[Captivate Q&A, Help & Troubleshooting] androidftwin:
I guess this is whats happening to mine also. After a full charge, I click OK then unplug. I'm not too sure how long after it shuts off but it always does when the battery is full. Doesnt seem to happen when the battery is less than 90 percent or even 95 when i turn the phone back on.
[Captivate Q&A, Help & Troubleshooting] jcylcruzin:
Guys, has anyone tapped "software update" in settings today? I installed an update, but it didn't change anything noticeably. Firmware still says 2.1-update1, Kernel still shows 2.6.29 jetaek.lee@sep-11#2 and build is still Eclair.

So what was updated? Does anyone know? Anyone thinks it might include a fix for the random shutdown issue?

I tried calling Samsung and the lower echelons so called "techs" have no idea either what was updated.
[Captivate Q&A, Help & Troubleshooting] dirtyhans:
So,

Interesting bit of info. regarding shutdown and was wondering if anyone else is seeing this.

So, I'm on my 3rd phone and it will randomly shutdown like everyone else in this thread is complaining about. My co-worker's phone never once had an issue.

Well, today he borrowed my charging cable and bam!! an hour later it randomly turned off...

The charging cable is not the one supplied by Samsung, and is just a charging cable...not a data cable.

any buddy else just using a charging cable (ie. not a true data cable) to charge their phone and getting the reboots?
[Captivate Q&A, Help & Troubleshooting] genem1:
Yes, this was my situation for two of my three shutdown events (since my 7/30 purchase). Each event had multiple shutdowns, but once passed I was ok.

The first time was out camping, happened the next morning so I was >12 hours from the last charge.

I am thinking this has something to do with the OS' sleep mode. (Not just screen off - the OS Sleep Mode)

I run Android System Info.

Click on System | OS.

Right now, it shows almost 4 days since boot (last time my phone powered off on its own), and under that it shows: Up time(without sleep) as 1 day, 20 hours.

I don't know what allows the phone to enter this sleep mode, but when mine doesn't sleep for a long time (like shown here), I don't have the problem.
[Captivate Q&A, Help & Troubleshooting] androidftwin:
Im coming home tonight from my trip and my new phone will be in the mail so I'll keep you guys updated. Hopefully it does not turn off on me or I will be super sad hahah
[Captivate Q&A, Help & Troubleshooting] jcylcruzin:
Well the next time you charge fully, would you give the workaround a try and let me know if that alleviates the problem for you?
[Captivate Q&A, Help & Troubleshooting] jcylcruzin:
My experience is that multiple shutdowns will occur if I don't do the following workaround. following a full 100% recharge and immediately after unplugging the usb cable 1) dismiss the fully charged popup 2) use your phone for a few minutes until it no longer detects 100% battery charge. (I've had luck at 98% charge) -your phone should not shut down after the rest of the day even if left to languish idly on your flat desk surface. Works for me -tell me if it works for you?
[Captivate Q&A, Help & Troubleshooting] evosky:
i turned off the gps setting and that seems to have worked for me for a day at least. also, the random shutting down didnt start occurring until ... about a month into my ownership
[Captivate Q&A, Help & Troubleshooting] 88EVGAFTW:
So far the new replacement phone has been working flawlessly, while the one I need to send back to rma is still shutting down like no tomorrow.
[Captivate Q&A, Help & Troubleshooting] nuwayman:
I had my first shut down last night after owning this for a week and a half. It was charging overnight on my night stand. Hopefully that was just a fluke and doesnt happen again. Ive never had it shut down randomly yet during the day. I guess we'll see what happens now.
[Captivate Q&A, Help & Troubleshooting] malcom1120:
Got my replacement phone last night. I have my fingers crossed.
[Captivate Q&A, Help & Troubleshooting] vksf01:
did you get it from samsung or att?
[Captivate Q&A, Help & Troubleshooting] 88EVGAFTW:
I haven't done that to my new phone, I just let it charge to 100% and un plugged it them hit ok on the message. Been fine so far
[Captivate Q&A, Help & Troubleshooting] genem1:
For the last two mornings, I've been trying to reproduce the problem by charging all night and just performing step 1. So far it has continued to work. Between my two tests, I've installed the AT&T Update, but I assume that will be unrelated.

