[Captivate Q&A, Help & Troubleshooting] obelix74:
ok guys, I may be headed somewhere. At this point, it is just speculation.

Last week, I started fresh. I started with the factory installed 2.1 and made no changes, worked fine for a few days.

Flashed to Odin 2.2, worked fine for a few days. I only installed google blessed software in that period.

Last night, I installed

Angry Birds

Jewels

Sudoku Free

Paper Toss

Solitaire

Basically the top 5 games in the free section. Played Angry Birds heavily and no other game.

Let the phone to sleep over night and it is dead in the morning. The application short cut I had for Angry Birds was missing when I restarted the phone. (Red Herring?)

When I look back, my shutdowns started fairly recently. The only thing that changed fairly recently was Angry Birds. I don't ever remember having this problem pre Angry Birds days.

For those who has had the shutting down problem, do you have Angry Birds?

I have uninstalled all the games (yeah, I know, should have just uninstalled Angry Birds).

I will see if my phone doesn't die today. If it doesn't die today, I will reinstall one game a day (other than Angry Birds) and see what happens.
[Captivate Q&A, Help & Troubleshooting] Houndog:
By the way, there is a new Angry Birds update and now it can be found in market for Captivate. If this turns out to be a problem, maybe this update could help.
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
Hi Hound, hate to tell you, but thats not the issue.

Many people (myself included) have had the shutdown problem with stock captivates, using factory reset to get the phone back to its original setup, without installing anything else, the phone still has this problem.

Surprisingly, my phone has gone back to normal (for the past two days of regular use)... this was after a factory reset that did no good. I did however have CaptivateKeepAlive running for a while, but then disabled and uninstalled it in an interest to try other solutions or to have the error present when i brought it in for exchange. However, i haven't had any problems with the phone since then.

I thought maybe running CAK triggered some switch or setting, that was misbehaving before.
[Captivate Q&A, Help & Troubleshooting] obelix74:
Hound

When was this update released? I installed AngryBirds last night.

BTW, ~3 hours after I uninstalled AngryBirds, my phone hasn't died yet, in the past, it would die pretty promptly. I will update my progress here.

FWIW, as I say in my previous post, I did a clean flash reinstall of the stock 2.1 ROM using Odin and started over. After a week, moved to 2.2 ROM using Odin. No shut downs until last night, which I suspect is due to Angry Birds (or could be any graphics / CPU intensive app). If I can keep the phone from shutting down at this current state (no Angry birds), at least that is what works for me.
[Captivate Q&A, Help & Troubleshooting] diablo009:
Tough luck:

Here are the ROMs I tried:

1. Stock 2.2 (leaked AT&T Froyo version), unmodded

2. JPA 2.2 with I9000, just bloatware deleted

3. One more version of I9000, unmodded

4. Stock 2.1 JF7, unmodded

Turning off by itself has become more like a standard for this phone now!

This is my third phone. I got this one under warranty exchange only late y'day evening, and today, I was using it well till like 12.15PM, hardly giving it time to sleep.

Its 1.05 PM now, and its died out twice. Worst part was when I was on call with someone, and the other person thought I cut the call :-(

I am now in a totally frustrated state. Going home, will re-install stock JF6, and see how it works. Right now I have 2.2, unmodded.

Note: All are clean and fresh installs with phone and internal memory card formatted.
[Captivate Q&A, Help & Troubleshooting] diablo009:
Am facing this, even with setCPU uninstalled. Even a fresh ROM install after clean format to remove all traces of setCPU not helping!!!
[Captivate Q&A, Help & Troubleshooting] diablo009:
I exchanged only last night. And this piece already restarted twice today, once when I was on call, and the phone wasn't even asleep..!!
[Captivate Q&A, Help & Troubleshooting] chasesavestheday:
has anyone had a shutdown while using captivate keepalive?
[Captivate Q&A, Help & Troubleshooting] AlienHairball:
Yep. My wife's Captivate that I just shipped back this morning was having massive shutdown problems whether running Captivate Keep Alive or not. We're talking about a shutdown nearly ever single time the phone was left sitting for more than a couple minutes so you could easily see 5+ shutdowns an hour.

