If your iPhone 14 Pro Max 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.
This guide was created using the A2894 (international) model. If you're fixing a different iPhone 14 model, there may be some visual discrepancies, but the procedure should be the same.
For your safety, discharge the battery below 25% before disassembling your device. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
Note: True Tone and auto brightness functionality are disabled after a screen replacement, even when using an original Apple screen. Face ID is also disabled unless the iPhone runs iOS 15.2 or newer.
You’ll need replacement adhesive to reattach the screen when reassembling the device. Your device will function normally, but will most likely lose its IP (Ingress Protection) rating.
