earphone of iphone 12 mini is not working

Hi, thanks for reaching out! Try updating your iPhone to the latest software update available. If this does't fix anything you can check the speakers and microphone holes in the bottom of the iPhone to see if there's some dirt. Try to remove it with a wooden toothpick or visit an Apple Store or Apple certified repair shop and get support from there: https://getsupport.apple.com/

Kind regards.

Facing the same problem from today morning as i write this, service guys says the display needs to be changed which i find not at all a valid solution as even though that's the correct way of repairing it, i find it foolish to replace a fully functional display due to an earpiece issue. BTW even mine was 2 years old, Also read that 12 and 12 pro were having a solution for this and its free of cost even if it's out of warranty.
