Android O Is Now Officially Android Oreo - Coming To Zenfone 3 & 4 Series !

ZenUI 4.0 and Android O for Zenfone 3 will come by 10 months from now...!!!!!!!!
This is simply not acceptable as other manufacturer's as very fast on this....secondly why so much time is required to provide ZenUI 4.0 and Nought 7.1 update to Zenfone 3....!! Can't understand ASUS.....
Next time I will double think to consider ASUS as my next phone....
