Network and GPS Functionality Vanished - Galaxy S I9000 General

Hi all,
I flashed my phone, and thought I’d go with Darky's Raw Steel Edition (4.1), which is awesome btw. I installed it correctly, installing I9000XWJM8 first (the MODEM and PDA, not CSC as none seemed to come in the package).
Everything was working smoothly until I realise 3G/Data Network is no longer working (it did previously). Not only that but it seems it won’t connect to my service provider (Three) at all (emergency calls only), and I’ve also now noticed GPS doesn’t seem to work at all, I can’t even get into GPS test mode. Wireless does however work though it being off, or on, has no impact.
I’ve tried:
Flashing different firmware - Stock JM8 and Doc Froyo’s latest JPO.
Hard Reset
Deleting and re-entering APN settings, though they were correct and already on the phone anyway.
Testing my SIM on another phone – signal is strong, inc. 3G on that.​
I’m really at a loss here. Any ideas anyone?
Thanks
UPDATE: So, I won't bump this myself, but incase anyone finds this thread in the future: the gprs, gps, 3g, etc all work - just not in my house, on the SGS, anymore. I have no idea why - my other phone, it's fine.. and it used to be fine with this phone too. I'll update again if I figure it out.

the other phone works fine with the same sim you are using in the SGS?

Yep, the same SIM works in my old Nokia 6600 fold, people in my house also with Three are getting solid reception right now. 4-5 bars with 3g established.
It worked beautifully all the way home from work on the bus, just not in/around my house.
It's as if the local cell towers near my house have blocked my SGS specifically (can't receive calls or texts either). I did turn the wireless on and off in short succession (which would cause the gprs/3g to try to re-establish each time).. maybe I flooded them and they blocked my IMEI? Or is that just a ridiculous idea?
The real odd thing is GPS not working either (again, just around my house/street); surely it doesn't need a cell site for that?
It does seem as if I can't download apps from The Market anymore either, and have tried various cache clearing solutions to fix it (problem occurred roughly when I noticed my reception was nill).

You might have a problem with the band selection thing of your phone.. have you tried downloading/speed test when you /do/ get a connection? If it seems capped at 40kbps, you might have the same problem I experienced before, of being stuck on 2g. (Despite settings saying otherwise).
I fixed it by doing the solution to having a missing 850 band, the thread of which is found somewhere in this forum.

Thanks. That sort of worked earlier.
It made a slow data connection, and some texts came through.
I then went out to a location a few miles away, had a look and it was still on a slow connection type for a few mins, then all of a sudden it went to HSPDA (with the occasional 3G flicker) and was blistering fast.
Now that I'm back home, I've lost all reception again and can't make/take calls
[EDIT] Clicking around my phone in the hopes of finding something: checked product code in my nv_data.bin file with SGS Toolbox, and it's showing I9000HKDKOR; whilst the backup is showing I9000HKDH3G - could I be on to something? I backed up my efs folder after rooting before doing anything else - so, going to try restoring that.

I have a hunch based on a 2 year old post (http://forum.xda-developers.com/showthread.php?t=445913).
From what I understand, Three UK piggy back on Orange's network when Three's 3G cell towers are out of reach. Orange don't provide Three users with the full service though, just 2G and I'm guessing they prioritise Orange customer traffic.
I think when I flashed my phone, I removed code commanding the phone to prefer Three cell towers. Without that code, the phone simply goes to the strongest/first signal it detects. I'm guessing in the area near where I live, it's Orange (or maybe any old network which is why I'm often getting Emergency Calls only).
This is all guesswork. I'm hopeful, seeing as if I quickly switch the SIM to my two+ year old phone, then I quickly get 5 bars and 3G.. unless the SGS's signal issues really are *that* bad.

Try see if you have the symptom of a missing band?

Hi Nwsk, I tried that before and assumed it didn't work, but actually the change isn't sticking. Which seems to be the case for a couple of others! Thanks for pointing me back to it!
[Edit]
Ohhhh dear. Now I have another theory (I really hope I'm wrong).
I've just read on a thread that some phones don't have the 850 Band, it's down to a lack of hardware support. I'd wager every Three UK branded phone sold will have the correct hardware as stock. I sent my phone back to Samsung for repair, they said they replaced the motherboard.. inference: they replaced it with one without the WCDMA 850 support.

Hmm, I'm definitely no authority on this, since I'm just guessing.. but I figure if that if was a true hardware defect, you wouldn't even be able to get it temporarily?
Are you using any 'battery-saving' type apps? Something might be messing up and keep reverting the settings. I had this occur to me a second time when I was trying out the superpower app here, I think it conflicted with another app I was using, and it borked out my network connectivity. Somehow fixed that after a few reboots, and lots of messing around in the phone debug menu with the 3g/2g thing, it suddenly worked again.