I'm certainly hoping the replacement will be from a healthier batch.
[Captivate Q&A, Help & Troubleshooting] chasesavestheday:
i havent heard of anyone with symptoms like your wifes! i get one every couple of days. rarely do i get 2 in one day.

when using CKA does it auto run when phone is reboot? or do i always have to open it and hit refresh keep alive?
[Captivate Q&A, Help & Troubleshooting] AlienHairball:
Yeah it's weird. She had several shutdowns when we first got our Captivates, then hardly any for a week, but over the last couple of days it's been constant shutdowns so the phone gets exchanged.

This problem is definitely a pain for what is otherwise an amazing device.
[Captivate Q&A, Help & Troubleshooting] chasesavestheday:

[Captivate Q&A, Help & Troubleshooting] claudeswares:
If you reboot, you must start it manually.

Also, I when I called AT&T, the Android representative, told me AT&T acknowledges the random shutdowns as a known device issue. They sent me a battery replacement first just to be sure, but it didn't work. They are sending me a replacement. As many other people have stated before, if you are having this problem the only real solution is to exchange your phone.
[Captivate Q&A, Help & Troubleshooting] NunHugger:
Mine was shutting down two or three times a day. Got it replaced and it has yet to shut down once. Take it back..and I am sure if you are beyond the 30day, you could send it in to get it replaced.
[Captivate Q&A, Help & Troubleshooting] genem1:
This week I had my first power-off since the minor update AT&T published weeks back that included the QuickOffice stuff.

When the power-off happened, it was also the first time my phone was in a low-signal environment (the blue-not-sign rather than the 5 signal strength bars) since that update. I put the phone in my pocket for about 2 min. Took it out, pressed the button once, and it began to power up. Upon power up, the battery was reading 51% (not full). This is the same as my other power-off events (camping, battery below half, no cell signal but Not in flight mode).
[Captivate Q&A, Help & Troubleshooting] pkley:
Had my phone replaced for the lack of hardware Recovery/Download mode, replacement immediately started shutting down after the first night. Also shut down during calls twice.

Didn't help me at all

My initial replacement was refurb running JH7 and had the issue. Second replacement was obviously new, running JI6. No problems. They even called me to make sure it was working right!

AT&T didn't blink at replacing my phone, twice in one week.

I was beyond 30 days on both replacements.
[Captivate Q&A, Help & Troubleshooting] Jack45:
To reiterate, CKA deals with only

one

of the reasons the Captivate suffers from random shutdowns. The others affecting power management are unrelated to high-charge level circumstances which is what CKA was designed for.
[Captivate Q&A, Help & Troubleshooting] tguru8989:
I'm currently using Keep Alive and everything is working okay. No shut downs yet. Any word on what Samsung is planning to do about this? I don't want to have to exchange my phone every three weeks. I made that mistake when I purchased the Motorolla Crapflip.
[Captivate Q&A, Help & Troubleshooting] Jack45:
Yes. They're planning to update their script from:

"This is the first time I've heard of this. Try a factory reset."

to

"This is the second time I've heard of this. Try a factory reset."

Useless, but progress nonetheless.
[Captivate Q&A, Help & Troubleshooting] Houndog:
I am convinced that after much reading and some practical experience myself, unfortunately, both the random shutdown issue and some of the GPS issue has to do with things not getting cleared up correctly on the phone as both seem to work better when everything is wiped and you start over from scratch. I think the GPS issue maybe related to GPS cache not getting cleared or reset appropriately or whatever should happen, and the random shutdowns seemed to happen more for me after I started having the phone shutdown on me. I think that this phone and maybe android may have issues that they have not resolved with proper handling of cached files when something abnormal happens like a shutdown or loss of signal. Just my thoughts.
[Captivate Q&A, Help & Troubleshooting] tguru8989:
Does anyone in the warranty department speak English?? Try a factory reset sir..... I did five times... Can you try again sir?

