my iphone 12 ear speaker not working

Try the following:

Click ▶︎ Update your iPhone. 📲

If that didn’t help, then try a Hard Reset:

1. Press volume up (quickly)
2. Press volume down (quickly)
3. Press and hold the power button until the Apple logo ( ) appears

If that didn’t work, it could be a hardware issue. ⚠️
