[Q] Data connection and other 3G problems.. - Galaxy S II General

Hi to all SGS2 fans out there
I'm a happy user of SGS2 but I noticed some problems during WCDMA usage. After few minutes of using 3G/HSDPA connection is still looking good on the signal bars but I'm unable to open any webpages/android market etc. I have to disable and re-enable data connection in settings to get it back working... for another couple of minutes..
Secondly I have short breakups during calls. When I'm talking to someone the phone mutes for a second. It doesn't happen every time - but it's quite often.
I'm currently using Lightning ROM 1.5 - but I had the same issues on 1.4, 1.2.
When I'm using GSM only - everything is fine.
Do you think I have a faulty unit?

I'm getting a similar issue. Currently on VillainRom 1.4. Full 3g bars but cant use browser, market, etc.

hi,i have just sign to forum now,i was looking around and seems like very populer here.
Anyway i have same problem here plus when i have 3G or HSDPA on my bar it is changing every few seconds (for example a few seconds staying 3G and a few seconds staying on HSDPA,not stable and non stop) and seems no stable and killing battery.I have already change my phone and sim for this reason under my warranty,if anyone give advise for this problem it will be really helpfull,thanks.

its a normal thing when some kind of background data or sync or net is active it will turn "H" and when not internet is active it will stay "3G"..

HSDPA/3G automatic switching

Hello,
I have just upgraded to the official GPS ROM and I am on the Swedish 3 operator. I have noticed since the upgrade that the network connection is switching from 3G to HSDPA when there is a demand of bandwidth or simply when there is data in either direction.
I can see that the purpose of this was to make it possible and more reliable to place and receive calls during data sessions. I have figured out though, that with the old ROM, there was no such switching (but there was no distinction with the icon, so you really had no idea) and the connection speed was always constantly 1Mbits/s when using Internet Sharing for example. Now with the HSDPA/3G switching/throttling, the connection often drops down to 3G speeds and Skype-calls are lacking quality from this a bit when using Skype in the car which i do quite regularly nowadays using my Jabra JX-10 headset.
I also realize that there is still a problem with outgoing and incoming calls during these automaticly switched-on HSDPA-sessions. That is probably why HTC has decided to keep the HSDPA sessions as short as possible, that's fine, but what boggles me is the algorithm used for the switching. It seems to always kick in HSDPA in the beginning of a new data session, and after a short time of inactivity (while pondering what favourite page to open this time) the connection drops down to 3G and it won't kick back to HSDPA even when you start browsing again, until a certain period of "non-HSDPA-ratio" has been reached and the phone thinks it would be OK to kick in the highspeed again for a little while.
I also noticed that using Skype would keep HSDPA alive once you place a call from a fresh started data session and keep talking ;-)
This is not a particular problem to me, I was just wondering of anyone else here has noticed and had an idea of what the programmers had in mind?
BTW: I am running TomTom 6.010 and Franson GpsGate on the machine now and it works absolutely like a dream. I used to have a Blue-I Bluetooth GPS in the car (Trimble based chipset, only 8 channels but quite OK piece of hardware) but this is far superior when it comes to HOLDING a persistent fix also when moving indoors. The TTFF is quite fast as long as you are outdoors, most of the time i have a fix before i leave the parking space. I noticed there being a dynamic number of satellites of the receiver, sometimes i see 7 out of 8 satellites, and then sometimes i see 10 out of 12! Anyone noticed?
Thanks in advance! Cheers...
It’s not your phone that decide to change from HSDPA mode to normal R99 (384kbits) mode and vice versa. Everything are always controlled by the network. The behaviors that you describe are normal. Besides the HSDPA is quit new for the operators and new parameters needs to be tuned for best performance for every users.
BTW, the degradation that you notice. You are not alone that use HSDPA.... Its finally the big success for 3G
I use Phone Alarm profiles and BandSwitch to control my connection based on business hours. I get a poor singal unless on 3G where my office is located. I force it to GPRS otherwise to save battery.
I have similar problems, cannot receive or start calls when HSDPA connected. Shouldn't that be possible anyway, calling and transferring data at the same time? Or is this a network provider problem?
I too am on the Swedish operator 3. I have an unlocked, non-operator distributed HTC TyTN that I had updated the radio to 1.40xxx and the ROM to Black Dymond 3.5 and was having the exact same problem. I could reproduce the incoming call not getting through error every single time I got the phone to go into HSDPA mode.
After some initial searching I read somewhere it was network dependent (Nokia switches vs Ericsson) and the only way to solve it was to disable the HSDPA using e.g. HTweakC, which I did and it solved the problem, but then of course I couldn't take advantage of the high-speed data access, which was the major reason I got this phone.
I recently noticed that 3 released a new extended ROM with instructions to update the ROM to the latest (as is available on the ftp here) then install their ExtROM. I went to the trouble to try and breakdown what was in this extended ROM, but being a newbie to pocketpc it was all hyroglyphics to me, so I went ahead and installed it over my old HTC ext ROM (which I saved for later use just in case).
When I get around to it I may mount this extended ROM here (I have it, but don't have too much time to put it up right now, so someone may beat me to it).
Anyway, Black Dymond 3.5 didn't install the Extended ROM after a hard reset (assuming that was the intention), so I did it myself afterwards. One initial bug that showed up quickly was the Comm Manager not wanting to start saying it would only manage a max of 7 items (whatever that means). So I installed Schaps latest Comm Manager and it worked fine.
Well, guess what, now there's a daemond that starts on boot and the phone app is different (another bug is that the text on the phone app buttons remain in the 3 theme although I changed back to black, but that's minor), but now I cannot replicate the no incoming calls during HSDPA error.
Apparently they've added something that makes the phone connect properly to their 3G/HSDPA network for call handling. Now I've got full HSDPA speed and no problem on incoming calls (plus still have Black Dymond's great VOIP/SIP WM6 solution).
Ok, as a noob I of course missed the fact that the daemon starting at boot is Voice Commander. Still the actual phone app/dll is somehow different with this ExtROM and it's solved my problems.

