I strongly suggest that if you are willing to buy a Xiaomi Redmi phone, then DO NOT go for Redmi Note 4.
1) The camera quality of this phone is just pathetic. The images are not 4k it comes slightly blurred most of the time, so taking photos is not really preferable on this phone.
2) Phone screen freezes and crashes WAY too much. So it becomes really annoying if you’re doing something important and all of a sudden the screen freezes, so you have to force reboot it.
3) This phone can only be used if you want to do day-to-day activities, such as WhatsApp, or calling. But most of the time, it is not able to run high end applications, as it starts crashing.
4) Many system apps crash a lot, such as themes, google photos, etc. It will keep dislaying- this app stopped working, and this also becomes very irritating.
5) Overall, the processor of this phone is quite slow and most of the time lags.
5) I’d say this phone is DEFINITELY not worth the money that is paid for it.
So, I recommend to not go for Redmi Note 4 as it is a very poor product of Xiaomi.
