[Galaxy S I9000 Q&A, Help & Troubleshooting] nailerr:
I use a monitor called SystemPanel which tracks the phone use and state over a week with graphed data, one thing I noticed over the last few weeks was that my battery graph will on occasion take a sudden dip, say from 90% to 30% then back up again. This does not always result in a problem on the phone but I think it does always preceded a crash or reboot when one happens.

Is perhaps the power management on some of the phones stuffed? I imagine it can withstand a power dip, but lets say perhaps sometimes it dips to zero and back sometimes causing the phone to flip out a bit.

I have my second SGS now, the first was from UK this is apparently Portuguese, and my friend has a German one all having crashing and rebooting issues. We know a third person with a German (I think) one and he has had no issues at all.

I am running JM1, which my UK one installed fine but this second one required Kies in test mode to force it.

I have this same issue too! At first it hanged en didn't respond (getting warm too) and I sent it off for repair and they took 2 weeks... just to upgrade the damn firmware! Prob seemed fixed untill another problem appeared! when I put my sgs to charge and use it at the same time it will shut itself down and try to reboot but will hang on first screen of boot or later if it passes that! I noticed that letting it cool down helps also!

Yesterday my phone restarts on its own, does not switch off as well..

When I do a check later on, I find:

"Settings -> About phone -> Battery use:

Battery 6 min since unplugged" <== When the phone restarts itself 6 min ago

& at the same time

"Settings -> About phone -> Status ->

Up Time : 38 hours" <== when I actually turned on the phone myself

I am confused.

Another user with the same issue.

Same issue with my Vibrant. First time this happened, I was at my friend's appartment (this was a Friday evening). It happened about 5 times while I was there. The next day (Saturday), it happened twice at a different location. On Sunday evening, my battery was drained so I charged it and unplugged it when the phone notified me that it was full. When I woke up Monday morning, it was in the same state but this time when I held the power button for 10 seconds to restart it, the phone came back on and the battery was fully drained again. I called Samsung support and was notified that this issue was due to the battery. I was told to go to a Bell store and they would use the ticket number I was given to get a new battery. Unfortunately, Bell does not yet have any accesories for the Vibrant (batteries included) so I have not yet been able to swap it. I seriously doubt that it has anything to do with the battery and I am leaning towards it being something to do with location. I have no issues when I bring the phone to work with me in Halifax and the night that the battery drained itself, I had the phone on my nightstand in the bedroom where I have poor reception no matter what phone. I will bring the phone back to my friend's apartment to see if the issue replicates.

Hang on a tic, a few posts ago I mentioned how before every crash SystemPanel recorded a massive dip in the battery power on my i9000, that sounds somewhat connected... Perhaps? I had previously also thought location awareness was key but others have had the problem with all location awareness of the device turned off.

And it is exactly the same problem I am having, the comatose phone, not off but not on, needing a ten second button reboot..
[Galaxy S I9000 Q&A, Help & Troubleshooting] TheChancellor:
Well, this is just a hunch... But I think this shutting down thing is GPS related. Someone said in an earlier post that he encountered less shut-offs when he got rid of latitude and a weather widget {which could have also been using GPS}. Also, today when I was going for a run, my phone literally just shut off while using Endomondo {an app to track my distance}. Mind you, the GPS tracked my route perfectly. I'm just thinking that maybe there's more to the GPS issues.

Or.... I'm a total idiot for even assuming that this is caused by the GPS. But I can't help but think these shut-off problems are related to the GPS.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Cruisin1966:
I've never used the GPS and have had multiple lockups/sleeps while in the office (poor reception). I have also never had the phone act funny outside of the office.
[Galaxy S I9000 Q&A, Help & Troubleshooting] greendot1:
Do you have GPS disabled, or do you just not use it actively?
[Galaxy S I9000 Q&A, Help & Troubleshooting] Cruisin1966:
Disabled. I have no use for GPS at the moment
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJNutty:
Has anybody here tried sending a link to this topic to Samsung tech dept? I think they need to be aware of this and that it is not an isolated incident. The second rep I spoke to told me it is not a battery issue and that my phone must be returned to Samsung as it is defective. I have read a few posts on this topic stating that some people are on their 2nd or 3rd device. Seems pretty unlikely to me that one person could get 3 defective phones and this points (to me at least) that it is not hardware related. I do not want to send my phone for repair and end up with a refurb. Also, I forgot to mention that I made it through a week with no comas and then went to Walmart the following Saturday and bang...coma.

UPDATE: I just finished emailing Samsung and included the topic link.
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJNutty:
PS: GPS was disabled during all of my phone's comas. I make sure I turn it off when I'm not using it to save battery.

