I've found a solution to the random shutdowns, and that solution is simply the "TASK KILLER" because after a few shutdowns for the past week i wasnt convince that it would be the task killer that was causing the random shutdowns as i've already searched through the internet and every forum there is about random shutdowns with nothing mentioning about task killer being the major cause, so i was persistant went back trying to solve this common problem(with no luck), then after a week or so i suddenly wasn't able to receive any messages as i can only send it, so like every other Samsung Capivate owner out there with little to no issues, i googled the problem(like the random shutdows) read through every forum there is on the internet and finally came across this forum were someone posted that it was the task killer that can actually cause your phone not to be able to receive messages and to fix the problem was to simply take out your sim card, put it into another phone, turn it on(will simply work and show you all the text messages), take it back out from that phone, put it back into your Captivate, and problem fixed, but to make sure that i wasnt going to have this problem again, i deleted the task killer, few days even a week until now, no random shutdowns at all. So with that being said, the problem is the TASK KILLER!!! UNINSTALL IT!!! YOU DONT NEED IT!!!!
