[Captivate Q&A, Help & Troubleshooting] jsouza1:
I think I've found a solution

I think I've found a solution, one that works for me anyway. YMMV. I have found that if I disable the display power saving mode (Settings->Sound and display->Power saving mode), then the problem does not occur. With that setting disabled (unchecked), I can leave my phone sitting idle on my desk for over an hour without it automatically shutting down. I was not able to do this yesterday before I found this setting. I'd be curious to know if this also works for anyone else besides myself.

(This was also cross-posted on the AT&T forums).
[Captivate Q&A, Help & Troubleshooting] checkers2884:
Nice! Let us know if this keeps working for you. Hopefully it will and Samsung can properly address the issue in an update along with the GPS problem. I REALLY hope they do fix this because this phone is freakin' sweet! I don't want to have to switch to something of a lesser android phone. They're few and far between on at&t anyways.
[Captivate Q&A, Help & Troubleshooting] vksf01:
so i'm getting my phone back from samsung after sending it back for the shutdown issue. i don't think i'm getting another one though. this is what they sent me as their diagnosis

Original Problem:

Technical Inquiry

Power

Power Up Then Down

Problem found:

LOCK UP DURING OPERATION (SW)

SW,PRL,OTSL RESET

Solution:

Passed All Functional Testing

anyone knows what "Lock Up During Operation (SW)" means?
[Captivate Q&A, Help & Troubleshooting] heygrl:
SW?=Software? Makes more sense to me than anything else considering the fact that the Vibrant doesn't have this problem.
[Captivate Q&A, Help & Troubleshooting] vksf01:
that's what i suspect too, however, i'm wondering what this "lock-up" is. oh well, i haven't got the phone back yet, but hopefully whatever they did (which seems to be some kind of reset) fixes it. if not, i'll have to keep bugging samsung
[Captivate Q&A, Help & Troubleshooting] swarlos86:
"SW means software, PRL means preferred roaming list, and OTSL means One Time Subsidy Lock. I’m not sure what Samsung thinks these have to do with a blank screen since these items usually affect things like dropped calls and call quality (hearing static, echo, etc.)."

Got this off of another forum. Seems like this is just how samsung fixes all their defective phones. This person in particular had his screen go out, and they sent him a new one with the same "problem found" and solution listing you got.

According to the log i guess a software, PRL, and OTSL reset does the trick for a lot of issues. So maybe not a hardware issue as people say? Not arguing this, just reading what the log says.
[Captivate Q&A, Help & Troubleshooting] vksf01:
Bizarre...oh well, I'll see how the phone acts when I get it back, and if it continues shutting down, i'll continue hounding samsung until they fix it
[Captivate Q&A, Help & Troubleshooting] gordec:
So anyone has working solution for the shut downs after Cappy is charged? I am pretty sure it's the OTA update since before it never did shut downs now it shuts down everytime after a full charge. It never had any issues when off the charger.
[Captivate Q&A, Help & Troubleshooting] genem1:
While my shutdown events have been infrequent (3 episodes since a 7/30 purchase), I have been unsuccessful in trying to reproduce this problem since the recent update (GPS fix, QuickOffice, etc). I always charge to 100%, clear the dialog box, turn off the screen, let it sit. No problem yet.
[Captivate Q&A, Help & Troubleshooting] captivating:
I had the same issue with my captivate shutting down everyday after a full charge. It would shut down 5-10 times until the battery drained a little. I tried all of the power managment tips in this thread, no luck. This went on for about 2 weeks.

