I recently had the experience of using Redmi Note 3 and here is how it goes-
DISPLAY: The display of this phone is good, nothing extraordinary about that, does its job nicely. It does not have any Gorilla Glass so that a downside.
BUILD: The build quality of the phone is okayish, It didnt seem strong. The phone is very thin and looks good overall.
CAMERA: The camera quality is very good. This is the most impressive aspect of this phone. Images are good in all conditions.
FINGERPRINT SCANNER: The response time of fingerprint scanner is very less. It is a good feature of this device
SOFTWARE: The MiUI is nice in terms of looks and animations but there are a lot of bugs for example when I send sone files on this device via bluetooth, then it prompts me if I want to receive the file, when I click yes, nothing happens. So MiUI fails to do its job.
Overall I am not satisfied with the device and I wouldnt recommend it.