(Purchased 7/30, Mfg'ing date 7/18. Three shut down events since. each event: multiple shutdowns every few minutes-once when in my pocket & walking around.)
[Captivate Q&A, Help & Troubleshooting] deejaylamb0:
Where I am, it's 6:49 on a Sunday. This phone is not healthy for us haha but check it

(Purchased 7/30, Mfg'ing date 7/18. Three shut down events since. each event: multiple shutdowns every few minutes-once when in my pocket & walking around.)[/QUOTE]

Similar issues, once while in pocket, twice will phone was sitting on an armrest...

What I DID notice after reading almost all of these 36 pages that hasn't often been mentioned is this key element:

"every few minutes"

...The reason I say this matters is because mine does it too... Around 75% battery, 3 times in 15 minutes...

Since you guys appreciate any NEW proposed fix:

------> Removing ADW.Launcher *failed* aka still had "offs"

------> Just removed Dolphin Browser HD, and now I don't get ANY shutdowns.....

Sooooo since I'm a relative rookie but I still know enough about hardware and the android software, I know this is NOT A PERMANENT FIX BECAUSE 99% of the people in this thread probably never had ADW and DbrowserHD combined...

*ALSO NOTED*

Previous posters have nix'd the batch issue... HOWEVER the older manufacture dates AND the "middle" dates aka July [most say 7/18] both fail...

Pray

you got/get an August phone!!!

Summary of my week of testing and 3+ hours of research:

I unfortunately have a couple bleak conclusions.

(I) Hardware production inconsistency {faulted parts not short-circuiting since the whole phone would die, but rather limits flow like a bottleneck, which causes your average electronic device to shut down... much like your phone staying on for an extra second then fading off when you pull the battery}

-or-

(II) Not an Android fault but the adaptation BY Samsung for the Captivate {if this IS correct, if someone were able to completely wipe the Samsung-ness aspects, the phone would work fine... But that's impossible.}

*sigh* I hope this helps some people. I am going to do an inside-30-day replacement... If that one also randomly dies, I will roll deep with a gansta ghetto X10 *gasp, traitor!* ... Better battery life, and oh yeah, their major malfunction is a lock screen, not a shut off... But the SAMOLED is like crack, can I now live without it?????
[Captivate Q&A, Help & Troubleshooting] jcylcruzin:
Actually, I think there may have been something in the At&t "GPS Fix" update... I installed the update and decided to stop the workaround as a test. It's been 2days with 2 full charging cycles the phone failed to disappoint! I even used the phone a bit then re-charged to 100% and re-created my bad habit -yet no coma! Even without dismissal of the fully charged popup!

My phone reliably goes into a coma upon unplugging usb charge cable within 30mins if workaround is not applied. So -does this mean Samsung snuck in a fix?

Has anyone else experienced this miraculous recovery?
[Captivate Q&A, Help & Troubleshooting] silenzzzz:
i am on my second one ... first one would shut off all the time on me no matter what .. this one only shuts off once after a full charge then it is good to go again after that till i do another full charge (which i try to avoid doing sadly) ... i may swap this one out one last time before the 30 days is up ...

and mine has the OTA fix on it ... was doing it before and after the fix
[Captivate Q&A, Help & Troubleshooting] darthmalus:
its kind of funny mine didnt start turning it self off until 30 days after i got it, and i now cannot exchange it for a different phone. Mine is not rooted, dont have Setcpu on it, nothing along the lines of altering the phone in anyway, and it turns it self off, some say its because of "ATK" removed it and still the same. Maybe its a ploy from at&t to get people to spend more money who knows.
[Captivate Q&A, Help & Troubleshooting] silenzzzz:
has anyone that is having the shut down issue tried a custom rom on it? just wondering if it still has the issue...
[Captivate Q&A, Help & Troubleshooting] Warjcowski:
Unhelpful's kernel / DG's rom fixed it for me.

[Captivate Q&A, Help & Troubleshooting] belayson:
Used to have a pretty bad shutdown problem on my no root, purely stock phone with alot of basic apps and games. What works for me is to keep the wifi and gps on at all times, as soon as i turn off wifi, give it an hour and it'll turn off, gps, same thing. I guess its a bit of an energy drainer to have both on but what can you do? atleast i can use my phone as an alarm again lol
[Captivate Q&A, Help & Troubleshooting] swarlos86:
My phone never shut down till after 30 days in. When it first started to shut down, it did it randomly but rarely. Now after the JH7 update it seems to consistently only shut off after a full nights charge. If i allow it to idle after a charge it shuts itself off. But once im past 95% charge left it will no longer shut off. Gonna talk to AT&T about it tomorrow. This is captivate #3.
[Captivate Q&A, Help & Troubleshooting] Foxman13:
I am seeing this exact same behavior ^^^^^. After a full charge, it shuts down after going idle the first time. After the new update, it does it consistently and I also get the "Congratulations!" message about the software update after having dismissed it several times.

