Its a very good choice on a small budget.i tell you why.
Camera-camera is good for day light shooting.
Screen-IPS screen with HD+ (7201440) Display, it looks very nice.easy to read in a daylight.
Note-mobile screen has round shape ( but screen shot has corners, IDK how)
Sound-sound quality is good, in speaker as well as in Earphone ( Earphone is not provided with handset) Phone speaker is loud enough to fill a room.
Battery-Battery is decent enough for a day use.
OS and UI
Comes with android version 8.1 Ui is great, Easy to understand.it comes with some unnecessary pre-loaded apps wich can be deleted ( but not the MI apps)
Network calling
I have used it in WhatsApp calling only and the voice clarity was good, no issue.
