We are still working on software updates for the Honor 6X. Please be patient and continue following our social media channels: @USAHonor on Facebook and @Honor_USA on Twitter. Thank you. (NS)
Hauwei actually said when they announced the Honor 6X at CES 2017 that EMUI 5.0 + Android 7.0 Nougat would be rolling out to the Honor 6X Q2 2017. So the official deadline is sometime before the end of June.
