Problem with nokia lumia

I have nokia lumia 720 and i am facing some prolems. we can't send any video by blutooth or any other way.
even on whatsapp we can send any video from any phone but is this most advance phone we can't.
why?
2nd there is no fm, as i came to know that in next month we will get windows update. so will the upcoming update solve these common problems?
if not then i am going to buy android.

FM radio should be enabled with the upcoming amber update.