Historically, the shutdowns were seemingly random, but now it is apparent when it is doing it exactly.
[Captivate Q&A, Help & Troubleshooting] thebestguru333:
Had my 2nd for about 5 days. So far zero shutdowns. I purposely drained the battery and did a full charge and observed it during multiple idle processes during the first 15% of the battery life and no shutdowns. I will be a happy camper if the shut downs never happen. I will feel ripped of they happen after my 30 days. In that case I will haggle at&t till they fully refund me.

Wish me luck. I will update upon first shutdown. If not I will consistently check the thread anyways.
[Captivate Q&A, Help & Troubleshooting] heygrl:
Im wondering why this only seems to effect the Captivate and Bell Vibrant? 850 3G???

i dont know about urs but my Vibrant rocks
[Captivate Q&A, Help & Troubleshooting] broadrivr:
You may be right. My phone will turn off on its own sometimes when i plug it into the usb port on my car stereo and mount it. My stereo will continue to let me play music from the phone even though i cant wake the screen up until i soft reset it. A fews times its done this when I mount it to my pc. Sometimes the screen will just go black and the soft keys will remain lit but the screen wont wake up. A soft reset fixes it though. Its a minor annoyance i have with the phone, but im not willing to give it up for that though :)
[Captivate Q&A, Help & Troubleshooting] fergsm:
A think is network problem

I have sema issue mi samsung captivate ramdomly turn off i chenge 3times and the of att toldme i dont have more echange ,

This last one work fine the first 3 days then it strart to power of its self, i pull out the sim card and i use an iphone again, i live the captivate only with wifi but now it dont get the shot down issue. I think is a sim problem or network problem this is the day 4 and it is on

Sorry for my english jajajajaj

I hope this info help to solve the problem
[Captivate Q&A, Help & Troubleshooting] 88EVGAFTW:
I've plugged and unplugged mine all kinds of different ways, been fine so far, and it has the new update on it as well but stock apps un rooted. Also the battery life seems to have gotten a bit getter, especially in flight mode.
[Captivate Q&A, Help & Troubleshooting] evosky:
i think it really is random. i leave my phone in my car when i'm at work since i can't bring it in, and sometimes when i go back, it's shutdown. also, sometimes when i wake up in the morning, the phone is also shutdown even though it had almost a full battery and was not plugged into anything. i've also tried leaving gps on and turning it off to see if that was affecting anything, and it seems like it doesn't do much at all. i've also had my phone in my pocket and was definitley on before going in there, and when i go to pull it out, it's been turned off. i'm thinking it's definitely some software bug that detects a certain state of variables and triggers a shutdown.
[Captivate Q&A, Help & Troubleshooting] Jack45:
Every so often I'm compelled to reply to posts indicating that software is to blame for random shutdowns. Let me be clear...random shutdowns have nothing to do with Market apps unless you tweak settings (e.g., SetCPU) to crazy levels. Other than that instance, there is one and only one remedy to what has been a bad batch of devices: exchange the phone. I can't be any clearer.
[Captivate Q&A, Help & Troubleshooting] rizzo1001:
RMA'd mine to Samsung yesterday. Here's to hoping...
[Captivate Q&A, Help & Troubleshooting] Belaflek:
I bricked my first, RMA, Random shutdowns on the last, RMA, had this one a week..just started to shutdown. One of the things I noticed in the recent update, according to the notes, was that it did not address an issue of it shutting down when its memory got full or something liek that so I tossed in Advanced Task killer to see if that helps..one more week and RMA #3.
[Captivate Q&A, Help & Troubleshooting] Jack45:
You're wasting a week. Exchange it.
[Captivate Q&A, Help & Troubleshooting] Belaflek:
lol..the other reason im giving it a week is I want my phone on the weekend..so. Ill RMA send it in Monday get it on friday.
[Captivate Q&A, Help & Troubleshooting] evosky:
yeah i agree with you on your point. i'm not talking about market apps though, i'm talking about a system software bug, which makes sense if there was a bad batch of devices (very likely for me since i think i got mine about 1-2 weeks after the release date). again, software != only applications. software encompasses a ton of things, including low level firmware and processor instructions.

