I have read somewhere that some people are experiencing their data connection to freeze or have idle times even with good reception.
Now I have never had an Aussie firmware, in particular the modem part of the firmware which I believe is the part related to the phone performance?????
I have tried disabling and enabling the fast dormancy. Turning off data and enabling it again fixes the problem. The hang isn't permanent so things like email, syncing, weather all update fine, its just web pages can sit loading for ages or time out with no acitivity shown. But try again a few minutes later and the internet is super quick without the reception of tower changing.
Does anyone else with Optus Australia, or vodafone or telstra for that matter, have the data stalling issue? What exact modem version are you using?
Yeah i think this is actually related to Optus's network.
I have scrubbed my phone and applied the XXKH3 firmware and it seems a bit better to me. I also disabled Fast Dormancy.

I have too agree with Simmo3D the current state of not just optus is abysmal.
But there is a light at the end of the tunnel with the NBN it should is ease the congestion that we have been having to deal with because of the explosion of people updateing there facebook status.
Also we have both telstra and vodafone putting in new 850MHZ tower which can handle a much larger amount of traffic which means the Que time or "Idle time" will be reduced.
I had wondered about it being Optus... but turning data off and back on straight away seems to fix it instantly so wondering whether it isn't because of congestion otherwise it wouldn't always fix the problem temporarily .... but I am no expert. It isn't a slow down, its a complete stop with no data going either way. Occasionally it will sit there sending permanently but that isn't always the case when it stalls.
I am not disagreeing just trying to confirm whether this is definately optus or something else related ot the wrong modem component for optus network.
I never noticed this on my previous phone (i8000 on win mo and alos a buggy android port) but to be honest I didn't really play around on the net so much because I didn't have anywhere near this amount of data I have now and it wasn't as appealing to play round with online....
Were either of you on Optus with another phone you used data on a lot? Did that experience the same stalling of data.
no problems on telstra here
My dad is optus and has the same issue on his phone. Me and my gf are on Vodafone and have a slight issue but not as bad becuase were mainly on the new network. Telstra finally turned on QoS so there is no problem on that network.
Remember there are 800 open cases with the ombudsman over optus's delivery of service.
There are tweaks to the build.prop file to mitigate phone issues but won't help as much as if optus fixed there infrastructure

Thanks all. Looks like concensus says optus is the main culprit and i don't need to head down the flashing of a typical optus modem firmware with my imported phone to fix these dramas. Thankfully its not all the time so I can live with the slight frustrations at times. At least the voice calls aren't doing the same thing...

As far as I know there is a known bug in the phones software that stalls data transfers when switching between 3g and h. The fix is to lock the phones data out of h.
To do this use the stock phone dialpad and key in *#301279#
Select option 2
Select option 1
Then use menu key and go right back or end.
Should not be using h network now and your stalling should be fixed.

This thread is about the famous 'data hanging' problem experience on SGS2's and how to address it on the Three Network in the UK. (Where the green arrow gets stuck on uploading with no download).
The problem from what I understand is that the handset constantly changes between GPRS, 3G, H and H+ to save power. Fast Dormancy is a setting the SGS2 uses to make this even more frequent.
The Three network is pretty flaky, and relies on 'borrowing' signal from other providers. This means EVEN MORE changes. The SGS2 doesn't deal with changes particularly well and due to the sheer number, often gets stuck when a new connection is formed. Cycling data connection will fix the problem temporarily
I get this problem with stock firmware a little and custom firmware a lot.
I do not want to be stuck on KE4 forever and I do not want Three's stupid games installed. I am very annoyed.
Update 19 August 2011
I spoke to Three today. I explained what happened and both the first line rep and his manager knew the problem that I have. They acknowledged that it is an issue that they are in talks with Samsung about trying to fix.
They told me that I can have an exchange, but that EVERY SINGLE ANDROID PHONE ON THEIR NETWORK has this problem.
However they still refused to give me a refund as I'm (well) out of my 14 day cooling off. I told the guy that under the Sale of Goods Act, if something doesn't do what it says on the box I can get a refund for an indefinite 'reasonable' amount of time.
I am getting a call back from his superior this week. Will report on progress, but this is big. Three are selling phones that they know don't work properly on a mass scale. I am going to use this to my advantage.
I bought mine sim free. Was on t mobile for a while and moved the 3 a couple of weeks ago. I've not noticed any problems as you've described. I once had this on O2 though and it turned out to be a localised network fault.
Are you using juicedefender? JD caused that same problem with my old Milestone, but so far it's fine on SGS2 on Three.

