@CH_ASUS I've been using Zenfone 3 (still own it), used Zenfone 5z (for review), Zenfone Max Pro M2 (for review), and more. Rear fingerprint sensor placement is very comfortable and faster to both unlock & start using the device at once. Thus if it's the same with Zenfone 6 (team rear) it's cool, but I'd like to see something new, like side, placed.
New Zentalk is Classy.
