I bought the tablets from China, and if I want to add Google account (from Settings.Account.AddAccount) ther is no google account in the list.. There is only
Corporate IMAP POP3
tablet: x-302 of Dragon
kernel 3 April 67
and on tablet are no applications from Google (NO "Gmail", "Account Manager Google" and "Google Services Framework") It looks as if not installed (or forbidden) Google applications from the producer.
