Anonymous, 01 Nov 2016Hi, I have changed it to US but still not showing update for windows 10First change region to US, then install windows insider. Log in to insider app,proceed. You will be notified when win 10 is available. But purchase a portable charger before updating. After update your phone will b having max 3-4 hrs back up.

Anonymous, 01 Nov 2016Hi, I have changed it to US but still not showing update for windows 10I don't know why you are not getting update notification!! But I am using win 10 now. Its better than 8.1 very user friendly. But battery is draining in just 2-3 hrs. I recommend don't update if you're using your phone for calling purpose too. Phone is heating too much after the update. So think before you proceed!!
without flashing Lumia with Chinese firmware you got Windows10 update?
Win 10 available for Lumia 638 officially..just change region to US. I am from India...I updated my phone to win 10 but the battery is draining so so fast...its draining from 100 to 0 in just 3 hrs...so think before you update.