1.66 question.

Hi everyone.
Since upgrading to 1.66, I have noticed something rather annoying and hope someone can provide a solution to fixing it.
When I was on 1.48, the H icon at the top of the screen would always be there. I was effectively connected to the internet all the time, and was able to leave MSN messenger etc open and I'd always be online.
When I upgraded to 1.66, the icon at the top of the screen is always 3G. It only changes to H when I'm actually using the internet. If I open the browser and check out a website, the 3G changes to H and the website begins to load. It changes back to 3G when any internet connectivity is idle.
I can only access the internet when H is displayed, but I want it connected permanently like it was on 1.48.
It's like the phone is disconnecting from the internet when I'm not using the browser. It's not very useful when I need to keep MSN messenger open all day.
Thanks.
It's not disconnected when it says 3G. It simply switches to the slower mode when nothing is being transferred to save resources. As soon as something actually needs to be transferred it goes to H again to get the fastest available speed.

Ah, okay. I can't seem to visit any websites when 3G is displayed though. Perhaps that could be to do with my operator settings or something?
i have had the same problem since installing the sms patches.... i have since hard reset to remove the patch... and testing it now... it is very anoying because it keeps my msn disconnected...
I'm using Dutty's 1.5 (it's a great ROM!) with a 2.07 radio and I've got the same problem..
When it says 3G, nothing seems to come through.. when it changes to H, the webpage starts loading...
Does anyone have a fix to make it not switch back and forth between H and 3G? It gets frustrating because it often takes 1 or 2 seconds to switch between the modes....

Let us know how to you get on because I need this fixed.
My MSN stays connected fine in 3G. Push email works perfect too.
The icons only show the available type of signal.
They don't mean you are connected.
When you do connect by opening an app that uses the appropriate signal then the icon changes to show the signal that you are connected with.
If H is not available in a particular area then it will stay on 3G and if that's not available then G with show.
Hey guys. I'm on my 4th HD2 handset now since upgrading my vodafone contract one month ago. First two handsets had similar probs as allot of you have had, i.e sms not working, alarm not working etc etc. I upgraded to the 1.66 rom when i got my 3rd handset from phones4u. I then started getting the same issues as you just described- internet only profficiently working when H coverage is active. When it goes below that then nothing happens at all. I returned the handset today and got a new one. This one already had the 1.66 Rom update installed and sure enough, had the same internet issues. I started fiddling with settings and changed the band setting from 'auto' to 'WCDMA'. ( just trial and error, so senior members please chime in if i have given bad advise!) This seems to keep the network coverage constantly in H and since changing it several hours ago i have not had any issues.
Start> Settings>Wireless controls>Phone>Band> Change Auto to WCDMA
Give it a go!

