Easy...
* Scrap the Lumia 650 and all support for Windows 8 phones
* Stop calling the phones by the name "Lumia"
* Sell only two phones: the MS 950 and the MS 950XL
* Put a metal back on the MS 950 and MS 950XL
* Take the silly Microsoft lettering off the front... but keep the windows logo on the back
* Include an active pen for free (which can lock into place inside the phone)
* Cut the price in 1/2
* Spend some of the 9 billion in cash reserves on the MS App Store in the following ways, all under the Microsoft brand:
. Resurrect MS Money as a UWP app to rival Intuit's Mint (who pulled their UWP app from the store in 2015). Without a personal finance app to connect to our accounts (en lieu of Mint, major bank, credit card, and utility company apps) their platform is not attractive to their bread and butter demographic (30 to 60 year olds)
. Build a generic Boarding Pass app which partners with the big airlines (United, Southwest, Delta, American, Alaska, Hawaiin, Jet Blue)
. Resurrect Groove, complete with a family plan of $9.99 (5$ cheaper than Spotify and Pandora)
. Add audio messaging/walkie talkie functionality to Skype (to be a serious competitor to Voxer)
. Create a unit on their Xbox team that creates MS original family friendly/mobile friendly games like Zoo Tycoon
. Integrate full parental controls on Edge mobile, Groove mobile, xBox mobile, and the OS, and work with AT&T to discount MS 950 phones when purchased for an entire family. Market the phones as the family friendly option in a complicated online world.
* Offer a $250,000 interest free loan programs to qualifying start-ups who will bring their app to the MS store (a MS shark tank)
* And finally, market the shorts off the device during every major primetime sporting event and special event (Oscars, Grammys, Emmys)
Keep doing this until they come out with the ultimate mobile device... the Surface phone!
