Hi! I am new to using my Zeki Quad Core 7" tablet, which a friend gave to us. To begin with - here are a few questions: (1) How do I get our neighbor's name off the tablet (if required in order for me to be able to logon to sites, like google chrome). And how to I put my name in it instead? (2) My google chrome password contains an aterisk. But I can't find an aterisk in my keyboard in the pad. Do I need to change my google chrome password, in order to be able to logon to my Zeki tablet? (3) I don't know what is the model number of my my Zeki Quad Core 7" tablet. How do I find out what it is? (4) What I should when I get the error message of "I'm sorry, but Google has to shut down." How can this problem be fixed? If you can answer any of these questions, I will be thankful!
