Introduction

If your iPhone 12 screen is cracked, not responding to touch, or not showing a picture when your phone is powered on, use this guide to restore your iPhone to working order with a new screen, a.k.a. display assembly.

The combined earpiece speaker + sensor assembly affixed to the back of the display is paired to your individual iPhone from the factory, so you must transfer it from your old display to your new one during any display replacement. It contains the flood illuminator, which is part of the biometric Face ID security feature. If it is damaged or replaced, Face ID will cease to function, so take extra care not to damage any of these components during this procedure. If damaged, only Apple or an Apple-authorized technician can restore Face ID function.

Note: True Tone functionality is disabled after a screen replacement, even when using an original Apple screen.

  1. iPhone 12 Screen Replacement, Remove the pentalobe screws: step 1, image 1 of 1
    • Caution: 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 6.75 mm long pentalobe P2 screws at 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.

  2. iPhone 12 Screen Replacement, Tape over any cracks: step 2, image 1 of 3 iPhone 12 Screen Replacement, Tape over any cracks: step 2, image 2 of 3 iPhone 12 Screen Replacement, Tape over any cracks: step 2, image 3 of 3
    • If your iPhone has a cracked screen, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.

    • Lay overlapping strips of 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.

  3. iPhone 12 Screen Replacement, Heat the lower edge of the iPhone: step 3, image 1 of 1
    • Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

  4. iPhone 12 Screen Replacement, Apply suction cup(s): step 4, image 1 of 2 iPhone 12 Screen Replacement, Apply suction cup(s): step 4, image 2 of 2
    • The next two steps demonstrate the iSclack, a handy tool that we recommend for anyone doing frequent repairs. If you aren't using the iSclack, skip down two steps for an alternate method.

    • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger iPhones like the iPhone 12.

    • Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.

    • Press both suction cups firmly into place.

    • If your display or back glass is badly cracked, covering it with a layer of clear packing tape may help the suction cups adhere. The iSclack also includes two pieces of tape for this purpose.

  5. iPhone 12 Screen Replacement, Lift the display slightly: step 5, image 1 of 3 iPhone 12 Screen Replacement, Lift the display slightly: step 5, image 2 of 3 iPhone 12 Screen Replacement, Lift the display slightly: step 5, image 3 of 3
    • Hold onto your iPhone securely and close the handle of the iSclack to slightly separate the screen from the rear case of the phone.

    • Don't try to completely separate the screen; a small opening along the bottom edge is all you need.

    • Insert an opening pick into the gap under the display on the lower edge of the iPhone.

    • Skip the next two steps.

  6. iPhone 12 Screen Replacement, Apply a suction cup: step 6, image 1 of 2 iPhone 12 Screen Replacement, Apply a suction cup: step 6, image 2 of 2
    • If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the very edge of the 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.

  7. iPhone 12 Screen Replacement, Lift the display slightly: step 7, image 1 of 3 iPhone 12 Screen Replacement, Lift the display slightly: step 7, image 2 of 3 iPhone 12 Screen Replacement, Lift the display slightly: step 7, image 3 of 3
    • 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.

  8. iPhone 12 Screen Replacement, Separate the screen adhesive: step 8, image 1 of 3 iPhone 12 Screen Replacement, Separate the screen adhesive: step 8, image 2 of 3 iPhone 12 Screen Replacement, Separate the screen adhesive: step 8, image 3 of 3
    • Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the display in place.

    • 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.

  9. iPhone 12 Screen Replacement: step 9, image 1 of 3 iPhone 12 Screen Replacement: step 9, image 2 of 3 iPhone 12 Screen Replacement: step 9, image 3 of 3
    • Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.

    • Don't insert the opening pick too far into the iPhone, or you may cause damage to internal components.

  10. iPhone 12 Screen Replacement: step 10, image 1 of 3 iPhone 12 Screen Replacement: step 10, image 2 of 3 iPhone 12 Screen Replacement: step 10, image 3 of 3
    • The top edge of the display is secured with both glue and clips.

    • Insert your pick into the right edge of the phone. Slide it around the top-right corner and across the top edge.

    • Again, don't insert the pick more than a few millimeters—about the width of the display bezel—or you may damage the front panel sensor array.

  11. iPhone 12 Screen Replacement, Open the iPhone: step 11, image 1 of 3 iPhone 12 Screen Replacement, Open the iPhone: step 11, image 2 of 3 iPhone 12 Screen Replacement, Open the iPhone: step 11, image 3 of 3
    • If you haven't removed your suction handle or iSclack, remove it now.

    • Open the iPhone by swinging the display up from the right side, like the front 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.

    • During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

    • Remove two 1.1 mm long Y000 screws securing the battery and display connector cover.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

    • During reassembly, this is a good point to power on your iPhone and test all functions before you seal the display in place. Be sure to power your iPhone back down completely before you continue working.

  12. iPhone 12 Screen Replacement, Remove the battery and display connector cover: step 13, image 1 of 1
    • Remove the cover.

  13. iPhone 12 Screen Replacement, Disconnect the battery: step 14, image 1 of 2 iPhone 12 Screen Replacement, Disconnect the battery: step 14, image 2 of 2
    • Use a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.

    • Try not to damage the black silicone seal surrounding this and other board connections. These seals provide extra protection against water and dust intrusion.

