Samsung Captivate :: Phone Randomly Shutting Down After Updates
Sep 25, 2010
Ever since I've updated my phone shuts down randomly. Maybe once every other day, sometimes less. It would be a huge issue but my phone is also my alarm clock for getting up for work at 4am. I don't have any app killers, or battery savers installed. One thing I did notice POST update was, when you go into the running applications menu. The uptimes on the system apps seem to indicate the phone shuts them down to sleep or something. Several times Ive noticed, that even though my phone has been on for several days, the system apps have been running for 5/ 8 hours.

Has anyone else experienced trying to wake your phone from sleep only to find it has been powered off? Strangely, this did not happen the first 2 days, but started after charging the phone fully for a second time. Could this any way be app related? I've only downloaded a few so far such as ATK. I checked my phone right after writing this, and what do you know, it turned off....

So I got my phone a week ago or so and it just now started having problems with the GPS and randomly shutting off as well as the battery life being drained within a couple of hours from fully charged. Im guessing I should exchange my phone for a new one within my warranty period. Do I need to bring the original box and everything along with it to exchange it?

There seems to be a solution for the random shut-down problem with Captivate: Captivate Keep Alive app. This was just posted, and it really seems to work! Give it a try. So far I've been up for more than 24 hours without a shut down event.

I got my Galaxy last week. Having a problem with it in the past few days. At random intervals it powers itself down. It usually powers itself up, but this morning it didn't....so I slept in for work because I had no alarm! I got the phone on Friday, and upgraded to firmware 1.5 straight away, so not sure if the problem is a firmware one or not.

Bought the Captivate on launch day. I had problems with the battery, phone restarting by itself, buttons at the bottom would not register when pushed. Took that Captivate back yesterday and exchanged it for a new one. The new one I got works much better. Little to no lag, buttons are working properly, and the battery is much better. Used it until about 3% of battery was left then put the charger in. Fully charged by midnight, unplugged it and went to sleep. Woke up this morning to find out the phone shut itself off last night. I woke up and tried to check my emails but the screen would not turn on. Held the power button and the phone turned on as if it was just starting it up. I bought my phone from a authorized AT&T reseller so I'm hoping they'll let me exchange it for another one again.
I called Samsung tech support but they weren't much of a help. They said I can send it in for repair or take it back to where I got it for another exchange. My phone is not rooted and not tampered with in anyway. I downloaded all the same apps for it which were only about 6 so far. The only new one I did download was one of those Sense Digital Clock ones and put the widget on my home screen. Other than that the phone is set up just like my previous one. I deleted the Sense Digital Clock app so maybe that was the culprit? I really do not want to take this one back again as the one shut down is the only problem. I'm going to wait a couple days to see what happens. My 30 days are up on the 17th so if it keeps on shutting down I'm taking this one back.

My phone shut off randomly for the first time this morning luckily it didn't shut off early in the morning as I use my captivate as an alarm clock for my 8 am class. Anyway, I was just wondering if I should be worried? I've only had it for two weeks so I can still get a replacement phone but up until today I had no severe problems. Gps worked fine, battery life was good. I do experience some lag at times. For example, I'll click on messages and I'll have a black screen for ten seconds until my messages come up. Just wondering if I should be worried since it shut down for the first time if I end up having to get a replacement phone I feel like I'll only have the same problems since this is a common problem. I don't want to have to get an iphone, to be honest, I played around with it at the apple store the other day and I wasn't impressed. The captivate has so much more features and the home screen on the iphone just bores me. But the iphone works straight out of the box.

A few times a day my Evo will shut off randomly and turn right back on. Does anyone else have this happening to them?

I am running Nexbeast 1.1 fabs release clocked at 1.25ghz and I've dropped my phone maybe 4-5 times. None of them were big falls but the 3rd or 4th time I dropped it and all the times after that it has turned off. Anyways, whenever I do something for an extended period of time on my phone It freezes up. Seriously even if I'm only on it for 10 minutes. I can't do much without having this problem at least 1-2 times a day. Is their any fix to this? I don't recall it doing this on 2.1 builds. Could that be it?

My screen will go blank, like it went to sleep but what actually happened was it just simply shut off! I installed two logcat applications, but I don't know jack about reading logs I want to know what causes these shutdowns The latest ones happened between 6:32-6:33AM and 6:54-6:55AM (it's 7:26AM now, my time).

A few minutes ago my signal just showed no service for the second time. It was totally random, just like the last time and I don't think it's an AT&T problem because I was stationary in my house, where I've never seen this happen on my past devices. (Happened a few times on the iphone, but it only showed searching for about a second, then it came right back). On the Captivate it will show no service and won't come back until I reboot the phone. I'm not in a fringe service area (usually have 3 bars of 3g). Has anyone seen this happen on theirs? I'm trying really hard not to return it, but some of the bugs are getting pretty annoying.
I'm going to install CT Scheduler and run a reboot every morning. If it happens again, it may be going back...

