Problem description
Here's how to fix an iPhone 8 that has a grayed out speaker icon during phone calls.
Please Note: Although the symptoms are similar to the iPhone 7/7Plus Audio IC failure, the solution is different.
Symptoms
- When you make a call, the speaker button is grayed out & you cannot click it.
- When trying to record a Voice Memo, it won't record.
Solution
Testing and Solution:
- Unplug the Front Facing Camera, then test again
- If the issue is solved, then plug in a new front-facing camera flex cable and try again
- Please note, replacing the Front Camera flex on iPhone 8 & 8 Plus, will make you lose True Tone.
Explanation:
Usually this is caused by the ALS or proximity sensors getting some corrosion from liquid damage.
It's easier to just replace the part, but sometimes, you can clean off the corrosion with a toothbrush and isopropyl alcohol and get the flex working again.
