This one for samsung android mobiles only.
Just Power off your android phone, after that press power key, volume key(+) and home button together till screen on..
then there will be option for factory data reset.. do it..
NOTE: All your data will be deleted..
then your phone will automatically power off.. you have to just power it on after factory data reset finished.. and complete your minor setting.. your handset is READY FOR USE..
Thank you
