I' ve been using this device for 1 month now. Here is a detailed description of my experience with Mi A2.
Camera
The back is a combination of 12+ 20MP Sony Cameras and as a result the phones performance very well. The camera works very well even in low light .
The selfie camera is a 20MP shooter and proves to be very promising when compared with other phones of same segment.
Battery
The battery is a 3070mAh battery and easily lasts a day with normal use but when heavy use is cosidered we need I had to charge it by evening. Frankly if you want a phone that lasts long hours, this isn' t the one.
Looks and feel
The Mi A2 is not anything like a premium phone but it feels really good in hand. The screen is 5.9 inch and is easy to hold with one hand. There is no notch but the phone still catches an eye.
Hardware and Software
Powered with Snapdragon 660 and 4 GB of RAM this phones has never lagged during the period I used. Games like PUBG and Asphalt ran smoothly.
The phone runs on Android Oreo and as an Android One phone it will surely upgrade to Android Pie by Dec.
