I have had my desire HD for about 18months now and it has started to do some strange things. About a month ago it started randomly turning itself off and then reseting the time and date back to 1980. I have removed the battery and sim card covers and cleaned and adjusted the copper circuit prongs, it seemed to work better for a couple of days but now back to switching itself off. I have also done a factory reset thinking it could be a malicious app. I am getting really frustracted by it now and I am starting to think that the best option would be a new phone and a sledge hammer for the DHD........ Anybody have any ideas what could be the cause of the problems and any solutions?
