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.

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
Evertime I startup my phone with wifi on, the com.android.phone process crashes. I'm not able to connect to mobile network or enter my sim pin. If I boot the phone without wifi enabled, it boots normally. I've tried several factory resets, but the problem is still there. I've also tried changing simcard.
Anyone else with this problem, suggestions? I'm afraid I'll have to return it for repair/exchange.
Btw this is a XT910, european version.

Yup I sometimes have the same issue, but not all the time. I just normally reboot and its sorted. Bit of a pain but not a major issue to me and since I installed the update its not happened yet. UK unbranded handset
Sent from my XT910 using xda premium
update? is that the one mentioned in the dev forums? Any idea if its going to be pushed over the air or is it only available via manual update?
(sorry to hijack, I also get this issue but rather than rebooting I go into the mobile network settings and just get it to scan for cellular networks and it usually comes back)
Yep, the leaked OTA update for the GSM RAZR in the dev forums does fix this issue - at least, it has for me so far. Also fixed a bunch of others I had.
Sent from my Motorola RAZR
cool.. any idea when its coming officially?
Your guess is as good as mine. Didn't initially sit too well with me since we don't have a shipped ROM to flash back to, but I figure, when an official OTA does hit, we can just flash it over this one.
Sent from my Motorola RAZR
ok, no worries.. will wait patiently with fingers crossed .. Phone working ok apart from a few quirks and at least we know there's at least some update out there (which hopefully moto won't scrap)

Had the same issue. Restarting without the wifi solved the problem. Thanks for the tip. Looking forward for an official fix!
Try clear data of phone app. It should solve the issue. If not. Creat a back up then factory reset.
I wgot this problem when update the phone and this way help.
i have the same issue. if this message comes, it wont get any cell connectivity at all. i tried to turn on flight mode and turn it back off to see what happens. but if i turn it on. i cant turn it off anymore. i am stuck...i have to reboot

Tank you ianford10, rebooted with wifi off and it works well...
Hoping in a fast update, I turn off the phone quite often to reset it...
If you don't care much about your settings you can always do a full wipe. It worked in my case. Kind of painful but you'll get a working wifi. You can always use some backup software (ex. Titanium Backup) to save your texts, settings etc.
I have this too. But it coz I install MotoHomeFix.app. After I uninstal it, my razr back to normal.
I have searched Google but this problem seems to be unique to my sgs2.
I got my sgs2 from UK a week back. Its O2 branded with latest official firmware (2.3.3 and XXKE7), that's what see from phone info. I am using it on 2g network in Pakistan. The mobile works fine and connected to mobile network quickly after 1st boot. But after sometime, when i woke it up from sleep mode, it had lost mobile network connection and went to emergency calls only. This is continuing to happen everyday. I have noticed that it usually happens when the phone is turned on from prolonged sleep, esp in the morning when i wake it up. The network signals show full strength and it also searches all networks available but when i select my network it says , unable to connect try later. The only resolution is that i have to reboot the phone and it automatically selects the network. however that too doesn't work always and i have to reboot several time. Somebody suggested to kill Dialer and reconnect but it didn't help either.
Please help!!!

First update phone to newer version.
Second it might be a sim card problem. Especially if it is a very old card. Try with a newer card.
Report back.

Upgrade the firmware, but before this make a factory reset. If your phone is branded you can unbrand it if u want
KE7 is very old ( it was released like June) i remember i also had some problems with it, like random reboots and freezes hope it helps

JJE/Mario: Guys I have come back after a while since It took me longer to flash the ROM. I have updated it with XXKG5 ROM that I found on Intertech post, but to my astonishment, my problem remains the same. Phone stays on "emergency call only" after wake up or when I move few miles from my place. Sometimes it stays on this mode throughout the day. Strangely, GPRS/Edge works, however I do not see the 2 arrows radio symbol in notification area.
Is my phone damned or there is any hope?
Same problem..

that worked for me, but the problem had nothing to do with the imei number, if you look carefully. Also I think This is just temporary and it's going to revert back to emergency calls only. I'll let you know when that happens again
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)
Tried restarting, changing sim. Best I got was an Edge signal and it disappeared in less than a minute. I haven't noticed the problem since I'm on Wifi at home and in my office. Later I'll be going somewhere I expect with no Wifi so I tried it now, and voila I have no Mobile Data on my phone. I called the operator, my internet service is active on the system so I just had to try to restart which I already did.
So much for the "NEXT IS NOW" tagline. Seems that The latest Samsung phone is still operating on analog motherboard or something.
Quick update: I switched to WCDMA/GSM and now I have H+ when I tried LTE/WCDM/GSM, I get nothing. Is this because of the firmware I flashed?

I would have thought that if you are getting something with WCDMA/GSM, you'd at least get the same if your on LTE/WCDMA/GSM, as it should drop down to WCMDA/GSM in the absence of LTE.
However, if you have been flashing ROMs, I would suggest trying something else (perhaps stock for you carrier if carrier branded) before assuming the worst.
