Hi, I've noticed that sometimes when I go into a weak signal area (buildings, underground, etc.) and the data drops off, whenever I go back to an area with a strong signal, the data symbol does not reappear and data does not work. Once I restart the phone, everything works fine. Not the biggest fuss, but if there's a fix for it, any help would be greatly appreciated.
what rom are you running?
what kernel are you running?
what modem are you running?
try toggling from airplane mode and then see if data comes back.
Sorry for the late reply, but the problem seems to be nonspecific to a ROM, kernel or modem. I've tried most of the 2.2 and 2.2.1 ROMs hanging around in the Dev forum, and I have been able to repeat the issue for all of them. Turning the phone to airplane mode and reverting does not work, it requires a full restart.
The problem may in fact be with my carrier, as I'm actually using the Vibrant in Canada on Mobilicity, which does not officially support the phone. However, I have not heard reports of the same issue. As I said, it is not overly major, but any more input would be appreciated.
I have the same problem in the past, first I changed sim card to my carrier because they said that that's the one causing the problem but that didn't helped at all.
So I try different modem, still no good. I stayed away from kb1 kernel and now I don't have that problem anymore.
You should try using a stock 2.1 rom or JI6 too.

I was just wondering if anyone has had trouble switching from 2G-to-3G and back? I'm on Orange and once I'm on 2G it won't budge to 3G or H.
I know the signal is there as when I force the phone into WCDMA only mode it picks up 3G but if that's not available it's obviously not able to switch back down.
Update: Okay, I've done both a soft and hard reset on the phone, switched it to WCDMA and back to Auto several times, pulled the battery out to do a few cold reboots, selected 'Orange' as my carrier manually and I'm STILL not picking up 3G after I've gone down to 2G. I don't really want to flash my phone via Odin as there's no guarantee it will work and I don't want to lose updates via Kies.
Any idea that to do?
Update 2: Just re-flashed using Odin as per the guide and it still doesn't work.
I really don't know what to do now
Update 3: After all of that it looks like it was bloody Orange's fault! There is a fault with the 3G in Bristol which is forcing people to use WCDMA only for now. Hopefully it'll all be fixed by tomorrow and I nabbed a fiver off 'em.
I Have Asked My Frnd About your problem! my frnd hasnt yet faced any problem !
There are extensive threads in this forum regarding 2g/3g switiching issues or connectivity issues..try and search it, maybe yours is having the same problem.

Oh not a-bloody-gain! They've already replaced my phone for another one and now I have to reflash?! I'm getting a little sick of this phone (or rather its software) now.

I've the same problem phone won't automatically switch to 3g unless i change it to WCDMA only. My last phone a i8910 would automatically switch to 3g for internet access if available the s2 doesn't......
Hi,
I've had my SGS2 now for around 2 months and thought it maybe be a firmware bug, but have recently upgraded to the latest via Kies which is KE4 and still notice from time to time that the my 3G just wont work.
If I try and access anything via 3G for example webpages you just get page cannot be found, but strangely enough what I have noticed the is H symbol will have a Green UP arrow active but nothing ever happens. In order for me to fix it I have to disable 3G via apndriod and then turn it back on again, as soon as this is done the 3G works as normal. Does anyone know of a fix for this?
I'm on the O2 network if that helps but I think its more than likely a bug with the firmware/phone.
Cheers in advance.
Davey
I've noticed it happen once or twice... but I just hold the power button, and then de-activate and then re-activate the connection from the popup menu. Sometimes when it has hung it can take a fair while to kill it after de-activating as well. But its literally only happened 2 or 3 times in the whole time I've had it; I've had catastrophic battery drainage more often which is a lot more annoying.
I've had the same issues on my phone aswell. I just got mine back from the repair shop and the problem still remains. The guys on the repairshop said it worked fine when they had it, but now its the same again. I dont know if it is my network operator who has problems with my phone staying online or what it is. But its damn annoying, I to have to disable / re-enable the 3G connection for it to start to work again.
I've yet to find a fix for this.. I'm on a network called OneCall, in Norway.
Any tips would be great
I had the same problem when I disabled fast dormancy.
Hello. Since about a week ago, I have this problem PERSISTENTLY. My phone is 3 months' old, I bought it new and unbranded from a store in town, and never rooted it. Only thing I did was upgrading the firmware through kies to the latest version available in my contry (KE7 if I'm not wrong). I have adroid version 2.3.3.
Well, I have found no solution to this problem that is absolutely unbearable.
I shall get rid of this phone as soon as I can because I am really annoyed by discovering problems after problems. I never had any iPhone, but I will try buying the iPhone 5 when it comes out. Hopefully it will work better. After all, it can't be so difficult to make a phone better than this one!
By the way:
I have 2 contracts with vodafone, one on this phone and.the other on a Nokia n95 8GB. Tried swapping the sim cards. Reault is that after the swap on the nokia there still are no problems whereas the SGS2 is still hanging on 3G and H.
So it isn't a problem of the operator, neither it is a problem of sim cards (also because they are different, one is 32k and the other is newer, and 128k).
Now, before throwing this absolute crap of a phone out of the window, I'd like to try a factory reset. But the question is: will I have to reinstall feom scatch every single app, after the reset? Is there a way to back up allbthe installed apps and easily reinstall them, without rooting the phone? I absolutely don't want to root the phone because I'm pretty sure I will end up selling it and so I don't want to loose the warranty.

