I am using Resmi note 4 since 1 year.Seriously, I am very happy for it because there is no need to buy a new phone because of its performance are as like as when I brought it.Its battery backup is fantastic.If I would brought another phone instead of this than I would be at a great loss and I would be a follish.I am very happy with the overall performance.Mi brands are far better than samsung, vivo, oppo, etc.So go for it.This phone is long lasting and you will not face any kind of problem in this.
