Step-by-Step Guide For iPhone 15 Pro Back Glass And Screen Replacement

October 10, 2024

Welcome back to Screen Fixed. Today we are going to teach you how you can replace the back glass and screen of the iPhone 15 Pro. When the screen or the back glass is broken or cracked you need to change them. This is a step-by-step guide that can be used for anyone “back glass or screen replacement of iPhone 15 Pro” according to your need.

However when you are replacing the screen or back glass on your iPhone 15 Pro please keep in mind that Apple’s parts pairing can cause some features to stop working. On iOS 17.6 and earlier, True Tone and auto-brightness will not work after a screen replacement even if you are using a genuine Apple screen. However with iOS 18 and newer you can restore these features by calibrating the new screen through Apple’s Repair Assistant.

Important Tools For iPhone 15 Pro Screen and Back Glass Replacement

Before starting your iPhone 15 Pro rear glass and screen replacement it is important to have all the tools and parts ready. This will make the process easier and more organized. Below is a list of everything you will need.

* iPhone 15 Pro replacement parts (iPhone 15 Pro screen/rear glass).
* P2 Pentalobe screwdriver.
* Heat gun or hair dryer.
* Tri-point Y000 screwdriver.
* Suction cup tool.
* Plastic opening picks.
* Spudger tool.
* Isopropyl alcohol (90% or higher).
* Microfiber or lint-free cloth.
* Tweezers.
* Replacement adhesive for iPhone 15 Pro rear glass.
* Replacement adhesive for iPhone 15 Pro screen.

Make sure to keep these tools close by. We also recommend choosing a quiet and clean workspace to make the process smoother. Having an electrical socket nearby is helpful too especially when you need to use the heat gun or hair dryer.

Step #1. Prepare the iPhone 15 Pro for Disassembling

* Firstly we need to get our device ready for disassembling.
* Please remove all the cables and wires from the iPhone 15 Pro when you are going to start the disassembling of the phone.
* Also check the charging status. It should be under 25%. A more charged battery is more susceptible to catching fire if accidentally gets damaged by the metal tool.

Step #2. Switch Off the iPhone 15 Pro

* Now we need to turn off the iPhone 15 Pro before attempting any disassembly.
* To do this you need to press the power button and the volume down button at the same time.
* Wait for a while pressing the button until you see the power off options on your screen.
* Now leave the button and slide the “Power Off” slider on the screen.
* After a few seconds the screen will go dark. It means the phone is completely off now.

Apply Packing Tape on the Back Glass and the Screen

* This is an extra step you have to follow if your phone’s rear glass or screen is cracked or damaged.
* Apply straps of the packing tape on the rear glass and cover it fully.
* This action will protect your eyes and face from the shaded small pieces of glass that could come out when pulling with the suction tool.
* Whether it is the screen or the back glass you need to make sure that there should be a smooth section on the bottom edge to apply a suction tool.

Step #3. Open Pentalobe Screws and Remove Them

* It’s time to open the pentalobe screws that are located on both sides of the charging port.
* The iPhone 15 Pro has two 7 mm long screws. You can use a P2 Pentalobe Screwdriver for opening these two screws.
* Take the screws out and put them on a secure place for reusing when reassembling.

Step #4. Apply Heat at the Bottom Edge of the iPhone 15 Pro

* Firstly we will apply the heat on the bottom edge of the iPhone 15 Pro. Because this area is safe for inserting 3 mm deel opening picks. Otherwise the remaining edges have cables and spring contact beneath the back glass.
* Use a heat gun or a hair dryer for heat application. Do this action for 20 to 30 seconds long. Excessive heat can damage the battery or the screen.
* It would be better if you keep checking your phone while applying heat and feel the warmth with your hands until it gets too hot to touch.

Step #5. Apply the Suction Handle and Insertion of the Opening Pick

* After heating the bottom edge we will apply the suction handle at the center of the bottom edge.
* Apply steady force to pull up the rear glass and create a line gap.
* Insert the first opening pick into the gap between the rear glass and the frame.
* Then remove the suction handle after opening the pick insertion.
* Please remember you can only insert the pick 5 mm deep at the bottom side between the rear glass and the frame.

Mark Your Opening Pick

* You can follow our idea for avoiding tar insertion of the pick inside the rear glass.
* You can mark your opening pick at the 3 mm measurements.
* Do the measurements with a scale and mark it with a permanent marker.
* Also you can stick a coin from the 3 mm measurements.
* This will stop the pick from deep insertion.

