I'm die heart fan of windows phone specially 950xl device, but unfortunately Microsoft has decided to stop support this platform.
As Microsoft is going to drop support for window 10 mobile as off December 10, 2019, lots of applications will also drop a support for same specially whatsapp. So I recommend that Microsoft should officially release Android rom for lumia devices (mine is
950xl) so that at least windows users can migrate to android easily without purchasing new android device ("Reusing hardware").
Or is there any way to install android (may be unofficial support) on lumia 950xl so that I can migrate from windows to android after December 10, 2019.
