I've recently moved to Hampshire, UK and got myself a Vodafone simcard. This problem probably existed already prior moving to UK but wasn't as noticeable as phone networks were a lot better in Finland and Czech Republic where I lived before. I often notice my signal being non existent or very low when other people with Vodafone but different phones have ok to good signal. I often also notice that according to the phone it has a HSDPA connection but no data is being transmitted, but immediately if it jumps to HSDPA+, data is being transmitted flawlessly again. I'm running the latest stable CM 10 on my phone. Additionally there seems to be similar issues with WIFI, other phones show good signal but mine doesn't.
Any ideas what could be the cause? Is the reception in S3 just worse than in my old Nokia E71 or Iphone5? What really puzzles me is the not working data connection with HSDPA, sometimes moving few meters might make it jump to HSDPA+ and data again transmits normally.
First go back to full stock rom, latest uk generic firmware and modem to test.
It's more likely to be due to your rom than hardware.
I've tried few different stock roms but the same problem seems to be present, still shows that I'm connected with HSDPA but no data is being transmitted. Any other ideas?
Check APN settings correct modem and CSC .
Would any of these affect the wifi aswell?

Modem, CSC and APN were all correct. My problems are with both wifi and phone network, could the problem be physical? Doesn't kernel come with the firmware, or should I try with another kernel?
You can flash a kernel or modem separately or as part of a whole firmware.
If you've tried going back to stock then hardware is the most probable cause.

Hey all, i thought i would start a thread about an issue that many canadians seem to have with the GS2, it seems to have been beat to death but there is no actual solution.
Im currently using the GS2 with Telus, its a wcdma/3G/H/H+ carrier using the frequency 1900 mostly and 850 at times on the cdma network, i used so far KG3-KG6 i placed them in that order because KG6 is the latest i tried and has proven to give me better coverage but its still really bad..
I can connect to data but only outdoors or only when the reception is full bars, if i start to lose any bars there goes my data connection and i can no longuer use any services data/sms/mms/calls i literaly cant do anything..
This is a big issue as i know for a fact that you dont need a data connection to send sms. but it seems the galaxy s2 under the current modem firmware im using KG6 wont allow me to unless im on full data coverage...
My question is this, what is the best modem firmware to use according to the frequencies that i meantioned earlier 1900/850 WCDMA i dont mind using another country's modem as long as they are oriented towards the same frequencies that i need
My phone came from Korea and i know they use 2100/900 could that be the issue? Is my hardware oriented towards that? At this point anything could help and please feel free to post thanks

Hmm, I'm a SGS2 owner on TELUS as well and haven't had any problems so far, besides the GPS Lock Time which most people seem to complain about. It takes about 1 minute for the GPS to lock for me, but my data is fine. No dropped calls or sms problems here. My download speed as I checked last was at 8.31 Mbps down and about 2 Mbps up.
But again, having horrible GPS issues. Wish I could figure that one out
Sobai can u post your results to *#1234#
so i can compare my settings to yours.
I'm using KG6 on Rogers network and don't have fantastic reception either. For most situations it holds calls -- but buildings with lots of concrete I lose the signal completely. It's as if I'm not truly on the 850 band ... my G1 had the same problem until I flashed a Bell-specific modem, that solved the problem. I guess we'll have to wait until Bell launches the G2 here, we'll be able to swipe the modem again.
i have an imported gs2 that i am using on rogers and it doesnt drop calls, but i have had times in the past when it would show 3g but not download any data. once i turned airplane mode on and off data would work fine again. the best radio for me has been the kf2 modem in terms of not having the data stalling issue. i find that even if i show no bars of strength i can still download data with no issue.
if you are on telus i would make sure so set the wireless settings to 3g only so the phone doesnt try to look for a 2g signal.
KG2 on a Bell SGS2 on Rogers/Fido network in Vancouver.
GPS locks in seconds. no dropped calls. H+ all the time, never once saw a 3G symbol. no data dropouts.
over 7Mbps down on this network with the SGS2, when i had 1/3rd the speeds an HTC Desire. great reception in my office downtown, my apartment, everywhere i've been so far.
KG2 (not the stock canadian though), in Montreal on the Virgin/Bell network. So far no complaints on the data. Since I started messing w/ the firmware however, the connection is on 3G when idle and only switches to H+ when actually in use. From what i've been reading many people have been noticing this when flashing over the stock Canadian firmware.
On the other hand however, the GPS has been having a hard time establishing a lock (whereas it used to be quite speedy and precise before I flashed). Won`t be able to test whether this is a firmware problem untill the stock Canadian is released by Samsung.