Step #6. Move the Opening Pick to Cut The Adhesive

* Now slide the opening pick back and forth to separate the adhesive between the back glass and the frame.
* Take the pick toward the bottom right corner of the iPhone 15 Pro.
* Here it’s better to leave the pick. It will prevent the adhesive from sticking again.

Information About the Between the Rear Glass and The Frame from the Right Edges

Before moving towards the right edges of the iPhone 15 Pro you need to know some important information about inside the glass

* The rear glass has a built-in charging coil and NFC pasted on the glass. The wireless charging cables are connected to the logic board near the volume button. So we can not insert the pick near the volume buttons for the safety of the cables.

Step #7. Apply Heat on the Right Edge of the Rear Glass and Slide the Opening Pick

* Use the hair dryer or the heat gun ( preferably use a heat gun) to warm up the adhesive between the rear glass and the frame. Heat will melt the adhesive and you can separate the rear glass quickly.
* Apply heat only for 20 to 30 seconds and keep checking the glass by touching your hand until it gets too hot to touch.
* Heating for a long time can damage the battery and internal components.
* Now slide the opening pick from the bottom right corner to the right edge of the phone.
* Keep sliding the pick until you feel the clip. The pick will feel hard to move.
* To release the clip you need to twist and turn the pick and also rotate the pick so that the flat side goes in. After some effort the clip will release the frame and you will be able to move the pick ahead.
* Take the pick toward the volume down button and leave the opening pick here.

Step #8. Give Heat to the Left and Top Edge of the Phone and Cut the Adhesive

* Now apply the heat on the remaining edges of the phone.
* Use the same heating equipment that you chose for the above heating steps.
* Insert the opening pick from the bottom edge of the phone and move it toward the left edge. You will move cutting through the bottom left corner’s adhesive and then cut the adhesive from the left edges.
* Here you will also find a clip that secures the back glass to the frame.
* Twist and turn the pick to release the clip and move ahead.
* Take the opening pick to the top left corner. Slide the pick carefully along the top left corner.
* Here is the top clip you have to release.
* If to stuck please use a flat-tip spudger to release the clip from the frame.
* Move the opening pick ahead and again you will encounter a clip on the top edge of the phone.
* Release it and move toward the top right corner.
* Rotate the pick along the right corner of the back glass.
* Slide the pick until you reach the volume up button.
* Leave the opening here. (Two opening picks are interested in the right edge. One is near the volume down button and another one is near the volume up button.)

Step #9. Swing Opening The Back Glass

* Carefully lift the back glass from the right side of your iPhone 15 Pro.
* If you feel any resistance check the edges again for any leftover adhesive or clips that may still be holding it.
* Once the back glass is loose rest it against a small box or something similar to avoid pulling or damaging the cable.
* As you know the rear glass is still attached because the cables are connected.

Step #10. Open the Screw of the Wireless Charging Connector Cover and Remove It

* The wireless charging cable is hidden under the connector cover.
* To open its 1.0 mm long screw you need a tri-point Y000 screwdriver.
* Open the screw and keep it safely aside.
* Please carefully secure all the screws so that you don’t have to face difficulty while reassembling. Also keep in mind that all the screws need to go back the same whole where they come from.
* Now use a tweezer for sliding the cover and unlatching it from the logic board.
* Remove the connector cover.

Step #11. Disconnect the Wireless Charging Cable and Remove the Rear Glass

* Pry up the wireless charging press cable using a flat-tip spudger or the opening pick.
* Disconnect the press cable
* Now the back glass is free and you can easily remove it completely.

Here the back glass has been removed. If you are only replacing the back glass of the iPhone 15 Pro then you can move to reassembling steps of the iPhone 15 Pro back glass.

The further steps will teach how to separate the screen of the iPhone 15 Pro from the replacement.

Step #12. Heat the Bottom Edge of the Screen to Separate The adhesive

* After removing the back glass, flip the phone facing the screen up.
* For Separating the screen we need to apply heat on the bottom edge first to melt the adhesive between the screen and the frame.
* Using a heat gun or hair dryer, apply heat for a while and keep checking the warmth with your hand.
* Don’t apply excessive heat as it can damage the battery’s internal components.

Step #13. Apply Suction Handle on the Bottom Edge of the Screen

* We will apply the suction handle on the screen.
* Please make sure the suction handle should be applied at the center of the bottom edge of the screen.
* Pull the suction handle with steady force until you see a line gap between the screen and the frame.
* Insert the opening pick into the gap and remove the suction handle from the screen.
Don’t insert the pick more than 3 mm deep into the screen. (Please see the screen information.)

