I downloaded the Upgrade Advisor and got to know that my Lumia 1320 is not eligible for Windows 10 update. I don't understand the kind of partiality we are coming across despite paying full amount and having genuine products! I don't think this has to do anything with operator or service provider.
All Lumia 1320 has to be same, then why no update for certain 1320s? This is a clear partiality.