I've not seen it manage to get onto 850MHz WCDMA in my house for a while, not since the mobo got replaced (I should qualify that with a statement on my bad memory ). It will occasionally latch onto something if I walk around the house, giving me a slow data connection with the G symbol showing - it will drop pretty quickly.
Messing around while I write this, I've just realised if I set my phone to GSM(2G) with roaming [Three UK phones need this on so they can connect to Orange towers], then it does establish a data connection at 1800mhz. If I force WCDMA only, I get NOTHING. Setting both/auto leads to it being dodgy/instable, as I've discribed above.
My Nokia 6600 supports 850mhz UMTS, which would explain why it's working well inside my house.
I don't think it's an app. I've flashed a few different firmwares in an effort to get this fixed, it's currently on official Froyo JPO (not even rooted!) with Multi-CSC and a few completely harmless apps. I'd try the stock Three firmware if it was available somewhere.
I'm hoping it's software like you suggest! I will tinker away for now!
Thanks for all the help, at least now I'm fairly sure I'm on the right track!

Unsuitable radio or poor data services from UK mobile networks...?

Hi guys,
I don't know how many of you are living in UK or if you experience this in other parts of the world. Basically there's one thing that really annoys me and I can't figure out WHAT'S causing it!
I am well satisfied with my Leo but as to web services I am not so enthusiastic. Firstly I've given up on "My location & weather" services exactly the same way as I did on Blackstone. I just don't bother setting them up after ROM update, so they don't show up on the homescreen and I turn the weather tab off instantly after flash. Reason being: THEY ONLY UPDATE IN CERTAIN LOCATIONS EVEN THOUGH I'VE GOT FULL HSDPA OR 3G SIGNAL COVERAGE ALMOST EVERYWHERE I GO!!!
No idea why this is happening. At home where I've got full 3G and GPRS signal coverage, it updates quickly and nicely. But when I go to work where there's full HSDPA, 3G and also GPRS it will not update whatever trick I try!!! It just pops out a message about not being able to connect... Same thing in town centre and other locations. It seems totally random to me where it works and where it doesn't. And folks: I just hate having 12 hours old location and weather report on my screeen before coming back home or wherever it decides to work!
Now secondly, similar thing happens with web browsers. Because of unsupported flash in Opera I have started using Skyfire in larger scale and recently also the uZARD, if anyone came across to that. They are both good browsers (in my opinion the uZard is nearing perfection!) but strangely a similar issue to the one above comes with them. Again they only seem to work in certain places and again there is quite a decent data coverage almost everywhere in my area.
So the question is: does it have something to do with data services of my network (UK Orange) or is it something radio related maybe? I have tried 2.06, 2.08 and 2.10 radios and there wasn't any significant difference.
Does it ring a bell? Did anyone experience this?

I'm on o2 I'm and have found the new 2.10th radios to give an extra bar and speed improvements network wise. the latest is awesome but consumes more battery life for me so i went back to 2.10.50.08.2
hope this helps
Im on Virgin in the UK, where i live i have full signal where ever i i am in my town, my location doesn't work simple, i added my own city, my internet works fine, now i have been house sitting for my dad for 2 weeks in a little village, 2 weeks only just had 1 bar of signal and my location worked now wtf is that all about lol, oh my radio in my sig
Im on tmobile uk and when I'm at home I'm lucky if I get 1 bar of 3g coverage, if I dont I'll only get 2 bars of gprs, then again we are behind a ruddy great hill, most other urban areas give good 3g, however like the OP says sometimes theres an issue with speed and location not updating (or updating to the wrong location) despite full coverage
My gf is on vodafone and at home shes lucky if she gets one bar of gprs
But then thats what she deserves for having a iphone!
I've never tried another radio but I'm considering it
Update
Just to let you guys know, UK Orange was going through some major technical difficulties with their 3G network lately. So that has been the cause for trouble with browsers.
But the first problem I've mentioned is a fact that MY LOCATION and WEATHER still only updates on certain (random) places, regardless the signal coverage or radio version!!!
Works fine for me wherever I go on O2 as long as I have somes signal, just takes longer on GPRS.
In my experience of friends on Orange, they've never been good.
Try SPB weather and see if that works.
Alternatively, try updating in an Orange shop, if it fails, ask if you can use one of their handsets to try, and if that works, you'll know it's a problem with your phone so time to get it replaced, if it doesn't work, you'll know Orange are just poo.
Weather Locations has never worked for me. Just look for the cab named something like Dutty's disable current location and it will remove that my location entry in the weather so it will never bother you. Then just manually add your city and job done!
As for the web browsers not working, i had intermittent drops (its ok now tho). but what i did before, was disable HDSPA. the phone kept switching betweeen 3g and hdspa and cudnt make its mind up, and so it wouldnt connect to the net. But as you said Orange have been messing up so it should work soon.

