Windows 10 only for new flagship phone??

 

[charlatan1978]

Are you referring to the Lumia 950, 950XL and 550?
If so highly unlikely to be anything other than W10 mobile.

Windows 10 mobile will be available for some older Lumia phones.
What phone do you have?

But new features are not available for old lumia phone

Of course, features like Windows Hello will not come to all devices, or for that matter the biometric login or continuum. Expecting those features from a sub 200-300 dollar device without the necessary sensors in place would be a stretch.

What's going to come to all the phones including the oldies of the Lumia series is the subtler features, the little things that are making this ecosystem complete. The OS itself is coming to you. If you are on a two year old phone like a 520, 620, 720, I think that's something to be thankful about. Not all manufacturers give such shiny new things to old people.
