Is to read the manual for any reset features. I reset the device and hope. If that fails it needs repair. I'm not there to hear your dialog with Samsung but they do tend to hang up if folk get upset.
Does anybody know how to test the LCD display on this Camera as after six months of use the screen went blank and would only display when set to night mode. I have tried contacting Samsung only to be told that there is no service agent within 100Klms of me and then they hang up, I've been trying to get this repaired but the after sales service does not exist for Samsung products as I'm having similar problems with a Samsung duos GT S6102 I would not recommend Samsung to any person in Australia
