I've noticed issues with the data connection as well. Standing in one spot in the basement, it will often flip between 3G and H and sometimes completely drop off. Even though cell signal has all bars. I will have to do more tests tonight and report back.

My SGS locks up all the time when I'm in my office. Usually within minutes.

When my buddy gets back into the office I was going to use his fido sim in my SGS for a while. See if it really does have something to do with the whole Bell network handshaking theory.
[Galaxy S I9000 Q&A, Help & Troubleshooting] digi-geek:
Just a thought here -- but --- what if its got something to do with the BAND being used in the west (Cgy/Edm). Perhaps its not so much the data connection --- but toggling between BANDS.

Does anyone know what all the band options mean in the service mode network settings. I know there have been a couple of comments regarding this in the past - but maybe we need to find the most stable frequency and set it to that. I'm on full auto right now, which of course leads to comas.

Another thing to note is that my Hero probably doesn't use the latest HSDPA/HSUPA protocalls that the SGS does. Never any issues with the Hero. Assuming our signal out west is more "spotty" than out east, our phones will be jumping bands trying to establish the most consistent one. By default they will always search for the fastest. But if the fastest ends up being inconsistent, then its always going to be changing. Is it this continuous changing that leads to the coma?

I have to do more research on those settings, but if anyone already knows --- please post and we can test!
[Galaxy S I9000 Q&A, Help & Troubleshooting] renerz:
My phone also doesn't Force Close before comatosing, and occasionally will with the screen on.

I have had it go into a coma 'loop' before, where it would display the SGS start up screen, and when it should have loaded the homescreen, it would coma, repeatedly. I had to three button factory reset the phone then. :(

I have noticed my phone jump between different data connections while being in a moderate signal area....

The only other problem I seem to get with any regularity is that occasionally text messages will fail to send, even when I'm out in the open, with the phone displaying moderate to full signal.

I am in calgary but since I have an asian i9000 my phone only supports 1800MHz so it cannot switch between bands.

?? Not observed on Any Froyo?

Happening in Canada / Europe / Middle East / Australia

And No U.S.A. / No India / No Africa (on these threads atleast) ???

In Canada has happened on Bell and Telus. Any Rogers or others?

I'm going to try a new test tomorrow

only using Combi Bands for 850+1900 on both GSM and WCDMA

and without NoBars, lets see if i can reproduce the Comatose Syndrome using only that.

the phone by default is set to Automatic, using all 4 GSM bands + all 3 WCDMA bands

the idea is the less choices, the less trouble it should have at calculating which tower to stick to.

Only what solved my issue is when APN is off...I tried so many things, but still nothing, only APN. I am from Europe
[Galaxy S I9000 Q&A, Help & Troubleshooting] AllGamer:
if you use combi-bands (service mode)

you can select just 850 (no 1900) for both GSM and WCDMA

that will also prevent the Comatose Syndrome
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJNutty:
Is it possible to do only 1900 (no 850)? Would the 1900 not be faster?

Galaxy S keeps turning off - crashing - shutting down!

Hello All

I’ve had my phone since Sept 18 and I do love it…when it’s not in a coma! I put the phone in its carry case and when I took it out it was “off”. Press the ON/OFF button…nothing. Finally I figured out that if I held the ON button down for 10 seconds the phone would “restart”. It does this constantly. It never charges properly because it keeps going coma during the charge and nothing happens…it’s like it’s crashing. I loaded the latest firmware…still does it. I wiped the phone…still does it. Do a Google search for “Galaxy S shuts down!” or “Galaxy S turns off!” Tons of people are having this issue.

So, what’s wrong and when can we expect a patch or fix! I can’t have a phone that crashes on me. I am missing important calls, text and I can’t babysit it while it charges! Mine seems not to crash if I keep waking it up constantly, but, put it on the bedside table to charge…no way, it’ll never happen! Within 20 minutes it has crashed into a coma.

Husband is taking it back to Best Buy, Cambie Street, Vancouver today, but I see that many people are on their 2nd or 3rd phone and it’s still happening. I’m wondering why this hasn’t gone public as it is a really serious flaw in the phone! Answers anyone? Help! Like I said, I love the phone but as it stands now I can’t keep it if it won’t stay on!

