I am using samsung galaxy j7. It is a wonderful featured cellphone. I am happy with my phone. The best part of phone is its battery power which is used for longtime.This is a very good 4G phone.
However I would have liked a few features from my previous Galaxy S3 phone to be maintained. These are:
LED blinking on missed call / unread SMS
Autosignature in text message
LED light red while device charging etc.