I have to ask how often is it set to update? i have mine set to update every 3 hours and it does. The location accuracy can be a little off at times but i don't really rely on it and if i do notice i'll do a manual update which works first time 99% of the time.
Poor 3G/HSDPA signal (2 bars or less) will cause some crazy packet loss and will cause problems with internet connectivity in general. Most often the phone will fall back to EDGE and then GPRS in order to correct this (but for saking the speed). If the signal is still crap then there is no hope. I'm on O2 and my radio version is in my signature. I was using 2.07 (stock) and that wasn't brilliant and i have heard that the newer radios suck the battery and the wifi isn't so great.
If your signal is pants even with the new radio i would advise you lay your hands on an extended battery and leave the wifi chip turned on. Then if you configure to connect any unsecure networks first as soon as it finds one you'll have net access.

Hi,
It was set to update every 1 hour and as I said before, there's quite decent signal coverage in my area. I usually have full HSDPA and 3G signal at work and about half of 3G and full GPRS at home. The only time I can think of when I have poor or no connection is on the train (when passing through places with funny welsh names like Llanharran or Pontyclun... ). Still MY LOCATION won't update at work, or central train station or city centre. As a paradox, it updates nicely at home...
Anyway, for sake of having the weather animation on and updating, I have used Dutty's "Disable current location" cab mentioned above. Now the weather service updates fine on manually chosen locations. So bye bye MY LOCATION...
I'm on O2 (UK) and have noticed that all but my local transmitter actually allows weather/location updates.
I did a pretty big test - I drove from the south coast to Edinburgh the other week, and had it updating every 15 mins.
It updated every step of the way.
I'm sitting at home, and it doesn't update.
I've already got hold of my local O2 engineer and he is looking into it as he thinks he knows what the problem is.
The Problem is Orange.....

I had the same problem in East Anglia with Orange
Switch of 3g and the weather will update
GPRS data works fine, but 3g/hsdpa data was not working i complained to orange and looked on the net loads of other people in this area were having the same trouble....(voice was fine though)
About 2 weeks ago it started working fine except when im surfing i get 'orange safeguard' blocking sites ...it even blocks this site!
its not because ive got safeguard enabled. it's because orange cant establish my identity!
I bet if streamed loads of TV they would identify me for sure...
on orange in cardiff aswel, i find that even though i have a strong 3g signal some times the internet just doesn't work,which gets really annoying, as normally have to terminate the 3g connection then restart it to work.
been reading this thread if any intrest
forum.xda-developers.com/showthread.php?t=614119&page=45
it says about people using the chucky tabtastic ROM, and the problem is gone. but I'm happy with the ROM I'm using, so really wish i knew a fix for this!
On O2 in Nottingham and just recently it's been awful.
I've gone through a multitude of radios and none work with data properly. Weather services always show "My Location" or cannot update. Google maps takes about 10mins to load one square of the map (so GPS navigation is out of the question as the marker moves to a region of the map that isn't updated and takes forever to load).
Opera can now take anywhere between 15 seconds and 5 minutes just to load the Google homepage.
Thing is, about 2 months ago it was perfect, speedy as anything, running fine. Like I said i've gone through various radio roms and have settled on 2.10.50.08_2 at the mo as it gives the best battery life for me, but even with full 3g/hsdpa signals i get rubbish data performance.
I know that stopping and starting the data connection sometimes fixes it, but I'm not prepared to continually stop and start connections just to be able to browse the web.
I've tried switching from 3G to 2G mode at work so the device started using GPRS signal instead of HSDPA but there was no joy either. Initially I would incline to idea that this would be a problem of Orange UK only but it seems now that people using other networks are experiencing the same. I wish I could only guess how much of this is caused by the technical breakdown Orange UK (and maybe other networks?) were recently going through. I think the actual efficiency of MY LOCATION service in UK was never great...
I'm on Vodafone, Kingston upon Thames,
Radio: 2.10.50.26 (Leon Rom)
Had the same problems ( almost all stated in here ) with the new radio i have full bars 70% of the time on almost all connections at home, and before, i used to have 1 max 2 (the house is in a "bad"/"blind" vodafone coverage area), so this radio seems to work for me.
Still:
the weather i won't mention that it never worked regardless of signal or not, regardless of the connection or radio... then i found something into the menu under the GPS folder... called Quick GPS . I realized that is not a data download problem (as any manually set out location works), it was just a simple "i will tell you the local weather info as soon as i bloody find out where the heck we are" phone problem.
Well all you have to do, is set up the satellites to download automatically and/or update manually when you travel extreme distances... it will definitely improve location tracking as it sets the "default" satellites settings in your area, and to be honest with you, since i set that up, i NEVER had weather/location problems at home or anywhere else. Is just a small tweak witch you won't realize is linked directly to the location service until you open the Quick GPS thing.
For the radio, at least for vodafone users, i recommend the above one. just give it a try as it has decent battery life and a better connection, also everywhere i go i seem to have a working stable connection for data (at least for me it worked, and i do travel alot, needles to say that my laptop gets it's internet from my phone during travels, so bye bye dongle ).
Give it a try, it may really work out.

