having problems with the home page S4 My S4 has been rooted 2 weeks ago,and today it locked up and I cannot do anything on it, cannot open settings, cannot receive phone calls, cannot send text messages. the home page is unresponsive, and when i try to press any buttons the only thing that comes up is a message saying "touchwiz in not responding". The computer is now not reading the phone. So not sure what to do, please advice. Thank you!

A friend rooted the phone for me, so not sure how it was done, and my friend is out of the country now.Did not change any settings.
Try factory setting option in settings.If it doesnt work,try updating it to next version os and again root it if necessary.I would suggest to just root it again it may happen that rooting process is not been completely successfull.
