how to reset samsung galaxy s3

If your Galaxy S III keeps freezing, you’ve forgotten the security codes or it just doesn’t work, take it back to factory settings.

Important: This wipes everything on your phone, so if you’re not locked out try backing it up first. This won’t wipe your SIM.

 How to do it

Step 1

Turn the phone off. If you can’t, remove and reinstall the battery.

Step 2

With the phone still off, hold down the ‘Power’, ‘Volume Up’ and ‘Menu’ buttons at the same time for about 10 seconds. Release them when you see the green android logo. This’ll get you into the unlock/reset menu.

 Step 3

Scroll down and select 'Wipe Data/Factory Reset'.

You can use the volume buttons to scroll up/down and the power button to confirm selections.

 Step 4

Select ‘Yes - Delete All User Data’.
Step 5

Select 'Reboot System Now'. The phone then reboots to factory settings with the security lock removed.
