PROCESSOR: The Mi A3 runs on a Snapdragon 665 processor. The one I have is a 6GB variant and comes with 128GB internal memory in the series. Considering the price of the mobile it is not very high and not the value for money. A lot of other smartphone manufacturers provide better features at this price.
DISPLAY: 6.08 inches(Super AMOLED) and an in-screen fingerprint sensor.
CAMERA: This device features a triple camera setup(48MP+ 8MP+ 2MP) it also has an LED flash. The main camera is of 48MP(Sony IMX586), which provides clear shots at day time and also at night. The camera setup also features an ultra-wide-angle camera of 8MP and a depth sensor of 2MP. The front camera is 32 MP which is awesome for selfies.
BATTERY: This device has a 4000mAh built-in non-removable battery. It also features 18W fast charging, in place of a traditional port it has a USB type C.
INBOX ACCESSORIES: 10W power brick, USB type C cable, and some paperwork.
On an overall basis, Mi is famous for its customised OS, they should have launched the same device with MIUI. The phone meets the expectations of a user but it could have been better in many ways.
