Hi all. Still getting to know my S4! My query is this:- I use Whatsapp messenger, and today it updated via Play store. A few minutes later I got a "warning" msg that it has been closed due to possible security issue that may be resolved by updating the Samsung Security Policy. however when I try to update, i am informed that it has failed due to network issues. Is anyone else having/had this issue? How do I resolve it? Or will I be able to update the policy eventually?