Thank Goodness for this board BTW. I've never written to one of these information groups but I'm glad I found you as I seriously thought I was going nuts! I'm not a tech guru, I just like gadgets and I thought I was doing something wrong to make the phone go coma...

PS I've read lots of people who are thinking it's one app or another, a screen saver, GPS and so on. My phone has done this out of the box, so I really don't think it's an app. The only thing we all seem to have in common is that it happens when the signal strenght is low. At home I only get 1 or 2 bars and it "seems" to happen at home 99% of the time. I have not noticed it happen when I am in town, or where there is stronger reception.

Why, how or what would cause this to happen? I've always loved my Samsung phones but this just stinks. I'll keep reading and have posted this on the Facebook Samsung Fan site. Hope it's fixed soon...can I really be saddled with this dud for the next 3 years! My contract is with BELL!

PSS. I've never had to send a phone in for repairs...what happens to your calls? Your information that is personal and on the phone? What if someone calls you on the number when it's at some repair shop? How the heck does that all work? Can they just put my card into a new phone if my husband makes enough noise about a three week old phone crapping out??

Ok sorry this is long.

Clueless

Lookieloo - Samsung/Bell has extended the return/exchange/repair policy for 60 days from purchase.

You can reset your phone before bringing it in, this will erase all the data. Don't forget to take out your MicroSD if you have one in.

When they take out your sim the phone will not receive calls anymore. If you have another phone, or get a loner, you can put the sim in that one or just have Bell tranfer the phone number to your loaner phone. If no other phone then just an unavailable message or voicemail.

When I took my Vibrant in 'three' times for exchanges the last time was going to be for a while so I bought a used Bell phone for $25. ( kijiji ) and they transferred my number to this new phone until my replacement showed up.

Well, three days now on EDGE only and no lockups, no reboot loops and I notice it no longer randomly loses cellular connectivity.

From my point of view it would now seem every problem I have been having is strictly related to HSDPA.

Quite why is still entirely a mystery.
[Galaxy S I9000 Q&A, Help & Troubleshooting] AllGamer:
there are more 850 coverage than 1900
[Galaxy S I9000 Q&A, Help & Troubleshooting] Lookieloo:
Thanks for the information. Hoping they just put my card into a brand new phone and send it home with my husband. It's really annoying that between Best Buy, Bell, and Samsung, I end up having to wait, or be inconvenienced by a lemon of a phone! And why should we have to pay for a loaner while our dud is in the shop.

I bought Best Buys Exchange/insurance package...now let's see if they honour it. I'd be willing to bet they're gonna tell my husband they haven't got stock in the store. That's exactly what they said when we initially went in last Thursday. That's when we thought it was just the battery wasn't charging. I'll keep you posted.

As an interesting side note...I have NEVER been able to register the phone over Samsung Canada's website. I also can't use the email customer service form. Neither of them work...very odd don't you think? Anyone else had this problem? As soon as you Tick "Mobile" the online forms freeze and wont let you scroll down to the SUBMIT button. I'm getting rather PO'd.

Hello all, my galaxy S is the european version and has the same problem.

I'm not using GPS, WiFi and APN is off and the problem hapens.

I'm afraid it's not SW nor HW issue, it's mechanical. When I opened the back cover I can notice the battery is a little bit loose inside. So I think all we are facing is a bad contact.

I put a small piece of paper to tigh the battery into contacts. I'll post the result sooner.

[Galaxy S I9000 Q&A, Help & Troubleshooting] Keatonm:
Yup, turning the APN off sure does fix it. Hasn't locked up since last posts on Sept 28th. I'm going to try the Voodoo lagfix and see if that helps. Has anyone tried messing with their APN settings? I doubt there is anything that can be done there though.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Fevr:
Just thought I'd chime in on this issue. I'm another Bell SGS user, in Calgary. Phone comas multiple times a day. I'm now using the APN On/Off widget which works fine as a temporary fix. Only had the phone for 2-3 weeks, so I'm waiting to see if it's worth sending the phone back, or if waiting for the software upgrade will do the trick.

I've read the whole thread, and agree with most of the conclusions you have all come to. However, My phone loses signal a LOT, but does not always crash. I've got an app called no signal that runs in the background and logs whenever my phone loses signal, and reconnects. I've even been using it, and seen all the bars disappear, which produces the little circle with the line through it, meaning no signal I assume, and it's been fine. So sure maybe losing signal sometimes causes the coma, but not always.