    • Bend the connector 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.

  14. iPhone 12 Screen Replacement, Disconnect the display cable: step 15, image 1 of 2 iPhone 12 Screen Replacement, Disconnect the display cable: step 15, image 2 of 2
    • Use a spudger or a fingernail to disconnect the display cable connector.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

  15. iPhone 12 Screen Replacement, Disconnect the digitizer cable: step 16, image 1 of 2 iPhone 12 Screen Replacement, Disconnect the digitizer cable: step 16, image 2 of 2
    • Use a spudger or a fingernail to disconnect the digitizer cable connector.

    • If any part of your screen doesn't respond to touch after your repair, disconnect the battery and then re-seat this connector, making sure it clicks fully into place and that there's no dust or other obstruction in the socket.

  16. iPhone 12 Screen Replacement, Unscrew the front sensor connector cover: step 17, image 1 of 1
    • Use a Y000 driver to remove four screws securing the front sensor connector cover.

    • Three 1.1 mm long screws

    • One 1.4 mm long screw

  17. iPhone 12 Screen Replacement, Remove the front sensor connector cover: step 18, image 1 of 3 iPhone 12 Screen Replacement, Remove the front sensor connector cover: step 18, image 2 of 3 iPhone 12 Screen Replacement, Remove the front sensor connector cover: step 18, image 3 of 3
    • Swing the cover up from the left until the small clip on the right unhooks.

    • Remove the cover.

    • During reassembly, insert the clip on the right edge into its slot first, then hinge the rest of the cover into place.

  18. iPhone 12 Screen Replacement, Disconnect the front sensors: step 19, image 1 of 2 iPhone 12 Screen Replacement, Disconnect the front sensors: step 19, image 2 of 2
    • Use a spudger or a fingernail to disconnect the front sensor assembly cable connector.

  19. iPhone 12 Screen Replacement, Remove the display assembly: step 20, image 1 of 1
  20. iPhone 12 Screen Replacement, Unscrew the speaker/sensor assembly: step 21, image 1 of 1
    • Remove the four screws securing the speaker/sensor assembly to the back of the display.

    • Two 1.4 mm long Phillips screws

    • One 1.7 mm long shouldered Y000 screw

    • One 1.2 mm long Y000 screw

  21. iPhone 12 Screen Replacement, Flip the speaker assembly over: step 22, image 1 of 2 iPhone 12 Screen Replacement, Flip the speaker assembly over: step 22, image 2 of 2
    • The earpiece speaker is lightly adhered in place.

    • Use the point of a spudger to gently pry up the top edge of the speaker.

    • Flip the speaker assembly over—down and away from the top edge of the display.

    • The speaker remains attached via a very thin ribbon cable. Be careful not to strain or damage the cable.

  22. iPhone 12 Screen Replacement, Heat the top edge of the display: step 23, image 1 of 1
    • Use a hair dryer or heat gun or prepare an iOpener and apply it to the top front of the display for 1-2 minutes, in order to soften the adhesive securing the sensors.

  23. iPhone 12 Screen Replacement, Separate the ambient light sensor: step 24, image 1 of 3 iPhone 12 Screen Replacement, Separate the ambient light sensor: step 24, image 2 of 3 iPhone 12 Screen Replacement, Separate the ambient light sensor: step 24, image 3 of 3
    • Use the point of a spudger to lift and separate the ambient light sensor from its notch in the front panel.

    • Take care not to damage the light sensor ribbon cables while prying.

    • Continue sliding the spudger underneath the ambient light sensor and its cable to separate the adhesive securing the cable.

  24. iPhone 12 Screen Replacement, Pry up the microphone: step 25, image 1 of 3 iPhone 12 Screen Replacement, Pry up the microphone: step 25, image 2 of 3 iPhone 12 Screen Replacement, Pry up the microphone: step 25, image 3 of 3

    • Remove the earpiece speaker and front sensor assembly.

    • During reassembly, check the position of the black plastic module containing these components:

    • Proximity sensor

    • Flood illuminator

    • The module must be positioned so that these components are not obstructed by any adhesive.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

i am trying to source a replacement screen for my iPhone 12 that needs a new digitizer and battery. My main concern is since I cannot purchase an original part from apple and have to resort to eBay they have several option;

Lcd / Oled soft / Oled hard / Incell lcd??

I asssumed the 12 came with the oled screen and I’m worried that if I put a non original type screen it could damage phone after awhile?

what digitizer should I get?

Hi, I would recommend looking at places like Fixez.com rather than Ebay. Their prices are lower and they have a LCD buyback program which is very helpful. They have a wide ranging variety of LCD's. On a scale of best to worst LCD's its ranges: OLED Soft,OLED Hard, Incell LCD, LCD. I hope this helps

Hi there,

I have read that by installing an aftermarket screen, I would get a non-genuine display message. Has Apple addressed this issue?

Alex Hsu - Reply

Genuine components have chips that allow the phone to identify them - third party ones frequently do not. The phone is doing what it is designed to do so there isn’t really anything for Apple to address. Much as anything it’s to stop companies refurbishing iPhone’s ‘in-house’ and selling them as having genuine parts. The non genuine part message is t inherently a bad thing, it’s an advisory rather than an error.