Wouldnt that make the phone stick to the 3G/HSDPA/WCDMA band only and cause the phone to have no reception around certain areas that still operate on 2G GSM?
Exact.
I rather tend to do the opposite for that reason if I have trouble (sometimes you're in areas where 3G reception is low and it keeps switching between 3G and EDGE all the time), I'll force EDGE only. It's slower, but at least the connection is constant.
When at work mine fights bewteen 3g and h and both are like 1 bar signals, i'd rather disable both when at work as G is full signal.
Is there a way?

frustrated with hd2 losing signal

I have trying to use the HD2 over the last 3 days and getting real problems with intermittent signal loss.
I know i have low signal from the mobile operator in some parts of my home but that has never been a problem with other HTC phones i used before. If the signal was too weak it would just drop out but come back if i moved a bit.
With the HD2 once the signal indicator turns red it stays that way even if i move to a strong signal area.
The weird thing is sometimes i would leave the phone sitting in one place with four bars and then minutes later it would show up with no signal and i can't receive calls.
Even stranger is that in all these cases where there is no apparent signal, all i need to do is press the send button to try making a call and the signal "magically" re-appears and all is fine. I've tried at least four differnt radios as well as the energy ROM ... no change.
Any ideas ? this is reaallly frustrating!!!!!!
do the problems resemble what I experienced here?:

change radio ROM, well experiment with several of them by trial and error (read the sticky/tutorial first).
OR
buy an indoor signal booster.
Well, regardless of the radio version ive had really odd intermitant service.
the best way ive found to help this is turn off 3G / HSDPA
Doing this forces the device to remain on GPRS, it means the battery lasts a hell of a lot longer and it doent drop the connection every time the device feels like trying to connect with HSDPA or drops it for no apparent reason.

it seem that you were losing data connection .... i'm a lot worse off ... i lose data AND voice .. all connectivity ... so i don't receive calls
as i said the weird thing is as soon as press send to initiate a call,cthe signal bars come back and everything works fine!!
as i said, stop 3G from working, when switching between the two due to what ever reason the HD2 decides to drop it will kill your connection, voice and all until it switches back. there is an issue with 3G and im wondering if its everyone or just folk using TMOUS radio and thus recieving the extra RAM
To disable 3G/HSDPA to test,
Open Comm Manager and click on Phone (not the on/off switch) to go to phone options. Scroll to bottom and select BAND. Switch network type from Auto to GSM.
3G/HSDPA is only needed for internet surfing. Time, weather, stock updates and email downloads don't really benefit from it. So turning it off this way will make these type data connections go through the EDGE network which is plenty fast enough for it. When you need to surf the net, go back and switch it to Auto and you will get 3G or faster speeds for that.

hello im having the same problem..no voice or data i push my send button an then i get signal,my wife has a hd7 and my son has a hd2 they will have 3 to 4 bars and i show no signal.push talk and i get 1 to 2 bars.
have you found a fix?
You could always try a signal booster on eBay for like 5...

If its just 3G then its probable just T-Mobile or then again a Hardware/Firmware issue
try a different ROM, Radio
I have this same issue I running a T-Mobile USA (using radio 2.12 but then again it was doing it on 2.15 as well) and it just drops all connectivity and says no service I have to search the network again.
My phone is unlocked I don't know if that might have anything to do with it as well
I've had this problem on my HD2 since i got it.
Edge (E), works but slow as all get out. 2-4s ping times or time outs. 3G (and when i say 3G i mean when it says 3G in the status bar) doesn't work at all. HSDPA (H) works great, WHEN it stays that way, which it doesn't.
It can switch between 3G to H every 10 seconds.
And i'm using it for tethering primarily, which makes working painful. Lose your VPN and SSH sessions constantly. Some days it's ok. But most, horrible. btw, i'm in the Denver area.
I've tried stock roms and custom roms (primarily Energy). All radios. Nothing fixes it!
This is the only thing I don't like about my HD2 and/or t-mobile. And it's a whopper. I'm almost ready to get another phone or carrier, depending on what's causing this.

I have 4 HD2's with one having the problem you describe and have come to the conclusion it's a hardware issue. Probably a cold solder joint on the antenna lead.
In WinMo or Android the signal bars jump all over the place but the signal level in 'about phone' shows a constant signal even though the bars show nothing. I don't drop to many calls but miss more than a few incoming. I travel for 5-8 hrs in the same area everyday and very familiar of good and bad areas of reception. I have tried stock/cooked ROM's/Radio's with no noticeable difference.
I'll probably send mine in to HTC to be looked at.