hmm... i think is not related to networks more than it needs the network connection to download data (especially that you said the connections are working fine most of the times), location is definitely related to the GPS receiver and the GPS settings (Global Positioning System remember? witch in my book is Location ...), witch apparently on the Leos around UK are not set properly by default.
This is probably why mine works flawlessly. I set WM to use the inbuilt GPS all the time so i don't have to mess about with turning it on in google maps. I don't use QuickGPS because that is about as accurate as as dropping a brick out of a plane at 35,000ft with your eyes closed. Atleast with proper GPS it's accurate to within 20 metres.
when i had the tmobile g1, weather plugin worked almost flawlessly with only odd times it didnt update correctly. but with the hd2 ive been having the same problem recently on tmobile (was on tmobile wiwith the g1 aswell).
Im using the eu rom that allows 576mb ram .
Ive just flashed a new rom and it seems to have detected my location just fine at home. I will know tomorrow when i go to work if it upodates correctly.

Thanks for the post man Ive been trying many different Radios to get a stable connection with VF I also live in an iffy area so i'll give this one a try and see if it works for me!

easy! go into settings in sense, hit menu, all settings. Then go to the system folder and external GPS and set a com port (mine is set to com4)
Job done. Sense will pick it up automatically and then all you need to do is tell google maps it's configued by windows.
Finally disable quickgps by hitting start, tools quickgps and then menu options and uncheck "download quickgps automatically" and "download quickgps when roaming" this will stop it updating when not connected to the pc and save on your data plan if it's limited but allows for a backup to the true gps if for some reason all the satellites get taken out.
**edit** i picked up this tip from a collegue that had a touch pro (well we all did but i left before they got the n900 upgrades) and a tomtom external bluetooth receiver and it appears to work with the internal reveiver on newer devices

GPS Issue, only in some areas. GSM network dependent.

Bit of an odd one. Basically at home with the phone on my home network T-Mobile I simply can't get a GPS fix. This problem has only happened in the last couple of weeks previously its been fine, a fix within seconds.
As some of you may know T-Mobile and Orange in the UK have now enabled roaming between the 2 networks. If I force the phone to roam onto Orange I get a GPS fix with-in a minute. Switch the network back to T-Mobile back to no fix.
If I'm in a different area, network on T-Mobile, fix within seconds. I thought maybe it's quick GPS wrongly loading the wrong area because of an issue in the cell db, I've set quick GPS to never update and now the GPS appears to cold start although quick GPS still says the data it has is valid for x number of days.
I've tried defaulting the phone but exactly the same with defaults and using GPS Test rather than TomTom.
Does anyone have any ideas? Is anyone else having the same issue?
I just tried another test. I roamed onto Orange and got a GPS fix in TomTom, I then set my network back to T-Mobile and the GPS fix was lost! As I switched networks I left TomTom running in the background.
A bit more testing. If I force the phone onto 3G T-Mobile the GPS works fine. My theory is what ever frequency the cell here operates on (some 5 miles away in the 1800MHz band) must be causing the some issue with the hardware
I'm thinking that most people wouldn't be able to experiment to see this, I'm just lucky or unlucky depending on how you look at it that I'm in a position where I can switch networks therefore changing frequency within the 1800MHz band and I can stay in the same place to test it. I've had in the past where the GPS would loose its fix for no reason and then just come back while travelling on a motorway I wonder if this was the same thing. Also the chances of someone owning a HD2 using the GPS and being on a cell who's frequency causes a problem is pretty small, and if your travelling you're likely to just think it's dropped for some reason, and oh yes it's back again now so think no more of it.
You are getting confused between GPS and GPRS.
GPS is the satellite system that you use to pinpoint your location (as with TomTom). If your phone is indoors or has a restricted view of the sky, then it cannot receive a signal.
GPRS is a data connection between your phone and the telecoms company. It is basically 2.5G, which way a intermediate step before 3G became set up.

