Help Phone Shutting off randomly?

I ended up having to return mine for an exchange. Mine was so bad that it turned off every single time it went to sleep. The only thing i did to mine was root it and remove some AT&T apps, I didnt have time to install anything before it started acting up. Since I got mine through Letstalk.com I will be without my captivate for at least a week. I sure hope the new one doesnt do this too. It sucks that this had to be my first post!

At first I thought it might be a problem with inadvertently pressing the power off button, but today it happened after I'd set the phone on my notebook in a meeting. I know darn well the button didn't get pushed then! I took it over to AT&T and exchanged it, no problem. Hopefully no problems with the new phone :-)
 
Mine had gone just a little over 24 hours without turning off. After my last meeting, phone was off. Looks like I will be getting it swapped... :mad:
 
Mine did this for the first time today. Had the phone since launch. Fixed by removing the battery.

Has anybody made Samsung aware of this?
 
4x this am now. i changed my task killer to agressive with screen off last night. changing back to safe with screen off. maybe there is something getting hit

no issues since ive neen in safe
 
I started having this problem also. Didn't until after having the phone for a week. Nothing changed from stock setup other than adding a few apps from the market.
 
Add me to this list. Happened 2 days in a row. Once in the car and once while I was asleep. This is a problem. I use the phone as my alarm. How am I supposed to wake up?!
 
I, like all of you, have experienced this many times...I originally thought that it was me pushing the button a little too hard, but after paying closer attention to it, I realized it's not me. The phone just decides when and when not to be on. :mad:

If I don't see a fix, I will more than likely return it for a IPHONE. I really like this phone and wish it it didn't have this seemingly common problem.
 
Well... I just returned my Captivate and got another one. I only had the previous one for a week and it shut off on me many times. We will see...:confused:
 
I had the same issue. Me and my wife bought our phones at the same time about a week and a half ago. Her phone has had no issues. Mine would turn off randomly. I swapped mine out at the ATT store and so far (3 days) have had no issues.
 
As I noted earlier, I got a replacement on the 29th. It was doing okay, but I just had to power it back up after it shut itself off. Guess I'm about to head over to the AT&T store again :-(
 
This has happened to me twice. It was always when the phone was sleeping so I had thought that I accidentally shut the phone off, but I was pretty sure it wasn't normal. Good to know that I'm not the only one with this !
 
I have not experienced this once. I do not run any task managers and use TouchWiz. What about those of you who do experience the problem?
 
I've had my phone for less than a week. I love it (but have also had periodic GPS troubles).

I had my phone charging and was actually using a "sound machine" app for sleep. It just shut off at 2am and wouldn't turn back on. This morning, as a last resort, I pulled the battery and it came on charged 100%. This is crazy!
 
My vibrant has started doing some weird random reboot, its a really strange process. The phone becomes unresponsive, the screen goes completely black. I think its off, so I try turning it on, and again no response. Then suddenly, the phone starts at a state that appears to be a reboot, it is scanning all the sd cards again, and starting fresh. The strange part, the phone never displays the boot up screen, you know the T-mobile boot up screen, then that fansy rainbow colored S. It just stops responding, and goes to a black screen, and does a reboot mysteriously behind this black screen.

BTW, in the vibrant forum, other users are reporting random reboots too. So i don't know if this is a hardware issue, or a software problem.
 
Mine is doing this too. It has been happening about every 2 days for me, for no apparent reason. I'm not sure what the problem could be, but sounding like an issue with this many posts. Unsure if I should swap it or not at AT&T store. Phone has been working fine minus that detail.
 
this happened twice to me today. the first time was a few minutes after i unplugged it from the wall charger. the second time was an hour later after i unplugged the phone from my car charger.
 
My phone has not shut off by itself when Wi-Fi is not enabled. If Wi-Fi is enabled it will shut down. It did so 3 times in 3 hours with Wi-Fi on. I shut it off and have not experienced the shut-downs. Can some others try this experiment and post their results?

Well i got my replacement phone on Monday and this one has not shut off once yet! Maybe there was a bad run on the hardware. Now I can start to enjoy this phone.

I tried this but it still turned off randomly during idle.

What has seemed to work for the past 3 hours or so (it was turning off every 10 minutes) is I took the battery out and got the app advance task killer. I did have a bunch of apps going so I think that may have helped.
