I bought this awrsome smartphone few days ago and till useing .xiaomi is a chines company .it established scince 2006.xiaomi made a briliant phone in 2016 name is xioami redimi note 4.the phone comes with 3gb and 4gb ram virsion.i think 4GB ram virsion is too good than 3GB ram virsion.
The phone very smoth working.played high resioulesion game, s no lags, no hanging and heating issues.the bettry backup is so nice .you used this phone 1day easely.it also give you 64 gb internal storage to lots of memories you save .
My opinion xiaomi is better than oppo smartphone.
You should recently buy xiaomi redmi note 4 4GB ram