Are they serious??
[Captivate Q&A, Help & Troubleshooting] obelix74:
ok people, it was not any software issue.

I took it into AT&T's warranty division in San Jose, CA. The technician replaced it with a new phone - no questions asked.

He says they are aware of the problem. Samsung is aware of the problem and has fixed it in the new batch of phones. The phone I have is supposedly a new batch phone. Let us see how this goes.
[Captivate Q&A, Help & Troubleshooting] chasesavestheday:
i just called the warranty dept, and they are first sending a new battery. lame. and i know it wont fix anything. they were real cool about the situation. though they did ask me what color the battery prongs were on the phone, gold or silver. i suppose thats because all at&t versions are gold. rogers might be silver?

let us know how the new one goes. im certainly calling the day i get the new battery and asking for a new device.
[Captivate Q&A, Help & Troubleshooting] tguru8989:
My device is a little less than one day old, they're sending a whole new device over night shipping!
[Captivate Q&A, Help & Troubleshooting] BL4zD:
Just because AT&T is replacing our Captivates does not mean that it's a hardware issue. It just means it's faster and simpler to recycle the phones than try and get the one in your hand working.

They don't want tech support on the phone for hours trying to get a handset working when they can just swap a battery or device and clear the case.
[Captivate Q&A, Help & Troubleshooting] obelix74:
Oh. I went through the battery route too. There's a benefit to this. At least to me they letme keep your old battery:)
[Captivate Q&A, Help & Troubleshooting] obelix74:
Well in my case the technician accepted that this is a problem with the captivate and samsung is aware of it and fixed it.

Fingers crossed.
[Captivate Q&A, Help & Troubleshooting] tguru8989:
Evrything seems good so far. I have all the same apps installed. Only thing I haven't done yet is USB to PC. To be honest my problems didn't start until I tried to do that last time. No real need for it right now any ways.
[Captivate Q&A, Help & Troubleshooting] uhmump95:
I have noticed that when my Captivate shuts down, I have left the USB port open.

I also had it shut down after Lookout found some spyware on my phone.
[Captivate Q&A, Help & Troubleshooting] pdiggitydogg:
Can you post the ID number of the "new" phone, compared with that of ones that are known to shut down? If theyre different, and its fixed, Ill accept its a model issue.

I want a captivate SO bad but I dont want to deal with the stupid shut down issue...
[Captivate Q&A, Help & Troubleshooting] Maroon Mushroom:
I had this same issue. The second I disabled the superuser permissions of SetCPU it fixed itself.

Hope this helps if you have that app installed.
[Captivate Q&A, Help & Troubleshooting] DesertZero:
My mileage is, in fact, different...my phone just shut itself down again and I checked what you suggested. I must have already turned it off when I got the phone as this option was already unchecked.

This is getting quite annoying.
[Captivate Q&A, Help & Troubleshooting] ice3186:
Possible answer

Okay so here is the skinny on how my Captivate is set up.

I am running not only ATK, but AutoMemManager AND Setcpu.

According to this thread I am doing everything wrong.

I have read the whole string and taken into account a few things. And i am running stable now.

1.) If you are using setcpu make sure your not running any profile or setting that is "on demand"

2.) Never set any of your profiles to anything less than 400MHz

3.) If your having problems with your alarm clock or what not shutting down, go into either AutoMemory or ATK and set that program to "ignore" or "white list"

4.) some programs to consider whitlisting: Live wallpapers if your using them, Android System, Clock, your email programs for push, Swype, your MemManager, things like that

5.) I have my kill intervals on both programs set to as often as possible and in ATK i am on the safe setting.

Okay I think that is the skinny.

Things to note:

I am running the method 1 speed fix (just search the forum)

I am getting quadrant scores up to 950, always above 900( i was getting about 850-860 previously)

hope this helps and just post back if your having problems!
[Captivate Q&A, Help & Troubleshooting] zorphnog:
Just saw this thread as I had previously posted the same topic in the General Captivate subforum. I have the same issue and I went as far as reinstalling the stock ROM and have no Apps installed at all, and the issue still exists.

