This is very big phone with large display. The sound has been increased in these models, previously iphone used to have only one speaker, but iphone 7 and 7 both have duel speakers. iphone 7 has two camaras at the back and the second cam is used to capture candid images in the phone. It is really good phone for gamers because of the size of the screen, huge storage space it has, and the graphic qualities it has! Battery backup is also very good. The only problem with the phone is it gets heated while playing games for long time! This is what I feel.
