What do you think its the most underrated windows phone feature is ?

For me it would be the ability to switch between the dark and light theme.
It can literally change the look of your phone by the flick of a slider.

I'd say the email apps. They are so incredibly simple, but so useful. They have everything you need while all you see is some text and not even a slick UI. That's the pure power of WP

Pin almost everything to your home screen. Best feature for me.
