Hard Reset and Factory Reset with Samsung Galaxy Secret Codes
Another cool thing that you can do with Secret codes is Hard Reset or factory reset your phone straight from the dialer of your phone without going into menus or fidgeting with button combinations.Remember only dial the following if you want to reset your phone:
Factory Reset: *#*#7780#*#*
Returns your phone to factory settings as when you first bought it or removed it from the box as all personification and information you entered will be deleted. I personally do this if I am selling a phone or need to refresh my device in case its running slow.
Hard Reset: *2767*3855#
This will reformat the firmware removing everything such as files and setting and personalisations that are stored on the phones memory. This is great for fixing issued with your phone and its functionality.
