I've been using it from past 2 weeks, so I'll be sharing you with the cons of Redmi 4A!
1) Though battery life is 3120 mAh it's great but not huge keep in mind! If you have misconception that it will last a day on have usage, sorry! I can play 50 games of clash royal ( 3 mins for a game) and battery will be dragged to 20-30%
2) It's a delicate device if you're a rough user a big NO from me to go and purchase this one!
3) 2gb ram and 16gb rom( internal memory) this might be sufficient to casual users but for heavy users it's again a drawback! Oh xiaomi.
4) Last but not the least! No finger print scanner and gorilla glass c'mmon can understand about finger scanner but why don't you people provide gorilla glass?
