WhatsApp for Android smartphone users has updated the privacy setting, wherein the last seen time of the user can be hide. One can turn this off using a couple of steps on its settings.
 
The developers are planning to update the Android version with an official feature which lets you hide the last time you opened the application, from WhatsApp. All one have to do is, download the update numbered at version 2.11.169. The application only works with smartphones running on Android Jelly Bean 2.1 or above.
 
For hiding the visibility of last seen time, go to the Menu button and from there, Settings then Account and finally, Privacy. Than one can choose to have their WhatsApp profile picture, ‘last seen,’ and/or status visible to contacts from the address book only, everyone or nobody. By doing this,  one won’t be able to see the other party’s last seen time.
