I am using Redmi Note 4 from last 6 months and here are some problems i’ve identified.
–Cons
Below Average camera
Very low outgoing volume so other person can’t hear my voice
Phone brightness is very low
Touch doesn’t work while charging period
–Pros
Full HD display
4 GB RAM
Super fast processsor
VERDICT– after spending money around 15K I feel bit cheated and if anyone is looking this for long term use then i’ll definitely not consider this.