Mine came with JH2 out of the box and I have had it for about 30 days. I have not had one issue with it.. It also had the 3 button combo working out of the box as well.
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJNutty:
So what is it you are trying to tell us? Take ours back? You haven't left the Bell store with it yet? How does your Vibrant not having this issue help us?
[Galaxy S I9000 Q&A, Help & Troubleshooting] gwwaters:
Yowza, keep an open mind!

Perhaps I shouldn't tell you that since I downgraded from JM8 to JH2 I have not had a single black screen. The downgrade was 5 days ago. Perhaps firmware version has something to do with this.

Personally I am convinced that location has something to do with this. But I can't prove anything.
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJNutty:
I think you're right about the location being the issue. Actually, to be more specific, it is all being caused by low signal. I hope Froyo addresses this issue for us! Check out this link: facebook.com/samsungmobilecanada[/url] (scroll down to Cat Charman's post and read replies). I'm not sure where they got this info (yet).
[Galaxy S I9000 Q&A, Help & Troubleshooting] TriC_101:
Geezz... Chill...

I was giving my info so that people can compare combinations of firmware and 3 button combo. and build date since its likely a software issue.

I have a friend that had the same issue and he re-flashed JH2 and its fine now.. he was running JH2 before but when he re flashed it with the 3 button combo fix update of JH2 he has not had the issue since then. Before it would reboot twice a day.
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJNutty:
I am using JH2 as well...

Sorry for the sarcasm earlier but I thought you were just posting to rub in how your phone works perfectly and mocking those of with this issue. Again, sorry.

From what I have just read (see link in my post above), the phone is locking up because of low signal and something in the phone not liking the low signal.
[Galaxy S I9000 Q&A, Help & Troubleshooting] TriC_101:
No Prob..

I think it might be more then that.. since the Samsung S that had the issues would reboot when mine would not and the signal strengths were the same on both phone since we were in the same room.. I wonder if anyone else has re-flashed JH2 and if they have not seen reboots after the flash.

just had a few questions...

Have you tried any other firmwares??

also have you tried formatting the internal SD card?

the last question did your 3 button combo work out of the box?
[Galaxy S I9000 Q&A, Help & Troubleshooting] JJNutty:
I have not tried any other firmwares. I have not tried formatting the internal SD card. My phone came out of the box with JH2 and the 3 button combo worked out of the box.

Just another Bell Canada user experiencing the same problem with my Samsung Galaxy S Vibrant.

Purchased August 17, 2010.

Ran JG9 firmware for 1st week. No issues with freezing.

Upgraded to JH2. No issues with freezing until September 14, 2010.

Summary of freezing:

Froze 1 time on September 14, 2010

Froze 1 time on September 15, 2010

Froze 6 times on September 16, 2010

Froze 5 times on September 17, 2010

Froze 2 times on September 18, 2010

Froze 3 times on September 19, 2010

Froze 5 times on September 20, 2010

Froze 6 times on September 21, 2010

Froze 1 times on September 22, 2010

So far today the phone has had nearly 11 hours of uptime. :eek:

(It appears everytime you restart your phone a new log file is created in the /z7logs/ directory....not sure if this directory is related to an App I downloaded or if it is found on all installs of this phone.)

Here is what I've observed with the freezing:

1) It occurs most frequently in areas of poor signal strength. In my case this the basement of my house. I do find it rather odd that during the first three weeks of ownership I had no freezing problems, even though I spent just as much time in basement.

2) The phone is still working....it just won't respond to any button inputs. I know this as I was listening to the radio when the phone became unresponsive. The radio was still playing even though the phone wouldn't wake up.

3) The phone started having issues after I had gotten a number of new apps. The app that I am most suspect about is the full version of "Robo Defense" .

4) I did manage to catch the phone one-time running extremely sluggish....I think I may have caught it on the brink of going comatose. A reboot of the phone solved this sluggish response problem. I am by no means an authority on Android architecture.....but I am suspecting that a program on the phone has a memory leak.

Other Random thoughts

It appears this issue is happening more on phones with Bell Canada. Could there be a glitch with the Canadian firmware? From what I've read on other posts, the JH2 firmware was released twice in Canada. The second release fixed the 3-button combo problem that some were experiencing. Accoring to the following thread this fix was only released in Canada....but Richofen has made this fix available to everyone. Here is the thread on the 3-button fix. (Can't put the whole URL in as I am new user :mad:)

xdaforums.com/showthread.php?t=785201

If each country/service provider is getting their own firmware....then maybe there are some bugs in it. (Bell Canada users get their phone installed with Bell PVR Remote, Bell Tunes & Apps, Bell TV & Radio)

Has anyone in Canada tried rooting their phone and installing different firmware versions?

