Introduction

For more advanced fixers, this guide will help you replace only the iPhone 8 LCD and digitizer assembly (a.k.a. the bare “front panel”). This requires you to transfer several components from your original screen to the new one before installing it—including the front-facing camera, earpiece speaker, LCD shield plate, and home button assembly.

For all screen/display repairs, it’s important to carefully transfer the original home/Touch ID sensor onto the new display in order for it to function. The solid-state home button is paired to its original logic board by Apple, so replacing it will render it unusable.

Note: If your iPhone’s auto brightness feature does not work properly after your screen repair, make sure your iPhone is updated to iOS 12. True Tone functionality is disabled after a screen replacement, even when using an original Apple screen.

What you need

Step 1

              Remove the pentalobe screws

Before you begin, discharge your iPhone 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 3.5 mm pentalobe screws on the bottom edge of the iPhone.
Opening the iPhone’s display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

Step 2

              Tape over the display

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.

Step 3

              Heat the display

Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
Use a hairdryer or prepare an iOpener and apply it to the lower edge of the phone for about 90 seconds in order to soften up the adhesive underneath.

Step 4

              Separate the display

Apply a suction cup to the lower half of the front panel, just above the home button.
Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.
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.

Step 5

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
Insert an opening pick into the gap.
The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you’re having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

Step 6

Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place.
Stop near the top left corner of the display.
Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

Step 7

Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate the adhesive.
Don’t insert the pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

Step 11

Open the iPhone by swinging the display up from the left side, like the back cover of a book.
Don’t try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone’s logic board.
Lean the display against something to keep it propped up while you’re working on the phone.

Step 12

              Disconnect the battery

Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:
Two 1.3 mm screws
Two 2.8 mm screws
Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.

Step 13

Use the point of a spudger to pry the battery connector out of its socket in the logic board.
Bend the battery connector cable slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

Step 20

              Disconnect the Touch ID sensor

Use an opening tool to pry under the left edge of the home button cable connector to disconnect it from its socket.
If the entire connector begins to flip up without separating, press down on the cable at the top edge of the connector with the flat end of your spudger, while simultaneously prying up the left edge of the connector. Be very careful not to damage the cable or connector, or you will permanently disable the sensor.

Step 21

              Remove the Touch ID sensor

Heating the area around the home/Touch ID sensor will help soften the adhesive holding its delicate cable in place, making it easier to remove safely.
Flip the display assembly over. Use a hairdryer or prepare an iOpener and apply it to the lower edge of the display for about 90 seconds in order to soften up the adhesive underneath.
Don’t overheat the display. It should be slightly too hot to touch comfortably.

Step 30

Use the point of a spudger to gently pry the proximity sensor out of its recess on the front panel.
Try to get your tool all the way under the sensor to pry it away from the clear plastic beneath. If you pry only against the cable, the sensor may separate from the cable assembly and will need replacement. If you’re replacing the sensor/cable assembly anyway, then it doesn’t matter.

Sarah Ybarra - Dec 4, 2018

So I’m pretty sure I know the answer to this - but can I test out the screen replacement without hooking up the camera, home button, etc? Can I just attach the three cables to the phone to make sure the screen works, or would it brick the phone?

Arthur Shi - Dec 4, 2018

Hi Sarah,

You can test the display without bricking your phone. It may boot-loop when the front sensor/camera assembly isn’t connected though. Be careful while you work with an opened phone with the battery connected…it is easy to accidentally short things out!

Jason Adams - Jan 20, 2019

After replacing the iPhone 8 LCD Screen and Digitizer, it seems that the battery is draining faster. I just wanted to see if this is a normal problem or was there something I missed during the install process?
