Pictures released by Tizen Experts show a WhatsApp client running on the Z1, with the app expected to be loaded on the Z1 at launch. The app looks exactly the same as its Android counterpart, though since Tizen doesn't officially support emulation for Android apps (if it did, Tizen would not be a very good alternative to Google's dominant mobile OS, as developers would simply launch their Android apps instead of making native ones), we're probably looking at a fully native client.
The Samsung Z1 is set to launch in India on January 18, and that is when we will find out whether prospective buyers of the device will have WhatsApp out of the box or if they will have to wait for the app to be released later on.
