While they are spending more of them time on app design, Windows Phone developers spend the least amount of time on de-bugging their handiwork. Android users spend 36.1% of their working time on exterminating bugs versus 24.2% for iOS developers, and just 19.8% for Windows Phone app writers. On the other hand, they spend the most time pushing out updates (6.3% versus 4.2% for Android developers, and 3.7% of iOS writers).
