Have this problem with my phone, happens random (i think) but quite often, almost every day and it gets really frustrating.
I press the Call Button and i won't do anything until I restart the phone(I have to remove the battery to).
it is not a problem with the Call Button because it works until i get to the calling part.
I tryed the Option>Voice Call - but still nothing.
I want to know if this happened to anyone else or if it's a software or hardware problem.( my guess is that is a software problem)
Thank you
