Hi i have 640 dual sim, my region is germany, should i change my region to US?
Only if you are not worried about Cortana working. release notes say to set language, region, etc. back to default before updating or Cortana will break.
I couldn't install it on my Lumia 640XL, region in settings is USA, actual region is Ukraine.
