Wifi issue on my Nexus 4 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.

The reason seems to be If you have cleared your Google Service Framework data to recieve the update, it will change your device ID that google uses to recognise your device.
