Moving to 950 from 640 - What features would I be losing out on?

[ThermoDust]

I want to buy a 950 while it is on sale and was wondering what features I am going to lose by making the move from my 640 (w/Win 10).

I hear that it is missing double take to wake, what else is it missing? I cannot find a good list if someone can ramble some off that would be great. Thanks.

If you are in the US and buy a dual sim version, you lose Visual Voicemail. Other than that, I think the 950 is a great upgrade. I moved up from an 830, which is the same processor as the 640. Definite improvement!

FM radio is missing also, but still a good upgrade. I just went with the 950 from the 640 also.
