How to Repair iPhone 14 Pro
The iPhone 14 Pro features a durable Ceramic Shield display, but cracked screens are common. Repairs require careful handling of the Face ID sensors and display flex cables. Always disconnect the battery first to prevent short circuits.
Common Issues
- Screen replacement
- Battery replacement
- Camera lens cracked
- Face ID not working
How to Fix Common Issues
Screen replacement
Use a heat gun at 85°C on the edges for 2 minutes to soften adhesive. Insert a plastic pick between the frame and display. Work slowly to avoid damaging the Face ID flex cables. Transfer the front camera and sensors to the new display.
Battery replacement
Drain the battery below 25% before starting. Use isopropyl alcohol to dissolve the adhesive under the battery. Never pry with metal tools - puncture risk. Apply new adhesive strips when installing.
Camera lens cracked
The rear camera lens can be replaced separately. Heat the lens area and use a suction cup to pull the broken glass. Clean the adhesive and press the new lens into place.
Face ID not working
Face ID sensors are paired to the logic board. If you replaced the screen, ensure you transferred the front camera assembly. A damaged dot projector requires professional repair.

Repair Steps
Power Off and Prepare
Turn off the iPhone completely. Drain the battery below 25% to reduce fire risk. Gather a heat gun or iOpener, suction cup, plastic picks, Phillips screwdriver, and replacement screen.
Heat the Display Edges
Apply heat at 85°C (185°F) along the edges of the display for 2 minutes. This softens the adhesive securing the screen to the frame.
Create Opening with Suction Cup
Place the suction cup near the bottom of the screen. Pull gently while inserting a plastic pick between the display and frame. Work slowly around the perimeter to cut the adhesive.

Disconnect Display Cables
Lift the display at a 90-degree angle. Disconnect the three flex cables: display, digitizer, and front camera. Use a spudger to flip the connector latches. Never pull by the cables.
Remove Old Screen
Lift the display assembly away. Set it aside. Remove any adhesive residue from the frame with isopropyl alcohol.
Transfer Components
Transfer the front camera, speaker, and Face ID sensors from the old display to the new one. These are critical for Face ID to work.
Connect New Display
Connect the three flex cables to the new display. Ensure each connector is fully seated and the latches are closed.
Test Before Sealing
Power on the iPhone and test touch, display, and Face ID. Verify everything works before applying adhesive.
Apply Adhesive and Seal
Apply the included adhesive strip around the frame. Press the new display into place firmly. Wipe away any excess adhesive.
Final Test
Test all functions again: touch, Face ID, True Tone, and speaker. Allow adhesive to cure for 1 hour before heavy use.
