How To Repair My Cracked Iphone 6 Screen

Introduction

Learn how to replace your iPhone 6s screen. This part comes with the front-facing camera, sensor assembly, and EMI shield already installed, making for an easier repair.

All you need to do is remove the old screen and transfer the home button to the new screen, in order for Touch ID (fingerprint scanning) to function.

Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

Power off your iPhone before beginning disassembly.
Remove the two 3.4 mm P2 Pentalobe screws on the bottom edge of the iPhone, next to the Lightning connector.

If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping over the glass. Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered. This will keep glass shards contained and provide structural integrity when prying and lifting the display.

Wear safety glasses to protect your eyes from any glass shaken free during the repair.
If the broken glass makes it difficult to get a suction cup to stick in the next few steps, try folding a strong piece of tape (such as duct tape) into a handle and lifting the display with that instead.

Optionally, apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.

Heat softens the adhesive securing the display, making it easier to open.

Opening the display on the 6s separates a thin strip of adhesive around the perimeter of the display. If you prefer to replace the adhesive, have a set of new adhesive strips ready before you continue. It's possible to complete the repair without replacing the adhesive, and you probably won't notice any difference in functionality.

Apply a suction cup to the lower left corner of the display assembly.
Take care not to place the suction cup over the home button.
If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices and is held down with adhesive.

Pulling too hard may damage the display assembly. Apply just enough pressure to create a small gap between the display assembly and the rear case.
If you have any trouble, heat the front of the iPhone using an iOpener, hair dryer, or heat gun until it's slightly too hot to touch. This will help soften the adhesive securing the edges of the display.

There is a notch on the underside of the display, just above the headphone jack. This is the safest place to begin prying the phone open. Place the flat edge of a spudger into the gap between the screen and rear case, directly above the headphone jack.

Use the suction cup to open the display, breaking the last of the adhesive. Don't open the display more than 90º, as it is still connected at the top by three cables that may break if stretched.

Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel as a hinge. Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone. Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.