Constant switching between 3G and 3G+, kills internet

Hi everyone,
I have an omnia 7 on contract with Optus here in Australia. I have had it for a few days now and I've found the data connection to be very patchy, even though I have full reception where I live.
I have noticed the connection icon switching between 3G and 3G+ pretty much constantly when I'm using it.
This is basically what is happening as I try it at the moment:
- Icon says 3G.
- Tried to load the Optus website and the icon changed to 3G+ and the progress bar is just hanging there, wont go any further.
- Icon has changed back to 3G, still hanging.
- Try to load again, now it has changed to 3G+ and the site loaded.
- Icon has changed back to 3G.
- Clicked a link on the website and the icon changed to 3G+, page loaded fine.
- Icon changed back to 3G.
- Tried to load the facebook app, "Unable to connect to Facebook. Please try again later.
- Trying to load optuszoo.com.au again, icon says 3G.. just hanging there again.
- Icon has changed to 3G+, still hanging.
- Icon has changed to 3G, still hanging.
Could this be a fault with my phone? I'm in an area of strong reception, it shouldn't have a problem getting a steady 3G+ connection (I used to have a HTC Diamond which always had a strong HSDPA signal). I can only guess that every time it switches from 3G to 3G+ it loses the connection, which stops things from loading & syncing. Is there anything I can try here before I take it back to the store? I do not have the new firmware, and don't particularly want to try messing with it if I have to return it.
Every Omnia 7 has this problem (as far as I'm aware). It's a connectivity bug with Windows Phone, hopefully it will get sorted in the coming update.

I've got the same phone and on the same carrier and I can't say I have experienced these problems. I've had my phone since october last year and its been working flawlessly when there's a good signal.
When it switches between 3G and 3G+(H), it usually just means the download speed is varying between those 2 standards (i think 3G = about 3Mbits/s, and 3G+/H is about 7Mbits/s).
Only thing I can suggest is turn off your phone, make sure your sim is inserted properly as well as battery, and turn it back on.
If you were on a different carrier with your old HTC, it might be Optus' coverage.

I was on Optus previously, I dropped into the optus store yesterday and they had me on the phone with support. We tried my sim in a different phone and determined it's my handset that is the problem. As the poster above you mentioned, it's probably a firmware issue... but I'm not going to risk waiting for the new firmware to come out because I only have another week to be able to get a replacement.
Had such issues but after I changed my Provider my 3G+ signal ist stable.
Hour handset is being 'elevated' to HSDPA when your using your connection.
When its idle, it will drop back to 'standard'
My handset does this, but i am not getting the data issues your experiencing.
In addition, both my old HTC handsets used to do this, tho the icon actually showed [H] for HSDPA (Windows Mobile 6.1 and 6.5)
Hard reset your Omnia And/Or send it off for repair/replace
(I am with Optus too)
I'm having the same problem.
I've got a Samsung Galaxy s on Optus.
Constantly changes from 3G to HSDPA, looses connection every time, very hard to use apps that use the Internet.
Seem's to be an optus problem as this is happening with different types of handsets.
Maybe an option where you can select 3G or HSDPA only is needed, they have a GPRS or 3G only option so i don't see why they cant have this aswell.

Yep I ended up taking it back and getting a replacement, but the replacement has the same problem... so it's either software related or network related.
I can confirm this issue too.
It's REALLY annoying.
Is there any temporary fix? I hate this device for the most part, but I love WP7.
I have less problems when I have the phone's sync set to hourly, then it happens maybe once a month that I can't connect with data.
When I had de sync set to manual I almost daily had to reset the phone to get the data connection back, now its on hourly sync again and no problems in the past week..

I have the exact same issue with my HTC Mozart. The signal constantly keeps changing between 3G and HSDPA when I'm in an area that has stable strong reception.
This causes the same DNS issues as stated in IE in which websites fail to load until you refresh them a number of times.
To me it appears that its an issue with IE and the way WP7 calculates and handles the signal. Can anyone confirm if Microsoft have confirmed that there are issues with IE and the signal and when this will be fixed?
I don't know if in my case it's related to the same problem, but on my operator's network it's mostly E and 3G.
After a few times of checking my email, getting the People Hub updated or surfing once in a while, I don't get a connection anymore, except when connecting via wifi.
This is a very annoying problem and the only way to get it back is turning the device off and on daily basis, sometimes even a few times a day D:
I have the same issue ever since I updated the firmware. At first I thought that it is broken internally but it seems to be a universal problem.
Firmware: 2424.11.2.3
Radio: 2424.11.2.2
bootloader:5.2.1.4
Does anybody want to escalate this issue to MS and Samsung? (I understand that several countries are reporting this)
Same problem - HTC One X on Optus.
My phone seems to spend most of its time deciding whether to use 3G or HSDPA, during which time my webpage downloads stop, I can't connect to facebook ("Connection lost - tap to retry"), I can't search Google, etc. etc.
I wouldn't mind if it got on with the job in the meantime, but while it's flicking backwards & forwards between networks I can't seem to get any data down (or up).
Really, really, really annoying. I didn't notice it on Telstra, but I had a different phone (HTC Desire). From the looks of this thread though it's network-related, not phone-related.
Does anybody have problem while calling someone, and when line establishes, there is only silence and dropped call. I had that problem, and I solved it by forcing phone to use only 3G. To do this, go to Diagnosis, and enter *#2263#, then if you want only 3G enter ''WCDMA Band Preference'' - ''WDCMA All'', or for EDGE ''GSM Band Preference'' - ''GSM All''. Automatic speaks for itself. I use 3G all the time, and no more dropped calls. Maybe this could help with 3G -> 3G+ shifting. Only downside is that when there is no 3G signal, you wont get signal at all.