No, completely understand the difference between GPRS and GPS
I've proven with out a doubt that when using the t-mobile cell serving our house (2g) there is no GPS signal. Use another network still 1800 and there is GPS, use 3g, or move to another area on t-mobile there is GPS.
GPS was working at home while on t-mobile upto a couple of weeks ago, I can only think that the cell has had some work done and has changed frequency.

Silly question, but have you got AGPS activated? Because it can give you a rough location based upon the local cell transmitter info and any GPS satelite signals you may be recieving.

I have AGPS disabled. I doubt my operator supports it. I have tried with QuickGPS disabled and enabled but makes no difference.
If I get a fix while on Orange, leave which ever GPS enabled application I have running, running in the background, force the phone back onto my home network (TMobile), go back to the GPS application there's no fix and no satellite signal being received not even a hint.
I've also tried with the SIM card removed and GPS performs perfectly!
Thank you, I thought I was going mad - my GPS has been working perfectly since I got the phone 6 months ago but in the last week has been dropping out or refusing to start at all.
I tried a hard reset, which fixed the problem until I started driving the next day - after a few minutes TomTom lost it's way. Using a bluetooth GPS proved the signal was good, so I was coming around to the idea that the phone was broken...
I have also now read other users that have had GPS problems when roaming, although usually when switching between countries.
Looking on the T-Mobile website about the orange roaming issue it say 'there might be a few quirky side-effects' but I haven't even signed up for the Orange roaming option, sounds like T-Mobile has changed something for everyone?
I have read that fixing the network choice to manual, not auto, can help with GPS issues while roaming - I've yet to test this.

I've had the issue for a couple of weeks I would say. Certainly last weekend I couldn't get a fix for ages when I set off and it wasn't until I was a way away from home that the GPS got a fix. This was before the roaming got switch on, of course it doesn't mean they were not doing something with the cell/network.
I too can get a perfect fix with external GPS or with a GPS nav system, or by changing networks! I've also tried another SIM card in the phone, again T-Mobile and get the same results.
I've attached some screen shots.
1st T-mobile no satellites, you'll notice that there isn't so much of hint of signal.
2nd Changing network.
3rd T-Mobile Orange and GPS fix.
All screen shots were taken with the phone in the same place.
Just come back from a drive just to test the GPS. Basically driven 30 miles away from home fixing the phone to T-Mobile and 2G and the only time I got a GPS fix was when the phone lost signal.
Parked in a layby and switched over to orange and got a fix with in a few seconds! Just can't figure out what the connection with being on T-mobile 2g is!
What Radio version is your phone using?

Have the same issue with various official T-Mobile ROMs.
I had a play with updating my AGPS settings last night using the Google settings from this thread: http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=544421 when working on Orange couldn't notice any difference, with T-Mobile still not GPS fix.
I left the GPS running over night on T-Mobile, admittedly indoors but somewhere I know I get a fix, there was still no fix 7 hours later.
I live in a rural village covered only by one cell mast. GPS starts and runs fine at home with or without the phone turned on. if I walk over the other side of the hill, different cell mast, the GPS drops out immediately - I can't test if 3G fixes the problem as it doesn't work here. Once the GPS has stopped I can't get it to start again, even switching the phone off to airplane mode doesn't help. Only a soft reset, with the phone still in airplane mode will allow the GPS to start.
Switching the phone back on and the GPS drops, however walking back over the hill to home - back to my original cell mast and the GPS starts again.
I'm pretty sure t-mobile have rolled out a change to their 2G system, but not to all masts? rural ones maybe last done hence why my home cell still works.
How to proceed from here? T-Mobile are kind of hard to talk to.....
One thing I did notice was in Memory Map the satellite view normally flicks across satellite numbers until it finds a signal, if the T-Mobile problem occurs this process stops and it would appear to have frozen the service?
I take back the hard to talk to part of my last post, I emailed support from the website and they phoned me back within 2 hours!
As to be expected they couldn't give any instant answers but I gave this thread as a reference and the problem is to be escalated.
The call centerthen phoned me back and asked if I was happy, also to offer me 30 minutes free calls for next 3 months - very nice thank you.
Good work boomboomer. Hopefully T-mobile will find something. I'd like to know what they find, still can't understand the connection between a GSM network and GPS though. I haven't tried a controlled test with flight mode but will try that later. Out of interest what part of the country are you in? maybe it's just a pocket of cells that are affective? I'm in the BA8 postcode area.
The problem certainly only affects 2G, 3G is fine.
I'm out of the country this week but fingers crossed T-Mobile will find the problem. It's nice to know I'm not the only one with a problem.
I'm quite a distance away, DT2 here.
I've been asked to test the GPS over the next few days and keep a log of when and where it doesn't work, they said their network people will ring me soon.
At least this fault is 'interesting' in the words of their technical support guy, he'd never heard of anything like it, so there's hope they will give it some time.
On the plus side they've also given me a free month of internet, so I can't fault their customer support focus.
Incidentally, do you have SPB shell installed? This was the only change I'd made on my phone at the time this problem started.

