Redmi 3s is mi product which is a launched recently and people are crazy about to buy it.Because it have good features n specification.Almost compatibility to redmi note 3.But note 3 having high feature and price and also launched just 2 months before of 3s.Same look and same colour launched.Differnce is only 3s is having low price and low gb ram and not containing finger print sensor.All accesibility is same by the way.But all people reviewing on this bad because it hang early and heating fast.Mi market slow down by this mobile.I think only some mi mobile are come better in the market which are much more useful for us which is redmi note 3.So people I recommended u not to buy such phone which are having low budget n low specification.small size are also not suits to anybody now.I think it not touch the market of redmi note 3 becz not better review from people.It also very difficult to buy a any mi recent phone online.Not easily available.
