Redmi 4a you can buy it online only
But many defective pieces are sold online
It has 3100mah battery life which is very less
Fully charged phone will be discharged in half day of usage
There are more phone with same features and long battery life
Rear camera is 13Mp which is one good feature of the phone
It has 3gb RAM which is adequate for this phone
But installing more application wil make phone hang
It is available in only three colour so no more option for color are available
System update also dont come early in this phone
Price is reasonable for this much feature
