. Switching off( on FlightMode or data won't help.
Now I installed just for testing CM10 nighly and it work's fine, no problems!! BTW, it worked also fine with Omega ICS Versions!
I like Omega or Revolution muc more then CM10, cause I like TouchWiz. Do you have any ideas, how to fix this? Maybe a different kernel?
THANKS for your help

u could try a different modem

Thanks für the hint... it's hard to find a summary of relating Modem's or Kernels to trie.
I did a full wipe now and installed everything from scratch, also using the latest Omega V26 Rom. It's a bit better now. The difference is, if it's loosing 3G, connecting to GSM it hardly reconnects to 3G, and if it's done, no most of the time HSDPA is not shown. It's not really reproducable, cause it depends on the location. Switch off / on data solves the problem.
I read somewhere here, that I'm not the only one with problems related the Austrian Provider "3". Anyone else here?
Maybe someone here has a list of Kernels and Modems to use or a link, where to find. I used Search but toooo many results for me to find the correct on.
Thanks

[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?
Sent from my GT-I9100 using XDA App
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.
Sent from my GT-I9100 using XDA App
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.

[Q] 3G / HSDPA Not working after flashing

Hi guys,
Having some difficulties here.
Searched on the forum but didn't find a proper way to fix this.
I installed Villainrom 3.0 with the ninphetamine 2.0.5 on it. (already did it 3 times, with cache wipe and dalvik)
After that, my data connection doesn't work anymore.
I have the right APN settings, and tried other modems and kernels.
These are the ones that I tried:
Modems: XXKE7
XXKE4
KE7
KH3
KI2
KI3
Kernels: XWKE2 (was the standard root)
ninphetamine 2.1.3
2.0.5
I'm really stuck here
Please comment.
Thanks!

No, my girlfriend her phone/3g works fine, with the same telco
Do you get a data connection on the stock rom?
I would usually put this down to the provider.
Sometimes its because your efs folder got corrupt (no imei) or wrong radio/modem. but as you have tried so many im pretty sure its not that.

I did a backup to my stock rom, but kept my ninphetamine 2.0.5 kernel.
The data con. works with the stock rom.
I'll try again tonight, maybe I should play with the APN settings a bit.
If this doesn't work, I'll just leave it with a stock rom
Maybe your phone/telco doesn't like this firmware version.
Try another custom rom with different firmware.

Write down all the apn settings and apply them to villain, I cant see why that wouldnt work.
Same problem here, IMEI ok. Also tried different modems.
Btw, 3G works, but not HSDPA. Sometimes H/H+ appers for a brief period of time and goes back to 3G. Same SIM on another phone gives me constant H/H+ icon.

Nobody facing similar issues?
UPDATE: OpenSignal says that the connection is HSDPA (sometimes UMTS), but the icon stays "3G".
I'm having the exact same issue. I got it back last week by repeatedly switching between Gsm only ans auto but that's not working this time. Talk mobile UK. I'm going to try Cyanogenmod. Shame as I really liked Villainrom.
Edit:
Re-entered the APN settings and it's all good now.

Well i've investigated this a little bit further, and found out this only happens when using a WCDMA 2100 network. I've tried another carrier (WCDMA 850) and it stays locked on HSUPA all the time. I i only knew why HSUPA works on my original carrier only while on a call...

Data Connection not working anymore after flashing

Hey guys i got a problem.
After flashing my phone normally with Odin like usual all of a sudden data connection aint working anymore. I works fine with wifi, but not without.
It shows 3G/H signal in the status bar, and i see the upload arrow is blinking so it is sending data, but not receiving anything.
I tried googling it, tried flashing various different roms that worked before and original firmware, but nothing helps so far.
I checked the provider info in the phone, and its all correct.
Kinda lost here, hope someone has an idea how to fix it
thx in advance
nobody? i tried everything so far and dont even know why its not working anymore
It's going to be difficult to get much help here because I don.t think most developers have had time yet to get into the innards of the A501. Have you tried flashing back to the original stock ROM? You did back it up before you flashed it with a custom one right?
Sent from my A500 using xda premium
No nandroid backup, only titanium backup since i never had problems before.
I tried flashing all kind of original firmware now, KH1-3, even older ones, the latest. tried all custom roms that worked fine before.
Tried different sim cards, readded the APN settings etc.
Found out now that 2G is working, but as soon as i switch to 3G etc it shows the signal for that, i see upload but no download, so it basicly stops working.

(Instead of quick reply, i hit thanks first!)
Dial *#301279#. If it doesn't work, dial *#*#301279#*#*
Select 2nd option (Change HSPA revision or whatever).
Then select 3rd option (Release 6).
Restart.
Also, check your APN settings.
Use an app called Tweakker which will configure your apn if u dont know exact settings.
thanks for the quick replies guys.
so i did play with the codes today already, the option you stated i tried but sadly it didnt change anything.
HOWEVER i did choose disable HDSPA completly now, so i am on 3G only and guess what, now it works!!
Speeds are not what they used to be at this location, but that might be due to my data limit so i have to check.
With other codes i found out that while being on H/H+ phone didnt download 1 byte, so i have to wonder why.
With 3G it is working now, but what could the cause be. Used to flash quite often and it always worked, so not sure if thats even related to my problem atm.
Any idea what might cause the H stuff not working at all? I read about the SII getting stuck on H+ etc. before, but all the tricks with rebooting or toggling flight mode etc. didnt work for me
so far, thanks a lot!
Try different modems. Depending on ur location and service provider, atleast one should work right. I'm using KI3 modem without problems.

modem depending on location and provider?
i tried several modems from the original firmware thread under development. they all used to work fine before, now they dont. KI3, KI8, KH3 etc. all nothing :/
Hmm strange. May be you should delete all apns, and configure a new one for your provider.
Also give KG5 and KG2 a try.
i am having a SGS2 with KI3 and sensation rom 1.7 with kernel siyah 2.0. after doing this i am also facing a problem with my data connection. it works but its on / off.
can you suggest come remedies like now please .............

[Q] Needing help with S5830L

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?

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.
My phone:
SGS2
Android 4.1.2
3.12.0-rc1 Siyah-Dorimanx-V8.41
XWMS3 NeatROM v6.3
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".
