Updating ZS570KL International version
Product Model Name: ASUS ZenFone 3 Deluxe (ZS570KL)

Operation System / Firmware or BIOS version : Android 6.0.1 Settings>About>Software information: WW_126.96.36.1991_20170117
I have the international version of this phone. I get notifications of updates for the installed applications but nothing at all for the system (firmware and Android). The support I've been able to contact so far has told me that I have the latest firmware available for this particular CPU.
I thought the SKU ( first 2 letters of firmware like WW) was what really mattered.
But a later Android version is what I would really like.
