I work at an Apple repair factory store and I am more knowledgeable about Apple products.
According to spy, the iphone 6s screen is the same size and process as the iPhone 6.
Similarly, the iPhone 5 and iPhone 5s, only the processor and other details are different, everything else is basically the same.
In terms of the process of changing the screen. iPhone 6s will continue the unibody screen that the iPhone family has always had.
That is to say, the replacement of the screen is also divided into whether to replace the internal or external screen.
Screen breakage is divided into situations.
1, the outer screen broken, touch function and display completely normal. This situation must meet the touch and display completely and fall before the same, without any abnormalities. In this case you can replace the outer screen alone, but the replacement of the outer screen requires professional equipment and technology, belonging to the factory level operation maintenance, requires a professional master manual and mechanical mold unity of operation. Here it involves experience, equipment good or bad, as well as the degree of care. You in the local after-sales or general direction of the repair point is no way to replace alone, will require you to replace the entire internal and external screen as a whole.
2, regardless of whether the outer screen is broken intact, if the inner screen display is not normal, or the touch function is abnormal, this situation must be the whole inner and outer screen integrated one replacement, is the whole of the above figure to be replaced.
