Dear user now I will going to explain why Google play not work but other application work with Internet.This problem are only faced by root android user because with root you can install any unauthorised app which is restricted in Google play.

The latest update in Google play is that if any one try to access it forcibly that means if any one try to hack or crack Google play to purchase the application free .Then in order to save it from forcibly used, Google play generate a command which block it self to use Internet so that is cannot be used to get hack.
