Hello friends my Name is Saurabh .
In my opinion as I am note 4 user it is good but not so much good so that I recomend it to someone.
I am telling it good as it has longer battery life, a high performance RAM as well as sufficient facilities were provided.
But still I am not reccomending it to anyone because it has:
Charging issues: the charging cable is so bad that it has a cut in the pin side without any external harm.Also the pin of charging is of bad quality so often stops charging even on slight touch to the port.
Camera is not so good as written.
Hangs many times.
Switch off and restarts sometimes.
5.And the main thing is ignorance that means the company doesnt provide updates to the model which become 1 yr old. As in case of xiaomi redmi note3.I have 3GB RAM varient but still sticked to marshmallow.The forum said that it will provide update by the end of november then daid in december but still no result. So that I think they will do this to Note 4 users also.6. Also it has some network issue with sim cards. Often the network becomes null and again comes back on restarting of doing on and off to the flight mode.So that my review on Redmi note 4 ( a budget phone , helpful as well as painfull.)
