If you reset a phone that is linked to a Google account, you must use the same account and password to “unlock” it in all recent versions of Android. It’s known as FRP (Factory Reset Protection), and it’s designed to make stolen devices less appealing.

Simply input an incorrect pattern or PIN five times at the lock screen post, and you’ll see a “Forgot Password” button. Enter your Google account username and password (the one linked to your phone) after tapping the button.

Go to Settings. If your phone is in tab view, go to the System page. Select Security. Uncheck Reactivation lock. Review the warning about disabling reactivation lock and tap OK when you’re ready. Enter the Samsung account password and confirm your choice by tapping Confirm.

To delete a Google Account, go to Settings > Accounts > Select the desired Google Account and press Remove Account. Make sure you select the account by tapping Remove Account then Confirm Removal.
