Hi, Got my new S5 AT&T unlocked phone. I was able to connect it to my home wifi and tried to use the playstore to download apps. My problem is i can't log-in to my google account in order to use the playstore. Don't have any issue on my existing google account and this is what i've been using on my other android gadgets. This is the screen message everytime i tried to sign-in to my google account "Can't establish a reliable connection to the server. This could be a temporary proble or your android device may not be provisioned for data services. If it continues, call Customer Care". Need help, TIA.
