Phone turns itself off, FREQUENTLY

I have an extremely irritating problem with my Samsung Captivate.

It randomly turns itself off. Regardless of how charged the battery is. To give a scale of the problem, I have noticed this behavior 14 times since Friday afternoon - and to be fair it would probably would be happening more if i'd notice sooner and turn it on again.

It happens when the phone is idle (which makes it useless as an alarm clock) and also when the phone is active. Since friday, I have not been able to have a phone conversation on it for more than about 45 seconds before I notice that the person I'm talking with is not responding, and I check only to see that my phone is actually OFF.

I installed the system update, checked to see that the battery and sim card are in securely, nothing seems to help. A quick search online shows that a number of people are having this (or similar) problem, but nobody seems to have a solution. Some people have suggested that it may be related to live wallpapers, but I do not use those. Does anyone have any ideas?

If the battery is seated snugly then it sounds like you've got faulty phone.  Have you tried to check if the battery is slightly loose inside the case; like you shake it around and see if the battery comes away from the terminals enough for the phone to lose power?

Not sure where you stand in the 30 day return policy, or if you have insurance, but I think you might want to consider taking it back and exchanging it.  Also, Was this happening before the update occurred?

trade it in.  get a new one since you've only had it for 4 days.

There is now a solution:  Captivate Keep Alive app.  Just posted on AppBrain and it really seems to work for me.  Spread the word.

Have spent the last 2 weeks with this problem.  We've reset the phone twice to factory specs, and it still turned off from standby.  I received a new battery today and it still turned off.  The Android rep today had me factory reset and install Android Antivirus.  No shutdowns since then.  Of course, I haven't downloaded any apps except for antivirus, app killer and Facebook.  They are still sending me a new phone.  The Captivate Keep Alive app worked some, but it ate lots of battery.  I believe it's app-related, but not sure. 

You could try what the person who posted above you did^^


Sounds like this is becoming a more prevalent problem.  I would contact Samsung and see if you can't get them to replace the phone for you.  There should be a 1 year warranty with them.  If not, get an insurance plan put onto your plan pronto and make a claim.

This is an issue that I've been having too.  For me, it seems like it would happen at almost the exact time every day, at least once a day, but never more than twice.  I had been thinking that it was a re-booting feature, but I see that there may be more to it than that...

OMG I'm sorry to hear about the power off issues so many are having. I've had my Captivate for 5 months now and it's only turned off on 3 rare occasions. Few and far between. I won't complain. I hope a real fix comes out for all you good people.