Screen Information

When you are cutting through the adhesive holding the screen you have to watch out for a couple of sensitive spots.

* There are two cables that connect the screen to the iPhone 15 Pro logic board. One is just above the action button and the other is closer to the middle on the left side.
* Also there are tiny spring contacts around the edges of the phone. Be really careful not to push your tool too far here. If you go too deep you could bend or damage those contacts.
* Just take your time and stick to the right depth to keep everything safe.

Step #14. Slide the Opening Pick

* Now slide the pick back and forth to cut the adhesive inside the screen.
* Take the pick toward the bottom right corner of the screen and leave the opening pick here.
* The inserted pick will prevent the adhesive from resealing between the screen and the frame.

Step #15. Give Heat to the Right, Top, and Left Edges of the Screen

* Use the heat gun or a hair dryer for heat application on the remaining sides of the screen.
* Spend 20 to 30 seconds on every edge applying heat.
* When you are done with the heat application you can go ahead with the same opening pick.
* Move the pick along the bottom right corner and take it on the right side of the phone.
* Don’t insert the pick more than 5 mm long on the right side of the screen.
* Keep sliding the pick until you feel a hard stop.
* It is the clip that is securing the screen with the frame.
* To release the clip rotate the pick as the flat side of the opening pick goes inside. Then twist and turn the pick and apply some force until you feel and hear the clip-releasing sound.
* Now move ahead toward the volume down button. And leave the opening pick below the volume down button. As you know you can not go across the volume buttons cutting through the adhesive.

Step #16. Insert the Second Opening Pick

* Now we need to insert the second opening pick just from the first one.
* Move the pick quickly along the right edge to the bottom right corners and go to the bottom edge of the phone
* Slide the pick along the bottom left corner cutting through the adhesive and slide it into the left edges.
* Also you can apply heat again if you feel difficulty moving the pick.
* Make sure you don’t push your opening tool more than 2 mm deep on the left side or you might hit the two cables connecting the screen to your iPhone 15 Pro.
* Gently move your opening tool around the top left corner.
* Then slowly slide it down to the bottom left corner to cut the adhesive. Take your time with this part to avoid any damage.

Step #17. Separate the Adhesive from the Top Edge

* Gently move your opening tool around the top right corner.
* Be careful not to push your tool more than 3 mm deep along the top edge to avoid damaging anything inside.
* Then slide it along the top edge to release the two clips and loosen the adhesive. Take it slow to make sure everything comes apart smoothly.

Step #18. Prop up the Screen

* Set a small box or some books next to your iPhone 15 Pro to prop up the screen while you work on the cables.
* Gently lift the screen from the right side like you are opening a book.
* If it feels stuck use your opening tool to carefully go around the edges again and loosen any adhesive that is still holding it down.
* Make sure the screen stays propped up so you can safely reach the cables without pulling on them. Take it slow and steady.

Step #19. Open Logic Board Cover Screws

* The screen cables and battery connection are hidden inside the logic board cover. And it is fastened with the six screws.
* You need to use a Y000 screwdriver to unfasten four 1.6 mm long screws and two 1.3 mm long screws.
* Keep all the screws safely aside.
* Now turn the bottom of the logic board cover counterclockwise.
* Then carefully slide the top left corner out from under the ambient light sensor cable to remove the cover.
* Be gentle while doing this to avoid damaging any nearby components.

Step #20. Disconnect the Battery and Screen Cables

* At the bottom right corner of the logic board you will find the battery press connector.
* Pry up the battery press connector using an opening pick or a flat-tip spudger.
* Disconnect the battery.
* The screen cable is located at the center of the logic board.
* Pry up the screen press connector with an opening pick or a flat tip spudger and disconnect it from the logic board
* Now the third connector is the screen’s ambient lighting sensor.
* Carefully insert the tip of an opening pick under the ambient light sensor cable located near the top left corner of the logic board.
* Gently lift the cable to disconnect it. Make sure to be cautious to avoid damaging the delicate cable.
* Now the screen is free to remove completely from the iPhone 15 Pro.

The screen and back glass of the iPhone 15 Pro are now removed and ready for replacement.

However if you are replacing the screen it’s important to disconnect the battery before proceeding. You should only follow the screen replacement steps if you need to replace the iPhone 15 Pro screen.

For the back glass replacement follow the specific steps for that. Make sure to only do the steps that match the part you are replacing whether it’s the screen or the back glass.