Same problem - HTC One X on Optus.
My phone seems to spend most of its time deciding whether to use 3G or HSDPA, during which time my webpage downloads stop, I can't connect to facebook ("Connection lost - tap to retry"), I can't search Google, etc. etc.
I wouldn't mind if it got on with the job in the meantime, but while it's flicking backwards & forwards between networks I can't seem to get any data down (or up).
Really, really, really annoying. I didn't notice it on Telstra, but I had a different phone (HTC Desire). From the looks of this thread though it's network-related, not phone-related.

[Q] No 3G internet after switching wifi off

After a couple of days of using my Nexus 4 i've noticed a problem with the way it handles the transition between Wifi and 3G internet.
Usually it works just as expected, when I switch Wifi off (or just go out of wifi range) it automatically switches to 3G internet (coverage icon in blue). The problem is that sometimes, after switching wifi off, it doesn't turn on 3G data (coverage icon remains grey). The only way I can get 3G internet back is turning Airplane Mode on, and then off again. ¿Am I missing something here? I've seen other people having this problem with other phones, but no workaround yet

This happens with my gf's Galaxy S3 too...
I think this is just a network coverage issue. My old mytouch 4g slide had the same problem. Usually it switches quickly if I'm in an area with great reception. If I'm somewhere with weak reception, it takes a little longer.

Well, I don't think this is a network coverage problem because when this problem happens, it can stay for hours with no 3G internet, it just doesn't even try. But then I switch airplane mode on and then off again, and it achieves 3G data connectivity almost immediately. Also, with the same SIM card I didn't have this problem with an iPhone 3GS.
Well, i've been investigating a little bit, and I've just found it in the AOSP issues tracker as "Android Issue #2207"
I've also found some apps like "3G Connection Fix Free" that seems to try to fix it
I'll try them and report back my findings
I think I have this problem too sometimes. I think my phone has other issues, I'm about to send it back to Google because it keeps dropping cell signals as well, but I definitely have this same problem.
Yes, it happened to me as well yesterday.
After I had more than ten hours at home using wifi, it can't switch to 3G automatically when I left home. The only way I did is reboot the phone.
But if I just connected to wifi for few hours it is OK.
Before I use One X, I don't have this problem before, but the problem is I can't access to internet once I am using wifi for more than 36 hours about.
I think there is big problem for Android system related to wifi and 3G access.
I don't think it's a nexus issue at all. It is definitely something else. My phone hands over form wifi to H+ in a matter of seconds every-time.
I believe you might have a coverage issue.
I am having the same issue, and can confirm it is NOT related to coverage. A reboot of the phone will immediately fix the problem. Have also tried disabling the mobile network, then re-enabling it, with no success.

Well, nothing i've tried has worked so far. It looks like if it stays connected to Wifi for many hours (for example overnight), it just won't switch to mobile internet unitl I reboot or do the airplane mode trick. I also have wiped everything and reinstalled the stock rom, but the problem is still there. Has anybody fixed it?
Had this problem with my Nexus One, with my Transformer 300 and now with my Nexus 4.
I use German provider O2 and after doing some research, many people suffer this problem and have O2. I thought it was related to my SIM card and I ordered a new one without success. My wife has O2, too. She never had a problem, not with her HTC Desire, not with her Galaxy Nexus.
I worked around with free app WifiFixer Free, which connects to 3G every 60 minutes. This doesn't seem to work on Jelly Bean, though.
The problem is all but new and I am out of ideas. I now use an app that enters and leaves airplane mode upon leaving a Wi-Fi network. But it yet has to prove that it works...
Any news in here? have the same problem and don't know how to solve it. It's so annoying

I have this problem too. Completely stock nexus 4. It doesn't happen all the time but when it does its very annoying.