The only thing I have done since reflashing the stock ROM is sync my google account and my work exchange account. I saw a previous post in here about calendar events causing the issue. Maybe an exchange account issue with the email client?
[Captivate Q&A, Help & Troubleshooting] eatkabab:
I have a whole new dimension of whats going on. My phone NEVER did this until I did a factory reset. Now I get good-ish batt, but it seems to restart at roughly the same time each night.

I don't have any CPU clocker or task killer but I do have launcher pro and I did before my reset as well.

This is terrible, I cant rely on my phone as an alarm anymore. this MUST be fixed. It turned off twice in 2 hrs last night.
[Captivate Q&A, Help & Troubleshooting] checkers2884:
Call Samsung Galaxy S Support

I called Galaxy S Support which is a special tier that you will be forwarded to when you tell the customer service tech that you have a Galaxy S phone. The guy I talked to said that he was unaware of any issue like the one we are experiencing. PLEASE make sure you are calling Galaxy S tech support because if they do not get enough calls about this, they will just dismiss it as a defective device which I really don't think it is.

There have been issues in the past with other Android phones having the same problem. This is something they should really be handling on their end I believe and not something that we should be returning phones for.

As far as my phone's setup is concerned, I have NO apps at all for memory or CPU management. My previous post can describe the exact series of events that causes the issue every time for me. I don't mean to sound like a jerk here but seriously try to take the time to bug Samsung about this issue because this is their flagship phone line and they will definitely fix the issue if they know it's spread out wide enough. Make sure you call them. If you just email them the email response you get will be worthless.
[Captivate Q&A, Help & Troubleshooting] Ricparr:
Same issue here. I don't use setcpu and it is not rooted yet, nor do I use an alternative launcher/home. I do have ATK and that's about it. I hope someone comes up with a solution for this, I would hate to see my phone go back or even the entire galaxy s line for that matter, over a bug!
[Captivate Q&A, Help & Troubleshooting] checkers2884:
Hey guys, I was having this problem as well. I called the Samsung Galaxy S premier support line and the tech suggested a factory reset by typing in the following on the dial pad:

*2767 *3855 #

Since doing this a week ago I haven't had my phone shutdown on it's own. FYI, it WILL RESET EVERYTHING so please remove your sim and SD card before doing so and backup anything you have stored on the internal flash memory. ALSO, I highly suggest doing this with a fully charged battery just in case.

Let me know if this helps anyone else.
[Captivate Q&A, Help & Troubleshooting] eatkabab:
Whats the number? I'll call every single damn day. I'm so annoyed that every time I go to use my phone its frikin OFF!
[Captivate Q&A, Help & Troubleshooting] checkers2884:
Unfortunately, there is no direct number. You will just have to call Samsung tech support and tell them that you have a Galaxy S phone and would like to speak with the Galaxy S Premier tech support. As soon as I told the girl my model number she just transferred me and said she wasn't properly trained to troubleshoot that line of phone.

Like I mentioned in my previous post, try the factory reset.
[Captivate Q&A, Help & Troubleshooting] yinNout:
It may actually just be a defective device. I experienced the same issue and wound up exchanging the phone for a new one. While the old one would shut down while charging each night, the new one has not, despite having all the same apps and stuff.

FWIW, I haven't rooted the phone yet -- old or new.

It could just be bad RAM that causes the device to crash and shut down when reading corrupted memory -- much like what PCs do when equipped with faulty RAM chips.

If it starts happening again, I'll eat my words and update you guys.
[Captivate Q&A, Help & Troubleshooting] checkers2884:
You make valid points. How long has it been since you got the new phone? I'm thinking of exchanging mine just to be safe.
[Captivate Q&A, Help & Troubleshooting] ieee1394:
Mine hasn't done this again since the very first time. The only thing I've changed in the meantime is to change WiFi settings so that radio never turns off while its within range of a known AP. Just as an FYI, doing that will also wildly increase your battery standby time: with WiFi at the office and at home, I can get over 24 hrs of standby time. 3G really kills the battery, especially if you're in a marginal area as I am.

