The Play Store gives me error code 491 after operating successfully for weeks tech support has offered me no solution or definition of the code. I have tried all of the solutions available online  on the tech support line for Google and ZTE the manufacturer of my phone. The only thing that works for awhile is if I completely hard reset my phone and reconfigure everything over and over again. I am frustrated beyond belief! Just for the record my phone is a ZTE zMAX Pro z981 Google get it together  you know what causes the error now you need a reliable fix for it that actually works
