Hi Teddy
Asus will continuously provide applicable updates to our products for 18 months from the device first become available on the market. For any devices launched over 18 months, there will no longer be any system updates and maintenance (including ZenUI Launcher).
Sorry for any inconvenience this may cause. Thank you for your understanding and support.

When will Asus OFFICIALY Release The Pie Update (Not Beta Pie). Im waiting for it for like 5 Months already, please Asus Make it Quick.

Peace Out

Zenfone 4 Max Pro(ZC554KL) Pie Update
