I have had this phone for about 2 months now and haven't had any problems with it till now. I was texting while the phone was plugged in and charging, when it suddenly froze and went completely black. after about a minute the screen came back and it said that the phone had and error and to wait till it recovered. It has been about a half hour and It hasn't improved at all.

Any thoughts or suggestions?
It says in red letters that

A system error has occurred