I didn't get chance to do any testing today at Heathrow as ended up being a bit rushed. I wouldn't say your not a million miles away. 22miles ish, the Cell that covers our home is in Dorset which is pretty useless when you have to call 999 because you get connected to Dorset who then can't pass you to Somerset and you end up being in a situation where you have no way of contacting Somerset 999 not great in this day and age! But I'm not going to get started on that one on this topic.
It's quite possible its a regional problem.
No I haven't installed SPB shell, I have tried it with a defaulted phone but still had the same problem.
I'm out the country now until Friday, but will do some testing when I return on my return journey. I'll fix the phone to 2g T-mobile and keep an eye on where the GPS drops out.
Oh dear, just got a call from T-Mobile technical networks - they don't support GPS as part of their service and won't be spending any time on the problem, case closed. They did say the problem seems to be with HTC devices only, blackberrys are not effected so it sounds like they have heard of the issue eleswhere?
Looks like it's a network switch required to solve the problem, shame that as I've been with T-Mobile for over 7 years.

Hmm, T-Mobile sold me the phone for use on their network, the phone is sold with a GPS, that now doesn't work on their network surely they need to spend sometime working with HTC to resolve the problem.
I do have a case open with HTC under the ref 10gbc410001235 they were supposed to be taking it up with tier 2 but as yet I've not heard anything back. I'll have to follow it up when I'm back in the UK. It might be worth you also logging a fault with HTC quoting my ref. at least if 2 people call in with the same problem they may start to think it's not just one crazy with the issue!
My other half has a HTC Desire, I haven't checked the GPS on her phone. Not sure if they use the same chipset, of course one is WM the other android. I wonder if its a problem for all HTC phones or just the HD2?

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, and this give it to me lots of problems with the battery...
If you love WP7, you should see WP10.

Possible fix for data stalling issues some of us are having.

Right, a little back story.
I brought my SGS2 at the start of May in the UK on O2 so I have an early model which came with the firmware before KE1. I rooted in the first week and was flashing Villainrom 1.0 before too long with no data problems.
I think it was around KE2 with Lite'ning rom that I first saw my phone constantly switching between H & 3G and stalling when receiving or sending data. This behaviour has continued through all the firmwares I've tried with many different modems. I moved onto to Cognition when it was v1.01 and have been using it all the way unto 1.2 with the KG3 modem. Again still with data connecting problems.
Things I have tried -
Turning off fast dormacy
Editing the build.prop http://forum.xda-developers.com/showthread.php?t=1097612&highlight=build.prop pages 1-5
Switching off HSDPA/HSUPA via the *#301279# command
Disabling juice defender
Switching to WCDMA only
Changing modems
Full hard reset and reflasing of roms
Even with the above on multiple roms and rom versions my data connection was unreliable at best and killing spree warranting at its worst.
Possible fix-
What i found lurking on XDA on a slow day at work was the command below
*#2263#
This allows you to select which bands your phone uses. I selected option 2 then tested the 4 available bands. They all resulted in a complete loss of reception except WCDMA 2100. this is probably network specific you'll need to try it yourselves.
The results and current settings
Now when I try to use my data connection the phone no longer switches between H & 3G. It will start on 3G then find H and stay there, I see a slight delay if its been in deep sleep or JD has cut the connect but this is normal for the phone to start on 3G to save power.
Fast dormacy - off
build.prop -stock/unedited (I found this worked for me for a while but since 2.3.4 it didnt seem to help)
HSDPA/HSUPA via the *#301279# command - both on
Juice defender - on
WCDMA only selected as when picking a band it doesn't seem to like having a GSM band selected as well (happy to be corrected on that)
Modem KG3 -
Rom cog 1.2 - I'm patiently waiting 1.4 based on KG6 to test my findings.
Conclusion-
Okay it could be that selecting a band does F'all and that I'm seeing better results for a completely different reason. I'm not a developer so my fixing skills amount to playing with stuff I don't fully understand and seeing how more or less broke I've made it.
After thought -
Ive seen on the sensation forum they have discussed the wrong IMEI code being the cause of poor data speeds so I may look into that next.
Please share your experiences and anything else you've tried.
Ive seen on the sensation forum they have discussed the wrong IMEI code being the cause of poor data speeds so I may look into that next.
That should be no connection as IMEI belongs to phone and handshakes with network first .
KG6 modem some report as better .
jje
I will have to give this a try and see how it works, thanks for the share.
I am in the same boat, it is VERY frustrating to say the least. A typical scenario for me is: reading a web page on my S2 for a good few minutes (3g has gone to sleep mode by the time I have finished reading), I click on a link, 3g flashes, H comes up and flashes once.....wait.....wait.......wait......10 seconds later it decides to initiate a connection and take me where I want to go! It does the same thing with the XDA app. I have been onto O2 about this a couple of weeks ago, all they did was give me the settings over the phone (which were the exact same ones I already had) and they also sent me a replacement sim card, suffice to say, there is no change. Now I am convinced its a network problem of some sort, I have a three sim card which I have been trying out and the above problems do not exist anymore when using three, I click a link after 3g has gone to sleep and it goes from 3g to H and initialises the data transfer in one smooth motion. It looks like I'll be getting my PAC code and moving to Three!
would be interested to hear if switching to the 2100 band helps at all seeing as your on O2 as well
Mine is O2 via Giffgaff and no problems at all .
Tested KG6 modem Wi|Fi only and it is a stronger signal .
jje
Yeah, forgot to mention that, I have just enabled it. I can't test at the moment though coz there is no 3G coverage where I am. The only problem with enabling it is you will not be able to connect to GPRS or Edge if you need to. But it is worth testing regardless.
Just been out and about and tried that setting, didn't make much difference unfortunately
Maybe it was a combination of tweaks on my end. What rom & modem are you using?

