I have four Galaxy S phones in my family and three of them are experiencing random phone shut offs. I don't always realize it turned off until I go to do something. One time it shut off 5 minutes after I had restarted it. Sometimes I can go a few days without it shutting off and others it shuts off multiple times per day.
As far as I know I don't have any apps installed, actually I got rid of the one I did.
Is there any known update or something to resolve this?
