Hello, my name is Rusty. When your account is hacked, it's not necessary to change email providers. Gmail is pretty secure, all you have to do is change all of your passwords. That means Facebook, bank passwords, etc... The way hackers get passwords is by first hacking into your email, then sending a "forgot password" request to your email address.
Android tablets work with a Google account. On your computer, go back to your old account and change the password ***** If you have deleted the account, that's ok, just make a new one. Sign into Gmail on your tablet, and you'll be able to access the Google Play store. Change your Gmail password ***** every three months, and use numbers and symbols to make up that password. That way a bot will have a harder time getting your password.
Once you sign it into a Gmail account, either the one you were using or a brand new one, it will return to normal. Do not use another Gmail account that is used on another tablet, or you'll see your contacts and apps do some strange stuff.
