Introdução
The Taptic Engine produces your iPhone's vibration and haptic feedback functions. Use this guide to remove and replace the Taptic Engine in an iPhone 14 Pro Max.
This guide was created using the A2894 (international) model. If you're fixing a different iPhone 14 Pro Max 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.
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.

Dominik, this is one of the best guides I've seen on the Taptic Engine replacement! I was looking on YouTube as well but many of the videos were not as in-detail as this guide. A big thank you! wordle solver
