I used this phone in last 3 month. This is best mobile in this price with nice features.
There are sapperrate sound system and very clear and laud.
Only one issue I feel, the screen size is less than other mi phones.
It is also user friendly and comfortable in used, its also used for gaming and multitasking.
Bettery durability is best I have only charged this phone in 1 and 1 half hour and used all day easily.
A minor issue creat when I play high graphic game its heat too much in starting days but after some time its normal.
Cool and dashing look.
I said only one thing dont wast you money in oppo and vivo buy this phone and enjoy.
