Guide overview

Before you begin

Follow the steps in this guide to remove or transfer the earpiece speaker and front sensor assembly in your iPhone 12 Pro Max. This assembly is affixed to the back of the display and also includes a microphone, ambient light sensor, flood illuminator, and proximity sensor. This assembly 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. The flood illuminator forms part of the biometric Face ID security feature, and Face ID functions will fail if the original component is damaged or incorrectly installed. Replacing it with a new part will also cause Face ID to fail, 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.

  • 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 6.7 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.
Step 2

  • If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.
  • Measure 3 mm from the tip and mark the opening pick with a permanent marker.
  • You can also mark the other corners of the pick with different measurements.
  • Alternatively, tape a coin to a pick 3 mm from the tip.

  • 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 clear packing tape over the iPhone's screen until the whole face is covered.
  • Wear safety glasses to protect your eyes from any glass shaken free during the repair.
  • If you can't get the suction cup to stick in the next few steps, fold a strong piece of tape (such as duct tape) into a handle and lift the screen with that instead.
  • If all else fails, you can superglue the suction cup to the screen.

  • To avoid damaging your screen in the next steps, note the following:
  • There's a plastic bezel on the underside of the screen. Your opening pick will go underneath this bezel.
  • There's a seam between the plastic bezel and the display panel. Don't insert your pick here or you'll damage the screen.
  • Sometimes the display panel separates from the bezel before you even get a chance to insert a pick. This may be unavoidable depending on the condition of the adhesive. In this case, you’ll most likely need to replace your entire screen.

  • The next three steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down three steps for an alternate method.
  • For complete instructions on how to use the Anti-Clamp, check out this guide.
  • Pull the blue handle backwards to unlock the Anti-Clamp's arms.
  • Slide the arms over either the left or right edge of your iPhone.
  • Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.
  • Squeeze the cups together to apply suction to the desired area.
  • If you find that the surface of your iPhone is too slippery for the Anti-Clamp to hold onto, you can use tape to create a grippier surface.

  • Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.
  • Use a hair dryer to heat along the bottom edge of the iPhone. The screen should feel slightly too hot to touch.
  • For complete instructions on how to use a hair dryer, check out this guide.
  • Wait one minute to give the adhesive a chance to release and present an opening gap.
  • Insert an opening pick under the screen's plastic bezel when the Anti-Clamp creates a large enough gap.
  • If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle a quarter turn.
  • Don't crank more than a quarter turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.
  • Skip the next three steps.

  • Use a hair dryer or heat gun to heat the bottom half of the screen until it’s slightly too hot to touch. This softens the adhesive securing it.
  • Improper use of a heat gun can destroy the display and/or battery—review this guide for instructions. To prevent screen damage, keep your heat source moving rather than focused on one spot.
  • For tips on using a hair dryer to soften adhesive, check out this guide.

  • Rotate your iPhone so the right edge faces you.
  • 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.
