At first I thought this 850 lock wasn't working for me, but it turned out to be the same problem you are having. Keep fiddling with it, try exiting the menus different ways (don't just push the back arrow, but press menu and exit that way).

For good measure I chose "combi bands" and put the GSM on 850 too, but I don't know if that is necessary. My phone hasn't had a coma in over a month, with no noticeable loss in performance. (Calgary)

For those in the Vancouver area.

I took my phone to the Bell store on Marine Way and Byrne Road, and the guy there said it had something to do with Bell and Telus sharing towers. He then took my phone entered some weird code #*#* followed by some numbers and it allowed him to change some network settings. After that my phone hasnt shut down once and my battery can go 2-3 days now without needing a charge.

Im thinking that my battery was getting sucked dry constantly bouncing back between towers trying to find the best signal.
[Galaxy S I9000 Q&A, Help & Troubleshooting] heythatsmygoat:
thanks guy! any chance you know what he did or can call him and find out to save me driving across town?
[Galaxy S I9000 Q&A, Help & Troubleshooting] fade496:
Pretty sure that it isn't that telus and bell share towers. I think it has to do with the phone's weak signal error handling. When you force the phone to a lower frequency you actually improve your signal. That's why the problem is happening in other countries also.

In my office where I used to coma all the time I forced my phone to 1900 and checked the signal, not just the bars. I had -111 dbms with 1 asu. Then I tried it again with 850. I got -105 dbms with 4 asu's. Considering approx 3dbms is about twice the power I get a way better signal when I force it down to 850, and therefore get less comas.

So why does it happen more out west? Well since the population out west are far more spread out, the towers need to be further apart. 850 travels further without the signal degrading as much.

For other countries, just pick the lowest available frequency.

As for how to do it, I installed SGS tools from the market. It has all the samsung secret codes preprogrammed. That way you don't have to remember the number sequence to type into the dialer to lock is frequency.

Ok so here's another Vancouver story.

I got my phone October 1st... yay! But about a week ago I was experiencing the comatose syndrome, it all started after I tried to connect with the Kies and it shut my phone down. After that it all went down hill and even started to kill my battery in about half a day with just having it in my pocket. I didn't know about the 10 second reset with holding the power button. Was pulling the battery all the time. After going to the pub and it shutting down about a dozen times, I took it to the Bell store to get my 60 day DOA warranty... btw, this does exsist as I saw the guy pull it up on their company e-mails.

So here I am 3 days in with a new phone... it shut off once, while in my pocket at the pub again (while trying to get a girls phone number, embarassing). Hasn't since till this morning when I needed to charge my phone and I threw it on and went to check up on it like a babysitter and it was off. WTF!!!

Well since the new phone I've only installed an update for google maps, Battery Minder, and Angry Birds... just to see what was eating my battery and/or shutting it down. I haven't done the 850Mhz band lock on the new phone, but on the first phone I did it and didn't fix it.

I was also wondering if the comatose problem could be due to the phone temperature getting too high?... well until it reaches whatever it's set to and it shuts the phone down so that it doesn't burn up. Just like a computer does when your CPU fan dies and it shuts down so that it doesn't fry? I don't know if that's possible but just throwing that out there... my first phone had a problem with the phone getting really hot.

App was NOT causing the issue

Somewhere earlier in this post I wrote that I disabled the App "Timeriffic" and coma went away. Well, I was wrong. I coincidentially wasnt just visiting places with UMTS coverage, when I did on Saturday my phone went coma...

Wow, I'm glad some people are open to new ideas and think only inside the box. Also, some people might want to re-read what I wrote and it will show that my first phone did have the 850 bank lock, and it still DID NOT work... so there, that is why I speculated on other things.
[Galaxy S I9000 Q&A, Help & Troubleshooting] border43:
After I update my phone to 2.2 as soon as its out (next week???) am I going to have to do the 850 band lock again? Or will it still be locked after the kies update?

Also, do I need to lock the bands again after updating to 2.2? Or has this issue been resolved in the new official firmware release? Maybe the phone will operate normally without locking the bands after 2.2?

Thanks for any information from anyone who has received the update prior to western Canada.

Bell "fix"

I was in the market mall Bell store today (Calgary) trying to pry hints about a Canadian Froyo release, and the guy said they (that store) JUST got a fix for the freezing yesterday -- sure enough, the 850 band lock. He was surprised that I'd had it for about a month already. It seems this work around is the "official" answer for now.

No word on the froyo release. :S

I'm getting the same error with my new Galaxy S.

It happened when I was trying to play FLAC audiofiles from the musicplayer. The screen went all black and I had to force it to reboot.

I've formatted my SD-cards and removed all downloaded apps. With the default apps, Im unable to reproduce the error by opening alot of them.

The external SD-card was formatted using Windows 7 when this first occured, it's now formatted using the phone. No idea if it makes a difference.

Anyone able to reproduce my experience? Play FLAC using the builtin musicplayer.

I had the same problem with 3 phones, until i got a new sim card from Bell Store (bought my phone originally from BestBuy) I don't know if it was the sim card or what, but its been over 3 weeks without any turns offs, and it was happening every 3 days before that. Maybe, there are bad batches of sim cards out there? I would try a new sim card at a different location, and make sure its a new batch. Also, when i used to have this problem, it only happened in area of low reception signal.(actually it only happened at work every time...never at home, or anywhere else)

Try new firmware update

Hi all, just started getting this issue.

