iPhone: Glass separates from the display - what to do?

If the glass on the iPhone comes off the display, you should change the whole unit.

iPhone glass and display - one unit

If the glass has become detached from the display, for example, the only thing left to do is to replace the entire display.

• If the display and touch input still work, even though the glass has come off the frame a bit, this is more of a blemish. If you don't mind if the glass protrudes a few millimeters on one side, you don't necessarily have to replace the display.
• If the touch input is disturbed by the detached glass, you have to replace the entire display. This can either be done by a cell phone workshop for you, or with a little skill you can save costs and repair the iPhone yourself.
• Individual glasses are also sometimes offered on the Internet. As of iPhone 5, you can safely forget these offers. The retina display and the glass are fully glued under the factory under sterile conditions. It is therefore not possible to separate the two components.

So that you are on the safe side, we have summarized what you should pay attention to when buying a display for the iPhone 4.
