My first mobile in lumia world I got fanstastic experince by this inspiration I next took lumia 535. the features about offline msps snd cortana is amazing. most of the persons around me they dont know how to use cortana. what they have to do when we restore lumia mobiles we must select language as uk eng bcoz indian language doesnt suppourt for cortana then select country and region as India.after lumia stars normally download language up to 60mb in my guess then select male or female version. cortana is better than siri. cortana suppourts offline commands such as alarm and calling and some other features. if they again release the 520 I definitely order one for me.
