iPhone 14 屏幕 更换

moderate45 minutes - 1 hour

If your iPhone 14 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 A2882 (international) model. If you're fixing a different iPhone 14 model, there may be some visual discrepancies, but the procedure should be the same.

Note: On iOS 17.6 and earlier, True Tone and auto brightness functionality is disabled after a screen replacement, even when using an original Apple screen. Face ID is also disabled, unless the iPhone is running iOS 15.2 or newer. On the latest iOS version, you can calibrate your new screen using Apple's [link|https://support.apple.com/en-us/120579|Repair Assistant|new_window=true] to restore True Tone functionality. This may happen automatically.

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.

If possible, turn on your device and test your repair before installing new adhesive and resealing.

To reassemble your device, follow these instructions in reverse order.

After your repair, depending on the replacement part, you may be able to [link|https://support.apple.com/en-us/120579|calibrate it using Apple's Repair Assistant|new_window=true], available as of iOS 18. Update your device, navigate to Settings General ***→***About Parts & Service History, tap Restart & Finish Repair, and follow the onscreen prompts.

The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the frame and place the screen back in its original position.
