I used zenfone 2 for 4 months by now.
Asus grossly neglected the basic function of a phone - call quality.
90% of the times, the voice breaks while in call. Either me or the person on the other side of the line wont be able to hear voice clearly.
Please dont buy Zenfone 2 if you want a phone with good voice clarity.
There are lot of pre-installed apps - both third party & Asus apps - which annoy most of the times using up battery and data.
The phone HEATS UP immediately after charging, video call, etc.
Call Quality - 1/10
Battery life - 5/10
Rear Camera - 5/10
Selfie Camera - 6/10
Gaming - 7/10
OS - 5/10
Rest of the features are good.
Consider Moto X Play instead of Zenfone 2.
U cannot return Asus phones on Flipkart. They will replace but not take back. Be careful if u r buying on Flipkart.
It is bad luck that every one reviewed this phone for all features except CALL QUALITY.
Buy this phone if u use it less for calls and more for other purposes!
Thank you.