I have rooted mine and have tried different firmwares (JP1 and JP3) i'm back to JH2 but I don't have the reboot issue with my phone... to tell you the truth.. JH2 seems to be the most stable out of the firmwares I have tried.
[Galaxy S I9000 Q&A, Help & Troubleshooting] nailerr:
I am convinced signal is not an issue at all, just coincidence. I work 6 day s a week in a room that is almost shielded from outside radio. So for as many as 70 hours a week my phone is in a room where I have to keep waving it around to find todays best spot for a single bar reception phone call. It has not once crashed while at work.

It has however crashed nearly every third bike journey to or from work where I pass multiple cellular towers and have really good signal. I am in a business city in Germany near Frankfurt, the places it has crashed or frozen have all been over 80% strength UMTS with no problem falling onto equally strong EDGE if I turn it off.

All I can say is moving about is more certain to kill it which is why I believed until recently that cell tower handover causing the modem to wake up and attempt to update the devices location by CELLULAR WIRELESS location (not wifi) to be a large part of it. After-all Google DO warn you that if checked in settings they will collect location info even if no program on your phone asks for it. This is still location awareness but without the use of GPS.

However. It has been crashing and rebooting like crazy this week and I have been sitting in one place, high signal area with location off. So...

UPDATE: I placed my phone on the nightstand in my bedroom again last night and it fell into a coma again.

Some more info about my phone:

Bell Vibrant purchased Sept. 8th

PDA: I9000UGJH2

PHONE: I9000UGJH2

CSC: I9000BMCJH2

Stock, Not rooted.

Unlocked and being used on Telus

Here's what else I have found out over the last day of testing:

I downloaded an app called APN OnOff by Curvefish.

This gives you an ON/OFF widget - when APN is set to OFF, it disables Cellular data. When I have APN set to OFF - the phone does NOT go into comas.

So far I only have the last 24 hours to go by.

When I'm at home and work I have wi-fi anyways, so having apn OFF doesn't affect me. When I'm out, I can still make calls and text with APN set to OFF, but when I need to use data or GPS I have to turn the widget on. Today I needed to use twitter while I was at a restaurant, so I turned APN back on, and within an hour phone went comatose.

Anyhow, those are my initial anecdotal findings. I'm curious to see if others see the same thing. I hope this helps in narrowing down where the problem is.
[Galaxy S I9000 Q&A, Help & Troubleshooting] nailerr:
Well Samsung UK support said something this time that sort of made sense, that they think there is a power related problem inside the device. This at least correlates to my SystemPanel log where the battery randomly and frequently shows it down to close to 0% then back up to whatever it was before.

I asked how realistic this is given my first broken one came from the UK (according to the product code) and the second from Portugal (TPH). He said they are mass produced and shipped out, so it is entirely possible I have two from the same batch despite the geographical destination.

I'm kind of angry now, I have to ship back a third phone and who knows if the next one is a newer unit?
[Galaxy S I9000 Q&A, Help & Troubleshooting] thegandalf:
I am experiencing the same Sleep of Death symptoms.

But I am not sure if it is related to an app (not rooted, T-Mobile Germany Stock Rom, maybe AppKiller?) or Hardware.

Also the signal strentgh is highly variable. Sometimes drops even to 0.

Here too it might be an optimization to conserve battery time.

I am loosing patience with this phone. Do you guys think a custum Rom would fix the problems?

My Versions:

I did not keep track but I had to "reload" about three times in three days.

AutoKill was enabled with the AppKiller. I now will test it without the auto kill feature.

If it will happen once again I guess I will bring it in.
[Galaxy S I9000 Q&A, Help & Troubleshooting] TheChancellor:
Interesting... you know, maybe we have to do a battery reset? There are some instructions on this forum somewhere about how to do that. Maybe that'll give us a more consistent reading? I don't know, just a theory.

Something else I found interesting was that since flashing the new JPK firmware, I haven't had my phone shutdown in the same manner... YET. I'll keep you guys posted.
[Galaxy S I9000 Q&A, Help & Troubleshooting] nailerr:
Today I called Samsung Mobile UK and asked what are the chances that my first unit from the UK and the second from Portugal AND my friends from Germany all have the same hardware fault (bad batch) and was told "quite likely" as they manufacture many at once and send them off around the globe. (As they said before)

They advise I find a Samsung tech centre and send it there rather than ship back to the store as it will be checked out by technicians where as the shop may have many bad phones.

