Samsung galaxy series provide us a facility to secure your privacy by setting up a password,
but sometime this facility may be a problem for us when we lost/forgot the password.
We then have to go to care and ask them to break the password but by this simple trick you could do it yourself. ( #NOT_A_JOKE ☻). So just not explaining and talking to much I'm coming to the point.. :) Here is how you will unlock your samsung galaxy phone by your own.
Secret Method
It is very simple folks! You just need have to dial a code and the phone will be formatted.
This is the code *2767*3855#
Just dial it and see the magic.