I ran the unleash the beast tool and it still shut down. Finally after flashing unhelpfuls kernal v1.2 the problem went away 100%. I haven't had a shutdown since Sept 3. This worked for me, hopefully someone else can try to see it if works their their phone.
[Captivate Q&A, Help & Troubleshooting] Belaflek:
Im on my second replacement that will be sent back next week. Seems to play nice through the day but when I go to sleep, off the charger, I wake up and its off...not only that...it shuts itself down like 2-3 times in the morning afterwards. The only thing that has changed is its gotten colder and ive not turned on the heat so Im waking up to a 68-70 degree house. Never rooted. O well...letstalk.com only allows three exchanges and Ill go with the AT&T refurb if the next phone does it. If there was only a way to keep logs wih like a 1mb buffer so it will have some 411 when ya boot up as to what it was doing before it shutdown.
[Captivate Q&A, Help & Troubleshooting] klcross87:
Just had my first random shut down yesterday, thought I was one of the lucky ones. Guess I will be reading thru this thread when I have some time.
[Captivate Q&A, Help & Troubleshooting] Foxman13:
I flashed the latest Cognition ROM Monday night and haven't had any shutdowns yet with at least 3 full charges since then. I will keep an eye on it over the next few days, but looking good so far.
[Captivate Q&A, Help & Troubleshooting] shutterbc:
Is there any further evidence that the issue is temperature related? I think I only had this happen once, and it was when I was charging from a computer in a poor reception area where the internal temperature may have approached 100+F. Haven't had a single problem since.
[Captivate Q&A, Help & Troubleshooting] Belaflek:
nah..no evidence..just anecdotal
[Captivate Q&A, Help & Troubleshooting] phr00t:
I got a replacement phone a few days ago because my search button was randomly being pressed...

Now I have the shutdown problem with this "refurb" phone. Ugh.

The thing has shutdown 3 times since yesterday. I pick up the phone, and I have to turn it on. I assume I just need to get another replacement? :rolleyes:
[Captivate Q&A, Help & Troubleshooting] gordec:
Flashed to cognition 2.1.4. Still getting shut downs after full charge. I am beginning to think has something to do with the OTA even though I know many people with OTA don't have shut downs. I may flash back to stock see what it does.
[Captivate Q&A, Help & Troubleshooting] benjer712:
I am currently on my 3rd captivate with my 4th warranty replacement from att in the mail. All 3 have randomly shut off whether stock or on designgears Tom. I'm hoping the 4th one works, but if it doesn't I'm selling it and getting a different phone. The captivate has great potential but too many issues to be a reliable everyday device.
[Captivate Q&A, Help & Troubleshooting] Foxman13:
Just had my first shutdown this morning running Cognition ROM. There goes that theory! Guess I will be swapping it out this weekend.
[Captivate Q&A, Help & Troubleshooting] kiltedthrower:
Okay. How do I remove everything off my phone down to stock?

And when I get my new phone, do I just go back to the market and it'll recognize what I've purchased previously?

My shutdowns only occur at night when I'm not using it for an extended length of time. Hopefully the second one will be better. I don't want to wait until it's shutting down during the day and not just at night when I'm sleeping.
[Captivate Q&A, Help & Troubleshooting] triplenine:
For What It's Worth...

Been lurking on a bunch of sites for the last week looking for solutions to this. I just picked up a replacement Captivate. The only modification I have made to the stock parameters are updating to JH7 and syncing to google to get my contacts. I can get it to shut off consistently. I have not plugged it in, rooted it, or hell, even used it. The only call made has been to the store to see if I can return this one as well.

So lame. I know I don't want to but do I just switch to the iPhone??? I don't think Samsung should be trying to sell Apple's phones :)
[Captivate Q&A, Help & Troubleshooting] gordec:
Last night, I turned off GPS and dismissed the "fully charged unplug your phone" notification. No shut downs today for me. I'm not sure which part did the trick but I'm gonna test it tonight by just keeping GPS off. I was one of those that had no problem with rooted stock for 2 weeks now with OTA it consistently, reproducibly (not a word) gets randoms shut downs after a full charge. I really don't feel it's a hardware issue.
[Captivate Q&A, Help & Troubleshooting] mrgoodwords:
Captivate shuts down a few times a day. I have tried stock rom, multiple versions of Cognition, removing Task Killer etc. with no improvement. I have even experienced the phone shutting down while on a call. So strange that it doesn't power down with a notification or anything. It just shuts off completely. Feels like a hardware issue to me.
[Captivate Q&A, Help & Troubleshooting] gordec:
That's pretty extreme. Doesn't sound like we are experiencing the same issues.
[Captivate Q&A, Help & Troubleshooting] kiltedthrower:
Thinking before I return. Are we saying that if we're having this shut down on occassion that the 2.2 update won't fix and that it's a hardware issue?
[Captivate Q&A, Help & Troubleshooting] SpartanGA:
My Captivate turned itself off and on about 10 times yesterday...literally one after the other. It finally stopped after I pulled the battery. Hoping it isnt a trend.
[Captivate Q&A, Help & Troubleshooting] RexEscape:
Here's the solution to everyone's shut down problems in just two sentences. Disable the GPS when not in use and see if your phone stays on in the next few days. If the GPS has been off all along and it still shuts down, have put it in for a repair or exchange it.

