To save the Windows mobile platform we would have to analyze what happened and what is feasible to do now.
So what happened? Windows Phone 7 to Windows Phone 8 was basically an experiment. The OS was fast and intuitive but often felt incomplete, mostly due to lack of 3rd party support. But over this time a following was actually building. 8.1 around 2014 would see the peak, if I remember right, close to 5% market share worldwide. Which is about the same time Satya Nadelle took over as CEO. He was obviously not interested in Windows Phone from the start. Shortly after, Microsoft apps were releasing on competing platforms before they were releasing on Windows Phone. Hardware production dwindled quickly and lagged behind the software. Even as the OS finally started maturing and 3rd party developers finally started making apps the higher ups interest was obviously not there. So with the obvious lack of interest from within and the slow to release, lackluster hardware... consumers aren't stupid.... we saw the death 3-4 years ago.
What would I do now to save the platform? First understand the market and customers. At its peak, less than 5% market share sounds pretty terrible but another way to look at it is, that is millions of people using a Windows Phone. And anyone in touch with their userbase would know these are actual fans of the platform. They would be loyal if rewarded for their loyalty.
With that in mind, I would say take a Blackberry-like approach. Reduce the budget, don't poor a ridiculous amount of resources into it. If Windows Phone was going to take over the market it would have happened already. But if we could maintain a solid 3-5% of the market, it could not only be profitable but we would be taking care of customers and with such a nice OS the potential to grow will always be there.
First step to regaining what has been lost over the last couple years would be to show consumers we still care. Release an updated line of phones. Budget, Mid, Flagship. Nothing too crazy but just repeat the Lumia 1520 type of release with updated specs. Make an announcement that Microsoft has not left the mobile phone arena.
With a new line of phones, a promise that we aren't killing the platform, and the ongoing push to build the UWP, I think previous customers would rejoin the ranks pretty quickly.
Once we're sitting back at around 3% market share, keep the hardware releases simple but consistent. Keep the OS updates steady but not heavy. Then use the next couple years to slowly make a push for developers to port apps to UWP. Since this is kind of the overall mission anyway, it isn't adding anything to the budget.
Push the iOS bridge. Have people contacting creators of the top apps on other marketplaces, pointing them to the bridge. If it is an important app, maybe even offer money for the port. If the iOS bridge is as easy as it is supposed to be giving developers 10-20 thousand to spend a week on it might work out pretty well.
Dropping a mobile choice makes little to no sense. For one UWP is a great idea when you have lots of platforms. At this point though there is Windows 10 desktop and Xbox. Sure there are some little things in the works that may or may not succeed, like Windows 10 arm... but right now they're trying to get people to develop UWP apps, which is only two platforms, one of which is pretty locked away (Xbox) so not a lot of apps are really going to translate there. So ultimately UWP means Windows 10 desktop now. Why would anyone do that instead of just building with older, proven, faster apis? Lets give them a reason with bringing back mobile!
In summary:
- Management caused this problem not the platform.
- Take a small scale approach but reward fans for their loyalty.
- Give UWP a purpose.
- Push the iOS bridge to get developers to port apps to UWP.
- Play the long game with UWP mobile app build up.
