I have used iPhone 6s. 80% I bought this phone by It’s body design and look. Ios9 operating system is used in this and apple 9 core is used. The performance of phone is very nice and easy to operate. ITunes is very helpful to music lovers. The led capacitiev touch screen, 12mp dual led flash camera and other features mad this phone awesome. Sound is low but Good to hear. Style and design is very good. And it’s worth for its cost.simple amazing phone with awesome features.