Hi guys. I have this phone on Three here in the UK and annoyingly, several times a day, the data stops working. It gets stuck with the uploading arrow in the bar (no download) and will just sit there.
Cycling the radio / flight mode brings it back to life for a few hours. Does anyone else on Three experience this? I need to know if mine is a faulty handset, or if its a network problem.
This happens regardless of which ROM I use.

Mike, mine is exactly the same. It will absolutely fly for most of the day (even sometimes days at a time) and then it will just get stuck. Press and hold power to deactivate, and reactivate 'data network mode' and is well again till next time.
Seems to happen more when the phone has been sleeping for a prolonged time but not always the case. Doesn't appear to be any pattern. Changing ROM makes no difference here and I've quadruple checked my APN settings.

Known issue.Is not carrier dependent.Same here with Vodafone Greece.Some guys told that is hardware fault and some software.I think is software problem

It is the modem firmware. Once I updated to kf2 modem the problem dissapeared.

This happens to me most days, I have been rebooting to get back online. I will try the flight mode on and off to see if that helps.
But this is obviously a problem with Three network. I just thought it was Three`s sneaky way of throttling my "as much as you can eat" data plan.
I have KF2 modem and the issue continues.
I am glad to hear that others face the same problem. Is anyone in the UK on another network experienceing it? My friend is on Vodafone and we have the same ROM. He does not experience the issue at all.
Does anyone have a link to a thread which documents this issue?
I rely on Whatsapp and Email for communication, and this stops both from working. I might actually have to send my SGSII back if it continues
I'm on Three UK and have not experienced this problem yet. Shall let you know if/when I do.

Ive definately had this recently. didnt have it b4 though.
I have this problem. Stops my LiveProfile from working properly. Its very random too.
Can be quite annoying.
Hopefully it's a software problem rather than hardware. Only time and updates will tell.
I'm on o2 network with stock KE7 XEU firmware.
Same as op. Three and on ke7
Just went to kf2.
Will see what happens
If anyone manages to fix this, please share.
Incidentally, my bluetooth does a very similar thing with my car stereo. It just freezes and requires cycling off and back on.
I'm on three and get the same issue.
I also do the flight mode recycle.
I'm also using juice defender.
It's not a major issue for me more of an annoyance

I just remembered something you can try. Change the APN from ( i think) three.co.uk to just 3INTERNET.

So far, this appears to be working!
(although I can no longer check my usage on the Three mobile website, but that's not too much of an issue)
I'll keep this thread updated with my progress.
Incidentally, I did not get this issue until I started flashing ROMs - or at least I didn't notice it.
I've been having this issue the past few nights on Orange. Fine during the day but at night the data stops.
Reboot the phone and it comes back. Just about to try KF2 modem to see if that helps.
yeh i have the same problem.... i can be going on internet browsing away then 4-5 pages in it just stops... and takes 1-2mins load and then just stops all together.
i dunno why its doing it...
im gonna call THREE in the morning ask what the hell going on.
also the H is soooooooo slow
3G when working is ok speed, but omg H is slow as

Please do let them know that a number of us are experiencing this. Although it doesn't seem limited to THREE, it definitely isn't on every handset.
Mine still hasn't done it since I changed APN as recommended above though.
SO, I've been using the Galaxy S III International Version here in Kelowna British Columbia since June 3rd. I've tried the stock radio that it came with (XXLE8) but noticed I get better signal with DDLE9, however I still noticed that my H+ signal changes to H and the data just hangs for a good 10 seconds and comes back to normal. However my data transfer rate is spot on when the freeze doesn't happen.
I had a similar issue with my Galaxy S II last year when I first bought it, and found that it was completely fixed after flashing a new ROM and new Radio.
I'm just wondering if anyone else seems to be having this issue as well with data freezing for a few seconds (in Canada) and if you've found a way to fix the issue you might have been having. I've also disabled Fast Dormancy as my provider claims they don't use it.
Thank you!
141 views but no replies? Is no one else having similar issues?
That might be due to the device trying to switch antenna and something going wrong. Are you moving while the issue appears or in an area with poor network signal? Does the issue _always_ appear regardless of location or only in a certain place?
Try installing the app 'Network Signal Info' and check if the CID and/or signal strength shows any changes during the 'data freeze'.

