shut down your phone and press vol up and power button together until samsung logo appears leave button then Android recovery screen will appear scroll down to wipe data factory reset from there but first backup ur entire data it should work then and yes this time after fresh new form kindly update phone and setup samsung account and password lock unless u do it because factory reset when u choose will ask for password that u had set when u first configured ur device and that lock is used to unlock ur phone after u enter ur password then only factory reset will proceed it's a security feature to prevent anyone from wiping ur phone away other than you 👍👍👍👍👍👍👍
