Lumia 640 XL Windows 10 Release Date
I have a Lumia 640 XL with AT&T. I am wondering when Windows 10 mobile will be released on it. I have contacted Microsoft and they said it is up to the provider to release the update. I have the Upgrade Advisor app and it says "Good news! Yor phone is eligible for upgrade to Windows 10. We are working with your mobile operator and phone manufacturer to make the upgrade available for your phone and you'll see a notification when it's ready". I am wondering when Windows 10 Mobile will be released from AT&T for the Lumia 640 XL. Thank you.
