Today Asus has started sending out an update to Android 8.1 Oreo to the Zenfone 3 Max ZC553KL. This particular model launched in November of 2016, so it's good to see that the Taiwanese company hasn't forgotten about it, software-wise. The Zenfone 3 Max initially ran Android 6.0.1 Marshmallow, then got updated to Nougat, and now it's time for it to jump straight to 8.1.
It might in fact be the first Asus smartphone to receive this specific version of the OS. Other members of the Zenfone 3 line have gotten 8.0.
The new version is 15.0200.1807.406. Aside from packing all the goodies that Google's built into Oreo, you will also get Asus' latest coat of paint on top of that - a.k.a. ZenUI 5.0. It should take around a week for the over-the-air rollout to reach every single Zenfone 3 Max ZC553KL device out there, so don't panic if you haven't seen the notification just yet.
They weren't this clever before! Back then they only used to release like 4 to 5 devices at max every year, each of which are from different lineups starting from super budget to super high end, and all of them are probably one of the best, if not ...
and they released a lot more phones, versions last time, so don't count with better support! That is simple impossible, to care up to date so many phones. and google publish buggy versions or fixes as well :((
Asus > xiaomi. Android update is better than ui update
