Help my new s4 phone randomly rebooted itself?

[phonefanatic89]

hi guys I've had my s4 phone 2 weeks now I've never had a samsung before but I love this one so far
but something does worry me, the battery was about 30 percent from charge, then the phone rebooted itself.
For a new phone this worries me as I feel the phone is faulty I am just wondering has this happened 2 anyone else?

Mines hasn't experienced that at all. If it doesn't do it again then don't worry about it. see if it does it again. I also have a S4 for bid. Highest bid is only $305.00. Free shipping.
