How delete a Google account?
If an account is added, the account is shown in “Accounts & sync” of “Settings”, where you may also add another account. To delete an
undesired account, go to “Settings” → “Privacy settings” → “Factory data reset”. Your tablet’s internal storage, downloaded apps, etc. will
also be deleted, except the info in your flash memory. Be careful before you carry out this operation.
