Xiaomi have been providing good phones for a long time. Redmi 4 is also one of them. But the special thing is that the Redmi 4 appears to fulfill all the requirements in a low price. There has not been a big change in the basic formula of Redmi series. Like the Redmi 3s , Redmi 3s prime. Redmi 4 comes with 5 inch screen. 13 mp rear + 5 mp front camera , 8.65 thick and 150 gm grams weight. You can easily use the phone with one hand. 13 mp rear camera makes the focus faster because of phase detection autofocus feature. Selfie from Redmi 4 is fine not so good and it takes time for selfile. 4100 mAh battery is also the good. acording to me Redmi 16 GB or 32 GB both variant for buy.