Does anyone know why my GPS icon on the top toolbar of my phone would be running randomly? I have no apps running that would require it to come on and the only way to get it to turn off is to power the phone down and then turn it back on. It doesn't bother me.but I do believe it is running my battery down faster then normal.

My notification volume always seems to be adjusting by itself. How do you stop it? It can be my notification volume for gmail, text, meebo, or the notification volume in general. Is it something that I am doing that causes it to lower? or is there a way to lock the volume?

Is there an app that will randomly change your home screen and wallpaper to a different one at some pre-determined interval, say every time the phone restarts? There are so many cool looking home screens and wallpapers that I can't make up my mind. It would be nice to select a bunch and then have them randomly selected every restart or specified interval, kind of like shuffle on a CD player.

Hey everyone, I'm sort of new to this but I figured I'd give it a shot to see if anyone might have an answer.
This happens fairly frequently actually, but I'll be in an app (any app - it's not really particular) and sometimes it'll just randomly shut me out of it and return to the home screen. As it does this, the home button blinks and vibrates incessantly until I hold down on it - at which point it brings up a sort of mini-list of six apps (the last six apps I've opened, I suppose). Once I clear out of that list, then the phone resumes working normally.
I initially thought it had something to do with the memory and running too many apps at once, so I downloaded Advance Task Killer and run that occasionally...only to find the same problem occurring, sometimes RIGHT after I kill all the apps.
Has anyone else had this happen? Can anyone help me out?

I got a Captivate on the Rogers network here in Canada and I have some questions about some weird things I've noticed.
1. Some apps don't show updates when there are updates availableI use AppBrain and when I log in it says there are updates available for the following: Street View, Maps, Movies, Vlingo Voice, and Layar.I checked the version numbers of what is installed on my phone and what's in the market and sure enough the market versions are newer.However, when I open the Market application it doesn't show those applications in the list of downloads (and so no available updates).Also, if I go to the app page for Google Maps for example it shows an Install button, not an update button or "Installed".I use these apps so I know they're installed.What's going on?Is it because they came pre-installed?Can I safely update them through AppBrain even though the Market doesn't even show them as installed?
2. I can't find the Google Car Home app.I have searched via the Market and AppBrain and can't find this app anywhere.
3. Duplicate entries under Accounts and Sync.When I go to Accounts and Sync under settings I have two Facebook entries (both the same Facebook account though) and two Twitter entries (both the same Twitter account though).If I go in to each entry they have different settings. For example, one Facebook entry has just "Sync Contacts" while the other has "SNS setting", "Sync Contacts", and "Sync Calendar".Same with the Twitter entries. Why are these duplicates here?Also, when I go in to some contacts they have duplicate linked contacts from Facebook. So I have one contact who under linked contacts shows two linked contacts, one says it's from Facebook, the other says "Unknown" but I know it's also from Facebook since it has their Facebook picture (and they only have a Facebook profile and aren't in any other service like Google or Twitter).

I've been reading a lot of people getting errors while trying to check for samsung updates on the Captivate. I experienced this as well. I narrowed the problem to various Task Manager apps killing the "Device Management" task that is native to the captivate and launches after each reboot. When this task is killed, you will receive the "DM Initialization Error. Check your network or Sim Card" message every time you try to check for an update. Solution: Reboot and exclude the Device Management process from any of your task killers.

I am trying to track down a rogue application that seems to be receiving massive amounts of data. On the iPhone, I would use about 200mb/month due to WiFi at work and at home. However, on the Samsung Captivate, I can go from 100MB/month to 2+GB/month! I noticed huge amounts of data being used on my commutes to and from work.
On occasion, my home WiFi/DSL would get so lagged due to my Captivate being on the network that my son would complain and I would then put the phone in air plane mode. I reasoned that if it was happening on my WiFi network, as well as 3G, then perhaps I could using my router to log the activity to see what sites my phone was trying to connect to, then perhaps I could pinpoint the offending application.
My phone was connecting to a website that was part of a posting that was on facebook, which was only showing on the Samsung "Feeds and Updates" widget. I wasn't running the native facebook application at the time. I had the "Feeds and Updates" widget set to never update, unless I manually did it. Why was it trying to connect when it shouldn't have been? Don't know. Am I certain that this widget was the offending application? Not sure. Since removing the widget, I haven't had any bandwidth spikes.
PS. I tried Droid Wall, but it fails to work.

I am currently running a rooted Samsung Captivate. I have not flashed it or anything and am still running 2.1 with the firmware update (JH7). I rooted to get rid of AT&Ts bloatware which I did using System App remover. With Froyo on the way, I was wondering if a master reset would turn it back to stock (minus AT&T bloatware) and enable OTA updates again?

For a few weeks, my phone has been shutting itself off randomly for no apparent reason. I remove the battery, pop it back in, and it powers up normally. It's off now, I've removed the battery (for about 10 - 15 seconds) and it still won't turn back on.
