I recently bought redmi 4 after getting fully annoyed with samsung j2 ace. Really it have not the enough space that redmi provides with the same cost. Though the sound quality is okk but if you have to download more than 4 apps my god it will hang. Battery backup is worst. If your battery is at 30. It will not take more than 15 min to get dead. And if I tell you about redmi I saw full movie at 19 percent. Design is good but cannot be taken as the best one. And after looking redmi with same cost and more features it looks expensive with its limited features.