I used the guide from this post http://forum.xda-developers.com/showthread.php?t=1731132
Ok, here's a challenge.
I am a uk t-mobile subscriber. In the uk t-mobile and orange merged their cell networks into one big network (tmob bought out orange) with the original t-mobile cells still showing up as "t-mobile" and the now merged orange cells showing up as "t-mobile orange". Tmobile offered their subs the option to also connect via orange cells and orange the same to their subs.
At the time i thought this was a good idea. More cells, more signal in more areas, better experience.
I was very wrong.
Basically the orange cells are absolute crud compared to any of the tmobile cells. You notice a massive drop in bandwidth between a tmobile cell and an orange cell and i wish i had never opted to use both.
So, i am looking for a method to allow me to block the switching to the orange cells so i can stay on my native (faster) tmobile cells all the time and never ever have the phone connect to an orange cell ever.
Any ideas?
I know each network has a numerical value that denotes it so there must be some way to tell the baseband never to switch to this particular network right?
Any advice anyone can give would be greatly appreciated. Cheers.

I was looking for the same solution and came accross your post, judging by the lack of replies theres still nothing to sort this out. Annoying when Orange forces to take over and is usually a weaker signal!

Dont know if that dev would have more knowledge .

I thought you could manually select the network? TMo and Orange come up separately as an option there?

I'm also looking for something so I can select a mast... the closest mast to my home is only 2.5mbit while a mast just a few miles away is HSPA+ and peaks at over 10mbit.. when my local mast was down I was able to connect to the HSPA+ one and have full bars... there must be a way of telling the phone to ignore a mast?
You can manually select the network in network settings however the phone freaks out then whenever there is no signal instead of quietly waiting for new signal.
This sort of solves the problem but creates the additional annoyance of notifications of no signal.
I couldnt find any way of blocking individual masts. Im not sure it can even be done on the user end.

Hi All,
I am having a strange problem with my S2 since last few months. I am from Mumbai, India and using Airtel network. There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while. It happens that whenever I take my cell in that area, it starts losing signal bars till no bars are highlighted on the status bar at the top. It keeps showing zero bars but does not show "no signal" icon. Then, after keeping my cell in that spot for a while when I bring it in a better connectivity spot, signal bars start increasing and it appears that my cell has better reception again. However, if anyone tries to call me or I try to call anyone, they get "Out of coverage area" message or I get "Network registration failed" message respectively. I am having this problem since the day I started using Airtel and have tried a lot of remedies but only thing that works is rebooting my cell. I have tried using OpenSignal app to reset my connection whenever my cell comes back from the spot but even that fails to revive it and ultimately I have to reboot.
Has anyone faced such an issue and any ideas about a fix? Does it look like an issue with my cell or could it be an issue with my network provider? I would prefer not to root my S2 since I have 3 years warranty on it but if you think that it's the only way out of this, please let me know your opinion.
Thanks.
Sounds like a carrier issue to me. You pretty much said exactly that yourself when you said 'There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while'.
That's normal in many buildings. Particularly if the network coverage in your area is borderline or poor. I have a similar issue in my house, in a few rooms I get no bars & sometimes coverage drops out completely, whereas in my loungeroom/dining/kitchen at the back of the house I get good coverage (for me, anyways).
You could try different modems, which might improve things. You don't have to be rooted to flash these, you can flash them using Odin. Tho it is easier to flash them with CWM if you're rooted.
I use to had the same issue with my 3 carrier at my desk in the office, and still on 2g services. I but since last month they already improved to hsdpa network added more bts and now my blank spot became H.
Yes you may try to change other service providers
Sent from my GT-I9100 using xda premium
Thanks for your suggestions guys. Yes, it might be only related to the carrier. But, I think that if signal goes down to zero and then when my cell is back in better coverage zone, shouldn't the modem take care of network registration by itself? My problem is that it doesn't. I have to reboot my cell every time after I come to know that my cell is showing signal bars but is not actually registered on the network. If I reboot my cell, everything becomes normal and so if it was just an issue with the carrier, shouldn't it continue like that even after reboot? If I think about it logically, I think following should help me out:
1. Try out a different cell for a few days and see if I face this issue or not.
2. If answer to 1 is no, then try out different modems on my S2 and see if that helps.
Actually, I just wanted to check if anyone else has faced this issue and figured out that something is not right with S2 drivers or something? That would help me with quick resolution of my problem.
Sent from my GT-I9100 using XDA
Yep, your logic is sound ;-)
One thing tho. With regard to trying your sim out in another phone, you have to keep in mind the radio hardware is obviously different in different phones. And what that means is (and this is something I've observed on XDA), chances are you'll find the sim works perfectly in the other phone & you have no issues at all. This might be due to the actual equipment your carrier is using in the cell tower(s) you're close to, also the frequencies that gear is using might also be playing a part in your problems.
So definitely try it out in another phone & see what happens, but you could do worse than try out a bunch of modems in the S2 & see if that improves things.