I am unable to set Combi Bands. The only way my wife's SGS will connect to the cell and data network is to use WCDMA. So I set that to use 850,900, and 1900 bands - but NOT the 2100. When I do a Phone Info (*#*#4636#*#*) the SGS now says WCDMA. Before it said GSM/CDMA Auto. I also noticed it only switches between 1900 Band 2 and 850 Band 5. Before it was all over the place.

These settings are very close to my Hero - so I have my fingers crossed that this will work. Could it be the WCDMA 2100 causing the problems? Perhaps the phone is trying to use the fastest possible connection, but the network architecture is not good enough?

We will test tomorrow in the known coma zone and I will report back.

Over-and-out.
[Galaxy S I9000 Q&A, Help & Troubleshooting] digi-geek:
I see this is still working for you. Questions:

1. Is your phone unlocked or rooted?

2. Is this something we can do with a "standard" Bell SGS?

3. Also curious to know what your phone says under the "*#*#4636#*#*" -->Phone Info...scroll down to "Set preferred network type:"

My Hero shows "WCDMA Preferred". The crashing SGS usually showed "GSM/CDMA Auto". And often times would flip between WCDMA Only and then nothing. And then would flip back to something. Very weird. 3 hours since I did the Network Bands adjustment with no issues. Won't know for sure till tomorrow though...here's hoping....:confused:

Crashes in Germany as well

Since I changed my provider from "Base" to "1und1" (Vodafone network) my phone is crashing every day - before that no crash at all. My conclusion is the same as mentioned here before: the culprit must be the switch between HSDAP and Edge. I walk my dog every day in an area with low reception quality and there my phone always freezes or chrashes. After the crash it takes the phone extremely long to reestablish the data connection. My old provider has very little HSDPA coverage and with 'normal' UMTS and Edge everything seems to be fine.

I'm really stumped, no idea what to do. It still isn't clear if this is a hardware, software or carrier (sim card) failure. My guess is software, but then why is the problem apparent in so many different Android versions? I am running the original Eclair firmware with the Lagfix update...

I think I am going to have the phone replaced even if I am fairly sure the next one will have the same problem.

Cheers from Berlin

Interesting observation, I was toying with this but had nothing to compare with. I do notice something now however:

Ms SGS inside the Settings menu has GSM/WCDMA (auto mode) by default but that when seen in the Test menu (the code) shows GSM/CDMA auto despite WCDMA being an available menu selection. That could be a simple typo in the firmware but I can not actually force it to use WCDMA in Testing.

Possibly not important but in my Milestone I could actually make changes in the Testing menu, here I can not, they reset.

I am on T-Mobile but my tariff is really old, I have unlimited HSDPA but at a staggering 0.33mbps limit, and 0.03mbps upload. So I am sure my specific contract details are somehow involved here.

Ive been having the same issue after just having the phone a little over a week now. I havnt had a crash in bout 2-3 days now after doin 2 things..not sure which one helped.

heres my specs:

PDA: i9000UGJH2

Phone: i9000UGJH2

CSC: i9000MCJH2

Unrooted phone (still not sure what that means)

have not done anything technical with this phone since its been out of the box, no updates nothing. dont know how to do any of that yet...

1. I downloaded Advanced Task Killer off the market cause someone on this thread said it would help. i kill most task after doin anything on the phone especially before letting it go to sleep.

2. I also unchecked "Background Data". Only turn it back on when needed.

To get there: setttings>accounts and sync>background data

Hope this helps anyone! im sorry if this is all for nothing

Observations continued ....

1. Almost 100% sure that phone goes into comma only when APN is enabled. Doesn't happen if you turn off mobile internet using APNDroid.

2. Issue happens when phone tries to automatically switch between 3G/3.5G & Edge/GPRS.

3. No application so far has helped.

4. If I manually select only GSM or Only WCDMA, phone doesn't go into comma. I selected WCDMA only and phone did not go into comma since 24 hours. When on auto, it goes 3 - 4 times daily. Need to test it further. Will keep you guys posted.

