I own a ASUS Zenfone 3 5.5" and just notified for system update.
1) Improved live streaming for Facebook
2) Improved Bluetooth connectivity when paring up with Garmin Smartwatch
3) Improved feature performance when double tap to wake up screen in Touch Gesture
4) Removed double tap to wake and sleep when Touch Gesture is off
5) Fixed Game Genie live stream ***malfaction*** issue while playing Pokemon Go.
Original wording by ASUS is wrong *** malfunction ***
I do not use all of the above features but still update anyway.
