Just recently, version 2.11.312.0 of WhatsApp, a popular messaging app for Windows Phone 8, was rolled out to the masses. Now, in an internal Beta version of the app, the developers are working on a new feature that lets you clear all of your messages with a few taps.
Currently in private Beta, this new build of WhatsApp allows one to clear messages older than 30 days, or even 6 months. You can also be daring and clear all your messages. This new feature is slated for release in an upcoming update. Another leak shows that users will be able to save profile pic of any contact.
