Am using this phone since 4 years and I realy love this phone because the phone they designed with metalic body realy awsome so this phone looks realy cool And the key features of iphone 5s is 4g supported and finger lock too Negative portion of this phone is battery backup.Battery backup of iphone 5s is very low.Dont compare iphone5s with new generation mobiles or any other new iphone series becuase iphone 5s was build in 2013.
