I have been facing this issue from the time I started using Samsung Tizen Z3. Whatsapp hangs up very frequently on my Z3. None of the keys work on the whatsapp page. Infact the page remains frozen for a long time and when I re-open the app it again gets stuck.

Does anybody has a solution to this issue? Is it a common issue with Tizen?

Thanks

These are already being checked and addressed by FB and we hope to get fixes from them asap.
However we encourage you to post logs if specific hang cases in your device.  More logs will help FB devs to anlayse better and fix.

I have posted few logs in Tell us app. Please check them.

 Facebook has fixed many issues in a recent update.
restart your phone you will see notification for 35 MB Facebook service update. Once you install this update restart phone once more and check if the problem still exists or not.

@Koushen, are you still able to see WhatsApp hang after recent facebook service upgrade?
