For the second time in five years my hardware has healed it self.This time my year old cell phone was taken to my retailer.I told them it froze and I could not make calls. The tech told me it could not be fixed,A few days ago I recharged the phone and it now works The phone is no longer online but it does work.This has also happen to a computer a few years ago. Do you feel over time the chip or software heals itself. Can anyone tell me what may have happen.
