Apple.the name says it all well the ios is best of the platform one can have the privacy and the smoothness of work is just abkve the par exellence level the phone features 4.7 inch display which is the best size according to me as it fits our hand well the pixel density is well camera shots are reallyy great with 8mp front and 12mp rear the phone is quiete a bit heavier than the former version 6 the sound quality is best wifi lan strengh and range is vey good but yess its costly although for an apple geek prize doesnt matter