Provider: Bell

Phone: GT-I9000M

Firmware: 2.1-update1

Build number: ECLAIR.UGJH2

Kernel: 2.6.29

Notes: Unlocked and Rooted

This is my personal phone. So far only has happened when battery is below 20% and in an area with really crappy/no reception (at work).

I have a Rogers SIM card (work phone) I'm going to try in the phone as well. Rogers has better reception at work so I will do some experiments and report back.

From what I've read, I believe there is a newer update in Kies that should remedy this issue (according to some user reports).

HI All,

I have my SGS for just over a month and started having problem about 3 weeks after I've got. I did the upgrade firmware but the problem continued.. lately it seems to get worse. Today is crash 5 times.. really frustrating... I took to the Bell store and I would need to send it to Samsung for repairs.. They said that Samsung does not identify this as a problem.. I noticed that it always happens when connectivity is weak.. I have reset today and hope it gets better but I am not confident.. I am hopping Froyo will fix this issue.

I noticed the reception in this phone is always poor.. 3g and Wifi.. Wifi at home is always only 1 bar or out of range, even sitting next to the wireless router...

Anyhow.. I will post if I find anything that seems to fix it. Please do likewise..

thanks,

Same thing here, have an EU spec i9000 on T-Mobile (via Mobicom Debitel) and since day one it's been randomly turning itself off. On the way home from work on the train it usually does it at a very specific location. Screen goes black and it has to be reset.

I think it's either a SIM card or signal problem as all I've done so far is rooted and installed lag fix. It was switching off even before I'd applied any fixes. It's really frustrating, what with the crappy GPS and the wobbly compass. Apart from that I love it.

Come on Samsung, fix the problems and roll out Froyo!

I put in a sim card and my phone worked great for 3 weeks...no more turn offs. I also didn't use adobe reader for the 3 weeks, because i heard someone say on another forum that this could be the problem.

It's happening to me all the time. Just happened to me a few minutes ago. I was going to take it in to Bell, but there was no way to actually "trigger" the bug so I didn't think I'd have a case. I've just went over the 30 days so it looks like I'm gonna have to hang onto this dud until Froyo comes out. Here's hoping guys.
[Galaxy S I9000 Q&A, Help & Troubleshooting] border43:
I read that somewhere too, so I tested it out. Turned off my live wal paper, and it did not fix the problem. It still turns off all on its own, many times a day.

If froyo does not come out in a week, then I am returning my phone for a 3rd one. Maybe third times the charm, and it will finally work. But I hope that froyo comes out before my 30 days are up with Bell, and that it fixes the problem.

I told myself I was never going to buy another Samsung phone after my last "Smartphone" - the samsung instinct. Biggest POS ever. Now the galaxy S came out. Looked amazing - nope. Can not rely on it to ever be on, so I need to constantly check it to make sure I am not missing any calls or anything.

I keep getting random reboots and all the theories that people are talking about in here don't apply. Wifi, weak cell signals etc, certain apps... nah... I have no idea on the cause but I know its not what a lot of people are hinting at.. probably crap firmware releases really.

When i say random I mean every 2-3 days the phone will just reboot basicaly, its not a killer thing but its kind of like going back to windows 98....

Same Issue as all these posts...

Hi, I have had the same issue for the past 2 weeks, so frustrated I almost threw the phone up against the wall...LOL. I factory reset so many times and reconfigured from scratch..nothing worked. Called the Bell technical support who said oh, never heard of that issue...LOL, you need to send it in for warranty which could take 4-6 weeks!! So I went to the Bell repair centre and was informed that even the manager of the center had the issue and they were advising folks that 2 updates are coming out this week. 1 to fix the crashing and the other to upgrade to Froyo, so they said don't send it in and check back with us this week for the update instructions...heres hoping that works! :rolleyes:

[Galaxy S I9000 Q&A, Help & Troubleshooting] hirosa:
So is it fair to assume that Froyo fixes the phone switching itself off (ie. leaving it by your bedside while charging) and that there is a problem with certain apps/games that cause it to crash?
[Galaxy S I9000 Q&A, Help & Troubleshooting] Bjohansen:
I'm fairly new to Galaxy S and Android as I got my phone yesterday, so I won't jump to any conclusions.

I think it's kinda sad that the builtin musicplayer might be the source of my phone's black outs.

The first black out happened yesterday when I wen't to bed. The second I turned the lights off, the screen went completely black.

Should I go to the store and get a new one?

Edit: I think I've figured out why my phone were freezing. The memory card might have been corrupt or even the wrong filesystem which crashed the phone when it tried to read the files via the musicplayer.

I've formatted the memory card from within the phone and also done a factory reset, it's all good now :)

UPDATE

Hey,

So I've received an e-mail from Samsung in regards to the 850 Band Lock & the Froyo Update. I ended up pasting a solution posted earlier, and posting the reference to this forum.

So far, my phone hasn't frozen since.

Good afternoon Nicholas,

Great job on successfully activating the band lock, we're aware this is only the temporary solution but nonetheless we don't anticipate you encountering the freezing up issues you've experienced thus far. In regards to Froyo 2.2.inquiry, no official release date for the Canadian market has been provided. ‘Word on the leak’ is; we can expect Froyo2.2 as early as the end of November to mid December just in time for Christmas, but again no promises.

Everyone who upgraded to froyo has reported that comas went away. There have been no reports to the contrary not have there been any reports of having to lock to 850 mhz only.

This is a solved issue. Upgrade to froyo and put it behind you.

My problem of losing signal on froyo on an international i9000 supporting 1800mhz only appears to have been related to the froyo rom version I was running.
