I got my Asus Z6 Yesterday.
Out of the box It started to make many FOTA updates while I was setting other things.
In the end I got version
WW_16.1220.1908.189_0
The Audio part is really disappointing.
Notifications audio volume is low.
In Call volume is low. It's impossible to understand anything if not in a complete silent room.
On the other side I got some report that even my voice is not clear and loud.
Audio for videos and music is good in volume but it's not Sharp, Clear.
Really there should be some issues on audio part.
My previous Asus Z3 was far better in these aspects.
I really hope that everything will be resolved in next updates.
Please make Happy Again for choosing the Zenfone Series.
Thanks