My 1st and 2nd Cap shut down on me like crazy. I'm on my 3rd and the only thing different is that my GPS is turned on only when I use Navigation. I always remember to turn it off. I have never gotten a shut down in 1 full month now.
[Captivate Q&A, Help & Troubleshooting] vinunleaded182:
random shutdowns might be caused by a faulty battery. Check out my thread here.

http://xdaforums.com/showthread.php?t=785742

If the battery is indeed the root cause (such as in my case) then Id suggest avoiding the OC/UV kernel. AT&T sent me a new battery for free and its working perfect now

Second note: the battery issue is tough to troubleshoot on the Captivate. The phone is designed to not boot without the battery even when plugged in. So if you have a faulty battery, the phone will treat it as if theres no battery in there.
[Captivate Q&A, Help & Troubleshooting] Belaflek:
looks like ill be hitting up batteries plus tomorrow abnd see what happens

damnit...they said no aftermarket batteries for like 6months to a year
[Captivate Q&A, Help & Troubleshooting] vinunleaded182:
LOL i was about to tell you that.
[Captivate Q&A, Help & Troubleshooting] 88EVGAFTW:
No shut downs yet. I have had the phone over a week. Turned it off 2-3 times on my own to reboot it or change battery (i use 2 when we go on long trips)

Phone stays on over night just fine and is not rooted yet.
[Captivate Q&A, Help & Troubleshooting] benjer712:
This has not solved the problem on the last two captivates I've had.
[Captivate Q&A, Help & Troubleshooting] swarlos86:
Just call att warranty center. they will send you a new battery free of charge. just talked to them today about the issue. They are shipping me a new battery to see if that fixes the problem. once the battery arrives they will call me to see how it is working. They said if it is still shutting down they will replace my phone. Att rocks.

Samsung customer service on the other hand does not. Don't even bother calling them, they do not have a replacement program, only a repair program. So if you cant be phone-less for at least a week or more, they are simply not an option. Nor do they guarantee that the phone will be fixed after you send it in to them. Which i have my doubts that it actually will be.

The tech at samsung did tell me something interesting though. Apparently the JH7 update did not address any gps issues. She said there will be another update soon. She didnt tell me what the update was for, but im guessing its a gps fix.
[Captivate Q&A, Help & Troubleshooting] swarlos86:
sorry for the double post could not figure out how to delete this one.
[Captivate Q&A, Help & Troubleshooting] phr00t:
I am going on my 3rd replacement phone which will likely come in early next week.

My first phone had trouble with the touch-sensitive buttons (specifically the search button).

My second phone has the "shutdown" problem. Now, this second phone is using the same battery as my first phone, which never shut down randomly. The AT&T warranty lady on the phone tried to push me to replace just the battery, but I made her give me a new phone. If it was the battery, why did it work perfectly fine until I put it into this refurbished phone?

Anyway, I highly suspect the battery isn't the problem... you will likely need another phone.
[Captivate Q&A, Help & Troubleshooting] FireRaider:
I gave up today and called ATT for a replacement phone.

I have 3 batteries and 2 chargers and it shuts down randomly with all of them. And the randomness is just that, random. Battery level varies, time of day, usage level, whatever. I can go a couple days or more with no shutdowns and then get 2 within an hour .

ATT questioned me about the charger and the battery so apparently there might be some known connection.

I am running Cognition 2.1.5 currently but it all started the first day I had the phone. I thought I had somehow bumped it, but soon discovered it would do it just sitting on my desk.

The odd part is just how absolutely random it all is.
[Captivate Q&A, Help & Troubleshooting] swarlos86:
This is my third captivate as well. Have had shut down issues with all 3. I figure its not the battery also. but i decided id play along with att's suggestion to try a different battery first. If by chance it does fix my problem, i wont have to redo all the settings and customizations on my phone. If it doesnt they will send me a new phone anyways.
[Captivate Q&A, Help & Troubleshooting] phr00t:
I should have just kept my first phone and delt with the search button randomly pressing itself... better than the phone turning off!