Villain 2.3 with KG3 modem. The problem has been the same whatever ROM I have used, I even flashed back to O2 stock a couple of weeks ago to see if it was a ROM problem, but that was the same. I can't remember what it was like when I first got the handset though, mine was the first batch as well.

hi
i am just testing now this fix. i have an o2 phone and i did the same changes you did, disable fast dormancy, changed build.prop settings, will let you know after going a few times underground ;-)
gabrio
confirm, this is working, even when i go underground or when the signal goes away, it gets back to H/H+ and works, gabrio
Give it a little while, I think you'll be back saying it didn't work
Personally, I went ahead with my threat and moved over to 3uk, never looked back since with this problem, been perfect!
I've tried it all. Disabled fast dormancy, hspa, toyed with band selection, edited build.prop (btw, don't bother with it, the network settings you find on the web to type in don't work on the s2) you name it - but it would still cut out. Luckily, my phone is unlocked so I switched my provider and now it works like a charm with all the bells and whistles enabled. I can ride the tram all across warsaw and maybe have a handful of 2-3 second hiccups when I'm listening to online radio. Curiously enough, on my previous provider I've noted that there are some areas (like a busy mall - Arkadia) where it would not stall as well as a few other places, and most other areas that were notorious with data hanging. I'm convinced now that it is an issue on the telco side (*cough*Orange*cough*), and too bad because I was on a prepaid plan with them that for roughly $30 I had 7GB of transfer. I guess they figured they can promise the world on their trash network, because nobody would actually use it up. YMMV.
Had this issue with a UK GS2 purchased from Negri using it on AT&T.
Since upgrading to the latest UK firmware with 2.3.4 I have not had the issue going on about 2 weeks now!
Man was that issue annoying. Had to restart the phone sometimes to get data back.
Joe
Ok I did that too though how abt lag? Phone lags a bit opening large sms conversations and browsing home screens.. But peace. Yours too?

[Q] i9505 stuck out of service

Hi,
I have a weird problem with my S4.
At work I have some areas with really bad coverage so sometimes the phone can stay for a few minutes (or even say 1h) out of service.
This is all normal. The coverage sucks, the building is weird, not problem here.
The problem is that when I go outside where the signal is normally full it does not register back to the network.
Even more it does not even go to "emergency only mode". On a few occasions I arrived back home (10Km + drive) until I realized people can't call me because the phone is out of service.
What is even weirder is the fact that on some occasions, even though the (no service) (/) sign is displayed mobile data works just fine.
My previous iPhone did something similar too - it took a while for it to recover signal after exiting the coverage black spots but never more than maximum 5 minutes.
To me it looks like a radio modem issue and maybe this is aggravated by the fact that my carrier uses the same 2100MHz frequency for both Data and Voice.
I would like to know if any of you have experience anything like this or if there is some app available that can monitor what's happening.
what network and firmware you on and wich s4 variant:thumbup:
Sent from my GT-I9505 using xda premium