but yes, if it goes on for a week or so longer, i'm going to request an exchange/replacement if possible.
[Captivate Q&A, Help & Troubleshooting] Belaflek:
the only time it shuts down is when its goes to sleep mind you...not that it matter just something to chew on

I've been on jh7 for a few days.. I didn't have any of the shutdowns before but now I get them after a full charge over night after I unplug it and let it go isle the first time..booooooo
[Captivate Q&A, Help & Troubleshooting] gordec:
Anyone knows how to fix the random shutdowns after unplugging from wall charger in the morning. This started after JH7 update. I used the Odin flash. It's not a big deal to turn my phone on once a day but kind of annoy. I tried to dismiss the battery is full notification and keep it plug but it's not doing anything. I don't want to flash back to stock again even though my GPS is not working so great after this JH7 anyways.
[Captivate Q&A, Help & Troubleshooting] wfrandy:
Wow, we were all ready to have to do some talking to get my wife's Captivate replaced, turned out to be no problem at all. She walked into the AT&T store, and her account rep saw her and said, "let me guess, your here to get your phone replaced because it randomly shuts down on it's own". My wife said she was a good guesser. Her rep said that they had been getting a few of them the last few weeks. Her rep swapped her sim card and my wife left with a new phone 10 minutes after walking in the store.
[Captivate Q&A, Help & Troubleshooting] gordec:
Is she within 30 days?
[Captivate Q&A, Help & Troubleshooting] wfrandy:
Take it in and get it replaced, this is not a software problem, and if it works like my wife's phone did, it will continue to get worse with time. With her phone it worked fine for about a week. Then for another week or so it would just shut down once a day when she unplugged it. Once in a while it would go a whole day without shutting down, but by the last day she had it it was shutting down sometimes as many as a dozen times a day. She took it back 3 days before her 30 days was up.
[Captivate Q&A, Help & Troubleshooting] :
If I recall, there was an issue with N1's acting up if clocked too slow also. SetCPU is showing 100Mhz when it bottoms out and my N1 baselined at 275....so maybe that is it cus I've had the same problems with it not waking and needing to pull the battery. I did a restore of my Nandroid backup from yesterday and the problem stopped....the only different apps I had installed were MarketEnabler,PDANet, and Appbrain. I did a complete wipe before the restore...

Captivate Shutting Down

Gah! Mine's doing the same thing! I bought this phone last Friday and it worked great for the first day and a half. Then after the second full charge it started shutting down for no reason. Thought it might have been the battery, which once I took the door off, did seem slightly loose on the end without the connectors. I taped a piece of paperboard in between the case and the battery so it didn't wiggle at all. And it STILL does it!

I'm thinking I might take it back and exchange it at the store at lunch today.

I have a few downloaded apps, basic ones only, nothing rooted and no changed major user preferences.

*sigh* this phone would be perfect if it would just STAY ON!!!! :mad:
[Captivate Q&A, Help & Troubleshooting] jakkzen:
I think it's "setcpu" causing it. I removed the app and it hasn't shut off since.
[Captivate Q&A, Help & Troubleshooting] THATTON:
I can confirm that on MY Captivate it WAS DEFINITELY SetCPU. I didn't have to remove it though. I just made sure that the minimum frequency set was 200mHz and not 100mHz which is the default. Mine still hasn't shut off since then.
[Captivate Q&A, Help & Troubleshooting] :
Might also want to turn off auto kill on your task killers...my phone was dropping every call as soon as I put it up to my face. I uninstalled Task Panel and problem solved. I don't know how or if it could be related but I reinstalled it and made sure it didn't auto kill and my phone is still working great. And yes I was at home with full bars the whole time and I threw my sim card in an old Blackberry to make sure it wasn't just AT&T bugging out. It seems like these phones respond REALLY well to task killers lol. Be careful.
[Captivate Q&A, Help & Troubleshooting] THATTON:
Furthermore, SetCPU doesn't actually make the phone shut off, it is only the OnDemand governor that does. If I leave it on conservative then it doesn't shut off even with SetCPU installed.
[Captivate Q&A, Help & Troubleshooting] ieee1394:
This happened to me today. Brand new Captivate, picked up over the weekend (3 days old). The only apps I've installed so far: Barcode Scanner, Open Table, Key Ring, Adobe Reader, Digg, Documents To Go. Not rooted. No SetCpu, etc. Configured Exchange.