Now, taking that statement into consideration, perhaps its some process that calls out to the Internet and hangs badly when it can't connect? I know the first motivation is to start installing apps on these things when you get them, and some of those apps can be configured to update automatically...the only app I have running that updates automatically is ActiveSync. I haven't turned any other autoupdates on.

From observation, I'd say that these devices don't handle network outages particularly well. Which is a shame. I've even seen certain sites crash the browser.
[Captivate Q&A, Help & Troubleshooting] zorphnog:
I exchanged mine exactly one week ago for this exact issue and I haven't seen it happen once. Mine was shutting off 1-3 times a day on average before I exchanged for the new one. I definitely think there is a hardware issue with certain batches of the phone. Perhaps bad RAM as you suggested.
[Captivate Q&A, Help & Troubleshooting] astrocrep:
Can you explain a bit more about this wifi settings.

Thanks,

Richard P.
[Captivate Q&A, Help & Troubleshooting] ieee1394:
If you go into your Settings->Wireless and network->Wi-Fi->Menu->Advanced.

The default behavior is to turn the radio off whenever the screen goes off. That forces your device to switch back to cell service. WiFi uses much less power. I don't want to hijack this topic so that's all I'll say about it here....but perhaps loss of a data signal is a contributing factor to these shutdown problems.

I bought my captivate on 8/8/2010 and so far, I've experienced the phone shutting down on me once - which was last night.

My phone is completely stock, meaning it's not rooted or anything.
[Captivate Q&A, Help & Troubleshooting] eatkabab:
It only started happening after I did a factory reset to fix the batt issue. well it did fix the batt issue...
[Captivate Q&A, Help & Troubleshooting] Jack45:
Happened to me a short while ago for the first time. I read all of the pages in this thread and there does not appear to be a common link to this problem. From where I stand, this is a very serious issue. I will not reset, I will not exchange. If there's no guaranteed solution discovered in the next few days it's over for me. And as I wrote on another forum, I've been a supporter of the device after getting it on day one.
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
I would love this as well, I think it would help everyone here. Because if it is a hardware issue that is fixed with a specific batch of phones, then when we go to the store to replace it, we should be able to tell off the bat if its fixed or not.
[Captivate Q&A, Help & Troubleshooting] danix180:
OK,

[Captivate Q&A, Help & Troubleshooting] Sulphur4724:
Just noticed this. Using an app called system panel and reviewing it's graphs over periods where I have randomly shut down it shows a 50% drop in battery just before a shutoff. I don't mean it shuts off at 50% I mean that 50% of whatever is left at any given time it shuts off just... drops. No slope at all, 75% at one second 37ish% right before it shuts off. When I start it up again it's the same thing in reverse. It will show the battery at 37ish% until it starts up and then shows 75%. Same way, just a big jump, no slope. If I just reboot or turn the phone off it doesn't do this. It shows 75% both ways. Only shows this on a random wtf shutdown. Needs more investigation I suppose, but interesting none the less.

But I also have one of those batteries where it can be 60% and reboot it's 40%. I'm reasonably sure my battery is fubar for a few reasons but thought I'd throw this out there and see where it sticks.

I've had the phone for 3 weeks and it never happened until now. Reading through these threads, seems like there is no real fix. I cannot use CKA because it chews up my battery like mad!

What should I do, XDA?
[Captivate Q&A, Help & Troubleshooting] kegobeer:
Get a replacement. It's less than 30 days old, so take it back to the AT&T store and get a new one. Mine is almost 3 months old, so I called AT&T and got through to the warranty department. My replacement will be here tomorrow.

I was told that Samsung knows about it, and fixed the hardware problem. The refurbs and new ones shouldn't have the hardware defect anymore.
[Captivate Q&A, Help & Troubleshooting] ajm786:
Do I have to put the phone back to stock, or will they just replace it outright due to this known hardware issue?

Also, how do I know I'm getting a phone from this supposed "newer" batch? I don't want to run into this issue again.