From what I hear, my next replacement phone will have shutdown problems too (or worse).

Although, the guy at the AT&T store said they will send you a new phone after your 4th warranty replacement. You are almost there! :rolleyes:
[Captivate Q&A, Help & Troubleshooting] swarlos86:
Yea a shut off issue is just unacceptable. I can deal with other things but not this. ATT offered me a new phone already if this battery thing doesnt work out. So I guess theyre not making me wait till after captivate #4. :D
[Captivate Q&A, Help & Troubleshooting] Belaflek:
Sucks, because I really like the phone
[Captivate Q&A, Help & Troubleshooting] skullvet:
This is my second phone. First one did the shutdown thing, now this one does it also. Did a factory restore, still doing it. No task manager, no root....plain old stock.

This is ridiculous.

I tried e-mailing Dale Sohn (President of Samsung mobile usa) and told him this was unacceptable. I tried a bunch of different e-mail conventions and all got returned to me except for one. Maybe I got through.

Will keep you updated. A copy of the e-mail I sent is below:

Is the network

Ok i think is the network or something like that, i am in my 3rd captivate an all of them shut off it self. I start to use my old iphone 3gs and live the captivate in home an use like an MID when it dont have the sim card it is all day on without any issue. Soon as i put again the sim it run well cuple of hours and then is off.

I use today but i download an app to turn off the data, after download and boot it again it dont have data and run all day without any issue.

All this make me think is something in the net work maybe im crazy but someone try it and let me know please!!!!

Sorry for my english!!!
[Captivate Q&A, Help & Troubleshooting] Algorismus:
After using 3 days, my phone started to shut down randomly,too. I had two shut downs, and i live in Turkey, no chance for a replacement :(
[Captivate Q&A, Help & Troubleshooting] bamonkey:
this is pretty weird stuff because this is my 2nd captivate and i started getting the random stutdown starting about a week ago. investigated this thread a bit and got to 'examining' my captivate and trying different things. Most attempts at software fixes failed..and i wasnt really suprised so i decided to try some mcguyver fixes and heres where it gets weird. Alot of stuff just did NOT work but finally i wondered what would happen if i tried to cross the 3 battery pins at the back with a staple and push the battery terminals against it. this felt absolutly crazy but hell im willing to think stupid sometimes. Well, for the first time it last a little over a day and a half but i left it in a hot car and well..damn the next day found it turned off around 38%...this got me thinking maybe the damn thing flexs when it gets hot..reminded me of the xbox360 problem we all know about these days. i decided to risk it and bend the pins a bit..NOT MUCH..just enough that maybe the contacts would be forced harder.. one actually broke :eek: so i just pressed it together and prayed to my captivate to work. well..so far im 3 days in, multiple charges performed and no reboot..

things could change and im not saying this is a fix...not in a long shot..just saying macgyver would be proud so far lol
[Captivate Q&A, Help & Troubleshooting] gordec:
Using Tasker script to turn off GPS whenever AC is plugged in. Now 48 hours without shut downs by turning of GPS everytime. So for those with shutdowns after charge, this is likely the solution.

I still want to know why GPS causes shut downs.
[Captivate Q&A, Help & Troubleshooting] triplenine:
I have to say...

I picked up my 3rd Captivate yesterday. So far I have to concur that it seems GPS related. I turned on the GPS (JF6) and was able to consistently get it to shut off from sleep. I have since shut off all location based services and (so far) it has not shut down. I don't know if this makes a difference but I disallowed google to use my location as well as turning off the GPS functionality in "Location and Security." On my second handset, I allowed google's location functionality and that is when I started seeing shutdowns.

I guess I am going to wait for a fix. Think we will see anything?

I'd like to continue to test in a close to stock format but I think I am going to root now so I can use it my way. I need to know if that has any effect because I am running out of time on my 30 days.
[Captivate Q&A, Help & Troubleshooting] Belaflek:
All my location stuff is off and it still dies. I don't need gps much if at all
[Captivate Q&A, Help & Troubleshooting] triplenine:
Huh, that concept keeps scraping away at the GPS theory throughout this thread. I am totally new to this platform but I have noticed that there are no system log discussions. Not to make this a different thing but is there a way to monitor a system and see what is happening? You would think that there would be some module that stands out as the culprit in these different "power down" instances.