I really do not know, and I am sick of this situation but if 2.2 is not so far off I am planning to wait and see. I am tired of sending phones back, it's expensive.

Got a new SIM today from T-Mobile, not solved anything.

I too am a Bell Canada user, and my story is almost identical to yours. I bought my phone on launch day here, Aug 6. I updated to JH2 the day it was released, I don't remember when that was, but it was late august maybe? My phone only started freezing THE WEEK OF Sept 14.

I hadn't installed any new apps or anything that day. I had read somewhere if its an overheating issue it could be a skin or something put on the phone. That was about the time that Bell (in Calgary) got the skins in stock and I put one on, but I'm sceptical that has anything to do with it.

My phone problem is just like many others here where it goes "comatose", I've had it happen twice with the screen on, and thats what made me google "freezing" instead of "shutting off" and found the 10 second reboot method. Previously I'd had to pull the battery.

Just wanted to add another number to the pile for stats purposes. :rolleyes:
[Galaxy S I9000 Q&A, Help & Troubleshooting] greendot1:
That's interesting, I got my phone Aug 27 and it came stock with JH2, but oddly enough just like you I didn't have any issues with freezing until mid-last week (around Sept 15)

One of the people I know with a perectly fine i9000 has had his phone hit 60c heatwise, and it is yet to be worse for it. Heat would probably have a lot more complaints too because google navigation bakes these things.
[Galaxy S I9000 Q&A, Help & Troubleshooting] AllGamer:
60c it's pretty scary temperature when i had it on my hands, if it were not by the 2 layer of cases, i would have probably burned my hand.

last time my phone hit 60c i quickly turned off WiFi, GPS, BT and unplugged the charger

i was using the phone with the OEM battery being charged when i was doing a lot of webbing in the phone via WiFi, BT and GPS was on with CoPilot running behind, cuz i like to be able to quickly switch back to the GPS software as soon as i head out of the office/house

i never had that heat problem before when NOT charging the phone. (GPS, BT, WiFi all ON)

anyways since that time, i stopped charging the phone with all the features on, it causes way too much heat.

using the phone internet via 3G + BT + GPS On meanwhile charging does not causes the heat problem, it's weird seems to only happen with WiFi
[Galaxy S I9000 Q&A, Help & Troubleshooting] nailerr:
Thats not too unbelievable, the Airport card in my imac gets close to 60c with only minimal I/O, under heavy load it gets hotter. Just seems to be a byproduct of wifi.

I am starting to try to come to terms with the likely situation of me (and probably everyone) sending in their handsets to be replaced with refurbs or at least changed in some way. There are so many combinations of events in this thread it is becoming hard to believe it could be software at all, whatever it turns out to actually be.

Just for the sake of it though I am using the APF Off widget mentioned earlier, I'll try and give it a day with as little data over cell as possible.
[Galaxy S I9000 Q&A, Help & Troubleshooting] AllGamer:
yep by all means if some bugs becomes a problem the best way is to send it back to samsung/bell so that they can study the problem and produce a fix

if we end up fixing everythig on our own, their Tech guys will never improve the software/hardware bug associated with the phone.

does anyone installed Froyo 2.2 on his SGS and get/didnt get the problem ?
[Galaxy S I9000 Q&A, Help & Troubleshooting] Modified_Grays:
Thanks for tip. Phone has gone Comatose 8 times today....even had it freeze up with the screen on.

I've installed APN OnOff by Curvefish, we'll see how the phone behaves over the weekend.

Another random observation.....I've found that if the phone goes into a coma while charging.....the phone stops charging.

I agree with AllGamer, that it would be probably best to ship the phones back to Bell/Samsung so they can further diagnose the problem and get a proper fix. My reluctance in doing so is:

1) I've read numerous other posts where Samsung/Bell won't acknowledge that this is a problem. (What we really need is a bunch of momentum to turn this into the next "Antenna Gate" :D)

2) I am quite annoyed by the fact that this issue began after 30 days with the phone, so I can no longer exchange the phone, I must send it away for 3+ weeks to have it repaired. Tough to repair a problem if they don't acknowledge its existance.

3) Several people have posted that they've exchanged their phones 2-3 times, and still they have the problem.

So as it currently stands from my end.....sending my phone gets me the following:

1) 3+ weeks with no use of my Smart Phone.

2) I still get to pay for my data plan, even though I don't have the phone.

3) I get get to pay for a crappy loaner phone.

4) The phone I get back will still have the problem.

In the meantime, I'll try out the APN On/Off, and start looking for a cheap unlocked Smart Phone (for when I do finally have to send my SGS in).