It's Europe standard i9505.
Network is Digi.Mobil Romania - but I doubt it's relevant since it can't get even emergency only (other networks).
so... any idea?
Android needs to work on it's notification. No Service and the reception bars only gauge voice coverage. You can test this out by using Service Mode to do a PS Only (data) attach instead of the standard PS + CS (voice) attach. It'll say no service, but data will be fine.
Emergency only, is when there is coverage from other operators but not yours. No service, means your way off the grid.
I've noticed the issue you describe and it's only on some firmwares. Try a newer one and see if you still have the same issue. But you might notice a drop in your battery life because your phone will be scanning all the time. If you're happy with no coverage at work, best to just turn it off and then turn it on when your outside.
Best option is to tell your operator about the lack of coverage. There's someone in charge of stats who get's beaten every time you drop a call. You'll get extra attention if you've got other businesses around you, so let them know that too.
Thanks for the reply.
I am already on the latest firmware and I noticed the same behavior on the firmware before this one.
Unfortunately I can't try out other modem versions (from other FW packages) as that would void my warranty.

but...what about reboot phone? i know isnt funny but until u find a problem u can just reboot ur phone while u are going out from ur office...or just try to enable and disable airplane mode
Of course reboot works but I am looking for a solution, not a partial workaround.
The most annoying problem is that if I forget to reboot it when I leave work it will not recover network connectivity even if I am in areas with very good coverage, areas where you would expect your phone to work.
It looks like when it decides to give up it does not try again. It is very weird that it also drops the signal from other networks (the "emergency only") even if it's well in their coverage areas. I guess I will have to switch phones... Even if this issue was present for the iPhone too it never took more than a few minutes for it to recover on its own. And I'm not an apple fan
Just to do some brain ecercise...do u keep in power save when u are out of signal ? Its possible that disable check after few tries
Sent from my GT-I9505 using xda app-developers app
It's not in power save. I only use that function in case of battery emergency.
Same problem here
Hello, I have the EXACT same problem here. I am in Argentina.
Now, I've been in the USA for a few weeks, visiting, and while my phone was roaming, I didn't have a single problem with my phone.
Since I came back, 3 days ago, I haven't had any problems in Argentina, either.
Is it possible that something got activated when the phone was registered to another company? (it was AT&T i believe)
If that's the case... maybe you can try putting a sim card of another company and see if you still have the problem?
Please let me know if you still have the same problem or if you got it solved. I would love to know something more scientific about all this.
I don't know if this is relevant, but my compass is off by about 30 degrees. Maybe my phone is defective?
THANKS FOR ALL YOUR HELP YOU CAN GIVE ME WITH THIS

Hi,
I have a weird problem with my S4.
At work I have some areas with really bad coverage so sometimes the phone can stay for a few minutes (or even say 1h) out of service.
This is all normal. The coverage sucks, the building is weird, not problem here.
The problem is that when I go outside where the signal is normally full it does not register back to the network.
Even more it does not even go to "emergency only mode". On a few occasions I arrived back home (10Km + drive) until I realized people can't call me because the phone is out of service.
What is even weirder is the fact that on some occasions, even though the (no service) (/) sign is displayed mobile data works just fine.
My previous iPhone did something similar too - it took a while for it to recover signal after exiting the coverage black spots but never more than maximum 5 minutes.
To me it looks like a radio modem issue and maybe this is aggravated by the fact that my carrier uses the same 2100MHz frequency for both Data and Voice.
I would like to know if any of you have experience anything like this or if there is some app available that can monitor what's happening.

Hi I have similar issue,
My phone says its out of service or no signal or no network also I checked my sim card in other phone in the same place and it is fine. The i9505 model in ireland meteor provider was running ok until deicided to give a try to another network operator, when I changed the sim card it didnt only catch up the signal from new network provider but also it refuses to catch the old network provider. Funny thing is that I am receiving 3G but no signal bars and no service sign is beeing displayed. I am running latest official BTU (UK) firmware, the phone was never rooted, altough I had to remove the simlock and instal unbranded firmware. The phone worked fine with the newest updates for a month and now I am facing this trouble.
No factory resets nor installing same radio (couple of times) have helped. Also I used odin to instal same firmware (as it has locked bootloader) so I cannot revert back to other stock firmwares, but still no joy.
hope that someone faced the same problems and describe how to solve this issue. thanks
