If you could design your own phone what features would it have and what would it look like

Just wondering because there isnt really the perfect phone for everybody so if you could design your own phone what materials and button layout would you use also what type of specs would you like it to have? Id personally use a soft touch back like the first gen n7 with buttons like the s4 active i would use retina display and have it be 5.0 inches... Id also have it have 2gb of ram with a good proccesor tomrun games with out any hiccups and have at least 15 hours of battery life
