Hey, a few days ago I started my first serious issue with my phone (I don't consider the lag or gps problems serious).
While being in cell standby (and I don't use it), the phone has restarted completely randomly 4 or 5 days in a row now. I have no idea what's causing it. I'm prompted to enter my sim card pin again upon reboot.
Has anyone else had similar problems? Are there any ways to fix this? :|
I'm using the official firmware available (I haven't flashed), XXJF3, and the phone is not rooted.
uninstall whatever is causing it
do you remember what have you installed recently?
just uninstall the latest Apps that you installed in the last few days
I have the same problem, only in my case it happens once every 2 weeks...
Because it happens so infrequently I haven't done more research on this issue. My idea was to try to determine what is going by going over Android logfiles, but that is from my assumption: everything is logged under Linux. Not sure if this is the case for Android.
Anybody any suggestions on which logfiles to read/examine?
Experiencing random shutdowns ever since moving to Congnition. This morning, just to clean everything out, I did an Odin Master Clear and used Odin to flash Cognition 2.2b6. About an hour later, I had my first random shutdown.
This doesn't appear to be totally random. It only occurs when the phone is in screenlock mode, such as when it's in my pocket or sitting unused on my desk. I will go grab the phone to turn on the screen, and realize that it is shut off. So, I have to long hold it to boot it back up again.
Is anyone else experiencing this issue with Cognition? It seems to occur about once an hour for me, and sometimes it will go hours without shutting down. Also, it never appears to shutdown when I'm using it, but maybe that's just by chance.
Any other ideas how I could fix this? I've already Master Cleared. Could it be an app that doesn't play well? The only apps I've installed so far is Launcher Pro, Beautiful Widget and Titanium Backup, of course.
Are you serious??????? You open a thread just to ask this question?? Why not ask in the Cognition thread?!!!!

Because it has a trillion posts and my question would be swallowed up in about three minutes.
Same here but i dont think its cognition its the froyo leak. It was happening to me with the stock leak too so i know its not cog. If u think it is try the stock leak. But id wait to see if it still happens after offical build.

I would use Odin One Click and go back to stock for a few days and see what happens.
If your restoring with Titanium Backup, don't restore settings.
bet you don't get a solution before they lock this thread
No random shut downs here on either cog 2.2 beta 5 or beta 6

+1 b5.5,b6,b7 No shutdowns. Had them all the time on 2.1 JF6.
my random shutdown issue STOPPED as soon as I started running Cognition ROMS. DG was a lifesaver for my phone.
If your having them.. keep it on stock - if it repeats - you have a dud and need to get it replaced.
And when you flash it to stock.. don't load anything on it to see if it stops the random shutdown.
**edt... and um wth is this in the dev forum and not the Q&A?
Try this if you havent
No problems here either. I have been with Cog since the beginning and have never had this problem. I had it on another ROM from another Dev and immediately came back to Cog. I am now running Cog 2.2 Beta 7 and Love it! Fastest phone I have ever owned, very stable and GPS finally works!!! I would recommend flashing back to stock with Odin, doing a master clear and then installing Cog beta 7 via Rom Manager. I dont deal with Odin when flashing ROM's, only when going stock.
Hope this helps!
hey... i thought i was the only one getting the random shutdowns. i think i've been getting it since the first month of owning my phone. i get it 2-3 times a day. 1 if i'm lucky. i don't blame it on cognition's rom, tho... dunno what to do or who to ask about this problem.
but as for flashing back to stock and then the latest COG rom, i have tried that, but it didn't work...
I haven't run Cog beta7 for very long, but I can tell you I've never had a random shutdown for the entire time I've owned my phone (bought 3 days after release).
I'm tempted to tell you to try a different battery or something of that nature...

i would agree swapping the phones battery or the whole thing would be the way to go...
This is not an unusual issue. Seems even Moto apologized for it in their Froyo OTA for the Droid. Moto says a fix is coming. I would suspect it is a Froyo bug and something that will be worked out in a future update for all Froyo handsets.
No random shutdowns for me on stock leaked of any of the 2.2 cognitions
I've been having random shutdowns on Stock 2.1 Eclair for a while, there was another thread poster about this in the Q&A.
Even after I flashed to cognition b5.5, I get them, and with the same frequency. Sometimes I get 2 or 3 a day if I'm extremely unlucky, usually I'll only get one like once a week. I don't really find it to be too big of an annoyance.
I think it has something to do with an app, and not the phone itself. If you're getting them consistently 2-3 times a day then I guess you should just master clear, go back to plain stock, and then reflash cognition if you want to.

PEBCAC problem "me thinks".
Its device specific, I had one that did it, they gave me a new one.

That definitely seems to be the case. I had a Captivate that was running JF6 that was completely stock other than being rooted. It started randomly shutting down within a couple of days. I thought it could be an issue with rooting it, so I flashed back to stock and used it like that for a few days. The random shutdown issue didn't go away, so I took my phone back and told them it was defective. They gave me another one and I haven't had the shutdown issue even once, through JF6, JH7, JI6, and Cognition 2.2 Beta 6 and now Beta 7.
This seems to be happening with every ics rom I flash. I first flashed ics to my phone when it first started to be ported to the Captivate.
My phone has suddenly started rebooting every so often (every 20-30 minutes.) My phone usually does this when it gets to about 60% battery. I have already tried calibrating the battery and using a different battery. Neither method has worked. Is anyone else having this issue or know how to solve it?
EDIT: meant to say shutting down not rebooting. Also it doesn't shut down on me while I use it, only when I set the phone down and the screen turns off.

That's generally hard to troubleshoot, but the first step I would take in this situation would be to bump up the lower frequency voltages. Of course you'd need a different kernel to do that. Try Glitch or Semaphore if you want. If you've never played with that stuff before, there is some necessary reading involved before you can know what to do.
This has been an on-going problem with Samsung Captivates, ive had that issue, Ive tried all the above. Including all the ROMs on xDA, and also different methods of flashing. And ive had no luck either. I went back to GB. If u do find a fix, let me know.
In my opinion, i think its our phones, some can handle it, and unlucky ones cant. Sucks.
same issue with me. the last four digits of my IMEI are below the cutoff point of phones who would eventually have the issue.
Every single ICS rom shuts off my phone randomly. ever since I went back to GB, it has been running fine. tried a bunch of stuff to, but nothing works.
While scrolling through my Nexus 6 apps, the phone froze and the screen went nuts. I had to turn the phone off and restart it. Samething happened a few hrs later....... Am i the only one experiencing this? Any troubleshooting tips? Thanks in advance.
Never seen that before. Are you on stock?
I was on stock and had it happen one time. A reboot resolved it. I think the SW thought I wanted to add all my apps as shortcuts.
Im also running stock. Havent had an issue until today. First time it happened, i had to reboot. Second time I just locked and unlocked the phone.
I've been getting occasional reboots every couple of days. I wasn't too bother by that, but since I installed the latest security update 2 days ago, my phone has been rebooting constantly. I think today I've had it happened close to 10 times.
I've cleared the device cache which didn't help.
Will try doing a hard reset soon.
Anyone else have had this issue and may be able to point out some options to try?
I'm wondering if this was update related or could it actually be hardware?

I would guess software - it's painful, but back up what you have - and write down all the apps you have. Then uninstall them one every other day, in order of least important apps to you. When the problem goes away, you have found the app causing the issue. If not and you run out of apps, then do a hard reset. Don't reinstall everything at once. Start installing apps, only a couple every other day or so. If the problem comes back then you know which apps...
