Overview
What this part is
At the top of the iPhone 12 Pro Max, behind the screen, the earpiece speaker sits on a flex cable that also carries the proximity sensor. The speaker plays the other person's voice when you hold the phone to your ear. The proximity sensor turns the screen off during calls so your cheek does not press buttons.
This part is the combined assembly: earpiece speaker and sensor flex together. If only the call audio is weak and the screen dims normally in calls, the standalone earpiece speaker may be all you need. Face ID faults are not fixed by this part.

Professional installation
How a technician fits this part
- Power the phone off, remove the bottom pentalobe screws and warm the screen edges.
- Open the display carefully and disconnect the battery.
- Remove the screen and take off the bracket over the earpiece at the top.
- Lift out the old earpiece and sensor flex, taking care of the nearby Face ID parts.
- Fit the new assembly, refit the screen and test calls and the proximity sensor.
- Apply new screen adhesive, close the phone and press evenly around the edges.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my iPhone 12 Pro Max?
Yes, if Settings › General › About shows iPhone 12 Pro Max. It fits models A2411, A2342, A2410 and A2412.
Does it fit the iPhone 12 Pro?
No. The iPhone 12 Pro Max uses its own earpiece assembly. It does not fit the iPhone 12, 12 Pro or 12 Mini.
What is the difference between this and the earpiece speaker only?
This assembly includes the sensor flex cable as well as the speaker, so it also fixes a proximity sensor that does not turn the screen off in calls. The standalone earpiece is the speaker only.
Is it made by Apple?
No. It is a brand new, OEM-quality earpiece speaker and sensor flex assembly made to fit the iPhone 12 Pro Max, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The screen must come off the iPhone 12 Pro Max, and the Face ID parts beside the earpiece are delicate.
How quickly will it arrive?
