Their downfall happened the day they decided go all in on Windows Phone instead of Android.. And that was 100% Elop doing..

But i don't believe it was a grand plan from MS to screw Nokia so they could buy it..

Some even suspect that MS just bought Nokia because Windows phone was not selling and Nokia was loosing money, so MS was afraid Nokia would turn to Android and they would loose their flagship devices..

So they needed to ensure a phone maker for Windows Phone and wanted go into making their own phones, Nokia had a good brand that they had a good relationship with and Elop was still there to make things easy..

On the other hand, if Nokia had focused on Android from the start or at least had devices on both systems, they had the potential to be the leaders on Android phones by now..

Remember that nokia was already selling linux phones before it switched to windows.

It was a costly and useless move.
