    My Lumia 520 has become very slow after the Denim update. Apps which opened immediately earlier now take, say, 5 to 7 seconds to open. Whatsapp keeps closing on its own and opens also very slowly.

    Yeah... Make a good backup and reset.

    For best effect - use the Lumia Software Recovery Tool so you know you have a clean install of the latest software for your phone.