Factory reset will mean you lost all data, everything on the phone that you dont backup.
But that might not fix it, your best bet is to try a newer modem, as its more a modem issue not a rom issue.
Thank you, veyka.
I just seem to habe found the solution! I disabled fast dormancy by dialing *#9900# (there's a hidden menu).
So far it's working great! It appears that my mobile network is not optimised for that protocol, therefore it must be disabled im.order to get proper internet connection.
So... anybody with this problem, try dialing *#9900# and tapping on "Disable fast dormancy" it is a fully reversible action (just in ca se...). Im fact, it cam be re-enabled at any time from the same hidde menu.
POST NOTE: No. This doesn't work. I spoke too soon...

This problem has been around for a while and I read somewhere that Samsung said they were working on a fix for it. I have had the problem from day 1 and it still does occur with Fast Dormancy disabled. I don't know if some of the newer Firmwares have fixed this or not. I am running official UK KF3 Firmware.
In fact, the fast dormancy trick worked only foe a short time. Now I'm back on wifi. What a disaster of a phone.
I talked to my network operator last night. They told me to go to settings->wireless and network->Mobile networks->Network operators and set it to manual, instead of automatic.
After this it seems like the problem wanished, but it might be just for now. Will test for a few days and come back to this!
Hey this is certainly a good suggestion! Maybe when signal is poor the phone starts searching for other networks and drops the connection. Good point indeed. I will make some trials as well.
Cheers
I got Atrix recently, unlocked and flash Allen #4 ROM, but when I use AT&T WI-FI in Starbuck or Mcdonalds, get message - "You are connected to the internet". But it works for a little while, then disconnect - "ATT Wifi Hot Spot" "Unable to confirm eligibility, please call Customer CARE..." but the WIFI is working very well in my DEFY...I'm using T-moble, someone told me have to transfer to ATT carrier...
Is this only one way to solve the issue? I'm in NY...thx for all ans
You could try different ROMS to see if its a phone or software issue or network issue. Have you used wifi that's not ATT wifi and tried that? It could be a network thing.

I have encountered the same issue. Work recently installed a few AT&T hotspots in our buildings. I called customer care, but they were not much help. Seems if I drop Wifi and re-enable Wifi I get a good connection without the message. I never have this issue when visiting a restaurant next to a FedEx store. Lately, this happens 50% of the time.
-Steve.
Thanks guys...I will try to flash official 4.5.91 SBF...then take a test
I have this issue on a stock ROM on my Galaxy SII Skyrocket. Problem is, it never works no matter how many times I turn wifi off and back on etc. Customer service is clueless.
-This device works fine on any NON ATT hot spot and my wifi at office and home.
-This problem only started about a week ago
-So far I have confirmed this is a problem in Sam's Clubs (2) and Barnes and Noble.
-All AT&T or non AT&T phones that do not have their stupid "Auto-Login" software work without a problem, even my tablet that is WiFi only. Same locations works fine as long as it's not a device with their Auto-Login software crapping things up.
rooted stock atrix on latest rom. same issue.
whatever......
Depending on the store, some have a log in in the browser you have to press a few buttons.

