Perfect product!
used for 2 day here is honest review
look is awesome far better than redmi note 3
after first boot battery last for 5 hours from 50% then we got miui update that fixes ram optimisation
and battery after battery backup was exellent
optimisation increse and we get around 2gb ram free out of 3gb
ui is exllent than redmi note 3 there font change option added
even if camera is 13 mp but camera clearity better than 16mp redmi note 3
now processor u dont believe games runs smooth on redmi note 4 like asphal extreme
and redmi note 3 has some lags
mic quality is decent
speaker is like dolby atmos
figerprint unlocks within microseconds
volte supports
