In case your screen of the iPhone 12 is cracked, does not respond to touch, or does not display an image when the phone is turned on, you can use this guide to replace the display yourself.

The combined speaker + headphone sensor assembly attached to the back of the display is paired with your individual iPhone at the factory, so you need to transfer it from the old display to the new one whenever you replace the display.  It contains a flood illuminator, which is part of the biometric security element Face ID.  If the Face ID is damaged or replaced, it will stop working, so be careful not to damage any of these components during this procedure.  In the event of damage, only Apple or an authorized Apple technician can restore Apple ID.

Note: True Tone is disabled after the screen is replaced, even when using the original Apple screen.  In addition, your iPhone may temporarily display a,, genuine" warning.

Step 1Removing the pen talobe screws

Before starting, it is necessary to discharge the iPhone below 25% because a charged Li-ion battery can ignite or explode if accidentally cut.

  • Turn off iPhone

  • Unscrew the two 6.75 mm long pentalob screwson the bottom edge of the iPhone using a Pentalobe screwdriver (Ph0001.2)

Opening iPhone will break its waterproof seal, so have a replacement seal ready before beginning this step.  Without a new seal, your iPhone will not be waterproof.

Step 2Opening 1

Warming the bottom edge of iPhone helps soften the screen protector and make it easier to open.

  • Using a hair dryer or heat gun, heat the bottom edge of iPhone for about 3 minutes to bring the temperature to about 80 ° C.

  • Do not put iPhone in the microwave !!!

Step 3Opening 2

  • Place the suction cups near the bottom edge of the iPhone, one at the front and the other at the back, and gently push it into place.

  • Hold your iPhone securely and use gentle suction cups to separate the screen from the back of the phone.

  • After separating the display approx. 3 mm from the back, insert the Fixservis card into the gap.

The glue that holds the display in place is very strong, so creating this initial gap requires considerable force.  If you have difficulty, reheat the bottom edge and gently slide the screen up and down repeatedly to weaken the glue until you create a gap to insert the Fixservis card.

Step 4Opening 3

  • After successfully releasing the adhesive from the edges, remove the suction cups.

  • Open iPhone by turning the display to the left like a book.

  • We recommend that you support the display so that you do not tear off the flat cable that holds the display from the system board.

For now, don't try to completely detach the display, as a few fragile flat cables still connect it to the iPhone's motherboard.

Step 5Removing the battery connector and display cover

  • Remove the two 1.1 mm long screwsusing a Pentalobe screwdriver (Y) securing the connector cover and remove at the same time.

Throughout the repair, follow each screw to make sure it returns exactly where it came from to avoid damaging your iPhone.

Step 6Disconnecting of the battery

  • Use the tip of the Spudger to disconnect the battery connector on the system board from the system board.

  • Bend the connector slightly away from the system board to prevent accidental contact with the outlet and power to the phone during repair.

Step 7Disconnect the OLED display + digitizer

  • Disconnect the OLED panel and digitizer cable connector using the Spudger.

Step 8Remove the front sensor connector cover

  • Using a Pentalobe screwdriver, remove the four screws that secure the front sensor connector cover:

- Three screws 1.1 mm long

- One 1.4 mm long screw

  • Then remove the cover.

Throughout the repair, follow each screw to make sure it returns exactly where it came from to avoid damaging your iPhone.

Step 9Disconnect the front sensor connector

  • Disconnect the front sensor assembly cable connector using the Spudger or nail.

Step 10Remove the display assembly

  • Remove the display assembly.

Step 11Removing the Speaker / Sensor Assembly

- Two 1.4 mm long Phillips screws

- One Y000 screw with a length of 1.7 mm

- One 1.2 mm long Y000 screw

Step 12Flip the speaker assembly over

  • The handset speaker is slightly stuck in place.

  • Use the Spudger to gently pry the top edge of the speaker.

  • Flip the speaker assembly down and out of the top edge of the display.

The speaker remains attached with a very thin flat cable.  Be careful not to strain or damage the cable.

Step 13Warm the top edge of the screen

  • Use a hair dryer or heat gun on the top front of the display for 1-2 minutes to soften the sensor mounting glue.

Step 14Ambient light sensor compartment

  • Use the Spudger to lift and separate the ambient light sensor from its notch on the front panel.

  • Then remove it with tweezers.

Be careful not to damage the light sensor ribbon cables when prying.

Step 15Install a new LCD display

  • Install the speaker + front sensor assembly on the new LCD display.

To reinstall, follow these instructions in reverse order.