Before it froze (went to permanent sleep) I installed a Google Maps update, and fully charged until a message appeared prompting me to disconnect the charger.

[Captivate Q&A, Help & Troubleshooting] brisknfade:
This is quite annoying. I've flashed the JM2 rom from the i9000 thinking it might be something screwy with the att rom, but to no avail. Still turns off from time to time.

Happened again just now no less then 2 minutes from coming off the charger.
[Captivate Q&A, Help & Troubleshooting] ieee1394:
I think what would be best is if those that have posted about this problem could track or note whether or not this problem occurred after charging the phone or using the phone's USB port in any way. It also might be helpful to know if the phone's included charger was used or if another USB charger was used instead.
[Captivate Q&A, Help & Troubleshooting] xtsuname:
I have had the same problem. For some reason it stops doing that after I changed my wallpaper. All I have installed on my phone are apps from google.

I am not sure why changing the wallpaper will stop it from randomly shutting down.

Could someone give this a try to see if it works?
[Captivate Q&A, Help & Troubleshooting] ieee1394:
That's bizarre. Which wallpaper? I'm using swaying grass.
[Captivate Q&A, Help & Troubleshooting] xtsuname:
At first I was using Aurora then switched to Blue Sea. That fixed it for a day. Then I plugged it to my computer via the given USB cable.

Then the next day it started doing the same thing again. Switched to a still background and that fixed it.

I do realize that at both times the battery has drained and it's not at 100% anymore. If that might be the problem.

My friend doesn't have this problem and we switched batteries and it still happens, before the wallpaper switch.

Reproduced exactly the same

I was able to reproduce mine exactly the same way. Last night I put my phone on the charger before bed and left it on all night. I took it off this morning and set it to vibrate when I left for work. My 9:30 AM meeting notification went off as usual and as I was about to pick up my phone to dismiss it I rememberd that I didn't do that last time this happened so I just left my phone alone. I went to my meeting for 30 mins and when I got back the phone was off. Those were the EXACT same steps that happened last time.

Recap:

- Full night's charge

- Turned to silent

- Left phone alone when meeting reminder came up

- 30 mins later tried to take phone out of standby and wouldn't come up

Sidenotes:

- Swaying grass live wallpaper

- No downloads other than gmaps and some games

*** I emailed Samsung about this problem and everybody with this issue should do the same or it won't get addressed!!!
[Captivate Q&A, Help & Troubleshooting] dirtblade:
I've sent the problem description to Samsung too. Damn! I really like this phone but this problem I can't deal with if it is not fixed....
[Captivate Q&A, Help & Troubleshooting] jsouza1:
I've been experiencing this too.

However, I think I've partially figured this out. The random shutdowns appear to occur if the phone is allowed to sit idle for a period of time, like on a desk or table. If I keep the phone in my pants pocket, where it is slightly moved frequently, even if I am sitting at my desk, the phone does not randomly shut down. My guess is that the frequent slight movement keeps the gyros active which in turn keep the phone CPU active and thus the phone does not shut down. Samsung likely needs to change the default power profile for the device in order to fix this.

I've cross-posted this on the AT&T site (forums) and also emailed Samsung via the Galaxy site. Hopefully they'll have a fix soon.
[Captivate Q&A, Help & Troubleshooting] spyz88:
Did everyone try to make sure the battery door is closed TIGHTLY? Also, when you take the battery out look at the metal contacts. Are they all even or is one bent/jacked up? It seems if you place the battery in backwards that messes up the contacts and that could be another reason. As far as changing the wallpaper I think its just a coincidence.

P.S. If you hit up Sammy on Twitter they will help you out. They sent me a new battery door.

Okay, so this series of unfortunate events seems to be the key for me. Every Monday, Wednesday and Friday morning for the past 2 weeks I have gone through this routine above and at the same time everyday when I get back from my status meeting at work my phone is dead.

It HAS to have something to do with charging the phone or connecting the USB.
