This phone does what it is expected to do. It gives you best specs for the price. Call quality is excellent and the phone is extremely light in weight. Design is sharp. I did experience a little hanging initially but I had almost all apps open at the same time.
The only limitations I could find were primary camera which is just about fine for the ocassional pic. The other one is ROM which is low. I could see that most if the apps could not be moved to SD card. I was using a Asus zenfone 6 earlier and thus getting used to a smaller screen. Because of this I did not even look at Asus Zenfone 2. If your budget allows, you might want to check that out.
