If you replace the screen with the original apple screen, it's not much different than it used to be, but if you assemble the screen cheaply, it's hard to compete with the original screen in terms of display and touch experience. The difference between the original iphone screen and the Assembly Screen 1, color: assembly color distortion easily, looks rustic. With the original obviously have a difference 2, precision, texture: the original screen surface similar to the steel film arc design, called table screen, table screen and screen close fit, very beautiful. The assembly can not be tight, beautiful, feeling very inferior. 3, Stability: assembly screen use up a lot of small problems, can not afford to fall, sometimes even if not fall will be their own fault. 4, inside difference: sometimes look at the surface is difficult to distinguish, open a look, the difference between heaven and earth.
