Theresa, From forums I have read your issue could be corrupt Apps/software and it is suggested to do a factory reset to get it out of the freeze. Below are links telling how to do a factory reset( you will lose all stored data when doing this reset). Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
