You need to first register/Login with a google account before you can access the google play store or any other google features or apps. If you do not have a google account, you can create an account for free using an email address. Wait for the email confirmation then activate account via email and you are good to go.

Thank you

Method one: Google account unlock

Necessary condition: Before the locked machine is set up, login to google account, account password is known, and the mobile phone can be networked.

1. Input the password at random 5 times, the system prompts 5 times of input error, retry after 30 seconds;

2. At this time, the "Unforget Password" will be displayed at the bottom of the unlock interface, and you can unlock it immediately by clicking the Google account and password you have set before entering.

Method two: Clear data to unlock

Advantages: no restrictions, apply to users without important information.

1. Press and hold the volume up button + power button at the same time to enter Recovery.

Now this google id on the top right corner of the page would be displayed as [email protected].

3) Type in the google id, thats visible on the right hand top corner of your page ([email protected]) into your galaxy s handset locked page, and type in the password.