5. There is an application on market "2G-3G on off" widget. It allows easy switching between 2G and 3G. If we keep the phone on 2G and only switch to 3G when using internet, we can prevent the phone from going into comma.
[Galaxy S I9000 Q&A, Help & Troubleshooting] fredvermejo:
I'm using Froyo ROM beta (I9000xxJPK) the last one, APN off WiFi and GPS off also and the problem happens.

Some post ago I mentioned the loose battery, but it wasn't the problem, even loose it was connected and I've made some vibration tests.

Digging deeper, I've realized that it only happens to me ( I don't know about you) when battery charge is bellow ~40 ~30% and when I restart the phone the battery shows 50% or more. So I'm almost convinced It's a bug on battery management and it's dependent to kernel modules.

I think somehow the power management "thinks" the battery is "empty" and shuts down the phone.

Keeping battery above 60% charged my phone never shuts off.

Hope this info is useful.

It's good that more people are trying to help work this out but if you read back through the thread you will see this is all established, you could of saved yourself time finding those things out.

Rooting the phone means to have root access. That is to say you have full administrator control which is usually - on a phone - reserved for system control. So I am unsure how you unrooted it if you applied no modifications as to root a device is a process you would of had to do in the first place.

Unchecking background data is effectively the same as when people mention disabling the APN in this case except that disabling background sync will still allow you network access if you ask it do do something where APN is full disconnection from cellular data.
[Galaxy S I9000 Q&A, Help & Troubleshooting] nailerr:
I'd had a similar thought earlier in this thread, SystemPanel shows that my power takes random and violent dips and Samsung UK phone support suggested the PMU was not correct. However since then I am less sure how accurate SystemPanel is, as it may just be inconsistency in monitoring frequency.

On the other side my phone is more often than not over 70%.

The phone however is not off, that I can tell because an off phone will boot when the power button is held for a second or two where as in the "coma state" it requires something around 10 seconds which would appear to be a forced reboot. If so, the phone is on - just not working, which is why I initially called it comatose. The OP asked why his phone turns off but it would seem that in most cases it is not actually off, as said.

That you have APN off and still have issues on 2.2 is worrying though, unless you are coincidentally having other problems that only seem the same as those in here? I just want a damn phone that works!
[Galaxy S I9000 Q&A, Help & Troubleshooting] digi-geek:
Same thing happened to me - it was driving me crazy. You have to make the change in the service mode. When I did that - it would finally stay.

Something new we noticed was that our signal will go from 3G...to H... and now completely drop off. Then suddenly come back with H. Eventually 3G/H flipping....and then drop off again. Repeatedly. Seems to support the Edge/HSDPA theory.

No coma in coma zone yet....stay tuned.

Bad news. Coma. I had it set to use 850,900,1900 bands. Maybe I'll set it to only use the 850 and 900 and try again tomorrow.

One more thing I've been wondering about is the inconsistency of the connection. I have never noticed my Hero show any signs of switching or losing data. Yet this SGS is constantly flipping from 3G to H - and sometimes completely dropping off.

Maybe it has nothing to do with the actual bands, but the constant SWITCHING. Why can't it get a consistent lock and stay connected? I can understand the constant switching if the phone is in a car or mobile in some way. But, if its just sitting in one place - why is it constantly switching bands? I feel like we're going in complete circles here. Hardware - software - network - chicken - egg. Ugh.

Hey guys.. I've been following this thread closely since I'm still waiting to jump back into a SGS or SGS-like android device.. as some of you know I ended up DOA'ing my second SGS for the BB Torch earlier this week.

I don't know if there's a hardware issue for the SGS, but with the BB Torch in my office I've found that the BB doesn't jump from no 3G to 3G like my 2 SGSs did.. I've had it for a few days in the office now and I haven't had any issues with getting/keeping 3G, whereas on the SGS, it was constantly 3G/H/Nothing, like as if it was a slot machine.

So perhaps it could POSSIBLY be an issue where the SGS isn't as good when it comes to acquiring/holding a 3G signal?
[Galaxy S I9000 Q&A, Help & Troubleshooting] nailerr:
I had actually always assumed that the flicking from H to 3G was simply because HSU/DPA is a superset of 3G tech. Is anyone sure it its really actually flicking between bands and not just being overly assuring that we are on 3G?