I did do that, but same problem. I'm new to the whole custom ROM thing, and I've noticed that even after doing what you said, it still has issues. Either it will connect, then disconnect, or put the phone into a reboot loop until I leave the area where the ATT wifi is. But, if I revert back to stock 2.3.6, I have no issues. Is there a fix for custom ROMs that I just haven't stumbled across yet?

I always do, but I have it on when I'm trying to use wifi, like when I'm sitting in McD's, I would like to use wifi. But I can't on a custom ROM. Is there a fix besides turning off my wifi when I want to use my wifi?
'Fraid not. CM ROMs are not endorsed by AT&T and so don't support AT&T pecularities. If you want support for AT&T hotspots, you're stuck with stock software or a ROM based on it, for example Nottachtrix or ICSROM or similar.

That's what I was afraid of. I've been trying with Atrics v1.0 and 2.0 with no luck on AT&T hotspots, always sends me into a constant reboot cycle until I leave the hotspot coverage area.
I have an unlocked unrooted S3 on Vodafone UK. This issue has been happening for the last few days whereby i have full 3G/H+ connection, but absolutely no data is working. No email, no websites loading, no whatsapp, nothing. The issue goes away as soon as I restart my phone, but then it comes back after a few hours.
Has anyone experienced this, and if so, how have you fixed it?
Go back to your network/phone provider .
Or flash different modem .

I am having this issue too. I may be wrong, but i realise this happens if i turn off my Wifi, the 3G will not want to connect to the 3G network.. Anyone else having such problem?
By the way mine is International version (Location: Singapore)
I'm having a similar problem where I have a good 3G/H/H+ connection but data seems to drop intermittently across all applications - I get the same sort of error message in browsers/facebook/twitter that you receive when you have no signal.
Anyone have anything similar and know of any fix?
I am not having such issue so far. I been updating my SGS3 using over-the-air update. I guess the MODEM has been updated as well.
Go to market and download "fast dormancy"(by gorkhanmoral) then disable it and reboot.
Check if your speed has improved,if it got worse then enable it again.
U need ROOT to use this tool.
I it didn't help, then flash a different modem
This is good modem
Cwm flashable

have you got any battery saving app like juice defender installed in your phone?
Is mobile data working at all? or is it constantly "uploading" but never "downloading" (up arrow lights but not down).
If what I just described is your issue then this is a network issue relating to android in general.
Basically your phone will be connected to two radio towers and gets confused as to which one it should use, rebooting or flight mode may help force it onto one tower or you may have to speak to your carriers "high network technical team" or whatever they are called for you to get them to force it onto one tower.
I had this issue on the HTC hero (a long time ago now) and it took 9 months for Orange UK to work out what was going on.

Congrats. Orange Luxembourg (my gf's network provider) still hasn't got a clue.. But they seem rather clueless about everything except writing invoices.
Flashing an Asian modem on her S2 made the issue far less prominent since they seem not to get confused by antenna ping-pong. (Tango Luxembourg, my carrier, has this issue too in the main city)
I have a weird issue with the phone- I have not decided yet if its problem with hardware or software.
At the first step, without change nothing, Suddenly a sharp drop at signal strength began. few days after, my phone stop connect to network at all. In the "operator select" screen, my operator appear but I get error "selected network unavailable".
I tried factory reset without succes. The only thing that worked was sbf to stock- but the signal still low and again, after few days, the connection lost.
I'm using gsm in israel- Already tried many rom's, so can't use warranty.
Maybe there something I can try before I give up?
Do you have better signal with some other phone?
Try another simcard.
Did you flash any radio as you wanted to do some days ago? Not all the SBFs change your radio, and maybe a bad radio is installed on your phone.
בבקשה ממך אל תענה לי בשבת. כניסת שבת בשבע ודקה ויציאת שבת בשמונה.
I asked about the other radio because this problem, but I didn't got a sure answer so I left the idea. I tried other sim but the problem didn't gone. And others phones works well at same place where the Photon doesn't. I ordered new sim from different operator- I will report after.
In case I want flash radio without full sbf, is it possible? Can I save my data without all the backups methods?

You can try KKDI radio here.
There are also 2 radios listed here, but ask someone with experience (like peetr_) before you try one of them. If you flash one, make sure it's the one for your build.
שבוע טוב!
