Re: Random shutdowns
My phone's shut off a few times by itself. It's only happened when I don't turn the screen on before I unplug it from the USB. I was using setcpu and I had it set to 400/200 mhz while the screen was off so I raised that a bit and it hasn't happened since.

I have also noted my phone has shut down quite a few times during the day. I am at work and when I go to check my phone it is off. I am using Advanced Task Killer, but what is strange is that one day it will go off 2-3 times and the next day not at all. So I am completely confused to what is causing it. Any ideas?

Well, I've gone 3 days so far without another crash. I went into Settings->Sound and Display and disabled Power Saving Mode. I had seen this suggestion on some of the other threads, but I had also seen replies stating that people tried this and it didn't work. I'll update again if I notice another random shutdown.

Well my phone actually never shutdown but it did a reboot 2x since I got it, kind of freaked out, but has never shutdown once at all. Sometimes it lags coming out of sleep but still no issues and a little app lag.. Otherwise my phone is perfect.

I've had my phone shutdown three times on me now. The first time that I noticed it was when I woke up, with the phone still connected to the charger. After restarting it, I went to do some yard work and when I came back it was off.
Today, I've had the phone sitting on my desk most of the day. It hasn't been connected to the charger, but after hours of non-use, it was off.
I don't have any task killers or setcpu installed. I really haven't done much with the phone yet.

Well mine just shutdown I guess. I was on this site all of a sudden screen went black. Then a big battery shows on the screen. Then it shut off and I had to turn it back on. My battery its fully charged. Advance task killer is set the way it has been since I installed it. No new programs have been added to the phone. I am coming on three weeks having the phone also.Never forget my Brothers and Sisters that gave their lives on 09-11-01. FDNY/EMS, NYPD, PAPD and the Pentagon. Also those who are still dying to this day.

My first phone started shutting down 2 - 3 times a day about 2 1/2 weeks after I got it. My son, who got his the same day, hasn't had it happen at all. I returned mine for a new one (no hassles at all), and the new phone hasn't shut down on its own yet.

Over at the Xda forums they're saying it's a guts issue. Some phones are having problems and some aren't. And some are exchanging them and not having issues anymore and some do have issues. Through the thread they've ruled out it not being apps, battery, launchers, etc. So basically it's come down to being a hardware issue and it will only get worse.

Mine has shut down several times over last couple of weeks. Had if for almost two months. Mostly shut down at night on charger. Today phone was not moved for three hours and had shut down with 42% battery left. I am running Advanced Task Killer but don't think it is the problem. After update was install, all apps had to be re-installed. The phone shut down before I re-installed ATK.

Well I went through this for the last few weeks. Phone started with once a day and by the end of the week it was off more than it was on. This morning, dead. Phone would not power on. Connected to charger. . . no go. Took it back to bestbuy and they are shipping it off. Really hoping its toast and they just give me a new phone. . . LOL!

It happens to my Samsung S Vibrant and I *think* I can reliably reproduce the issue, at least on my phone.
1. Go to a spot where you know it has failed, for me this is my office because it has bad reception and it seems to only shutdown for me when there is bad reception.
2. Make sure 3G is turned on and open an application that uses data.
3. Wait for the phone to sleep, do not hit the power button or anything to make it sleep (not sure if this step matters)
4. Wait ~30 mins without touching the phone (You can play music with it while this is happening if you want, the music will stop to let you know it's failed)
5. Try to wake up your phone, it is now dead.
I'm not sure this will work for everyone but last night I could reproduce 3 shutdowns in an hour and a half. And reproduced about 7 shutdowns yesterday when my phone only usually shuts down ~2 times a day.
I'm testing out all kinds of software permutations (disabling stuff, installing things like Captivate Keep Alive). Nothing has worked so far, my guess right now is that the problem lies in the Pattern Unlock feature so I have disabled it, I read that on a forum somewhere.
My guess is that if you have too much running in the background it might take up too much cpu or ram so that when the phone tries to come out of sleep it can't get enough CPU power to come out of sleep and therefore gets stuck in a kind of limbo. This theory could then be releated to the SetCPU problem when you set the CPU too low when it sleeps the issue occurs.
Moral of the storey is I have no idea what's going on, but please post if this works or doesn't work. Maybe it will shed some light on the issue, or you can tell me I'm wrong so I can give up.
Luckily I'm not past the 30 day mark and I'm exchanging for a new Vibrant tonight. Wish me luck!