I still am going lean toward a location based problem since I can make it happen but would love to see otherwise. I am trying to update my ATT rep with info as I have it.

EDIT: I should point out too that I am fully charged this morning so far and probably won't be surprised to see it as the day's usage goes on.
[Captivate Q&A, Help & Troubleshooting] vksf01:
just got my phone back from samsung. it looks like they also upgraded it to JH7 along the way. i'll see how it functions and hopefully it won't shut down.
[Captivate Q&A, Help & Troubleshooting] Algorismus:
could applications like battery time cause shut downs? After i installed battery time app, i encountered with shut downs. I removed that app.
[Captivate Q&A, Help & Troubleshooting] JamesAK:
Phone #1: Sent in for GPS & MMS related issues. Never had a shutdown issue, was purchased 2 days before release date. Was rooted & had various apps, and a halfway failed OTA

Phone #2: Stock. Updated to the JH7 via Mini Kies. Random shutdowns were noticed the following day.(granted I Kies'ed it pretty much right out of the box once I confirmed that the GPS was a no-go)

Yes I know that the update does not address the GPS, but some people have reported much improved results, I figured "well why not"

Phone was sent out for yet another refurb for the above stated issues

Phone #3: Stock, hesitant on doing the Kies just to see if it just "does this" or if it might be an update related thing.

Also on a side note, this is the same battery I've always had, figured that since it was fine on the first phone, shouldn't be the problem.

Ill keep everybody posted on the #3, fingers crossed.....

It is very possible that a battery app can speed up the aging process of a faulty battery. In m ycase I flashed the OC/UV kernel and my phone kept shutting down for a while and it wouldnt turn back on. AT&T sent me a new battery. BAM its back
[Captivate Q&A, Help & Troubleshooting] JamesAK:
Would it then be safe to say its not a battery related issue? Or maybe get 5 or so replacement batteries, that should rule out battery failure (or be a huuuuuge coincidence)
[Captivate Q&A, Help & Troubleshooting] vksf01:
That's similar to mine, although mine said

2.2 helping anyone?

I called and ordered a replacement phone last night. Tonight FROYO for the captivate was leaked and I have installed it.

I am hoping that along with the apparent fixes to the GPS problems, Samsung has also fixed whatever bug is causing the random shutdowns.

I pulled my SIM back out of my Tilt2 and will run it in my Captivate this weekend and see if I get any more of those annoying shutdowns.
[Captivate Q&A, Help & Troubleshooting] phr00t:
I'm still having the shutdown problem with JI6 Froyo. The shutdown problem is DEFINITELY a hardware problem, and the only fix is getting a working physical phone. Keep swapping it until you get one that doesn't shut down!
[Captivate Q&A, Help & Troubleshooting] a.n:
My phone was fine until I flashed JI6. Now I'm having the random shutdowns problem too. If I wasn't having this issue before I flashed JI6 and now I am, then it stands to reason I've done something during this process that is causing it.
[Captivate Q&A, Help & Troubleshooting] shutterbc:
Crap. I just had my 3rd incident in 3 weeks of the phone not waking up from sleep after it has been plugged in for multiple hours. Looks like I'm definitely in this camp now.

From the sound of things, many people attribute this to a hardware issue. Has anyone gotten closer to discovering the underlying cause of this problem? For me it seems to happen right after unplugging the device, for example (maybe a charge circuit issue, who knows)

I bought this phone second-hand from someone without the receipt (but with the original box). I'm wondering if that's going to make it very difficult for me to exchange. Any tips?
[Captivate Q&A, Help & Troubleshooting] phr00t:
My first phone never shutdown randomly -- not once. The moment I got a replacement phone (because my first one had funky touch-sensitive buttons), the shutdown problems started. Same battery that worked in my first phone too. No matter what ROM I flashed, or how many times I returned to stock settings -- it shutdown. Most of the time right after a full charge.

Maybe some phones are more sensitive to shutdowns than others? Anyway, I'm pretty sure the only way to have a phone not randomly shutdown, is to get a phone that doesn't randomly shutdown.