Those are carrier issues, and maybe even the material of the constructions, in my house there are rooms where there's almost no signal at all, and in the living room it's ok, you should try to see in which tower you are connected maybe thats the problem
I have also had these problems on various networks here in Australia. If you don't need the data network, you could try using 2G only option. But that's not really a fix, is it? I suggest you try a pre-paid SIM from another network provider, to test them out first, before re-contracting.
Good luck. :fingers-crossed:

Yes, I was also thinking about it. It could be the combo of cell tower and S2 that are not liking each other that well.. And, if that's the case, I really hope that the issue can be resolved by switching modem drivers. I will have to do some what-ifings to nail this down now.
I like the other suggestion by HotrodHarry on trying out 2G only option - not the best way out but will help me in zeroing down on the cause.
I have an I9300 which I use on Vodafone UK. The phone was a sim-free handset, CSC=BTU
I'm currently running firmware XXEMC2, rooted
I sometimes get an issue where my HSPA data connection will stall. All I'll see is the "up" arrow flashing for around 2 minutes, but no data will be downloaded.
After around this period of time, or if I switch phone off/on line the connection will start working again
A few times I've noticed when this occurs the data connection symbols will disappear completely - so perhaps the phone or network is totally timing out.
This has occurred with a variety of firmware levels back to XELLA and before. My suspicion is that it's a network issue, but was wondering if anyone sees this on any other network.
I am considering trying one of the vodafone branded firmware's MODEMs in case there's anything they tweak that might work better.

I've now tried a variety of modems (including vodafone fw / modem) & full firmware but continue to see this issue from time to time.
If left alone after something like up to 5 minutes the connection will drop and recycle. No idea if that's phone or network initiated.
It is however VERY frustrating. My strong suspicion is that this is a VODAFONE NETWORK ISSUE not a handset issue. Of course as my phone is a sim free phone it may be tricky convincing vodafone of this fact.
Has anyone else seen these issues, especially on vodafone uk?
It *seems* to occur more on a few particular cells (well I notice the ones at gym for example) and less (possibly never) on suresignal, and just occasionally at work (small cell?) Overload on the cells is my suspicion ... classic vodafone.
I've never noticed this on 3UK, though that's been on a nexus S (currently lost ). If only 3UK had coverage at work I'd switch back easily. Vodafone has broader geographic coverage but I'm convinced the network is more flakey
When you have an UP arrow, that is upload. This signifies a connection going out from your phone to the network. If this hangs for a while and does not produce any connection back (DOWN arrow), this would definitely signify a network issue to me. Sometimes on the S3, the signal bars say there is a signal when there isn't or there is a signal but the connectivity between you and the network is non-existent
There are several things that can cause this. It can be Mast, Network, SIM, Modem, baseband... Its hard to say. All you can do is rule them out one at a time.
My gut feel is network too. It's definately happening with a good decent signal when stationary.I need to check more closely but it also seems location dependent (but not single location)
