I know there are many threads on this already. 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. Any insight?