Wow guys I appreciate the feedback I thought I was the only one with this issue! I will definitely give kf2 a try right now and I'll also download the 3G only data app and give it a try and I'll get back to u guys with some feedback. Thanks again
Btw I'm using, touch x 3.2 rom that has kg5 on and I did notice a little improvement in the reception but the data connectivity is still very spotty so I'll give kf2 a try but so far kg5 modem is definitely the best one I seen so far to use on telus. Btw anyone trying to use the galaxy s2 on fido, I was never able to get 3G at all to work I was stuck on edge.

Do you know how I would be able to set it up so that it stays locked on 3G? I tried the *#301279# trick and disabling hsdpa and hsupa with revision 99 but to no avail. Even if it shows full bars and 3G I still get no data connection and also I can't send or receive texts unless there is a data connection for some reason, have you guys had this issue??

i have never needed to mess around with that menu. you should be able to go to
settings
wireless network
mobile networks
network mode
select wcdma only
that will lock it to 3 only. if you keep having issues you might get a new sim card from telus as that might be causing you some issues
Do you have your apn configured properly for your provider? If it isnt your data definitely work. Other then that I havent had these issues in edmonton on kg6 or maybe I just dont know what to expect reception wise. I do notice it hops from 3G to hspa to hspa+ a lot so i switched to only 3g. If anyone finds anything that improves that or reception though I would be interested

I wish there was a way to extract the modem.bin file from the bell sgs2 this way we could simply distibute it around. Someone should root their phone, install cwm4 and make a backup and we could simply pass the backup around so we could all have the modem

I had an issue with my s2. i was stuck at Menorca airport after an 8 hour delay. i spent the firs 30mins walking around the lobby looking for wifi and got nothing.
couple hours later sat next to someone with an iphone 3g and he mentioned he was glad of the free public wifi - free public wtf I said!
Sure as it was, he could find and connect to a lounge wifi. My s2 couldn't find a dam thing!!!
I checked my settings:
Wifi was on
Network notification was on
Use packet data was on
Data Roaming was off - As I don't want O2 to screw me over.
Could it simply be that the wifi signal wasn't strong enough to get the wifi? Eventhough the Iphone 3G had three bars where I was sat?
Could data roaming someone interfere with connecting to wifi abroad?
KH3 modem improved WiFi signal i find .

I'm on KF3...
Can I install one of the other variants of stock rom such as KH3?
If so I assume I need to CF-Root then overwrite with the variant stock rom/kernel I want?
And then CF-Root again the new variant stock rom/kernel?
Yes, the SGS2 has not-so-good wifi signal. Sometimes I can't get a full signal when I'm 2m away from the router. Nevertheless, I've found places where my phone was connected, and other devices couldn't, so it's not that bad. I'm also on KH3 modem.

Hi guys. Me and my wife both have gs2 and we both are on tata docomo 3G network. The speeds are good and this phone is awesome, specially for someone coming from a blackberry like me. However there is a peculiar problem both of us are facing. The data xonnection sometimes hangs on 3G and does not move to h or h+, and in 3g therd is no data transfer. The data transfer happens only on h+. That means for all practical purposes there is no data transfer. Sometimes it alsi so happens that the phone is showing the h+ icon but again there is no data transfer and i cannot access any internet related app. In these cases when the data hangs the only option is to activate the flight mode and then again reconnect. Then the data works fine. Off late this has started happening a lot. I have tried a couple of things like deactivating h and h+ and working only on 3g but to no avail. Can anyone help with this. I have not been able to test on other networks so i cannot be sure whether this is a device related problem or due to the network. Any help would be highly appreciated.
Regards

I am also facing this exact issue. I am on Airtel (India) network. For me, it seems to happen when I am at some particular locations, and works smooth at some other locations.
I just deactivate data network mode and re-activate it (long press power) instead of flight mode, takes only 10-15 seconds.
Don't know if rooting and using custom roms will fix this issue, because I strongly believe it to be network-related. I used to have similar problems with HTC Desire with various sense/AOSP custom roms.
He y buddy. But if ur on airtel and i am on tata docomo and we both r having the same problem, maybe it is not a network problem and is rwlayed ro some handset setting. Did u try the *#302179# trick. Did it work for u. Same problem in othe networks and for some of them this trick worked.

