Hello frends, redmi 3s is a good smart phone that has maximum features required in a smart phone
It has long lige battery which allows you to enjoy its features for a long time specially whrn you are in a tour.
I baught this in a december 2016 as per the prize it gives a good feed back, if you care for this mobile then it do not hang or hangs ocassionaly.
The only disadvabtage it has the heating problem but it can be resolved by resetting the mobile
Another problem which I experience is the speaker problem.
Althaugh the product is good if you looking for a budget phonr then go for it.
