Back-up Unlock phones lock screen

There are two possibilities. The first is to continue to try and unlock the phone with the wrong pattern until it prompts you for your password. On many phones you will then enter the Google account password to unlock it. Be advised, however, that on SOME phone, too many bad attempts will also issue a factory reset. I'm not sure where Samsung fits in there.

Another option would be to log into your Google account on a PC and use the find phone option to issue a lock request. Then I believe the only way to unlock it would be the account password and not the pattern.

 

It is usually 10 or 15 consecutive bad attempts that bring up the prompt for Google credentials. I'm not sure if Samsung would change that.

To log into your Google account on your PC (not your phone) go to https://myaccount.google.com/ and login. Yes, you want to issue a request for a remote phone lock. Then you will need to enter your google password on the phone to unlock it. This should get you past the pattern lock.

 

If you go to https://www.google.com/android/find? and select your phone from the list of available devices you should see an option to lock the phone and sign our of Google.