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.
Happening to me as well.
I always thought it was vodafone's poor network as my phone never downloads data when 3G is showing, it will only show upload arrow, then when it change's to H I get both uplaod and download arrows and starts working fine.
One thing I did notice though is when in Gran Canaria 3G was showing and working and data speed were ridiculously fast compared to here in the U.K
Surely this must be related to kernel used???
I have the same issue on my I9100 KI3, KF4, KG2 stock rom with either KG2, KF4, KI3 or KI4 modem. This is a combination of tower and our phone modem or kernel issue. I am having this issue with AT&T USA on KI3 and KI4 quite often in Champaign, IL. But when I went back to my country in Asia(Taiwan) 3 months ago, KI3 rom and modem have no 3G issue at all. I was on 3G 24/7 for 3 months without any issue there. However, I had the same 3G issue in Taiwan when I was on KF4 modem with KF4 rom when I first bought the phone. This is really a funny issue. I tried all the tricks and switching so many rom and modem, but 3g hang still happens to me with AT&T network. Now I am trying to lock the WCDMA band to 850 only, see whether it helps.
having the same issue here, but im quite sure its network related, inside my office the 3g dissapears at all and the same happends to a friend of mine who owns a SGS2 as well. whenever my outside the internet works as intended
also flashed trizillions of roms and modems before i gave up and blamed it on network rofl
I have an SGSII on Telstra running darkyrom XXLPQ with KH3 modem. I've got an issue where data works fine on H+, but whenever the phone drops back to 3G I get absolutely nothing. I've tried disabling fast dormancy etc, but that just seems to reduce how often it falls back. Is there a modem I can use or a tweak that will let it get data on 3G as well as h+?

I think you are better off on T-model modem, like DVKF2 by telstra as that will work on your I9100T model best.
I have the same problem on stock 2.3.4, xeu. But it just about never drops back to 3g in Melbourne. So haven't bothered with telstra modem yet.

I have a feeling you don't understand this very well and if I'm wrong I'm truly sorry. Either move to an area that you know does not have hspa coverage (otherwise known as 3g+ or 3.5g or h+ or 4G in North America depending on the phone model,manufacturer and provider) but rather only 3g and test there and come back to us or disable hspa in hidden settings (phone control/nas control/hspa control/choose r99 hspa off),which should disable hspa/hsdpa and hsupa and test and come back to us. That should give you data while 3g symbol is lit at reduced speed of course.
Right now all you seem to notice that when you engage data it is h+ and when it falls back to 3g, the symbol is only for voice over 3g therefore no data arrows.
Yeah, I'm talking about when I'm I'm an area that has poor hspa coverage and it drops back to 3g. Btw, my old xperia had no problem getting hspa in these same areas, so my radio performance is generally pretty bad with the sgs2.
Try all the I9100T modems until you find one that works well for you; they do generally work better with the I9100T than I9100 modems. And if that doesn't work, then you might as well try all the I9100 modems.
I've got an I9100T & found there's 2 or 3 I9100T specific modems that I get great signal strength/data speeds with (and granted 1 I9100 modem), and the rest are ordinary for me.
There is no simple fix for this. It's a trial and error thing. Unless you want to spend hours on the phone to your telco for probably zero result ?

Threw me off, because of mentioning 'fast dormancy'.
Good that I apologized in advance then.
I would still recommend testing it the second way I suggested just to see whether it works at all. I also sometime end up in an area that while seeming to have full strong signal, due to a congestion at a peak and other factors, has no or very little data throughoutput (this being in canada).
As suggested by others, testing other modems may help as well.
Don't even get me started with sgs2 and nokia's regarding radio.
Hi all,
Has anyone updated their Orange S3 to 4.1.2 through KIES? Does it include any bloatware or anything useful (unlikely).
Also, has anyone taken a dump of the FW?
Just wondering as I have not seen much coverage of this other than that it has been released, eventually.
Cheers

I think most people on here will have flashed the unbranded firmware to be honest.
Could be wrong though....

You are probably right, I am running the latest and greatest stock release, but live in hope that Orange will include Signal Boost in an update, one day.

I doubt EE will go to the trouble of a bespoke radio firmware for their network, the XXELLA modem is working fine for me on EE with 12Mbps speed recorded on occasion (why bother with 4G when H+ is delivering that?).
I'd suggest you try flashing a few of the 4.1.2 radio variants to see if your signal improves, but this may also decrease your battery life.

Orange Signal Boost is a UMA application for Orange -- it allows you to make/receive calls / SMS over wifi when you have no signal. It was in the GS2, but not in the GS3, unfortunately. I was really hoping it would come out as well as I have practically no signal where I live unless I am right next to a window.

Likewise, it is a shocking oversight that they have not brought this out for the S3. I have to stand in my kitchen if I want to use my phone! Sometimes that doesn't work either, so I have an excuse to go to the pub (I get signal there!).
Indeed
XXELLA does give good performance and I have tried modems galore, but when there are many houses between you and the base stations sometimes you just need some help!
On a slightly off topic note has anyone tried the BT Smartalk app? Although its just for outgoing calls its pretty handy for making calls against your BT allowance over WIFI.
If only we could have a seamless phone / wifi handover for calls.....I live in hope (and know that its been punted as a future before)
And I completely agree about the Signal Boost UMA side of things, its was super handy in my S2 when I occasionally ran a stock ROM or installed while rooted, plus I could make calls on the WIFI on the Underground in London, I do miss it!
