how to hard reset your samsung smartphone
A guide on how to force your Samsung to factory reset
If your Galaxy smartphone keeps freezing, you’ve forgotten the security codes or it just doesn’t work, take it back to factory settings.
Important: This erases everything on your phone, so if you’re not locked out try backing it up first.
Switch your phone off. If it's frozen, remove the battery to turn it off then put it back.
Hold down the Power, Volume Up and Home buttons at the same time for about 10 seconds. Release them when the Android logo appears on the screen.
- To navigate through this menu, use the volume up/down buttons to scroll up and down and the power button to confirm selections.
Scroll down and select Wipe Data/Factory Reset.
- Scroll down and select Yes - Delete All User Data.
- Select Reboot System Now. The phone will then reboot to its factory settings.
