Redmi note 4 is available only in online market.
you can buy from Fipkart, Amazon & Xiomi website.
but I suggest you do not go through xiomi redmi website.
when I was trying to buy from xiomi redmi website. after sometime I was getting out of stock popup.
the phone display view & look it too awesome
battery backup is too good I am not getting battery heating issues but when I playing game the mobile backside upper camera side is heating quitely.
fingerprint sensor is too responsive but u need to set first pin password for fingerprint access.
pin password for only security purpose when you restart mobile need to enter pin password first.
I f you forget pin password you have only one option is reset mobile phone.
Redmi provided one tool for reset password. u can use this for reset but your all data will be lost
overall mobile is too good as per price value.