Step #21. Reassemble the Back Glass of the iPhone 15 Pro

* Take out the new replacement back glass for the iPhone 15 Pro.
* The rear glass may come with the pre-installed adhesive.
* If it is not then you need to follow the further steps for applying new adhesive replacement on the back glass before setting it to connect cables.

How to Apply Adhesive on the Back Glass of the iPhone 15 Pro

* First of all clean the phone’s frame edges if you see their old adhesive.
* You can apply heat or isopropyl alcohol drops if you feel difficulty removing the old strips of the adhesive.
* Now take a replacement adhesive sheet and check it in the frame to make the idea about its cutouts.
* First place the adhesive sheet on the phone without removing the clear liner. Check the cutouts and spring contacts to get a clear idea of where everything fits.
* Once you are confident and understand the layout carefully peel off the clear liner from only the bottom of the adhesive.
* This exposes the sticky side for placing on the frame.
* Be extra careful because the adhesive is very sticky. If it touches the wrong spot, you will not be able to reuse the same sheet.
* Now gently start applying it from the bottom of the frame and work your way upward.
* Peel the adhesive liner gradually as you go. Continue until the adhesive is fully applied to the frame.
* Press the adhesive with your finger or a flat-tip spudger to make sure it’s secure. Finally remove the pink liner and you are ready to place the back glass.

Step #22. Set the Rear Glass in the Prop Up Position

* Place a stack of books or a small box under the back glass to hold it up while reconnecting the cables.
* Use a flat-end spudger to carefully connect the wireless charging coil. Once it is secure place the charging coil connector over the cables.
* Fasten the cover using its screw.
* Now align the rear glass on the frame.
* Now use tweezers to remove the final adhesive liner.
* Lift the back glass slightly to access the last adhesive liner on the right edge and peel it off carefully.
* If any of the back glass clips are bent gently straighten them with your fingers.
* Align the back glass with the phone’s frame and press the top edge until the clips snap-in.
* Finally press around all the edges to make sure the back glass is securely in place.

Step #23. Install New Screen to the iPhone 15 Pro

* The new screen usually comes along with the pre-install adhesive. If in your case there is no pre-installed adhesive you have to apply a new screen adhesive replacement on your own.
* But before this I need to clean the old adhesive from the frame.
Please be cautious while cleaning the frame. There are delicate spring contacts.

How to Apply New Screen Adhesive Replacement for the iPhone 15 Pro

* Check the adhesive strip by placing it on the frame to get an idea of how it fits paying attention to cutouts and spring contacts.
* Peel the blue film from the pull tab but only expose the bottom part.
Carefully apply this section to the frame.
* Slowly peel back the larger blue sheet as you continue to press the exposed adhesive onto the frame. Make sure it is aligning properly.
* Press the adhesive down firmly using your hand or a flat-end spudger to secure it well to the frame.
* Remove the top plastic liner that will leave the adhesive ready for the screen installation.

Step # 24. Reconnect the Screen Cables and Battery Cable

* Set the new replacement screen in the prop up Position.
* Connect the ambient lighting sensor to the logic board.
* Then connect the screen press cable connection to the logic board
* And in the end reconnect the battery press cable to the logic board.
* For reconnecting a press connector on your iPhone 15 Pro make sure it is lined up with the socket. Gently press down on one side until it clicks into place. Then do the same on the other side.
* Check that it is sitting flat as the rubber around the socket might stop it from connecting fully. Make sure everything is secure before continuing.

Step #25. Reassemble the Logic Board Cover and Fasten its Screws

* Carefully place the logic board cover in its slot.
* Please make sure the top left corner goes under the ambient light sensor cable.
* Now set it with your fingers.
* Fasten six screws of the logic board connection cover.
* Also make sure the right screws go to their whole from where they came out.

Step #26. Align the Screen on the iPhone 15 Pro Frame

* Peel off the last adhesive liner from the frame.
* Align the screen carefully with the phone’s frame and gently press down to help the adhesive stick.
* Make sure the screen is flush with the frame. Don’t leave any gap.
* Apply gentle but firm pressure to make sure the adhesive bonds properly between the screen and frame.

Step #27. Fasten Pentalobe Screws

* Locate the two small Pentalobe screw holes on either side of the charging port at the bottom of the phone.
* Use a P2 Pentalobe driver to insert and carefully tighten the screws.
* Avoid over lightning of the Pentalobe Screws.
* Press and hold the power button to turn on the iPhone 15 Pro after fastening the screws.
* Check the screen, touch sensitivity, and other components to make sure everything is functioning as expected.
