If there are no major surprises, Apple will present on March 21 at the event that they have a 9.7-inch iPad Pro and a 4-inch iPhone that we currently hope will be called iPhone SE. If the Chinese are famous for something (at least in the area where I live), it is for copying practically anything that exists and even anything that is talked about without being presented. This is the case of the iPhone SE, a device that has already "appeared" in Shenzhen, China.
Some stores in the Huaqiangbei market are selling what looks like an iPhone the size of the iPhone 5s with the design of the iPhone 6s. We cannot say that it is a very accurate copy, especially when we look at the bottom of the three devices together. The iPhone SE in the video has the holes in the Lightning and 3.5mm ports bigger and more profiled, something we don't see on the original iPhone. On the other hand the display glass does not seem rounded around the edges, which is known as 2.D Glass.
In China they already "have" the iPhone SE
The Chinese device also seems thicker than the iPhone 6s, but it seems the optical effect resulting from having a larger frame to disguise the absence of the aforementioned 2.5 Glass. Finally, if you look at the color, that of the Chinese iPhone SE seems darker than the iPhone 6s in the video.
On the other hand, in the video we do not see at any time what is there when this iPhone SE is turned on. Most likely, as usual, you will use an Android Launcher that has an image similar to iOS 9, but that will not offer the same performance at all. In any case, those who have one of these stores nearby can already buy a 4-inch iPhone with (almost) the design of an iPhone 6 / 6s.
