I would like to review this phone in sections as below:
camera; as the name of the phone this phone is the best selfie phone in this price range camera has some fantastic features improves selfie experience, I own this phone from 1 year, so I can say that this phone has better selfie camera than back camera
Zenphone selfie comes with variants of 16 and 32 gb with 2gb & 3gb ram
From 1 year since now I have not experienced any lag good for multi tasking.
Only one thing I do not like about Asus zenphone is the display, color reproduction is not as good as had considered.
