The saddest part of it all is that the competition that Windows Phone provided influenced a lot of consequential and positive improvements for mobile devices during that era.
Microsoft pioneered the idea of "pocket-to-picture" by requiring a dedicated two-stage camera button on every Windows Phone for a long time, which ultimately led Apple to configure the volume buttons to act as makeshift shutter buttons and put a dedicated camera button the lock screen. Both changes are now near-ubiquitous among Android phones as well.
Windows Phone was also very aggressive about keeping clutter out of the way by hiding irrelevant status icons from the top status bar so that the entire screen could be used for app content. Tapping the top of the screen would temporarily bring the full status bar into view. We now see this effort making its way to iPhone with the iPhone X/XS "ears" that only show minimal status information and encourage apps to fully use the space available on the display.
