The iPhone SE is a smartphone designed and marketed by Apple Inc. as part of the iPhone series of devices. It was unveiled on March 21, 2016, at Apple's Cupertino headquarters, and was released on March 31, 2016. Despite chronologically succeeding the iPhone 6 family's launch, The iPhone SE serves as a successor of the iPhone 5S. It maintains the 4-inch screen size and largely identical design to the 5S, but includes selected hardware upgrades from the larger iPhone 6S model, including its updated processor, rear camera, and support for iOS 10 software features, such as Apple Pay, always-on Siri activation, and Live Photos. It also featured a new colour in Rose Gold along with the standard Space Grey, Silver and Gold. The model was re-released with new storage options on March 24, 2017
