I recently updated android version to 4.4.2 on my Nexus 4. After this update my apps like "watsapp", "LINE", "VIBER" are having connectivity issue when connecting through WiFi, But I could open the browser and could access the web pages. I didn't have this issue with the previous android version. Can anyone suggest how to resolve this issue.
