firasswat82Because Zenfone 7/7pro already had Zenui 7 with Android 10 and asus decided to build Android 11 on top of Zenui 7. Also you know that there is not much huge diffrence between Android 10 &. Android 11 officially from google and so that is reason there is not much huge changes to be noticed. Also let me tell you Zenfone 7/7pro will get a renewed UI with Zenui 8 which will be build on top of Android 12 in future for Zenfone 7/7pro.
I updated my phone to Android 11, but why was the phone manager, contacts, clock, file manager, weather, and other programs not renewed !!!! Because all programs are the same as Android 10
update android 11
